Summary: Lord Howe Island, located 790 km northeast of Sydney, was one of the last islands discovered by humans in 1788. The island originally had a terrestrial avifauna with five endemic species and eight subspecies, but over-hunting and the accidental invasion of black rats led to the extinction of numerous species.

Summary: Thermochemical convective instabilities in the mantle, known as mantle plumes, cause mantle melting that leads to the formation of ocean island basalts (OIB). The radiogenic isotope signatures in global intraplate OIB indicate that individual plumes share enriched components resembling subducted crust and a hypothetical mantle matrix called focal zone (FOZO). Each plume produces variable volumes of melting, resulting in subaerial islands or submarine volcanoes. This study presents the first radiogenic isotope data for lavas from Lord Howe Island (LHI), revealing similarities with the nearby Tasmantid Seamounts but inconsistent with a FOZO-type source. The findings suggest a larger plume under the Tasman Sea and a genetic relation between LHI and the Tasmantid plume track.

Summary: In this study, the developmental toxicities of Triphenyltin (TPT) on coral reef fish were investigated. Results showed that TPT exposure led to increased cumulative mortality and suppressed growth. TPT exposure also disrupted pigmentation development and skeletal development, as well as interfered with thyroid hormones and locomotor behavior. These findings indicate that TPT pollution poses a threat to the development and health of coral reef ecosystems.

Summary: Porolithon is an ecologically important genus of crustose coralline algae, distributed abundantly in tropical and subtropical shallow margins of coral reefs. Sequence comparisons of type specimens and field-collected specimens reveal four unique genetic lineages, suggesting the absence of P. gardineri and P. craspedium in eastern Australia. Furthermore, four new species are discovered, distinguished by growth form, margin shape, and medullary system. Urgent documentation of the taxonomic diversity of Porolithon species is necessary due to their ecological importance and sensitivity to ocean acidification.

Summary: Ocean acidification threatens carbonate-dominated marine systems, like tropical coral reefs, by affecting the ability of organisms to calcify. To assess coral reef flat susceptibility to open ocean acidification, it is crucial to understand the dynamics between carbonate chemistry of open ocean waters and local ecological and hydrodynamic processes. This study measured variations in seawater pH and temperature along coral reef flat transects, complemented by surveys of benthic community composition and reef flat bathymetry. Results showed that reef flat hydrodynamic processes determine spatial pH modifications, with little influence from benthic community composition. As reef flat pH largely mirrors ocean conditions, ocean acidification has an unhindered impact on narrow fringing reef flats.

Summary: This study uses genetic parentage analysis to measure the reproductive success of a size-structured population of a commercially important species of coral grouper in no-take marine reserves in the Great Barrier Reef Marine Park, Australia. Although the per capita reproductive success of individual fish increases rapidly with body length, the numerous young mature female fish below the minimum size limit were responsible for generating disproportionately large contributions towards larval replenishment.

Summary: The study compared multiple life-history traits of the two-spined angelfish across 22 reefs spanning 13 degrees of latitude within the Great Barrier Reef Marine Park and the Coral Sea Marine Park in Australia. While no predictable latitudinal variation was found in mortality rates, growth patterns, growth rates, or maximum length, there were consistent differences in longevity at lower latitudes in the Coral Sea Marine Park. Additionally, individuals of the species were found to be larger on average on continental reefs compared to oceanic reefs at similar latitudes, suggesting that local environmental conditions may have a greater influence on the demographic rates and life-history traits of the angelfish.

Summary: Hybridisation in the marine environment, particularly in coral reef ecosystems, is more common than previously thought. Fish and hermatypic corals show high prevalence of hybridisation, with fish hybrids being linked to biogeographic borders while coral hybrids are not. These findings suggest that hybridisation can influence the evolution of fishes and corals in various ways.

Summary: Substratum preferences and contact interactions among sessile organisms play a crucial role in shaping the structure of benthic communities on coral reefs. This study investigated the substratum preferences and interactions of sponges in coastal coral reefs, revealing their high association with dead coral, coral rubble, and calcium carbonate rock. The most frequent interactions were observed with algae, corals, and crustose coralline algae, with sponges often overgrowing their spatial competitors. Our findings highlight the importance of substratum preferences and interactions in influencing community dynamics on coral reefs.

Summary: Avoiding costly fights can conserve energy needed to survive environmental change, but how resource depletion affects competitor recognition processes in butterflyfishes is poorly understood. We conducted a study using a coral mortality event and field observations to test the impact of rapid resource loss on recognition processes in butterflyfishes. The results showed that competitor recognition became less accurate for heterospecifics after the coral mortality, potentially due to altered resource overlaps.

Summary: Temporal patterns in spawning and juvenile recruitment of coral reef fishes have significant impacts on population size and demographic structure. The study focuses on the commercially important coral grouper and reveals year-round spawning activity with variable peak spawning times and no clear association with environmental cues. The findings suggest the need for additional and longer seasonal closures or alternative fisheries management strategies to maximize recruitment contribution during periods of greatest reproductive success.
