we examined the diet and trophic level of sphyrna lewini in the gulf of california (gc) during 2001 and in the gulf of tehuantepec (gt) during 2005 using data from stomach content and stable isotope analysis of δ15n and δ13c. s. lewini diet was represented by pelagic and benthic prey species where the most important in weight was scomber japonicus (27.70±4.54%) in gc, while in gt it was auxis s...

The bigeye thresher shark Alopias supeciliosus is a large epipelagic and mesopelagic species, it has wide distribution in the Atlantic. However, its record Gulf of Mexico sporadic. A single adult female A. superciliosus, measuring 360 cm total length about weight 165 kg, was caught by artisanal fishers Salinas Roca Partida, Veracruz, Mexico, on July 14, 2020. This study reports first occurrence...

Anthracnose, which is caused by the fungus Colletotrichium gloeosporides, is a widespread and destructive disease on container-grown azalea. This disease is especially common in container nurseries, which are located near the Gulf of Mexico in Florida, Alabama, Mississippi, Louisiana, and Texas. Anthracnose is a hot, wet weather disease. This year, frequent showers and daily cloud cover through...

The red tide dinoflagellate Karenia brevis (Davis) G. Hansen and Moestrup is noted for causing mass mortalities of marine organisms in the Gulf of Mexico. Most research has focused on culture isolates from the eastern Gulf of Mexico. In this investigation, we examine the effects of light, temperature and salinity on the growth rate of K. brevis from the western Gulf of Mexico. Growth rates of K...

Sequence analysis was performed on viral RNA isolated from bottlenose dolphins (Tursiops truncatus) that died during two chronologically and geographically separate epizootics in North America. Both dolphin morbillivirus (DMV) and porpoise morbil-livirus (PMV) were detected in bottlenose dolphins that died during the 1987 U.S. Atlantic coast epizootic. Our results indicate not only that these v...

The environment is currently undergoing changes at both global (e.g., climate change) and local (e.g., tourism, pollution, habitat modification) scales that have the capacity to affect the viability of animal and plant populations. Many of these changes, such as human disturbance, have an anthropogenic origin and therefore may be mitigated by management action. To do so requires an understandin...

Gulf surges are transient disturbances that propagate along the Gulf of California (GoC) from south to north, transporting cool moist air toward the deserts of northwest Mexico and the southwest United States during the North American monsoon. They have been shown to modulate precipitation and have been linked to severe weather and flooding in northern Mexico and the southwest United States. Th...

Summer hypoxia in the bottom waters of the northern Gulf of Mexico has received considerable scientific and policy attention because of potential ecological and economic impacts from this very large zone of low oxygen and because of the implications for management within the massive Mississippi River watershed. An assessment of its causes and consequences concluded that the almost 3-fold increa...
