Bat diversity data collected primarily from Cat Ba Island and Lang Son Province with occasion records from Ha Noi TP.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 64 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage

Cat Ba Island, Lang Son Province, Ha Noi TP in the northeastern Vietnam

Bounding Coordinates South West [20.745, 105.801], North East [21.67, 107.052]

Taxonomic Coverage

All bats were identified to species. at least 16 species belonging to 8 genera of 6 families of bats (Mammalia: order Chiroptera) are reported. However, there are a few with identification uncertainty due to the restriction of taxonomy dilemma in the study area

Temporal Coverage

Formation Period 2017 April-2017 November

Project Data

With 380 species, bats make up nearly 40% of Southeast Asia’s mammal species but have received limited attention in biodiversity studies. To redress this, Southeast Asian Bat Conservation Research Unit (SEABCRU, developed a database for bat locality data across SE Asia. The database is a full implementation and designed to push new records to GBIF. The database has c. 40K records including cleaned and manually georeferenced GBIF records, data from literature, museums and field notes. Our prior research shows that SE Asian bat data in open-source resources are strongly biased taxonomically, spatially, and ecologically with consequences for models that underpin conservation policy. Of note is the lack of data for open-space insectivorous species that forage in non-forested habitats. Despite comprising over 30% of SE Asian bat diversity, these species are hard to record using conventional methods. However, occurrence data for these bats can be generated through acoustic sampling, but this requires a dedicated call database. In our review, call descriptions from over 40% of the 270 echolocating species have been reported in literature, but none of the recordings are accessible and many of the species occurrences attached are not published. The Hungarian Natural History Museum (HNHM, has recently received government support to develop the Asian Bat Call Database (ABCD). To fill current gaps in bat diversity in GBIF, we will (1) integrate the occurrence and acoustic databases to capture species occurrence data represented by acoustic recordings, (2) train researchers to assemble and format existing data following the Darwin Core standard through workshops, webinars and development of tools, (3) publish completed datasets to GBIF. We are confident that with additional support from GBIF, we could properly address the issues listed through the proposed activities and elevate the impact of GBIF network to biodiversity research in Southeast Asia

Sampling Methods

Bats were captured using mist nets and harp traps and, then released after reference calls were taken using a digital audio recorder.

Study Extent This data set is one of data assembled through the BIFA04_24 Project, which covered primarily SE Asia and nearby countries, e.g. Taiwan. This particular data is focused on the northeastern part of Viet Nam, including Cat Ba Island, part of the Lang Son Province and Ha Noi City
Quality Control The data were first assembled in a standard form designed for the Asian Bat Call Database (ABCD).The contributor(s) has been trained via a workshop fund by a GBIF-BIFA grant to use controlled language for data entry. The contents and format have been reviewed by the BIFA04-24 project investigator, Dr. Joe Chun-Chia Huang, and the ABCD manager, Dr. Tamas Golfol, under the supervision of Dr. Gabor Csorba from Hungarian Natural History Museum and Dr. Tigga Kingston from Southeast Asian Bat Conservation and Research Unit. The taxonomy of the species records has been carefully reviewed by Dr. Gabor Csorba which is very experienced of bat taxonomy in Asia. After all reviews and data cleaning, the data is migrated and reformatted using Darwin Core with support from the help desk (Miss Melissa Liu) of Taibif.

Method step description:

  1. Species data were either extracted from sound files recorded from captured animals or/and capture records in the field note.
