Fecal Glucocorticoid and Androgen Metabolites in Eastern Gray Kangaroos (Macropus giganteus) Following Environmental Relocation

Zoo Biology, EarlyView.
Fecal glucocorticoid (GCM) and androgen metabolite (AM) concentrations were monitored for 3 months following the relocation of three eastern gray kangaroos (Macropus giganteus) between zoological facilities. Both metabolites showed high concentrations during the early postrelocation period, followed by a rapid decline and stabilization, suggesting ...

Seasonal Gut Microbiome Variation Associated With Both Climate and Wildlife Tourism in Asian Elephants (Elephas maximus)

Integrative Zoology, EarlyView.
We provide an early description of the gut microbiome of wild, free‐ranging Asian elephants (Elephas maximus). Using 16S rRNA gene amplicon data from 123 fecal samples collected across 6 months in two Sri Lankan national parks, we found that gut microbiome composition varied significantly by sampling month and, to a lesser extent, by park.

The MacBrain Resource Center (MBRC) rhesus macaque postnatal brain histology datasets: Enabling new discoveries through NHP tissue and digital data Repositories

Journal of Anatomy, EarlyView.
The MacBrain Resource Center (MBRC) postnatal rhesus macaque brain histology datasets are organized into Collections that promote cost‐effective de novo research. This article provides examples from Collections 5, 6, and 7 and describes the histo‐ and immunohistochemical (IHC) processing of materials for Collection 6.

Chromosome Evolution in New World Monkeys (Platyrrhini) [PDF]

, 2012
During the last decades, New World monkey (NWM, Platyrrhini, Anthropoideae) comparative cytogenetics has shed light on many fundamental aspects of genome organisation and evolution in this fascinating, but also highly endangered group of neotropical ...

Short-Term Relocation Stress-Induced Hematological and Immunological Changes in Saimiri boliviensis boliviensis

Journal of Immunology Research, 2021
Nonhuman primates are frequently transported to a new location or temporarily relocated within their colony. Both transportation and relocation expose animals to new environments, causing them to undergo a stress response (before adapting).

From quantity to quality: the evolution of forest restoration in the United Kingdom

Restoration Ecology, EarlyView.
Abstract Introduction Over the past century, forest cover in the United Kingdom has increased threefold. However, the pathways, achievements, and shortcomings of this expansion remain underexplored. Objectives This study analyses the drivers, implementation, and legacies of forest restoration in the United Kingdom before and after 1990, which is when ...

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Colour versus quantity as cues in reverse-reward-competent squirrel monkeys (Saimiri sciureus)

, 2008
To assess the relative salience of colour and quantity cues, squirrel monkeys previously trained to reach for the smaller of two quantities of food in a reverse-reward contingency task received colour discrimination training.

Sociability Under Anthropogenic Change: From Individual Behaviour to Population‐Level Consequences

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Our review synthesises empirical and theoretical research on how anthropogenic environmental change reshapes animal social behaviour from individuals to populations. We use sociability as an individual‐level lens, distinguishing context‐dependent expression from repeatable interindividual differences and linking both to social relationships, network ...

Arboreal and Terrestrial Frugivore Vertebrate Assemblage Diversity and Composition Vary With Disturbance Histories in Guianan Forests

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study examined the impact of human disturbances on arboreal and terrestrial fruit‐consuming vertebrate assemblages across three tropical forest sites in French Guiana. While species richness remained consistent across sites, results revealed significant variations in visitation rates and a shift in dominant species.
