Combinations of reproductive, individual, and weather effects explain torpor patterns among female little brown bats (Myotis lucifugus)

Besler, Nicole K. (Halifax, N.S. : Saint Mary's University, 2018)

Torpor is a thermoregulatory strategy used by some small mammals to, in part, conserve energy during poor weather conditions and limited food. Some mammalian females may use torpor throughout reproduction, however, there ...
Distribution of the eastern pipistrelle (Perimyotis subflavus) in southwest Nova Scotia relative to landscape factors

Farrow, Lesley J. (Halifax, N.S. : Saint Mary's University, 2007)

The eastern pipistrelle ( Perimyotis subflavus ) in Nova Scotia has a restricted range, exhibits distinct behavioral characteristics, and is likely isolated from conspecific populations. In the region they require clumps ...
Do little brown bats (Myotis lucifugus) use conspecific calls and odours to find new roosts?

Appleby, Karissa (Halifax, N.S. : Saint Mary's University, 2016)

I tested the hypothesis that conspecific calls and odours would attract little brown bats (Myotis lucifugus) to new roosts. I predicted bats would discover and use treatment boxes before control boxes. I built six new bat ...
Factors affecting the distribution and roost-site selection of bats on the island of Newfoundland

Park, Allysia C. (Halifax, N.S. : Saint Mary's University, 2010)

Ecological studies at the periphery of a species' distribution provide an opportunity to explore the limits of population viability under unique conditions. Research regarding specific factors that limit temperate bat ...
Genetic population structure within and among little brown bat (Myotis lucifugus) maternity colonies within mainland Nova Scotia, Canada

Arseneault, Krista (Halifax, N.S. : Saint Mary's University, 2013)

A common trait among mammals is group living, where individuals come together as a temporary or permanent group. In little brown bats (Myotis lucifugus), this is a common behavior of hibernation and at maternity roosts. ...
Movement dynamics of the little brown bat (Myotis lucifugus) and the northern long-eared bat (Myotis septentrionalis) in Nova Scotia

Segers, Jordi Leon (Halifax, N.S. : Saint Mary's University, 2014)

Two resident bat species in Nova Scotia are the little brown bat (Myotis lucifugus), an aerial hawker, and the northern long-eared bat (M. septentrionalis), a forest gleaner. Little is known about their local movement ...
Roosting and social ecology of the tricolored bat, Perimyotis subflavus, in Nova Scotia

Poissant, Joseph Andrew (Halifax, N.S. : Saint Mary's University, 2009)

Combinations of abiotic and biotic factors influence the behavior and evolution of a species. Temperate bats are constrained by inhospitable winters, hibernation requirements and interspecific competition for resources, ...
Social ecology of the northern long-eared bat (Myotis septentrionalis)

Garroway, Colin James (Halifax, N.S. : Saint Mary's University, 2006)

A population's social system influences its mating patterns, the spatial and temporal distribution of individuals, their dispersal, and consequently the distribution of alleles, thereby affecting its evolutionary trajectory. ...
Social structure, emergence behaviour and roost switching in female little brown bats (Myotis lucifugus)

Irwin, Alicia (Halifax, N.S. : Saint Mary's University, 2014)

The evolution of sociality involves trade-offs between benefits (e.g. protection from predation, information transfer) and costs (e.g. transfer of disease, competition). This study investigated the potentially social ...
Subtle population structuring found within northern long-eared bats (Myotis septentrionalis) inhabiting mainland Atlantic Canada

Johnson, Laura N. L. (Halifax, N.S. : Saint Mary's University, 2014)

Delineating the connections between seasonal sites is required to effectively manage migratory species. One method to characterize the connectivity among populations is to assess the genetic similarity between individuals ...
Swarming behaviour and fall roost-use of little brown (Myotis lucifugus), and northern long-eared bats (Myotis septentrionalis) in Nova Scotia, Canada

Lowe, Amanda J. (Halifax, N.S. : Saint Mary's University, 2012)

Temperate bats exhibit a poorly understood behaviour during the fall known as swarming, which has both survival and reproductive consequences. The goal of this project was to characterize how variation in physical conditions ...
The effects of forest fragmentation on the forest-dependent northern long-eared bat (myotis septentrionalis)

Henderson, Lynne E. (Halifax, N.S. : Saint Mary's University, 2007)

The modification of formerly contiguous natural areas is a central concern to conservation biology because of the potential to negatively affect biological communities. Characterizing the effects of forest fragmentation ...
What they do in the shadows : stable isotope analysis reveal that spatial and temporal heterogeneity explain dietary niche variation in Myotis lucifugus in Newfoundland

Fouts, Cody Randall (Halifax, N.S. : Saint Mary's University, 2018)

Individuals must balance competitive and environmental pressures with obtaining the nutrients necessary to survive and reproduce. The goal of this project was to infer on individual dietary adaptations of adult female ...
