DNA reveals the past and future of coral reefs
New DNA techniques are being used to understand how coral reacted to the end of the last ice age in order to better predict how they will cope with current changes to the climate. James Cook Univer
From 2005 to 2022, the main node of the ARC Centre of Excellence for Coral Reef Studies was headquartered at James Cook University in Townsville, Queensland (Australia)
David Boseto is from the Solomon Islands and is currently undertaking Graduate Studies in Masters in Environmental Science at Texas A&M University-Corpus Christi. David’s current research projects are Freshwater fisheries policy in the Pacific Island Nations and a review of the sicydiinae goby of the genus Stiphodon. Other research interests are on the effect of aquatic invasive species on the native species and the effect of the global climate change on the freshwater fishes of the Pacific island nations.
One of the poorly known aspects of the biodiversity of the Pacific Islands is the biodiversity of freshwater fish. In insular Pacific islands, freshwater streams and rivers are dominated by seven families of freshwater fishes. These families are: Gobiidae, Eleotridae, Kuhliidae, Syngnathidae, Mugilidae, Anguillidae and Poeciliidae. A number of marine fish families are usually found in estuarine areas including the Carangidae, Chanidae, Muraenidae, Carcharhinidae and Toxotidae. Gobiidae are the most abundant fish in freshwater on insular Pacific islands. They are present in a wide range of aquatic habitats from the ocean into the head waters of rivers. Gobies of the subfamily sicydiinae inhabit high tropical volcanic islands throughout the insular Pacific islands. They are known as the mountain climbing marine fishes. They have cleft in their mouth, their disc –like pelvic fin and pectoral fin that aid them to climb the waterfall wall to reach a pool at a high elevation. Adults’ species lived in freshwater and in some high islands they are the only fish in the rivers. Sicydiinae gobies spawn in the river and the larvae washed down to the sea where they developed into juvenile before returning back to the river to complete their life cycle. Most of the freshwater biota of the Pacific islands represents secondary species derived from marine ancestors

A new study on the effects of climate change in five tropical countries has found fisheries are in more trouble than agriculture, and poor people are in the most danger. Distinguished Profess
James Cook University researchers have found brightly coloured fish are becoming increasingly rare as coral declines, with the phenomenon likely to get worse in the future. Christopher Hemingson, a
Researchers working with stakeholders in the Great Barrier Reef region have come up with ideas on how groups responsible for looking after the reef can operate more effectively when the next bleaching
Abstract: As marine species adapt to climate change, their heat tolerance will likely be under strong selection. Individual variation in heat tolerance and its heritability underpin the potential fo
Abstract: The Reef Ecology Lab in KAUST’s Red Sea Research Center explores many aspects of movement ecology of marine organisms, ranging from adult migrations to intergenerational larval dispersal
Abstract: Macroalgal meadows are a prominent, yet often maligned component of the tropical seascape. Our work at Ningaloo reef in WA demonstrate that canopy forming macroalgae provide habitat for ad

Abstract: Evolution of many eukaryotic organisms is affected by interactions with microbes. Microbial symbioses can ultimately reflect host’s diet, habitat range, and even body shape. However, how
Abstract: The past few years have seen unprecedented coral bleaching and mortality on the Great Barrier Reef (GBR) but the consequences of this on biodiversity are not yet known. This talk will expl
