The largest family of snakes, comprising five subfamilies: Colubrinae, Natricinae, Homalopsinae, Lycodontinae, and Xenodontinae. They show a great diversity of eating habits, some eating almost anything, others having a specialized diet. They can be oviparous, ovoviviparous, or viviparous. The majority of North American snakes are colubrines. Among the colubrids are king snakes, water moccasins, water snakes, and garter snakes. Some genera are poisonous.

Role of mitochondrial dysfunction in the Ca2+-induced decline of transmitter release at K+-depolarized motor neuron terminals. (1/106)

The present study tested whether a Ca2+-induced disruption of mitochondrial function was responsible for the decline in miniature endplate current (MEPC) frequency that occurs with nerve-muscle preparations maintained in a 35 mM potassium propionate (35 mM KP) solution containing elevated calcium. When the 35 mM KP contained control Ca2+ (1 mM), the MEPC frequency increased and remained elevated for many hours, and the mitochondria within twitch motor neuron terminals were similar in appearance to those in unstimulated terminals. All nerve terminals accumulated FM1-43 when the dye was present for the final 6 min of a 300-min exposure to 35 mM KP with control Ca2+. In contrast, when Ca2+ was increased to 3.6 mM in the 35 mM KP solution, the MEPC frequency initially reached frequencies >350 s-1 but then gradually fell approaching frequencies <50 s-1. A progressive swelling and eventual distortion of mitochondria within the twitch motor neuron terminals occurred during prolonged exposure to 35 mM KP with elevated Ca2+. After approximately 300 min in 35 mM KP with elevated Ca2+, only 58% of the twitch terminals accumulated FM1-43. The decline in MEPC frequency in 35 mM KP with elevated Ca2+ was less when 15 mM glucose was present or when preparations were pretreated with 10 microM oligomycin and then bathed in the 35 mM KP with glucose. When glucose was present, with or without oligomycin pretreatment, a greater percentage of twitch terminals accumulated FM1-43. However, the mitochondria in these preparations were still greatly swollen and distorted. We propose that prolonged depolarization of twitch motor neuron terminals by 35 mM KP with elevated Ca2+ produced a Ca2+-induced decrease in mitochondrial ATP production. Under these conditions, the cytosolic ATP/ADP ratio was decreased thereby compromising both transmitter release and refilling of recycled synaptic vesicles. The addition of glucose stimulated glycolysis which contributed to the maintenance of required ATP levels.  (+info)

Basolateral regulation of pHi in isolated snake renal proximal tubules in presence and absence of bicarbonate. (2/106)

Intracellular pH (pHi) and its basolateral regulation were studied in isolated proximal-proximal and distal-proximal segments of garter snake (Thamnophis spp.) renal tubules with oil-filled lumens in HEPES-buffered and in HEPES-HCO-3-buffered media (pH 7.4 at 25 degrees C). pHi was measured with the pH-sensitive fluorescent dye 2',7'-bis(2-carboxyethyl)-5,6-carboxyfluorescein (BCECF) under resting conditions and in response to NH4Cl pulse. Resting pHi (approximately 7.1-7.2) and its response to and rate of recovery (dpHi/dt) from an NH4Cl pulse were not affected by the presence or absence of HCO-3 in either segment. Rate of recovery was depressed by Na+ removal in distal-proximal segments only and only in HEPES buffer. It was not affected by removal of Cl- or of both Na+ and Cl- or by reduction in membrane potential through addition of Ba2+ (5 mM) or high K+ (75 mM) in either segment in either HEPES or HEPES-HCO-3 buffer. The Na+/H+ exchange inhibitor ethylisopropylamiloride (EIPA) (100 microM) and the anion exchange inhibitor DIDS (100 microM) reduced dpHi/dt in the distal-proximal segments only and only in HEPES-HCO-3 buffer. The H+-ATPase inhibitor bafilomycin (1 microM), H+-K+-ATPase and K+/NH+4 exchange inhibitor Schering 28080 (10-100 microM), organic cation efflux inhibitor tetrapentylammonium (25 microM-20 mM), and K+ channel blocker tetraethylammonium (20 mM) had no effect on dpHi/dt in either segment. These data do not clearly support basolateral regulation of pHi in snake proximal renal tubules by commonly recognized Na+-dependent or Na+-independent acid or base transporters.  (+info)

Endocytic active zones: hot spots for endocytosis in vertebrate neuromuscular terminals. (3/106)

