Detecting and reducing heterogeneity of error in acoustic classification

Methods in Ecology and Evolution, Volume 13, Issue 11, Page 2559-2571, November 2022., 2022
Abstract Passive acoustic monitoring can be an effective method for monitoring species, allowing the assembly of large audio datasets, removing logistical constraints in data collection and reducing anthropogenic monitoring disturbances. However, the analysis of large acoustic datasets is challenging and fully automated machine learning processes are ...

Cranial ecomorphology of turtles and neck retraction as a possible trigger of ecological diversification

Evolution, Volume 76, Issue 11, Page 2566-2586, November 2022., 2022
Abstract Turtles have a highly modified body plan, including a rigid shell that constrains postcranial anatomy. Skull morphology and neck mobility may therefore be key to ecological specialization in turtles. However, the ecological signal of turtle skull morphologies has not been rigorously evaluated, leaving uncertainties about the roles of ...

Timing and magnitude of climate‐driven range shifts in transboundary fish stocks challenge their management

Global Change Biology, Volume 28, Issue 7, Page 2312-2326, April 2022., 2022
We use model projections to explore the timing and intensity in the distribution of marine fish stocks that are shared across the world's Exclusive Economic Zones (EEZ). Our findings suggest that many shared stocks’ distribution and catch are expected to change in most EEZs by 2030.

bRacatus: A method to estimate the accuracy and biogeographical status of georeferenced biological data

Methods in Ecology and Evolution, Volume 12, Issue 9, Page 1609-1619, September 2021., 2021
Abstract Georeferenced biological data of species distributions, abundances or traits are critical for ecological and evolutionary research. However, the accuracy (true vs. false records) and biogeographical status (native vs. alien) of individual georeferenced records are often unclear, which limits their use in species distribution modelling ...
