Environmental DNA (eDNA) is increasingly being used to assess community composition in marine ecosystems. Applying eDNA approaches across broad spatial scales now provide the potential to inform biogeographic analyses. However, to date, few studies have employed this technique to assess broad biogeographic patterns across multiple taxonomic groups. Here, we compare eDNA-derived communities of bony fishes and invertebrates, including corals and sponges, from 15 locations spanning the entire length of the Omani coast. This survey includes...
Prevalence of Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans in thre Hoang Lien Range, northwest VietnamBenjamin Tapley, Phillip Jervis, Luan Nguyen, Christopher Portway, Chung Nguyen, Hao Luong, Daniel Kane, Lola Brookes, Matthew Perkins, Pria Ghosh, Claudia Wierzbicki, Jennifer Shelton, Matthew Fisher & Jodi Rowley
This study aims to investigate the presence of the amphibian chytrid fungi Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal) in the Hoang Lien Range, northwest Vietnam as well as any patterns in Bd infection in space, time and host species over a five-year sampling period. This study also aims to investigate the presence of Bsal in the Hoang Lien Range.
Rising temperatures and extreme climatic events are propelling tropical species into temperate marine ecosystems, but not all species can persist. Here, we used the heatwave-driven expatriation of tropical black rabbitfish (Siganus fuscescens) to the temperate environments of Western Australia to assess the ecological and evolutionary mechanisms that may entail their persistence. Population genomic assays for this rabbitfish indicated little genetic differentiation between tropical residents and vagrants to temperate environments due to high migration rates, which...
Monitoring plans using environmental DNA have the potential to offer a standardized and cost-efficient method to survey biodiversity in aquatic ecosystems. Among these ecosystems, coastal wetlands are key elements that serve as transition zones between marine and freshwater ecosystems and are today the target of many conservation and restoration efforts. In this sense, eDNA monitoring could provide a rapid and efficient tool for studying and generating baseline biodiversity information to guide coastal wetland management programs....
Increasing fishing effort, including bycatch and discard practices, are impacting marine biodiversity, particularly among slow-to-reproduce taxa such as elasmobranchs, and specifically sharks. While some fisheries involving sharks are sustainably managed, collateral mortalities continue, contributing towards > 35% of species being threatened with extinction. To effectively manage shark stocks, life-history information, including resource use and feeding ecologies is pivotal, especially among those species with wide-ranging distributions. Two cosmopolitan sharks bycaught off eastern Australia are the common...
Wildlife species impacted by habitat loss and fragmentation often require conservation efforts to maintain populations. Long-nosed bandicoots (Perameles nasuta) still persist within the highly urbanised matrix of northern Sydney (Australia). These data are from a conservation genetics project investigating population structure and genetic diversity of the North Head Long-nosed bandicoot (Perameles nasuta) population and individuals from surrounding suburbs throughout northern Sydney. The population at North Head, Sydney, is currently listed as an Endangered population due...
The Devonian record presents an opportunity to test and validate an existing marine bioregionalisation. This study is the first to use comparative biogeography and phylogenetic data to test Devonian bioregionalisation. Proposed in the 1960’s the Old World, Eastern Americas, and Malvinokaffric realms have been the functional standard within marine Devonian Biogeography. Data from 32 published phylogenies of Devonian marine taxa and a database of c.800 occurrences were analysed using phylogenetic software to test for area...
