Success of restoration strategies in preventing extirpation of 2 critically endangered coral species

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected.

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

Ecological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Long‐term effects of moderate and severe hypoxia on growth, intermediary metabolism, monoamine neurotransmitters, and fatty acids in juveniles of coho salmon, Oncorhynchus kisutch

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract Hypoxia concerns have increased in recent decades, reducing fish fitness and becoming a critical challenge in salmon aquaculture. We investigated the effect of long‐term hypoxia on the physiological response of coho salmon (Oncorhynchus kisutch).

Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, Volume 95, Issue 3, Page 397-417, March 2026.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Record phenological responses to climate change in three sympatric penguin species

Journal of Animal Ecology, Volume 95, Issue 3, Page 455-469, March 2026.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.
