Seabirds are the most threatened group of marine animals and their status has deteriorated rapidly over recent decades. The principal threats are posed by commercial fisheries and global human disturbance including invasive predators and plastic pollution. To cope with these pressures, seabird species specifically need to maintain high levels of genetic diversity, which is only achievable through a high capacity of dispersal among colonies. However, although most seabird species have the ability to travel long distances, several non-physical factors are associated with restricted movement and spatial structuring of genetic variation among colonies, such as differences in foraging strategies and breeding phenology. The aim of my research is to provide practical case studies to investigate those mechanisms in the context of maximising persistence and resilience of seabird populations.
During the first part of my Ph.D project, I used genetic data to elucidate population dynamics and connectivity between colonies of the IUCN listed Vulnerable Providence Petrel Pterodroma solandri, an oceanic seabird restricted to two breeding colonies off eastern Australia; Lord Howe Island and Phillip Island (adjacent to Norfolk Island). These two extant populations show different times of return to nesting sites (diurnal vs. nocturnal), which may influence gene flow between colonies. Quantifying whether this difference in behaviour reflected genetic difference was essential because a planned translocation event on Norfolk Island would potentially bring previously isolated populations back into contact, which may erode any genetic distinctiveness of the small colony established on Phillip Island (See Lombal et al. 2016 and Australian Wildlife Magazine – June 2017).
In the second part of my Ph.D. project, I used mitochondrial/nuclear DNA markers and stable isotopes to investigate genetic and foraging differentiation between colonies of Flesh-footed Shearwaters Ardenna carneipes, a migratory seabird species nesting in the southwest Pacific, southern Australia and the Indian Ocean. There was preliminary evidence that eastern and western colonies migrated to different non-breeding areas. Lack of dispersal between these two group of colonies may have important implications for conservation management of this species as local declines cannot be offset by immigration (see Lombal et al. 2017).
In my last chapter, I combined data from more than 80 genetic studies available in the literature to perform a meta-analysis of the factors affecting genetic structuring within seabird colonies. My results suggest that historical factors dominate biotic factors in the mechanisms of genetic differentiation in seabird species (accepted for publication in Biological Reviews).
During my previous research, I used molecular techniques to investigate genetic connectivity across the range of a North American leaf beetle Chrysomela aeneicollis at the University of Brussels (ULB; see Publication), and to conduct a phylogeny study of a green macroalgae occuring throughout Pacific and Indian Oceans (Halimeda sp.) at the Institute for Research and Development (IRD; see Report – French version) in New Caledonia.
Fascinated by the marine ecosystem, I have been involved in different research projects including the Cetus Project – Cetacean Monitoring in Micronesia – 2014, the 2013 season of observation of Humpback whales Megaloptera novaengliae with Operation Cetaces (see Field work), a mission of dugong Dugong dugong tracking by telemetry (see Informing dugong conservation 2015, James Cook University), and multiple projects involving seabird species (see Field work).
