Article
Full-text available
As apex and mesopredators, elasmobranchs play a crucial role in maintaining ecosystem function and balance in marine systems. Elasmobranch populations worldwide are in decline as a result of exploitation via direct and indirect fisheries mortalities and habitat degradation; however, a lack of information on distribution, abundance, and population b...
Article
Full-text available
Human activities in coastal areas are accelerating ecosystem changes at an unprecedented pace, resulting in habitat loss, hydrological modifications, and predatory species declines. Understanding how these changes potentially cascade across marine and freshwater ecosystems requires knowing how mobile euryhaline species link these seemingly disparat...
Article
We report 24 new records of the Brazilian cownose ray Rhinoptera brasiliensis outside its accepted geographic range. Sequencing of a 442-base pair portion of the mito-chondrial NADH dehydrogenase subunit 2 gene for 282 Rhinoptera samples revealed eight records off the east coast of the USA and 16 from the eastern Gulf of Mexico. Both sexes of all l...
Article
• Formerly common in tropical and subtropical waters of the Atlantic Ocean, the Critically Endangered smalltooth sawfish, Pristis pectinata, underwent severe declines over the past century, restricting population(s) to south and south-west Florida in the US, and Bahamian waters. • Anecdotal evidence (e.g. encounter reports from the public) suggests...
Article
Full-text available
Dispersal in many organisms is asymmetric by sex, a pattern that is often identified through the use of genetic tools. Sex-biased dispersal (SBD) is thought to derive from the varying fitness needs of females and males, as mediated by local ecology and life history. SBD is frequently reported in elasmobranchs (sharks, rays), long-lived fishes that...

Full-text available
Understanding the population structure of a species is important to accurately assess its conservation status and manage the risk of local extinction. The Bull Shark ( Carcharhinus leucas ) faces varying levels of exploitation around the world due to its coastal distribution. Information regarding population connectivity is crucial to evaluate its...
Article
Full-text available
The Critically Endangered Smalltooth Sawfish, Pristis pectinata, was once widespread in the tropical and subtropical waters of the Atlantic Ocean, but following substantial declines over the past century, the remaining population(s) are currently confined to Florida in the U.S., and the Bahamas. Recent research and verified public encounter reports...
Article
Full-text available
The Critically Endangered (International Union for Conservation of Nature) largetooth sawfish, Pristispristis , was historically distributed in the tropical Pacific, Atlantic and Indian Oceans. Today, ‘viable’ populations are largely limited to northern Australia. Populations that have suffered from drastic declines in abundance, such as those expe...
Chapter
Full-text available
Conservation genetics is an applied science that utilizes molecular tools to help solve problems in species conservation and management. It is an interdisciplinary specialty in which scientists apply the study of genetics in conjunction with traditional ecological fieldwork and other techniques to explore molecular variation, population boundaries,...
Article
Full-text available
Northern Australia has been identified as the last stronghold for the dwarf sawfish Pristis clavata, green sawfish P. zijsron, and largetooth sawfish P. pristis, making these populations key in global conservation efforts for each species. This research assesses the levels of genetic diversity in these 3 sawfishes in Australian waters, testing for...
Article
Full-text available
This research demonstrates how population structure differs in elasmobranchs with different patterns of habitat use. Population structure was assessed using data at microsatellite loci in three species of Pristis sawfishes in northern Australian waters. Statistically significant population structure was found in each of P. clavata and P. zijsron, w...
Article
Full-text available
Conservation geneticist Nicole Phillips and zoologist Barbara Wueringer reveal how vital northern Australia is to the future of sawfish. Sensitive detector and lethal weapon combined, there are few implements in nature as versatile as the snout of a sawfish. With it, they home in on weak electrical pulses and eddies created by fish and crustaceans,...
Article
Effective management of critically endangered sawfishes can be a difficult task, in part due to interspecies misidentification. Current methods for identifying sawfishes can be impractical as they are based on morphological features that are often unobservable. Further exploration is required to develop a more reliable means of identification.This...
Article
We describe the isolation and characterisation of microsatellite loci for Pagrus auratus and cross amplification in another sparid, Acanthopagrus butcheri. Of 35 loci tested, 12 appear to be appropriate for population genetic studies of P. auratus, which are essential to inform management responses to evidence of overexploitation of this species. T...
Data
Freshwater Sawfish (Pristis microdon) movements and population demographics in the Fitzroy River, Western Australia and genetic analysis of P. microdon and Pristis zijsron. This report is divided into two sections. Section I reports on the habitat use, movements, morphology, population demographics and distribution of the critically endangered Fre...
Article
Full-text available
Acanthopagrus butcheri was restocked in an estuary in which it had become depleted. The restocked fish were cultured in 2001 and 2002 using broodstock from that estuary. These fish, whose otoliths had been stained with alizarin complexone, were released into the estuary and their biological performance tracked for seven to eight years. The 2002 coh...
Article
Full-text available
Northern Australia is considered to be one of the last strongholds for three critically endangered sawfishes, Pristis zijsron, Pristis clavata, and Pristis microdon, making these populations of global significance. Population structure and levels of genetic diversity were assessed for each species across northern Australia using a portion of the mi...
Article
Full-text available
Recent targeted surveys, together with the collection of sawfish (Pristidae) rostra from the general public, have demonstrated that the Kimberley and northern Pilbara are important refuges for sawfish, with four of the world's seven species found here. These comprise all of Australia's known sawfish species, including the three species protected un...
Article
Full-text available
1 and S. PEVERELL 2 DNA was obtained from the skin tissue of a high proportion (198/236) of dry rostra collected during the past ~30 years from the sawfishes Pristis microdon, P. clavata, P. zijsron and Anoxypristis cuspidata. DNA obtained from the dry rostra was usually either non-degraded, or only partly degraded, and was of a quality whereby a 4...
