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

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.

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 one or two of four types of specialized mucous glands that presumably secrete pheromones delivered to females during cephalic amplexus. The discovery of these glands adds a new dimension to studies of poison frog reproductive biology, which have investigated acoustic,

Expression patterns of melanin-related genes are linked to crypsis and conspicuousness in a pumpkin toadlet. [PDF]
Mol EcolAbstract Colour signals play pivotal roles in different communication systems, and the evolution of these characters has been associated with behavioural ecology, integumentary production processes and perceptual mechanisms of the species involved. Here, we present the first insight into the molecular and histological basis of skin colour polymorphism ...

Pigments, Chromatophore Structure, and Gene Expression Underlying Colour Polytypy of a Panamanian Poison Frog. [PDF]
Mol EcolABSTRACT Colour polytypism represents an example of phenotypic diversification shaped by genetic divergence and ecological pressures. Poison frogs of the genus Oophaga (Dendrobatidae) are highly polytypic in coloration, making them an ideal system for investigating the genetic and physiological basis of colour variation.

Body size but not warning signal luminance influences predation risk in recently metamorphosed poison frogs. [PDF]
Ecol Evol, 2015 During early development many aposematic species have bright and conspicuous warning appearance, but have yet to acquire chemical defenses, a phenotypic state which presumably makes them vulnerable to predation. We deployed artificial prey of green‐and‐black poison frogs in the field, and show that rates of attack by bird predators were significantly ...

Investigating signal modalities of aposematism in a poison frog
Journal of Evolutionary Biology, Volume 36, Issue 7, Page 1003-1009, July 2023., 2023 In this manuscript, we asked if predators avoid poison frogs by their sense of smell alone. We found that experienced predators can indeed avoid poison by smell alone, indicating the importance of examining other modalities of potential communication in aposematic vertebrates.

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.
