“…Sphiggurus mexicanus es una especie considerada rara. Su biología es poco conocida y se le ubica en la categoría de amenazada, según la NOM-059-SEMARNAT-2010 (SEMARNAT 2010), y en la categoría de preocupación menor (Least concern) de la UICN (Pino et al 2008), debido a sus hábitos arborícolas y a su dependencia de bosques tropicales húmedos, los cuales están desapareciendo rápidamente (Lorenzo et al 2014). Los datos aquí presentados contribuyen a la ubicación de poblaciones de la especie en el estado, lo que permitirá realizar estudios que aporten mayor información sobre la biología de esta especie, y resultan críticos para desarrollar estrategias de conservación.…”

“…Recientemente se reportó su presencia en los bosques templados de pino y pino encino (a altitudes de 770 a 920 m) del suroeste de Michoacán (Monterrubio-Rico et al 2010). Los altos índices de pérdida y fragmentación de su hábitat, así como la cacería y el escaso estudio sobre esta especie en particular, no han permitido conocer más ampliamente su ecología y distribución (Lira et al 2005;López et al 2009;Lorenzo et al 2014).…”

“…Para el estado de Oaxaca se ha documentado la presencia de S. mexicanus en la región de la planicie costera del Golfo, distrito de Tuxtepec; en la región de la cañada, distrito de Cuicatlán; en la planicie costera del Pacífico, distrito de Jamiltepec, y en el Istmo de Tehuantepec, distritos de Juchitán y Tehuantepec. Los registros anteriores lo sitúan en altitudes entre 0 y 500 m. Ocupa dunas costeras, bosque tropical perennifolio, bosque tropical caducifolio, pastizales, vegetación secundaria y cultivos (Goodwin 1969;Hall 1981; Navarro y Meave 1998; Briones-Salas y Sánchez-Cordero 2004;Lira et al 2005;CONABIO 2010a;Voss 2011;Lorenzo et al 2014).…”

The tropical porcupine, Sphiggurus mexicanus is distributed from west Panamá and Costa Rica to Michoacán on the Pacific versant and San Luis Potosí on the Gulf of Mexico basin. It dwells in tropical and semitropical dry forests, at altitudes from 0 to 3,200 m; it was recently recorded at temperate pine and pine-oak forests in Michoacán. In Oaxaca this species had been recorded only at Gulf of Mexico coastal plain, Pacific coastal plain and Isthmus of Tehuantepec, at low elevations from 0 to 500 m, and inhabiting costal dunes, tropical evergreen and deciduous forests, grasslands, farmland and secondary vegetation. The goal of this paper is to report new data on the distribution of the tropical porcupine in Oaxaca, México. Methods: Five records are based on a voucher specimen and direct sight of individuals or remains found along field trips. A sixth record was obtained with Camera traps. Results: We report a specimen of S. mexicanus found dead on the road near Colonia Cuauhtémoc, this record lies within the known distribution for the species. We also report five noteworthy records for the Mexican tree porcupine, three at Sierra Norte and two at Cuicatlán-Tehuacán Valley regions, all within cloud forests, at altitudes from 1,673 to 2,668 m. Discussion and conclusions: The three records at Sierra Norte expand the geographical range for this species 34 km to the southwest, from San Juan Petlapa, the closest known locality. These records along with the two from Cuicatlán valley are the first records for the tropical porcupine within cloud forests in Oaxaca and at higher altitudes than those previously reported. The record of a small immature female implies that the species is actually breeding within this type of forest in Oaxaca. These five records are noteworthy as they expand the known geographical and ecological distribution of the Mexican tree porcupine in Oaxaca. Distributional data are fundamental to the species biology and critical to conservation strategies.

