All the species of Physalaemus Fitzinger, 1826 karyotyped up until now have been classified as 2n = 22. The species of the P. cuvieri group analyzed by C-banding present a block of heterochromatin in the interstitial region of the short arm of pair 5. Physalaemus cicada Bokermann, 1966 has been considered to be a member of the P. cuvieri species group, although its interspecific phylogenetic relationships remain unknown. The PcP190 satellite DNA has been mapped on the chromosomes of most of the species of the P. cuvieri group. For two species, P. cicada and P. kroyeri (Reinhardt & Lütken, 1862), however, only the chromosome number and morphology are known. Given this, the objective of the present study was to analyze the chromosomes of P. cicada and P. kroyeri, primarily by C-banding and PcP190 mapping. The results indicate that P. kroyeri and P. cicada have similar karyotypes, which were typical of Physalaemus. In both species, the NORs are located on the long arm of pair 8, and the C-banding

Bransfords Litter Frog, Eleutherodactylus bransfordii Picture. Found in low and middle elevation wet forests; found on the ground or hidden below the leaf litter.
This thesis describes a hybrid zone between two taxa of toads, Bombina bombina and Bombina variegata in north eastern Croatia. The two taxa can be distinguished at four diagnostic enzyme loci. Clines at these loci are highly concordant; there is strong disequilibrium and substantial heterozygote. Both linkage disequilibrium and heterozygote deficit are asymmetric, being greater on the bombina side than on the variegata side. Different habitats are identified across the zone and a strong association with the genotype of the populations sampled from them, is found. This relationship is consistent across the hybrid zone. The cline is best described by a model which incorporates both a difference in gene frequency between habitats and a width which varies from place to place. Mark recapture studies show extensive movement, which implies that the association between habitat and genotype is due to a habitat preference. Translocation experiments suggest that there is adaptation to the habitats. A ...

Previous cytogenetic and phylogenetic analyses showed a high variability in the frog taxa Physalaemus cuvieri and Physalaemus ephippifer and suggested the presence of undescribed diversity in this species complex. Here, by 1) adding specimens from the Brazilian Amazon region, 2) employing sequence-based species delimitation approaches, and 3) including RADseq-style markers, we demonstrate that the diversity in the P. cuvieri-P. ephippifer species complex is even greater than previously suspected. Specimens from Viruá and Western Pará, located at the Guiana Amazonian area of endemism, were recovered as distinct from all previously identified lineages by the phylogenetic analyses based on mitochondrial DNA and RAD markers, a PCA from RAD data, and cytogenetic analysis. The sequence-based species delimitation analyses supported the recognition of one or two undescribed species among these Amazonian specimens and also supported the recognition of at least three other species in the P. cuvieri-P.
Hyla arborea schelkownikowi is one of the leaf frog species inhabiting the southern territories of Russia and the former USSR. This frog species is a member of the Hylidae Rafinesque, 1815 batrachians family. The present study deals with the previously uninvestigated peptidome of the Hyla arborea schelkownikowi skin secretion. Nano-electrospray ionization Fourier transform mass spectrometry (nanoESI-FTMS) of the skin secretion, in the intact form and after acetylation, was selected as the general method of analysis. Electron-capture dissociation (ECD) and collision-induced dissociation (CID) fragmentation were both employed, while de novo sequencing was performed by manual interpretation of the MS data. The suppression of the cyclization of b-ions in the mass spectrometer by the acetylation reaction proved to be very efficient for the de novo sequencing of short peptides. Ten skin peptides were found and all of them, except for bradykinin, had not previously been reported. Six of the peptides ...

Most American green tree frog females breed once per year, but some have multiple clutches in a single mating season.[1] In a Florida population, advertisement calls of males were documented between March and September and pairs in amplexus were observed between April and August. In the Florida population, the average number of offspring in a single clutch was observed to be about 400 eggs.[1] Eggs take between four and 14 days to hatch, with an average of five days.[1] According to the Animal Diversity Web at the University of Michigan Museum of Zoology, Female size was positively correlated with clutch size, but after the initial clutch, the number of eggs nearly always decreased.[1] Breeding is known to be strongly influenced by day length, temperature, and precipitation.[1] While the relative influence of these factors is not well understood, it is known as the frogs generally breed following rainfall, and males call more frequently as temperature and day length increase.[1] Some ...
Coloured scanning electron micrograph (SEM) Coqui frog toe pad (Eleutherodactylus coqui). The coqui, also called the little frog in Puerto Rico, has only a minute tail when it is born, which quickly disappears. Its length ranges between 15mm-80mm and the colour of the coqui varies considerably. green, brown and yellowish, sometimes having touches of different colours. This genus has no inter-digital membrane, which could indicate that they are not adapted to swim. All coquis have disks or pads on the tips of their toes, to help them adhere to surfaces, like moistened leaves.

