Abstract Anthropogenic stressors from climate change can affect individual species, community structure, and ecosystem function. Marine heatwaves (MHWs) are intense thermal anomalies where water temperature is significantly elevated for five or more days. Climate projections suggest an increase in the frequency severity of MHWs coming decades. While there evidence that marine protected areas (MPAs) may be able to buffer species impacts, not sufficient support idea MPAs mitigate large-scale...
Improved management approaches are needed to reduce the rate at which humans depleting exploited marine populations and degrading ecosystems. Networks of no-take reserves promising tools because their potential (1) protect coastal ecosystem structure functioning, (2) benefit fisheries, (3) improve scientific understanding ecosystems, (4) provide enriched opportunities for non-extractive human activities. By protecting ecosystems populations, reserve networks can risk by providing important...
The Nassau grouper (Epinephelus striatus) and other reef fishes aggregate in large numbers at specific locations times to spawn. In Belize, as the rest of Caribbean, about one-third spawning aggregations have disappeared due overfishing. One last still viable Belize has decreased from 15,000 fewer than 3,000 groupers 25 years, a decline more 80%. aggregation was open fishing January 2001, with quota 900 groupers, which represented 30% aggregation. actual catch least 300 groupers.

Abstract Marine protected areas (MPAs) have gained attention as a conservation tool for enhancing ecosystem resilience to climate change. However, empirical evidence explicitly linking MPAs enhanced ecological is limited and mixed. To better understand whether can buffer impacts, we tested the resistance recovery of marine communities 2014–2016 Northeast Pacific heatwave in largest scientifically designed MPA network world off coast California, United States. The consists 124 (48 no‐take...
Abstract A variety of criteria may influence the efficacy networks marine protected areas (MPA) designed to enhance biodiversity conservation and provide fisheries benefits. Meta‐analyses have evaluated MPA attributes on abundance, biomass, size structure harvested species, reporting that size, age, depth, connectivity strength responses. However, few empirical evaluation studies used consistent sampling methodology across multiple MPAs years. Our collaborative research program...
Meta-analyses of field studies have shown that biomass, density, species richness, and size organisms protected by no-take marine reserves generally increase over time. The magnitude timing changes in these response variables, however, vary greatly depend upon the taxonomic groups protected, type reserve, oceanographic regime, time since reserve was implemented. We conducted collaborative, fishery-independent surveys fishes for seven years near newly created areas (MPAs) central California,...
Globally, small-scale fisheries are influenced by dynamic climate, governance, and market drivers, which present social ecological challenges opportunities. It is difficult to manage adaptively for fluctuating except allow participants shift effort among multiple fisheries. Adapting changing conditions allows fishery survive economic environmental disturbances benefit from optimal conditions. This study explores the relative influence of large-scale drivers on shifts in outcomes three...
Abstract Marine Protected Areas (MPAs) are being implemented worldwide, yet there few cases where managers make specific predictions of the response previously harvested populations to MPA implementation. Such needed evaluate whether MPAs working as expected, and if not, why. This evaluation is necessary perform adaptive management, identifying when adjustments management might be achieve goals. Using monitoring data population models, we quantified expected responses targeted species...
Abstract Collaborative fisheries research provides a mechanism for integrating the unique knowledge, experience, and skills of fishermen scientists. It is joint intellectual endeavor that begins with inception project continues until its final stages, each group having mutual investment in—and ownership of—the project. promotes communication trust among fishermen, scientists, managers can provide much‐needed scientifically valid data management. enhance federal state management collection...
Abstract Marine protected areas (MPAs) are widely implemented tools for long‐term ocean conservation and resource management. Assessments of MPA performance have largely focused on specific ecosystems individually rarely evaluated across multiple either in an individual or network. We the 59 MPAs California's large network, which encompasses 4 primary (surf zone, kelp forest, shallow reef, deep reef) bioregions, identified attributes that best explain performance. Using a meta‐analytic...
Abstract Most platforms for collecting images to characterise marine benthic habitats involve a downward or forward‐facing field of view that is relatively constrained (~70°), covering small area benthos (downward ~1 m 2 , forward ~25 ). Here we propose the use four‐camera platform having wide combined (~280°), much greater (up 100 We also present stereo‐camera configuration has added benefit being able accurately measure sample and dimensions biota. The design proposed robust self‐righting,...
It is important to account for the movement behaviour of fishes when designing effective marine protected areas (MPAs). Fish movements occur across different spatial and temporal scales understanding variety essential make correct management decisions. This study describes in detail patterns an economically commercially species, Diplodus sargus, within a well-enforced Mediterranean MPA. We monitored horizontal vertical 41 adult individuals using passive acoustic telemetry up one year....
Integral projection models (IPMs) have a number of advantages over matrix-model approaches for analyzing size-structured population dynamics, because the latter require parameter estimates each age or stage transition. However, IPMs still appropriate data. Typically they are parameterized using individual-scale relationships between body size and demographic rates, but these not always available. We present an alternative approach estimating parameters from time series survey data Bayesian...
