High genetic variation, low differentiation, and Pleistocene expansions of the migratory and endangered long-nosed tequila bat, Leptonycteris nivalis, inferred using both maternal and paternal genetic markers.

Tequila bats (genus Leptonycteris) have gained attention for their critical role in pollinating different plant species, especially Agave spp. and columnar cacti. Leptonycteris nivalis is the largest nectar-feeding bat in the Americas, and the females exhibit migratory behavior during the breeding season.

Move past promises for biodiversity.

As nations convene this week in Cali, Colombia, at the Sixteenth Conference of the Parties (COP16) to the Convention on Biological Diversity (CBD), the alarming rate at which the world is losing biodiversity will again be in the spotlight. Habitat destruction, climate change, pollution, and unsustainable use of resources continue to drive this loss. COP16 (the organization's highest authority) presents another opportunity for world leaders to do more than just assess progress and renew commitments, and instead adopt binding obligations for the entire world.

The state of the bats in North America.

The world's rich diversity of bats supports healthy ecosystems and important ecosystem services. Maintaining healthy biological systems requires prompt identification of threats to biodiversity and immediate action to protect species, which for wide-ranging bat species that span geopolitical boundaries warrants international coordination. Anthropogenic forces drive the threats to bats throughout North America and the world.

Hibernacula of bats in Mexico, the southernmost records of hibernation in North America.

Although Mexico holds the southernmost hibernating bats in North America, information on winter behavior and hibernacula microclimate use of temperate Mexican bats is limited. We studied hibernating bats at high altitudes (>1,000 m a.s.

Potential for spatial coexistence of a transboundary migratory species and wind energy development.

Global expansion in wind energy development is a notable achievement of the international community's effort to reduce carbon emissions during energy production. However, the increasing number of wind turbines have unintended consequences for migratory birds and bats. Wind turbine curtailment and other mitigation strategies can reduce fatalities, but improved spatial and temporal data are needed to identify the most effective way for wind energy development and volant migratory species to coexist.
