A new tool to quantify biodiversity change under landscape transformation

Area of Science:

• Ecology
• Conservation Biology
• Landscape Ecology

Background:

• Understanding biodiversity shifts in landscapes with varied natural and anthropized environments is crucial for effective conservation management.
• Existing methods may not fully capture biodiversity dynamics across multiple habitat types and diversity dimensions.

Purpose of the Study:

• To introduce a novel algorithm for assessing biodiversity changes in landscapes with varying proportions of multiple habitat types.
• To provide a flexible tool capable of evaluating taxonomic, functional, and phylogenetic diversity.

Main Methods:

• The algorithm resamples individuals from different habitats, considering habitat proportions and recorded individuals.
• It calculates diversity based on sampled individuals and can incorporate phylogenetic or functional data.
• The procedure is repeated with varied habitat proportions to simulate landscape changes.

Main Results:

• The method successfully assessed biodiversity changes in simulated scenarios and an empirical bat dataset.
• It accurately reflected expected biodiversity patterns across different habitat mixes.
• The tool demonstrated its capability to handle multiple habitat types and diversity dimensions.

Conclusions:

• The developed method is a valuable tool for biodiversity assessment in landscape planning.
• It supports the creation of more sustainable landscapes by accounting for complex habitat compositions.
• The approach enhances conservation strategies by providing insights into biodiversity responses to landscape changes.
