Mammals from the Tarascan Plateau, Michoacán, México.

Abstract

Resumen: Se examinaron 568 ejemplares de mamíferos nativos de 49 especies, procedentes de 49 localidades de la Meseta Tarasca o Sierra Purépecha del Estado de Michoacán, México. Las especies encontradas en esta región del Eje Volcánico Transversal incluyen 1 marsupial, 2 insectívoros, 17 quirópteros, 2 carnívoros, 24 roedores y 1 lagomorfo. Para calcular la diversidad de especies en los cuatro hábitats muestreados, se utilizaron las 2 especies de insectívoros y 21 de roedores. De mayor a menor diversidad, en el bosque de pino-encino se recolectaron 201 individuos de 15 especies (H’ = 2.49), en el bosque tropical caducifolio 142 de 15 especies (H’ = 2.43), en el bosque de oyamel 92 individuos de 10 especies (H’ = 2.01) y en las áreas de ecotono 52 individuos de cuatro especies (H’ = 1.15). El registro de Hylonycteris underwoodi es el primero para las partes altas del Estado de Michoacán. Abstract: We examined 568 specimens of native mammals belonging to 47 species from 49 localities of the Tarascan Plateau or Sierra Purépecha mountain range in the State of Michoacán, México. Species composition of this enclave in the Transvolcanic Belt is 1 marsupial, 2 insectivores, 17 bats, 2 carnivores, 24 rodents, and 1 lagomorph. To calculate the species diversity according to the four sampled habitats, only the 2 insectivore and 21 rodent species were included. From higher to lower diversity values, we found 201 specimens from 15 species in pine-oak forest (H’ = 2.49), 142 from 15 species in tropical deciduous forest (H’ = 2.43), 92 specimens belonging to 10 species fir forest (H’ = 2.01), and 52 from four species in an ecotonal area (H’ =1.15). Hylonycteris underwoodi is the first record for the highlands from the State of Michoacan. Key words: Mammals, distribution, diversity, Tarascan Plateau, Michoacán.

Role of Pleistocene climatic oscillations on genetic differentiation and evolutionary history of the Transvolcanic deer mouse Peromyscus hylocetes (Rodentia: Cricetidae) throughout the Mexican central highlands

“…The occurrences of P . hylocetes were obtained from fieldwork, museum specimens, and published studies (Amman et al, 2006; León‐Tapia et al, 2020; Orduña Trejo et al, 1999; Steppan & Schenk, 2017; Sullivan et al, 1997; Vázquez et al, 2000, 2004). Additionally, a second set of occurrences were downloaded from the Global Biodiversity Information Facility (GBIF; http://www.gbif.org/) and filtered by museum specimens.…”

Chemical Composition, Antioxidant Properties, and Antibacterial Activity of Essential Oils of Satureja macrostema (Moc. and Sessé ex Benth.) Briq

“…The sampling area was located on the Purepecha plateau, with a height of 1700–3200 masl and cold weather almost all year round, with a temperature of 12–18 °C. The predominant vegetation consists of deciduous tropical forests, mainly including species of pines, oaks, and firs with dark or reddish soils formed from volcanic ash [ 36 ]. The leaves were detached from the plants manually and dried in a shady environment to avoid any alterations caused by solar radiation.…”
