A glimpse into the foraging and movement behavior of Nyctalus aviator: a complementary study by acoustic recording and GPS tracking
<p>Species of open-space bats that are relatively large, such as bats from the genus <em>Nyctalus</em>, are considered as high-risk species for collisions with wind turbines. However, important information on their behavior and movement ecology, such as the locations and altitudes at which they forage, is still fragmentary, while crucial for their conservation in light of the increasing threat posed by progressing wind turbine construction. We adopted two different methods of microphone array recordings and GPS-tracking capturing data from different spatio-temporal scales in order to gain a complementary understanding of the echolocation and movement ecology of <em>Nyctalus aviator</em>, the largest open-space bat in Japan. Based on microphone-array recordings, we found that echolocation calls during natural foraging are adapted for fast-flight in open space optimal for aerial-hawing. In addition, we attached a GPS tag that can simultaneously monitor feeding buzz occurrence and confirmed that foraging occurred at 300 m altitude and that the flight altitude in mountainous areas is consistent with the turbine conflict zone. Thus, our acoustic GPS survey clearly identified<em> N. aviator</em> as a high-risk species in Japan.</p>

Bird species in the diet of the birdlike noctule bat, Nyctalus aviator, in Japan.
<p>We investigate the birds in the diet of the birdlike noctule (<i>Nyctalus aviator</i>) through DNA amplification from feather remains found in fecal pellets. Our goal was to confirm that <i>N. aviator</i> preys on nocturnally migratory species, as does its European relative <i>N. lasiopterus</i>, and to gain insights into this hunting strategy (e.g. on the wing vs. from cavity-nest). The diversity and the characteristics of the birds found in the feces remains indicate that in Japan <i>N. aviator</i> employs a similar hunting strategy on songbirds as <i>N. lasiopterus</i> in Iberia. Both noctules are primarily generalist insectivores that prey on 5-25 g body mass songbirds seasonally during their migration and probably hunt them at high altitude. Accordingly, predation on birds seems to be a strategy that appears in distant points across the Palearctic and is not the result of local specialization. We hypothesize that the bird hunting behavior appeared during evolution as a trophic jump from a pre-existing hunting behavior on the many insects that carry out seasonal nocturnal migrations in temperate zones at high-altitude.</p>
Data from: New insights on postglacial colonisation in Western Europe: the phylogeography of the Leisler's bat (Nyctalus leisleri)
Despite recent advances in the understanding of the interplay between a dynamic physical environment and phylogeography in Europe, the origins of contemporary Irish biota remain uncertain. Current thinking is that Ireland was colonized post-glacially from southern European refugia, following the end of the last glacial maximum (LGM), some 20 000 years BP. The Leisler's bat (Nyctalus leisleri), one of the few native Irish mammal species, is widely distributed throughout Europe but, with the exception of Ireland, is generally rare and considered vulnerable. We investigate the origins and phylogeographic relationships of Irish populations in relation to those across Europe, including the closely related species N. azoreum. We use a combination of approaches, including mitochondrial and nuclear DNA markers, in addition to approximate Bayesian computation and palaeo-climatic species distribution modelling. Molecular analyses revealed two distinct and diverse European mitochondrial DNA lineages, which probably diverged in separate glacial refugia. A western lineage, restricted to Ireland, Britain and the Azores, comprises Irish and British N. leisleri and N. azoreum specimens; an eastern lineage is distributed throughout mainland Europe. Palaeo-climatic projections indicate suitable habitats during the LGM, including known glacial refugia, in addition to potential novel cryptic refugia along the western fringe of Europe. These results may be applicable to populations of many species.
