Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

open access: yesIntegrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change

open access: yesIntegrative Zoology, EarlyView.
Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

Stratified Bed Conditions Impact on Scour Development at Engineering Structures

open access: yes
River flow contraction by engineering structures (intakes, embankment, abutments, spurs, guide banks) to flow leads to flow pattern modification, concentration of streamliners, sharp drop in water level, local increase in velocity, and development of ...

A Lightweight Deep Neural Network for Individual Leopard Identification: Supporting Movement Ecology in the Taihang Mountains of Henan

open access: yesIntegrative Zoology, EarlyView.
We developed LeoNet, a lightweight deep learning model for leopard individual identification. It achieved 97.42% accuracy and was robust to age‐related pattern changes and unfamiliar individuals. Applied to camera‐trap data from the Taihang Mountains, LeoNet identified 41 wild North China leopards and generated individual‐level records to support ...

Spectacle and Spy Stories: The 1954 Royal Commission on Espionage

open access: yesAustralian Journal of Politics &History, EarlyView.
ABSTRACT The Menzies government's 1954 royal commission, established to investigate Soviet espionage in Australia, is well known as the backdrop to the Labor Party split. It saw opposition leader H.V. Evatt's demise and ushered in an almost 20‐year period of Liberal Party governance.
