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

Ecol 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 ...

Comparative population genomics of manta rays has global implications for management. [PDF]

Mol Ecol
Abstract Understanding population connectivity and genetic diversity is of fundamental importance to conservation. However, in globally threatened marine megafauna, challenges remain due to their elusive nature and wide‐ranging distributions. As overexploitation continues to threaten biodiversity across the globe, such knowledge gaps compromise both ...

Complex patterns of genetic population structure in the mouthbrooding marine catfish, Bagre marinus, in the Gulf of Mexico and U.S. Atlantic. [PDF]

Ecol Evol
Abstract Patterns of genetic variation reflect interactions among microevolutionary forces that vary in strength with changing demography. Here, patterns of variation within and among samples of the mouthbrooding gafftopsail catfish (Bagre marinus, Family Ariidae) captured in the U.S.

True insights or ticking boxes? Rapid assessment of rights‐based management in artisanal fisheries

Fisheries Management and Ecology, Volume 30, Issue 4, Page 338-352, August 2023., 2023
Abstract Rights‐based fisheries management (RBFM) seeks to create market incentives to reduce competition, avoid overexploitation, and increase economic efficiency. Particularly for artisanal fisheries, however, assumptions of RBFM may not be met and its use needs to be carefully considered. This study applies an existing tool (SEASALT) to evaluate the

Re‐estimation of juvenile Isurus oxyrinchus growth in the Mexican Pacific through a multimodel inference approach and verification of growth band periodicity

Journal of Fish Biology, Volume 102, Issue 6, Page 1373-1386, June 2023., 2023
Abstract An update of the age and growth for juveniles of the short fin mako shark (I. oxyrinchus) from the Mexican Pacific is presented, based on the analysis of growth band counts from dorsal vertebrae of 198 individuals [110 females, 74–231 cm of total length (TL) and 88 males, 72–231 cm TL) caught during 2008–2018.

Ontogenetic shifts in feeding habits of orangemouth weakfish (Cynoscion xanthulus): From estuarine benthic feeder to marine nektivore top predator

Marine Ecology, Volume 44, Issue 1, February 2023., 2023
Abstract Orangemouth weakfish is a highly important commercial and game fish species in the Tropical Eastern Pacific. However, studies assessing changes in its trophic ecology relevant to size, habitat (estuarine or marine), sex, and season are non‐existent.

Population genetic structure of the endemic fish Gambusia marshi from the Cuatro Ciénegas basin and its outflow in Coahuila, Mexico

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 8, Page 1263-1276, August 2022., 2022
Abstract The valley of Cuatro Ciénegas in Coahuila, Mexico, has the highest degree of local endemism of any habitat in North America. Despite the arid desert climate, the basin harbours an extensive system of permanent streams, wetlands, and spring‐fed pools, and is divided into two sub‐basins by the central Sierra de San Marcos y Pinos. Microsatellite

Are the Temporal Changes Observed in the Reproductive Biology of the Estuarine Conguito Sea Catfish Related to Increased Small‐Scale Fishing Effort on the Northwestern Pacific Coast of Mexico?

Marine and Coastal Fisheries, Volume 14, Issue 4, August 2022., 2022
Abstract Biological parameters relating to the reproductive biology of Conguito Sea Catfish Cathorops liropus were investigated in 1979–1984 and 2015–2018 from an estuarine system on the northwestern Pacific coast of Mexico. In the first period, the spawning season occurred during the dry–warm season (April–June), according with the percentage of ...

Traditional and Geometric Morphometrics and Invariant Shape Descriptors of Catfish Otoliths in the Yucatán Peninsula: Tools for Species Identification and Individual Size Estimation at Maya Archaeological Sites

Archaeometry, EarlyView.
ABSTRACT This study investigates the use of otolith shape analysis for species identification and size estimation in Ariopsis felis and Bagre marinus, based on 181 modern otoliths obtained from a scientific collection and recent sampling in the coastal regions of Campeche and Yucatán, as well as 39 archaeological otoliths corresponding to the Early ...

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)

Fisheries Oceanography, EarlyView.
ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...
