Analyses of oviductal pars recta-induced fertilizability of coelomic eggs in Xenopus laevis. (1/166)

The acquisition of fertilizability in coelomic eggs of Xenopus laevis has been shown to be correlated with the physical, biochemical, and ultrastructural alterations of the egg envelope [coelomic envelope (CE)] induced during the passage of eggs through the pars recta portion of the oviduct. However, no direct evidence that the pars recta renders eggs fertilizable has yet been presented. In this study, we show that coelomic eggs are highly fertilizable when they are incubated with continuous shaking for 4 h at 15 degrees C in pars recta extract (PRE) derived from females prestimulated by pregnant mare serum gonadotropin. The PRE from pituitary-stimulated Bufo japonicus was as potent as homologous PRE in rendering Xenopus eggs fertilizable. Incubation of coelomic eggs in PRE for 30 min induced a dramatic increase in the rates of sperm binding to the envelope to a level equivalent to that exhibited by the envelope from uterine eggs (VEs). The CE-to-VE ultrastructural conversion and a 43k-to-41k hydrolysis of the envelope glycoprotein component started 5 min after, and were completed by 15 min after, the start of incubation in PRE and were accompanied by an exposure of a new N-terminal sequence typical to gp41. Thus, the biochemical and ultrastructural conversions and the sperm-binding activity of the envelope induced by PREs, although being prerequisite, were not sufficient to render coelomic eggs fully accessible to fertilizing sperm.  (+info)

Neuromuscular control of prey capture in frogs. (2/166)

While retaining a feeding apparatus that is surprisingly conservative morphologically, frogs as a group exhibit great variability in the biomechanics of tongue protraction during prey capture, which in turn is related to differences in neuromuscular control. In this paper, I address the following three questions. (1) How do frog tongues differ biomechanically? (2) What anatomical and physiological differences are responsible? (3) How is biomechanics related to mechanisms of neuromuscular control? Frog species use three non-exclusive mechanisms to protract their tongues during feeding: (i) mechanical pulling, in which the tongue shortens as its muscles contract during protraction; (ii) inertial elongation, in which the tongue lengthens under inertial and muscular loading; and (iii) hydrostatic elongation, in which the tongue lengthens under constraints imposed by the constant volume of a muscular hydrostat. Major differences among these functional types include (i) the amount and orientation of collagen fibres associated with the tongue muscles and the mechanical properties that this connective tissue confers to the tongue as a whole; and (ii) the transfer of intertia from the opening jaws to the tongue, which probably involves a catch mechanism that increases the acceleration achieved during mouth opening. The mechanisms of tongue protraction differ in the types of neural mechanisms that are used to control tongue movements, particularly in the relative importance of feed-forward versus feedback control, in requirements for precise interjoint coordination, in the size and number of motor units, and in the afferent pathways that are involved in coordinating tongue and jaw movements. Evolution of biomechanics and neuromuscular control of frog tongues provides an example in which neuromuscular control is finely tuned to the biomechanical constraints and opportunities provided by differences in morphological design among species.  (+info)

Genetic variation as a test of natural selection. (3/166)

Allozymic variation encoded by 26 loci was analyzed electrophoretically in 507 specimens representing 12 populations of green toads, Bufo viridis, in Israel and the Vis Adriatic Island. Genetic variation in Bufo viridis is higher than in any vertebrate yet studied. Mean heterozygosity per locus per individual (H) is 0.133 (range, 0.105 to 0.159). H is higher in central populations as compared with isolates, and varies among four major protein classes, being highest in transferases and hydrolases and lowest in oxidoreductases and nonenzymatic proteins. Differential gene frequencies among polymorphisms was tested as an indicator of natural selection. Significant heterogeneity between loci in their apparent inbreeding coefficients Fe=S-2p/P(1-p) was found for all alleles and for each of the four major classes of proteins tested, which may be taken as evidence of selection. Both uniform and diversifying selection are suggested by the low and high Fe values, respectively. The general pattern of high heterozygosity in Bufo viridis is best explained as an adaptive strategy in heterogeneous environments.  (+info)

