摘要: Thirty colonies of the Marsh Fritillary (Euphydryas aurinia) have recently been recorded in Western Bohemia, Czech Republic. The majority are small, their total area 1.5 km2. Small size and intensive grazing/mowing were positively associated with observed declines/extinctions, while abandonment threatens longer term. Short distances to nearest buffered against declines. High colony turnover, asynchronous local dynamics pointed species’ biotope requirements all point a dynamic metapopulation structure; patterns connectivity revealed that there several metapopulations within region. Because conserving species its extant sites seems unsustainable long term, restoration habitats is proposed.