We have used a sensitive activity-dependent probe, sulforhodamine 101 (SR101), to view endocytic events within snake motor nerve terminals. After very brief neural stimulation at reduced temperature, SR101 is visualized exclusively at punctate sites located just inside the presynaptic membrane of each terminal bouton. The number of sites (approximately 26 sites/bouton) and their location (in register with postsynaptic folds) are similar to the number and location of active zones in snake motor terminals, suggesting a spatial association between exocytosis and endocytosis under these stimulus conditions. With more prolonged stimulation, larger SR101-containing structures appear at the bouton margins. Thus endocytosis occurs initially at distinct sites, which we call "endocytic active zones," whereas further stimulation recruits a second endocytic paradigm.  (+info)

Empty synaptic vesicles recycle and undergo exocytosis at vesamicol-treated motor nerve terminals. (4/106)

We investigated whether recycled cholinergic synaptic vesicles, which were not refilled with ACh, would join other synaptic vesicles in the readily releasable store near active zones, dock, and continue to undergo exocytosis during prolonged stimulation. Snake nerve-muscle preparations were treated with 5 microM vesamicol to inhibit the vesicular ACh transporter and then were exposed to an elevated potassium solution, 35 mM potassium propionate (35 KP), to release all preformed quanta of ACh. At vesamicol-treated endplates, miniature endplate current (MEPC) frequency increased initially from 0.4 to >300 s-1 in 35 KP but then declined to <1 s-1 by 90 min. The decrease in frequency was not accompanied by a decrease in MEPC average amplitude. Nerve terminals accumulated the activity-dependent dye FM1-43 when exposed to the dye for the final 6 min of a 120-min exposure to 35 KP. Thus synaptic membrane endocytosis continued at a high rate, although MEPCs occurred infrequently. After a 120-min exposure in 35 KP, nerve terminals accumulated FM1-43 and then destained, confirming that exocytosis also still occurred at a high rate. These results demonstrate that recycled cholinergic synaptic vesicles that were not refilled with ACh continued to dock and undergo exocytosis after membrane retrieval. Thus transport of ACh into recycled cholinergic vesicles is not a requirement for repeated cycles of exocytosis and retrieval of synaptic vesicle membrane during prolonged stimulation of motor nerve terminals.  (+info)

Signal transduction in the vomeronasal organ of garter snakes: ligand-receptor binding-mediated protein phosphorylation. (5/106)

The vomeronasal (VN) system of garter snakes plays an important role in several species-typical behaviors, such as prey recognition and responding to courtship pheromones. We (X.C. Jiang et al., J. Biol. Chem. 265 (1990) 8736-8744 and Y. Luo et al., J. Biol. Chem. 269 (1994) 16867-16877) have demonstrated previously that in the snake VN sensory epithelium, the chemoattractant ES20, a 20-kDa glycoprotein derived from electric shock-induced earthworm secretion, binds to its receptor which is coupled to PTX-sensitive G-proteins. Such binding results in elevated levels of IP3. We now report that ES20-receptor binding regulates the phosphorylation of two membrane-bound proteins with molecular masses of 42- and 44-kDa (p42/44) in both intact and cell-free preparations of the VN sensory epithelium. ES20 and DAG regulate the phosphorylation of p42/44 in a similar manner. ES20-receptor binding-mediated phosphorylation of p42/44 is rapid and transient, reaching a peak value within 40 seconds and decaying thereafter. Phosphorylation of p42/44 appears to be regulated by the countervailing actions of a specific membrane-bound protein kinase and a protein phosphatase. The phosphorylation of these membrane-bound proteins significantly reduces the activity of G-proteins as evidenced by a decrease in GTPase activity, but has little effect on ligand-receptor binding. These findings suggest that p42/44 play a role in modulating the signal transduction induced by ES20 in the vomeronasal system.  (+info)

Oral sensory papillae, chemo- and mechano-receptors, in the snake, Elaphe quadrivirgata. A light and electron microscopic study. (6/106)

