“…Altogether, the 82 faecal pellets examined clustered into 41 separate bat genotypes, of which 7 genotypes had been detected already during earlier studies (for example Laine et al 2013;Lilley et al 2013Lilley et al , 2014Vesterinen et al 2013;Veikkolainen et al 2014). Of all the samples, 18 were identified as females and 55 as males.…”

Optimal foraging theory predicts that predators are selective when faced with abundant prey, but become less picky when prey gets sparse. Insectivorous bats in temperate regions are faced with the challenge of building up fat reserves vital for hibernation during a period of decreasing arthropod abundances. According to optimal foraging theory, prehibernating bats should adopt a less selective feeding behavior--yet empirical studies have revealed many apparently generalized species to be composed of specialist individuals. Targeting the diet of the bat Myotis daubentonii, we used a combination of molecular techniques to test for seasonal changes in prey selectivity and individual-level variation in prey preferences. DNA metabarcoding was used to characterize both the prey contents of bat droppings and the insect community available as prey. To test for dietary differences among M. daubentonii individuals, we used ten microsatellite loci to assign droppings to individual bats. The comparison between consumed and available prey revealed a preference for certain prey items regardless of availability. Nonbiting midges (Chironomidae) remained the most highly consumed prey at all times, despite a significant increase in the availability of black flies (Simuliidae) towards the end of the season. The bats sampled showed no evidence of individual specialization in dietary preferences. Overall, our approach offers little support for optimal foraging theory. Thus, it shows how novel combinations of genetic markers can be used to test general theory, targeting patterns at both the level of prey communities and individual predators.

“…Of the 13 species of bats occurring in Finland, the species sampled here represent the most common and accessible ( Myotis daubentonii , Eptesicus nilssonii , M. brandtii , M. mystacinus , and Plecotus auritus ). Based on both the Finnish Biodiversity Information Facility (http://www.laji.fi) databases and our own bat sampling, spanning for more than 10 years, these bat species constitute approximately 90%–98% of all bat occurrences in Finland, and have been the focus of most bat research in Finland so far (Jakava‐Viljanen, Lilley, Kyheröinen, & Huovilainen, ; Laine, Lilley, Norrdahl, & Primmer, ; Lilley et al, ; Lilley, Stauffer, Kanerva, & Eeva, ; Lilley, Veikkolainen, & Pulliainen, ; Veikkolainen, Vesterinen, Lilley, & Pulliainen, ).…”

Differences in diet can explain resource partitioning in apparently similar, sympatric species. Here, we analyzed 1,252 fecal droppings from five species (Eptesicus nilssonii, Myotis brandtii, M. daubentonii, M. mystacinus, and Plecotus auritus) to reveal their dietary niches using fecal DNA metabarcoding. We identified nearly 550 prey species in 13 arthropod orders. Two main orders (Diptera and Lepidoptera) formed the majority of the diet for all species, constituting roughly 80%–90% of the diet. All five species had different dietary assemblages. We also found significant differences in the size of prey species between the bat species. Our results on diet composition remain mostly unchanged when using either read counts as a proxy for quantitative diet or presence–absence data, indicating a strong biological pattern. We conclude that although bats share major components in their ecology (nocturnal life style, insectivory, and echolocation), species differ in feeding behavior, suggesting bats may have distinctive evolutionary strategies. Diet analysis helps illuminate life history traits of various species, adding to sparse ecological knowledge, which can be utilized in conservation planning.

“…Microscopic lesions, including hepatic necrosis, vacuolation, inflammation and atrophy, as well as renal necrosis and inflammation, were reported in Neoromicia nana feeding at wastewater treatment sites, with elevated tissue levels of iron, zinc, and copper; other studies of this population documented DNA damage and decreased antioxidant capacity (Naidoo et al, 2013(Naidoo et al, , 2015(Naidoo et al, , 2016Zocche et al, 2010). Organic tin compounds have been associated with decreased complement activity and a possible decrease in immune response in Myotis daubentonii (Lilley et al, 2013).…”
