Structure and evolution of the sexually dimorphic integumentary swelling on the hands of dendrobatid poison frogs and their relatives (Amphibia: Anura: Dendrobatoidea). [PDF]
J Anat, 2022 The hands of adult males of many dendrobatid poison frogs and their relatives possess swelling formed by glandular tissue hypothesized to secrete courtship pheromones delivered to the female during cephalic amplexus.

QUANTITY DISCRIMINATION IN POISON DART FROG (Dendrobates auratus) [PDF]
, 2020 Many studies have argued that quantity discrimination is a shared ability across vertebrates that is inherited from a common ancestor or is a result of convergent evolution.

Toxicon, 2003 A transmission electron-microscope study has been performed on larval and juvenile skin of the Central American arrow-frog Dendrobates auratus to investigate early secretory processes and maturational changes in the serous (poison) glands. Poison biosynthesis involves the endoplasmic reticulum (both smooth and rough types), as well as Golgi stacks ...

Pool choice in a vertical landscape: Tadpole-rearing site flexibility in phytotelm-breeding frogs. [PDF]
Ecol Evol, 2021 Certain Neotropical frogs use plant‐based pools of water as nurseries for their young. This study covers the biological and chemical factors influencing pool choice across the vertical gradient in three different species. Abstract Many species of Neotropical frogs have evolved to deposit their tadpoles in small water bodies inside plant structures ...

Patterns of infection, origins, and transmission of ranaviruses among the ectothermic vertebrates of Asia. [PDF]
Ecol Evol, 2021 Ranaviral infections are becoming frequent, severe, and widespread, causing mortality in native biodiversity and cultured species in Asia. Ranaviruses have a broad host range and are transmitted through live animal trade. Ranaviral disease is predominantly a summer disease, which may spread unhindered with global warming. The controlling of the disease

INFLUENCIA DE LA ESTRUCTURA AMBIENTAL SOBRE LA DENSIDAD POBLACIONAL DE DENDROBATES AURATUS, EN EL BOSQUE TROPICAL FRAGMENTADO EN BOCAS DEL TORO [PDF]
Centros: Revista Científica UniversitariaThe present study determined the association between the population density of Dendrobates auratus with environmental and structure factors in five transects in a fragmented tropical forest ecosystem in Bocas del Toro. For this, 25 samplings were carried

Analysis of morphological attributes as a driver of trade in poison dart frogs. [PDF]
Conserv BiolAbstract The unsustainable use of wildlife is a threat to biodiversity on a global scale, and the insatiable demand is driven by the attributes of the species, their parts, and derivatives. However, not all species are equally valued; certain attributes command a higher price. One example is the exotic pet trade in amphibians and reptiles.
