African forest elephant movements depend on time scale and individual behavior

Area of Science:

• Ecology and Conservation Biology
• Wildlife Movement Ecology

Background:

• African forest elephants (Loxodonta cyclotis) are critically endangered and crucial for Afrotropical forest ecosystems.
• Understanding drivers of elephant movement and behavior at landscape scales is vital for conservation but currently limited.

Purpose of the Study:

• To analyze GPS data from 96 African forest elephants in Gabon.
• To determine how five movement behaviors vary across scales and are influenced by environmental and anthropogenic factors.
• To investigate evidence for behavioral syndromes in elephant movement.

Main Methods:

• Utilized GPS tracking data from 96 African forest elephants across Gabon.
• Analyzed five distinct movement behaviors at varying spatial scales.
• Assessed the influence of anthropogenic and environmental covariates on movement patterns.

Main Results:

• Identified an 'idler' to 'explorer' behavioral syndrome axis, where more mobile elephants have larger home ranges and exhibit more exploratory movements.
• Observed significant inter-individual variation in movement behaviors within these syndromes.
• Highlighted that individual differences in movement create conservation challenges.

Conclusions:

• African forest elephant movement exhibits syndromes but with substantial individual variation.
• Conservation strategies must account for this inter-individual variability for effective protection of Loxodonta cyclotis.
• Further research into movement ecology is essential for endangered species management.