The oral sensory papillae of the snake (Elaphe quadrivirgata), comprising a compound sensory system located along the tooth rows, were studied by light microscopy, immunohistochemistry for neuron specific enolase and S 100 protein, and scanning and transmission electron microscopy. Each sensory papilla exhibited a single taste bud and free nerve endings in the epithelium, and Meissner-like corpuscles, branched coiled terminals, and lamellated corpuscles in the connective tissue. The taste buds consisted of four types of cells; the type III cells, exclusively synapsing onto intragemmal nerves, were identified as gustatory in function. The gustatory cells included dense-cored and clear vesicles in the cytoplasm. These vesicles were accumulated both in the presynaptic and infranuclear regions, suggesting dual functions: the synaptocrine and paracrine/endocrine release of signal substances. The free nerve endings constantly contained mitochondria and frequent clear vesicles. The Meissner-like corpuscles were located in the uppermost zone of the connective tissue. These corpuscles consisted of nerve fibers and lamellar cells. The nerve fibers, rich in mitochondria, were folded and layered on each other. The branched coiled terminals were localized in the connective tissue along the side wall of the papillae. Nerve fibers, free from a Schwann-cell covering, swelled up to make terminals which accumulated mitochondria and glycogen particles. The lamellated corpuscles were associated with the nerve-fiber bundles in the connective tissue. Consisting of a central nerve axon and lamellar cells encircling it, these corpuscles resembled mammalian Vater-Pacini corpuscles, except that they lacked a capsule. These findings demonstrated that the snake sensory papilla represents one of the most specialized, compound sensory systems among vertebrates, which may play an important role in receiving chemical and mechanical information on prey.  (+info)

Effect of temperature on pH and electrolyte concentration in air-breathing ectotherms. (7/106)

The aim of this study was to determine the effects of temperature upon pH, protein charge and acid-base-relevant ion exchange in air-breathing ectotherms. Plasma and skeletal muscles in cane toads (Bufo marinus) and bullfrogs (Rana catesbeiana) were examined at 30, 20 and 10 degrees C. In addition, skeletal muscle ion concentrations were examined in black racer snakes (Coluber constrictor) at 30 and 10 degrees C. Cooling the amphibians produced a reduction in most of the plasma ion concentrations (Na(+), K(+), Ca(2+), Cl(-), SO(4)(2)(-)) and in protein concentration because of increased hydration. Between 30 and 10 degrees C, total plasma osmolality fell by 14 % in the toads and by 5 % in the frogs. Plasma protein charge, calculated using the principle of electroneutrality, was unaffected by temperature, except possibly for the toads at 10 degrees C. The in vivo skeletal muscle capdelta pHi/ capdelta T ratio, where pHi is intracellular pH and T is temperature, between 30 and 20 degrees C averaged -0.014 degrees C(-)(1) in the toads and -0.019 degrees C(-)(1) in the frogs. Between 20 and 10 degrees C, there was no change in pHi in the toads and a -0.005 degrees C(-)(1) change in the frogs. The in vitro skeletal muscle capdelta pHi/ capdelta T averaged -0.011 degrees C(-)(1) in both toads and frogs. In all three species, skeletal muscle inulin space declined with cooling. Intracellular ion concentrations were calculated by subtracting extracellular fluid ion concentrations from whole-muscle ion concentrations. In general, temperature had a large effect upon intracellular ion concentrations (Na(+), K(+), Cl(-)) and intracellular CO(2) levels. The relevance of the changes in intracellular ion concentration to skeletal muscle acid-base status and protein charge and the possible mechanisms producing the adjustments in intracellular ion concentration are discussed. It is concluded that ion-exchange mechanisms make an important contribution to adjusting pH with changes in temperature.  (+info)

Disruption of actin impedes transmitter release in snake motor terminals. (8/106)

To investigate the role of actin in vertebrate nerve terminals, nerve-muscle preparations from garter snake (Thamnophis sirtalis) were treated with the actin-depolymerizing agent latrunculin A. Immunostaining revealed that actin filaments within presynaptic motor terminal boutons were disrupted by the drug. In preparations loaded with the optical probe FM1-43, destaining was reduced by latrunculin treatment, suggesting that transmitter release was partially blocked. Latrunculin treatment did not influence the amplitude or time course of spontaneous miniature endplate potentials (MEPPs). Similarly, endplate potentials (EPPs) evoked at low frequency were comparable in control and latrunculin-treated curarized preparations. Brief tetanic stimulation of the muscle nerve (25 Hz, 90 s) depressed EPP amplitudes in both control and latrunculin-treated preparations. After tetanus, EPPs elicited at 0. 2 Hz in control preparations recovered rapidly (0-5 min) and completely (usually potentiating to above pre-tetanus levels; 130 +/- 11 %, mean +/- s.e.m.). In contrast, EPPs evoked in latrunculin-treated preparations recovered slowly (8-10 min) and incompletely (84 +/- 8 %). The influence of latrunculin on post-tetanic EPPs depended on its concentration in the bath (KD = 3. 1 microM) and on time of incubation. These observations argue that actin filaments facilitate transmitter release rather than impede it. Specifically, actin may facilitate mobilization of vesicles towards the releasable pools.  (+info)

