Adaptive management of the Great Barrier Reef: A globally significant demonstration of the benefits of networks of marine reserves

The Great Barrier Reef (GBR) provides a globally significant demonstration of the effectiveness large-scale networks marine reserves in contributing to integrated, adaptive management. Comprehensive review available evidence shows major, rapid benefits no-take areas for targeted fish and sharks, both reef nonreef habitats, with potential fisheries as well biodiversity conservation. Large, mobile species like sharks benefit less than smaller, site-attached fish. Critically, also appear overall ecosystem health resilience: outbreaks coral-eating, crown-of-thorns starfish frequent on reefs, which consequently have higher abundance coral, very foundation ecosystems. Effective require regular compliance: abundances no-entry zones suggest that even may be significantly depleted due poaching.

Larval dispersal and movement patterns of coral reef fishes, and implications for marine reserve network design

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2014, Volume and Issue: 90(4), P. 1215 - 1247

Well-designed and effectively managed networks of marine reserves can be effective tools for both fisheries management biodiversity conservation. Connectivity, the demographic linking local populations through dispersal individuals as larvae, juveniles or adults, is a key ecological factor to consider in reserve design, since it has important implications persistence metapopulations their recovery from disturbance. For protect enhance species fished areas, they must able sustain focal (particularly fishery species) within boundaries, spaced such that function mutually replenishing whilst providing recruitment subsidies areas. Thus configuration (size, spacing location) individual network should informed by larval movement patterns which protection required. In past, empirical data regarding adults many tropical have been unavailable inaccessible practitioners responsible design. Recent studies using new technologies also provided fresh insights into redefined our understanding connectivity among dispersal. Our review 34 families (210 coral reef fishes demonstrates (home ranges, ontogenetic shifts spawning migrations) vary species, are influenced range factors (e.g. size, sex, behaviour, density, habitat characteristics, season, tide time day). Some move <0.1-0.5 km damselfishes, butterflyfishes angelfishes), <0.5-3 most parrotfishes, goatfishes surgeonfishes) 3-10 large parrotfishes wrasses), while others tens hundreds some groupers, emperors, snappers jacks) thousands kilometres sharks tuna). Larval distances tend <5-15 km, self-recruitment common. Synthesising this information allows us, first time, provide specific advice on location ecosystems maximise benefits conservation taxa. We recommend that: (i) more than twice size home (in all directions), thus various sizes will required depending require protection, how far move, if other place outside reserves; (ii) <15 with smaller closely; (iii) include habitats critical life history nursery grounds, migration corridors aggregations), located accommodate these. practical use evaluate monitor effectiveness broader ecological, socioeconomic contexts.

A review of ecogeochemistry approaches to estimating movements of marine animals

Limnology and Oceanography, Journal Year: 2013, Volume and Issue: 58(2), P. 697 - 714

Published: March 1, 2013

Ecogeochemistry—the application of geochemical techniques to fundamental questions in population and community ecology—has been used animal migration studies terrestrial environments for several decades; however, the approach has received far less attention marine systems. This review includes comprehensive meta‐analyses organic zooplankton δ 13 C 15 N values at base food web, dissolved inorganic carbon values, seawater 18 O create, first time, robust isoscapes Atlantic Ocean. These present greater geographic variability multiple tracers than was previously thought, thus forming foundation reconstructions habitat use patterns organisms. We additional tracers, including trace‐element‐to‐calcium ratios heavy element stable isotopes, examine anadromous migrations. highlight value ecogeochemistry by examining case on three components connectivity: dispersal natal homing, functional connectivity, migratory connectivity. also discuss recent advances compound‐specific nitrogen isotope analyses tracking movement. A better understanding isotopic routing fractionation factors, particularly individual compound classes, is necessary realize full potential ecogeochemistry.

Incorporating climate change into systematic conservation planning

Biodiversity and Conservation, Journal Year: 2012, Volume and Issue: 21(7), P. 1651 - 1671

The principles of systematic conservation planning are now widely used by governments and non-government organizations alike to develop biodiversity plans for countries, states, regions, ecoregions. Many the species ecosystems these were designed conserve being affected climate change, there is a critical need incorporate new complementary approaches into that will aid in adjusting potential change impacts. We propose five adaptation can be integrated existing or plans: (1) conserving geophysical stage, (2) protecting climatic refugia, (3) enhancing regional connectivity, (4) sustaining ecosystem process function, (5) capitalizing on opportunities emerging response change. discuss both key assumptions behind each approach trade-offs involved using planning. also summarize additional data beyond those typically required implement approaches.

Designing Marine Reserves for Fisheries Management, Biodiversity Conservation, and Climate Change Adaptation

Coastal Management, Journal Year: 2014, Volume and Issue: 42(2), P. 143 - 159

Published: Feb. 12, 2014

Overfishing and habitat destruction due to local global threats are undermining fisheries, biodiversity, the long-term sustainability of tropical marine ecosystems worldwide, including in Coral Triangle. Well-designed effectively managed reserve networks can reduce threats, contribute achieving multiple objectives regarding fisheries management, biodiversity conservation adaptation changes climate ocean chemistry. Previous studies provided advice ecological guidelines for designing reserves achieve one or two these objectives. While there many similarities guidelines, key differences that provide conflicting advice. Thus, is a need integrated practitioners who wish design all three simultaneously. Scientific advances fish connectivity recovery rates, change vulnerability, also necessitate refining design. Here we review considerations design, simultaneously regarding: representation; risk spreading; protecting critical, special unique areas; size, spacing, location, duration; resilient minimizing avoiding threats. In addition applying must be designed address social governance considerations, within broader coastal management regimes.
