We evaluated the forest structure, pore water salinity, geochemical characteristics, grain-size distribution and sediment accumulation rates (SAR) in 15 mangrove sites along the San Pedro Mezquital River, one of the major sources of fresh water supply to the Marismas Nacionales System. Sediments were sandy-silty with high organic matter content (5....

The San Pedro Mezquital River is the seventh largest river in Mexico, and flows through the Sierra Madre Occidental into the Marismas Nacionales Biosphere Reserve, on the coast of the state of Nayarit. The present study is to conform a systematic checklist of fishes in the lower basin of the San Pedro Mezquital River. In total, 52 species were coll...

The estuarine system of Marismas Nacionales (Pacific coast of Mexico) is a Biosphere Reserve that is considered to be the most extensive mangrove region in the American Pacific, and an important region for artisanal fisheries since prehispanic times. Significant hydrological changes occurred in this region after 1976 when an artificial channel was...

Marismas Nacionales is a marine flood plain system located in the pacific coast of Mexico considered the most extensive mangrove region of the American Pacific. This region is an important region for fisheries since prehispanic times with high biodiversity and an important wintering region for migratory birds from Canada and USA. Significant hydrol...

Hurricane Rosa inflicted considerable damage to the mangrove forests of the Teacapán-Agua Brava Lagoon System of Mexico. Data collected from five transects indicate an overall reduction in stem density and basal area of approximately 31 and 51 percent respectively. Of the 1390 trees examined, only 44% remained well vegetated and 28% were found with...

To evaluate the accounts of local fishermen, Landsat TM images (1986, 1993, 1999) were examined to assess potential losses in the mangrove forests of the Teacapán-Agua Brava lagoon system, Mexico. A binary change mask derived from image differencing of a band 4/3 ratio was employed to calculate any changes within this forested wetland. The results...
