“…When we excluded data from Orta‐Pineda et al ( 2020 ; see Materials and Methods), we found a weaker overall effect of forest fragmentation on all parasite outcomes. Roost duration was still an important and significant predictor for prevalence.…”

“…One study in our analysis provided a unique description of the habitats that were sampled; all sites experienced some degree of fragmentation, but some could still be considered continuous forest depending on when the land was last cleared (Orta‐Pineda et al, 2020 ). After excluding this study from our meta‐analysis, we observed similar results for the moderator variables (notably, the wing aspect ratio was still an important predictor for all outcomes), yet the overall effects of forest type on parasite outcomes were weaker.…”

“…We retained this study in our analyses because (1) fallow land could be considered continuous forest depending on the time since clearance, and (2) almost all studies retained in our analyses describe some degree of human disturbance, even in the continuous forests (Appendix S2 , Table A1). For the gap analysis, the inclusion of Orta‐Pineda et al ( 2020 ) highlights the importance of quantitative measures of habitat characteristics in assigning fragmentation categories. For the meta‐analysis, we included this study in the primary analyses below and provide results with it excluded in the Supporting Information (Appendix S2 ); however, the inclusion or inclusion of this study did not result in dramatically different trends (see Sensitivity to the influential study in Results ).…”

“…When we conducted a Cook's distance test clustered by study (using the metafor package), Orta‐Pineda et al ( 2020 ) was identified as influential; however, this study (and one other influential study; Frank et al ( 2016 )), each contributed more than five times more data records than the third largest study in our dataset. We thus conducted a secondary series of analyses identical to our primary analyses with Orta‐Pineda et al ( 2020 ) excluded. Complete results for this second analysis are provided in Appendix S2 (Table A3–A7).…”

“…Most studies that met our inclusion criteria provided clearly demarcated habitats as either fragmented or continuous forests, or were sampled along gradients where the extremes could be classified as either fragmented or continuous. However, the habitats in one study did not align as closely with these categories (Orta-Pineda et al, 2020). Here, bats were sampled along a disturbance gradient, ranging from fully disturbed pasture to fallow land that included shrubs, trees, and grasses.…”

Tropical regions are experiencing rapid rates of forest fragmentation, which can have several effects on wildlife, including altered parasite dynamics. Bats are a useful host group to consider the effects of fragmentation, because they are abundant in the tropics, serve important ecological roles, and harbor many parasites. Nevertheless, research on the effects of fragmentation on bat ectoparasites is still limited. To help guide ongoing and future research efforts, this study had two objectives: (1) conduct a gap analysis to characterize the state of currently available research on fragmentation effects on bat ectoparasites and (2) conduct a preliminary meta‐analysis to identify current trends. We systematically highlighted several research gaps: Studies comparing the effects of fragmented versus continuous forests on ectoparasites are limited and have primarily been conducted in the Neotropics, with a focus on bats in the superfamily Noctilionidea (especially frugivorous phyllostomids). Our preliminary meta‐analysis suggested that ectoparasite prevalence (but not the mean or variance in intensity) was higher in fragments than in continuous forests. Moreover, prevalence increased with increasing roost duration, and mean intensity was higher for bats with higher wing aspect ratios. Intensity variance was affected by an interaction between forest type and wing aspect ratio, such that variance increased for bats with high‐wing aspect ratios in continuous forests but decreased in fragments. These results suggest that fragmentation can shape aspects of bat ectoparasitism and could have implications for the ecology, health, and conservation of bats in fragmented landscapes. However, existing research gaps could bias our current understanding of habitat change and bat health, and future research should thus investigate these effects in the Paleotropics and with other bat families.

The ectoparasites of the bats (Chiroptera) often act as carriers of infectious agents dangerous to animals and humans. This determines the relevance of studying ectoparasite communities. In this regard, the composition of communities and interspecific relations of ectoparasites of migratory bats are of particular interest, since they can be a source of arthropods with vector potential that are atypical in a studied area. This research was aimed to study the species composition, community structure and parasite-host specificity of ectoparasites in syntopic populations of bats of the genus Nyctalus. The study has been carried out in the Zhiguli State Biosphere Reserve and Samarskaya Luka National Park (Russia). A total of 78 individuals of Nyctalus were examined, namely Nyctalus noctula (47 individuals), N. leisleri (21 individuals) and N. lasiopterus (ten individuals). They were captured by ornithological nets in the summer period in 2017–2019. The collected ectoparasites were fixed in alcohol, and permanent preparations were made using Fora-Berlese liquid. In total, we found 19 ectoparasite species, namely one Hemiptera species (Cimex lectularius), four Ischnopsyllidae species, and 14 species of Spinturnicidae and Macronyssidae families. Of these, eight ectoparasite species have been found for the first time in Russia on Nyctalus species. Nine ectoparasites species were found on Nyctalus leisleri, 15 species on N. noctula, and 11 species on N. lasiopterus. The most massive and widespread parasite on Nyctalus is Macronyssus flavus. In addition, we demonstrated a high infestation of Nyctalus noctula by Spinturnix acuminatus and Steatonyssus noctulus, of Nyctalus lasiopterus by Spinturnix acuminatus and of Nyctalus leisleri by Steatonyssus spinosus. Among casual parasites of Nyctalus, there are Spinturnix helvetiae, S. myoti, S. plecotinus, Ischnopsyllus octactenus, I. variabilis, Macronyssus ellipticus, and Steatonyssus periblepharus. The correspondence analysis of certain ectoparasite communities, differing in qualitative and quantitative composition, with the host species demonstrated the general structure of parasite-host relationships. Nyctalus noctula has the highest diversity of ectoparasite communities and the model of the log-normal distribution of species abundance confirmed this. In terms of species composition, the parasite communities of Nyctalus noctula and N. lasiopterus were the most similar, while the parasite communities of Nyctalus noctula and N. leisleri were the least similar. The key components involved in the differentiation of ectoparasitic communities were the following species: Spinturnix acuminatus, S. kolenatii, Steatonyssus spinosus, and Macronyssus flavus, which have different infestation values in their hosts. Co-occurrence analysis revealed a strong positive relationship for 28 ectoparasite species pairs and a strong negative relationship for 26 species, which may be explained by weakened competitive relations between the ectoparasites. The observed assortativity of parasite species among themselves has been discussed.