Notes on bat movements in a fragmented landscape in the Tehuantepec Isthmus, Mexico

Several studies have observed that bat species respond differently to landscape changes and that individuals tend to expand their home range when the habitat is not optimal. Tropical dry forest in the Isthmus of Tehuantepec, Mexico, shows a high habitat loss and fragmentation by anthropogenic causes. However, how bats use this fragmented landscape is unknown. Therefore, the aim of this study was to describe the temporal and spatial movements of bats fitted with radio transmitters in a fragmented region of the Isthmus of Tehuantepec. In July 2011, six bats belonging to three species were captured: an adult female of Artibeus lituratus, a juvenile female of A. jamaicensis, an adult male of Leptonycteris yerbabuenae (Family Phyllostomidae), and three adult females of Pteronotus parnellii (Family Mormoopidae) were fitted with a radio transmitter. Bats were monitored during night (18:00 to 06:00 h) from fixed stations for 17 days. The activity was obtained by quantifying the frequency of bearings in intervals of one hour. Simultaneous bearings were triangulated for locations, which were exported to a vector map where type of land use and vegetation was determined. The home range was calculated using two techniques: minimum convex polygon and fixed Kernel. A total of 75 bearings corresponding to an adult female of A. lituratus (n = 36, 48.0 %), three adults females of P. parnellii (n = 30, 40.0 %), and an adult male of L. yerbabuenae (n = 8; 10.6 %) were obtained. A juvenile female of A. jamaicensis was located on one occasion (1.3 %). Female of A. lituratus showed activity between 19:00 and 23:00 h and between 24:00 and 05:00 h, with a peak between 03:00 y 04:00 h. This bat widely used the area with preference to riparian vegetation. Based on their locations, a home range (Kernel 95 %) of 8,394 hectares and a minimum convex polygon of 2,587 hectares were estimated. The male of L. yerbabuenae showed activity only between 22:00 and 02:00 h and their locations were on agriculture land (n = 2). The observed activity of P. parnellii began at 20:00 h, it was increased to at 22:00 h (one activity peak between 01:00 and 3:00 h) and gradually declined until 06:00 h. The three females of P. parnellii were located in agricultural land (n = 4) and cultivated pasture (n = 1). The home range of A. lituratus observed in the present study is the largest reported for phyllostomid bats, possibly in response to landscape condition. Activity and locations of three females of P. parnellii and a male of L. yerbabuenae suggest that they occasionally use the study area in their way to more productive areas.Se ha observado que las especies de murciélagos responden de manera diferencial a los cambios en el paisaje y que los individuos tienden a ampliar su ámbito hogareño cuando el hábitat no es óptimo. Las selvas secas de la Planicie costera del Istmo de Tehuantepec, en México, presentan una alta pérdida y fragmentación por causas humanas. Sin embargo, se desconoce cómo los murciélagos usan este paisaje fragmentado. Por lo anterior, el objeti...

“…Es posible que los individuos se muevan entre fragmentos de bosque a través de la matriz de áreas agrícolas, probablemente en busca de recursos alimenticios; esta situación los hace propensos a la cacería humana o atropellamientos (Monje-Nájera 2018), como en el caso de uno de los registros de oso hormiguero. Dado que ambas especies parecen tolerar ambientes antropizados, consideramos que la conectividad del hábitat mediante corredores es una de las medidas de manejo que deben ser impulsadas la región para la preservación de estas y otras especies (Lorenzo et al 2014).…”

Presentamos registros notables de tlacuache dorado (Caluromys derbianus), oso hormiguero (Tamandua mexicana) y puerco espín (Coendou mexicanus), tres especies crípticas, de hábitos arborícolas consideradas amenazadas en México, cuya presencia en Oaxaca es histórica o escasa. El registro de tlacuache dorado se obtuvo a través de fototrampeo y los registros de puerco espín y oso hormiguero por medio de reportes de habitantes locales. El tlacuache dorado fue registrado en un fragmento de bosque tropical perennifolio, mientras que los registros de las otras dos especies ocurrieron en áreas agrícolas, pero cerca (<3 km) de parches de vegetación secundaria de bosque tropical perennifolio cuyas áreas fueron iguales o mayores 0.97 km2. Estos registros incrementan el conocimiento de la presencia de estas especies en el norte de Oaxaca. Los registros muestran la tolerancia del oso hormiguero y el puerco espín a paisajes antropizados, y ponen en evidencia el tipo de riesgos que pueden enfrentar por atropellamientos y captura.
