Resumen:

The native crayfish Procambarus acanthophorus (Villalobos, 1948) is geographically distributed in Southeast Mexico, in the states Veracruz, Oaxaca, and Chiapas. This crayfish inhabits freshwater ecosystems such as creeks, lagoons, and wetlands. Procambarus acanthophorus builds and inhabits complex burrows during dry periods and lives in open water during rainy seasons when wetland flooding occurs. These annual environmental variations appear to be predicted by this species to determine their population dynamics, possibly by detection of cyclic changes in the water level or variations in the water temperature. Under laboratory conditions, this crayfish maintains its ability to dig burrows and build chimneys, permitting us to study the influence exerted by sediment availability on behavioral and physiological processes. P. acanthophorus is consumed and could be considered as an economic resource. In this regard, when this crayfish emerges into open water, persons living in the wetland catch it with artisanal traps and sell it. Thus, in addition to modification of the ecosystem through the construction of roads, which reduces the connection between the river and the floodplain, the abundance of this species has diminished, at least in some localities, suggesting the need to establish a conservation strategy permitting the sustainable management of this resource. © 2016 Nova Science Publishers, Inc.
