02Description

Species Profile

Gongylidiellum murcidum, commonly known as the tykkfingeredderkopp, is a small sheet weaver spider belonging to the family Linyphiidae. This diminutive arachnid is characterized by its distinctive morphological features and specialized ecological requirements. The species inhabits specific microhabitats within terrestrial ecosystems, where it constructs characteristic sheet webs to capture small arthropod prey. Like many members of its family, G. murcidum plays an important role in local food webs as both predator and prey. The species has been classified as Critically Endangered by the IUCN, indicating an extremely high risk of extinction in the wild. This conservation status reflects significant concerns about the species' long-term viability, though the population trend remains unknown due to limited monitoring data. The primary threats to G. murcidum likely include habitat loss and degradation, which are common factors affecting many small invertebrate species with restricted distributions. Climate change may also pose additional risks through alterations to the specific environmental conditions required by this species. Conservation efforts for G. murcidum are likely constrained by the limited knowledge of its ecology, distribution, and population dynamics. Effective conservation strategies would require detailed field surveys to better understand the species' habitat requirements, population status, and specific threats. Protection of remaining suitable habitat and broader ecosystem conservation measures may be critical for the species' survival.

The tykkfingeredderkopp faces threats primarily from habitat loss and degradation of its specialized microhabitat requirements. Climate change may further impact the species through alterations to environmental conditions necessary for its survival.