Differences in the skin peptides of the male and female Australian tree frog Litoria splendida. The discovery of the aquatic male sex pheromone splendipherin, together with phe8 caerulein and a new antibiotic peptide caerin 1.10. (4/166)

The skin secretions of female and male Litoria splendida have been monitored monthly over a three-year period using HPLC and electrospray mass spectrometry. Two minor peptides are present only in the skin secretion of the male. The first of these is the female-attracting aquatic male sex pheromone that we have named splendipherin, a 25 amino acid peptide (GLVSSIGKALGGLLADVVKSKGQPA-OH). This pheromone constitutes about 1% of the total skin peptides during the breeding season (January to March), dropping to about 0.1% during the period June to November. Splendipherin attracts the female in water at a concentration of 10-11-10-9 M, and is species specific. The second peptide is a wide-spectrum antibiotic of the caerin 1 group, a 25 residue peptide (GLLSVLGSVAKHVLPHVVPVIAEKL-NH2) named caerin 1.10. The neuropeptides of L. splendida are also seasonally variable, the change identical for both the female and male. During the period October to March, the sole neuropeptide present in skin secretions is caerulein [pEQDY(SO3)TGWMDF-NH2]; this is active on smooth muscle and is also an analgaesic. During the southern winter (June to September), more than half of the caerulein is hydrolysed to [pEQDYTGWMDF-NH2], a peptide that shows no smooth muscle activity. In place of caerulein, a new peptide, Phe8 caerulein [pEQDY(SO3)TGWFDF-NH2], becomes a major component of the skin secretion. Perhaps this seasonal change is involved in thermoregulation, that is, with the initiation and maintenance of the inactive (hibernation) phase of the animal.  (+info)

Isolation, structural characterization, and bioactivity of a novel neuromedin U analog from the defensive skin secretion of the Australasian tree frog, Litoria caerulea. (5/166)

We report the isolation of a novel bioactive peptide, neuromedin U-23 (NmU-23), from the defensive skin secretion of the Australasian tree frog, Litoria caerulea. The primary structure of the peptide was established by a combination of microsequencing, mass spectroscopy and site-directed antiserum immunoreactivity as SDEEVQVPGGVISNGYFLFRPRN-amide (M(r) 2580.6). A synthetic replicate of frog NmU-23 displaced monoradioiodinated rat NmU-23 from uterine membranes in a dose-dependent fashion indistinguishable from nonisotopically labeled rat NmU-23. In a rat uterine smooth muscle strip preparation, synthetic frog NmU-23 produced dose-dependent contractions identical to porcine NmU-25. However, in a preparation of human urinary bladder muscle strip, the synthetic frog peptide was more potent than porcine NmU-25 in eliciting contraction and produced desensitization of the preparation to the latter peptide. This report demonstrates that the defensive skin secretion of a frog contains a novel peptide exhibiting a high degree of primary structural similarity to the endogenous vertebrate peptide, NmU, and that this frog skin analog displays biological activity in mammalian tissues.  (+info)

Actin-like filaments amd membrane rearrangement in oxyntic cells. (6/166)

The secretory pole of vertebrate oxyntic cells possesses two distinct membrane systems: the apical plasma membrane which presents numerous infoldings, microvilli and processes, and a complex tubulovesicular system located in close proximity to the plasma membrane. These two membrane systems are generally believed to be interconvertible in relation to the functional state of the cell. To determine the role that filaments may play in the interconversion process, the secretory pole of rat and toad oxyntic cells was examined by electron microscopy under conditions designed to demonstrate filamentous structures, i.e., slight cellular swelling and incubation with heavy meromyosin. Filaments 50-80 A in diameter are present in close association with the plasma membrane to which they are connected by regularly spaced bridges. Heavy meroxyosin-treated material reveals "decorated" filaments in topographically corresponding locations. No filaments are seen in association with membranes of the tubulovesicular system. These findings suggest that association with actin-like filaments is a step in the translocation of membranes from the tubulovesicular system to the plasma membrane.  (+info)

