Climate‐related drivers of migratory bird health in the south‐central USA

Biological Reviews, Volume 100, Issue 3, Page 1272-1293, June 2025.
ABSTRACT Migratory birds are species of concern that play important ecological roles while also supporting recreational opportunities for the hunting and birdwatching public. Direct and indirect effects of climate variability, extremes, and change on migratory bird health manifest at the individual, population, species, and community levels.

Breeding bird response to adaptive multi‐paddock and continuous grazing practices in Southeastern United States

Ecosphere, Volume 15, Issue 12, December 2024.
Abstract Grassland bird populations are declining steeply, reflecting the degradation and loss of native grassland habitats. To assess how grazing management affects declining grassland bird populations, we compared breeding avifaunal communities in adaptive multi‐paddock (AMP) grazed and continuously grazed (CG) pastures in the Southeastern United ...

Stock‐specific spatial overlap among seabird predators and Columbia River juvenile Chinook Salmon suggests a mechanism for predation during early marine residence

Marine and Coastal Fisheries, Volume 16, Issue 6, December 2024.
Abstract Objective Because predation is thought to be the primary source of natural mortality for juvenile salmon first entering the ocean, we sought to identify regions where, on average, stock‐specific spatial overlap between the distribution of threatened and endangered juvenile Chinook Salmon Oncorhynchus tshawytscha and abundant fish‐eating ...

Conflicting perspectives on ecosystem conservation in a cultivated floodplain: The role of science and the challenge of pluralism in decision‐making in Lac Saint‐Pierre (Quebec, Canada)

Environmental Policy and Governance, Volume 34, Issue 5, Page 476-489, October 2024.
Abstract By generating and explaining facts, science holds an important role in environmental policy decision‐making. However, scientific knowledge is often framed as objective and neutral in policy debates, which can be challenged by stakeholders who have a different view of the issue.

Diet and Effects of Environmental Stressors on the Altricial Nestlings of Double-Crested Cormorants (Phalacrocorax Auritus) [PDF]

, 2014
Double-crested cormorants (Phalacrocorax auritus) are a common species of altricial waterbird found across much of North America. As a piscivorous colonial waterbird, cormorants are often persecuted due to perceived impacts on fisheries.

Correcting for measurement errors in a long‐term aerial survey with auxiliary photographic data

Ecosphere, Volume 15, Issue 8, August 2024.
Abstract Long‐term, large‐scale monitoring of wildlife populations is an integral part of conservation research and management. However, some traditional monitoring protocols lack the information needed to account for sources of measurement error in data analyses.

Factors affecting feed conversion ratios in US commercial catfish production ponds

Journal of the World Aquaculture Society, Volume 55, Issue 3, June 2024.
Abstract Feed conversion ratio (FCR) is widely used as a measure of feed use efficiency in commercial aquaculture production and research. Surprisingly, little work has focused on the factors that affect FCR in plankton‐based, commercial ponds despite the widespread use of FCR as a production metric.

Acoustic telemetry tracking of Coho Salmon smolts released from a community‐run hatchery into a marine inlet reveals low early ocean survival

North American Journal of Fisheries Management, Volume 44, Issue 2, Page 359-376, April 2024.
Abstract Objective Hatcheries are used to help supplement populations of Pacific salmon Oncorhynchus spp. for conservation and fisheries purposes and to provide stewardship opportunities. In British Columbia, small community‐run hatcheries typically focus on the latter and generally do not know the efficacy of their release approaches, unlike larger ...
