Description

During a field course on spider taxonomy and ecology at the University of Helsinki we had the opportunity to sample four plots with a dual objective of both teaching on field methods, spider identification and behaviour, and uncovering the spider diversity patterns found in the southern coastal forests of Hankoniemi. As an ultimate goal, this field course intended to contribute to a global project that intends to uncover spider diversity patterns worldwide (see http://biodiversityresearch.org/research/biogeography/). With that purpose, we followed a set of standardized methods and procedures that allow the comparability of obtained data with numerous other samples being conducted across all continents. By doing so we guarantee that this data will be reused for multiple future projects currently being implemented.

Sampling Description

Study Extent

Four 50x50m plots following a West to East transect were selected for sampling. All were in mixed coastal forests dominated by Norway spruce and Scots pine at sea level (0 - 10 m). Plots 1 and 2 were separated by about 100 m, plot 3 was 1.8 km and plot 4 was 5 km from the first.

Sampling

We followed the COBRA - Conservation Oriented Biodiversity Rapid Assessment protocol at the four plots. This protocol, first proposed for Mediterranean spiders and very recently adapted for and being applied both on the tropics and islands involves night aerial sampling (4 hours/plot), day/night sweeping (4 hours/plot), day/night beating (4 hours/plot) and pitfall traps (48 traps distributed for 12 samples). In total it involves about 24 hours of effective work per site.
