Abstract:
Despite the predominance of low-frequency hearing in anuran amphibians, a few frog species have evolved high-frequency communication within certain environmental contexts. Huia cavitympanum is the most remarkable anuran with regard to upper frequency limits; it is the first frog species known to emit exclusively ultrasonic signals. Characteristics of the Distortion Product Otoacoustic Emissions from the amphibian papilla and the basilar papilla were analysed to gain insight into the structures responsible for high-frequency/ultrasound sensitivity. Our results confirm the matching of vocalization spectra and inner ear tuning in this species. Compared to most anurans, H. cavitympanum has a hyperextended hearing range spanning from audible to ultrasonic frequencies, far above the previously established ‘spectral limits’ for the amphibian ear. The exceptional high-frequency sensitivity in the inner ear of H. cavitympanum illustrates the remarkable plasticity of the auditory system and the extent to which evolution can modify a sensory system to adapt it to its environment.

Abstract:
AbstractDeclines in anuran populations worldwide are increasingly creating demands for quick and urgent strategies to maximize efforts to conserve amphibian populations, especially in areas in which few detailed data on diversity, abundance and distribution are available, such as the Cerrado of Central Brazil. We used extent of occurrence of 105 species of Anura (Amphibia) in the Cerrado region to establish a regional system of potential areas that preserves all anuran species in the region, at a macroecological scale. The final network, obtained using a simple "greedy" algorithm based on complementarity, has a total of 10 regions, widely distributed in the biome. These areas were also evaluated in terms of their human demographic parameters (human population size and growth rate). Strong spatial autocorrelation in species richness indicates that alternative systems based on pre-existing conservation units will also be efficient in terms of biodiversity conservation. Although macro-scale approaches are usually coarse, they can provide overall guidelines for conservation and define the focus for more local and effective conservation efforts, which is particularly important when dealing with a taxonomic group such as anurans for which quick and drastic population declines have been reported in many regions of the world.

Abstract:
Infection patterns of the chytrid fungus, Batrachochytrium dendrobatidis, on anuran assemblages in agro-ecosystems from Buenos Aires Province, Argentina. The disease chytridiomycosis, caused by the pathogenic chytrid fungus Batrachochytrium dendrobatidis (Bd), is linked to extinctions and declines of amphibians. Additionally, in the context of amphibian decline, the habitat loss related to agricultural landscapes is likely the single most important human activity affecting lowland amphibian populations. To assess the impact of anthropogenic land use on anuran response to Bd, infection patterns in several ponds from cultivated (CA) and uncultivated areas (UCA) were studied. Four anuran species (Rhinella fernandezae [Bufonidae]; juvenile and adult of Leptodactylus latrans [Leptodactylidae]; and the hylids Hypsiboas pulchellus and Pseudis minuta) were monitored and tissue samples were collected for Bd diagnosis and quantification. All species tested positive for Bd, but anurans inhabiting the UCA were twice more likely to be infected than those in the CA. Prevalence and infection level were significantly higher in the UCA, suggesting that vulnerability to Bd is associated with land use in agro-ecosystems. At the assemblage-level, the infection patterns also differed among species, and those with aquatic habitats (L. latrans and P. minuta) had high prevalence and infection levels of Bd. Juvenile stages of L. latrans had higher prevalence and infection level than adults in both study areas. This work contributes to our understanding of anthropogenic effects on host-pathogen relationships, particularly on the effect of Bd on anuran assemblages under different levels of agricultural impact.

