Posture does not matter! Paw usage and grasping paw preference in a small-bodied rooting quadrupedal mammal. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Recent results in birds, marsupials, rodents and nonhuman primates suggest that phylogeny and ecological factors such as body size, diet and postural habit of a species influence limb usage and the direction and strength of limb laterality ...

Analysis of mitochondrial control region DNA variation in New Zealand's brushtail possums (Trichosurus vulpecula) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University [PDF]

open access: yes, 2001
Brushtail possums (Trichosurus vulpecula) were first introduced from Australia to New Zealand in 1858 to establish a fur industry. Currently numbering more than 65 million, they are recognised as the most important mammalian pest in New Zealand, because ...

Genomic Analysis and Population Divergence Driven by Geographic Isolation in Neotetracus sinensis

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We generated the first chromosome‐level reference genome for Neotetracus sinensis and resequenced populations from the Gaoligong and Wuliang Mountains to investigate divergence across the Hengduan “sky‐island” landscape. Genomic data reveal strong population structure with negligible gene flow and parallel demographic histories shaped by Pleistocene ...

Beavers on Ice: Factors Influencing Emergence Phenology in Boreal Canada

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
Climate‐driven changes in ice phenology influence the timing of spring emergence of a non‐hibernating ice‐bound mammal, the North American beaver. ABSTRACT The influence of climate change on emergence phenology of hibernating mammals in northern latitudes is receiving increased attention, yet for freshwater semi‐aquatic mammals such as beavers, which ...

Characteristics of the tree shrew gut virome

open access: yesPLOS ONE, 2019
The tree shrew (Tupaia belangeri) has been proposed as an alternative laboratory animal to primates in biomedical research in recent years. However, characteristics of the tree shrew gut virome remain unclear. In this study, the metagenomic analysis method was used to identify the features of gut virome from fecal samples of this animal. Results showed

Pathological and genetic aspects of spontaneous mammary gland tumor in Tupaia belangeri (tree shrew).

open access: yesPLoS ONE, 2020
Mammary gland cancer is the most common cancer occurring in women globally. Incidences of this cancer in Japan are on the increase. Annually, more than 70,000 new cases are recorded in Japan and about 1.7 million in the world.

Adaptive Genetic Variation in Black‐and‐White Snub‐Nosed Monkeys (Rhinopithecus bieti): Low Diversity and the Role of Balancing Selection

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We investigated the adaptive genetic diversity within a population of Rhinopithecus bieti using amplicon sequencing. From 47 individuals, we identified 16 MHC class I sequences, revealing a low level of adaptive genetic variation. Although evidence for balancing selection, including positive selection and trans‐species polymorphism, was observed, these

A decade of studies at Loch Fleet, Galloway (Scotland): A catchment liming project and restoration of a brown trout fishery [PDF]

open access: yes, 1995
Loch Fleet is a small upland lake in the hills of Galloway in southwest Scotland. In the 1970s the waters of the loch became more acidic and a brown trout fishery failed. This account summarises an experimental project, the "Loch Fleet Project" initiated
