Who's behind that mask and cape? The Asian leopard cat's Agouti (ASIP) allele likely affects coat colour phenotype in the Bengal cat breed. [PDF]

open access: yes, 2014
Coat colours and patterns are highly variable in cats and are determined mainly by several genes with Mendelian inheritance. A 2-bp deletion in agouti signalling protein (ASIP) is associated with melanism in domestic cats. Bengal cats are hybrids between

Multiple origins of melanism in two species of North American tree squirrel (Sciurus)

open access: yesBMC Evolutionary Biology, 2019
Background While our understanding of the genetic basis of convergent evolution has improved there are still many uncertainties. Here we investigate the repeated evolution of dark colouration (melanism) in eastern fox squirrels (Sciurus niger; hereafter “

Parallel evolution of urban–rural clines in melanism in a widespread mammal

open access: yesScientific Reports, 2022
Urbanization is the dominant trend of global land use change. The replicated nature of environmental change associated with urbanization should drive parallel evolution, yet insight into the repeatability of evolutionary processes in urban areas has been

Orientation to the sun by animals and its interaction with crypsis [PDF]

open access: yes, 2015
1. Orientation with respect to the sun has been observed in a wide range of species and hasgenerally been interpreted in terms of thermoregulation and/or ultraviolet (UV) protection. For countershaded animals, orientation with respect to the sun may also

Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]

open access: yes, 2016
Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.

Phenotypic Expression in the Paper Wasp \u3ci\u3ePolistes Fuscatus\u3c/i\u3e (Hymenoptera: Vespidae) [PDF]

open access: yes, 2017
Quantification of color/color pattern in Polistes fuscatus (Fabricius) revealed that these attributes were the interaction of two antagonistic color sequences; their expression being highly correlated with nest microclimate (relative humidity-temperature)

Significant distribution extension and first verified record of Chiapan Beaded Lizard, Heloderma alvarezi (Bogert & Martin del Campo, 1956) (Squamata, Helodermatidae), in southeastern Guerrero, Mexico [PDF]

open access: yesCheck List, 2021
We document the first verifiable records of Heloderma alvarezi (Bogert & del Campo, 1956) in southeastern Guerrero, Mexico. We recorded seven individuals of H. alvarezi near the village of Cihuapoloya, municipality of Cuautepec.
