Can denticle morphology help identify southeastern Australian elasmobranchs?
Journal of Fish Biology, Volume 104, Issue 6, Page 1848-1859, June 2024.Abstract Elasmobranchs are covered in scale‐like structures called dermal denticles, comprising dentine and enameloid. These structures vary across the body of an individual and between species, and are frequently shed and preserved in marine sediments.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 4, April 2024.Abstract Medium‐ to large‐scale marine protected areas (MPAs) are playing an increasingly important role in global marine biodiversity conservation. A key question is “how do we collect relevant data on biodiversity and population trends to inform their design and measure success?” This question is particularly relevant for marine taxa that are ...

Environmental DNA, Volume 6, Issue 1, January–February 2024.At the remote UNESCO Word Heritage Site Te Wāhipounamu, we show that eDNA analysis is a highly sensitive tool with strong potential for biodiversity surveys, which is still limited by the unavailability of local reference data. We hope that by demonstrating the extend of divergence between eDNA and more traditional tools in a real‐life case study of a ...

Papers in Palaeontology, Volume 10, Issue 1, January/February 2024.Abstract This study reports elasmobranch remains from two fossil‐rich horizons in the earliest Danian Olching Formation at Waidach, Austria. These outer neritic assemblages complement previous fine‐scale bulk‐sampling of latest Maastrichtian horizons at Waidach and document a regional elasmobranch faunal turnover across the Cretaceous–Palaeogene (K–Pg)
