Spiders from Macaronesia_Madeira. Version 1.7. Universidade dos Açores. Sampling event dataset https://doi.org/10.15468/pvnmc0 accessed via GBIF.org on 2023-06-07.

Description

The data presented here comes from samples collected as part of one recent research project (MACDIV), which aimed to understand the drivers of community assembly in Macaronesian islands. We applied the sampling protocol COBRA (Conservation Oriented Biodiversity Rapid Assessment, Cardoso 2009) in twelve 50 m x 50 m native forest plots in the Madeira Island, five dry plots in Madeira Island and five dry plots in Porto Santo Island to assess the diversity of spiders species. Through this publication we contribute to the knowledge of the arachnofauna of the Madeira archipelago, and more specifically, to that of the islands of Madeira and Porto Santo. Of the 87 species and 18 morphospecies (undescribed) collected, 34 were endemic, 26 native non-endemic, 22 introduced and 23 species of unknown origin. Although most of the species had been previously recorded on both islands, 21 species are new records for Madeira island and 32 new for Porto Santo (33 for the whole archipelago).

Sampling Description

Study Extent

We established twenty-two 50 m x 50 m plots grouped according to habitat and between-plot distances. Twelve plots were located in areas covered with laurisilva, and grouped in two sets of six. Within each set, plots were placed at increasing distances from a first, reference plot: 0.1, 1, 5, 10 and 20 km (Fig. 1). The remaining 10 plots were located in areas of open dry habitat, five on Madeira island and five on Porto Santo, also at increasing distances (0.1, 1, 5 and 10 km). This design allowed to test distance decay patterns on beta diversity in a log scale for the MACDIV project.

Sampling

We applied two versions of the optimised and standardised COBRA protocol (Conservation Oriented Biodiversity Rapid Assessment) (Cardoso 2009), the one for temperate forests and the one for open habitats, to forest and dry habitat plots, respectively. The COBRA protocols have been proposed as part of standard inventorying and monitoring programs on island and continental ecosystems, and have already been used for a number of studies on spiders and beetles (Cardoso 2009, Borges et al. 2018, Malumbres-Olarte et al. 2017, Malumbres-Olarte et al. 2018). The forest COBRA protocol consisted of: four night aerial samples (1 hour / sample), two day sweeping samples and two night sweeping samples (1 hour / sample), two day beating samples and two night beating samples (1 hour / sample) and 12 pitfall samples (4 traps / sample). In addition, we collected the following samples to cover beetle diversity (Borges et al. 2018): two diurnal active aerial searching under bark, lichens and bryophytes (ABS) (1 hour / sample) and two diurnal active aerial searching in decaying trunks, dead wood on the ground and under stones (GWS) (1 hour / sample). The protocol for dry open areas was composed of: four night ground samples (1 hour / sample) and four day sweeping samples and four night sweeping samples (1 hour / sample). Sampling occurred in August 2016 (forest habitat plots of Madeira) and April 2017 (dry habitat plots of Madeira and Porto Santo).

Method steps

  1. The data has been published as a Darwin Core Archive (DwC-A), which is a standardised format for sharing biodiversity data as a set of one or more data tables. The core data table contains 562 records (eventID). One extension data table also exists with 3281 occurrences. The extension supplies extra information about the core record.
