The mangroves of arid areas are subject to natural pressure due to the absence of fresh water contributors as it happens in mangroves of humid tropical areas. This factor determines the exuberance of the mangrove, making it shorter and with less extensive coverage than those located in humid tropical regions. Considering this scenario, the mangroves of arid areas grow possibly with the food of underground fresh water. This could be the reason why they are located at the end of the rills of rainfall drainage, where due to the topography of the area, it is possible to find underground water flow ...

The environmental quality of the coastal area is a parameter that should be known to establish management actions to assure constant environmental health of the coastal ecosystems. The methods to measure environmental quality are efficient tools to determine, monitor, and establish the trend of environmental quality to be ready to define management or correction strategies in real time ...

This research implies studies in hydrodynamics and coastal modeling by performing the analysis of different dynamic agents that have a bearing on the coast (wind, swell, tide, current). It will allow establishing sedimentary transport and hydrodynamics, as well as obtaining basic information to perform modeling and predict coastal changes at short, medium, and long term, both for low natural conditions and for induced conditions ...

Knowledge of population dynamics and community structure of the species that live in coastal ecosystems contributes to understand ecological aspects, and it is also useful to indicate environmental conditions of the ecosystems....

The State Contingency Committee for the Control of Marine Biotoxins (Comité Estatal de Contingencias para el Control de Biotoxinas Marinas de Baja California Sur) found the presence of Pyrodinium bahamense var. bahamense potentially toxic dinoflagellata south of Isla San José, Baja California Sur while performing work in the summer of 2006.This finding represents the first record for the coasts of Baja California Sur. Considering that this species has caused several public health problems and losses in economic activities that amount to millions, this research is directed to go in depth in their biology and ecotoxicology to estimate potential impacts in the Gulf of California ...

Natural and human effects in coastal systems can favor important changes in phytoplankton communities. Contributions of macronutrients (nitrogen and phosphorous) and their role in the blooming of harmful species are already known, which is why we foresee that the frequency of these events might favor important consequences in environmental health. Gymnodinium catenatum is a dinoflagellata responsible for the majority of the harmful events in the Mexican Pacific. There are also records of this species in the Bay of La Paz, but its abundance is comparatively smaller ...

Developing methods to control blooming and persistence of red tides is a socio-economic priority mainly in those regions with a vocation for aquaculture and recreational tourism activities. The increase in number of events, in species that spread massively, and in duration, have moved researchers to propose mitigation and control methods, and toxicity implications of these phenomena.  It is worth highlighting that there are no studies in this respect in  Mexico, and the information generated will be very useful for the different sectors involved in red tide events ...
