Data from: Unexpected positive and negative effects of continuing inbreeding in one of the world’s most inbred wild animals

Emily L. Weiser, Catherine E. Grueber, Euan S. Kennedy & Ian G. Jamieson
Inbreeding depression, the reduced fitness of offspring of related individuals, is a central theme in evolutionary biology. Inbreeding effects are influenced by the genetic makeup of a population, which is driven by any history of genetic bottlenecks and genetic drift. The Chatham Island black robin represents a case of extreme inbreeding following two severe population bottlenecks. We tested whether inbreeding measured by a 20-year pedigree predicted variation in fitness among individuals, despite the high mean...

Data from: Too hard to swallow: a secret secondary defence of an aposematic insect

Lu-Yi Wang, Wen-San Huang, Hsin-Chieh Tang, Lung-Chun Huang & Chung-Ping Lin
Anti-predator strategies are significant components of adaptation in prey species. Aposematic prey are expected to possess effective defences that have evolved simultaneously with their warning colours. This study tested the hypothesis of the defensive function and ecological significance of the hard body in aposematic Pachyrhynchus weevils pioneered by Alfred Russel Wallace nearly 150 years ago. We used predation trials with Japalura tree lizards to assess the survivorship of ‘hard’ (mature) vs. ‘soft’ (teneral) and ‘clawed’...

How functionally diverse are fish in the deep? A comparison of fish communities in deep and shallow‐water systems

Victoria Grace Carrington, Yvan Papa, Jessica Hall, Monique A. Ladds, Alice Rogers, Peter Horn, Raphaël Covain & Chelsey M. Beese
Aim: Functional diversity metrics inform how species’ traits relate to ecosystem functions, useful for quantifying how exploitation and disturbance impact ecosystems. We compare the functional diversity of entire fish communities in a shallow-water region with a deep-sea region for further insight into the differences between these ecosystem types. Location: The regions compared in this study were selected to represent a shallow-water coastal region, Tasman and Golden Bays (TBGB), and a deep-sea region, Chatham Rise (CR),...