The corn snake (Pantherophis guttatus) is a North American species of rat snake that kills small prey by constriction. Corn snakes are found throughout the southeastern and central United States. They are often kept as pets. They reach a moderate size of 3.9-6.0 feet (1.2-1.8 m). In the wild, they usually live around 6-8 years, but in captivity can live to be up to 23 years old[4] or longer.[5] Corn snakes look similar to the venomous copperhead snake and are often killed because of this similarity. Corn snakes are harmless and beneficial to humans.[6] They are one of the most common snakes kept as pets, alongside the garter snake and ball python. Corn snakes lack venom and help control populations of wild rodent pests that damage crops and spread disease.[7] They can be distinguished from copperheads by their brighter colors, slender build and lack of heat-sensing pits.[8] Although the corn snake is distinguished by its bright red orange colored scales, possible mutations can occur completely ...
DESCRIPTION: Brown tree snakes may be any length from 18 inches as juveniles to over 8 feet long as adults.

The San Francisco garter snake, a subspecies of the common garter snake, is found in scattered wetland areas on the San Francisco Peninsula from approximately the northern boundary of San Mateo County south along the eastern and western bases of the Santa Cruz Mountains, at least to the Upper Crystal Springs Reservoir, and along the Pacific coast south to Año Nuevo Point, and thence to Waddell Creek in Santa Cruz County.[2] It is difficult to obtain reliable distribution information and population statistics for the San Francisco garter snake, because of the elusive nature of this reptile and the fact that much of the remaining suitable habitat is located on private property that has not been surveyed for the presence of the snake. This subspecies is extremely shy, difficult to locate and capture, and quick to flee to water or cover when disturbed. The U.S. Fish and Wildlife Service has stated that many locations that previously had healthy populations of garter snakes are now in decline due to ...
Biologist Ron Larche says it will be about a year before they can estimate how many were lost. To try to get an estimate of the number of snakes still using the area, we will have to wait until next spring until we can do a mark recapture study and arrive at an estimate of the number of snakes still using the den, Larche said. We do know from a mark recapture study last year we had 65,000 snakes using the area. The snake dens in Manitobas Interlake are in a protected wildlife management area. The site is a unique feature that has attracted visitors from around the world. Larche says officials are consulting with international snake experts to try to figure out what happened. He says biologists believe the reptiles died of natural causes. ...

The heating mats are used for the tanks to provide heat inside the tanks where the corn snakes live. These heating mats are placed under the tanks to supply heat for the corn snakes inside them. The heating mat has temperature adjustment which is a very important part and helps maintain the temperature that is important for the corn snakes to perform various activities. The heat helps them to be free from diseases and live a happy and healthy life.. The heating mat provides them with a comfortable environment so that they do not feel suffocated inside the tanks and feel homely and this helps in enhancing their mood and they will also maintain a healthy relationship with their owners and be a good company to them. The apt temperature for the corn snake for basking is 90 degrees Fahrenheit, the ambient temperature is 78 degrees to 82 degrees Fahrenheit and in order to maintain this apt temperature for your corn snake, you need to provide them with a heating mat whenever the temperature comes lower ...

The Common Garter Snake has been said to be the best-studied snake in the world. Among other studies, its interaction with the Rough-skinned Newt is perhaps the most interesting. These newts are extremely poisonous, the tetrodotoxin in their body enough to kill anything that tries to eat them (including even large mammals). Some populations of garter snakes have evolved physiological defenses against this toxin and can eat newts freely. Other populations cannot. This is said to be an arms race between predator and prey, the prey evolving defenses and the predator evolving mechanisms of countering them ...

Throughout much of the newts range, the common garter snake (Thamnophis sirtalis) is resistant to the newts toxin. In several populations, these snakes successfully prey upon the newts. Toxin resistant garter snakes are the only known animals today that can eat a T. granulosa newt and survive. This is an example of co-evolution.[2] The snakes resistance to the toxin has resulted in a selective pressure that favours newts which produce more potent levels of toxin. Increases in newt toxicity then apply a selective pressure favouring snakes with mutations conferring even greater resistance. This cycle of a predator and prey co-evolving is sometimes called an evolutionary arms race. In this case it results in the newts producing levels of toxin far in excess of what is needed to kill any other conceivable predator.[3] ...
The term venom has been somewhat misunderstood by both the lay public and by many scientists, and it seems useful here to define what is meant by a venom, as there is also disagreement as to its application to the Duvernoys secretion of colubrid snakes. I find the definition of Russell to be reasonably inclusive and most useful: the toxic substance produced by a plant or animal in a highly developed secretory organ or group of cells. . .which is delivered during the act of biting or stinging. An important distinction of this definition is that it defines a route of administration (roughly, injection) and that it allows for a venom to be composed of one to many toxins. For much of the lay public, venom is synonymous with toxin; this incorrect usage of terminology has served to cloud issues concerning venomous animals and on occasion has lead to incorrect application of snakebite management techniques. ...

