Title A name given to the resource La ecología alimentaria del pez endémico Girardinichthys multiradiatus (Cyprinidontiformes: Goodeidae), en el Parque Nacional Lagunas de Zempoala, México Creator An entity primarily responsible for making the resource Patricia Trujillo-Jiménez, Efrén Espinosa de los Monteros Viveros Description An account of the resource Girardinichthys multiradiatus, conocido comúnmente como 'mexcalpique' un pequeño pez endémico de la cuenca del río Lerma, cuya presencia en el parque Nacional Lagunas de Zempoala, sugiere una antigua conexión entre estos lagos y la cuenca. El área de distribución actual en la porción del valle de México y Toluca se ha visto reducida, por lo que este parque representa un refugio para la especie. Sin embargo, se conoce poco de la biología del mexcalpique. Presentamos datos sobre su dieta y hábitos alimentarios. El estudio se realizó en el Lago Acoyotongo del Parque Nacional Lagunas de Zempoala mediante muestreos estacionales. La identificación del contenido estomacal (97 ejemplares) se llevó hasta el taxón más específico posible. Para la cuantificación se utilizaron los métodos numérico y frecuencia de aparición. La dieta general de esta especie se encuentra constituida por doce componentes alimenticios, de los cuales once son de origen animal. Himenópteros, colémbolos y quironómidos fueron los que presentaron los mayores porcentajes de ingestión y preferencia. Esta es una especie carnívora con tendencias insectívorasThe feeding ecology of the endemic fish Girardinichthys multiradiatus (Cyprinidontiformes: Goodeidae) in Lagunas of Zempoala National Park, Mexico. Girardinichthys multiradiatus, locally known as 'mexcalpique', is a small endemic fish of the Lerma river basin. Its presence in lakes (Zempoala) suggests a long-standing connection between these lakes and the river basin. The current range of this species in the Mexico and Toluca valley appears to have been reduced, making this park a refuge for the species. Nevertheless, little is known about its biology. We studied its diet and feeding habits in Acoyotongo Lake, Lagunas de Zempoala National Park (19°01’30'-19°06’ N, 99°16’20'-99°21’ W) where seasonal collections were carried out. The gut contents of 97 specimens were identified to the most specific taxonomic category possible and analyzed with numeric and frequency of occurrence methods. The general diet of this species consists of twelve dietary components, eleven of which are of animal origin. Hymenopterans, springtails and chironomids represented the highest percentage of ingestion and preference. G. multiradiatus is as a carnivorous species with entomophagous tendencies. Rev. Biol.
