Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage t...

Southeast Asia includes several global biodiversity hotspots and bats account for nearly one-third of mammal species currently known in the region. While acoustic methods have become widespread in bat research, basic information is often lacking on the echolocation calls produced by Asian bat species. Since such information can aid a wide variety o...

Bats are typically nocturnal. However, daylight activity (ie between one hour after sunrise and one hour before sunset) is known for a small subset of species, often associated with small oceanic islands with no diurnal avian predators. Here, we describe numerous observations of diurnal activity of Horsfield’s bat (Myotis horsfieldii), in Gunung Mu...

Many wild-animal species are harvested and sold as ornaments—a lucrative trade that contributes to the global extinction crisis and increasingly happens online. Unfortunately, research and policies addressing this threat mainly focus on charismatic and easily identified taxa, leaving the online trade in bats under-researched and bats poorly protect...

Wind energy production is growing rapidly worldwide in an effort to reduce greenhouse gas emissions. However, wind energy production is not environmentally neutral. Negative impacts on volant animals, such as bats, include fatalities at turbines and habitat loss due to land-use change and displacement. Siting turbines away from ecologically sensiti...

Known nocturnal behaviors of bees in the superfamily Apoidea, including the genus Bombus , were almost exclusively of females. Here we report observations of active free-ranging male Bombus at night in the plant nursery of the Fushan Research Center, Taiwan, in April 2022. Nectar feeding by males at inflorescences was confirmed by tongue-licking in...

Climate and land-cover changes are among major threats to biodiversity. However, the interactive effects of the two threats are often overlooked in conservation planning. Using 81 bat species occurring in Vietnam as a case, we investigated the individual and interactive effects of climate and land-cover changes, highlighting the importance of this...

It is known that the development of roadway systems can benefit bats, particularly cave- and crevice-roosting species, by providing novel roosting resources, e.g., abandoned tunnels and underpasses. However, the usage of operational road tunnels by bats, and its pros and cons are often overlooked. In the present study, we investigated bat diversity...

Bat communities in Old World tropical rainforests serve various ecological roles to sustain their habitats, yet may be vulnerable to the loss of their natural habitats. Moreover, the exact biological and ecological roles of the majority of the bats in Penang Island are still understudied. Therefore, we conducted surveys at four selected primary for...

Bats comprise a quarter of all mammal species, provide key ecosystem services and serve as effective bioindicators. Automated methods for classifying echolocation calls of free-flying bats are useful for monitoring but are not widely used in the tropics. This is particularly problematic in Southeast Asia, which supports more than 388 bat species. H...

We re examined the long term data in the Forestry Bureau’s camera trap database to investigate the morphological diversification of wild boars and pigs. Our primary goal is to elucidate the potential hybridization risk in wild populations of this endemic wild boar in Taiwan.

Recordings of bat echolocation and social calls are used for many research purposes from ecological studies to taxonomy. Effective use of these relies on identification of species from the recordings, but comparative recordings or detailed call descriptions to support identification are often lacking for areas with high biodiversity. The ChiroVox w...

Emerging technologies based on the detection of electro-magnetic energy offer promising opportunities for sampling biodiversity. We exploit their potential by showing here how they can be used in bat point counts—a novel method to sample flying bats—to overcome shortcomings of traditional sampling methods, and to maximize sampling coverage and taxo...

Emerging technologies based on the detection of electro-magnetic energy offer promising opportunities for sampling biodiversity. We exploit their potential bye showing here how they can be used in bat point counts - a novel method to sample flying bats - to overcome shortcomings of traditional sampling methods, and to maximise sampling coverage and...

The Cat Ba Biosphere Reserve is internationally renowned for its spectacular karst landscape. It covers a large area with hundreds of limestone islands and various ecosystems including caves, tropical forests, and mangroves. However, previous surveys were only conducted in terrestrial ecosystems on Cat Ba Island. Therefore, bats inhabiting mangrove...

The development of increasingly affordable ultrasonic detectors and automatic classifiers has increasingly boosted the use of acoustic recording of echolocation calls to survey bats all over the world. Echolocation call keys are crucial to reliably classify acoustic recordings, but those are not available for many regions, such as China. In the pre...

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 roadkil...

Bat communities can usually only be comprehensively monitored by combining ultrasound recording and trapping techniques. Here, we propose bat point counts, a novel, single method to sample all flying bats. We designed a sampling rig that combines a thermal scope to detect flying bats and their flight patterns, an ultrasound recorder to identify ech...

