Two new syntopic species of glassfrogs (Amphibia, Centrolenidae, Centrolene) from the southwestern Andes of Ecuador [PDF]
PeerJ, 2023 We describe two new species of glassfrogs of the genus Centrolene living in syntopy at La Enramada, province of Azuay, southwestern Ecuador. They were found in a small creek in montane evergreen forests at 2,900 m elevation.

Characterization of the Leucistic Texas Rat Snake Pantherophis obsoletus
Frontiers in Ecology and Evolution, 2021 Albinism and leucism are phenotypes resulting from impaired melanin pigmentation in the skin and skin appendages. However, melanin pigmentation of eyes remains unaffected in leucism.

Evolution of Endothelin signaling and diversification of adult pigment pattern in Danio fishes. [PDF]
PLoS Genetics, 2018 Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding the genes and cell behaviors underlying the evolution of adult form. Among these species, zebrafish D.

Unmixing octopus camouflage by multispectral mapping of Octopus bimaculoides’ chromatic elements
Nanophotonics, 2021 Cephalopods camouflage abilities arise from highly specialized chromatic elements in their skin, chromatophores, iridophores, and leucophores, that enable them to display complex and rapidly changing color patterns.

Body coloration and mechanisms of colour production in Archelosauria: the case of deirocheline turtles [PDF]
Royal Society Open Science, 2019 Animal body coloration is a complex trait resulting from the interplay of multiple mechanisms. While many studies address the functions of animal coloration, the mechanisms of colour production still remain unknown in most taxa.

Genetic mapping and molecular mechanism behind color variation in the Asian vine snake
Genome Biology, 2023 Background Reptiles exhibit a wide variety of skin colors, which serve essential roles in survival and reproduction. However, the molecular basis of these conspicuous colors remains unresolved.

A new Andean treefrog (Amphibia: Hyloscirtus bogotensis group) from Ecuador: an example of community involvement for conservation [PDF]
PeerJ, 2021 We provide several lines of evidence to delimit a new species of Hyloscirtus and define its phylogenetic position inside the Hyloscirtus bogotensis group.