Dr. Robert Mason has been studying a mysterious phenomenon for over fifteen years: the reemergence of tens of thousands of red-sided garter snakes — the world’s largest concentration of snakes — after a winter spent in a state of suspended animation in subterranean caverns. This gathering each spring in the forests of Manitoba, Canada, is one of the most extraordinary events of the natural world and is the subject of study for Dr.
I honestly think of this like L. Syspila. It is completely different than L. Triangulum Triangulum but both, at a time, lumped together as both L. Triangulum, with Syspila (then considered a subspecies) in the bottom half of Illinois and Triangulum in northern Illinois and a kind of mix in Central. I believe that Syspila is a different species than Triangulum, they both look very different in coloration and overall shape and size. I am not sure about genetics and/or the species itself and how its represented (but I think now Syspila is its own Species). I do not believe that T. Sirtalis Semifaciatus is a valid subspecies, same with T. Sirtalis Parietalis. I have seen parietalis traits (the red dots on the sides) in Sirtalis in Cook County, where parietalis doesnt occur. Sure, color variants do exist but as Syspila is also different in size,the only difference in parietalis from Sirtalis is that they have red sides, which have been seen by myself in Cook County exhibited in some specimen of ...
I was in my backyard this evening here in Wisconsin and almost stepped on a hog-nosed that was curled up in the grass. When I looked closer it lying over a hole in the ground and appeared to have been trying to go down the hole into the ground. I went into the house to get my camera and the snake wasnt there when I came back. It waited thinking it was down the hole and while I watched a small bee came out of the hole. I eventually found the snake about 20 yards away and watched it move through the grass, it appeared to be hunting. It followed a circular path and moved back to the same spot where I had first seen it and went into the hole. The snake was about 21/2 feet long and only the front half could get into the hole. It remained that way for over an hour with the front half squirming in the hole. After a while the bee I had seen earlier came back and was trying to find its way into the hole but couldnt because of the snake. The bee eventually was able to go into the hole along side the ...

The first two of those features are not found in any other known snake in the family Colubridae in the Western Hemisphere. Colubridae is the largest snake family and includes just over 51 percent of all known living snake species.. Utilizing the vast resources of UTAs Amphibian and Reptile Diversity Research Center for comparative purposes, the researchers made CT scans of dozens of specimens of snakes. The biologists believe that due to some of the specimens physical features, Cenaspis is likely a burrowing snake that feeds on insects and spiders. Campbell believes that Cenaspis is not extinct but has eluded capture due to its burrowing lifestyle and other elusive habits.. This provides evidence of just how secretive some snakes can be, Campbell told National Geographic, which ran a story about the discovery in its Dec, 19, 2018, edition. Combine their elusive habits with restricted ranges and some snakes do not turn up often.. He noted said that because of the snakes unique nature, the ...

Garter snakes, sometimes called garden snakes, are small nonpoisonous snakes that live in your yard. There are different varieties, but the most common have subtle colors. Usually they have dark but soft hues of black or green, with a yellow or red set of stripes running the length of their backs.
In order to elucidate the phylogenetic relationships in European ratsnakes of the genus Elaphe, we analyzed a 597 bp part of the mitochondrial cytochrome b gene of eight West Eurasian and one East Asian species. Lampropeltis served as outgroup. Maximum parsimony and maximum likelihood suggest the existence of four lineages: 1) E. scalaris; 2) the E. longissima species group comprising E. longissima, E. lineata, E. situla, E. hohenackeri, and E. persica; 3) E. quatuorlineata and 4) E. dione as a sister group to 3). Elaphe scalaris is basal and shows no closer affiliation with any other analyzed species. The Middle Eastern E. persica and E. hohenackeri appear basal within the E. longissima group. Elaphe lineata differs by 8% nucleotide substitutions from E. longissima, supporting the hypothesis that both taxa represent distinct species. Elaphe situla is associated with Elaphe longissima and E. lineata. Three analyzed subspecies of E. quatuorlineata are represented by distinct haplotypes. The extent of

There is currently a debate concerning the definition of the taxon Tetrapoda, which is part of a wider debate dealing with the definiton of phylogenetic groups. Many papers over recent years (eg. Gauthier et al., 1989, Rowe, 1988, Rowe et al., 1992, de Queiroz et al., 1992) have suggested that a phylogenetic, or node-based, definition, is more rigorous than one which employs a key-character, with both a crown-group definition (Altangerel et al., 1993, Norell and Novacek, 1992, Norell et al., 1993, Lebedev and Coates 1995) and a total-group definition (Patterson, 1993, Coates, 1996) having its adherents. In the case of the Tetrapoda, the crown-group would encompass the clade containing all the modern representatives, namely the Amphibia and the Amniota, plus any fossil taxa falling above the node in the cladogram representing their nearest common ancestor. In that case, Tetrapoda would exclude any fossil taxon which falls outside this grouping, independent of the possession of any key ...

