Background Resolving threats to widely distributed marine megafauna requires definition of the geographic distributions both as well population unit(s) interest. In turn, because individual can operate on varying spatial scales, their impacts affect different segments a same species. Therefore, integration multiple tools and techniques — including site-based monitoring, genetic analyses, mark-recapture studies telemetry facilitate robust definitions at biological scales address management...
Where conservation resources are limited and targets diverse, robust yet flexible priority-setting frameworks vital. Priority-setting is especially important for geographically widespread species with distinct populations subject to multiple threats that operate on different spatial temporal scales. Marine turtles widely distributed exhibit intra-specific variations in population sizes trends, as well reproduction morphology. However, current global extinction risk assessment do not assess...
Effective conservation strategies for highly migratory species must incorporate information about long-distance movements and locations of high-use foraging areas. However, the inherent challenges directly monitoring these factors call creative research approaches innovative application existing tools. Highly marine species, such as turtles, regularly travel hundreds or thousands kilometers between breeding feeding areas, but identification routes habitat use patterns remains elusive. Here...
Summary 1. Over the last few decades, evidence of marine vertebrate bycatch has been collected for a range industrial fisheries. It recently acknowledged that large impacts may also result from similar interactions with small‐scale fisheries (SSF) due largely to their diffuse effort and number vessels in operation. Marine mammals, seabirds, turtles as well some shark species have reported being impacted by SSF worldwide. 2. From 2000 2007, we used both shore‐based onboard observer programmes...
Abstract Fishery management measures to reduce interactions between fisheries and endangered or threatened species have typically relied on static time‐area closures. While these efforts reduced interactions, they can be costly inefficient for managing highly migratory such as sea turtles. The NOAA TurtleWatch product was created in 2006 a tool the rates of loggerhead turtles with shallow‐set longline gear deployed by Hawaii‐based pelagic fishery targeting swordfish. provides information...
We studied the diet of green sea turtles (Chelonia mydas) at Bahía de los Angeles in Gulf California, México. From 1995–1999, we collected esophageal lavage and fecal samples from live-captured analyzed stomach contents stranded carcasses encountered study area. Foods ingested did not vary with carapace length. Turtles consumed diverse marine algae, filamentous red alga Gracilariopsis lemaneiformis most abundant; other common genera included Gracilaria, Codium, Ulva, Chaetomorpha. also...
The ecologies of vertebrate species have been increasingly studied via stable isotope analyses small quantities body tissues. However, critical assumptions relating to the consistency in isotopic values consumer tissues and their diet as well rate incorporation diet-derived isotopes into remain poorly validated for most taxa despite numerous studies targeting natural systems. In this study, we measured carbon nitrogen diet–tissue discrimination elemental turnover whole blood, red blood...
Summary Animal‐borne instruments provide researchers with valuable data to address important questions on wildlife ecology and conservation. However, these devices have known impacts animal behaviour energetics. Tags deployed migrating animals may reduce reproductive output through increased energy demands or cause phenological mismatches of foraging nesting events. For marine organisms, the only tagging guidelines that exist are based lift thrust birds – concepts do not translate well...
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....
From June 1995 to August 2002 we assessed green turtle ( Chelonia mydas ) population structure and survival, identified human impacts at Bahía de los Angeles, a large bay that was once the site of greatest sea harvest rates in Gulf California, Mexico. Turtles were captured live with entanglement nets mortality quantified through stranding surveys flipper tag recoveries. A total 14,820 netting hours (617·5 d) resulted 255 captures 200 turtles. Straight-carapace length mass ranged from...
Abstract The conservation of highly mobile and migratory species remains one the most serious challenges to resource managers. Intense mortality immature green turtles has been identified at principal developmental–feeding habitats in Baja California, is considered a great threat stability eastern Pacific population. Thus, coastal lagoons California peninsula, such as Bahía Magdalena, have high priority areas for their protection. Conservation efforts date focused on creating sea turtle...
