Lake eutrophication and brownification downgrade availability and transfer of essential fatty acids for human consumption

Environment International, 2016
Fish are an important source of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) for birds, mammals and humans. In aquatic food webs, these highly unsaturated fatty acids (HUFA) are essential for many physiological processes and mainly ...

Using linear measurements to diagnose the ecological habitat of Spinosaurus [PDF]

PeerJ
Much of the ecological discourse surrounding the polarising theropod Spinosaurus has centred on qualitative discussions. Using a quantitative multivariate data analytical approach on size-adjusted linear measurements of the skull, we examine patterns in ...

Urban waterbirds shifting microplastics

Environmental Challenges
Plastic pollution in aquatic ecosystems poses growing ecological risks, particularly for piscivorous birds occupying higher trophic levels. This study assessed the ingestion and excretion patterns of microplastics (MPs) in two monotypic urban inland ...
