Functional and phylogenetic convergence of winter and breeding bird communities in the northeastern US

open access: yesEcography, Volume 2025, Issue 10, October 2025.
Around the world, ecological communities are becoming more similar to one another in a process known as biotic homogenization – an increase in similarity among communities over time. While biotic homogenization has been widely studied among spatial communities, very little attention has been paid to beta diversity between seasonal communities ...

Quantitative Assessment of Bullet Fragments in Viscera of Sheep Carcasses as surrogates for White-Tailed Deer

open access: yesHuman-Wildlife Interactions, 2017
Avian scavengers, such as bald eagles (Haliaeetus leucocephalus), can be exposed to lead through the consumption of spent lead from ammunition in carcasses of animals shot with lead-based projectiles.

Community‐informed and codesigned research to understand the impacts of railways on wildlife

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

Past research and future directions in understanding how birds use their sense of smell

open access: yesIbis, Volume 167, Issue 4, Page 853-881, October 2025.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

Vulnerability of birds to climate change in California's Sierra Nevada

open access: yesAvian Conservation and Ecology, 2014
In a rapidly changing climate, effective bird conservation requires not only reliable information about the current vulnerability of species of conservation concern, but also credible projections of their future vulnerability. Such projections may enable

Anthropogenic impacts on mosquito populations in North America over the past century. [PDF]

open access: yes, 2016
The recent emergence and spread of vector-borne viruses including Zika, chikungunya and dengue has raised concerns that climate change may cause mosquito vectors of these diseases to expand into more temperate regions.

Utilization Probability Map for Migrating Bald Eagles in Northeastern North America: A Tool for Siting Wind Energy Facilities and Other Flight Hazards.

open access: yesPLoS ONE, 2016
Collisions with anthropogenic structures are a significant and well documented source of mortality for avian species worldwide. The bald eagle (Haliaeetus leucocephalus) is known to be vulnerable to collision with wind turbines and federal wind energy ...