Thyroid hormone-dependent metamorphosis in a direct developing frog. (7/166)

The direct developing anuran, Eleutherodactylus coqui, lacks a tadpole, hatching as a tiny frog. We investigated the role of the metamorphic trigger, thyroid hormone (TH), in this unusual ontogeny. Expression patterns of the thyroid hormone receptors, TRalpha and TRbeta, were similar to those of indirect developers. TRbeta mRNA levels increased dramatically around the time of thyroid maturation, when remodeling events reminiscent of metamorphosis occur. Treatment with the goitrogen methimazole inhibited this remodeling, which was reinitiated on cotreatment with TH. Despite their radically altered ontogeny, direct developers still undergo a TH-dependent metamorphosis, which occurs before hatching. We propose a new model for the evolution of anuran direct development.  (+info)

Maculatin 1.1, an anti-microbial peptide from the Australian tree frog, Litoria genimaculata solution structure and biological activity. (8/166)

The dorsal glands of Australian tree frogs from the Litoria species contain a diversity of antibiotic peptides that forms part of the defence system of the animal. Here, the antibiotic activity and structure of maculatin 1.1, a 21 amino acid peptide from Litoria genimaculata, are compared. The activity data on maculatin 1.1 and a series of its analogues imply that the mechanism of action of maculatin 1.1 involves binding to, and subsequent lysis of, the bacterial cell membrane. The structure of maculatin 1.1 was determined using NMR spectroscopy in a trifluoroethanol/water mixture and when incorporated into dodecylphosphocholine micelles. Under both conditions, the peptide adopts a very similar conformation, i.e. a helical structure with a central kink in the vicinity of Pro15. The kink allows the peptide to adopt a well-defined amphipathic conformation along its entire length. The similar structures determined under both solvent conditions imply that structures of membrane-interacting peptides in trifluoroethanol/water mixtures are representative of those adopted in a membrane environment, e.g. when incorporated into micelles. The synthetic Ala15 analogue of maculatin 1.1 has markedly reduced activity and its NMR-derived structure is a well-defined helix, which lacks the central kink and flexibility of the parent molecule. It is concluded that the kink is important for full biological activity of the peptide, probably because it allows maximum amphipathicity of the peptide to facilitate interaction with the membrane. The structure of maculatin 1.1 is compared with a related peptide, caerin 1.1 [Wong, H., Bowie, J.H. and Carver, J.A. (1997) Eur. J. Biochem. 247, 545-557], which has an additional central proline residue and enhanced central flexibility compared with maculatin 1.1. The role of central flexibility within antibiotic peptides in their interaction with bacterial membranes is discussed.  (+info)

Antimicrobial peptides in skin secretions of toads are promising methods to combat a wide spectrum of bacteria. Histone H2A is a type of DNA-binding protein that acts as a precursor for several antimicrobial peptides. In toads (family Bufonidae) buforin I and buforin II are examples of antimicrobial peptides that derived from histone H2A. This study investigated the genetic diversity and phylogenetic analysis and in silico prediction of antimicrobial peptides derived from histone H2A of Duttaphrynus melanostictus and Phyrinoidis asper, which were collected from Bogor Agricultural Universitys campus area. A new set of primers (Buf_fwd and Buf_rev) were designed by using PrimerBLAST, to amplify 393 nucleotides of the histone H2A gene that codes 131 amino acids. Haplotype diversity of both species are very low. Phylogenetic analysis shows the sample D. melanostictus and P. asper are separated to each other in two different clades. Several short predicted peptides from histone H2A show a potential ...

