Global warming and recurrent mass bleaching of corals
TLDR
The distinctive geographic footprints of recurrent bleaching on the Great Barrier Reef in 1998, 2002 and 2016 were determined by the spatial pattern of sea temperatures in each year, suggesting that local protection of reefs affords little or no resistance to extreme heat.
Sex-biased dispersal of great white sharks
In some respects, these sharks behave more like whales and dolphins than other fish.
Movements and swimming behaviour of white sharks (Carcharodon carcharias) in Australian waters
TLDR
The consistency of paths taken by white sharks in Australian waters suggests that they may follow common routes or “highways” in some areas, and identifying such areas may assist in reducing interactions with fishing operations and thus reduce bycatch.
Long-term empirical evidence of ocean warming leading to tropicalization of fish communities, increased herbivory, and loss of kelp
TLDR
An increase in the proportion of warmwater species (“tropicalization”) as oceans warm is increasing fish herbivory in kelp forests, contributing to their decline and subsequent persistence in alternate “kelp-free” states, and posing a significant threat to kelp-dominated ecosystems in Australia and globally.
Potential of video techniques to monitor diversity, abundance and size of fish in studies of Marine Protected Areas
TLDR
Applications of single-video and stereo-video techniques to help survey fish community composition and relative abundance, and fish length and weight are reviewed.
Connectivity within and among a Network of Temperate Marine Reserves
TLDR
Characterise patterns of genetic connectivity of 3 key species of habitat-forming macroalgae across an established network of temperate marine reserves on the east coast of Australia and the implications for adaptive management and marine reserve design suggest that some species are well served but it may be warranted to revisit protection of intertidal habitats to ensure the long-term persistence of important habitat-forms.
Long-term increases in abundance of anemonefish and their host sea anemones in an Australian marine protected area
TLDR
Long-term trends in anemone and anemOnefish abundance at four sites within a ‘no-take’ zone at North Solitary Island, Australia, is examined by comparing data from 2008 to surveys done in 1994 and 1995, with an overall increase in abundance.
Spatial and temporal variation in reef fish assemblages of marine parks in New South Wales, Australia—baited video observations
TLDR
A network of marine parks will be required to represent variation in reef fish assemblages over this latitudinal scale, as observed geographical patterns in species richness of certain families such as Labridae and Monacanthidae followed expectations.