Abstract:
AbstractThis constitutes the first study of anuran fauna composition of an artificial permanent water reservoir, in a semiarid ecosystem of San Luis. Species richness, relative abundance, spatial distribution and pattern of summer activity were estimated in the anuran community of the Embalse La Florida, an artificial water reservoir in the semiarid central region of the sierras of San Luis, Argentina. This reservoir represents one of the few sources of water available for reproduction and early development of amphibian species in the zone. We identified anurans using call surveys during two summers at fifteen sites, belonging to four zones around the shorelines of the reservoir. Eight amphibian species (Rhinella arenarum, Melanophryniscus stelzneri, Leptodactylus bufonius, Leptodactylus mystacinus, Odontophrynus americanus, Odontophrynus occidentalis, Pleurodema tucumanum and Hypsiboas cordobae) were recorded at the shores of the embalse. The highest species richness (seven) was detected in the preserve located on the north shore. Species richness analyzed by month or survey was not correlated with weather variables. The highest relative abundance of anurans was detected at the highly modified campsites area, which may provide stable food and refugia. Relative abundance of all anuran species was positively correlated with precipitation. This permanent water reservoir may act as an important site of amphibian fauna concentration, which is important to monitor and preserve.

Abstract:
Although it is generally assumed that agriculture negatively influences amphibian populations, few studies on the effects of agricultural cultivations on neotropical anuran have been conducted. As a contribution to the knowledge about anuran in agriculture, the present study sought to identify the anuran species present in three different agrossystems. We used data from anurans captured in pitfall traps initially proposed for a survey of harvestmen fauna in three agrossystems (corn, soybean, and rubber tree). Four anuran species found in the pitfall traps belong to two Families: Leptodactylidae: Leptodactulus fuscus and L. mystacinus; and Leiuperidae: Eupemphix nattereri and Physalaemus cuvieri. In corn plantation, four species and 30 individuals were captured; in rubber trees, four species and 11 individuals; and in soybeans plantation, tree species and eight individuals. Our results show that anurans are present in agrossystems, mainly the generalist anuran species.

Abstract:
The amphibian chytrid fungus (Batrachochytrium dendrobatidis) is a widespread, cosmopolitan pathogen largely affecting free-living amphibian populations. So far there are no published studies for the presence of B. dendrobatidis in Greece. In this preliminary study we sampled 59 metamorphosed anurans from four Greek wetlands. Five samples were positive for the fungus by real-time PCR. B. dendrobatidis was detected in three species (Bufo viridis, Pelophylax epeiroticus, Pelophylax ridibundus) but not in endangered endemic Karpathos water frogs (Pelophylax cerigensis). This is the first report of the amphibian chytrid fungus (Batrachochytrium dendrobatidis) in free-living anuran populations from Greece.

Abstract:
ABSTRACTAmphibian distribution patterns are known to be influenced by habitat diversity at breeding sites. Thus, breeding sites variability and how such variability influences anuran diversity is important. Here, we examine which characteristics at breeding sites are most influential on anuran diversity in grasslands associated with Araucaria forest, southern Brazil, especially in places at risk due to anthropic activities. We evaluate the associations between habitat heterogeneity and anuran species diversity in nine body of water from September 2008 to March 2010, in 12 field campaigns in which 16 species of anurans were found. Of the seven habitat descriptors we examined, water depth, pond surface area and distance to the nearest forest fragment explained 81% of total species diversity. Water depth, margin vegetation type, surface area and distance to the next body of water explained between 31-74% of the variance in abundance of nine of the 16 species. Thus, maintenance of body of water, of the vegetation along the water edge and natural forest fragments in the grasslands, along with fire control (used to renovation of pasture), are fundamentally important for the maintenance of anuran species diversity through the conservation of their breeding sites.