4; SD = 4.4). 4. Discussion. The results of this study indicated seasonal differences in the diet of Physalaemus cf. cicada. These differences can be related not only to the prey availability, but also to the changes in the composition of the community of active anurans. In both seasons, P. cf. cicada presented a diet based mainly on Isoptera and Formicidae. In the rainy season, the number of termites found in gastrointestinal tracts was smaller than in the dry season, probably due to their lower availability in the environment, and due to the presence of B. granulosus in the same season, since this species also consumed the same kind of food in large amounts. Furthermore, we found a significative positive correlation between the individual size of P. cf. cicada and maximum volume of consumed prey only in the rainy season.. Formicidae presented the largest abundance in the environment, but the frequency of occurrence and the numeric frequency were proportionally small when compared to their ...

A recent publication in Biology Letters added a new family, Eleutherodacytlidae, to the list of frogs known to possess defensive, toxic alkaloids in their skin-the so-called poison frogs [1]. The alkaloids have attracted much attention since they are not synthesized by frogs de novo, but rather are obtained from dietary sources and subsequently sequestered in the frogs skin [2]. These cleptotoxins comprise several pumiliotoxins and other lipid-soluble alkaloids that are known or suspected to be present in the frogs prey, which includes ants, beetles, millipedes and, most notably, oribatid mites [2,3]. Four lineages of phylogenetically unrelated poison frogs that sequester prey alkaloids were previously recognized (Dendrobatidae, Mantellidae, Bufonidae and Myobatrachidae), and the abovementioned miniaturized eleutherodactylid frogs from Cuba [1] represent a fifth.. As with dendrobatids [2], oribatid mites were suspected to be the major dietary source for alkaloids in eleutherodactylid ...

True toads are widespread and are native to every continent except Australia and Antarctica, inhabiting a variety of environments, from arid areas to rainforest. Most lay eggs in paired strings that hatch into tadpoles, although, in the genus Nectophrynoides, the eggs hatch directly into miniature toads.[1]. True toads are toothless and generally warty in appearance. They have a pair of parotoid glands on the back of their heads. These glands contain an alkaloid poison which the toads excrete when stressed. The poison in the glands contains a number of toxins causing different effects. Bufotoxin is a general term. Different animals contain significantly different substances and proportions of substances. Some, like the cane toad Rhinella marina, are more toxic than others. Some psychoactive toads, such as the Colorado River toad Incilius alvarius,[2] have been used recreationally for the effects of their bufotoxin. Male toads possess a Bidders organ. Under the right conditions, the organ ...
Using both the Sagdeev and Korteweg-de Vries (KdV) methods, ion thermal effects on slow mode ion acoustic solitons and double layers are investigated in a plasma with two adiabatic positive ion species. It is found that reducing the gap between the two ion thermal speeds by increasing the relative temperature of the cool ions increases the typical soliton/double layer speeds for all values of the ion-ion density ratio and reduces the range in the density ratio that supports double layers. The effect of increasing the relative cool ion temperature on the soliton/double layer amplitudes depends on the relative densities. For lower values of the ion density ratio, an increase in cool ion temperature leads to a significant decrease in soliton/double layer amplitude, so one may find that solitons of all permissible speeds lie within the range of KdV theory. ...

