    Constructıng a specıes database and hıstorıc range maps for north amerıcan bumblebees (bombus sensu stricto latreılle) to ınform conservatıon decısıons
    (Uludağ Üniversitesi, 2009) Koch, Jonathan B.; Strange, James P.
    Bumblebees (Bombus Latreille 1802) are important native pollinators in North America. However, in the last decade at least six North American Bombus have experienced significant range contraction or population declines. A major limitation to studying species declines is the level of knowledge of historic occurrences and abundance. Here we review the current status of a bumblebee subgenus in North America, Bombus sensu stricto Latreille 1801, and present a method for generating a database and probable historic range maps from multiple museum collections. These databases and range maps can be useful tools when facilitating monitoring programs for at risk species.
