The effect of tidal exclusion on salt marsh vegetation in Baja California, México

Abstract: Changes in salt marsh vegetation were analyzed over a two-year period (November 1984–November 1986) following the construction of a dike in the southwest corner of Punta Banda Estuary, Baja California, Mexico. Changes included: increased interstitial soil salinity, reduced soil moisture, increased mortality of Spartina foliosa and decreased middle marsh species diversity due to the elimination of annual and short-lived species. The sea-side edge of the middle marsh shifted its boundary to a lower elevation. By the end of 1986, dominant species were Salicornia virginica, Batis maritima and Frankenia grandifolia. By October 1988, only a few patches of S. foliosa persisted at the water edge, and it appeared that the community was not yet stable. The potential future of the estuary is evaluated.

Coral communities and reefs from Guerrero, Southern Mexican Pacific

Abstract: Corals in the Eastern Pacific extend south from the Gulf of California to Ecuador and oceanic Chile, and west from Colombia to Clipperton Atoll. Nevertheless, large stretches of the Mexican Pacific remain fundamentally unstudied. Therefore, to assess the current conditions of coral communities, a coastal fringe ∼300 km long (17°40′ N, 101°39′ W to 16°46′ N, 99°49′ W) was surveyed within the Southern Mexican Pacific, between 2005 and 2009. Fifteen stony coral species were identified at 13 coral communities and six Pocillopora-dominated fringing reefs, with Pocillopora verrucosa and Pocillopora damicornis the primary contributing taxa. Reef development was identified in embayments or behind rocks or islands that offered shelter from northern and northwestern winds. Observations of Pocillopora effusus, Pocillopora inflata, Porites lobata, Pavona clavus, and Pavona varians expanded the species known geographic ranges by several degrees of latitude, suggesting reef building fauna comprised a mixture of widespread and relatively rare Eastern Pacific corals. Results indicated greater live coral cover in the Ixtapa-Zihuatanejo area (15–73%) than in the Acapulco localities, which had high algal dominance; the reefs in the latter region exhibited high erosion. Regional differences are likely the result of long-standing anthropogenic pressures around Acapulco since 1950, when it became an important tourist destination. This paper is the first detailed report of ecologically stressed corals and coral reefs from the state of Guerrero on the Mexican Southern Pacific coast.
