Abstract
    Structure and litterfall in an Avicennia germinans mangrove stand in an arid zone on the Gulf of California, México were studied. The density (4700 ha−1) and basal area (13.5 m2 ha−1) were more characteristic of a fringe-type mangrove stand, while average height (2.7 m), number of species in 0.1 ha (1), and complexity index (1.7) were closer to those of a dwarf-type mangrove. Structure is jointly influenced by a high rate of evaporation (2982 mm per year), scarce rainfall (290 mm per year, mainly in summer) and a brief period of tidal flooding (also only in the summer). Litterfall averaged 1.75 t ha−1 per year, placing it even lower than the lowest value reported so far for mangrove litterfall (2-16 t ha−1 per year). Litterfall showed a unimodal seasonal pattern, with higher values in summer. Rainfall, sea level and the ratio rainfall/evaporation explained 86% of the seasonal litterfall variability.
