Global climate change threatens tropical coral reefs, yet local management can influence resilience. While increasing anthropogenic nutrients reduce resistance and recovery, it is unknown how the loss, or restoration, of natural nutrient flows affects reef recovery. Here, we test seabird-derived subsidies, which are threatened by invasive rats, mechanisms patterns recovery following an extreme marine heatwave using multiyear field experiments, repeated surveys, Bayesian modeling. Corals...

Behavioural responses are often the first reaction of an organism to human‐induced rapid environmental change (HIREC), yet current empirical evidence provides no consensus about main features that animals respond behaviourally or which behaviours responsive HIREC. To understand how changes in behaviour can be predicted by different forms HIREC, we conducted a meta‐analysis existing literature focusing on behavioural five axes (climate change, CO 2 , direct human impact, nutrients and biotic...

Abstract In a time of unprecedented ecological change, understanding natural biophysical relationships between reef resilience and physical drivers is increasing importance. This study evaluates how wave forcing structures coral benthic community composition recovery trajectories after the major 2015/2016 bleaching event in remote Chagos Archipelago, Indian Ocean. Benthic cover substrate rugosity were quantified from digital imagery at 23 fore sites around small atoll (Salomon) 2020 compared...

Abstract Human-induced environmental changes, such as the introduction of invasive species, are driving declines in movement nutrients across ecosystems with negative consequences for ecosystem function. Declines nutrient inputs could thus have knock-on effects at higher trophic levels and broader ecological scales, yet these interconnections remain relatively unknown. Here we show that a terrestrial species (black rats, Rattus rattus ) disrupts pathway provided by seabirds, ultimately...

Abstract Marine environments are subject to increasing disturbance events, and coral reef ecosystems particularly vulnerable. During periods of environmental change, organisms respond initially through rapid behavioural modifications. Whilst mean population level modifications behaviour well documented, how these shifts vary between individuals, the relative trade-offs that induced, unknown. We test whether frequency time invested in different behaviours varies both within individuals with...