The non-monoexponential DWI decay at high b-values has been attributed to the multiplicity of water diffusion rates, which may provide the information about the water compartmentation. The common way to compute the diffusion rates is through the multi-exponential analysis. The bi-exponential model assumes two diffusion rates. Considering the multiple length scales in tissues, the distributed exponential model makes no assumption about the number of diffusion rates, and can be empirically described by the stretched exponential model (α-DWI). Those fitting models: bi-exponential and α-DWI have a few parameters, and have been shown to correlate with the pathology. However, it remains difficult to pin down the underlying biophysical mechanisms. In addition, the multi-exponential relation is phenomenological, because each diffusion rate is no longer associated with a mono-exponential decay when diffusion time is long (,30 ms in a clinical DWI). In this study, the distribution of effective ...
Atelopus zeteki, the Panamanian golden frog, is a small, brightly-colored frog. Adult dry forest males measure 35-40 mm in SVL and weigh 3-5 g; adult dry forest females measure 45-55 mm and weigh 4-7 g. Wet forest males and females are larger; adult males measure 39-48 mm in SVL and weigh 8-12 g, while adult females measure 55-63 mm and weigh 10-15 g (Poole 2006). The head is longer than broad, with a pointed, protuberant snout and rounded canthus rostralis (Savage 2002). The pupil is horizontally elliptical (Savage 1972). There is no tympanum, and the ostia pharyngea are slitlike or absent, implying the lack of other middle ear structures such as the auditory ossicle and middle ear cavity (in common with most other species of Atelopus) (Lindquist and Hetherington 1996). However, standard inner ears with well-developed auditory end organs are present (Savage 2002; Lindquist and Hetherington 1996). The body is slim with long limbs, and the upper surface is smooth with minute spicules; when ...
Atelopus onorei is a moderately sized Harlequin frog with male snout-vent lengths ranging from 35.2 mm - 41.3 mm and larger females with a snout-vent length ranges of 41.9 mm - 47.0 mm. Individuals of this species generally have a head that is approximately as long as it is wide, with male head widths ranging from 10.2 - 12.6 mm (an average of 11.6 ± 0.8 mm). The range for head lengths in males is 10.9 - 13.3 mm, the average being 12.2 ± 0.08 mm. Females are again larger with a range in head length being 12.6 - 13.6 mm (an average of 13.1 ± 0.4 mm) and head width ranging from 11.9 - 13.5 mm (an average of 12.4 ± 0.6 mm). The snout tapers to a point and protrudes a little past the lower jaw. A distinct characteristic of this species is that it lacks a tympanum membrane and annulus. Atelopus onorei generally have a smooth texture along their dorsal, chest, belly, and underside of their flanks. The skin on the throat, lateral to their cloaca, and along the flanks is typically rugose. This frog ...
The sounds that male frogs and toads make when calling for mates or vocalizing their territory is another form of identification. In North Carolina, males from several species of frogs and toads begin calling for mates in late winter. These early callers commonly include the Spring Peeper (Frog) and the American Toad. Both of these species can be seasonally heard on the NIEHS campus. The Peeper is usually the first of the frogs and toads to begin calling. Each species has a distinct call that is performed in a chorus with the goal to be heard above the other choir members. The chorus is actually a series of solos with all participants taking turns and singing as loud as possible. As the weather warms through spring, other frog and toad species have their turn at calling.. (Bill Steinmetz is the Environmental Compliance Officer at NIEHS in the Health and Safety Branch.). ...

Several people in a hiking group at Yosemite that included three who were swept away and presumed dead had climbed over a barricade and were in the water about 25 feet from the edge of a waterfall, standing, playing and taking photographs, witnesses told Yosemite rangers.. One of the victims then slipped and fell, the second victim tried to rescue that person, and the third victim tried to save the other two, said Yosemite National Park spokesman Scott Gediman.. The victims were not related, but were friends. About a dozen people were in the hiking group and had spent an hour at the top of Vernal Falls until tragedy struck.. The presumed dead were identified Wednesday as Hormiz David, 22, of Modesto; Ninos Yacoub, 27, of Turlock; and Ramina Badal, 21, of Modesto.. Vernal Falls is marked with warning signs and barricaded off with a metal-bar guardrail that takes some effort to climb over, Gediman said.. ...

A toad is any of a number of species of amphibians in the order Anura characterized by dry, leathery skin (usually brownish-colored), short legs, and wart-like parotoid glands. Description & Taxonomy. The scientific name of Japanese toads is Bufo japonicas Temminck & Schlegel, 1838. Size is about 7-15cm. The color is usually a reddish brown. There are four aliases. The alias isHiki,Gamagaeru,Gama,Ibogaeru and Senjo. Limbs are comparatively short, and the enlarged body moves slowly. The Japanese toads web doesnt develop so much. Other frogs can jump more though than Japanese toad is a little. The mucus of white poisonous like milk is secreted from a lot of Ivo who puts out a strong venom from a big parotoid that exists in back of the head, and exists in the skin, especially the ...

