Standardised spider (Arachnida, Araneae) inventory of Lammi, Finland

2020

In June 2019, an ecology field course of the University of Helsinki was held at Lammi Biological Station, Southern Finland. Within this course, the students familiarised themselves with field work and identification of spiders and explored the diversity of species in the area. Three sampling plots were chosen, one in grassland and two in boreal forest, to demonstrate the sampling techniques and, by applying a standardised protocol (COBRA), contribute to a global spider biodiversity project. The collected samples contained a total of 3445 spiders, of which 1956 (57%) were adult. Only adult spiders were accounted for in the inventory due to the impossibility of identification of juveniles. A …

Standardised spider (Arachnida, Araneae) inventory of Kilpisjarvi, Finland

2020

Abstract Background A spider taxonomy and ecology field course was organised in Kilpisjarvi Biological Station, northern Finland, in July 2019. During the course, four 50 × 50 m plots in mountain birch forest habitat were sampled following a standardised protocol. In addition to teaching and learning about spider identification, behaviour, ecology and sampling, the main aim of the course was to collect comparable data from the Kilpisjarvi area as part of a global project, with the purpose of uncovering global spider diversity patterns. New information A total of 2613 spiders were collected, of which 892 (34%) were adults. Due to uncertainty of juvenile identification, only adults are includ…

Territoriality in the Sheet-Web Spider Linyphia triangularis (Clerck) (Araneae, Linyphiidae

2010

Zusammenfassung 1 Das adulte L. triangularis-♂ bleibt bis zu 2 Tagen im Netz eines ♀, betrachtliche Zeit verbringt es von Netz zu Netz wandernd. Wahrend der Zeit des gemeinsamen Netzaufenthaltes ist das ♂, ob das ♀ nun kopulationsbereit ist oder nicht, stets der dominante Teil des Paares. 2 Wenn mehrere ♂♂ im ♀-Netz zusammentreffen, zeigen sie Droh- und Kampfverhalten, in dem die vergroserten Chelizeren und Klauen benutzt werden. Mehrere Stufen des Kampfverhaltens werden beschrieben und als Aggressionsanzeiger betrachtet. 3 Netzreduktion durch das ♂ wird als Methode zur Verhinderung von Storungen wahrend der Kopulation betrachtet. Selektionsmechanismen, die die Evolution solchen Verhaltens …
