Drivers of variation in occurrence, abundance, and behaviour of sharks on coral reefs
Quantifying the drivers of population size in reef sharks is critical for the development of appropriate conservation strategies. In north-west Australia, shark populations inhabit coral reefs that border growing centres of human population, industry ...

Parasitic nematodes of marine fishes from Palmyra Atoll, East Indo-Pacific, including a new species of Spinitectus (Nematoda, Cystidicolidae) [PDF]
Here, we present the results of a taxonomic survey of the nematodes parasitizing fishes from the lagoon flats of Palmyra Atoll, Eastern Indo-Pacific. We performed quantitative parasitological surveys of 653 individual fish from each of the 44 species ...

Behaviour of mesopredatory coral reef fishes in response to threats from sharks and humans
Both sharks and humans present a potentially lethal threat to mesopredatory fishes in coral reef systems, with implications for both population dynamics and the role of mesopredatory fishes in reef ecosystems.

On the Movements of the Blacktip Reef Shark (Carcharhinus melanopterus)
One challenge in studying the natural behaviour of wild animals is the requirement of detailed observations spanning extended periods of time, which is particularly difficult in the case of sharks. As a result, remote sensing technologies are increasingly employed in which the data received is considerably simplified.

Coexistence of ecologically similar species occupying the same geographic location (sympatry) poses questions regarding how their populations persist without leading to competitive exclusion.

This study developed and validated the first genus‐specific eDNA assay for epaulette sharks (Hemiscyllium spp.), targeting the NADH4 gene. Field application in Raja Ampat detected H. freycineti at six of seven locations, including one location (Dayan) where daytime visual surveys failed, demonstrating this tool's value for monitoring protected species.

Field Observations of the Behaviour of Blackfin Reef Sharks (Carcharhinus melanopterus)
The chondrichthyan lineage diverged from the osteichthyan line around 440 million years ago, resulting in a vast evolutionary gulf between modern elasmobranchs and other vertebrates. Though this has supported the assumption that sharks are ancient, dangerous, and binary-minded, intelligent actions including social interactions have been noted in the ...