To our knowledge, this study provides the first electrophysiological data on the collecting duct system of an anuran amphibian. We examined the characteristics of K+ transport by the collecting duct system of the toad Bufo bufo. Qualitatively, there seemed to be no difference between K+ transport in cells from collecting tubules and from collecting ducts. Our data indicate that luminal K+ channels would provide a pathway for secretion of K+ from the cell into the lumen.. The collecting duct system of amphibians is a heterocellular epithelium composed of principal and intercalated cells (Møbjerg et al., 1998). In this context it should be noted that the Vbl of collecting duct cells fell into two groups, one being more hyperpolarized than the other. We do not know if this distribution (Fig. 2A) reflects two populations of cells in different functional states, or cells with different transport characteristics, e.g. principal and intercalated cells. In the present study it was not possible to ...

I went to go see if the amphibians would react to the warmth and rain last night. Was hoping to see Spotted Salamanders, toads and frogs too. Started out at Waveny Park in New Canaan at 9:30pm. On the east entrance to the park along the curvy road, I pulled over my truck, turned it off and shut the lights off, and went along walking with my flashlight. Right off the bat....Lots of Spring Peepers, a few Wood Frogs, a couple American Toads hoping across the road to a near vernal pool to mate. Quite a few already crushed by vehicles, including one Spotted Salamander-bummer! Next spot I tried was Mountain Pond area in Danbury. Lots of non direct traveling to hear and see what was along the roads. I drove with windows down, radio off, air off, flashlight in my lap, and digital maps on my iPhone. Would stop when able to get closer looks at the little guys as I travelled. Saw many peepers, toads, and Wood Frogs along the way. Took pictures and scooped them across the road to where they wanted to go ...

Also, I would be alone so I would need to meet people, hopefully ones who could teach me. Or should I take a class? What do I do?

The Australian tree frog has a few other names like Whites tree frog, or simply the green tree frog, but its this last name we like best - the dumpy tree frog, because it is, well, dumpy.

YOSEMITE NATIONAL PARK, Calif. (AP) - In the bird world, they make endangered condors seem almost commonplace.. The unique Great Gray Owls of Yosemite, left to evolve after glacial ice separated them from their plentiful Canadian brethren 30 millennia ago, are both a mystery and concern to the scientists charged with protecting them.. With fewer than 200 in existence in this small pocket of the Sierra Nevada, the slightest disturbances by humans can drive the extremely shy birds from their nests, disrupting sporadic mating cycles that ebb and flow annually depending upon food availability.. So this summer, researchers found a way to abandon their traditional heavy-handed trapping, banding and the blasting of owl calls in favor of the kind of discrete, sophisticated technology used by spies and forensic scientists.. They hope to lessen human influence on this subspecies of owls prized for the potential insights their survival offers into habitat-specific evolution.. Even if it takes only 15 ...

The last person killed in a rockfall at Yosemite was Peter Terbush, a 21-year-old college student from Colorado who was killed when rocks fell from Glacier Point on June 13, 1999.. Standing on the ground, the rock climber was anchoring a climbing partners rope when 525 tons of boulders fell from 1,300 feet above. Terbush did not run away. Instead, he held the rope tightly, saving the life of his friend, Kerry Pyle, who was 60 feet above. Hailed as a hero afterward, Terbush was killed when a chunk of rock hit him in the head.. His family sued the National Park Service for negligence afterward for $10 million, saying that the park should have posted warning signs and may have increased the risk of danger because water from a leaking storage tank at Glacier Point could have affected the rocks stability. A judge dismissed the lawsuit in 2005.. In 2003, a rockfall near Curry Village damaged several cabins and injured four people. About 100 cabins closed afterward. Some were relocated.. There have ...

Football is a sport where the players need to have the tremendous stamina to stay on the playground. Stamina does not refer to having a toned and shaped body. Stamina comes to those people who exercise regularly, eat healthily and stay active. It is important o have all the world-class football equipment with you to better your game, but stamina cannot be replaced. An article on www.bloggingtheboys.com stated that players who stop concentrating on building their stamina often face body fatigue due to the game. Tiredness is obvious, but feeling weak and fatigue all the time indicates that you are not taking appropriate care of your body..

