The Degeneration of Cardon Populations in Baja California Sur, Mexico

Population dynamics of Megapitaria squalida (Bivalvia: Veneridae) at Magdalena Bay, Baja California Sur, Mexico.

The population dynamics of an intertidal population of Megapitaria squalida was studied from September 2002 to February 2003 in Bahia Magdalena, Mexico. To obtain information about the artisanal and recreational fishery of M. squalida, local fishermen at different parts of the bay were interviewed. Clam densities were determined at one unexploited and two exploited sites along perpendicular tra...

Identifying recharge from tropical cyclonic storms, Baja California Sur, Mexico.

Groundwater in the Todos Santos watershed in southern Baja California, and throughout the peninsula south of latitude 28°N, has values of (δ18 O‰, δD‰) ranging between (-8.3, -57) and (-10.9, -78). Such negative values are uncharacteristic of the site latitude near the sea level. Altitude effects do not explain the isotope data. Tropical depressions originating along the Pacific coast of North ...

Raptors as Indicators of Environmental Change in the Scrub Habitat of Baja California Sur, Mexico

“Indicator” species of natural habitat quality are potentially useful tools for managers of biodiversity (Rohlf 1991). Predators are often considered indicators because they are at the top of food webs and need wide home-range areas to function. Predators play an important role in ecosystems because they can determine the community structure patterns of their prey (Menge et al. 1994). In additi...

Characteristics and methanogenesis of the Balandra lagoon mangrove soils, Baja California Sur, Mexico

Soil characteristics and methanogenesis were investigated in Fluvisols of the Balandra lagoon mangrove in Baja California, Mexico in March/April 1995. The grain size distribution was dominated by the silt fraction (54-92%), sand and clay contents were 6-44% and 0-19%, respectively. Bulk density was 0.6-1.5 g cm, the water content 290-690 ml 1 and the air content 38-200 ml 1. The soils always sh...
