# Fungal and bat diversities along a landscape gradient in central Mexico

## TL;DR

This study explores how bat and fungal species diversity changes across different landscapes in central Mexico.

## Contribution

The paper documents new associations between bat species and fungi along a landscape gradient in central Mexico.

## Key findings

- Higher bat and fungal diversity was observed in conserved sites compared to urban areas.
- Penicillium and Aspergillus were the most abundant fungal genera found in bat samples.
- M. californicus in conserved sites and M. velifer in urban sites showed the highest fungal diversity.

## Abstract

Species interactions between bats and fungi are poorly known. We documented the association between fungal and bat diversities along a landscape gradient. Ten, eight, and seven bat species were captured in conserved, semi-conserved, and urban sites, respectively. Eptesicus fuscus, Myotis ciliolabrum and Corynorhinus townsendii were the most abundant in conserved and semi-conserved sites. E. fuscus, Myotis velifer, and Lasiurus cinereus were abundant in urban sites. C. townsendii was the least abundant bat. A total of 15 cultivated fungi genera included the fungal diversity in bats, of which nine fungi genera were shared along the landscape gradient. Penicillium and Aspergillus were the most abundant genera, and Aureobasidium, Bispora, Stachybotrys, and Verticillium were only documented in the conserved sites. We observed a higher fungal diversity associated with bat species along this landscape gradient. The individual site-based accumulation curves of fungal diversity showed significant decreasing values along the conserved, semi-conserved, and urban sites, respectively. In conserved and urban sites, M. californicus and M. velifer showed the highest fungal diversity, respectively. E. fuscus was associated to the fungi genera Scopulariopsis, Alternaria, Penicillium and Beauveria; L. cinereus to Cladosporium and Aspergillus, and M. velifer to Alternaria sp1, Bispora and Trichoderma. Conserved sites showed both high bat and fungal diversities [species richness and abundance] compared to semi-conserved and urban sites. More studies associating bat and fungal diversities in other ecosystems are needed to corroborate this pattern.
