Abstract:
... The genus Proceratophrys currently comprises 40 species, of which five are distributed within the Caatinga domain and associated phytophysiognomies along northeastern Brazil. During field surveys at high altitudinal sites in Boqueirão da Onça region, northern Bahia state, we collected individuals of Proceratophrys that could not be assigned to any species currently known to occur within the Caatin ...

Anura; females; fish; males; research
Abstract:
... A wide range of chemicals have been identified as endocrine disrupting chemicals (EDCs) in vertebrate species. Most studies of EDCs have focused on exposure of both male and female adults to these chemicals; however, there is clear evidence that EDCs have dramatic effects when mature or developing gametes are exposed, and consequently are associated with in multigenerational and transgenerational ...

Abstract:
... Anurans are a highly diverse amphibian order with a biphasic lifestyle. The larva, better known as tadpole, and the adult frog of one species typically occupy different habitats and exploit different resources. Therefore, both are subject of largely independent selection and are able to evolve stage-specific adaptations. Among others, the musculoskeletal features of the larval and adult head of an ...

Abstract:
... Deforestation leads to changes in the landscape, which can isolate and decrease the size of populations affecting their structure and genetic variability. Additionally, it can increase the frequency of chromosomal damage due to exposure to genotoxic agents present in the environment. Among vertebrates, amphibians are the most threatened taxonomic group, especially forest-specialist species. Our wo ...

Abstract:
... Anurans (frogs and toads) expelled urine when handled and it could provide insights into their physiological status. However, storage, preservation and transportation are often challenging. The study aimed to standardize and validate a field method for short-term storage and preserve of anuran urine samples using Whatman filter papers. To examine the efficacy of storage conditions and type of pape ...

Abstract:
... For 80 years, there were no sightings of the Andean frog, Telmatobius halli, due to the ambiguity with which its type locality was described (“warm spring near Ollagüe”, northern Chile). The type specimens were collected during the International High Altitude Expedition to Chile (IHAEC) in 1935 and were subsequently described in 1938. In 2018 and 2020, two studies independently reported the redisc ...

Abstract:
... Anurans that breed in rivers and cascade streams need to deal with the influence of the low-frequency water flow noise that could interfere with their acoustic communication. To overcome that, some species display visual signals or emit high-pitched calls. However, there is a constraint related to body size [snout-vent length (SVL)] that limits the anurans' calling frequency range. Thus, to evalua ...

Abstract:
... Agriculture has been identified as one of the largest contributors to the current global biodiversity crisis. Amphibians are declining worldwide, and the loss of habitat and water contamination related to agricultural land uses have been suggested as the main drivers of this phenomenon. In central Argentina, the Pampean Region combines the highest rates of grassland replacement of South America, t ...

Abstract:
... AIM: To test the importance of evolutionary and biogeographical processes in shaping the assembly of local frog communities in two adjacent regions (hereafter, coastal and inland regions) with different historical signatures. We asked two main questions: (1) why does the coastal region harbour more frog species than the inland region? and (2) how do these processes affect the spatial variation in ...

Abstract:
... There is great heterogeneity in parasite communities among hosts, understanding the nature and drivers of such variations is still a great scientific quest. Here, we analyse the variation in parasite communities by addressing the following questions: (i) What is the beta-diversity component (nestedness or turnover) that most contributes to beta diversity in parasite communities among anuran specie ...

Abstract:
... Temporal scale in animal communities is often associated with seasonality, despite the large variation in species activity during a diel cycle. A gap thus remains in understanding the dynamics of short‐term activity in animal communities. Here we assessed calling activity of tropical anurans and addressed how species composition varied during night activity in assemblages along gradients of local ...

Abstract:
... This paper is a survey of the parasite diversity, prevalence and infection intensity in anurans in diverse ecological settings in West Africa. The settings included natural habitats (rainforests, freshwater creeks, Guinea and Sudan savannas), monoculture plantations (cocoa, cotton and oil palm), urbanized and urbanizing rainforest biotopes and polluted environments due to oil industry activities. ...

Abstract:
... Telmatobius chusmisensis was described from the Tarapacá Region, in the Puna of northern Chile. The lack of information on the species led to its classification as Data Deficient. There has been no information published on its biology or ecology since its original description in 2006. Here, we provide information on its habitat, density, diet, and threats. The habitat of the species is restricted ...

Abstract:
... The ongoing decline in anuran populations is linked primarily to the effects of stressor agents such as pathogens, pesticides, alterations of natural landscapes, and the introduction of exotic species. Most studies that have evaluated the effects of these stressors have focused on a single component, which is the opposite of the reality of most natural environments, where anuran populations tend t ...

... We extend by 300 m the known upper elevational range of the Marsupial frog, Gastrotheca marsupiata (Dumeril & Bibron, 1841), to 4,660 m a.s.l. This record makes G. marsupiata the highest occurring frog in its genus, which is already characterized by high-elevation distributions. We suggest that this record may represent a case of climate-induced range shifting and discuss this record in the contex ...
