The newest spatial distribution out-of grasslands could be essential for maintaining bumble bee range

Significant result of maximum R several regression data of landscape parameters (500- and you will 700-meters radii toward bumble-bee diversity and you will variety per hour

Matchmaking ranging from bumble bee variety at that web site while the LRI of grasslands related not including the prairie data website inside a location which have a distance regarding (a) 500 and you can (b) 700 meters. Pick Table dos to own surroundings categories within the grasslands group.

The addition of abundance from bumble-bee made use of ramets during the webpages towards the model only some improved the fresh new difference informed me ( Fig

Partitioning of variance between land and you can regional details during the several regression activities on radii from 500 and you can 700 m. (a) Difference inside the bumble-bee range partitioned ranging from LRI out-of grasslands and you will local webpages variety. (b) Variance by the bucket load off bumble bees trapped each time partitioned ranging from portion of grassland in the surroundings (instead site) and you can local web site abundance.
