Phylogenetic and Functional Originality Shape Species Positions in Flea–Mammal Networks Across Biogeographic Realms

open access: yesIntegrative Zoology, EarlyView.
The relationship between the position of a flea species in the networks and its functional originality was found to be consistently positive in all realms, independently of which originality index was used. ABSTRACT We investigated the relationships between a species’ network position (measured as the combined normalized degree, species strength, and ...

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

open access: yesIntegrative 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.

From Data to Knowledge to Wisdom: Lessons Learned From the Vancouver Rat Project

open access: yesIntegrative Zoology, EarlyView.
A synthesis of 15 years of research conducted by the Vancouver Rat Project revealed that: (1) Pathogen ecology within rat colonies is the result of complex interactions among rats, pathogens, and vectors. (2) Local and global population structures influence rat and pathogen ecology.

Drivers of Mouse Plagues: Exceptional Rainfall Following Prolonged Drought Triggers Mouse Plagues in Southeastern Australia

open access: yesIntegrative Zoology, EarlyView.
This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...

Anticoagulant Rodenticides Contribute to a Decline in an Urban Carnivore

open access: yesAnimal Conservation, EarlyView.
Anticoagulant rodenticides (ARs) have been shown to negatively affect carnivores globally and are closely tied to human activity and development. We examined drivers of annual survival in bobcats persisting on a residentially developed barrier island over 16 years.
