Abstract Aim High‐latitude coral reef communities composed of tropical, subtropical and temperate species are heralded as climate change refuges for vulnerable tropical species, giving them high, but yet unrealized, conservation priority. We review the ecology reefs in context evaluate management strategies ensuring both their own continuity potential to act species. Location Global high‐latitude environments. Methods literature about management, reefs, effects on organisms reefs. Results...
Abiotic filtering is a major driver of gradients in the structure and functioning ecosystems from tropics to poles. It thus likely that environmental an important assembly process at transition biogeographical zones where many species occur their range limits. Shifts abundances association patterns along can be indicative filtering, which predicted stronger areas high abiotic stress promote increased similarity ecological characteristics among co‐occurring species. Here we test these...
Abstract Environmental anomalies that trigger adverse physiological responses and mortality are occurring with increasing frequency due to climate change. At species' range peripheries, environmental particularly concerning because species often exist at their tolerance limits may not be able migrate escape unfavourable conditions. Here, we investigated the bleaching response of 14 coral genera across high‐latitude eastern Australia during a global heat stress event in 2016. We evaluated...
Abstract As marine species adapt to climate change, their heat tolerance will likely be under strong selection. Yet trade-offs between and other life history traits could compromise natural adaptation or assisted evolution. This is particularly important for ecosystem engineers, such as reef-building corals, which support biodiversity yet are vulnerable heatwave-induced mass bleaching mortality. Here, we exposed 70 colonies of the coral Acropora digitifera a long-term heatwave emulation...
Abstract Temperate reefs are at the forefront of warming-induced community alterations resulting from poleward range shifts. This tropicalisation is exemplified and amplified by tropical species’ invasions temperate herbivory functions. However, whether other ecosystem functions similarly invaded species, what drivers, remains unclear. We examine footprints in nine reef fish functional groups using trait-based analyses biomass 550 species across to gradients Japan Australia. discover that...
Understanding range limits is critical to predicting species responses climate change. Subtropical environments, where many overlap at their margins, are cooler, more light‐limited and variable than tropical environments. It thus likely that respond variably these multi‐stressor regimes factors other mean climatic conditions drive biodiversity patterns. Here, we tested hypotheses for scleractinian corals high‐latitude in eastern Australia investigated the role of parameters linked abiotic...
Abstract Long-term demographic studies at biogeographic transition zones can elucidate how body size mediates disturbance responses. Focusing on subtropical reefs in eastern Australia, we examine trends the size-structure of corals with contrasting life-histories and zoogeographies surrounding 2016 coral bleaching event (2010–2019) to determine their resilience recovery capacity. We document shifts, disproportionate declines number small long-term persistence larger corals. The incidence (...
Abstract Subtropical coral assemblages are threatened by similar extreme thermal stress events to their tropical counterparts. Yet, the mid‐ and long‐term responses of corals in subtropical environments remain largely unquantified, limiting our capacity predict future viability. The annual survival, growth recruitment 311 individual within Solitary Islands Marine Park (Australia) was recorded over a 3‐year period (2016–2018), including 2015/2016 event. These data were used parameterise...
ABSTRACT Aim With the global redistribution of species due to warming, accurately quantifying distributions is critical understanding patterns in biodiversity and range shift trajectories. The genus Tripneustes comprises globally important sea urchin taxa that graze seagrass macroalgae have potential transform ecosystems. In eastern Australia, there are two taxa, tropical T. g. gratilla subtropical‐temperate australiae . temperate distribution was considered be a climate‐driven extension...
Abstract Anthropocene coral reefs are faced with increasingly severe marine heatwaves and mass bleaching mortality events. The ensuing demographic changes to assemblages can have long-term impacts on reef community organisation. Thus, understanding the dynamics of subtropical scleractinian populations is essential predict their recovery or extinction post-disturbance. Here we present a 10-yr assessment endemic coral, Pocillopora aliciae (Schmidt-Roach et al. in Zootaxa 3626:576–582, 2013)...
Reef-building corals show a marked decrease in total species richness from the tropics to high latitude regions. Several hypotheses have been proposed account for this pattern context of abiotic and biotic factors, including temperature thresholds, light limitation, aragonite saturation, nutrient or sediment loads, larval dispersal constraints, competition with macro-algae other invertebrates, availability suitable settlement cues micro-algal symbionts. Surprisingly, there is paucity data...
Anthropogenic impacts are typically detrimental to tropical coral reefs, but the effect of increasing environmental stress and variability on size structure communities remains poorly understood. This limits our ability effectively conserve reef ecosystems because specific dynamics rarely incorporated. Our aim is quantify variation in populations across 20 sites along a tropical‐to‐subtropical gradient east coast Australia (~ 23 30°S), determine how changes with sea surface temperature,...
Abstract Subtropical reefs host a dynamic mix of tropical, subtropical, and temperate species that is changing due to shifts in the abundance distribution response ocean warming. In these transitional communities, biogeographic affinity expected predict changes composition, with projected increases tropical declines cool‐affinity species. Understanding population dynamics along transition zones critical, especially for habitat engineers such as sea urchins can facilitate ecosystem through...
Understanding how range-edge populations will respond to climate change is an urgent research priority. Here, we used a phylogenetic community ecology approach examine ecological and evolutionary processes shape biodiversity patterns of scleractinian corals at their high-latitude range limits in eastern Australia. We estimated signal seven ecologically important functional traits conducted tests structure local regional scales using the net relatedness (NRI) nearest taxon indices (NTI) for...
Abstract Climate change is driving rapid and widespread erosion of the environmental conditions that formerly supported species persistence. Existing projections climate typically focus on forecasts acute anomalies global extinction risks. The current also frequently consider all within a broad taxonomic group together without differentiating species‐specific patterns. Consequently, we still know little about explicit dimensions risk (i.e., vulnerability, exposure hazard) are vital for...
This paper reports on a workshop conducted in Australia 2010, entitled 'Management, Conservation, and Scientific Challenges Subtropical Reefs under Climate Change'.

Its primary aim was to identify areas research that need be most urgently addressed improve decision-making framework for managers main findings were sustainable reefs declaration highlights seven priorities These are (i) conduct...