Infestations of the brown tree snake (Bioga irregularis) have led to the extirpation of all but two of the 12 native forest birds on the island of Guam. In addition, the snakes have caused millions of dollars in damage to the islands electrical power distribution system. An anticipated increase in the U.S. military presence on Guam will increase the flow of outbound cargo that could overtax the present operational control methods, such as trapping, hand capture, and canine inspection of outbound cargo, that deter the spread of snakes from Guam to other locations that are conducive to the snakes establishment, including Hawaii ...
The frequently feeding and actively hunting garter snake regulates mucosal thickness in response to functional demands, i.e. feeding versus fasting. The patterns and dynamics of up- and downregulation of small intestine size were the same as described previously for Burmese pythons (Starck and Beese, 2001). Up- and downregulation of small intestine size and liver size were rapid, repeatable and reversible. In pythons, the mucosal thickness of fasting animals increased threefold within 2 days after feeding. Here, we observed only 1.5-fold size changes, but comparisons were made with an actively absorbing intestine, so the responses were relatively small. If we compare small intestinal mucosal thickness of group 1 with that of group 2, the digesting mucosa thickness is approximately 200% of that of fasting snakes.. The mucosal epithelium is a transitional epithelium that has the same pseudostratified configuration in the fasting snake as described previously for Burmese pythons (Starck and Beese, ...

The extent of amino acid racemization in Chione, Tivela, Mytilus, and Protothaca shells has been analyzed to estimate ages of seven raised marine terrace sites in San Diego County, California. Sites at Scripps and Crown Point are correlated with the Nestor terrace (120,000 yr old). Sites at Del Mar, Tecolote Creek, and Border Park are estimated to be about 200,000 yr old. A site at Morena Boulevard is somewhat more than 300,000 yr old, and a Linda Vista terrace site is too old to be dated by this method.. The ages of terraces derived in this and previous studies demonstrate tectonic activity in the area and suggest the need for reassessment of geomorphic correlations and for comparison of fossil assemblages of similar age for paleobiogeographic interpretation. Amino acid dating is a useful method for estimating the ages of raised marine terraces a few hundred thousand years old. ...
This experiment in the famed garter snake caverns of Manitoba, Canada, was one of the first in a field setting to ever quantify the effects of estrogen as a stimulant of pheromones, scientists said, in research just published in the Journal of Experimental Biology.. This estrogen, they said, is the same exact chemical found in many animal species, ranging from snakes to amphibians, fish, mammals and humans. The research confirms once again the unusually powerful role that estrogen can play in biology, and is also relevant to widespread concern about the environmental impact of compounds that mimic the effect of estrogen, found in some chemicals and pesticides.. In this study, male snakes were implanted with a small capsule that raised their estrogen level to about that of female snakes. After one year of this estrogen supplementation, the male snakes exuded a pheromone that caused other males to swarm to them and form the writhing mating balls that this species of garter snake is known ...

The chromatophores are extremely abundant, and can be differentiated into three types, small disc shaped bodies in the upper part of the stratum spongiosum 1-5 μm across, a middle layer of irregular spheroid to ovoid cells, with a granular interior made up of two types of granules (smaller irregular sub-spherical granules and larger rounded granules), and a lower layer comprising larger smooth surfaced ovoid cells with prominant lateral processes. These are interpretted as being different types of chromatophores based upon comparison with living Snakes, with an upper layer of iridophores (reflective, irridescent cells), a middle layer of xanthophores (cells contianing yellow carotenoid pigments) and erythrophores (cells contianing orange pteridine pigments), and a base layer comprising melanophores (cells with black or dark brown melanin pigments ...
A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood - attracting dozens of other males eager to mate..

