Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Integrating remote sensing, expert knowledge, and field data can accurately identify and prioritise ecosystem shifts in semi-arid savannas

Environmental Research Communications
Semi-arid savanna ecosystems are increasingly vulnerable to climate change and anthropogenic disturbances, leading to significant changes in woody cover and structure.

Ranging of older male elephants introduced to an existing small population without older males: Pilanesberg National Park

Koedoe: African Protected Area Conservation and Science, 2004
The African elephant Loxodonta africana is one of the key components of African savanna. Not only do they play a crucial role in the ecosystem (Dublin et al. 1990; Van de Vijver et al. 1999), but they also provide one of the integral parts of sustainable

Carbon and nitrogen balances for six shrublands across Europe [PDF]

, 2009
Shrublands constitute significant and important parts of European landscapes providing a large number of important ecosystem services. Biogeochemical cycles in these ecosystems have gained little attention relative to forests and grassland systems, but ...

Putting Rodents at the Center of One Health Programs: A Narrative Synthesis

Integrative Zoology, EarlyView.
Rodents link human, animal, and environmental health across diverse ecosystems. Rodent diversity underpins both zoonotic disease risk and ecosystem function. Environmental change reshapes rodent communities and spillover dynamics. Rodents act as reservoirs, amplifiers, and sentinels of emerging pathogens.

The ecological effects of grazing by the White Rhino (Ceratotherium simum simum) at a landscape scale [PDF]

, 2005
In this thesis I generated hypotheses concerning the top down effect of grazing ungulates on grass communities and fire behavior from work done within grazing exclosures in Hluhluwe iMfolozi Park.

Tree Squirrels Selectively Disperse High‐Quality Acorns Away From Tree Trunks

Integrative Zoology, EarlyView.
Acorn quality and squirrel feeding behavior significantly structured spatial dispersal patterns of two Californian oak species. Non‐infested acorns were preferentially selected for embryo excision and dispersed farther than infested ones. Acorns were fully consumed near tree trunks, signaling rapid feeding in safe refuges, whereas non‐eaten, partially ...
