Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.We developed matrix population models for 54 regional populations of 25 marine bird species in the north‐east Atlantic, based on 30 years of monitoring data. In Step 1, we parameterised the models with empirical values for breeding productivity and literature values for survival.

Marine Bird Bycatch in Alaska Salmon Gillnet Fisheries
Fisheries Management and Ecology, Volume 32, Issue 5, Page 366-387, October 2025.ABSTRACT Incidental catch in gillnet fisheries has a substantial conservation impact on marine diving birds. We synthesized available marine bird bycatch data from Alaska salmon gillnet fisheries to estimate standardized bycatch rates, model factors influencing bycatch rates, and estimate total bycatch.

Ibis, Volume 167, Issue 4, Page 1053-1064, October 2025.GPS tracking has enabled significant advances in the study of animal movements such as migration and habitat use. However, GPS devices can affect the behaviour of tagged individuals, especially for flying animals such as birds, and may ultimately impair their reproduction and/or survival.

River Research and Applications, Volume 41, Issue 7, Page 1468-1477, September 2025.ABSTRACT Fishways mitigate barriers blocking fish migration, but their effectiveness varies among species. Whether passage success also varies among individuals of the same species based on their morphology, physiology, or behaviour is largely unknown, particularly for small species.

Journal of Fish Biology, Volume 107, Issue 3, Page 1030-1044, September 2025.Abstract The European catfish Silurus glanis L. continues to spread as an invasive species in Europe. Meanwhile, increasing abundance and range expansions are also suspected within its native distribution. The objective of this study was to characterize the feeding, growth and abundance of S.

Impact of cormorant (Phalacrocorax carbo sinensis L.) colonies on microbial pollution in lakes
Limnological Review, 2013 During 2009-2011 we investigated the effect of perennial and roosting cormorant (Phalacrocorax carbo sinensis) colonies on microbial pollution in 3 lakes: Góreckie (Greater Poland National Park), Chrzypsko (Greater Poland Province) and Ostrowiec (Drawa ...