Cobras are elapid snakes-members of the Elapidae family. The elapids are a family of venomous snakes found in tropical and subtropical regions around the world, including the Indian Ocean and the Pacific. They are characterized by possessing a set of hollow, fixed fangs through which they inject venom, and come in a wide range of sizes, from only 18 cm (Drysdalia) up to 6 m in length (King cobra, Ophiophagus). Myers et al. (2006a) recognize 46 genera of elapids, while the Integrated Taxonomic Information System (ITIS) lists 61 genera with 231 species. In addition to cobras, the Elapidae includes the taipans, brown snakes, tiger snakes, fierce snakes, coral snakes, mambas, sea snakes, and others.. Outwardly, terrestrial elapids look similar to the colubridae: almost all have long and slender bodies with smooth scales, a head that is covered with large shields and not always distinct from the neck, and eyes with round pupils. In addition, their behavior is usually quite active and most are ...

The finch species represent birds that differ very little from each other in any significant way, as is recognized in the relevant literature. The finches retain the ability to interbreed and produce viable, fertile hybrids (Jeffrey Podos and Stephen Nowicki, Beaks, Adaptation, and Vocal Evolution in Darwins Finches, BioScience, Vol. 54(6):501-510 (June 2004)). It has also been documented that that several of Galápagos finch species are known to interbreed in the wild (Peter R. Grant and B. Rosemary Grant, Unpredictable evolution in a 30-year study of Darwins finches, Science, Vol. 296:707-711 (2002)). Now of course interbreeding is not the be all and end all of speciation, but the ability to interbreed indicates how close the species are to each other-more akin to varieties of dogs than to dogs v. foxes ...

All elapids have a pair of proteroglyphous fangs used to inject venom from glands located towards the rear of the upper jaws. In outward appearance, terrestrial elapids look similar to the Colubridae: almost all have long and slender bodies with smooth scales, a head covered with large shields and not always distinct from the neck, and eyes with round pupils. In addition, their behavior is usually quite active, and most are oviparous. Exceptions to all these generalizations occur: e.g. the death adders (Acanthophis) include short and fat, rough-scaled, very broad-headed, cat-eyed, live-bearing, sluggish ambush predators with partly fragmented head shields.. Some elapids are strongly arboreal (African Pseudohaje and Dendroaspis, Australian Hoplocephalus), while many others are more or less specialised burrowers (e.g. Ogmodon, Parapistocalamus, Simoselaps, Toxicocalamus, and Vermicella) in either humid or arid environments. Some species have very generalised diets (euryophagy), but many taxa have ...

A synthesis of previous work and new data on the stratigraphy of high terraces of the Ohio and Monongahela Rivers upstream from Parkersburg, West Virginia, indicates a correspondence between terrace histories in the ancient Teays and Pittsburgh drainage basins. Four terraces are identified in each. Sediments of the lower three alluvial and slackwater terraces, correlated with Illinoian, early Wisconsin, and late Wisconsin glacial deposits, have been traced along the modern Ohio River through the former divide between the Teays and Pittsburgh basins. Sediments in the fourth terrace, the highest well-defined terrace in each basin, were deposited in two ice-dammed lakes, separated by a divide near New Martinsville, West Virginia. Some deposits of the highest slackwater terrace in both the Teays and Pittsburgh basins have reversed remanent magnetic polarity. This, and the stratigraphic succession in the two basins, suggests that both were ponded during the same glaciation. Reversed polarity in these ...

of woodland caribou could be found on a small collection of islands on Lake Superior just south of the town of Terrace Bay, Ontario. I found this intriguing. Really? Woodland caribou? This came as a surprise to me, as I had thought that their presence now only extended to the upper reaches of Lake Nipigon and beyond. How did they arrive on these islands? Apparently via ice bridges that formed on rare occasions (even rarer now) over the distant years when the lake froze over in winter. Perhaps this tidbit was passed on to me in the summer of 1988 while I was a student working in Terrace Bay, shortly after the islands had been granted provincial park status by the Ontario government. I was already accustomed to some locals regaling me with what they considered to be serious accounts of their heroic hunting (e.g., I felled 2 moose with one shot of my 12 gauge and they both toppled neatly into the back of my pickup truck), and other outdoor pursuits - so I knew enough to be a bit skeptical. Yet ...

The rough-skinned newts poison has an unlikely counter. Of all things, the common garter snakes in the newts habitat are the only things that can eat the toxic not-lizards. These are not impressive snakes to look at, but they have evolved such that the binding feature in tetrodotoxin cannot work its deadly magic. The two are in an arms race so fierce that the snake keeps evolving stronger and stronger counters to stronger and stronger pufferfish poison ...

