“…Our results indicate that prevalence variation and number of streblid species is specific for each bat species, suggesting that the bat species abundance and type of roost are not the main contributing factors. An alternative explanation for streblid richness and prevalence variability per host could be related to complexity in the cave structure complexity, which affects air flow and the amount of light per area, creating different microhabitats (McNab, 1974;Torres-Flores & López-Wilchis, 2010). However, this only can be confirmed after the microclimatic conditions per perching site inside the caves are assessed.…”

“…La importancia de las cuevas para los murciélagos es más notable en la región Neotropical, donde se ha reportado a más de 10 especies en una sola cueva formando colonias muy numerosas (Arita 1993, Trajano & Gimenez 1998, Gregorin & Mendes 1999, Torres-Flores & López-Wilchis 2010. Estas comunidades cavernícolas ofrecen buenas oportunidades de estudio y algunos autores han abordado los patrones de asociación interespecífica (Graham 1988, Arita & Vargas 1995, Rodríguez-Durán 1998; las pautas en la selección de refugios (Vargas 1998, Ávila-Flores & Medellín 2004 y la ecología poblacional y reproductiva de sus especies (Trajano 1985, Martino et al 1997.…”

Population dynamics, roost selection and reproductive patterns of some cave bats from Western of Mexico. Almost half of bat species that occur in Mexico use caves as permanent or temporal roosts. However, the ecological studies about cave bat communities are scarce. In this work we studied the population dynamics, roost selection and reproductive patterns of some bats present in El Salitre Cave, Colima, Mexico. We carried out monthly samplings between August 2003-March 2005 using a harp trap for bats capture, we took their biological data and marked some of them with plastic rings. We also explored the cave to locate bat colonies and register microclimatic conditions in each cave section. We captured a total of 16 409 bats of which 31% were Mormoops megalophylla, 24.5% Pteronotus personatus, 23% P. davyi, 8.2% P. parnellii, 5.8% Natalus mexicanus and 5.3% Glossophaga soricina. Macrotus waterhousii, G. morenoi, Desmodus rotundus, Balantiopteryx plicata, and Glyphonycteris sylvestris represented only 2.2% of the captures. Some bat species used the cave as a permanent day roost while others as a seasonal one, and their population size varied markedly along the year and between rainy and dry seasons. Most bat population peaks were linked with their reproductive periods. The Pteronotus species and N. mexicanus exhibited sexual segregation during the breeding season. The mormoopids and N. mexicanus occupied deeper parts of the cave with temperatures >25.8°C and relative humidity >99%. The phyllostomids occupied intermediate sections where the ambient was less hot and humid, with temperatures of 23.2-28.3°C and humidity of 74-89.9%. Some individuals of B. plicata and G. sylvestris were seen occasionally occupying one chamber near the entrance two, where temperature and humidity were of 23.2°C and 84.2%, respectively. The mormoopids and N. mexicanus showed a pattern of seasonal monoestry, synchronized with rainy season. Glossophaga soricina had a pattern of bimodal seasonal poliestry, with one reproductive peak to early of dry season and another to last of this season. Macrotus waterhousii did not exhibit a seasonal pattern, with parturitions occurring throughout the year. Our results indicate a seasonal replacement between several species as well as seasonal movements to other caves. The data indicate that the carrying capacity of the cave is mainly determined by the availability of roosting sites. The selection of roosting sites is linked to the close relationship between microclimatic conditions and the species physiological characteristics. The reproduction of mormoopids and N. mexicanus was mostly influenced by rainfall which determinates food availability. Rev. Biol. Trop. 60 (3): 1369-1389. Epub 2012 September 01.

“…This may be a consequence of habitat fragmentation, which should be interpreted as a warning signal, given that the loss of genetic variation and flow can reduce the ability of individuals to adapt to a changing environment, resulting in endogamic depression [121], lower reproduction [122,123], and a higher probability of extinction [124,125]. The information obtained for Natalus mexicanus in this study is also alarming because the current status of most of its populations is unknown [40], and during the development of our field work, we have been able to verify that some populations have either declined or completely disappeared due to human disturbances [126].…”

Genetic Consequences of Forest Fragmentation in a Widespread Forest Bat (Natalus mexicanus, Chiroptera: Natalidae)

Recent historical and anthropogenic changes in the landscape causing habitat fragmentation can disrupt the connectivity of wild populations and pose a threat to the genetic diversity of multiple species. This study investigated the effect of habitat fragmentation on the structure and genetic diversity of the Mexican greater funnel-eared bat (Natalus mexicanus) throughout its distribution range in Mexico, whose natural habitat has decreased dramatically in recent years. Genetic structure and diversity were measured using the HVII hypervariable domain of the mitochondrial control region and ten nuclear microsatellite loci, to analyze historical and contemporary information, respectively. The mitochondrial and nuclear results pointed to a differential genetic structuring, derived mainly from philopatry in females. Our results also showed that genetic diversity was historically high and currently moderate; additionally, the contemporary gene flow between the groups observed was null. These findings confirm that the effects of habitat fragmentation have started to be expressed in populations and that forest loss is already building barriers to contemporary gene flow. The concern is that gene flow is a process essential to ensure that the genetic diversity of N. mexicanus populations (and probably of many other forest species) distributed in Mexico is preserved or increased in the long term by maintaining forest connectivity between locations.
