Resumen del producto

Worldwide, research on benthic diatoms from mangrove systems is scarce considering the ecological importance of these coastal ecosystems. Likewise, for the Mexican NW region studies on benthic diatoms are few and recent. Consequently, a diatomological flora representative of mangrove environments has not been circumscribed, and no distribution or abundance patterns have been determined. Despite the few researches on Mexican mangrove environments, there is a highly diverse and conspicuous taxocoenoses thriving in the mangrove environment were various substrata represent ample colonizing areas. The purpose of this work is to provide an illustrated iconographic catalogue of representative diatoms from subtropical mangroves environments in NW México. The catalogue includes 520 taxa classified in 104 genera, sampled from intertidal sediments, prop roots of Rhizophora mangle and their epiphytic macroalgae, as well as tychoplankton from four mangrove systems of the Mexican NW. In the iconographic section 234 taxa are represented, including morphological variations for certain taxa.
