In an effort to deliver better outcomes for people and the ecosystems they depend on, many governments civil society groups are engaging natural resource users in collaborative management arrangements (frequently called comanagement). However, there few empirical studies demonstrating social institutional conditions conducive successful comanagement outcomes, especially small-scale fisheries. Here, we evaluate 42 across five countries show that: ( i ) is largely at meeting ecological goals;...
Identifying the rates of recovery fish in no-take areas is fundamental to designing protected area networks, managing fisheries, estimating yields, identifying ecological interactions, and informing stakeholders about outcomes this management. Here we study coral reef fishes through 37 years protection using a space-for-time chronosequence four marine national parks Kenya. Using AIC model selection techniques, assessed trends five ecologically meaningful production models: asymptotic,...
Sustainably managing ecosystems is challenging, especially for complex systems such as coral reefs. This study develops critical reference points sustainable management by using a large empirical dataset on the reefs of western Indian Ocean to investigate associations between levels target fish biomass (as an indicator fishing intensity) and eight metrics ecosystem state. These ecological each exhibited specific thresholds along continuum fishable ranging from heavily fished sites old...
Coral reefs have emerged as one of the ecosystems most vulnerable to climate variation and change. While contribution a warming loss live coral cover has been well documented across large spatial temporal scales, associated effects on fish not. Here, we respond recent repeated calls assess importance local management in conserving context global Such information is important, reef assemblages are species dense vertebrate communities earth, contributing critical ecosystem functions providing...
With marine biodiversity declining globally at accelerating rates, maximising the effectiveness of conservation has become a key goal for local, national and international regulators. Marine protected areas (MPAs) have been widely advocated conserving managing yet, despite extensive research, their benefits non-target species wider ecosystem functions remain unclear. Here, we demonstrate that MPAs can increase resilience coral reef communities to natural disturbances, including bleaching,...
Managing coral reefs for resilience to climate change is a popular concept but has been difficult implement because the empirical scientific evidence either not evaluated or sometimes unsupportive of theory, which leads uncertainty when considering methods and identifying priority reefs. We asked experts reviewed literature guidance on multiple physical biological factors that affect ability resist recover from disturbance. Eleven key inform decisions based scaling achievability quantifying...
Ecology Letters (2011) 14: 341–348 With rapidly increasing rates of contemporary extinction, predicting extinction vulnerability and identifying how multiple stressors drive non-random species loss have become key challenges in ecology. These assessments are crucial for avoiding the functional groups that sustain ecosystem processes services. We developed a novel predictive framework applied it to coral reef fishes. Although relatively few fishes at risk global from climate disturbances,...
Ocean warming under climate change threatens coral reefs directly, through fatal heat stress to corals and indirectly, by boosting the energy of cyclones that cause destruction loss associated organisms. Although cyclone frequency is unlikely rise, intensity predicted increase globally, causing more frequent occurrences most destructive with potentially severe consequences for reef ecosystems. While increasing considered a pervasive risk reefs, quantitative estimates threats from...
Coral reefs provide ecosystem goods and services for millions of people in the tropics, but reef conditions are declining worldwide. Effective solutions to crisis facing coral depend part on understanding context under which different types conservation benefits can be maximized. Our global analysis nearly 1,800 tropical reveals how intensity human impacts surrounding seascape, measured as a function population size accessibility ("gravity"), diminishes effectiveness marine reserves at...
Ecologists often rely on observational data to understand causal relationships. Although inference methodologies exist, predictive techniques such as model selection based information criterion (e.g. AIC) remains a common approach used ecological However, approaches are not appropriate for drawing conclusions. Here, we highlight the distinction between and show how can lead biased estimates. Instead, encourage ecologists valid methods backdoor criterion, graphical rule that be determine...
A global survey of coral reefs reveals that overfishing is driving resident shark species toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) assemblages. Our species-level analysis revealed declines 60 to 73% for five common individual were not detected at 34 47% surveyed reefs. As become more shark-depleted, rays begin dominate Shark-dominated assemblages persist wealthy nations with strong governance highly protected areas, whereas poverty, weak governance,...
