Description

Spiders (Arachnida: Araneae) are a classic indicator taxon for evaluating the health of natural environments. However, studies of spiders’ responses to forest succession under natural and anthropogenic disturbance regimes are lacking. Yakushima Island in southwestern Japan has a unique forest ecosystem, and part of the island is designated as a world natural heritage site by UNESCO. Approximately 90% of Yakushima is covered by forest, including both plantations and natural forests. We made an inventory of spiders on Yakushima Island by collecting specimens in five forests (two plantations and three natural forests) with Malaise and window traps from 2006 to 2008 (a total of 637 traps). We collected 3487 specimens, representing 31 families and 165 species or morphotypes, including undescribed and unidentified species. All specimens were preserved in 70% ethanol, and all data were gathered into a Darwin Core Archives as sample event data. The data set is available from the GBIF network (http://osawa.nomaki.jp/dl/dwca-yakushima_spyder01-v1.0.zip /upload from JBIF node after acceptance). Because there have been no spider inventories based on such a systematic trapping survey in Japan, this data set provides new insight into the biodiversity on Yakushima Island.

Couverture géographique

The census was conducted in three regions on Yakushima: Aikodake, with both natural (30.381°N, 130.627°E) and cedar plantation forest (30.384°N, 130.627°E); Kankake, with Japanese cedar plantation forest (30.381°N, 130.412°E); Han-yama, with natural forest (30.364°N, 130.389°E); and Arakawa, with natural forest (30.299°N, 130.556°E).

Couverture taxonomique

In total, 3487 individuals belonging to 162 species, including morphotypes from 31 families, were collected during the censuses. Of these collections, two records have already been published as papers. Baba et al. 2016, Baba et al. 2015 All specimens were identified by the authors according to Ono 2009 and scientific names were determined according to the World Spider Catalog Natural History Museum 2017. If we could not obtain sufficient information for proper identification, we determined the order, family, and genus of each species on the basis of the relevant morphotypes. Thus, some records have only order, family, or genus rank for the taxonomic information. The species name genus and family sequence are arranged in alphabetical order. Order: Araneae Family: Agelenidae, Anyphaenidae, Araneidae, Atypidae, Clubionidae, Ctenidae, Ctenizidae, Dictynidae, Eutichuridae, Gnaphosidae, Leptonetidae, Linyphiidae, Liphistiidae, Lycosidae, Miturgidae, Mysmenidae, Oonopidae, Oxyopidae, Philodromidae, Phrurolithidae, Pimoidae, Pisauridae, Salticidae, Segestriidae, Sparassidae, Tetragnathidae, Theridiidae, Theridiosomatidae, Thomisidae, Zodariidae.

Méthodes d'échantillonnage

A Townes-type Malaise trap and IBOY-type window trap were used for sampling spiders. These types of trap are suited to a monitoring program in forest habitat because they capture a wide range of spiders, excluding some ground-dwelling forms. The Malaise trap had openings with a height of 1.8 m and a length of 1.8 m on both sides, and the attached bottles contain a mixture of 70% ethanol and a small amount of ethylene glycol for fixation and preservation of samples.

Etendue de l'étude Insect traps were set at five sites in three regions: old-growth evergreen forests (Aikodake and Han-yama) and neighboring 40-year-old Japanese cedar (Cryptomeria japonica) plantation forests (Aikodake and Kankake) in the low mountainous region (150-250 m elevation), and an old-growth mixed forest (Arakawa) higher in the mountains (1200 m elevation). The old-growth evergreen forest and the Japanese cedar plantation in Aikodake are part of a continuous forest, and they are only 100 m away from each other.

Description des étapes de la méthode:

  1. Three Malaise traps were set at each study site at intervals of about 20 m (15 in total). Malaise traps were set continuously from July 2006 to March 2008, and samples were collected about once every month. The IBOY window trap consists of crossed transparent acrylic collision boards on a yellow bucket with a diameter of 36 cm, in which 1.5 L of water containing 10 ml of neutral detergent and 10% acetic acid aqueous solution is placed. We hunged these window traps at a height of about 30 cm above the ground. The window traps were set for 3 days in the latter half of each month from July 2006 to February 2008. The samples collected by each trap were brought back to the laboratory, and spiders were identified and counted.
