Infographic: Impacts of underwater noise – a helping hand

In their new Practitioner’s Perspective, Guiding principles for assessing the impact of underwater noise, published today (16th May 2018), Faulkner et al. present practical solutions for mitigating the effects of underwater noise on marine wildlife. 522 more words

Research Summary

Good Daphnia parents do not control the offspring microbiome

Author

Angela E. Douglas

All animals are colonized by micro‐organisms, most of which are benign or beneficial. Where do these micro‐organisms come from? Theory predicts that micro‐organisms which are transmitted vertically from parent to offspring are especially likely to be beneficial to the host, while horizontally acquired micro‐organisms are opportunistic and more variable in their impact on host performance. 141 more words

Oxidative stress and antioxidant defense responses in Acartia copepods in relation to environmental factors

On a daily basis, planktonic organisms migrate vertically and thus experience widely varying conditions in their physico-chemical environment. In the Gulf of Finland, these changes are larger than values predicted by climate change scenarios predicted for the next century (up to 0.5 units in pH and 5°C in temperature). 204 more words

Turning microplastics into nanoplastics through digestive fragmentation by Antarctic krill

Microplastics (plastics <5 mm diameter) are at the forefront of current environmental pollution research, however, little is known about the degradation of microplastics through ingestion. Here, by exposing Antarctic krill (Euphausia superba) to microplastics under acute static renewal conditions, we present evidence of physical size alteration of microplastics ingested by a planktonic crustacean. 125 more words

Behavioural responses of Antarctic krill (Euphausia superba) to CO2-induced ocean acidification: would krill really notice?

The Southern Ocean is expected to be significantly affected by future ocean acidification. Antarctic krill (Euphausia superba) is the key species of the Southern Ocean ecosystem. 183 more words

Understanding the stoichiometric limitation of herbivore growth: the importance of feeding and assimilation flexibilities

Authors

Jotaro Urabe, Yuichiro Shimizu, Toshiyasu Yamaguchi

Ecological stoichiometry suggests that herbivore growth is limited by phosphorus when this element in the diet is < 8.6 μg P mg C−1 (C : P atomic ratio > 300). 123 more words
