BIOFRAG - a new database for analyzing BIOdiversity responses to forest FRAGmentation

Area of Science:

• Ecology
• Conservation Biology
• Biodiversity Science

Background:

• Habitat fragmentation research yields complex, inconsistent results due to varied methodologies and data.
• Synthesizing findings is challenging without standardized data collation and access.
• A unified approach is needed to analyze biodiversity responses to fragmentation.

Purpose of the Study:

• To present a novel relational database for collating and standardizing primary biodiversity data from habitat fragmentation studies.
• To link field data with taxonomic, spatial, temporal, and environmental information for robust analysis.
• To facilitate large-scale syntheses and re-examinations of fragmentation impacts.

Main Methods:

• Development of a relational database linking field data (species presence, abundance, ground cover) to plot attributes.
• Inclusion of taxonomic nomenclature, spatial and temporal plot details, and environmental characteristics.
• Data compilation from 58 landscapes across six biogeographic realms, encompassing diverse taxa.

Main Results:

• The database contains 9,830 unique species records from 58 landscapes.
• Includes data on mammals, birds, insects, plants, fungi, and more, with 711 species found in multiple landscapes.
• Features three long-term time-series datasets (>10 years).

Conclusions:

• The standardized database enables consistent data retrieval and analysis of biodiversity responses to fragmentation.
• Facilitates testing generalizations across diverse systems and taxa, and addressing methodological challenges like pseudo-replication.
• Supports broad syntheses of land-use effects and encourages ongoing data contributions for dynamic updates.
