Carbon Stocks of Tropical Coastal Wetlands within the Karstic Landscape of the Mexican Caribbean
Coastal wetlands within the Sian Ka'an Biosphere Reserve (SKBR) in Mexico's Yucatan Peninsula store significant amounts of carbon, with tall mangroves holding the highest stocks at 987±338 Mg ha⁻¹. Soil carbon constitutes 78-99% of these stocks, indicating its critical role in ecosystem carbon storage. The study found that lower salinity and higher phosphorus levels in soils correlate with greater carbon sequestration potential, suggesting phosphorus limitation. Across the 172,176-ha reserve, coastal wetlands may store between 43.2 to 58.0 million Mg of carbon, underscoring their importance as a climate mitigation strategy. Researchers quantified ecosystem carbon stocks by measuring above and belowground biomass, downed wood, soil carbon, nitrogen, phosphorus, and interstitial salinity at nine sites within SKBR.
Estimates of exploitation rates of the spiny lobster fishery forPanulirus argusfrom tagging within the Bahía Espíritu Santo ‘Sian Ka'an’ Biosphere Reserve, Mexican Caribbean
A study of the Caribbean spiny lobster (Panulirus argus) fishery within Sian Ka'an Biosphere Reserve, Mexico, reveals high exploitation rates exceeding 0.94, driven by intensive fishing in shallow waters (≤20 m) due to gear restrictions. The research used a modified Brownie model to analyze tag recovery data from the 2010/2011 season, accounting for tag retention and reporting biases. Independent aquaria trials and fisher interviews refined estimates of mortality and catchability. Findings suggest that the 'casita/campo' system, which relies on fast-growing juveniles, sustains stable landings by enabling seasonal replenishment, despite high exploitation pressures.
