Sampling flying bats with thermal and near-infrared imaging and ultrasound recording: hardware and workflow for bat point counts.

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 echolocating bat calls, and a near-infrared camera and LED illuminator to photograph bat morphology.

ChiroVox: a public library of bat calls.

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.

Bat point counts: A novel sampling method shines light on flying bat communities.

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 taxonomic resolution of this elusive taxon with minimal sampling bias. We conducted bat point counts with a sampling rig combining a thermal scope to detect bats, an ultrasound recorder to obtain echolocation calls, and a near-infrared camera to capture bat morphology.

Flower-visiting insects of genus (Myrtales: Melastomataceae) at the Fushan Botanical Garden, Taiwan.

Background: We investigated the diversity and behaviour of insects that visit flowers of four native (Family Melastomataceae) species of Taiwan and a horticultural hybrid species at the Fushan Botanical Garden, Taiwan biweekly from May to August 2020. Visits of flower-visiting insects were classified into seven behavioural categories, based on the insects' behaviour and positions on the flower. The data are further assigned into four insect-flower interactions, namely pollination, herbivory, commensalism and neutralism.

The systematic position of Hypsugo macrotis (Chiroptera: Vespertilionidae) and a new record from Peninsular Malaysia.

The Southeast Asian species of Hypsugo are rare bats, except for H. cadornae and H. pulveratus, which are distributed throughout the Indomalayan region.

Thumb-pads up-a new species of thick-thumbed bat from Sumatra (Chiroptera: Vespertilionidae: Glischropus).

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.
