Abstract. Ongoing increases in ocean temperatures are posing significant challenges for marine ectotherms as the rates of their biochemical and physiological processes are largely governed by environmental temperature. The majority of studies to date have related changes in metabolic rates and range shifts to increasing temperatures, however few have examined the potential for behavioural thermoregulation to ameliorate the effects of increasing temperatures. The objective of this project is to investigate the potential for tropical fishes to use small-scale movements to regulate body temperature (i.e., behavioural thermoregulation), and how the variability of a species’ thermal environment influences the propensity to move.
Biography. Tiffany completed her BSc in Marine Biology from the University of West Florida while spending the summers in Wakatobi, Southeast Sulawesi, Indonesia assisting research on how crab-eating frogs and mudskipper fishes tolerate water loss. Furthermore, she assisted in estimating metabolic rates in sea snakes. She earned her MSc here at JCU, and her research investigated how/why fish utilize microhabitats with fluctuating water quality in coral reefs and mangrove ecosystems. She started her PhD in January 2016 expanding upon her interests in microhabitat use. She is supervised by Drs. Jodie Rummer, Andrew Hoey, and Jacob Johansen.

A new study shows the coastal protection coral reefs currently provide will start eroding by the end of the century, as the world continues to warm and the oceans acidify. A team of researchers led

An analytical tool will be used to assess the climate risks facing historic World Heritage sites in Africa—the ruins of two great 13th century ports and the remains of a palace and iron-making indus
Abstract: It is a little over a decade since research commenced into the effects of anthropogenic ocean acidification on marine fishes. In that time, we have learned that projected end-of-century
Abstract: Increased uptake of carbon dioxide from the atmosphere has caused the world’s ocean to become more acidic. Different marine habitats are known to have varying ranges of CO2 across mul
Abstract: The Allen Coral Atlas (http://allencoralatlas.org) partnership uses high-resolution satellite imagery, machine learning, and field data to map and monitor the world’s coral reefs at unp
Abstract: Climate change is causing the average surface temperature of the oceans to rise and increasing the frequency and intensity of marine heatwaves. In addition, absorption of additional CO2
Abstract: Marine environments are a concealing medium, where observations of natural fish behavior are challenging. In particular, the geographic and depth distributions of migratory top predators ar
Abstract: Invasive species management can be the the subject of debate in many countries due to conflicting ecological, ethical, economic, and social reasons, especially when dealing with a species s
Abstract: Ocean acidification, the increase in seawater CO2 with all its associated consequences, is relatively well understood in open oceans. In shelf seas such as the Great Barrier Reef, processe
Abstract: The backdrop of legends and movies, the deep sea has always been unfathomable because we had no idea what existed there. Once thought to be barren of life, we now know this couldn’t be
