ECOLOGICAL AND TAXONOMIC STUDY OF SAPROXYLIC BEETLES IN EUROPE
ecological and taxonomic study of saproxylic beetles in europe
OVERVIEW
This project, conducted by Nicklas, is an extensive ecological and taxonomic investigation of saproxylic beetles associated with ancient oak forests across Europe. Saproxylic beetles, which depend on dead or decaying wood for at least part of their lifecycle, are critical to forest ecosystems. This study aims to deepen the understanding of their diversity, distribution, and ecological roles, providing insights essential for their conservation.
Objectives
Document Species Diversity
Catalog the species richness of saproxylic beetles in diverse habitats across Europe.
Taxonomic Identification
Identify and describe new species, and clarify the taxonomy of existing species.
Ecological Roles
Investigate the ecological functions and interactions of saproxylic beetles within their habitats.
Geographical Patterns
Analyze how beetle diversity and ecological traits vary with latitude and other environmental gradients.
Conservation Insights
Provide data to inform conservation strategies for preserving beetle diversity and forest health.

Methodology
Methodology
Site Selection: The study encompasses 28 sites across Europe, selected for their significant populations of old hollow oak trees, which are key habitats for saproxylic beetles.
Sampling Techniques: Beetles were collected using flight interception traps installed on oak trees, capturing specimens during their active flight periods over several months.
Species Identification: Beetles were identified to the species level by experts, focusing on 11 taxonomic families and their respective feeding guilds.
Data Analysis: Statistical models were employed to examine patterns of species richness and body size in relation to latitude and other variables.
