Preprint
The blue shark Prionace glauca is a top predator with one of the widest geographic distributions of any shark species, yet classified as critically endangered in the Mediterranean Sea, and Near Threatened globally. Previous genetic studies did not reject the null hypothesis of a single global population across the worldwide species range. Blue shar...

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...
Article
Full-text available
The conservation of threatened elasmobranchs in tropical regions is challenging due to high local reliance on aquatic and marine resources. Due primarily to fishing pressure, river sharks (Glyphis) and sawfishes (Pristidae) have experienced large population declines in the Indo-Pacific. Papua New Guinea (PNG) may offer a refuge for these species, a...
Thesis
Full-text available
Globally, elasmobranch populations (sharks and rays) are declining due to increasing anthropogenic and climate pressures. Genetic connectivity between elasmobranch populations is crucial to ensure their persistence and sustain the ecological integrity of ecosystems. Genetic connectivity implies gene flow among discrete populations occurring via the...
Article
Full-text available
Environmental DNA (eDNA) is recognized as a promising sampling tool for biodiversity monitoring. It has also been proposed as a tool for performing population genetic analyses on target species, but early applications make questionable assumptions, such as assuming that the amount of DNA in the sample is directly related to the number of individual...
Conference Paper
Full-text available
The blue shark Prionace glauca is a cosmopolitan species that inhabits all oceans worldwide except the poles. Several IUCN regional assessments have classified it as Near Threatened, mostly due to overfishing. Previous genetic studies that have used classical genetic markers failed to reject the hypothesis that the species is a single worldwide pop...

Article
With recent advances in sequencing technology, genomic data are changing how important conservation management decisions are made. Applications such as Close‐Kin Mark‐Recapture demand large amounts of data to estimate population size and structure, and their full potential can only be realised through ongoing improvements in genotyping strategies....
Article
Full-text available
Fishing represents a major problem for conservation of chondrichthyans, with a quarter of all species being overexploited. School sharks, Galeorhinus galeus, are targeted by commercial fisheries in Australia and New Zealand. The Australian stock has been depleted to below 20% of its virgin biomass, and the species is recorded as Conservation Depend...
Article
Full-text available
The silvertip shark (Carcharhinus albimarginatus) is a reef-associated shark, with an intermittent distribution across the Indo-Pacific Ocean. Owing to global declines, the species is listed as Vulnerable under the International Union of Conservation for Nature Red List. Samples from 152 C. albimarginatus were collected from three locations: Papua...
Article
Full-text available
Developing efficient, reliable, cost‐effective ways to identify diet is required to understand trophic ecology in complex ecosystems and improve food web models. A combination of techniques, each varying in their ability to provide robust, spatially and temporally explicit information can be applied to clarify diet data for ecological research. Thi...
Article
Full-text available
Tropical reefs are highly diverse ecosystems, and reliable biomonitoring, through diet metabarcoding, is needed to understand present and future trophic relationships in this changing habitat. Several studies have assessed the reliability and effectiveness of single molecular markers; however, a cross-marker validation has rarely been performed. Th...
Article
Early detection of dangerous exotic species is crucial for stopping marine invasions. The New Zealand pygmy mussel Xenostrobus securis is a problematic species in coasts of temperate regions in the northern hemisphere. In this study we have controlled a population of this invader that recently expanded in a north Iberian estuary with both a partici...

This project summarizes initiatives at the global scale and publications where I am involved, focusing on Evolutionary, Conservation and Applied Genomics of Elasmobranches. #Sharks #Rays #Genomics #Bioinformatics #Speciation #Hybridisation #Introgression #Phylogeography #PopulationGenomics #Connectivity #ConservationGenomics #Fisheries #Forensics
Project
The project aims to investigate reproductive connectivity in well-defined river shark (Glyphis glyphis and Glyphis garricki) populations. By applying novel molecular techniques, we will improve our understanding on male-specific gene flow and female philopatry.
