Description

The dataset represents spiders' abundance and species composition in the agricultural landscape of the Gera district in the Oromia Region, southwest Ethiopia. They were collected from 40 home gardens from May to September 2011. The specimens were collected using pitfall traps during two separate months and related sample composition to land use in the vicinity (1 ha plot, local scale, field data) and tree cover within 200 and 500 m radius zones (landscape scale, satellite data). The highest spider abundances were found when either the home garden or the surrounding had high tree cover and were lower in both the most tree-rich and tree-poor landscape-garden combinations. 

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 40 records.

1 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.

Project Data

This project aims to extend the work initiated in 2017 by the EU-funded GBIF Biodiversity Information for Development project BIDERSE and to address challenges by providing capacity-building training and knowledge transfer, enabling stakeholders to mobilize, manage, and use data according to global best practices. The key stakeholders identified for establishing a national biodiversity platform will act as a basis for this initiative.

Sampling Methods

A total of 40 home gardens were investigated that varied in local tree cover and were situated at different distances from forest edges. After locating each home garden using a handheld GPS and maps, six plastic pitfall traps (8 cm diameter and 6 cm deep) were installed. Traps were placed at 1 m intervals and connected by a guide-vane (5 cm 9 1 m) to enhance trapping efficiency. Traps were covered with a plastic plate roof, supported by nails from the side, to prevent rain from entering. During the first week after installation, traps were closed with lids to reduce ‘digging-in effects’ (Digweed et al. 1995). When the trapping started, the cups were partially filled (ca ) with a 5 % acetic acid solution, which served both as an attractant and preservative (Woodcock 2005). The traps were emptied and refilled with fresh acetic acid every 4–7 days in each home garden during the periods 11 May to 11 June and 18 August to 14 September 2011. All specimens were transferred to vial tubes with 70 % alcohol for later identification.

Study Extent The data were collected from Gera district, Oromia region, southwest Ethiopia.

Method step description:

  1. The specimens were collected using pitfall traps during two separate months. It examined how different land-use types and forest cover at different scales influenced the abundance and species composition of spiders in 40 home gardens in southwest Ethiopia.
