Comparative histomorphometric and transcriptomic analysis reveals potential genetic determinants of pelage variation between hairy and coarse-woolly sheep [PDF]

open access: yesBMC Genomics
Background The unique pelage composition and developmental pattern endow hairy sheep with superior heat tolerance and minimized wool-shearing needs, compared with coarse-woolly sheep.

Sexual dichromatism in the fur of a bat: An exploration of color differences and potential signaling functions [PDF]

open access: yesEcology and Evolution
Sex differences in body color (i.e., sexual dichromatism) are rare in bats and, more broadly, in mammals. The eastern red bat (Lasiurus borealis) is a common tree‐roosting bat that occupies much of North America and has long been described as sexually ...

Pelage variation and morphometrics of closely related Callithrix marmoset species and their hybrids [PDF]

open access: yesBMC Ecology and Evolution
Background Hybrids are expected to show greater phenotypic variation than their parental species, yet how hybrid phenotype expression varies with genetic distances in closely-related parental species remains surprisingly understudied.

Photoperiodic influences on ultradian rhythms of male Siberian hamsters. [PDF]

open access: yes, 2012
Seasonal changes in mammalian physiology and behavior are proximately controlled by the annual variation in day length. Long summer and short winter day lengths markedly alter the amplitude of endogenous circadian rhythms and may affect ultradian ...

Total mercury in small mammals from forest ecosystems (nearby Cherepovets, Vologda region) [PDF]

open access: yesE3S Web of Conferences, 2023
The aim of the research is to determine the total mercury (THg) in small mammals in forest ecosystems at a distance of 3 – 8 km from the boundaries of the industrial site of PJSC Severstal near Cherepovets, Vologda region. THg in the pelage and organs of

Roosting ecology and the evolution of pelage markings in bats. [PDF]

open access: yesPLoS ONE, 2011
Multiple lineages of bats have evolved striking facial and body pelage makings, including spots, stripes and countershading. Although researchers have hypothesized that these markings mainly evolved for crypsis, this idea has never been tested in a ...

Ecological Drivers of Eastern Fox Squirrel Pelage Polymorphism

open access: yesFrontiers in Ecology and Evolution, 2020
The color patterns of an animal’s pelage, feather, or skin serve a variety of adaptive functions; importantly, one function is concealment through background matching.

Diásporas y nomadismos literarios: las escrituras contemporáneas de una República dominicana en movimiento

open access: yesILCEA, 2021
The history of Dominican literature is deeply marked by the geographical movements of its writers. Diaspora authors express, in different ways, a floating relationship with spaces (geographical and textual), and an acute awareness of the complexity of ...

Ghost rodents: Albinism in Australian rodent species

open access: yesEcology and Evolution, 2023
While almost half of all mammal species are rodents, records of albinism in free‐ranging rodents are very rare. Australia has a large and diverse assemblage of native rodent species, but there are no records of free‐ranging albino rodents in the ...

Taxonomic status of Tamarinus imperator subgrisescens (Lönnberg, 1940) (Cebidae, Callitrichinae) [PDF]

open access: yesPapéis Avulsos de Zoologia, 2023
The emperor tamarin, Tamarinus imperator, is composed of two subspecies, the nominal type, T. i. imperator, distributed between the Acre and Purus Rivers, whose range is limited between the Brazilian state of Acre and Peru are unbounded, and T.
