Taxonomic sampling and rare genomic changes overcome long-branch attraction in the phylogenetic placement of pseudoscorpions

Long-branch attraction is a systematic artifact that results in erroneous groupings of fast-evolving taxa. The combination of short, deep internodes in tandem with LBA artifacts has produced empirically intractable parts of the Tree of Life. One such group is the arthropod subphylum Chelicerata, whose backbone phylogeny has remained unstable despite improvements in phylogenetic methods and genome-scale datasets. Pseudoscorpion placement is particularly variable across datasets and analytical frameworks, with this group either clustering with other long-branch...

Etadunna bandicoot tip dated matrices

Kenny Travouillon
The oldest fossils referrable to the marsupial order Peramelemorphia (which includes modern bandicoots and bilbies) dates to the late Oligocene of Australia. The earliest geologically speaking of these are from the Etadunna Formation in central Australia. Here we describe additional peramelemorphian material from the Etadunna Formation, as well as specimens from the Namba and Wipajiri Formations. The new material fills gaps in the evolutionary history of the order showing that peramelemorphians were present in every...

Data from: Metabarcoding under Brine: Microbial ecology of five hyper-saline lakes at Rottnest Island (WA, Australia)

Mattia Saccò, Nicole E. White, Matthew Campbell, Sebastian Allard, William F. Humphreys, Paul Pringle, Farid Sepanta, Alex Laini & Morten E. Allentoft
Hypersaline ecosystems - aquatic environments where concentration of salt exceeds 35 g/L - host microbial communities which are highly specialized to cope with these extreme conditions. However, our knowledge on the taxonomic diversity and functional metabolisms characterising microbial communities in the water columns of hypersaline ecosystems is still limited, and this lack of knowledge may compromise the future preservation of these unique environments. DNA metabarcoding provides a reliable and affordable tool to investigate environmental dynamics...

Data from: Population genetics of a broadcast-spawning coral across a tropical-temperate transition zone reveals regional differentiation and isolation of high-latitude reefs

Richard Evans, Luke Thomas, W. Jason Kennington, Nicole Ryan, Nerida Wilson, Zoe Richards, Ryan Lowe & Chenae Tuckett
Aim: Genetic connectivity is a key component of species resilience to climate change in terms of recovery capacity following disturbance and capacity to disperse to novel locations as the climate warms and isotherms shift poleward. We aimed to strengthen our understanding of resilience in this context by characterizing patterns of connectivity and genetic diversity in a broadcast spawning coral across a tropical-temperate transition zone. We hypothesize genetic differentiation between tropical and temperate populations and decreasing...

Home range use in the West Australian seahorse Hippocampus subelongatus is influenced by sex and partner’s home range but not by body size or paired status

Charlotta Kvarnemo, Susanne E. Andersson, Jonas Elisson, Glenn I. Moore & Adam G. Jones
These data and scripts form the basis for Kvarnemo C, Andersson SE, Elisson J, Moore GI and Jones AG (2021). Home range use in the West Australian seahorse Hippocampus subelongatus is influenced by sex and partner's home range but not by body size or paired status. Journal of Ethology 39: 235–248. https://doi.org/10.1007/s10164-021-00698-y. The abstract below is from this paper: Genetic monogamy is the rule for many species of seahorse, including the West Australian seahorse Hippocampus...

Climate-assisted persistence of tropical fish vagrants in temperate marine ecosystems

Joseph DiBattista, Laura Gajdzik, Thomas DeCarlo, Adam Koziol, Mahsa Mousavi-Derazmahalleh, Megan Coghlan, Matthew Power, Michael Bunce, David Fairclough, Michael Travers & Glenn Moore
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...
