Article Synopsis
- Understanding speciation is complex, especially in bats due to hybridization and interspecific variation, making it hard to unravel relationships among closely related species.
- The study focuses on three closely related endemic South American bat species: Eptesicus (Histiotus) macrotus, Eptesicus (Histiotus) montanus, and Eptesicus (Histiotus) magellanicus, which are morphologically similar but struggle to be differentiated at the molecular level.
- Findings reveal strong gene flow and recent hybridization between E. (H.) montanus and E. (H.) macrotus, while E. (H.) magellanicus is more isolated, suggesting that using both nuclear and
Bats are widespread mammals of the order Chiroptera. They are key for ecosystem functioning, participating in crucial processes. Their unique ability amongst mammals to fly long distances, their frequently large population sizes, and their longevity favor infectious agent persistence and spread.

- The Chilean myotis, the southernmost bat species, has a limited understanding of its biology despite a distribution spanning about 2800 km mostly along the eastern Andes.
- The study utilized a double digestion RAD-seq method on 66 individuals and found a significant isolation-by-distance pattern, with southern populations displaying higher genetic diversity than northern ones.
- Low connectivity between southern hibernating populations and northern ones suggests a reduced risk of disease spread, particularly in light of threats like bat white-nose syndrome.
Coffee production is a global industry valued at approximately 173 billion US dollars. One of the main challenges facing coffee production is the management of the coffee berry borer (CBB), Hypothenemus hampei, which is considered the primary arthropod pest of coffee worldwide. Current control strategies are inefficient for CBB management.

Bats are the ancestral and most prevalent hosts for cimicids. Cimicids have a worldwide distribution matching that of their hosts, but the global classification is incomplete, especially for species outside the most common Cimicidae taxa.