Abstract:
The mesencephalic tectum plays a prominent role in integrating both visual and multimodal sensory information essential for normal behavior in amphibians. Activity in the mesencephalic tectum is thought to be modulated by the influence of distinct neurochemical inputs, including the catecholaminergic and the cholinergic systems. In the present study, we have investigated the distribution and the origin of the catecholaminergic innervation of the mesencephalic tectum in two amphibian species, the anuran Rana perezi and the urodele Pleurodeles waltl. Immunohistochemistry for dopamine and two enzymes required for the synthesis of catecholamines, tyrosine hydroxylase (TH) and dopamine β-hydroxylase (DBH), revealed a complex pattern of catecholaminergic (CA) innervation in the anuran and urodele mesencephalic tectum. Dopaminergic fibers were primarily present in deep tectal layers, whereas noradrenergic (DBH immunoreactive) fibers predominated in superficial layers. Catecholaminergic cell bodies were never observed within the tectum. To determine the origin of this innervation, applications of retrograde tracers into the optic tectum were combined with immunohistochemistry for TH. Results from these experiments demonstrate that dopaminergic neurons in the suprachiasmatic and juxtacommissural nuclei (in Rana) or in the nucleus pretectalis (in Pleurodeles), together with noradrenergic cells of the locus coeruleus, are the sources of CA input to the amphibian mesencephalic tectum. The present results suggest that similar CA modulatory inputs are present in the mesecencephalic tectum of both anurans and urodeles.

Abstract:
The identification of anuran amphibians is still a challenge in megadiverse assemblages. In the Neotropics, the Atlantic Forest harbors more than 600 anuran species, and many studies in this ecoregion report anuran assemblages surpassing 30 species. Taxonomic keys facilitate the identification of biological diversity, however only a few are available for anuran assemblages in the Atlantic Forest. Herein we present an identification key for 40 anuran species distributed across 20 genera and nine families, occurring in the Environmental Protection Area of Catolé and Fernão Velho, northeastern Atlantic Forest. Thirty-five morphological characteristics were used in the key, all of which can be easily observed in living and museum specimens. This pioneer study provides the first identification key for an amphibian assemblage in the northeastern Atlantic Forest and this baseline information acts as the starting point for the development of evolutionary and ecological research in this conservation unit.

Abstract:
The decline in amphibian populations is been recorded all around the world. Brazil has an important role in its conservation, since it has the greatest diversity of the group. The Atlantic Forest is the Brazilian biome that comprises the higher diversity and endemism of amphibians, however it is also the habitat of almost all endangered frogs. The northern portion of the biome is known as the Biogeographic Sub-region (BSR) Pernambuco, which includes the forest fragments of the north of the São Francisco River, except for the " Brejos de altitude". This region contains a very specific fauna and an unique genetic diversity, but only 1% of its remains are protected in the form of conservation areas. Conservation actions are urgently needed, however the lack of information is an obstacle for developing action plans in the region. In this context, in the first chapter, an macroecological approach was applied for the conservation of endemic and threatened frogs in the Northern Atlantic Forest. Thus, ten endemic species and one endangered were registered in the study area. The results suggest that the forest fragments found in the north of the state of Alagoas and in the southern state of Pernambuco, Brazil, are extremely important for maintaining the biodiversity, even in the face of climate change. The second chapter presents the description of the reproductive biology of the only endangered species the BSR Pernambuco, Agalychnis granulosa.

Evidências apontam para o declínio nas populações de anfíbios em diversas regiões do globo, e o Brasil tem um papel importante na conservação desse táxon, já que é o país que possui a maior diversidade do grupo. A Mata Atlântica é o ecossistema que abriga a maior parcela da fauna de anfíbios e o maior número de espécies endêmicas do país. No entanto, também é o habitat de quase todas as espécies de anuros ameaçados de extinção. A porção setentrional do bioma é conhecida como Sub-Região Biogeográfica (SBR) Pernambuco, e reúne os fragmentos florestais situados ao norte do Rio São Francisco, excetuando-se os brejos de altitudes. Atualmente sabe-se que essa região abrange uma fauna bastante específica e uma diversidade genética única, porém apenas 1% de seus remanescentes está protegido sob a forma de unidades de conservação. Ações conservacionistas são necessárias imediatamente, todavia a escassez de informação é um entrave para elaboração de planos de ação na região. Nesse contexto, no primeiro capítulo, foi realizada uma abordagem macroecológica para a conservação de anuros endêmicos e ameaçados na Mata Atlântica Setentrional. Assim, foram registradas dez espécies endêmicas, e uma ameaçada de extinção. Os resultados indicam que os fragmentos localizados ao norte do bioma da Mata Atlântica no Estado de Alagoas e na porção sul no Estado de Pernambuco, Brasil, são de extrema importância para manutenção da biodiversidade, mesmo diante das mudanças climáticas. No segundo capítulo, é apresentada a descrição da reprodução da única espécie ameaçada de extinção da SBR Pernambuco, Agalychnis granulosa.

