Ecologically determined natal philopatry within a colony of great cormorants [PDF]

Behavioral Ecology, 2001
Dispersal patterns of individuals within populations have implications for the social and genetic structure of local populations. Knowing what factors determine individual dispersal behavior is essential for predicting how the population structure will be influenced by environmental and demographic changes.

Steep declines of colonial wading birds in northeastern North America's largest breeding population

Conservation Science and Practice, Volume 8, Issue 7, July 2026.
This study analyzed 22 years of complete nest census data for colonial wading birds in New York–New Jersey Harbor, the largest breeding population in the northeastern United States. Over this period, the total wading bird population decreased by 27%, a rate exceeding average long‐term declines across North American birds.

A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

Ibis, Volume 168, Issue 3, Page 950-971, July 2026.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.

The influence of a cooling water system on waterbird habitat use in a coastal environment

Ibis, Volume 168, Issue 3, Page 1148-1158, July 2026.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.

Fish are not safe from great cormorants in turbid water [PDF]

Aquatic Biology, 2012
Great cormorant populations have shown near-exponential increase in Western Europe over recent decades, generating wildlife management conflicts across the region. It is essential to detail the foraging strategies of this piscivorous predator to understand the functional mechanisms determining its actual impact upon freshwater fisheries.

Update of the risk assessment on emerging and novel brominated flame retardants in food

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The European Commission asked EFSA to update its 2012 risk assessment on Emerging and Novel brominated flame retardants (BFRs) in food. Since the previous Opinion, further information was collected for a total of 27 BFRs. The CONTAM Panel concluded that TDBPP, DBPNG and TBNPA are considered genotoxic and carcinogenic.

Protected fish predator in a protected area: impact of the Great Cormorant (Phalacrocorax carbo L.) on fish populations in the Raszyńskie Ponds Nature Reserve (Central Poland)

The European Zoological Journal
The Raszyńskie Ponds Nature Reserve, established in 1978, is an ornithological reserve that provides key breeding, foraging, and resting habitats for water and marsh birds.

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 305-322, June 2026.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

High resolution data reveal fundamental steps and turns in animal movements

Ecological Monographs, Volume 96, Issue 2, May 2026.
Abstract Animal movement paths display substantial complexity and variability, promoting efforts to identify universal rules and models that best describe them. Using high‐resolution (≥10 Hz) movement from 43 vertebrate species spanning diverse taxa, body sizes, and lifestyles, we show that paths are universally composed of straight‐line steps ...

Spatial‐temporal patterns of perfluoroalkyl substances in the biota of the Laurentian Great Lakes: A meta‐analysis

Journal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract To better understand the dynamics of per‐ and polyfluoroalkyl substances (PFAS) in complex freshwater ecosystems, we performed a systematic meta‐analysis of PFAS distributions and spatiotemporal variance in biota of the Laurentian Great Lakes watersheds.
