- Population dynamics of the crayfish Cambarellus chapalanus from the San Juan Cosalá Mountain Range, Jalisco, Mexico Ignacio Cáceres Esmeralda Citlali Ibarra-García Fabián Alejandro Rodríguez-Zaragoza Manuel Ayón-Parente Biología growth mortality Cambaridae production productivity Cambarellus chapalanus is an endemic species of the area around Lake Chapala in Mexico and knowledge about its biology and ecology is scarce. Its population dynamics were evaluated based on individual growth, mortality, production, and productivity. For this, individuals were collected between November 2011 and October 2012, in ponds located in the Sierra San Juan Cosalá, Jalisco, Mexico. The abiotic variables of ponds (depth, temperature, pH, precipitation, and evaporation) presented significant variations during the study. Abundance was similar throughout the year but was related to an increase in temperature and evaporation of ponds. Furthermore, males were more abundant than females. Growth was fast and oscillatory with slow phases in rainy periods. Mortality was high and started at medium sizes; however, high somatic production also generated high population productivity. In general, the parameters of C. chapalanus showed normal patterns for a natural population; however, were strongly influenced by temperature and pond volume, probably because it is an isolated population in Sierra San Juan Cosalá. 2022 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42575514076 https://www.redalyc.org/journal/425/42575514076/ https://www.redalyc.org/journal/425/42575514076/html/ https://www.redalyc.org/journal/425/42575514076/42575514076.epub https://www.redalyc.org/journal/425/42575514076/movil 10.22201/ib.20078706e.2022.93.4835 en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Vol.93