One persistent issue of the taxonomy of Microhylidae has been the inclusion of scaphiophrynines (Scaphiophryne and Pseudohemisus); the group has been alternatively included in Ranidae or Microhylidae (see review in Wassersug, 1984). The ambiguity was based on the description of tadpoles of two Malagasy species by Angel (1931), which were referred to Pseudohemisus verrucosus and P. longimanus; these tadpoles had beaks and denticles. However, these larvae were shown to belong to ranid species (Blommers-Schlösser, personal communication in Wassersug [1984]). Otherwise, the monophyly of Microhylidae has not been questioned.. The Type 2 larva of Orton (1953, 1957) was generally considered diagnostic of Microhylidae, but larvae of scaphiophrynines, as for many microhylids, remained unknown. However, the description of the tadpole of Pseudohemisus granulosum (Blommers-Schlösser, 1975; Wassersug, 1984, 1989) provided an intermediate suite of characters between the Type 2 and Type 4 tadpoles, and drew ...
Among the Amphibia there are numerous examples of the suppression to a varying extent of a larval stage in the life-history. In such instances the animal is freed by various means from the necessity of passing its early phases of development in open water. This evolutionary trend has nowhere proceeded further than in the Anuran genus Eleutherodactylus, which is distributed through the Caribbean and the adjacent mainlands. In Eleutherodactylus, development is direct and wholly embryonic, and many larval features have been suppressed.. In 1871 was published the first description of a West Indian frog which laid eggs in air, and from which young frogs with fully formed limbs were hatched (Bello y Espinosa, 1871). Since that time some twenty papers have been published on the embryology of different species of the genus, mainly in recent years by Dr. W. Gardner Lynn and his collaborators.. ...
Coloured scanning electron micrograph (SEM) Frog blood in liver blood vessel (coqui, Eleutherodactylus coqui). Frogs have nucleated red blood cells. In the amphibian circulatory system blood accumulates oxygen in the lungs and is then returned to the heart before being pumped through the rest of the circulatory system. Mixing between oxygenated and deoxygenated blood occurs as blood returning to the heart from the lungs is mixed with incoming blood from the body. Frogs depend on cutaneous respiration for their oxygen supply. In this process oxygen from the air is drawn into a frogs body by the blood vessels that lie close to the skin. Waste gas and carbon dioxide are also released the same way. Magnification: x240 when shortest axis printed at 25 millimetres. - Stock Image C032/4707

Hyla andersonii, only about 1-3 inches (25-76 mm) long, is one of the smaller species of tree frogs. Members of the species are predominantly green, with wide, dark stripes. They often have spotted, orange-gold markings on the hidden surfaces of their legs and tend to have large toe pads. The key to distinguishing the Pine Barrens tree frog from the similar-appearing American green tree frog (H. cinerea) is the white-bordered lavender stripe on each side of the body in the Pine Barrens tree frog. H. cinerea has only a white stripe in this location. ...

Examination of serial sections of the oesophagus and stomach of Rana esculenta and Bombina variegata revealed that oesophageal peptic glands were only present in Rana, where gastric glandular cells performed only one functional role, represented by HCl production. In contrast, in Bombina the gastric glands were mainly of oxynticopeptic cells with dual oxyntic and peptic roles, reflected morphologically by distinct different areas of their cytoplasm. During activity of the oxynticopeptic cells cytoplasmic differences were reduced because the tubular profiles, carrying HCl, and zymogen granules emerged at the cell apex.

Within Anura, direct development involves ontogenetic changes of the biphasic ancestral pattern. The recent partitioning of the genus Eleutherodactylus, along with the proposition of the unranked taxon Terrarana, has renewed an interest to the morphological and ecological diversity among direct-developing frogs. The morphological changes during embryonic development of Oreobates barituensis is similar to those of other Neotropical direct-developing species, including the reduction or absence of several larval and embryonic characters (e.g., external gills and adhesive glands), heterochronic changes (e.g., early developing limbs and late persistence of ciliated epidermal cells), and the appearance of new structures (e.g., egg tooth). The tail achieves an extraordinary peramorphic development (encloses the entire embryo), and the location of its expanded part is interpreted as a heterotopic change resulting in a novel trait. An enveloping tail with apparently non-heterotopic fins, combined with the

