Restoration is becoming a vital tool to counteract coastal ecosystem degradation. Modifying transplant designs of habitat-forming organisms from dispersed clumped can amplify restoration yields as it generates self-facilitation emergent traits, i.e. traits not expressed by individuals or small clones, but that emerge in large clones. Here, we advance science mimicking key locally suppress physical stress using biodegradable establishment structures. Experiments across (sub)tropical and...
Patterns of animal movement associated with foraging lie at the heart many ecological studies and often animals face decisions staying in an environment they know versus relocating to new sites. The lack knowledge sites means there is risk a decision relocate (e.g. poor foraging) as well potential benefit improved foraging). Using unique long-term satellite tracking dataset for several sea turtle species, combined capture-mark-recapture data extending over 50 years, we show how, across...
Abstract Large marine protected areas (MPAs), each hundreds of thousands square kilometers, have been set up by governments around the world over last decade as part efforts to reduce ocean biodiversity declines, yet their efficacy is hotly debated. The Chagos Archipelago MPA (640,000 km 2 ) (Indian Ocean) lies at heart this debate. We conducted first satellite tracking a migratory species, green turtle ( Chelonia mydas ), within and assessed species’ use versus unprotected areas. developed...
Estimating the absolute number of individuals in populations and their fecundity is central to understanding ecosystem role species population dynamics as well allowing informed conservation management for endangered species. Estimates abundance are often difficult obtain rare or cryptic Yet, addition, here we show a charismatic group, sea turtles, that neither nor whose nesting easy observe, traditional approach direct observations has likely led gross overestimation underestimation...
Seagrasses are hugely valuable to human life, but the global extent of seagrass meadows remains unclear. As evidence their value, a United Nations program exists (http://data.unep-wcmc.org/datasets/7) try and assess distribution there has been call from 122 scientists across 28 countries for more work manage, protect monitor (http://www.bbc.com/news/science-environment-37606827). Emerging 12th International Seagrass Biology Workshop, held in October 2016 view that grazing marine megafauna...
Abstract Aim Understanding the spatial ecology of animal movements is a critical element in conserving long‐lived, highly mobile marine species. Analyzing networks developed from six sea turtle species reveals connectivity and can help prioritize conservation efforts. Location Global. Methods We collated telemetry data 1235 individuals reviewed literature to determine our dataset's representativeness. used develop at different scales examine areas, connections, their geographic arrangement....
Abstract Estimating population abundance is central to many ecological studies and important in conservation planning. Yet the elusive nature of species makes estimating their challenging. Abundance estimates sea turtles, marine birds, seals are usually made when breeding adults ashore, while life stages spent at sea, including as juveniles, often poorly sampled. We used a combination high‐resolution satellite tracking (Fastloc‐GPS), uncrewed aerial vehicle (UAV) surveys,...
Abstract Sea level rise has accelerated during recent decades, exceeding rates recorded the previous two millennia, and as a result many coastal habitats species around globe are being impacted. This situation is expected to worsen due anthropogenically induced climate change. However, magnitude relevance of increase in sea (SLR) uncertain for marine terrestrial that reliant on habitat foraging, resting or breeding. To address this, we showcase use low-cost approach assess impacts SLR...
Seagrass meadows are an important wetland habitat that has been degraded globally but carbon storage role. In order to expand the restoration of these productive and biodiverse habitats methods required, can be used for large scale creation across a range environmental conditions. The spreading seagrass seeds proven successful method restoring around world, however in places where tidal is such become limited by resultant water movements. Here we describe test deploying species Zostera...
Abstract Global marine turtle population assessments highlight the importance of south-west Indian Ocean region, despite data gaps for Chagos Archipelago. The archipelago hosts nesting hawksbill Eretmochelys imbricata and green turtles Chelonia mydas, both heavily exploited 2 centuries until protection in 1968–1970. We assessed available habitat spatial distribution activity during rapid surveys 90% archipelago's coastline 1996, 1999, 2006 2016. quantified seasonality mean annual egg clutch...
Abstract Overgrazing may lead to management intervention (e.g. culling, animal relocation) try and prevent habitat destruction. leading seagrass meadow collapse has been recorded for green turtles ( Chelonia mydas ) at several sites around the world, although generality of this phenomenon need widespread destruction is unknown. Where have degraded meadows, home‐ranges are expected be large will relocate as meadows destroyed. We used high resolution Fastloc GPS tracking n = 32 individuals,...
Increasing incubation temperatures may threaten the viability of sea turtle populations. We explored opportunities for decreasing at a Caribbean rookery with extreme female-biased hatchling production. To investigate effect artificial shading, were measured under simple materials (white sheet, white sand, palm leaves). test natural drivers temperature, average nest depths shading on two beaches. Results from pilot experiment suggest most effective material was leaves. Shading decreased by...
Abstract Sand temperatures at nest depths and implications for hatchling sex ratios of hawksbill turtles ( Eretmochelys imbricata ) green Chelonia mydas nesting in the Chagos Archipelago, Indian Ocean are reported compared to similar measurements rookeries Atlantic Caribbean. During 2012–2014, temperature loggers were buried beach zones representative turtle sites. Data collected 12,546 days revealed seasonal spatial patterns sand temperature. Depth effects minimal, perhaps modulated by...
There are major concerns about the ecological impact of extreme weather events. In oceans, marine heatwaves (MHWs) an increasing threat causing, for example, recent devastation to coral reefs around world. We show that these impacts extend adjacent terrestrial systems and could negatively affect breeding endangered species. demonstrate during MHW resulted in bleaching mortality a large, remote protected area, anomalously warm temperatures also occurred on sea turtle nesting beaches. Granger...
Abstract Green turtles ( Chelonia mydas ) are key herbivores of tropical and subtropical neritic habitats play a major role in structuring seagrass meadows. We present the first detailed assessment green turtle diet Western Indian Ocean using gut contents salvaged animals from three atolls Republic Seychelles separated each other by 400–825 km: Cosmoledo (adults, n = 12), Farquhar 33; immature, 1) collected 1982–1983; Desroches (immatures, 8) 2016–2018. report comparison diets gravid females...
Our understanding of global seagrass ecosystems comes largely from regions characterized by human impacts with limited data habitats defined as notionally pristine. Seagrass assessments also focus on shallow-water coastal comparatively few studies offshore deep-water seagrasses. We satellite tracked green turtles (Chelonia mydas), which are known to forage seagrasses, a remote, pristine environment in the Western Indian Ocean, Great Chagos Bank, lies heart one world's largest marine...