Purpose Given the bone tissue tropism of prostate cancer, conventional imaging modalities poorly identify or quantify metastatic disease. was carried out. Optimal time for imaging post-injection was decided. Results The dose was well tolerated with moderate chills and rigors seen in two patients. The clearance of 89Zr-huJ591 from serum was bi-exponential with biological half-lives of 7 4.5 h (range 1.1C14 h) and 62 13 h (range 51C89 h) for initial rapid and later slow phase. Whole-body biological clearance was 219 48 h (range 153C317 h). The mean whole-body and liver residence time was 78.7 and 25.6 h, respectively. Dosimetric estimates to crucial organs included liver 7.7 1.5 cGy/mCi, renal cortex 3.5 0.4 cGy/mCi, and bone marrow 1.2 0.2 cGy/mCi. Optimal time for patient imaging after injection was 7 1 days.

For all those with ballwinder woes, I wholeheartedly recommend the Strauch ballwinder. Its made here in the USA (here in Virginia, in fact), if buying North American matters to you.. Its not cheap (in the $140 neighborhood), and it looks like the simplest machine on the planet, but it WORKS. Youre supposed to clamp it to a table with the included clamp, but I usually sit my Amish swift and the winder on my hallway floor and sit myself on the stairs.. There are no gears, which is the brilliant part. It uses a stretchy drove band to connect the disc with the crank to the yarn-ball-holding rotating tube. Tube, disc, and base are all wooden and very sturdy. A thick piece of copper wire (non-bendy and sturdy) with a twist/loop is permanently attached as a yarn guide.. With no gears, yarn just doesnt get tangled. It never ejects a ball. Also, I have, no kidding, wound a ONE POUND hank of handdyed worsted weight wool into a SINGLE ball on this winder! I had to hold the guide out just a bit at the ...

Today, the Sonoran Desert Toad just barely makes it into the extreme southwestern tip of New Mexicos bootheel on the east, where the Yaqui River drainage enters New Mexico, but inhabits most of the southern half of Arizona. The only fossil New Mexican record for the area is relatively close to the eastern limits, at U-Bar Cave. A large permanent spring is within several miles of the cave today and Pleistocene Playas Lake occurred to the northwest, both likely presenting suitable habitat.. Fig. 1. Incilius alvarius.

A new semiarboreal species of the Rhinella festae group is described from montane forests of the Cordillera Azul National Park between 1245 and 1280 m a.s.l. in the Cordillera Oriental, San Martín region, northern Peru. The new species is morphologically and genetically compared with members of the Rhinella acrolopha group (former genus Rhamphophryne) and members of the R. festae group. The new species is characterized by its large size (female SVL 47.1-58.3 mm, n = 4), eight presacral vertebrae, fusion of the sacrum and coccyx, long protuberant snout, snout directed slightly anteroventral in lateral view, cranial crests moderately developed, absence of occipital crest, presence of tympanic membrane, dorsolateral rows of small conical tubercles extending from parotoid gland to groin, hands and feet with long digits, fingers basally webbed and toes moderately webbed. Phylogenetically it is a member of the R. festae group which is most closely related to R. chavin and R. yanachaga from Peru.

Western toads are active from January to October, depending on latitude and elevation, and hibernate over the winter.[12] Boreal toads in one Colorado population used natural chambers near a small stream bed. The high water table, constantly flowing stream, and deep winter snow served to maintain the air temperature within the hibernaculum at a point slightly above freezing. Emergence from hibernation followed a few days of warm temperatures that freed the entrance and increased temperatures within the chamber to about 39.2 °F (4.0 °C).[10][13] At low elevations western toads are active at night; at high elevations and in the northern parts of their range they are diurnal.[12] Body temperature of western toads is closely correlated with the substrate temperature. Basking and conduction from the substrate are primary means of increasing body temperature and cooling is achieved by ...
