Summary: The lack of visible barriers to gene flow in marine coastal species was challenged by molecular studies, which revealed geographically structured genetic differentiation. This study focused on the Parasesarma bidens species complex and found that it consists of at least five distinct clades, resulting from historical sea level changes and oceanic currents during the Pleistocene. The findings highlight the importance of understanding genetic structure and hidden diversity in coastal organisms.

Summary: Conspicuous centers of biodiversity are often attributed to local conditions that promote speciation or resistance to extinction, but recent studies suggest that dispersal may also play a crucial role. This study focuses on the marine diversity hotspot in the Indo-West Pacific among comatulid crinoids, and finds that the hotspot owes its existence to dispersals from the ancient West Tethys rather than in situ diversification.

Summary: This paper investigates the diversity and systematics of the Haloa genus, a group of dull-coloured haminoeid snails found in tropical and sub-tropical Indo-West Pacific waters. The study utilizes both morphological and molecular approaches to identify and delimit species. Thirteen species are recognized, including two new species. The study reveals intraspecific variability in colouration and limited character displacement in anatomy. The shells are not reliable for taxonomy, with male reproductive system and DNA sequences providing more diagnostic information. Some species have restricted distributions, particularly in offshore islands.

Summary: The discovery of multi-species synchronous spawning on the Great Barrier Reef in the 1980s led to efforts to document spawning times globally. The Coral Spawning Database (CSD) compiles data from over 100 sites in the Indo-Pacific region to provide open access for studying coral reproductive biology. The CSD aims to accelerate understanding of coral reproduction and to establish a baseline for evaluating future changes in reproductive patterns.

Summary: Wildlife management requires reliable demographic information to assess the population status and vulnerability. This study calculated demographic parameters and assessed the viability of a community of indo-pacific bottlenose dolphins. The results showed that population changes in this community are influenced by births, deaths, and the migration of juvenile males. To maintain population stability, management actions to reduce adult female and calf mortality should be considered.

Summary: With the development of genomics, it is now possible to sequence thousands of loci from hundreds of individuals at reasonable costs, which allows for the resolution of complex phylogenies. Using the coral genus Pocillopora as a case study, researchers explored the use of multiple criteria (genetics, morphology, biogeography, and symbiosis ecology) to delimit species. The results showed that genomics can be used alongside other criteria to delimit species boundaries and provided insights for the taxonomic revision and conservation of Pocillopora.

Summary: Snubnose gobies are important components of estuarine ecosystems in the Indo-west Pacific, with a diversity close to double the currently recognized species. Australia serves as a hotspot of endemism for these small benthic fishes, with complicated genetic patterns observed in southern regions. The diversity in this group is influenced by factors such as plate tectonics, latitude, and historic barriers, leading to regional panmixia and geographic compartmentalization within landscapes.

Summary: Two species previously referred to as Glossogobius giuris from Australia have been redescribed as Glossogobius giuris and Glossogobius laticeps. They are largely allopatric in Australia, with genetic differences and color pattern variations. The morphological features separating the species are minor, with considerable overlap, and the high variation in certain regions further complicates their separation.

Summary: The study on the biogeographic history of the southern pygmy perch in Australia revealed that sea-level changes and hydrological fluctuations played crucial roles in species divergence and the formation of cryptic species. Isolated climatic refugia and fragmentation of waterways were identified as factors maintaining genetic differentiation of intra- and interspecific lineages. The findings suggest that predicted increases in aridification and sea level due to anthropogenic climate change could have significant demographic impacts on species.

Summary: The study argues that coalescent-based models mostly delineate population structure, not species. The proposed framework for de novo genomic studies includes steps such as visualizing genetic affinities, applying phylogenetic techniques, and assessing diagnosability of lineages. This approach helps address issues of diagnosability and species boundaries in genomic species discovery.

Summary: Under climate change, species without the ability to shift their range rely on genetic variation for adaptation. Genomic vulnerability studies often overlook hybridization as a source of adaptive variation. This study found that hybrid populations of rainbowfish showed reduced vulnerability to climate change compared to pure narrow endemics, highlighting the importance of hybrid populations and adaptive introgression in the evolutionary rescue of species with narrow environmental ranges.

Summary: This study analyzed genetic and environmental data of two ecologically similar and largely co-distributed freshwater fishes, the southern and Yarra pygmy perches, to assess their responses to Plio-Pleistocene climatic changes. The results showed significant differences in responses between the two species, with the southern pygmy perch lacking genetic diversity and historical range expansion. Although some co-occurring populations demonstrated concordant demographic histories, idiosyncratic population size changes were found at the range edges of the more spatially restricted species.
