Abundance, population trends, and negative associations with lake water levels for six colonial waterbird species over five decades in southern Manitoba

Avian Conservation and Ecology, 2021
Management of colonial waterbirds at regional, national, and continental scales requires up-to-date monitoring information on breeding locations, population sizes, and trends.

Monitoring faunal responses to biodegradable oyster reef restoration materials with camera traps in a subtropical estuary

Restoration Ecology, Volume 33, Issue 8, November 2025.
Oyster reef restoration has become increasingly crucial due to global population declines. Intertidal oyster reefs provide essential foraging and loafing (resting) grounds to estuarine fauna. To reduce plastic pollution from traditional materials, biodegradable restoration materials have been introduced and are shown to support oyster recruitment ...

Bayesian integrated species distribution models for hierarchical resource selection by a soaring bird

Ecological Informatics
Migratory birds exhibit seasonal geographic range (hereafter, range) dynamics during the annual cycle. Few studies have examined how migratory birds select their habitats for range occupancy at the species level and space use at the individual level ...

Climate and en route thermals affect long‐term population dynamics of soaring birds

Population Ecology, Volume 67, Issue 4, Page 336-348, October 2025.
The effects of seasonal climate on migrant survival are important for migration ecology. We estimated the survival of American White Pelicans and examined the impacts of climate and wind (a–d). We found that increases in winter precipitation enhanced the annual survival rates of yearlings and adults (b and c).

Bait trapping of waterfowl increases the environmental contamination of avian influenza virus (AIV)

The Journal of Wildlife Management, Volume 89, Issue 3, April 2025.
Metrics of avian influenza virus (AIV) occurrence and diversity derived from fecal and sediment sampling at quasi‐experimentally baited and un‐baited sites provided evidence that wetland baiting of waterfowl increases AIV contamination in the environment.

A Trophic and Non‐Trophic Seasonal Interaction Network Reveals Potential Management Units and Functionally Important Species

Global Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim Understanding the organisation of the wide variety of ecological interactions is crucial to advancing our understanding and management of real ecosystems. We aimed to compile a ‘complete’ network of tetrapod trophic and non‐trophic interactions for the entire North American boreal forest biome that could be analysed to gain insights into ...

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.
