The low pH of naturally acidic aquatic environments is the result of soft-water with low buffering capacity and high concentrations of natural organic acids. Our current understanding of the influence of pH on aquatic organisms is largely limited to laboratory studies conducted under controlled conditions with little incorporation of these organic acids. Recent studies suggest natural organic a...

Environmental conditions during embryonic development can influence the mean expression of phenotypes as well as phenotypic responses to environmental change later in life. The resulting phenotypes may be better matched to their environment and more resilient to environmental change, including human-induced climate change. However, whether plasticity does improve success in an ecological contex...

Declines in abundance of sea snakes have been observed on reefs throughout the Indo-Pacific, although reasons are unknown. To date, surveys occurred shallow reefs, despite occurring over a large depth range. It is not known if populations deep habitats undergone similar declines. address this, we analysed deep-water video data from historical hotspot snake diversity, Ashmore Reef, 2004, 2016, a...

Globally, river regulation has degraded wetlands, including parts of the Murray-Darling Basin (MDB), an ecologically significant basin in Australia. Frogs a floodplain environment largely depend on habitats created by flows, but little is known about how frogs northern MDB are impacted regulation. We tested wetland inundation affected catchment MDB. surveyed between 2015 and 2019 to determine l...

One of the most devastating impacts of an invasive species is the introduction of novel parasites or diseases to native fauna. Invasive cane toads (Rhinella marina) in Australia contain several types of parasites, raising concern that the toads may increase rates of parasitism in local anuran species. We sampled cane toads and sympatric native frogs (Limnodynastes peronii, Litoria latopalmata, ...

Eighteen species of delphinids have been recorded from Africa, south l 7°S. This review includes analyses the distribution and status, life history feeding habits for each species, primarily using published data strandings, incidentally caught animals sightings. Although there is little known most distributed over continental shelf, it appears that presently human-induced threat to these. Howev...
