Identifying which factors shape the distribution of intraspecific genetic diversity is central in evolutionary and conservation biology. In marine realm, absence obvious barriers to dispersal can make this task more difficult. Nevertheless, recent studies have provided valuable insights into may be shaping structure world's oceans. These were, however, generally conducted on organisms with larval dispersal. Here, using a seascape genetics approach, we show that productivity sea surface...

Abstract Heterogeneous seascapes and strong environmental gradients in coastal waters are expected to influence adaptive divergence, particularly species with large population sizes where selection is be highly efficient. However, these influences might also extend characterized by social structure, natal philopatry small home ranges. We implemented a seascape genomic study test this hypothesis Indo‐Pacific bottlenose dolphins ( Tursiops aduncus ) distributed along the environmentally...
SUMMARY Seals have adapted to the high heat transfer coefficient in aquatic environment by effective thermal insulation of body core. While swimming and diving, excess metabolic is supposed be dissipated mainly over sparsely insulated appendages, whereas location main sinks hauled-out seals remains unclear. Here, we demonstrate windows on trunk harbour seals, harp a grey seal examined under various ambient temperatures using infrared thermography. Thermograms were analysed for location, size...
Abstract Climatic oscillations during the P leistocene have greatly influenced distribution and connectivity of many organisms, leading to extinctions but also generating biodiversity. While effects such changes been extensively studied in terrestrial environment, studies focusing on marine realm are still scarce. Here we used sequence data from one mitochondrial five nuclear loci assess potential influence Pleistocene climatic phylogeography demographic history a cosmopolitan predator,...
Abstract Knowledge about the movement ecology of endangered species is needed to identify biologically important areas and spatio-temporal scale potential human impacts on species. Blue whales ( Balaenoptera musculus ) are due twentieth century whaling currently threatened by activities. In Australia, they feed in Great Southern Australian Coastal Upwelling System (GSACUS) during austral summer. We investigate their movements, occupancy, behaviour, environmental drivers inform conservation...
Pygmy blue whales in the South-east Indian Ocean migrate from southern coast of Australia to Indonesia, with a significant part their migration route passing through areas subject oil and gas production. This study aimed at improving our understanding spatial extent distribution, foraging areas, better inform impact assessment anthropogenic activities these regions. Using combination passive acoustic monitoring NW Australian (46 instruments 2006 2019) satellite telemetry data (22 tag...
Abstract Interactions between short‐beaked common dolphins Delphinus delphis and the fishing industry of South Australia (SA) have lead to serious concerns over long‐term viability local dolphin population. Common are gregarious animals with high vagility expected display limited genetic differentiation large spatial scales.

Advances in molecular techniques have enabled the study of genetic diversity and population structure many different contexts. Studies that assess cetacean populations often use biopsy samples from free-ranging individuals tissue stranded animals or became entangled fishery aquaculture equipment. This leads to question how representative location a animal is with respect its natural range, whether similar results would be obtained when comparing carcass studies structure. Here we carcasses...
High levels of standing genomic variation in wide-ranging marine species may enhance prospects for their long-term persistence. Patterns connectivity and adaptation such are often thought to be influenced by spatial factors, environmental heterogeneity, oceanographic geomorphological features. Population-level studies that analytically integrate genome-wide data with information (i.e., seascape genomics) have the potential inform distribution adaptive diversity species, as many mammals. We...
As the use of coastal and offshore environments expands, there is a need to better understand exposure marine megafauna anthropogenic activities that potentially threaten their populations. Individual satellite telemetry studies are often hampered by small sample sizes, providing limited information on spatiotemporal distributions migratory animals relationships threats. We addressed this issue synthesising tracking data from 484 individuals three taxonomic groups six species; turtle, two...

Short-beaked common dolphins ( Delphinus delphis ) are typically considered highly mobile, offshore delphinids. This study assessed the residency of a small community short-beaked in shallow, urbanized Port Phillip Bay, south-eastern Australia. The ability to identify by their dorsal fin markings and coloration using photo-identification was also investigated. Systematic non-systematic boat surveys were undertaken between 2007 2014. Results showed that 13 adult offspring inhabit which 10...
An understanding of population structure and connectivity at multiple spatial scales is required to assist wildlife conservation management. This particularly critical for widely distributed highly mobile marine mammals subject fisheries by-catch. Here, we present a genomic assessment near-top predator, the common dolphin ( Delphinus delphis ), which incidentally caught in across Australasian region. The study was carried out using 14,799 ddRAD sequenced genome-wide markers genotyped 478...

Abstract Informed conservation management of marine mammals requires an understanding population size and habitat preferences. In Australia, such data are needed for the assessment mitigation anthropogenic impacts, including fisheries interactions, coastal zone developments, oil gas exploration mining activities.

Abstract Delphinids show a wide range of social structures. However, studies investigating the influence genetic relatedness and maternal kinship on school associations are limited to small number relatively well‐studied delphinid species. This study investigated biparental potential structure in schools short‐beaked common dolphins Delphinus delphis from southern Australian waters. A total 128 biopsy samples were obtained free‐ranging individuals within 62 dolphins. Each sample was...
In South Australia, discrete populations of bottlenose dolphins inhabit two large gulfs, where key threats and population estimates have been identified. Climate change, habitat disturbance (shipping noise pollution), fishery interactions epizootic events identified as the facing these populations. The Population Consequences Disturbance (PCoD) framework has developed to understand how disturbances can influence dynamics. I used combined with specific bioenergetics models undertake a PCoD...
The Australian gummy shark Mustelus antarcticus is distributed across southern and eastern waters the main target of a large fishery. Commercial harvest species considered sustainable based on biomass estimates that show recovery from past overexploitation. However, effective population size genetic-based assessments stock structure remain unresolved.

Conservation management of wildlife species should be underpinned by knowledge their distribution and abundance, as well impacts human activities on populations habitats. Common dolphins ( Delphinus delphis ) are subject to incidental capture in a range Australia’s commercial fisheries including gill netting, purse seining mid-water trawling. The impact these fishery interactions have common dolphin is uncertain, estimates abundance lacking, particularly for the segments at risk bycatch...
