MATRIX project, Budongo fragments birds

最新版本 由 University of Bergen 發佈於 Dec 4, 2019 University of Bergen

The connections between forest fragments around Budongo Forest Reserve in western Uganda have been extensively disturbed by agriculture and commercial plantations thereby isolating the forest fragments and the main forest. We conducted bird surveys through mist-netting in the continuous forest and six forest fragments, to evaluate the effects of different aspects of fragmentation on bird species richness and community composition.

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 46 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.

  • Event (核心)
    46
  • Occurrence 
    730

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.

取樣方法

In each site, three 400 m transects were set, perpendicular to the edge of the forest at the start point. In each 50 m section of each transect birds were trapped at two different net sites, one on each side of the transect with the larger net on the side closer to the centre point of the fragment. Each transect had a total of 24 nets and was mist netted twice. Nets were opened from 07.00 to 14.00hrs; hence each transect was mist netted for a total of 384 net hours. Mist nets were checked every hour to avoid birds injuring themselves and to protect them from predators. The time of opening and closing each net was recorded. Nets were open only on rain free days and if it threatened to rain when the nets were already out, they would be closed immediately to avoid birds getting chilled when suspended in the net. Birds captured were ringed with numbered metal rings, recorded and released close to where they were caught.

研究範圍 Sixteen (13m × 3m × 36mm) plus eight (18m × 3m × 36mm) mist nets were used to survey the understorey birds.
