México es de los países con mayor pérdida de superficie de mangle, algo que contribuye a las emisiones de CO2 e impulsa el cambio climático. Sin embargo, falta conocimiento sobre los factores que influyen en la pérdida y la ganancia del manglar, las emisiones de CO2, y la dinámica de usos de suelo y cobertura vegetal a escala local y regional. Por tanto, los objetivos de este estudio fueron analizar la dinámica de uso de suelo en la zona de Marismas Nacionales (México) durante el periodo 1981–2015, determinar la tasa de deforestación y degradación anual del manglar y estimar las emisiones de CO2 derivadas de estos procesos utilizando técnicas de información geográfica. Para determinar los cambios de uso de suelo, con la matriz de tabulación cruzada, se adquirieron diversos parámetros de cambio que permitieron generar una ecuación para estimar la tasa de deforestación y degradación. Con los datos del Inventario Nacional de Emisiones de Gases y Compuestos de Efecto Invernadero (México), se estimaron las emisiones y las absorciones de CO2 (equivalente, CO2e) promovidas por deforestación, degradación, reforestación y recuperación natural de manglares. Para el periodo 1981–2005, la emisión estimada fue de 432.50 Gg de CO2e debido a una tasa anual de deforestación del 0.77%, y la degradación fue de 27.16 Gg de CO2e a una tasa anual de1 7.64%. Para el periodo 2005–2015, la emisión fue de 145.21 Gg de CO2e debido a una tasa anual de deforestación del 0.44%, y la degradación fue de 24.80 Gg de CO2e a una tasa anual del 4.94%. La mayor pérdida de manglar se debió a la transformación a suelos con categorías de agrícola-pecuario y desarrollo antrópico. La degradación sucedió por fenómenos naturales y actividades antropogénicas.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43287283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modifican la distribución de masa y propiedades como calor, sal, clorofila y partículas inertes. La capacidad que tienen los remolinos para transportar propiedades o partículas depende de su capacidad de retención. En este estudio se identificaron y caracterizaron los remolinos de mesoescala del noroeste del golfo de México (NOGM) a través de un método lagrangiano que permite evaluar el tiempo de retención y la fracción de masa que pueden retener y transportar. Para el análisis, se utilizaron datos diarios de altimetría de 1993 a 2016. En el periodo de estudio se detectaron un total de 254 remolinos, 73 anticiclones y 181 ciclones. Se identificó una región (94.75º W, 26.75º N) donde ocurren ~30% del total de los remolinos ciclónicos detectados entre las isóbatas de 1,000 y 2,500 m. En promedio, el radio de los remolinos fue de ~40 km para la isobata <1,000 m y ~70 km para la isobata >2,500 m. Los remolinos de mesoescala del NOGM pueden trasportar ~60% de la masa que contenían al momento de ser detectados. En promedio, el transporte de masa ocurrió por 33 d para los ciclones y por 26 d para los anticiclones. Rara vez ocurrió por 60 d o más.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48420769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared the vegetative and sexual phenology and reproductive effort of Z. marina by analyzing vegetative and reproductive shoot density, biomass, and reproductive stages to determine structural features of vegetative and reproductive shoots from subtidal and intertidal environments in San Quintín Bay, Baja California, a year before and after the 1997–1998 El Niño/Southern Oscillation (ENSO). We found significant differences in vegetative and reproductive biomass between intertidal and subtidal environments driven by temperature differences between ENSO and non-ENSO years. Subtidal plants had lower density of long reproductive shoots and a shorter reproductive cycle. Seed release occurred from May to October in the subtidal environment, and from May to November in the intertidal environment. Maximal recorded values were 219.5 (±45.8) seeds per reproductive shoot in the subtidal environment and 151.3 (±21.5) in the intertidal environment. We observed higher sexual activity and lower vegetative biomass in the intertidal environment, the most stressful environment.

El objetivo de este estudio fue evaluar la variación en la composición de la comunidad de peces a 2 escalas temporales y analizar la dieta de especies marinas que utilizan la laguna en alguna etapa de su ciclo de vida. El estudio se realizó en la laguna Carbonera en la costa norte de Yucatán, México. Se recolectaron peces cada 2 h con un chinchorro playero durante un ciclo de 24 h, en campañas bimestrales de diciembre de 2010 a octubre de 2011. Las variables hidrológicas registradas y la comunidad de peces se evaluaron a escala nictémera y estacional, y se observaron cambios significativos en la temperatura y la salinidad. La riqueza específica y la diversidad de peces fueron mayores durante la noche, cuando se registraron especies marinas como los armados (Orthopristis chrysoptera), las corvinas (Bairdiella chrysoura), las mojarras (Eugerres plumieri) y los roncos (Haemulon plumierii). La mayor abundancia se obtuvo durante las horas de luz debido a la presencia de cardúmenes de juveniles de sardina (Harengula clupeola) y especies residentes (Floridichthys polyommus y Fundulus persimilis). Se analizó la alimentación de 10 especies de peces marinos en estadio juvenil, y se identificaron 4 principales gremios tróficos (piscívoros, detritívoros, malacófagos y zoobentófagos). Las especies marinas en estadio juvenil de importancia comercial que utilizan la laguna Carbonera para alimentación son las lisas, las sardinas y los roncos. Por lo tanto, este sistema brinda recursos a juveniles de especies de gran importancia para la pesca artesanal, por lo que es de suma importancia elaborar estrategias de manejo para su protección y conservación.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49644248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This calcareous material may be removed from the coral skeleton by means of physical, chemical, or biological agents, with the latter being the most influential. Despite being important, bioerosion studies on coral reefs from the Pacific coast of Mexico are scarce. In this study, we determined the volume and percentage of CaCO3 removed through bioerosion from the main massive coral species, Pavona gigantea, Porites lobata, and Porites panamensis, in the Islas Marietas and Isla Isabel National Parks (Mexico). We also evaluated the effect of extrinsic (morphology, sex, and age) and intrinsic (depth and location) factors on bioerosion. The buoyant weight technique was used to estimate internal bioerosion parameters and CaCO3 skeletal density. At the species level, P. gigantea showed volume of bioerosion values of 71.31 ± 32.35 cm3 (27.28 ± 18.05% of internal bioerosion); Po. lobata, 26.60 ± 24.87 cm3 (16.87 ± 16.31%); and Po. panamensis, 29.6 ± 14.61 cm3 (31.127 ± 29.43%). At the genus level, Pavona exhibited the highest bioerosion and skeletal density values (1.61 g·cm–3). Regarding morphology, bioerosion was higher in massive corals, but regarding age, it was higher in adult colonies (10–26 years). Islas Marietas National Park showed the highest values for volume and percentage of bioerosion. The results suggest that coral reefs on the Pacific coast of central Mexico are undergoing a high degree of inconspicuous erosion by internal bioeroders and its variability is controlled by both intrinsic and extrinsic factors. If this effect continues to rise, it could threaten the long-term maintenance of coral communities, modifying the carbonate flux equilibrium and the ecological functionality of coral reef ecosystems.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71354659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The whale was sighted on 22 March 2015 and it was a solitary individual of unrecognized sex that showed ongoing diving and surfacing behavior at a site 6.3 km from the coast with depths between 20 and 24 m. Its occurrence could be related to favorable environmental and oceanographic conditions and to the potential effect of recent seismic offshore oil and gas operations in the gulf, which may impact a whale’s location and behavior.
