Our surveys indicated that coral performances varied with taxonomic identity, size and position along environmental gradients, highlighting complex interplays between life-history, warfare-strategy and niche segregation. Our results forewarn that growing alterations of coastal environments may trigger shifts in coral dominance, with the decline of major reef-building taxa like acroporids, and emphasize the importance of limiting human impacts for coastal resilience.

Our empirical approach untangles the complexity of species' battle-like interactions and can help identify winners and losers in various communities caught in the interplay between ecological niches, environmental windows and global changes. Keywords: coral reef, ecological competition, territorial war, niche segregation, species coexistence, global change 1.

Introduction Predicting how global environmental changes will affect species' performances in the future is crucial to anticipating biodiversity declines and defining sustainable management. However, large uncertainties regarding species' responses and future conditions blur current predictions of ecosystem trajectory in future environments [ 1 , 2 ].

Finding effective metrics of species' responses to changing environments is key, particularly for vulnerable ecosystems in need of rapid intervention, and in developing and island nations where high reliance on natural resources exacerbates socio-ecosystem vulnerability [ 3 — 5 ].

This is particularly true with coral reefs, which support prolific marine life and coastal livelihoods yet stand at the frontline of declining ecosystems due to rapidly altering coastal environments [ 1 , 6 — 9 ]. Reef degradation from growing coastal development, pollution, fishing and climate change predominantly involves a gradual decline in coral abundance, composition and size, with the progressive loss of vulnerable species, particularly at sensitive life-stages, altering key ecosystem functions [ 7 , 10 — 13 ].

Recent demographic modelling approaches allow for characterizing these dynamics on reefs using fine-scale monitoring data [ 2 , 14 — 16 ]. However, only a few eminent sites, representing an infinitesimal proportion of reefs, benefit from the necessary level of quantitative knowledge of demographic processes, leaving out most coral reef ecosystems from such quantitative diagnosis. As an alternative to using demographic modelling, we hypothesize that coral competitive performances, the ability of corals to preempt space on the reef substrate through territorial warfare, could be used as a proxy of species' ecological success in different environments.

Competition for space and other limiting vital resources is a key process shaping ecological communities in coral reefs, notorious for biodiversity and biotic interactions, and where competition warfare can drive community shifts and ecosystem collapse in altered environments [ 17 — 19 ].
