Tracking the Trends and Spatiotemporal Variation of Marsh Fritillary on Gotland
Tracking the Trends and Spatiotemporal Variation of Marsh Fritillary on Gotland
OVERVIEW
Amanda’s master’s project focuses on the trends, population size, and spatiotemporal variation of the Marsh Fritillary (Euphydryas aurinia) on Gotland, Sweden. This species is currently listed as Vulnerable (VU) and has experienced significant fluctuations in population size due to environmental changes.
Key Objectives
Monitor Population Trends
Track the size and fluctuations of Marsh Fritillary populations over time.
Analyze Spatiotemporal Variation
Study how the population varies across different habitats and seasons on Gotland.
.
Understand Habitat Requirements
Identify critical habitat features and the impact of patch size and isolation on population stability.
Key Findings
Key Findings
Population Fluctuations: The Marsh Fritillary population on Gotland exhibits significant annual fluctuations, influenced by environmental conditions such as rainfall and temperature.
Habitat Preferences: The species thrives in open wetlands and fens with abundant host plants like Succisa pratensis (Devil’s-bit Scabious). However, habitat quality and connectivity are crucial for its survival.
Impact of Habitat Isolation: Populations in isolated habitat patches are more vulnerable to decline, emphasizing the need for connected networks of suitable habitats.
