Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been … developed to evaluate population genetic trends without necessarily collecting new genetic data. Such "genetic diversity … indicators" enable rapid…
Molecular tools are increasingly applied for assessing and monitoring biodiversity and informing conservation action. While recent developments in genetic and genomic methods provide greater sensitivity in analysis and the capacity to address new questions…
As the use of coastal and offshore environments expands, there is a need to better understand the exposure of marine megafauna to anthropogenic activities that potentially threaten their populations. Individual satellite telemetry studies are often hampered by small sample sizes…
Whale sharks (Rhincodon typus) are thought to aggregate in nearshore waters around Christmas Island … (105◦37E, 10◦29S) to consume the marine larvae of the endemic red land crab (Gecarcoidea natalis). However, there … have been no direct observations of sharks feeding on crab larvae.

As part of a general survey of the biodiversity and inherent ecophysiology of bacteria associated with coastal Antarctic sea-ice diatom assemblages, eight strains were identified by 16S rRNA sequence analysis as belonging to the genus Colwellia. The isolates were non-pigmented…
A group of pigmented, psychrophilic, strictly aerobic chemoheterotrophs isolated from sea-ice cores collected from coastal areas of eastern Antarctica was found to represent a novel 16S rRNA lineage within the gamma subclass of the Proteobacteria, adjacent to the genus Alteromonas.
A group of sea-ice-derived psychrophilic bacterial strains possessing the unusual ability to synthesize the polyunsaturated fatty acids eicosapentaenoic acid (20:5w3) and arachidonic acid (20:4w6) belong to the Family Flavobacteriaceae (Flexibacter–Bacteroides–Flavobacterium phylum)…

Molecular based and traditional microbiological techniques were utilized to determine thestructure and degree of cold adaptation of a variety of Antarctic bacterial communities.
