In this work, seasonal and diel variation of abundance and size structure of the species of mojarras (Teleostei: Gerreidae) were analyzed; as well as environmental factors influencing their variation. 19 diel cycles were made (one for month); a total of 12,500 individuals were collected that corresponding to four genera and...
Of the 138 species of bats exist in Mexico, most belong to the genus Myotis, therefore, it is considered the largest bat genus in the country. Myotis velifer, the species chosen for this study, is a hibernating microchiropteran in which although it has not been conclusively determined, it is likely...
"La Cienega Grande de Xochimilco" is part of the Ecological preservation zone “Ejidos de Xochimilco y San Gregorio Atlapulco”. It’s considered as a regulation lagoon for flood control. It’s an important area for birds associated to aquatic environments, but there are no actions for wildlife conservation. Education is one of...
Indirect methods were used to obtain behavior indicator in a mesopredator community in a semiarid and semiperturbed zone in Santo Tomás Otlaltepec, Puebla. With camera-traps the presence and activity hours of nine mesopredators were registered, finding that they have preference for nocturne activity. The fresh feces of this species were...
In the present study two different rooms within an anthropogenic building, used as shelters by the species of bats Myotis velifer and Taidarida brasiliensis, were characterized to determine whether there are differences in environmental conditions that indicate preferences in the selection of shelters by these species. This construction is located...
Se analizó la abundancia, riqueza y diversidad de la herpetofauna del Área Natural Protegida Cuenca Hidrográfica Río Necaxa (ANP - CHRN) en el Estado de Puebla, México. Se aplicó el enfoque metodológico de “ventanas” y para el análisis de la diversidad se utilizó el modelo de partición aditiva. En el...
Este trabajo se realizó con el objetivo de entender cómo es la estructura ecológica funcional de un gremio de mesodepredadores en términos del uso de los recursos alimenticio, espacial y temporal en el matorral xerófilo de Santo Tomás Otlaltepec, Puebla. En esta zona se establecieron 6 recorridos en los que...
La biogeografía estudia la distribución de los seres vivos en el espacio y el tiempo y propone hipótesis acerca de los procesos que la causaron, a partir del reconocimiento de patrones de distribución y de la identificación de áreas de endemismo compartido. El bosque mesófilo de montaña (BMM) es un...
The equatorial orientation of fruits is present in diverse cacti. In some species from the north hemisphere, have reported they produce bigger fruits and more seeds in southern branches and/or ribs. If these are more attractive for frugivores, we expect them show a preference for them in comparison with those...
