A wide range of fish species are caught in reef fisheries. However, fishing efforts tend to be highly selective favor large species, which generally have low population growth rates, making them more vulnerable overfishing. When the decline predators occurs, start focus on catching from lower trophic levels, can cause a cascade effect. The objective this research was detect changes density and biomass communities areas with different intensity study area. This carried out Banco Chinchorro...
In the Yucatán Peninsula, anthropogenic activities such as urbanization and final disposal of solids wastewater critically impact aquatic systems. Here, we evaluated anthropogenic-related environmental alteration Lake La Sabana, located in northern limits one main cities Mexican Caribbean. We lake water quality, using physical, chemical, microbiological indicators, heavy metals surficial sediment fish tissue to evaluate potential risk. Multivariate analyses revealed that conditions Sabana...
In the Mexican Caribbean, environmental changes, hydrometeorological events, and anthropogenic activities promote dynamism in coastal vegetation cover associated with dune; however, their pace magnitude remain uncertain. Using Landsat 7 imagery, spatial temporal changes dune were estimated for 2011-2020 period Sian Ka'an Biosphere Reserve. The SAVI index revealed at different magnitudes paces biannual, seasonal, monthly timeframes. Climatic seasons had a significant influence on cover,...
The Mexican Caribbean coastal dune is protected by national and international environmental legislation. However, through permits, concessions authorizations for changes in land use, the has been fragmented or suppressed, mainly touristic activities, causing a decline protective ecological ecosystem services. In this study, we evaluated strength weakness of legislation to protect estimated historical current effects on vegetation geomorphology, associated with legal allowances use change...
WE ANALYZED THE COMPOSITION, DIVERSITY, AND ABUNDANCE OF MARINE FISH AT ROCKY REEFS OFF SAN JOSÉ ISLAND, MEXICO BETWEEN OCTOBER 2001 AUGUST 2002. SPECIES WERE RECORDED USING A VISUAL CENSUS IN 5 SAMPLING AREAS 50 BY METERS 2 DEPTHS, SHALLOW (1-3 METERS) INTERMEDIATE (5-7 METERS). TOTAL 26 946 ORGANISMS COUNTED, BELONGING TO 84 SPECIES. FAMILIES SERRANIDAE (9 SPECIES), LABRIDAE (8), POMACENTRIDAE (7), HAEMULIDAE (6) MOST REPRESENTATIVE. MEASURED RUGOSITY BOTTOM SURFACE, WHICH SHOWED POSITIVE...
The populations of Acropora palmata have decreased over the last four decades, and although there are several studies on their genetic diversity in Caribbean, no been published about reefs from southern Gulf Mexico. This research aimed to determine, using five microsatellite markers, variation three A. Mexican Atlantic located southwest Mexico, Campeche Bank, Caribbean. mean richness (Ng/N) studied was 0.583; lowest estimated value corresponded Bank reef. A low registered (reef He = 0.315 ±...
Background The gray snapper ( Lutjanus griseus ) has a tropical and subtropical distribution. In much of its range this species represents one the most important fishery resources because high quality meat market value. Due to this, is vulnerable overfishing, population declines have been observed in parts range. recent decades, it established that knowing level genetic connectivity useful for establishing appropriate management conservation strategies given isolation can drive towards loss....
Our work shows the efficacy of DNA barcoding for recognizing early stages freshwater fish. We collected 3195 larvae and juveniles. Of them, we identified 43 different morphotypes. After barcodes 350 specimens, ascertained 7 orders, 12 families, 19 genera, 20 species, Barcode Index Numbers, corresponding to putative species. For first time, reported presence brackish Gobiosoma yucatanum in Lake Bacalar. Specimens genus Atherinella sp. Anchoa are possibly new Using both methods, morphology,...
Abstract Kajikia audax, Thunnus albacares, Katsuwonus pelamis, and Auxis spp. occupy high middle-level trophic positions in the food web. They represent important sources for fisheries Ecuador. Despite their ecological economic importance, studies on pelagic species Ecuador are scarce. This study uses stable isotope analysis to assess ecology of these species, determine contribution prey predator tissue. Isotope data was used test hypothesis that medium-sized fish have higher δ15N values...
“El Aerolito” is the most biodiverse cenote cave globally, home to Poecilia velifera and Gambusia yucatana. However, their trophic niches interactions remain undescribed. A total of 53 P. 38 G. yucatana were analyzed for stable isotopes, along with water samples chlorophyll, silicates, physical–chemical parameters. Data collected during norths, rainy, dry seasons in year 2023. Isotopic calculated, a PCA analysis was used assess environmental factors. showed δ13C values −25.4‰, −25.7‰,...
Los patrones de reclutamiento peces aportan información valiosa para entender la dinámica sus poblaciones. El presente trabajo analiza variaciones espaciales y temporales en las abundancias reclutas 4 arrecifales (Stegastes partitus, Chromis cyanea, Gramma loreto Scarus taeniopterus) Banco Chinchorro, Caribe mexicano, mediante censos visuales realizados hábitats cordillera parche febrero 2006 a 2007. La evaluación del hábitat se basó coberturas fondo marino registradas vídeo-transectos...
Los pargos de la familia Lutjanidae son un recurso pesquero importante en las costas mexicanas, con reportes capturas alrededor 12.000 toneladas anuales. El objetivo este estudio fue determinar si existe variación presas consumidas por los océanos Atlántico y Pacífico mexicanos realizando análisis dietario, basado datos publicados, respecto del índice importancia relativa (IIR) para 12 especies pargos: Ocyurus chrysurus, Rhomboplites aurorubens, Lutjanus griseus, L. apodus, analis, synagris,...
