Meetnetten.be - Exuviae counts for dragonflies in Flanders, Belgium

最新版本 由 Research Institute for Nature and Forest (INBO) 發佈於 Oct 29, 2020 Research Institute for Nature and Forest (INBO)

Meetnetten.be - Exuviae counts for dragonflies in Flanders, Belgium is a sampling event dataset published by the Research Institute of Nature and Forest (INBO). It is part of the Meetnetten.be suite of monitoring networks for priority species in Flanders, in which data are collected at fixed locations using a standardized protocol (https://meetnetten.be). This dataset contains exuviae (larval skin remained behind after ecdysis) counts for 1 priority dragonfly species (Gomphus flavipes). Here it is published as a standardized Darwin Core Archive and includes for each sampling event an eventID, date, location and sampling protocol (in the event core), the length of the transect (in the measurement or fact extension) and for each occurrence an occurrenceID, the number of recorded individuals, status (present/absent), life stage, sex and scientific name (in the occurrence extension). Issues with the dataset can be reported at https://github.com/inbo/meetnetten-occurrences/issues

Generalized and/or withheld information: as these are sensitive priority species, location information is generalized to 1, 5 or 10 km Universal Transverse Mercator (UTM) grid cells. Original locations are available upon request.

We have released this dataset to the public domain under a Creative Commons Zero waiver. We would appreciate it if you follow the INBO norms for data use (https://www.inbo.be/en/norms-data-use) when using the data.

Data Records

The data in this sampling event 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 245 records. 2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

  • Event (核心)
    245
  • Occurrence 
    735
  • MeasurementOrFact 
    540

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.

計畫資料

Meetnetten.be is a suite of monitoring networks through which the Flemish Government is collecting high-quality information on 65 priority plant and animal species. These are species on which Flanders has to report to Europe in the framework of the Habitats and Birds Directives, but also other species that are important for the Flemish nature policy.

計畫名稱 Meetnetten.be
辨識碼 meetnetten.be
經費來源 Flemish Government
研究區域描述 Flanders, Belgium
研究設計描述 Each monitoring network consists of fixed sample locations in which the target species is counted based on a standardized protocol. Data collection relies mainly on specialized volunteers, coordinated by the NGO Natuurpunt Studie. Fieldwork is planned and monitored with the web tool https://meetnetten.be, which is also used for entering the collected data.

取樣方法

Sampling was done using the protocol described in De Knijf et al. (2019) and explained to volunteers in Ledegen et al. (2017). 1. Gomphus flavipes (River Clubtail/ Rivierrombout): During a count of larval skins, the riparian bank is slowly crossed over a length of 500 m and every larval skin found is collected. The location is preferably read with a GPS. Each transect is visited once every 10 days and this in the period from 1 June to 15 August (6 visits in total).

研究範圍 1. Gomphus flavipes (River Clubtail / Rivierrombout) occurs in medium-sized to large rivers, preferably with sandy substrate. The habitat of the Flemish population is somewhat different as the species reproduces her in a busy canal with concrete banks (De Knijf et al. 2013). We follow up on this species by counting the larval skins.
品質控管 Data are collected using a predefined sampling protocol.

方法步驟描述:

  1. Researchers from INBO and Natuurpunt Studie define and document the appropriate sampling protocol for the target species.
  2. Fieldwork is planned and coordinated by Natuurpunt Studie, using https://meetnetten.be.
  3. Data are collected in the field by specialized volunteers, using the predefined sampling protocol.
  4. Volunteers enter the collected data in https://meetnetten.be.
  5. A custom SQL view is created in the meetnetten.be database to map the original data to Darwin Core as an event core, occurrence extension and measurement or fact extension.
