Pedogeochemical Anomalies in Surroundings of Great Cormorant Colony (Case Study in Lithuania)
E3S Web of Conferences, 2013 The area where the colony of great cormorants in Curonian Spit (Lithuania) prospers from 1989 is the study object of “Koreko” project. Based on geochemical results of 90 samples of topsoil from 6 zones which differ according to the influence of the great

The influence of rivers on seabird foraging ecology
Biological Reviews, EarlyView.ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Double‐crested cormorant distribution on catfish aquaculture in the Yazoo River Basin of Mississippi
Wildlife Society Bulletin, 2012 Estimating the catfish aquaculture production losses that can be attributed to double‐crested cormorants (Phalacrocorax auritus) has proved problematic because knowledge of the distribution of cormorants on catfish aquaculture is lacking.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
Biological Reviews, EarlyView.ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over
