The frequency and intensity of hurricanes have increased with climate change, and their effects on most taxa are not known. We analyzed a species diversity of bats in three locations with different regimes of anthropic disturbance. We assessed the effect of the season and post-hurricane time on the abundance of trophic guilds in coastal Jalisco, Mé...

The frequency of high-intensity hurricanes has increased in past decades, making it necessary to understand their impacts on biological diversity. The disturbance by cyclones adds to the anthropic disturbance and generates important effects on ecosystems. Bats are ideal bioindicators that show several responses to impacts of hurricanes in insular s...

In our recent epidemiological survey conducted in Mexico for hantavirus infection, we identified three distinct viruses circulating in Mexican wild rodents, namely Montano virus (MTNV), Huitzilac virus (HUIV), and Carrizal virus (CARV). To gain a detailed understanding of hantavirus epidemiology and its associated hosts, 410 rodents were captured a...

The hantavirus nucleocapsid (N) protein is an important immunogen that stimulates a strong and cross-reactive immune response in humans and rodents. A large proportion of the response to N protein has been found to target its N-terminus. However, the exact nature of this bias towards the N-terminus is not yet fully understood. We characterized six...

Species co-occurrence is an important ecological research area. Mark-and-recapture studies of mammals allow identification of coexisting species, a necessary step in determining mechanisms enabling habitat sharing. Using data from five 1-ha grids in January 2004 in tropical dry deciduous forest of coastal Colima. Mexico, we detected significantly m...

Leucism is a partial hypopigmentary congenital disorder previously recorded in Mexico in seven bat specimens of six species. In August 2009, in the state of Hidalgo, we caught one Sturnira ludovici and one Artibeus lituratus (both females) exhibiting leucism. In addition, one leucistic Macrotus waterhousii was caught in April 2010, in Guerrero. Leu...