Spermatogonia _ three stages of differentiation were distinguished. The primordial spermatogonia or primordial germ cells are the most voluminous cells of the spermatogenetic lineage, whose nuclei are irregular and with a multilobular aspect. They present chromatinic granu-lations, beside a single, eccentric nucleolus. In general, they are very close to the locular wall, and are associate to the Sertoli cells which still have aspect of follicular cells and the nucleus is falciform. It is also common that these sperma-togonia be isolated or joined in small groups, but this do not characterize germ cysts. From mitotic divisions, the primary (I) and the secondary (II) spermatogonia are originated. The secondary ones are smaller, more irregular, and they were identified due to the nuclear compactation degree. The spermatogonia I are organized as cellular cysts with a irregular aspect and hard delimitation, they are located near the locular wall. The spermatogonia II suffer some alterations, which ...
For the purpose of reproduction most amphibians require fresh water although some lay their eggs on land and have developed various means of keeping them moist. A few (e.g. Fejervarya raja) can inhabit brackish water, but there are no true marine amphibians.[66] There are reports, however, of particular amphibian populations unexpectedly invading marine waters. Such was the case with the Black Sea invasion of the natural hybrid Pelophylax esculentus reported in 2010.[67]. Several hundred frog species in adaptive radiations (e.g., Eleutherodactylus, the Pacific Platymantis, the Australo-Papuan microhylids, and many other tropical frogs), however, do not need any water for breeding in the wild. They reproduce via direct development, an ecological and evolutionary adaptation that has allowed them to be completely independent from free-standing water. Almost all of these frogs live in wet tropical rainforests and their eggs hatch directly into miniature versions of the adult, passing through the ...
Recently a new Mathematical Biology program for undergraduate students at the University of Louisiana was developed. In this talk, the new courses that are being developed as part of this program will be presented and the research projects that the undergraduate students participate in will be discussed. In particular, as part of what we hope will be a long-term monitoring survey, a population of the green tree frog (Hyla cinerea) was followed from June through October 2004 and 2005 at the National Wetlands Research Center (NWRC) and the National Marine Fisheries Service complex (NMFC). Due to urbanization, the frog population is relatively isolated. H. cinerea were collected once a week, measured, and marked. Data from the captures were used to estimate the population size of the frogs at the NWRC/NMFC complex. The results indicate that the data period can be split into two time periods: the first during and the second after the breeding season. During the breeding season we found our ...

This family includes only two genera, Barbourula and Bombina. Barbourula occurs in the Philippine Islands (Barbourula busuangensis) and Borneo (Barbourula kalimantanensis). The approximately eight species of Bombina are found in Europe, western Asia, China, Vietnam, and Korea.. Bombina are warty, aquatic toads, and tend to be gregarious. The vocal behavior of some Bombina is unusual in that the call is produced during inhalation rather than exhalation as in other frogs. They lay pigmented eggs in ponds. The tadpoles have beaks, two upper and three lower rows of denticles, and a median spiracle (typical Orton Type 3). Species of Bombina have bright red or yellow mottling on the venter. The German word Unke means toad. Bombina exhibit an unken reflex when bothered. The animal will arch its back and limbs to expose the bright belly, and may turn over on its back. This acts as a warning to predators. Not surprisingly, the skin toxins of Bombina are distasteful.. Barbourula are not as brightly ...
Several representatives of this family of small, diurnal frogs are famous for their bright skin coloration and associated toxins. There are from four to seven genera in this family, and less than 200 species. Distribution is restricted to humid tropical America, from Nicaragua to Brazil, with the greatest diversity in northwestern South America.. Dendrobatids are the most brightly colored of any anuran group. Although the large genus Colostethus is drab-colored and non-toxic, the derived aposematically colored dendrobatids (members of the genera Dendrobates, Phyllobates, and their kin) have skin toxins comprised of lipophilic alkaloids, some of which can easily kill a human if ingested. The only other anuran group exhibiting both bright colors and lipophilic alkaloids are the unrelated Mantellas (Rhacophoridae). Dendrobatids are small (20-40 mm snout-vent length, though the putative basal species, the nocturnal Aromobates, attains lengths of 62 mm). Synapomorphies of this family include the ...
Background. Frogs are generalist predators of a wide range of typically small prey items. But descriptions of dietary items regularly include other anurans, such that frogs are considered to be among the most important of anuran predators. However, the only existing hypothesis for the inclusion of anurans in the diet of post-metamorphic frogs postulates that it happens more often in bigger frogs. Moreover, this hypothesis has yet to be tested.Methods. We reviewed the literature on frog diet in order to test the size hypothesis and determine whether there are other putative explanations for anurans in the diet of post-metamorphic frogs. In addition to size, we recorded the habitat, the number of other sympatric anuran species, and whether or not the population was invasive. We controlled for taxonomic bias by including the superfamily in our analysis.Results. Around one fifth of the 355 records included anurans as dietary items of populations studied, suggesting that frogs eating anurans is not unusual.

