“…This study includes the largest number of samples and localities analyzed so far for L. yebabuenae (Wilkinson & Fleming, 1996;Morales-Garza et al, 2007;Arteaga et al, 2018;Menchaca et al, 2020). As amplification of the D-loop showed difficulties -apparently because of poorer preservation state of the oldest samples or a bias originated by the oligonucleotide used for its amplification such as mutations in primer binding site -we had sample size differences between molecular markers; thus, some inferences may be interpreted with caution (Jennions & Møller, 2002;Nazareno & Jump, 2012).…”

“…Previous genetic studies based on mitochondrial, microsatellites and Random Amplified Polymorphic DNA markers (RAPDs) have concluded that there are different genetic groups along the species distribution (Wilkinson & Fleming, 1996;Morales-Garza et al, 2007). Wilkinson & Fleming (1996) proposed a coastal and an inland group, in accordance with migration routes, supported by Rojas-Martínez et al (1999) and Menchaca et al (2020). However, these studies did not analyze resident groups from permanent roosting caves.…”

Leptonycteris yerbabuenae, the lesser long-nosed bat is an abundant migratory nectar-feeding bat found in most of Mexico, and in some areas of northern Central America and small sections of southwestern USA. We analyzed the distribution of the maternal and paternal lineages of this species with phylogeographic methods based on two mitochondrial markers, Cyt-b and D-loop, and a marker located in the Y chromosome, DBY. We obtained tissue samples from 220 individuals from 23 localities. Levels of genetic diversity (haplotype diversity, Hd) were high (Cyt-b = 0.757; D-loop = 0.8082; DBY = 0.9137). No clear patterns of population genetic structure were found for mitochondrial markers, while male genetic differentiation suggested the presence of two lineages: one from Mexican Pacific coast states and another from central-southern Mexico; in accordance to strong male philopatry and higher female migration. We used genealogical reconstructions based on Bayesian tools to calculate divergence times, and to test coalescent models to explain changes in L. yerbabuenae historical demography. Our results show that recent demographic changes were consistent with global climatic changes (∼130,000 kyr ago for Cyt-b and ∼160,000 kyr for D-loop) and divergence times dated from molecular genealogies exhibited older divergence times, Cyt-b (4.03 mya), D-loop (10.26 mya) and DBY (12.23 mya). Accordingly, the female lineage underwent demographic expansion associated to Pleistocene climate change, whereas the male lineage remained constant.

“…Leptonycteris yerbabuenae, also called the tequila bat, is a key species for the tequila and mezcal industry. As such, it has been the focus of intense research over the last 20 years (Menchaca et al 2020). These last authors claim that the close relationship between this bat and economically important plants has raised awareness of its importance as both a keystone mutualist, exchanging food for pollination, and a mobile link between habitats.…”

“…A high percentage of the distribution range of the lesser long-nosed bat coincides with the distribution of the mezcal plant (Agave angustifolia) in México (Arita 1991). There is a close relationship between these two species, so the lesser longnosed bat is a keystone mutualist and also it is a key mobile link between habitats (Menchaca et al 2020). This relationship has very important economic implications (Menchaca et al 2020).…”

This relationship has very important economic implications (Menchaca et al 2020). However, it has been suggested that due to the biological features associated with the specialized diet, nectar-feeding bats might be more vulnerable to extinction than other bats (Arita and Santos del Prado 1999).…”

The lesser long-nosed bat (Leptonycteris yerbabuenae Martínez & Villa-R, 1940) is a specialized nectar feeding species found from southern USA to Nicaragua in Central America, mostly in dry forest. We sampled bats using mist nets and Anabat detectors, and also looked for them at refuges and other sites in Honduras from 2011 to 2016. The lesser long-nosed bat is known in Honduras from only two localities in the southern dry forests below 100 m elevation, and there are no recent records of this species in the country. Our objective is to report new records on distribution and habitat of the lesser long-nosed bat in Honduras. We found eight lesser long-nosed bats at Cerro de Hula, Francisco Morazán department in 2012, and 10 at La Anonilla, Choluteca department, southern Honduras in 2015. Based on these 18 individuals of the lesser long-nosed bat, we report two new localities in Honduras, an altitude record, and the use of another habitat other than the dry forest. The highest point registered was at 1710 m a.s.l. in pastureland with forest remnants in an area heavily impacted by human activities. The new localities are found in the Subtropical Moist Forest. Populations of long-nosed bats in Honduras are probably resident and may include altitudinal movements. Although this species has been described widely in North America, its behavior in Honduras is practically unknown. It is a key species for the tequila and mezcal industry, but its range extends beyond the tequila production area, where it maintains a key role as a pollinator and link between habitats. As a result, research and conservation efforts should be an international goal.

The biogeographic history of the Chihuahuan Desert is complex, driven by numerous physiographic events and climatic changes. This dynamic history would have influenced the flora and fauna of the region including the desert pocket gopher, Geomys arenarius, a subterranean rodent endemic to the northern Chihuahuan Desert. G. arenarius is restricted to sandy soils and are considered to have a disjunct distribution. Two subspecies are recognized: G. a. arenarius and G. a. brevirostris. We used multilocus nuclear (amplified fragment length polymorphisms) and mitochondrial DNA (ND2) sequence data to uncover patterns of genetic diversity within and among populations of G. arenarius. We evaluated correspondence of genetic patterns to traditionally accepted subspecies boundaries, mapped the distribution of potentially suitable soils to identify barriers or corridors to dispersal and to guide future survey efforts, provided evidence that could be used to recognize distinct population segments, and quantified genetic diversity within populations. Both datasets were largely concordant and demonstrated hierarchical patterns of genetic divergence. The greatest divergence was consistent with the two recognized subspecies. Mapping of potentially habitable soils revealed likely barriers to dispersal contributing to the allopatric pattern of geographic distribution and areas, which may be occupied by G. arenarius but not yet documented. Because G. arenarius is restricted to soils with high sand content, and these habitable soils are disjunct within the region occupied by this species, historical factors that impacted soil deposition and deflation likely contributed to the observed patterns of genetic divergence. Genetic diversity was higher within populations of the southern subspecies (G. a. arenarius) compared to G. a. brevirostris. This may be due to a greater availability of continuous suitable soils within the range of G. a. arenarius or higher density due to greater food availability (currently or historically)—both of which could allow for a higher effective population size.
