Guidelines for use of wild mammal species are updated from the American Society of Mammalogists (ASM) 2007 publication. These revised guidelines cover current professional techniques and regulations involving mammals used in research and teaching. They incorporate additional resources, summaries of procedures, and reporting requirements not contained in earlier publications. Included are details on marking, housing, trapping, and collecting mammals. It is recommended that institutional animal care and use committees (IACUCs), regulatory agencies, and investigators use these guidelines as a resource for protocols involving wild mammals. These guidelines were prepared and approved by the ASM, working with experienced professional veterinarians and IACUCs, whose collective expertise provides a broad and comprehensive understanding of the biology of nondomesticated mammals in their natural environments. The most current version of these guidelines and any subsequent modifications are available at the ASM Animal Care and Use Committee page of the ASM Web site (http://mammalsociety.org/committees/index.asp).

Natural disturbances can have large effects on ecosystem structure and function depending on their scale, and frequency. On 18 September 1989 Hurricane Hugo struck Puerto Rico, with the eye of the hurrica within 10 km of the Luquillo Experimental Forest. This provided a rare opportunity to evaluate the eff infrequent but large scale and high intensity disturbance on tropical bat species. Data on demographic p of three common phyllostomid bats (Artibeusjamaicensis, Stenoderma rufum, and Monophyllus redmani) wer for three years prior and three years after the hurricane. Population levels as estimated by captures per ne all three species were affected by Hurricane Hugo. Populations of A. jamaicensis and M. redmani retu predisturbance levels within two years. In contrast, population levels of S. rufum declined to about 30 prehurricane levels and have not recovered after three years. Moreover, telemetry data indicate that fora home range size expanded to encompass an area approximately five times larger than its prehurricane size of foraging, in terms of time and energy, may be considerably elevated over prehurricane scenarios. In fact, a s change in the age structure of the population (juvenile individuals have been absent from the popula Hurricane Hugo) as well as significant decline in the percent of reproductively active females indicate a fa reproduce in the posthurricane environment. RESUMENEl impacto de disturbios naturales en la estructura y funcinamiento de ecosistemas depende de la escala, intensida y frequencia de estos. El 18 de septiembre de 1989 el ojo del huracan Hugo pas6 a menos de diez kilometros d Bosque Experimental de Luquillo. Este evento provey6 la rara oportunidad de estudiar los efectos de un distur de alta intensidad y gran escala, pero baja frequencia, en las especies de murcielagos del bosque. Datos demografico de tres especies comunes de murcielagos filost6midos (Artibeus jamaicensis, Stenoderma rufum y Monophyllus redm fueron colectados por tres a-nos previos y tres anos seguidos al huracan. Los niveles poblacionales de estas tres espec estimados en capturas por red-hora, fueron afectados por el paso del huracan. Las poblaciones de A. jamaicens M. redmani retornaron a niveles prehuracan en dos anios. Los niveles poblacionales de S. rufum depreciaron a cerc del 30 por ciento de los niveles prehuracan, y tres anios despues del disturbio aun no se han recobrado. MWs a datos de telemetria indican que el tamaiio de las areas de forageo y ambito nativo de S. rufum fueron expandi cerca de cinco veces lo que eran antes del huracan. El costo de forageo, en terminos de tiempo y energia, puede qu sea considerablemente mas alto en escenarios posthuracan. De hecho, un cambio significativo en la estructura de e de la poblaci6n ha ocurrido (no hemos encontrado juveniles desde el paso del hurac6n). Esta reestructuraci6n estado acompaiiada por una reducci6n significativa en el porciento de la actividad reproductiva de las hembras que indica que esta especie no ha podido reproducirse exitosamente despues d...

Between April and October 1997, 689 bats representing seven species were captured at Pennsylvania's Canoe Creek State Park. Each bat was sampled for ectoparasitic arthropods, and four species were collected from 13.2% of the host individuals. Ectoparasites include the bat flea Myodopsylla insignis (Rothschild), the wing mite Spinturnix americanus (Banks), the bed bug Cimex adjunctus Barber, and the soft tick Ornithodoros kelleyi Cooley & Kohls. Prevalence, relative density, and mean intensity were calculated for ectoparasites of Myotis lucifugus (Le Conte), which harbored all four ectoparasite species and was the most commonly captured host. Patterns of ectoparasite associations were examined with respect to host sex and habitat (roost characteristics). Female M. lucifugus hosted higher densities of ectoparasites than did males. Moreover, relative densities of ectoparasites from M. lucifugus were dependent on the proximate roost; hosts captured near Bat Church were more heavily parasitized than those captured near Hartman Mine. Two other bat species were infested with at least one ectoparasite, but sample sizes were too small to analyze statistically. These bat species included Myotis septentrionalis (Trouessart), harboring M. insignis, S. americanus, and O. kelleyi, and Eptesicus fuscus (Beauvois), which harbored M. insignis and O. kelleyi.
