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

open access: yesIbis, 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

open access: yesIbis, 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.

Improving Living Resource Responses in Ecosystem Restoration: An Illustration Using the Chesapeake Bay

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 3, June 2026.
ABSTRACT Two key components of large‐scale ecosystem restoration planning are: (1) prioritizing individual projects based on how living resources respond, and (2) selecting and analyzing indicators of living resources to assess restoration progress and performance.

Great cormorant (Phalacrocorax carbo) predation on pikeperch (Sander lucioperca L.) in shallow eutrophic lakes in Poland

open access: yesArchives of Polish Fisheries, 2017
Increases in the population abundance of the piscivorous great cormorant (Phalacrocorax carbo) has led to conflicts with fisheries. Cormorants are blamed for decreased fish catches in many lakes in Poland.

Integrating curimba culture during the grow‐out phase of tambaqui affects overall productivity, water quality, and fish health

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract The efficiency of feed use in aquaculture may be improved by integrating the culture of extractive species into fed‐species systems. This study assessed the impact of including curimba (Prochilodus lineatus) in tambaqui (Colossoma macropomum) production during the grow‐out phase in earthen ponds.

The complexity of ecological impacts induced by great cormorants

open access: yesHydrobiologia, 2015
Following decades of global extermination, the general population of the great cormorant (Phalacrocorax carbo L.) is on the rise. The lack of regular predators, highly skilled fish rapacity, rapid metabolism, significant rate of excretion and ability to ...

Effects of farming practices on the performance of fish pond polyculture assessed by trophic modeling

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract This study aimed to identify species compositions that use resources more efficiently and recommend management practices for extensive and semi‐intensive pond polyculture by modeling food webs and calculating performance indicators. We monitored 8 polyculture fish ponds managed by fish farmers that had contrasting fish species compositions in ...
