Exceptional Visual‐Opsin Coexpression and Phenotypic Diversity in Outer‐Retinal Photoreceptors of Caenophidian Snakes

open access: yesJournal of Comparative Neurology, Volume 533, Issue 10, October 2025.
In snakes, profound differences in retinal architecture are observed between diurnal and nocturnal species. Additionally, in the rod‐dominated retinas of nocturnal snakes, coexpression of the cone opsins SWS1 and LWS in individual cones is common, while rhodopsin (RH1) is restricted to typical rods.

The spectral transmission of ocular media suggests ultraviolet sensitivity is widespread among mammals [PDF]

open access: yes, 2014
Although ultraviolet (UV) sensitivity is widespread among animals it is considered rare in mammals, being restricted to the few species that have a visual pigment maximally sensitive (λmax) below 400 nm.

Variation in Small Mammal Species Composition and the Occurrence of Parasitic Mites in Two Landscapes in a Scrub Typhus Endemic Region of Western Yunnan Province, China

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Yunnan Province, the most serious scrub typhus endemic areas in China, provides abundant ecological resources that sustain parasite and host populations. The distribution of vector‐borne diseases is driven by interactions between hosts, vectors and the environment, revealing critical ecological dynamics.

Individual strategies of aggressive and non-aggressive male mice in encounters with trained aggressive residents [PDF]

open access: yes, 1992
To determine whether individual differences in offensive behaviour are related to differences in defensive behaviour, the responses of male wild house mice, Mus domesticus, of an aggressive and a non-aggressive line to defeat by physically stronger ...

Molecular Epidemiology and Genetic Diversity of Orientia tsutsugamushi From Patients and Small Mammals in Xiangyun County, Yunnan Province, China

open access: yesVeterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Scrub typhus is caused by Orientia tsutsugamushi (OT). In this study, the detection rates of OT in patients and small mammals were 28.13% (18/64) and 13.98% (13/93), respectively. Nine full‐length 56‐kDa TSA genes were identified, comprising four distinct genotypes: Karp‐like (n = 3), Kato‐like (n = 3), Gilliam (n = 2), and TA763 (n = 1). Recombination

Genomic analysis reveals hidden biodiversity within colugos, the sister group to primates [PDF]

open access: yes, 2016
Colugos are among the most poorly studied mammals despite their centrality to resolving supraordinal primate relationships. Two described species of these gliding mammals are the sole living members of the order Dermoptera, distributed throughout ...

Mammal Species Composition and Activity Patterns Shift While Richness Remains Constant Across Elevational Gradients in Western Sarawak, Borneo

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
We examined how mid‐ to large‐bodied mammal communities vary along elevational gradients in northwestern Borneo using camera trap data from six protected areas. Although species richness remained constant across elevations, species composition and activity patterns shifted, with some taxa more common at low or high elevations. These findings underscore

High Ambient Temperatures Are Associated With Reduced Foraging Capacity in an Equatorial Mammal, the Banded Mongoose (Mungos mungo)

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
Our study investigated behavioural thermoregulation in a population of wild banded mongooses found on the equator living under narrow thermal ranges and so potentially vulnerable to even small increases in temperature. We collected fine‐scale behavioural and environmental data and found evidence of behavioural thermoregulation, with individuals ...

Detection and genome characterization of two novel papillomaviruses and a novel polyomavirus in tree shrew (Tupaia belangeri chinensis) in China

open access: yesVirology Journal, 2019
Background Papillomaviruses (PVs) and polyomaviruses (PyVs) infect diverse vertebrates including human and cause a broad spectrum of outcomes from asymptomatic infection to severe disease.

Gustatory responses in primates to the sweetener aspartame and their phylogenetic implications [PDF]

open access: yes, 2017
Two-bottle preference tests have been applied to 70 (sub-) species of the order of Primates and, for comparison, to the tree shrew (Tupaia belangeri) to determine their responses to aspartame (APM), the first known sweet-tasting dipeptide which has to ...
