The mammal fauna consists of seventy-six species, of which two vespertilionid bats are endemic to this ecoregion (Table 1).    From Wordnik.com.  [Western Himalayan broadleaf forests] Reference

There were at least two native mammals in the ecoregion, the Critically Endangered Bonin fruit bat (Pteropus pselaphon), and now Extinct vespertilionid bat Pipistrellus sturdeei.    From Wordnik.com.  [Ogasawara subtropical moist forests] Reference

The researchers discovered that the migratory behaviour over long and short distances evolved repeatedly and for the most part independently within the family of vespertilionid bats.    From Wordnik.com.  [Daily News & Analysis] Reference

"We assume that the evolution of migratory behaviour in the vespertilionid bats is an answer to sinking temperatures in their habitats, which made a temporary migration into warmer areas necessary," he said.    From Wordnik.com.  [Daily News & Analysis] Reference

According to Kamran Safi, one of the authors of the study, "According to the model, the probability for the vespertilionid bats to loose or gain their residential habitat is the same as becoming a short or long distance migrant".    From Wordnik.com.  [Daily News & Analysis] Reference