Abstract:
Understanding wetland responses to human perturbations is essential to the effective management of Florida's surface and ground water resources. Southwest Florida Water Management District (SWFWMD) Rules (Chapter 40D-2.301(c) FAC) prohibit adverse environmental effects to wetlands, fish and wildlife caused by groundwater withdrawal. Numerous studies have documented the responses of biological attributes across taxa and regions to human disturbance. Biological assessment can provide information about ecological condition. Based on long-term monitoring conducted by the SWFWMD, the anthropogenic changes observed on the Starkey Wellfield are attributed to groundwater withdrawal. Biological indicators are species, species assemblages, or communities whose presence, abundance, and condition are indicative of a particular set of environmental conditions. Monitoring early indicators of ecosystem stress may shorten response time by shifting attention to the relatively quick response of sensitive species. Species used to assess biological condition should be abundant and tractable elements of the system that provide an early, diagnosis. Regulatory requirements within 40D-2 F.A.C. dictate an extensive analysis be conducted twice yearly on wetlands within all wellfields. This quantitative analysis provides information on the wetland plant community through the collection of eighteen categorized vegetative and physical variables. Because of the size of the area in which monitoring is required and the large number of wetlands, a rapid qualitative monitoring method was developed using vegetation and physical variables to classify wetlands into one of three categories based on their perceived health. Wetland plants have many characteristics suited to assessments of biological condition including their diversity, taxonomy, distribution, relative immobility, well developed sampling protocols, and, for herbaceous species, their moderate sensitivity to disturbance (U.S. EPA 2002, Doherty et al. 2000). Because amphibians occupy both aquatic and terrestrial habitats in their life history, have physiological adaptations and specific microhabitat requirements, they are considered to be extremely sensitive to environmental perturbations and excellent barometers of the health of the aquatic and terrestrial habitats in which they reside (Vitt et al. 1990, Wake 1998, Blaustein 1994, Blaustein et al. 1994). The purpose of my study was to 1) compare a qualitative method of wetland vegetation monitoring to a quantitative method, 2) document the reproductive success of anurans, and 3) compare anuran reproductive success to the vegetation monitoring results on the J. B. Starkey Wellfield (SWF). The results are published in chapters, with each chapter addressing one of the topics stated above. The results show a rapid, qualitative measure of wetland health is useful for the determination of severely affected wetlands. The anuran reproductive success reflected similar results. The results show that wetlands can be categorized based solely on amphibian reproductive success variables. The anuran categorization, qualitative vegetative categorization, and quantitative vegetative categorization overlap on the high and low success wetlands. The low degree of overlap observed in the intermediate category could be attributed to fish predation in a wetland otherwise suited for amphibian reproduction, natural variability in the two years of anuran data collected or lag time inherent in vegetative monitoring. Strong correlative evidence suggests hydroperiod regulates anuran reproductive success on the J. B. Starkey Wellfield. The average length of inundation was correlated with the number of tadpoles captured per unit effort and the number of tadpole species captured per year (R=0.73, p<.01; R=0.70, p<.05). The average Julian date of inundation at which breeding attempts stopped and no tadpoles were observed was weeks within the published breeding season for many species. I detected a correlation between the number of species calling in each wetland and the number of tadpole species captured per year (R=0.87, p<.001) suggesting call censuses may be used at this site to estimate anuran reproductive success if enough well-timed observations are made. These findings will allow resource managers and regulators to evaluate and possibly refine land management practices, including existing monitoring methods, and water policy to meet the needs of resident amphibians at the J.B. Starkey Wellfield.

