“…The eastern bent-wing bat M. fuliginosus (Miniopteridae) used to be considered as a subspecies of the broadly distributed common bent-wing bat M. schreibersii [ 42 ], and is one of the most abundant resident bats in Kenting [ 43 ]. The reported ectoparasites of M. fuliginosus in Taiwan include bat flies of the Nycteribiidae ( Nycteribia allotopa, N. parvula, N. formosana , Penicillidia jenynsii ) and Streblidae ( Ascodipteron speiserianum ) families, and wing mites ( Spinturnix psi and S. verutus , Spinturnicidae; [ 44 , 45 ]).…”

Background Ectoparasites inhabit the body surface or outgrowths of hosts and are usually detrimental to host health and wellbeing. Hosts, however, vary in quality and may lead ectoparasites to aggregate on preferred hosts, resulting in a heterogeneous distribution of parasite load among hosts. Results We set out to examine the effects of host individual state and body condition on the parasite load of multiple nycteribiid and streblid bat flies and Spinturnix wing mites on eastern bent-wing bats Miniopterus fuliginosus in a tropical forest in southern Taiwan. We detected a high parasite prevalence of 98.9% among the sampled bats, with nearly 75% of the bats harboring three or more species of parasites. The parasite abundance was higher in the wet season from mid spring to early fall, coinciding with the breeding period of female bats, than in the dry winter season. In both seasonal periods, the overall parasite abundance of adult females was higher than that of adult males. Among the bats, reproductive females, particularly lactating females, exhibited a higher body condition and were generally most infested. The Penicillidia jenynsii and Nycteribia parvula bat flies showed a consistent female-biased infection pattern. The N. allotopa and Ascodipteron speiserianum flies, however, showed a tendency towards bats of a moderate to higher body condition, particularly reproductive females and adult males. Conclusions We found an overall positive correlation between parasite abundance and reproductive state and body condition of the host and female-biased parasitism for M. fuliginosus bats. However, the effects of body condition and female-biased infestation appear to be parasite species specific, and suggest that the mobility, life history, and potential inter-species interactions of the parasites may all play important roles.

“…A χ 2 test was used to determine if the frequency distribution was random among abundance levels. For each site, a relative importance value was estimated by incorporating the FO and relative abundance (RA) of bats (Lee et al, 2007). We assessed the correlation (Pearson's R) between FO and RA of bats, FO with the mean bat linear density (per km of transect) for both habitat type and among census nights, and the mean linear density with tree heterogeneity and density of major fruit plants.…”

The nocturnal distribution and resource use by Ryukyu flying foxes was studied along 28 transects, covering five types of habitats, on Iriomote Island, Japan, from early June to late September, 2005. Bats were mostly encountered solitarily (66.8%) or in pairs (16.8%), with a mean linear density of 2.5 ± 0.6 bats/km of transect/night. Across the island, however, bat densities were distributed non-randomly among transect-nights, not correlated with transect length, and showed a slightly clumped distribution (variance/mean = 3.3). Outskirt trails contributed higher values to the relative importance of bat abundance, but the highest mean abundances occurred mostly at village sites on the west coast, which on average devoted only a quarter of their land area to agriculture/husbandry compared to those on the east coast. This supports our prediction that higher bat abundances are found in areas with less anthropogenic interference and more forest. Among habitats, the mean total abundance and density were lower in cultivated areas than in villages and inland forests. Bat perches in cultivated areas were also lower, and were in correspondence with lower shrub and canopy heights, and less canopy coverage. Flying fox abundance was correlated moderately with the heterogeneity of the tree composition, and strongly with the density of major fruiting trees. Thirty-nine species of plants and some animal items were used by Ryukyu flying foxes, including at least 31 species of fruits, 13 species of flowers, and leaves of seven species, with 14 species new to the record. Ficus septica and F. variegata were the most frequently encountered and dominant items in both fecal and rejecta/dropped samples, followed mostly by other figs and mulberries in the former, but by larger-seed non- Moraceae plants in dropped samples. Our results suggest that for conservation of flying foxes undisturbed forests providing an adequate resource basis are of major importance.

“…Common victims include species of vespertilionid subfamilies Murininae, Kerivoulinae, Myotinae, genera Hipposideros, and Rhinolophus. Most of them are common and abundant during trapping sessions in mountain areas [51,67], foraging at understory and ground levels [68], and are seldom recorded from the lowland [30]. The decrease of open space aerial hawkers in the roadkills at higher elevation is likely due to the restriction of the elevational upper limit of species distribution in this case.…”

“…The decrease of open space aerial hawkers in the roadkills at higher elevation is likely due to the restriction of the elevational upper limit of species distribution in this case. For example, P. abramus, the most common victim species in this study, is the most abundant bat in highly disturbed landscapes in the lowland and hills [65,69] but is generally less common in the mountain areas (e.g., [67]), despite its distribution up to 1000 m [70]. Other open space bats, e.g., E. pachymous and Nyctalus plancyi, are also reported as common during acoustic surveys in mountain areas with elevations over 2000 m [51].…”

Landscape and Species Traits Co-Drive Roadkills of Bats in a Subtropical Island

The expansion of roads has threatened wildlife populations by driving casualties due to vehicle collisions. However, the ecological drivers of wildlife roadkills are not yet fully explored. We investigated the strength of landscape features and ecomorphological traits in determining spatial patterns of bat roadkills in Taiwan. In total, 661 roadkills that belonged to 20 bat species were acquired by citizen scientists between 2011 and 2019. The number and species richness of victim bats declined with increasing elevations with varying species compositions. Elevation and artificial light had significantly negative effects on the occurrence of roadkill, whereas protected area and its interaction with elevation had positive effects. Ordination analyses showed that roadkills were driven by different ecomorphological traits and landscape features. At low elevations, road casualties were associated with an aerial hawking hunting strategy. At higher elevations, roadkills were associated with higher elevational distribution. Roadkills of non-cave bats were associated with brighter environments, suggesting that bats might be exposed to higher risk when hunting insects near artificial light. Our findings suggest that management agencies shall consider both species traits and landscape features when planning impact assessments and mitigation practices of roadkills for bats and probably other wildlife, particularly when long environmental gradients are covered.