Its advantageous for a female snake to mate with as many males as she can, so that she has a wide variety of sperm to choose from. Female adders with more mates have higher offspring survival, probably due to less inbreeding and more genetic diversity to choose from, especially in regions of the genome where diversity is important, such as the MHC, which codes for proteins involved in recognizing pathogens and initiating an immune response. Many species, including humans, select their mates at least partly on the basis of MHC dissimilarity (which they can judge by smell), and this may also be the case in snakes. However, many male and female snakes often have pretty limited time to get together, since theyre only in the same place at the same time for short periods in spring and fall when theyre entering and leaving hibernation sites, which might mean that they have to make rapid decisions about who to mate with. However, a recent paper by Rulon Clark and others showed that male Western ...

Several approaches to dating were attempted, and our research on this topic continues. At Preveli 2, east of the Preveli Gorge, Palaeolithic artifacts are associated with a flight of marine terraces resulting from relatively high sea levels in the Pleistocene that were preserved by subsequent rock uplift. The lowest late Pleistocene marine terraces resulting from high stands of the sea at Preveli (14 ± 1 masl) and Schinaria (21 ± 1 masl) have 2-sigma calibrated radiocarbon ages of 45,400 ± 1,600 and 49,120 ± 2,890 years b.p., respectively, and are correlated with Marine Isotope Stages 3.3 and 3.4, both eustatic high stands. The higher terraces, at 59 and 96 masl, are unquestionably older. How much older? Assuming similar rates of rock uplift (1.4 ± 0.1 m/kyr) determined from the age-elevation relationships of the dated terraces at 14 and 21 masl, it is possible to estimate the approximate ages of the terraces associated with artifacts. This correlation provides an approximate age for the ...
Tens of thousands of red sided garter snakes appear here Narcisse, Manitoba on spring season. It is their annual mating ritual that draws thousands of people to visit the Canadian province.The area around Narcisse is so attractive to snakes for the same reasons many farmers abandoned it decades ago: Its thin topsoil sits on top of limestone that water has gradually eroded underground, creating a network of small caves that can be entered through sinkholes.</blockqu...

Just above the northern reaches of the Phoenix megalopolis lies the Agua Fria National Monument, named for the river that runs through it and known for its rich archeological history and the refuge it provides for a broad range of wildlife species, including the imperiled Gila chub, yellow-billed cuckoo and northern Mexican garter snake. Its a wonderful monument, with grass covered mesas and many miles of riparian areas within its borders.. Unfortunately, and even after years of public process following Arizona Game and Fish Departments purchase of the base property, the Bureau of Land Management seems to be more than willing to see this unique wildlife habitat as an untapped opportunity to expand livestock use of the monument lands. In June, the agency issued a decision to add nearly twenty miles of water pipeline, new wells, tanks and troughs, and drain up to 200,000 gallons of water from nearby riparian areas to benefit the livestock industry. The project would also have authorized the use ...

In our examples of how cats have protected their owners, this could well be via protection from dangers. A kind of â negotiation contractâ is developed during the bonding process between a cat and its owner. Interestingly, cats remember acts of kindness and return the favors later on.

The San Francisco garter snake, a subspecies of the common garter snake, is found in scattered wetland areas on the San Francisco Peninsula from approximately the northern boundary of San Mateo County south along the eastern and western bases of the Santa Cruz Mountains, at least to the Upper Crystal Springs Reservoir, and along the Pacific coast south to Año Nuevo Point, and thence to Waddell Creek in Santa Cruz County.[2] It is difficult to obtain reliable distribution information and population statistics for the San Francisco garter snake, because of the elusive nature of this reptile and the fact that much of the remaining suitable habitat is located on private property that has not been surveyed for the presence of the snake. This subspecies is extremely shy, difficult to locate and capture, and quick to flee to water or cover when disturbed. The U.S. Fish and Wildlife Service has stated that many locations that previously had healthy populations of garter snakes are now in decline due to ...

The discovery of three new species of Synophis snakes from the eastern slopes of the tropical Andes in Ecuador and Peru is reported. All previous records of S. bicolor from eastern Ecuador correspond to S. bogerti sp. n., which occurs between 1000-1750 m along a large part of the Amazonian slopes of the Ecuadorian Andes. In contrast, Synophis zamora sp. n. is restricted to southeastern Ecuador, including Cordillera del Cóndor, between 1543-1843 m. Synophis insulomontanus sp. n. is from the eastern slopes of the Andes in central and northern Peru, between 1122-1798 m, and represents the first record of Synophis from this country. All three new species share in common a large lateral spine at the base of the hemipenial body. A molecular phylogenetic tree based on three mitochondrial genes is presented, including samples of Diaphorolepis wagneri. Our tree strongly supports Synophis and Diaphorolepis as sister taxa, as well as monophyly of the three new species described here and S. calamitus. Inclusion of