Abstract:
Hair cell trauma from aminoglycosides, which may lead to permanent loss of hair cells in mammals, was studied physiologically in frogs by measuring an auditory evoked potential (AEP) in Rana pipiens. The AEP was evaluated in order to measure threshold shift (TS) and recovery from TS after the administration of the aminoglycoside antibiotic, gentamicin. To obtain an AEP, chronic electrodes were implanted into the cranium near the cochlear nucleus. The frogs were then exposed to frequency-specific narrow band ~clicks" which included a single period 1 kHz sinewave, and a computer synthesized high frequency and low frequency click. Amphibians have two hearing organs, the amphibian and basilar papillae, sensitive to low (150-1500) and high (1500-2000) frequencies, respectively. The low (AP) and high (BP) frequency clicks were created to stimulate specifically the corresponding papillae. After normal thresholds were recorded for each frog, gentamicin sulfate, 200 μM, 300 μM, or 400 μM, was injected bilaterally into the otic capsules. Thresholds were recorded until the TS had disappeared, allowing the threshold recovery period to be measured. The injections of 200 μM yielded a 10 dB change in one animal and no change in two others. The injection of 300 μM into 10 frogs and 400 μM into 20 frogs yielded at least a 10 dB change in 60% and 93% of the frogs, respectively, with the concentration of 400 μM producing threshold shifts of 20 dB. Thus, the threshold shifts were dose-dependent. Recovery times varied between six and fourteen days. No apparent differences between thresholds for the high frequency click, low frequency click and sinewave clicks were observed.

A total of nine amphibian species (representing five families) are known from São Tomé and Príncipe islands, all of which are endemic. No amphibians have been reported from Annobón. Taxonomic research on this group of animals began in the second half of the nineteenth century with subsequent refinement following the advent of molecular techniques. The presence of several amphibians from distinct evolutionary lineages is unexpected for oceanic islands and has motivated several biogeographic studies to reconstruct the evolutionary histories of these enigmatic species. Yet, the continental source for many of the islands’ amphibians remains unknown. The amphibians of São Tomé and Príncipe also exhibit intriguing phenotypic diversity for addressing long-standing hypotheses in evolutionary biology, including body size evolution and gigantism on islands, intraspecific variation and interspecific divergence in coloration, and reproductive and dietary niche partitioning. Recent studies have confirmed the presence of the fungal pathogen Batrachochytrium dendrobatidis in amphibian communities on both São Tomé and Príncipe, but it is unclear whether this pathogen is negatively impacting local populations. Most of the Gulf of Guinea oceanic island endemic amphibians are incredibly abundant and widespread, occurring in primary forest, secondary forest, and agricultural habitats across the islands. Three anuran species (Hyperolius thomensis, Leptopelis palmatus, Ptychadena newtoni) have more limited distributions and/or more specialized ecologies; consequently, additional land-use change poses a threat to the long-term persistence of these taxa.

Abstract:
This work is based on helminthological data of amphibians, collected since 2013 until 2020, in the Republic of Moldova. The investigations on anura amphibians were conducted in the laboratory of Parazitology and Helminthology of the Institute of Zoology. One of the most common parasitic diseases in ruminants is fasciolosis, caused by the trematode Fasciola hepatica species. The results of parasitological research showed that adult cattle were infected with fascioles in 66.4% of cases, and young cattle - in 46.1% of cases. This is largely due to the grazing of animals of different species and ages in limited areas.The presence of the trematode species Haplometra cylindracea was established in 78% of cases in the amphibians in the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis). The results of laboratory helminthological investigations have shown that the relationships between the Fasciola hepatica miracidium and the Haplometra cylindracea miracidium are antagonistic. Amphibians of the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis) infested with Haplometra cylindracea tremateda may play an important role in the prophylaxis of fasciolosis.

