Aim Arctic plants survived the Pleistocene glaciations in unglaciated refugia. The number, ages, and locations of these refugia are often unclear. We use high‐resolution genomic data from present‐day and Little‐Ice‐Age populations of Arctic Bell‐Heather to re‐evaluate the biogeography of this species and determine whether it had multiple independent refugia or a single refugium in Beringia. Location Circumpolar Arctic and Coas...

Habitat suitability modelling (HSM) is a tool that is increasingly being used to help guide decision making for conservation management. It can also be used to focus efforts of restoration in our oceans. To improve on model performance, the best available environmental data along with species distribution data are needed. Marine habitats tend to have ecological niches defined by physical environmental conditions and of particu...

Coastal ecosystems, including coral reefs, mangroves, and seagrass, are in global decline. Mitigation approaches include restoration and other managed recovery interventions. To maximise success, these should be guided by an understanding of the environmental niche and geographic limits of foundational species. However, the choices of data, variables, and modelling approaches can be bewildering when embarking on such an exerci...

Offshore platforms, subsea pipelines, wells and related fixed structures supporting the oil and gas (O&G) industry are prevalent in oceans across the globe, with many approaching the end of their operational life and requiring decommissioning. Although structures can possess high ecological diversity and productivity, information on how they interact with broader ecological processes remains unclear. Here, we review the curren...

Although theoretical models consider social networks as pathways for disease transmission, strong empirical support, particularly for indirectly transmitted parasites, is lacking for many wildlife populations. We found multiple genetic strains of the enteric bacterium Salmonella enterica within a population of Australian sleepy lizards ( Tiliqua rugosa ), and we found that pairs of lizards that shared bacterial genotypes were...

Stable social aggregations are rarely recorded in lizards, but have now been reported from several species in the Australian scincid genus Egernia . Most of those examples come from species using rock crevice refuges that are relatively easy to observe. But for many other Egernia species that occupy different habitats and are more secretive, it is hard to gather the observational data needed to deduce their social structure. T...

Summary In this study, we redesigned and evaluated primers for the class Actinobacteria . In silico testing showed that the primers had a perfect match with 82% of genera in the class Actinobacteria , representing a 26–213% improvement over previously reported primers. Only 4% of genera that displayed mismatches did so in the terminal three bases of the 3′ end, which is most critical for polymerase chain reaction success. The...

The Australian lizard Egernia stokesii lives in spatially and temporally stable groups of up to 17 individuals. We have recently shown that these groups are comprised of breeding partners, their offspring and, in some cases, highly related adults, providing the first genetic evidence of a family structure in any lizard species. Here we investigated the mating system of E. stokesii using data from up to eight polymorphic micros...

In this study we used data from six unlinked microsatellite loci to examine stable aggregations of Egernia stokesii , from a population in the southern Flinders Ranges of South Australia. We show that these aggregations are comprised of breeding partners, their offspring from two or more cohorts, and related adults, providing the first genetic evidence of a family structure in any lizard species. Despite this high level of rel...
