| description | Natalus stramineus is a cave-dwelling bat broadly spread in Mexico but with scarce information about its natural history. In this work, we reported the associated bat species and roosting sites of N. stramineus in Mexico. Also we observed roosting habits and recorded monthly air temperature and relative humidity throughout one year in a roost of this bat, located in the state of Colima, Mexico. It has been found in 108 roosting sites most of which are caves and mines. These roosts were located in a wide range of elevations, vegetation and climates, however most were located below 400 m asl, in tropical deciduous forest and hot-subhumid conditions. We were unable to find this species in some previously recorded caves. In El Salitre Cave, temperature and relative humidity in their roosting sites were stable throughout the year. The former variable fluctuates from 25.8 to 26.9°C and the latter variable from 92.1 to 100%. Individuals of N. stramineus usually hang in the lower parts of walls and rocky ceilings, occupying cavities and crevices occasionally. They hang individually without contact to each other, keeping a distance of 5-50 cm between themselves. Forty-five bat species have been found associated with this natalid, but more frequently Pteronotus parnellii, Mormoops megalophylla, Glossophaga soricina y Desmodus rotundus. This bat prefers to occupy warm and humid parts of the roosts, because these conditions are ideal to conserve the body heat and to maintain their wings in good conditions. Its great tendency to be associated with mormopids and some phyllostomids is explained partly by their similar microclimatic requirements in their refuges, as well as by the thermal benefits associated with clustering in colonies. N. stramineus depends heavily on hot caves for their survivorship and occupies mines with similar microclimatic conditions in an opportunistic way. |

Natalus stramineus es un murciélago cavernícola ampliamente extendido en México del que poco se sabe sobre su historia natural. En el presente trabajo, se reportan los refugios y las especies asociadas a este murciélago en México. Además se reporta la variación mensual de la temperatura ambiente y humedad relativa en una cueva donde se alberga, localizada en Colima, México, donde también se observaron sus hábitos de percha. Este murciélago ha sido encontrado en 108 refugios que en su gran mayoría son cuevas y minas, los cuales se localizaron en un amplio intervalo de altitud, tipos de vegetación y climas; sin embargo, la mayoría se encuentran a alturas menores a los 400 msnm, en selva baja caducifolia y con clima cálido-subhúmedo. En algunos sitios donde se había reportado su presencia no pudo ser encontrado durante los muestreos realizados. En la cueva El Salitre, la temperatura y humedad en sus sitios de percha permanecieron estables a lo largo del año. La primera variable osciló de 25.8 a 26.9°C y la segunda de 92.1 a 100%. Los individuos usualmente se cuelgan en las partes bajas de las paredes y en techos inclinados, utilizando también cavidades de disolución y ocasionalmente grietas. Perchan individualmente sin estar en contacto directo uno con otro, manteniendo una distancia de 5-50 cm. Se registraron 45 especies de murciélagos asociadas a N. stramineus, pero con mayor frecuencia a Pteronotus parnellii, Mormoops megalophylla, Glossophaga soricina y Desmodus rotundus. N. stramineus prefiere ocupar secciones cálidas y muy húmedas de los refugios, siendo estas condiciones ideales para conservar el calor corporal y mantener en buen estado sus alas. Su gran tendencia a asociarse con mormópidos y algunos filostómidos se explica, en parte, por requerir condiciones microclimáticas similares en sus refugios, así como por los beneficios termoregulatorios que tiene el agrupamiento en colonias. Este murciélago depende mucho de cuevas de calor para su supervivencia y ocupa de manera oportunista minas con características microclimáticas similares.
