Se presentan los resultados de un año de estudio de individuos pertenecientes a las familias de artrópodos presentes en 21 viviendas de Puerto Vallarta, México. Con el uso de trampas adhesivas se capturaron 25 197 ejemplares. Se determinaron 122 familias en 31 órdenes. Sólo cinco familias agruparon el 76.45% de la abundancia observada y los valores más altos de los índices de infestación de viviendas a lo largo del año: Entomobryidae (9.04%; 100%), Psyllopsocidae (10.10%; 95.23%), Liposcelididae (8.11%; 100%), Formicidae (33.58%; 100%) y Phoridae (15.42%; 100%).

The Trans-Mexican Volcanic Belt (TMVB) in its western section possesses a high biodiversity, resulting from its environmental heterogeneity. However, this biological richness is threatened by diverse anthropogenic pressures, such as deforestation and land use change. With the objective of evaluating the taxonomic diversity of birds in the western TMVB, this study was carried out in two localities of Jalisco: Sierra de Quila Flora and Fauna Protection Area and a sustainable avocado production zone in Zapotlán el Grande. Sampling was carried out in different vegetation types during the years 2021 to 2024, using mist nets and point counts. To evaluate taxonomic diversity, the analysis of taxonomic distinctness was employed. A total of 202 bird species were recorded, where it was observed that the most important taxonomic unit was the order level, with Passeriformes being the most diverse o...