Background We investigated the diversity and behaviour of insects that visit flowers of four native Melastoma (Family Melastomataceae) species of Taiwan and a horticultural hybrid Melastoma species at the Fushan Botanical Garden, Taiwan biweekly from May to August 2020. Visits of flower-visiting insects were classified into seven behavioural catego...

Bats of Taiwan, comprising 38 species in total, are biogeographically unique (11 endemic species and 16 endemic subspecies), taxonomically diverse (six families), and play crucial ecosystem roles as seed dispersers or insect suppressors. Many of these bat species were, nevertheless, scientifically described from or newly recorded in Taiwan during t...

No PDF available ABSTRACT Climate change is one of the major threats to biodiversity. Besides increasing air temperatures, the magnitude and frequency of extreme weather events have been increasing, and are predicted to increase further in the future. To understand impacts of extreme weather on biodiversity, long-term and frequent data collections...

Species differ in vulnerability to anthropogenic land use changes. Knowledge of the mechanisms driving differential sensitivity can inform conservation strategies but is generally lacking for species‐rich taxa in the tropics. The diverse bat fauna of Southeast Asia is threatened by rapid loss of forest and expanding agricultural activities, but the...

dely distributed in the Asian tropics and subtropics, but rarely recorded across its distribution range. Here, we present the first record of C. frithii to Penang, Malaysia. An adult female was captured in Tropical Spice Garden in March 2015 by a harp trap. The record confirms the presence of the species nearly two decades after the last report fro...

Characterizing the spatial distribution of species can help understand biogeographical history and the drivers of diversity, and help guide conservation planning to optimize conservation strategies and reduce biodiversity loss. Vietnam sustains a diverse and abundance bat fauna. However, the knowledge on species richness patterns of bats and their...

Evaluation of soundscape variability is essential for acoustic-based biodiversity monitoring. To study biodiversity change, many researchers tried to quantify the complexity of biological sound. However, the analysis of biological sound remains difficult because the soundscape is made up of multiple sound sources. To facilitate the acoustic analysi...

The Southeast Asian species of Hypsugo are rare bats, except for H. cadornae and H. pulveratus, which are distributed throughout the Indomalayan region. Hypsugo macrotis is restricted to Peninsular Malaysia, Sumatra, Java and adjacent islands, and is known only from a handful of specimens. Here we report a new locality record of the species from Se...

Rhinolophus affinis sensu lato is a widespread bat species in South and Southeast Asia which shows considerable geographical variation in its morphology, echolocation call frequencies and genetics. The taxonomic status of the taxon in the Sundaic subregion remains uncertain however as the limited studies to date have been largely based on morpholog...

Kerivoula krauensis was formally described in 2007 and until recently was only known from tropical forest in central peninsular Malaysia. We report four new records, which, together with recent published collections, extend the known range for this species to peatswamps, lowland and montane forests in Borneo and Sumatra (Brunei and Indonesia), and...

Recent conservation efforts suggest large artificial roosts, such as “bat houses”, may not only serve as alternative sources of guano fertilizer but also provide opportunities to re-establish bat populations and associated ecological services in disturbed landscapes. To achieve this goal, it is essential to evaluate the economic benefits of harvest...

With the 125 species recorded, Vietnam represents one of the countries with highest bat richness among the world. Tragically, bat fauna in Vietnam is currently threatened by various anthropogenic activities, including bat souvenirs trade that recently reported by Lee et al. (2015) on Oryx. To further understand bat souvenir trade in the country, we...

To date, three species of the genus Glischropus are recognized from the Indomalayan zoogeographic region—G. bucephalus from the Indochinese subregion, G. tylopus from the Sundaic subregion (Peninsular Thailand and Malaysia, Borneo, Sumatra, Moluccas) and G. javanus, restricted to Java. The investigation of the holotype and three topotype specimens...

Understanding distribution patterns and multitrophic interactions is critical for managing bat- and bird-mediated ecosystem services such as the suppression of pest and non-pest arthropods. Despite the ecological and economic importance of bats and birds in tropical forests, agroforestry systems, and agricultural systems mixed with natural forest,...

Bukit Barisan Selatan National Park is one of the last refuges protecting intact forest and a representative mammalian fauna in Sumatra. However, knowledge of bat diversity in the area is limited. From 2010 to 2012, 47 bat species were recorded through a series of surveys in 12 localities within and around the national park. An additional six speci...
