The Eastern Tropical and South-Eastern Pacific region is of global biodiversity importance. At COP26, the governments Costa Rica, Panama, Colombia, Ecuador committed to expansion existing MPAs create a new Mega MPA, safeguarding Marine Corridor. It offers profound step forward in conservation efforts but not specifically designed protect against more diffuse anthropogenic threats, such as plastic pollution. We combine published data with our own unpublished records assess abundance...
Abstract Failure to improve the conservation status of endangered species is often related inadequate allocation resources highest priority issues. Eastern Pacific (EP) leatherbacks are perhaps most sea turtle population in world, and continue on a path regional extinction. To provide coherent, targets, we developed viability analysis examined hypothetical scenarios describing effects activities that either reduced mortality or increased production hatchlings (or both). Under quo conditions,...
In Ecuador, one of the main hazards for threatened marine species, such as sea turtles, is small-scale fisheries bycatch. At a global scale, currently, bycatch reduction technologies (BRTs) are being tested in many coastal nations to mitigate this issue. Despite some advances Ecuadorian efforts wildlife protection, BRTs reduce have yet be assessed. The purpose study was test BRT net illumination using violet light-emitting diodes (LEDs) mitigation measure turtle interactions driftnet fishery...
Abstract Patterns of genetic structure in highly mobile marine vertebrates may be accompanied by phenotypic variation. Most studies turtles focused on population have been performed at rookeries. We studied whether and morphological variation the endangered green turtle (Chelonia mydas) is consistent geographically, focusing foraging grounds. An association between body shape broad (inter-lineage) fine (foraging grounds) scales was predicted analysed using mitochondrial DNA geometric...
Marine litter is a growing environmental problem for which fisheries-sourced waste remains poorly understood. In Peru, there an ongoing challenge of management from the small-scale fisheries fleet given lack facilities to receive variety debris produced by fishers, includes hazardous wastes such as batteries. this study, onboard solid production was monitored daily land-based observers upon landing at port Salaverry, March September 2017. The analysed gillnet and longline fishing fleets...
The East Pacific (EP) leatherback population is listed by the IUCN Red List of Threatened species as Critically Endangered. Despite conservation efforts, mainly focused around nesting areas, its has declined over 90% since 1980s. major current threat fisheries bycatch, but impact been primary documented within South American migration and foraging habitats, with scarce information from or interesting areas. To assess small-scale on EP leatherbacks inhabiting waters north equator we conducted...
Marine species may exhibit genetic structure accompanied by phenotypic differentiation related to adaptation despite their high mobility. Two shape-based morphotypes have been identified for the green turtle ( Chelonia mydas ) in Pacific Ocean: south-central/western or yellow and north-central/eastern black turtle. The between these of environmentally contrasting conditions eastern region has remained a mystery decades. Here we addressed both questions using reduced-representation genome...
Angel sharks are distributed worldwide in tropical to subtropical waters. Across the Eastern Pacific Ocean (EPO), two valid species reported: The angelshark Squatina californica and Chilean armata; however, there is still uncertainty about their geographic distribution, mainly along northern Peru coast where have been reported be sympatric. aim of this study describe genetic differences between genus from EPO, including samples Peru, using DNA barcoding three delimitation models: Poisson...
Environmental DNA (eDNA) has become a powerful tool for assessing biodiversity in different environments and may be complementary method compared to traditional methods assess biodiversity. We tested eDNA as marine at Lobos de Afuera islands (ILA) Peru. Nine water samples were collected from three sites within ILA using commercial kit then analyzed vertebrate, teleost, mammal primers targeting the 12S rRNA gene. Operational taxonomic units (OTUs) classified order, family, genus, species...
Abstract The marine otter ( Lontra felina ) has a patchy distribution associated with rocky coastlines along the Pacific coast of South America. In Peru otters are found from La Libertad (8°04′S) to Tacna (18°09′S), however, few studies have assessed its population and conservation status. To assess otters' current coastline, we conducted visual surveys collected environmental characteristics such as human presence habitat type. We surveyed 20 locations five regions where was based on signs...
