| distribution of mercury in archived fur from little brown bats across atlantic canada. | total mercury (hg) concentrations were measured in archived fur from adult female little brown bats sampled at maternity roosts across atlantic canada. mercury concentrations varied significantly among regions and roosts. bats from nova scotia and newfoundland had the highest median hg concentrations (9.67 μg/g and 9.51 μg/g) among regions, and individuals from kejimkujik national park had the highest hg (median: 28.38 μg/g) among roosts. over one third of individuals sampled had fur hg concentr ... | 2015 | 26340299 |
| carbon (δ13c) and nitrogen (δ15n) stable isotope signatures in bat fur indicate swarming sites have catchment areas for bats from different summering areas. | migratory patterns of bats are not well understood and traditional methods to study this, like capture-mark-recapture, may not provide enough detail unless there are many records. stable isotope profiles of many animal species have been used to make inferences about migration. each year myotis lucifugus and m. septentrionalis migrate from summering roosts to swarming caves and mines in the fall, but the pattern of movement between them is not well understood. in this study, fur δ13c and δ15n val ... | 2015 | 25923696 |
| mercury in little brown bat (myotis lucifugus) maternity colonies and its correlation with freshwater acidity in nova scotia, canada. | insectivorous little brown bats are exposed to elevated concentrations of mercury (hg) through their preference for aquatic-based prey. here we investigated spatial patterns of total hg (thg) in fur from 10 little brown bat maternity colonies across nova scotia, and assessed relationships with the acidity of nearby lakes and rivers. total hg concentrations were measured in fur samples from 149 adult female little brown bats. values showed significant variation among colonies (mean range 3.76-27. ... | 2015 | 25591047 |
| the diet of myotis lucifugus across canada: assessing foraging quality and diet variability. | variation in prey resources influences the diet and behaviour of predators. when prey become limiting, predators may travel farther to find preferred food or adjust to existing local resources. when predators are habitat limited, local resource abundance impacts foraging success. we analysed the diet of myotis lucifugus (little brown bats) from nova scotia (eastern canada) to the northwest territories (north-western canada). this distribution includes extremes of season length and temperature an ... | 2014 | 24274182 |