The Red backed Poison Frog (Ranitomeya reticulata) is a species of frog belonging to the family Dendrobatidae. Its an arboreal insectivorous species, and is the second most poisonous species in the genus, after R. variabilis. Like many species of small poisonous frogs native to South America, its grouped with the poison dart frogs, and is a moderately toxic species, containing poison that is capable of causing serious injury to humans, and death in animals such as chickens. This frog is native to Peru and Ecuador.. Its toxins are utilized as the frogs natural defense mechanisms, making them inedible to many, if not most, of the predators in its natural area. To advertise its poison and to further reduce the risk of injury, the red backed poison frog displays its brilliant warning colors, especially its red-orange back, for which it is named. Like all dendrobatids, it doesnt manufacture the poison itself, but rather is theorized to take the toxins from the ants, mites, and beetles on which it ...

From frogs to humans, selecting a mate is complicated. Females of many species judge suitors based on many indicators of health or parenting potential. But it can be difficult for males to produce multiple signals that demonstrate these qualities simultaneously. In a study of Copes grey tree frogs, a team of University of Minnesota researchers discovered that females prefer males whose calls reflect the ability to multitask effectively. In this species (Hyla chrysoscelis), males produce trilled mating calls that consist of a string of pulses. Typical calls can range in duration from 20-40 pulses per call and occur at the rate of between 5-15 calls per minute. Males face a trade-off between call duration and call rate, but females preferred calls that are longer and more frequent, which is no simple task. The findings were published in the August 2013 issue of Animal Behaviour. Its kind of like singing and dancing at the same time, says Dr. Jessica Ward, a postdoctoral researcher who is ...
For thousands of years, Nature has been considered to be essential for human beings for the treatment of their diseases. Amphibians are an important component of the Animal Kingdom and have played a significant role in sourcing many active compounds and some therapeutics. In the course of this research, genomic and proteomic techniques have been used to investigate the bioactive peptides from the skin secretions of four American amphibian species: the Central American red-eyed leaf frog, Agalychnis callidryas~ the South American orange-legged leaf frog, Phyllomedusa hypochondrialis, Rohdes leaf frog, Phyllomedusa rohdei and the Giant Mexican leaf frog Pachymedusa dacnicolor. The synthetic peptides all exhibited significant biological activities. Medusins were a novel family of antimicrobial peptides found in all species investigated and all possessed a broad-spectrum of antibiotic activity. Phylloseptins were found to be active against both planktonic bacteria and those within biofilms. ...
Males are smaller than females, with adult males reaching approximately 2 inches in length and adult females reaching 3 inches in length. Juveniles are brownish and change to bright green as the mature. Belly is light blue or cream colored, legs are blue and feet are red - orange. Eyes are bright red in adults. Toes have suction cups to help them adhere themselves to the undersides of leaves. They are excellent climbers and also can swim.. ...
The quartet of straw pollsters were among the first to leave their marks on the ballot paper ahead of this Thursdays General Election.. The guinea pigs were offered a list of candidates which included Ms G Raff, Mrs C Lyon and Mr R Madillo representing a range of parties like the Liberal Meerkats, the Green Tree Frog party and the Boa Constrictor party. Longleat keeper Rebecca Earner said: They were all extremely keen to get inside the Polling Station; although this may have had something to do with the chopped beans and carrots we had placed inside.. ...
Now, researchers have found a source for potentially revolutionary new drugs in frog skin, ones that may be effective in fighting antibiotic-resistant infections. Particular compounds found in frog skin secretions function as effective bacteriostats and bacteriocides. However, their pharmaceutical development has been hampered by the fact that they are too easily disabled by the human bodys immune system.. But chemists were able to alter some of the frog compounds to make them both more effective at targeting antibiotic-resistant bacteria and longer-lasting inside the bloodstream. Thus, the researchers are now collecting and screening frog skin secretions from around the world with renewed hope.. A news release from the American Chemical Society summarized the research presented at their national meeting, which was held in Boston August 22-26.2 In a cursory statement about how frogs acquired this advanced chemical technology, Michael Conlon, a chemist at the United Arab Emirates University, ...
Female frogs and toads tend to be larger than males. Males attract them with song, then cling to them (sometimes using special clasping pads that develop during the breeding season) and fertilize their eggs as they shed them into water. In most frogs and toads eggs and seminal fluids are emitted at the same time; fertilized eggs are then deposited singly or in clumps or strings.. The eggs hatch into polliwogs, round-bellied, long-tailed larvae that, like those of salamanders, have gills on the outside of their body. In frogs and toads, but not in salamanders, these external gills are soon covered with skin. So most of the tadpoles you catch will have no visible gills.. Eventually, in one of natures most dramatic transformations, the tadpole changes into a frog or a toad, a tailless terrestrial creature with long hind limbs and lungs instead of gills. How long tadpoles stay as tadpoles vary with both species and temperature. Desert-dwelling spadefoot toads may spend a mere two weeks at this ...
