The study of amphibian conservation is urgent and broad. In order to understand and act in the preservation of this taxon, we must deepen the studies in the different facets of the amphibian biology, from the most basic questions, such as taxonomy, behavior, natural history, ecology and evolution, but also to investigate the aspects more directly related to their threats, such as environm…
The equipment will be used in quantitative PCR, allowing analysis of 384 simultaneos samples. It will be used in virtually all subprojects of the Temático grant. Besides chytrid, iIt also alows experiments with Ranavirus. Finally, it will be used for genotyping the strains collected during the project. (AU)
The chytrid fungus Batrachochytrium dendrobatidis (Bd) is recognized worldwide as one of the main causative agents of amphibian population declines and extinctions over the last 50 years. The same is valid for the Brazilian Atlantic Forest, where a portion of the amphibian species may have been extinct by this fungus. Although Bd is already widespread in the biome, new die off events may …
The chytrid fungus, Batrachochytrium dendrobatidis (Bd), is an important infectious agent, globally related to amphibian population declines. With this fungus as a central theme, increasing our comprehension of the disease status in Brazil, in 2011 we were awarded a grant by a joint call from FAPESP and NSF. That grant expected to build the foundation of an international collaboration bet…

The heart of anurans has five chambers: venous sinus, left and right atria, ventricle, and arterial cone. However, in a recent study, it was observed that individuals of Brachycephalus rotenbergae and B. pitanga have a heart with a reduced atrial septum, thus, with one less chamber. Furthermore, it was noted that they lack a visible carotid body, which is found in the carotid artery and p…
The first extinctions resulting from anthropogenic activities occurred around the 18th century, a period coinciding with the onset of modern taxonomy. In fact, species have been erased from the tree of life before we became aware of their existence. These unknown species are not explicitly incorporated into conservation strategies, with their inclusion only taking place after the publicat…
A particular feature of the reproduction of some organisms is parental care, considered an evolutionary advantage for increasing offspring survival. Parental care behaviors have been described in insects, arachnids, fish, amphibians, birds, reptiles, and mammals. Despite being better known in groups such as birds and mammals, parental care in amphibians presents a wide variety of behavior…

Amphibians are the most threatened animal group today. Among the main causes of decline and extinction are epidemics of infectious diseases, such as chytridiomycosis, a disease caused by the fungus Batrachochytrium dendrobatidis (Bd), which is associated with water bodies. However, cases of individuals of direct development species with high Bd loads have been reported. The process by the…
Emerging infectious diseases are amongst the main threats to the world's biodiversity, with the fungus Batrachochytrium dendrobatidis (Bd) and the virus Ranavirus (Rv) being considered as major factors to amphibian declines. Both pathogens are transmitted through water or direct contact with infected individuals, casing their dispersion to be extremely effective. Although there are report…

Hearing is one of the essential components of acoustic communication in anurans. However, it remains relatively unexplored when compared to acoustic emissions. Over 700 Brazilian species of anurans have had their advertisement calls described, whereas studies on hearing are limited to four out of the over 1,200 known species in Brazil. The auditory system of anurans comprises the inner ea…
The consortium of symbiotic microorganisms recruited by vertebrate hosts and their metabolic products (the microbiome) are known to aid in host health. The amphibian skin microbiome represents an important line of defense against a variety of pathogens, including the waterborne fungal pathogen that causes chytridiomycosis, Batrachochytrium dendrobatidis (Bd). However, interactions between…
Invasive wildlife on islands pose major risks via competition, disease transmission and direct predation on local fauna on a global scale. Among these potential impacts, the transmission of pathogens and disruption of trophic networks are quite common. This problem can be even intensified when the island did not naturally have a taxonomic group that invaded it with several species. This i…
