Distribution of the acoustic occurrence of dolphins during the summers 2011 to 2015 in the Upper Gulf of California, Mexico [PDF]
Baseline knowledge of spatial and temporal distribution patterns is essential for cetacean management and conservation. Such knowledge is particularly important in areas where gillnet fishing occurs, as the Upper Gulf of California, which increases the ...

Indirect effects of conservation policies on the coupled human-natural ecosystem of the upper Gulf of California. [PDF]
High bycatch of non-target species and species of conservation concern often drives the implementation of fisheries policies. However, species- or fishery-specific policies may lead to indirect consequences, positive or negative, for other species or ...

Stock Reduction Analysis of Bigeye Croaker Micropogonias megalops in the Upper Gulf of California, Mexico [PDF]
A stock reduction analysis (SRA) of bigeye croaker Micropogonias megalops was performed based on commercial catch data. SRA solutions were restricted to a 2011 bigeye croaker stock biomass estimate of 14,412 t.

The influence of Colorado River flows on the upper Gulf of California fisheries economy
Abstract This analysis explores the influence of Colorado River flows into the Upper Gulf of California on fisheries productivity. Working with available time series data for the region, a series of plausible relationships are modeled between river flows and fisheries catch, focusing on the top commercial species, shrimp and gulf corvina.

Evolution of the vaquita/totoaba socio‐ecological system in the Upper Gulf of California, Mexico
The Upper Gulf of California (UGC) hosts a rich marine biodiversity. Complex climatic processes generate high biological productivity enabling the use of resources in a complex socio‐ecological processes (SEPs). Through a literature review, evolution and

Applying SPOT Images to Study the Colorado River Effects on the Upper Gulf of California [PDF]
Sediment discharges from rivers play a key role in downstream ecosystems, both for ecosystem morphology (e.g., deltas) and productivity. However, the construction of dams and river regulation dramatically alter sediment transport. Currently, the Colorado
