| cytological variation and pathogenicity of the bumble bee parasite nosema bombi (microspora, nosematidae). | in three field seasons, 2003-2005, bumble bees were collected in southern sweden and eastern denmark in search of microsporidian parasites. of the 16 bumble bee species studied, microsporidia were found in bombus hortorum, bombus hypnorum, bombus lapidarius, bombus lucorum, bombus pascuorum, bombus pratorum, bombus ruderarius, bombus subterraneus and bombus terrestris. only one microsporidian species, nosema bombi, was recorded. a microsporidium found in b. pratorum differed cytologically from m ... | 2007 | 17005191 |
| biosecurity for translocations: cirl bunting (emberiza cirlus), fisher's estuarine moth (gortyna borelii lunata), short-haired bumblebee (bombus subterraneus) and pool frog (pelophylax lessonae) translocations as case studies. | exposure to parasites in conservation translocations increases the risks to recipient and translocated populations from disease, and therefore there has been interest in implementing biosecurity methods. using four case examples we described how biosecurity was applied in practical translocation scenarios prior to and during a translocation and also post-release. we implemented biosecurity, including quarantine barriers, at specific points in the translocation pathway where hazards, identified b ... | 2017 | 27491684 |
| bringing back a healthy buzz? invertebrate parasites and reintroductions: a case study in bumblebees. | reintroductions can play a key role in the conservation of endangered species. parasites may impact reintroductions, both positively and negatively, but few case studies of how to manage parasites during reintroductions exist. bumblebees are in decline at regional and global scales, and reintroductions can be used to re-establish extinct local populations. here we report on how the risks associated with parasites are being managed in an ongoing reintroduction of the short-haired bumblebee, bombu ... | 2017 | 26732074 |
| reconstructing demographic events from population genetic data: the introduction of bumblebees to new zealand. | four british bumblebee species (bombus terrestris, bombus hortorum, bombus ruderatus and bombus subterraneus) became established in new zealand following their introduction at the turn of the last century. of these, two remain common in the united kingdom (b. terrestris and b. hortorum), whilst two (b. ruderatus and b. subterraneus) have undergone marked declines, the latter being declared extinct in 2000. the presence of these bumblebees in new zealand provides an unique system in which four re ... | 2011 | 21645159 |
