The municipality of Los Cabos, Mexico, has been the most affected in the state of Baja California Sur by these hazards due to its location on the southern tip of the peninsula, being exposed with approximately 192 km of coastline; it is an environmental heritage that has made the area a primary tourist attraction in Mexico, which has caused a rapid growth in population with little knowledge about cyclone activity. In addition, there is limited knowledge regarding social indicators that measure vulnerability due to tropical cyclones. Based on the above, the objective of this study was to capture community perceptions about vulnerability related to tropical cyclones and to compare the results with real impacts and their index of socioenvironmental vulnerability, which includes indicators of exposure, sensitivity, and adaptive capacity, to provide useful information to form strategies to mitigate risk....

The aim of the present study was to determine the community structure, in particular dominance of fish species associated to soft bottoms in the lagoon of La Paz. Six bimonthly samplings were carried out in seven localities from November 2016 to September 2017 and physicochemical parameters were recorded. Analysis of temperature showed differences between two marked seasons, warm and cold. Species richness showed differences between months and localities. Shannon-Weaver index and Pielou's evenness showed significant differences only between months. Simpson's index suggests a high diversity. According to the BVI, 15 species from the families Haemulidae, Sciaenidae and Gerreidae, were the most biologically important. Zoogeographic affinity analysis showed that 58% of the species prefer the Province of Cortez. Dominant species recorded in this study play a key role in soft-bottom systems like the lagoon of La Paz.

The trajectories of these could separate in four groups. The magnitude of the elevations of level or storm surges generated by these phenomenons could obtain subtracting of the historical series of the level of the sea, obtained of the tide gage installed in the La Paz Bay and Cabo San Lucas, the forecast obtained upon applying the harmonic analysis of Godin. In the analyzed series elevations are observed that they reach 1 m in the La Paz Bay, associate with the hurricane 10 in September of 1959 and 60 cm in Cabo San Lucas, associate with the Fausto hurricane in September of 1996. In order to examine variability of long shore currents the Wes Implicit Flooding Model (WIFM), based on the shallow water equations, was applied. Surface wind fields, imposed as a surface boundary c...

Baja California Sur, a state known as a relevant ecological and tourist region, includes destinations such as Cabo San Lucas and La Paz, impacted yearly by tropical cyclones, so it is important to design contingency plans and provide available information to the residents. Los Cabos municipality has the highest population growth rate and its inhabitants are more susceptible to adverse events; despite this, there were no indicators of social and ecological vulnerability to risk effects of tropical cyclones. The objective of this research is to calculate the socio-environmental vulnerability of households through an index to identify risk factors. We have obtained a classification according to levels of vulnerability, and the results have shown that 74% of the households are high on the v...

During low tide, rocky pools are exposed to air for several hours throughout the day, and environmental conditions such as temperature and salinity are highly variable. Fish communities that inhabit these tide pools are also exposed to environmental variability; therefore it is important to look at fish community structure in relation to important environmental factors such as temperature, salinity and dissolved oxygen on tide pools during spring tides, time of greater exposure to air. Therefore, the aim of the present study was to analyze the variation of the taxonomic distinctness of intertidal fish communities considering temperature, salinity and dissolved oxygen of the water that remains trapped in the tide pools during low tide. Visual census surveys were carried out monthly, from January to December 2015, in the intertidal zone of El Faro during spring tides on full moon days, when fluctuations of environmental variables are significant. Total extension of the census surveys was 156 × 5 m (780 m 2). A total of 145 tide pools were sampled and divided in three groups (small, medium and large) according to size and depths that ranged from 20 to 45 cm. Temperature, salinity and dissolved oxygen fluctuate throughout the year of study. Thermal difference between open ocean and tide pools ranged from 3.5˚C to 4.5˚C. A total of 3757 organisms from 22 species, 12 families, four orders and one class were recorded. When comparing taxonomic distinctness and average taxonomic distinctness between months and tide pools of different sizes, values fell within the confidence intervals in the tunnel and were located close to the mean.

Because of its geographical location, it is considered to be a part of the Californian province temperate region. There have been several studies of the fish fauna present in the lagoons of Baja California Sur, however, the information collected so far is not enough to provide good management and conservation of the fish fauna of this lagoon. This study established the zoogeographic affinities of fish species associated to soft bottoms registered in San Ignacio Lagoon B.C.S. Six samplings were conducted at 11 sites in the lagoon, from April 2013 to April 2014; an experimental trawl was used and the physicochemical parameters were obtained at each sampling. A total of 2887 organisms from 26 families, 38 genera and 46 species of fishes were collected, the largest number of species were from the Haemulidae and Serranidae families. The zoogeographic affinities correspond to 28% Californian Province, 4% Cortez Province, 7% Mexican Province, 41% Panamic Province, 18% Eastern Pacific and 2% Circumtropical.
