Extreme climatic events can reshape the functional structure of ecological communities, potentially altering interactions and ecosystem functioning. While these shifts have been widely documented, evidence their persistence potential flow-on effects on following relaxation extreme remains limited. Here, we investigate changes in trait - encompassing dimensions resource use, thermal affinity, body size herbivorous fishes a temperate reef system that experienced an marine heatwave (MHW)...
Ocean warming is driving species poleward, causing a 'tropicalization' of temperate ecosystems around the world. Increasing abundances tropical herbivores on reefs could accelerate declines in habitat-forming seaweeds with devastating consequences for these important marine ecosystems. Here we document an expansion rabbitfish (Siganus fuscescens), herbivore, Western Australia following heatwave and demonstrate their impact local kelp forests (Ecklonia radiata). Before there were no low rates...
Information about the distribution and abundance of habitat-forming sessile organisms in marine ecosystems is great importance for conservation natural resource managers. Spatial interpolation methodologies can be useful to generate this information from situ sampling points, especially circumstances where remote sensing cannot applied due small-scale spatial variability communities low light penetration water column. Interpolation methods are widely used environmental sciences; however,...
Abstract Seagrass meadows play a key ecological role as nursery and feeding grounds for multiple fish species. Underwater Visual Census (UVC) has been historically used the non-extractive method to characterize seagrass communities, however, less intrusive methodologies such Remote Video (RUV) are gaining interest could be particularly useful habitats, where juvenile camouflage among vegetation easily hide or flee from divers. Here we compared performance of UVC RUV in assessing communities...
The tropicalization of temperate marine ecosystems can lead to increased herbivory rates, reducing the standing stock seaweeds and potentially causing increases in detritus production. However, long-term studies analysing these processes associated with persistence tropical herbivores reefs are lacking. We assessed seasonal variation abundances, macrophyte consumption, feeding modes defecation rates range-extending rabbitfish Siganus fuscescens silver drummer Kyphosus sydneyanus herring cale...
Abstract Climate change is modifying species distributions around the world, forcing some poleward, where they can alter trophic interactions. Many tropical herbivorous fishes have successfully expanded their ranges into temperate ecosystems, and while it clear drive increases in herbivory rates specific localities, little known about how might affect diversity of functions across large spatial scales, considering interaction with assemblages native herbivores habitats. We assessed overlap...
Abstract Global warming is facilitating the range expansion of tropical herbivores, causing a tropicalization temperate marine ecosystems, where herbivores can suppress habitat‐forming macrophytes, supporting resilience canopy‐free ecosystem states. However, currently we lack thorough understanding mechanisms that, on one hand, support persistence and other recovery foundation species in tropicalized required knowledge to predict potential regime shifts reversals baseline state ecosystem....
Abstract Temperate reefs are increasingly affected by the direct and indirect effects of climate change. At many their warm range edges, cool‐water kelps decreasing, while seaweeds with warm‐water affinities increasing. These habitat‐forming species provide different ecological functions, shifts to warm‐affinity expected modify structure associated communities. Predicting nature such at ecosystem level is, however, challenging, as they often occur gradually over large geographical areas....
Abstract Feeding habits of herbivorous fishes play an important role in shaping the form and function coastal marine ecosystems. Rabbitfishes (Siganidae) are consumers macroalgae on Indo‐West Pacific coral reefs. However, it is unclear how their diet varies among within species at biogeographical scales, casting doubt precise functional roles across different regions. The present study assessed inter‐ intra‐specific variation four rabbitfishes ( Siganus trispilos, corallinus, virgatus...
This study presents the first list of fish species from Madagascar Reef, Campeche Bank, Gulf México. Field surveys and literature review identified 54 belonging to 8 orders, 30 families 43 genera, comprising both conspicuous cryptic fishes. Species richness was lower at this reef site compared reefs in Mexican Caribbean, Veracruz or Tuxpan, but similar other same region. composition a mixture present all systems Atlantic.

Global warming is modifying the phenology, life-history traits and biogeography of species around world. Evidence these effects have increased over recent decades; however, we still a poor understanding possible outcomes their interplay across global climatic gradients, hindering our ability to accurately predict consequences climate change in populations ecosystems. We examined effect that changes can on two most successful range-extending fish world: tropical rabbitfishes Siganus...
Marine fish communities are highly diverse, including all trophic levels of consumers and contributing to many ecosystem processes. Understanding the specific functional roles species importance different prey groups for sustaining has, however, been limited by historical classification fishes into a few coarse guilds. Using detailed diet information perform high-resolution 298 temperate reef distributed across south-western Australia, we built metacommunity network evaluate most important...
