Source-receptor relationships for speciated atmospheric mercury at the remote Experimental Lakes Area, northwestern Ontario, Canada
Download2012
Zhang, L., Blanchard, P., Cheng, I., Graydon, J.A., St. Louis, V.L.
Source-receptor relationships for speciated atmospheric mercury measured at the Experimental Lakes Area (ELA), Northwestern Ontario, Canada were investigated using various receptor-based approaches. The data used in this study include gaseous elemental mercury (GEM), mercury bound to fine...

Spatial genetic structure of a symbiotic beetle-fungal system: Toward multi-taxa integrated landscape genetics
Download2011-01-01
Sperling, Felix A. H., Hamelin, Richard C., Murray, Brent W., James, Patrick M. A., Coltman, Dave W.
Spatial patterns of genetic variation in interacting species can identify shared features that are important to gene flow and can elucidate co-evolutionary relationships. We assessed concordance in spatial genetic variation between the mountain pine beetle (Dendroctonus ponderosae) and one of its...

Spatial heterogeneity in trophic status of shallow lakes on the Boreal Plain: Influence of hydrologic setting
Download2008
Creed, I.F., Sass, G.Z., Devito, K.J.
[1] We used metrics of surface water and groundwater connectivity as explanatory variables in nonparametric regression models to explain the spatial heterogeneity in trophic status of shallow lakes. The concentration of chlorophyll a (Chl a) was used as an indicator of trophic status and was...

Memory is critical to understanding animal movement but has proven challenging to study. Advances in animal tracking technology, theoretical movement models and cognitive sciences have facilitated research in each of these fields, but also created a need for synthetic examination of the linkages...

Mathematical models of spatial population dynamics typically focus on the interplay between dispersal events and birth/death processes. However, for many animal communities, significant arrangement in space can occur on shorter timescales, where births and deaths are negligible. This phenomenon...

McCauley, E., Lewis, M. A., Lutscher, F.
River ecosystems are the prime example of environments where unidirectional flow influences the dispersal of individuals. Spatial patterns of community composition and species replacement emerge from complex interplays of hydrological, geochemical, biological, and ecological factors. Local...

Mercer, G., St. Clair, C. C., Whittington, J.
Increasing levels of human activity in mountainous areas have high potential to inhibit animal movement across and among valleys. We examined how wolves respond to roads, trails, and other developments. We recorded the movements of two wolf packs for two winters by following their tracks in the...

Spatial scales of habitat selection decisions: implications for telemetry-based movement modeling
Download2017-04-01
Guillaume Bastille-Rousseau, Dennis L. Murray, James A. Schaefer, Mark A. Lewis, Shane P. Mahoney, Jonathan R. Potts
Movement influences a myriad of ecological processes operating at multiple spatial and temporal scales. Yet our understanding of animal movement is limited by the resolution of data that can be obtained from individuals. Traditional approaches implicitly assume that movement decisions are made at...
