Meetnetten.be - Larvae and metamorph counts for Amphibia in Flanders, Belgium

最新版本 由 Research Institute for Nature and Forest (INBO) 發佈於 Oct 28, 2020 Research Institute for Nature and Forest (INBO)

Meetnetten.be - Larval and metamorph counts for Amphibia 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 site counts for 3 priority species (Triturus cristatus, Hyla arborea, Pelobates fuscus), as well as other amphibian species observed during sampling. 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), maximum depth, number of sweeps, pH, presence of fish, shading, pond surface, permanent water column and water quality at the time of the event (in the measurement or fact extension) and for each occurrence an occurrenceID, the number of recorded individuals, status (present/absent) 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 154 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)
    154
  • MeasurementOrFact 
    1326
  • Occurrence 
    745

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.

研究區域描述 Flanders, Belgium
研究設計描述 Each monitoring network consists of fixed sample locations in which target species are 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

In June - mid-July, larvae are counted to determine reproductive success. In order to quantify the larvae present, a net should be dipped per 2 m of shoreline (where possible and suitable). Each two-metre piece (one dip movement), the number of larvae is noted. In total, you feed a minimum of 5 and a maximum of 30 scoop movements. Sampling was done using the protocol described in De Bruyn et al. (2015), updated by Speybroeck et al. (2020), and explained to volunteers in Lewylle et al. (2017).

研究範圍 1. Triturus cristatus, or the great crested newt, is our largest native newt. It is widespread in Flanders, especially in wide river valleys and in locations with (many) old bomb pits. Although the crested newt appears to react positively to the construction of new pools near existing populations in nature reserves, it seems to be declining in the outlying area. This species prefers fish-free pools with sun-drenched banks and rich underwater vegetation located in a varied terrestrial habitat. These include cattle drinking pools in meadows with many small landscape elements, large (spring) pools in more wooded habitats, cut-off rivers, but also old quarries. 2. Pelobates fuscus, or the common spadefoot toad, is found in fishless cattle drinking pools and relatively nutrient-rich ponds, but also in cut brook and river meanders in a fairly open, sandy environment. These are often water features in (buffered) heathlands, but also near dikes and even vegetable gardens and extensively managed fields. This type of habitat is rare in Flanders. The common spadefoot currently only occurs in the central part of Limburg. 3. Hyla arborea, or the common tree frog, is found in the scrubland of the Limburgse Kempen, a restricted section of the Antwerpse Kempen near the Belgian-Dutch border, and the dunes of the Zwin. In recent years, the Flemish population has increased.
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 with an occurrence extension
  6. The Darwin Core views are connected to the INBO IPT and documented with metadata.
  7. The dataset is published and registered with GBIF.
