Does depth divide? Variable genetic connectivity patterns among shallow and mesophotic Montastraea cavernosa coral populations across the Gulf of Mexico and western Caribbean. [PDF]

open access: yesEcol Evol, 2023
We assessed the population genetic connectivity of shallow and mesophotic Montastraea cavernosa corals using a 2bRAD sequencing approach across the Gulf of Mexico and western Caribbean. We found that there was generally significant genetic structuring between shallow and mesophotic depth zones and between the Gulf of Mexico and western Caribbean ...

Simulating drifting fish aggregating device trajectories to identify potential interactions with endangered sea turtles. [PDF]

open access: yesConserv Biol
Abstract Purse‐seine fishers using drifting fish aggregating devices (dFADs), mainly built with bamboo, plastic buoys, and plastic netting, to aggregate and catch tropical tuna, deploy 46,000–65,000 dFADs per year in the Pacific Ocean. Some of the major concerns associated with this widespread fishing device are potential entanglement of sea turtles ...

Vulnerability of marine megafauna to global at-sea anthropogenic threats. [PDF]

open access: yesConserv Biol
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

A Seascape Genomics Perspective on Restrictive Genetic Connectivity Overcoming Signals of Local Adaptations in the Green Abalone (Haliotis fulgens) of the California Current System. [PDF]

open access: yesEcol Evol
The green abalone exhibits a distinctive neutral genetic structuring influenced by geographic distance and marine currents rather than local adaptations. Analyses using 1900 neutral and 17 putative outlier SNPs revealed three distinct populations: the North group (California to Ensenada, Baja California), a population on Guadalupe Island, and the South

Temperature Conditions in Artificial Sea Turtle Nests: Toward Optimized Hatchery Management. [PDF]

open access: yesEcol Evol
This study examined how environmental and management factors, such as wall distance and egg numbers, influence nest temperatures of Olive Ridley sea turtles in a hatchery on the Pacific coast of Guatemala. ABSTRACT Climate change poses a significant threat to species with temperature‐dependent sex determination, such as sea turtles.

Incorporating cyclone risk in the design of marine protected and conserved areas as an ecosystem-based adaptation approach. [PDF]

open access: yesConserv Biol
Abstract Marine protected and conserved areas (MPCAs) are promoted as an ecosystem‐based adaptation (EbA) approach to increase community and ecosystem resilience to climate change. However, traditional approaches to MPCA design typically do not consider climate risk or habitat condition under a climate threat.

A Warming Southern Gulf of Mexico: Reconstruction of Anthropogenic Environmental Changes From a Siderastrea siderea Coral on the Northern Coast of Cuba

open access: yesPaleoceanography and Paleoclimatology, Volume 38, Issue 12, December 2023., 2023
Abstract The Gulf of Mexico is a vital region for the Atlantic Meridional Overturning Circulation (AMOC), that fuels the exchange of heat between the tropics and the polar regions. A weakening of the AMOC would have dire consequences for the planet. First observations and ocean models show that this process has already started.

Combining otolith chemistry and genetics to infer the population structure of yellow snapper Lutjanus argentiventris

open access: yesEcosphere, Volume 14, Issue 10, October 2023., 2023
Abstract Developing a metapopulation framework contributes to the understanding of spatial processes and structures in populations, providing basic information for conservation biology. However, the extent to which the metapopulation structure differs geographically and across life history stages is unexplored for most fishes.

Hidden demographic impacts of fishing and environmental drivers of fecundity in a sea turtle population

open access: yesConservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Fisheries bycatch is a critical threat to sea turtle populations worldwide, particularly because turtles are vulnerable to multiple gear types. The Canary Current is an intensely fished region, yet there has been no demographic assessment integrating bycatch and population management information of the globally significant Cabo Verde ...

Strandings of cetaceans and sea turtles in the Alboran Sea and Strait of Gibraltar: a long-term glimpse at the north coast (Spain) and the south coast (Morocco)

open access: yesAnimal Biodiversity and Conservation, 2011
Varamientos de cetáceos y tortugas marinas en el mar de Alborán y el Estrecho de Gibraltar: un vistazo a largo plazo de la costa norte (España) y la costa sur (Marruecos) En este estudio se registraron un total de 13 especies de cetáceos y tres especies ...
