Biogeography of the Indo-Australian Archipelago
The conservation significance of the IAA is discussed and the need for cross-taxon comparative studies using newly developed analytical approaches well suited to the challenges of historical inference in this region is highlighted.
Looking forward through the past: Identification of 50 priority research questions in palaeoecology
Using a set of criteria designed to identify realistic and achievable research goals, questions were selected from a pool submitted by the international palaeoecology research community and relevant policy practitioners to highlight its potential for addressing both pure and applied issues related to ecological science and global change.
Patterns of molecular diversity in wild stocks of the redclaw crayfish (Cherax quadricarinatus) from northern Australia and Papua New Guinea: impacts of Plio-Pleistocene landscape evolution
It is demonstrated that wild redclaw crayfish populations consist of two highly divergent Australian lineages and two PNG lineages, and these congruent patterns most probably reflect periodic Plio-Pleistocene land and freshwater connections between Australia and New Guinea.
Phylogeographic evidence for the existence of an ancient biogeographic barrier: the Isthmus of Kra Seaway
Phylogeographic analyses of a freshwater decapod crustacean, the giant freshwater prawn Macrobrachium rosenbergii, strongly supports the historical existence of the more northerly postulated seaway, highlighting the power of utilising intraspecific molecular variation in testing biogeographical hypotheses.

Examination of molecular diversity in wild populations of M. rosenbergii across its complete natural range found 3 clades in the mitochondrial deoxyribonucleic acid (mtDNA) data set that corresponded geographically with eastern, central, and western sets of haplotypes that last shared a common ancestor ∼1 × 106 y ago.
Microsatellite loci in the eastern form of the giant freshwater prawn ( Macrobrachium rosenbergii )
Six microsatellite loci were identified and characterized in the eastern form of the widespread and commercially important giant freshwater prawn and provide powerful tools for the conservation and management of wild stocks, the improvement of cultured stocks of M. rosenbergii, and for investigating evolutionary processes underlying genetic divergence among populations.
Erratum: Environmental DNA for wildlife biology and biodiversity monitoring: [Trends in Ecology & Evolution 29 (2014) 358 – 367]
In 2013 this group undertook an extensive trial of the eDNA approach to test for the presence and abundance of the endangered great crested newt in British freshwaters and suggest that community engagement with eDNA sampling is feasible.
Molecular biogeography and phylogeography of the freshwater fauna of the Indo-Australian Archipelago
The IA houses one of the highest levels of species richness and endemism in the world, encompassing four of the world’s 25 biodiversity ‘hotspots’, which coalesce within this region in Southeast Asia.
Genetic diversity in wild stocks of the giant freshwater prawn (Macrobrachium rosenbergii): Implications for aquaculture and conservation
Wild stock genetic diversity was examined using a 472 base-pair segment of the 16S rRNA gene in 18 wild populations collected from across the natural range of the giant freshwater prawn.
Population differentiation in the context of Holocene climate change for a migratory marine species, the southern elephant seal

It is shown that all breeding colonies of the southern elephant seal are genetically divergent and that connectivity in this highly mobile pinniped is not strongly associated with geographic distance, but more likely linked to Holocene climate change and demographic processes.
