“…Bumble bee conservation initiatives designed to curb these declines should include actions that establish, enhance, and maintain habitat. The declining B. fraternus and B. pensylvanicus persist in northeast Texas, where a substantial area of native rangeland remains (Beckham et al, 2016); across the state, native rangelands comprise approximately 63% of the state's nonfederal rural land (U.S. Department of Agriculture, 2013), and encouraging the conservation of these lands amidst rapid population growth and urbanization may prove beneficial to bumble bees. Additionally, practices such as targeted agri-environment schemes that increase floral biodiversity have been shown to increase bumble bee diversity and abundance in agricultural systems (Pywell et al 2006;Carvell et al 2007;Carvell et al 2011) and, within urban environments, green spaces such as parks and community gardens can provide valuable habitats for bumble bees in otherwise unfavorable landscapes (McFrederick & LeBuhn, 2006;Ahrne et al, 2009;Goulson et al, 2010;.…”

“…Though bumble bee declines can be difficult to assess owing to a lack of long-term monitoring data (Berenbaum et al, 2007), some studies have suggested regional and national declines for several species whose ranges extend into Texas, including B. auricomus (Colla et al, 2012), B. fervidus (Colla & Packer, 2008;Colla et al, 2011;Colla et al, 2012), B. fraternus (Colla & Packer, 2008;Grixti et al, 2009;Hatfield et al, 2014), B. pensylvanicus (Berenbaum et al, 2007;Colla & Packer, 2008;Grixti et al, 2009;Cameron et al, 2011;Colla et al, 2011;Colla et al, 2012), and B. variabilis (Grixti et al, 2009;Colla et al, 2011;Colla et al, 2012). To our knowledge, the only recent attempt to assess the current status of Texas bumble bee populations took place in a 24-county region of northeast Texas, where five species had historically been found (Beckham et al, 2016). In that study, the results of targeted field surveys (2010-2014) were compared to natural history specimen records.…”

“…An effective species conservation program requires delineation of the distribution of the species of interest (Eken et al, 2004), as well as an understanding of their habitat. Prior to the current study, efforts to establish Texas bumble bee distributions included the compilation and mapping of Texas specimen data from natural history collections by Warriner (2012) and targeted field studies in the northeastern portion of the state (Beckham et al, 2016). Williams et al (2014) also modeled range-wide species distributions for North American bumble bees, to include Texas species.…”

Texas is the second largest state in the United States of America, and the largest state in the contiguous USA at nearly 700,000 sq. km. Several Texas bumble bee species have shown evidence of declines in portions of their continental ranges, and conservation initiatives targeting these species will be most effective if species distributions are well established. To date, statewide bumble bee distributions for Texas have been inferred primarily from specimen records housed in natural history collections. To improve upon these maps, and help inform conservation decisions, this research aimed to (1) update existing Texas bumble bee presence databases to include recent (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) data from citizen science repositories and targeted field studies, (2) model statewide species distributions of the most common bumble bee species in Texas using MaxEnt, and (3) identify conservation target areas for the state that are most likely to contain habitat suitable for multiple declining species. The resulting Texas bumble bee database is comprised of 3,580 records, to include previously compiled museum records dating from 1897, recent field survey data, and vetted records from citizen science repositories. These data yielded an updated state species list that includes 11 species, as well as species distribution models (SDMs) for the most common Texas bumble bee species, including two that have shown evidence of range-wide declines: B. fraternus (Smith, 1854) and B.pensylvanicus (DeGeer, 1773). Based on analyses of these models, we have identified conservation priority areas within the Texas Cross Timbers, Texas Blackland Prairies, and East Central Texas Plains ecoregions where suitable habitat for both B. fraternus and B.pensylvanicus are highly likely to co-occur. 15 Abstract: 16 Texas is the second largest state in the United States of America, and the largest state in the 17 contiguous USA at nearly 700,000 sq. km. Several Texas bumble bee species have shown 18 evidence of declines in portions of their continental ranges, and conservation initiatives targeting 19 these species will be most effective if species distributions are well established. To date, 20 statewide bumble bee distributions for Texas have been inferred primarily from specimen 21 records housed in natural history collections. To improve upon these maps, and help inform 22 conservation decisions, this research aimed to (1) update existing Texas bumble bee presence 23 databases to include recent (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) data from citizen science repositories and targeted field 24 studies, (2) model statewide species distributions of the most common bumble bee species in 25 Texas using MaxEnt, and (3) identify conservation target areas for the state that are most likely 26 to contain habitat suitable for multiple declining species. The resulting Texas bumble bee 27 database is comprised of 3,580 records, to include previously compiled museum records dating 28 from 1897, r...
