Ammar Hassanzadeh Keshteli, Dana Allen, Afia Anjum, Yashvi Patel, Aadhavya Sivakumaran, Siyang Tian, Fei Wang, Hao Wang, Mark A. Lewis, Russell Greiner, David S. Wishart
One year after identifying the first case of the 2019 coronavirus disease (COVID-19) in Canada, federal and provincial governments are still struggling to manage the pandemic. Provincial governments across Canada have experimented with widely varying policies in order to limit the burden of...

A Mark-Recapture Study of Trematode Parasitism in Overwintered Helisoma anceps (Pulmonata), with Special Reference to Halipegus occidualis (Hemiuridae).
Download1989
Shostak, A.W., Esch, G.W., Goater, T.M., Williams, J.A.
A collection of 556 snails, Helisoma anceps, was made from a pond in the Piedmont area of North Carolina during October 1987. Snails were measured and assayed for trematode parasitism, and then 500 randomly selected individuals were marked and returned to the pond. Collections made between 23...

Territorial behaviour is widespread in the animal kingdom, with creatures seeking to gain parts of space for their exclusive use. It arises through a complicated interplay of many different behavioural features. Extracting and quantifying the processes that give rise to territorial patterns...

A mechanistic model for understanding invasions: using the environment as a predictor of population success
Download2011-01-01
DiBacco, C., Lewis, Mark A., Strasser, C. A.
Aim We set out to develop a temperature-and salinity-dependent mechanistic population model for copepods that can be used to understand the role of environmental parameters in population growth or decline. Models are an important tool for understanding the dynamics of invasive species; our model...

A microsatellite polymorphism in the gamma interferon gene is associated with resistance to gastrointestinal nematodes in a naturally-parasitized population of Soay sheep

Pemberton, J. M., Coltman, D. W., Pilkington, J. G., Wilson, K., Stear, M. J.
Abstract: Free-living Soay sheep (Ovis aries) on the island of Hirta, St Kilda, Scotland, are naturally parasitized bq gastrointestinal nematodes, predominantly Teladorsagia circumcincta. In this paper we show that reduced faecal egg counts (FEC) are associated with an allele at a microsatellite...

Mathematical models have been widely applied to perform chemical risk assessments on biological populations for a variety of ecotoxicological pro- cesses. In this paper, by introducing a dose-dependent mortality rate function, we formulate a toxin-dependent aquatic population model that...

A Modeling Framework for Assessing the Potential Impacts of Climate Change in Northeastern Alberta
Download2008-12-19
This paper provides a framework for modeling the effects of climate change on key indicators of interest to regional land-use planning teams. The framework is based on input from a technical workshop held on October 16, 2008, as well as follow-up with technical experts and a review of the...

A Morphological Investigation of the Unusual Cryptogeal Germination Strategy of Bunya Pine (Araucaria bidwillii)-An Australian Rain Forest Conifer.
Download1992
Burrows, G.E., Stockey, R.A., Boag, T.S.
The morphology of the cryptogeal germination sequence of Araucaria bidwillii (bunya pine) was studied. Individual seeds were 5-6 cm in length and 2.5-3.5 cm in diameter and had an average fresh weight of ca. 16 g. In mature seeds the embryo consisted of a cotyledon tube, hypocotyl, and root cap...

A multi-scale test of the forage maturation hypothesis in a partially migratory ungulate population
Download2008
McDermid, G., Hebblewhite, M., Merrill, E.
The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate forage biomass to maximize energy intake...
