Migration and survival of Parnassius smintheus: Detecting effects of habitat for individual butterflies
Download2004
Hanski, I., Roland, J., Matter, S. F., Moilanen, A.
We examined the migration and survival of the butterfly Parnassius smintheus in a heterogeneous landscape consisting of 21 habitat patches imbedded in a matrix of meadow and forest habitat. We modified an existing mark-release-recapture model to account for multiple habitat types and fit the...

Mitochondrial DNA variation and identification of bark weevils in the Pissodes strobi species group in western Canada (Coleoptera: Curculionidae)
Download1995
Sperling, F. A. H., Langor, D. W.
Abstract: Morphological, allozyme, and chromosomal characters and ecological traits have limited value for discriminating among four closely related Pissodes spp. known from western Canada. We amplified a 1585-bp segment of mitochondrial DNA (mtDNA), including half of the cytochrome oxidase I...

Molecular Mechanisms Underlying the Enhancement of Cardiac Contraction by Modifications of Troponin
DownloadFall 2015
A fine balance between contraction and relaxation is crucial for the heart to function properly. But often the heart cannot contract with enough force to meet the demands of the body. This condition, called systolic heart failure, is the leading cause of death in the modern society. A common...

Multinuclear Magnetic Resonance Tracking of Hydro, Thermal and Hydrothermal Decomposition of CH3NH3PbI3
Download2017-01-01
Askar, A.,, Bernard, G.M, Wiltshire,, B., Shankar, K., Michaelis, V.K.
An NMR investigation of methylammonium lead iodide, the leading member of the hybrid organic-inorganic perovskite class of materials, and of its putative decomposition products as a result of exposure to heat and humidity, has been undertaken. We show that the 207Pb NMR spectra of the compound of...

New insights about barnacle reproduction: Spermcast mating, aerial copulation and population genetic consequences
DownloadSpring 2014
Barnacles are mostly hermaphroditic and they are believed to mate via copulation or, in a few species, by self-fertilization. However, isolated individuals of two species that are thought not to self-fertilize, Pollicipes polymerus and Balanus glandula, nonetheless carried fertilized...

Fall 2017
Photoreceptors (the light-sensitive cellular mediators of vision in the eye) are divided into two classes: rods, which are sensitive to dim light and responsible for vision in low-light conditions, and cones, which are sensitive to specific wavelengths of light, and are responsible for daytime...

Spring 2016
Polar bears (Ursus maritimus) were among the first large mammals to be assessed for genetic variation in the wild, and they remain a common subject of genetics studies. Although recent advances in genotyping technology have allowed for more accurate determination of population structure and the...

Population Structure of Mountain Pine Beetle Symbiont Leptographium longiclavatum and the Implication on the Multipartite Beetle-Fungi Relationships
Download2014-01-01
Roe, Amanda D., Farfan, Lina, Cooke, Janice E. K., Hamelin, Richard C., El-Kassaby, Yousry A., Rice, Adrianne V., Tsui, Clement K.
Over 18 million ha of forests have been destroyed in the past decade in Canada by the mountain pine beetle (MPB) and its fungal symbionts. Understanding their population dynamics is critical to improving modeling of beetle epidemics and providing potential clues to predict population expansion....
