The costs and benefits of larger brains in fishes
Journal of Evolutionary Biology, Volume 35, Issue 7, Page 973-985, July 2022., 2022 Traits associated with brain size across fishes. Abstract The astonishing diversity of brain sizes observed across the animal kingdom is typically explained in the context of trade‐offs: the benefits of a larger brain, such as enhanced cognitive ability, are balanced against potential costs, such as increased energetic demands.

DNA metabarcoding reveals a broad dietary range for Tasmanian devils introduced to a naive ecosystem
Ecology and Evolution, Volume 12, Issue 5, May 2022., 2022 Top‐order carnivores are essential for maintaining ecosystem stability and biodiversity. We used a metabarcoding and next‐generation sequencing approach to quantify the diet of Tasmanian devils introduced to Maria Island, Tasmania, a site outside the species’ native range.