Abstract:
Introdução: Phyllomedusa bahiana é uma espécie de anuro (Amphibia) com distribuição restrita ao estado da Bahia. Como os demais representantes da família Phyllomedusidae, a espécie é popularmente conhecida como perereca-macaco e tanto seu status de conservação como sua biologia reprodutiva continuam escassos de informações, dificultando estratégias de conservação. Objetivos: O presente estudo tem como objetivo geral descrever o comportamento reprodutivo de Phyllomedusa bahiana por meio dos seguintes objetivos específicos: classificar o padrão de reprodução; descrever os sítios de canto; verificar dimorfismo sexual em tamanho e caracterizar comportamentos reprodutivos. Material e métodos: A área de estudo foi um corpo d’água semipermanente do município de Vitória da Conquista, Bahia. A região é marcada pela transição Floresta Estacional Semidecídua (Mata Atlântica) – Caatinga. Para descrição do comportamento reprodutivo foi utilizado o método Animal-focal. Além de caracterização ambiental da área, mensurou-se altura e distância da margem dos poleiros utilizados e comprimento rostro-cloacal (CRC) dos indivíduos. Resultados: Foi observado atividade de vocalização da espécie durante os seis meses de estudo, apresentando, portanto, um padrão reprodutivo prolongado. A ocupação de sítio de canto da espécie foi exclusivamente galhos de arbustos com altura média ocupada de 0,98 metros. 85,7% dos indivíduos vocalizaram em arbustos acima do corpo d’água. Foi observado fêmeas se locomovendo lentamente sobre os galhos com o macho sobre o dorso em um amplexo do tipo axilar. A fêmea é perceptivelmente maior e obteve um CRC médio de 86mm, enquanto o CRC médio do macho foi de 64mm. Conclusão: Os aspectos reprodutivos de P. bahiana se assemelham aos de outras espécies de mesmo gênero (e.g. P. burmeisteri), entretanto, sua faixa de distribuição difere. Portanto, trabalhos que investiguem aspectos ambientais e climáticos que atuam sobre a biologia da espécie podem contribuir para o maior conhecimento de sua História Natural.

Abstract:
Structural and biomechanical parameters of Edible Frog, Pelophylax esculentus (Linnaeus, 1758), limb bones, namely, mass, linear dimensions, parameters of the shaft ’s cross-sectional shape (cross-sectional area, moments of inertia, radiuses of inertia) were investigated. Some coeffi cients were also estimated: diameters ratio (df/ds), cross-sectional index (ik), principal moments of inertia ratio (Imax/Imin). Coeffi cients of variation of linear dimensions (11.9–20.0 %) and relative bone mass (22–35 %) were established. Moments of inertia of various bones are more variable (CV = 41.67–56.35 %) in relation to radii of inertia (CV = 9.68–14.67 %). Shaft ’s cross-sectional shape is invariable in all cases. However, there is high individual variability of structural and biomechanical parameters of P. esculentus limb bones. Variability of parameters was limited by the certain range.We suggest the presence of stable norm in bone structure. Stylopodium bones have the primary biomechanical function among the elements of limb skeleton, because their parameters most clearly responsiveto changes in body mass.

Abstract:
The management and recovery of threatened and endangered amphibians on Department of Defense (DoD) lands relies on an understanding of their distribution and abundance. Fortunately, most anuran species can be surveyed acoustically using vocalizations during the breeding season. This work demonstrated the use of subsurface passive acoustic monitoring (SPAM) to survey for rare underwater-calling, at-risk anuran species on DoD installations. We evaluated the performance of SPAM relative to traditional passive acoustic monitoring (PAM) (microphone) and human manual calling survey (MCS) methods. Results showed that SPAM outperformed PAM and MCS in validation experiments where calls were generated underwater; SPAM was less successful than PAM and MCS in the field demonstration. Most leopard frog calls were apparently produced in air despite previous reports of extensive underwater-calling behavior. This project highlights how acoustic information can help address a data gap in the ecology of at-risk species, which can help refine future survey methodology and management efforts. Ultimately, the utility of SPAM for underwater-calling species will depend on the focal species, the landscape where it occurs, and technological considerations available to the surveyor. SPAM is more expensive than traditional methods but, in some situations, may be the only way to effectively detect species.
