Early naturalists suggested that predation intensity increases toward the tropics, affecting fundamental ecological and evolutionary processes by latitude, but empirical support is still limited. Several studies have measured consumption rates across latitude at large scales, with variable results. Moreover, how affects prey community composition such geographic scales remains unknown. Using standardized experiments spanned 115° of 36 nearshore sites along both coasts Americas, we found...
Post-hatchling loggerhead turtles ( Caretta caretta ) in the northern Pacific and Atlantic Oceans undertake transoceanic developmental migrations. Similar migratory behaviour is hypothesized South Ocean as post-hatchling are observed Peruvian fisheries, yet no rookeries occur along coast of America. This hypothesis was supported by analyses size-class distribution 123 genetic analysis mtDNA haplotypes 103 nesting females southwest Pacific, 19 post-hatchlings stranded on southeastern...
Abstract We investigated the dispersal, recruitment and migratory behaviour of hawksbill sea turtle ( Eretmochelys imbricata ), among different life‐history stages demographic segments large aggregation at Mona Island, Puerto Rico. There were significant differences in both mitochondrial DNA (mtDNA) haplotype diversity frequencies adult males, females juveniles examined, but little evidence for temporal heterogeneity within these same groups sampled across years. Consistent with previous...
A global phylogeny for chelonid fibropapilloma-associated herpesvirus (CFPHV), the most likely aetiological agent of fibropapillomatosis (FP) in sea turtles, was inferred, using dated sequences, through Bayesian Markov chain Monte Carlo analysis and used to estimate virus evolutionary rate independent evolution host, resolve phylogenetic positions new haplotypes from Puerto Rico Gulf Guinea. Four phylogeographical groups were identified: eastern Pacific, western Atlantic/eastern Caribbean,...
In order to enhance protection and conservation strategies for endangered green turtles (Chelonia mydas), the identification of neritic habitats where this species aggregates is mandatory. Herein, we present new information about population parameters residence time two aggregations from 2010 2013; one in an upwelling dominated site (Paracas ∼14°S) other ecotone zone warm equatorial conditions (El Ñuro ∼4°S) Southeast Pacific. We predicted proportionally more adult individuals would occur...

The first updated and comprehensive checklist of Chondrichthyes from the southeast Pacific off Peru, based on revision scientific literature, is presented. group in Peruvian coast composed 115 species that include 66 sharks, 43 batoids, six chimaeras. We present nine new records one recent discovery obtained secondary sources. For some species, we also compiled extensions geographic distributions.
Abstract Objective Fish populations targeted by recreational and artisanal fisheries remain largely unassessed in low‐ middle‐income countries. This generally results a lack of regulatory action from government agencies, thus aggravating the risk overfishing. In this context, sources historical information, such as local ecological knowledge (LEK), are key to providing insight on status fish informing management. Systematized elicitation processes have increasingly shown an ability produce...
Identifying critical habitats is key to the conservation and recovery of threatened species. A third chondrichthyans (sharks, rays, chimaeras) are with extinction but robust biological ecological information delineate for many species remains limited. Here, we investigated (1) research outputs trends across Central South American Pacific region determine whether sufficient was available identify habitats; (2) regional Important Shark Ray Areas (ISRAs) were spatially representative; (3) what...

The Southeast Pacific comprises two Large Marine Ecosystems, the Central-American Coastal and Humboldt Current System; is one of less well known in tropical subregions terms biodiversity. To address this, we compared DNA barcoding repositories with marine biodiversity species for Pacific. We obtained a checklist (i.e. Colombia, Ecuador, Chile, Peru) from Ocean Biodiversity Information System (OBIS) database it available at Barcoding Life Data (BOLD) repository. Of 5504 records retrieved...
This review examines—with a focus on Peru—the distribution, life-history, ecology, fisheries, historic and contemporary cultural importance, commerce, management of the Pacific guitarfish Pseudobatos planiceps . In eastern Pacific, Peru represents its most important habitats. The only 2 identified Important Shark Ray Areas for this species are in feeding purposes. Other critical habitats unidentified (e.g. reproductive). Most demographic parameters unknown, since length-at-maturity fecundity...
Introduction: Integrating genetic data into conservation management decisions is a challenging task that requires strong partnerships between researchers and managers. Conservation in Latin America of crucial relevance worldwide given the high biodiversity levels presence hotspots this region. Methods: We conducted survey across to identify gaps opportunities aimed better understand managers’ points view how research could help practitioners achieve their goals, by implementing assessments...
Abstract Understanding the population composition and dynamics of migratory megafauna at key developmental habitats is critical for conservation management. The present study investigated whether differential recovery Caribbean green turtle ( Chelonia mydas ) rookeries influenced a major juvenile feeding ground in southern (Lac Bay, Bonaire, Netherlands) using genetic demographic analyses. Genetic divergence indicated strong temporal shift between 2006–2007 2015–2016 ϕ ST = 0.101, P <...
A total of 162 species and subspecies marine macroinvertebrates were recorded in the submerged soft hard substrates around PERU LNG terminal surrounding area, central coast Peru, 167 km south Lima, Peru. The collection specimens was carried out from June 2011 to 2015 as part research studies conducted by Biodiversity Monitoring Assessment Program (BMAP) terminal. area is Humboldt Current Large Marine Ecosystem, one most important upwelling systems world. We identified belonging 83 families...
Abstract Barriers to dispersal are recognized play an important role in the differentiation of populations and ultimately speciation. In southeast Pacific, on northern coast Peru, a transition zone between Peruvian Panamic marine biogeographic provinces exists. Here, convergence two contrasting surface currents could generate barrier effect for larval meroplanktonic invertebrates, which turn differentiated or genetic lineages both sides zone. To address this, we studied Echinolittorina...
