Paleontology is a multi-faceted subject that involves taxonomy and community analysis as two of its cornerstones. Both qualitative and quantitative approaches have been incorporated into the various methods employed in such analyses. Each paleontologist obvious has his or her own preference that...

Biotic homogenization within and across eight widely distributed grasslands following invasion by Bromus inermis
Download2019-01-01
Stotz, G. C., Gianoli, E., Cahill, J. F.
Invasive species can alter the structure and function of the communities they invade, as well as lead to biotic homogenization across their invasive range, thus affecting large-scale diversity patterns. The mechanisms by which invasive species can lead to biotic homogenization are poorly...

Birds of a feather do not always lek together: Genetic diversity and kinship structure of Greater Sage-Grouse (Centrocercus urophasianus) in Alberta
Download2010
Aldridge, C.L., Bush, K.L., Coltman, D.W., Carpenter, J.E., Paszowski, C.A., Boyce, M.S.
Endangered species are sensitive to the genetic effects of fragmentation, small population size, and inbreeding, so effective management requires a thorough understanding of their breeding systems and genetic diversity. The Greater Sage-Grouse (Centrocercus urophasianus) is a lekking species that...

Ashley, C., Foxcroft, G., Plastow, G., Harding, J. C. S., Lunney, J. K., Ladinig, A.
The severity of porcine reproductive and respiratory syndrome was compared in pregnant gilts originating from high and low birth weight litters. One-hundred and eleven pregnant gilts experimentally infected with porcine reproductive and respiratory syndrome virus on gestation day 85 (±1) were...

Black-capped Chickadees (Poecile atricapillus) can identify individual females by their fee-bee songs

Montenegro, Carolina, Service, William D., Scully, Erin N., Campbell, Kimberley A., Sturdy, Christopher B
Individual recognition is a social behavior that occurs in many bird species. A bird’s ability to discriminate among familiar and unfamiliar conspecifics is critical to avoid wasting resources such as time and energy during social interactions. Black-capped Chickadees (Poecile atricapillus) are...

Black-capped chickadees (Poecile atricapillus) discriminate between naturally-ordered and scramble-ordered chick-a-dee calls and individual preference is related to rate of learning
Download2023-01-01
Though many forms of animal communication are not reliant on the order in which components of signals are combined to be effective, there is evidence that order does matter for some communication systems. In the light of differential responding to calls of varying note-order observed in...

The songs of many songbird species vary geographically, yet, the songs of black-capped chickadees (Poecile atricapillus) show remarkable consistency across most of the species’ North American range. Previous research has described subtle variations in the song of this species by comparing songs...
