AbstractCan genetic adaptation in reef-building corals keep pace with the current rate of sea surface warming? Here we combine population genomic, biophysical modeling, and evolutionary simulations to predict future adaptation of the common coralAcropora milleporaon the Great Barrier Reef. Loss of coral cover in recent decades did not yet have detectable effect on genetic diversity in our species. Genomic analysis of migration patterns closely matched the biophysical model of larval dispersal in favoring the spread of existing heat-tolerant alleles from lower to higher latitudes. Given these conditions we find that standing genetic variation could be sufficient to fuel rapid adaptation ofA. milleporato warming for the next 100-200 years, although random thermal anomalies would drive increasingly severe mortality episodes. However, this adaptation will inevitably cease unless the warming is slowed down, since no realistic mutation rate could replenish adaptive genetic variation fast enough.

ErylusGray (Porifera: Geodiidae) has been recorded in Australian waters from two antiquated reports (E. lendenfeldi Sollas, 1888 and E. proximus Dendy, 1916). These two species are redescribed. From more recent collections from the Great Barrier Reef, Coral Sea, southern Queensland and Western Australia four new species (E. amissus, E. circus, E. citrus and E. fromonta, spp. nov.) were discovered and are described. One other, presently unrecognisable, species from an antiquated museum slide preparation is also described. A tabular review of species worldwide is also provided. Erylus has been an important source of novel bioactive compounds, including those with antitumor and antifungal properties and that are helpful in combating autoimmune diseases (including HIV). This discovery of four new species, increasing the diversity of the genus by 66% in Australian waters, has important implications pertaining to the existence of new compounds, or analogues of existing compounds unique to Erylus, as potential therapeutic marine natural products.

It is a glaring fact that climate, and in particular global warming and associated climate change, is having a major impact on life on Earth, and will continue to do so into the forseeable future. The photographs of starving polar bears swimming between broken slabs of melting sea ice in search of food, and Great Barrier Reef coral destroyed by bleaching and cyclonic winds (e.g. Cyclone Hamish down the Great Barrier Reef in 2009), provide graphic and worrying images that clearly document the consequences of human activity. However, what is far less easy to see (quite literally), is complex to interpret, and has worrying consequences for all other life forms on the planet, is the impact climate change is having on microorganisms.

Marked regional differences in dissolved dimethylsulphide (DMS), atmospheric DMS and DMS flux were recorded during July 1997 through the northern Great Barrier Reef, Coral Sea, Gulf of Papua, Solomon and Bismarck Seas. Highest concentrations of dissolved DMS occurred in the Coral Sea, Gulf of Papua and Bismarck Sea, with lower concentrations in the Great Barrier Reef and Solomon Sea. Elevated levels of atmospheric DMS often occurred in south-easterly to southerly trade winds sampled in the region 18°32′–8°12′S to 145°–151°E, where the highest biomass of coral reefs occurred. Atmospheric DMS often increased in the day after low tides and was positively correlated with tidal height in the northern Great Barrier Reef (r = 0.91, P < 0.05). For tides less than 1.6 m, atmospheric DMS increased on the rising tide for the northern GBR and NW Coral Sea (r = 0.66; P < 0.05) and for the whole voyage (r = 0.25; P < 0.05). As coral reefs have been identified as significant sources of DMS, it is suggested that the daytime increase in atmospheric DMS over much of the study area was mainly a result of high winds and extremely low tides in July, which exposed the reefs during the day.
