Ichthyofauna Of San Ignacio Lagoon, Baja California Sur, Mexico

General characteristics of the diet of Trachinotus paitensis (Teleostei: Carangidae) from San Ignacio Lagoon, Baja California Sur, Mexico.

The food habits of Trachinotus paitensis, in San Ignacio Lagoon B.C.S., Mexico, were investigated. We observed that T. paitensis is carnivorous, feeding mainly on benthic invertebrates (the gastropods Anachis spp., Bittium spp., and the crustacean larvae). We concluded that T. paitensis is an opportunist predator that impacts mainly on epibenthic invertebrates.

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...

The Degeneration of Cardon Populations in Baja California Sur, Mexico

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 ...
