Are Point Counts of Boreal Songbirds Reliable Proxies for More Intensive Abundance Estimators?
Download2006
Villard, M.-A., Schmiegelow, F.K.A., Hannon, S.J., Toms, J.D.
Point counts are often used to provide information on abundance of songbirds. If data from point counts are to be compared in space or time, however, any bias in the estimate should be consistent and linearly related to the true abundance. Several studies have suggested that this assumption may...

Are the “ seeds ” of spatial variation in cyclic dynamics apparent in spatially-replicated short time-series ? An example from the forest tent caterpillar
Download2005
Variation in the pattern of dynamics of the forest tent caterpillar was assessed over a 13-year interval of population collapse and increase among 68 sites within a 420 km2 region. Patterns of population change were compared with the level of forest fragmentation among sites, and interpreted in...

Underpinning the International Union for Conservation of Nature (IUCN) Red List is the assessment of extinction risk as determined by the size and degree of loss of populations. The IUCN system lists a species as Critically Endangered, Endangered, or Vulnerable if its population size declines...

Aroid Seeds from the Middle Eocene Princeton Chert ( Keratosperma allenbyense , Araceae): Comparisons with Extant Lasioideae.
Download2003
A reinvestigation of more than 200 new specimens of Keratosperma allenbyense Cevallos-Ferriz et Stockey from the Middle Eocene Princeton chert allows a more detailed comparison with living Araceae and provides evidence for the evolution of the lasioid clade. The anacampylotropous seeds possess a...

Arrays of TiO2 nanorods embedded with fluorine doped carbon nitride quantum dots (CNFQDs) for visible light driven water splitting
Download2018-04-03
P Kumar, UK Thakur, K Alam, P Kar, R Kisslinger, S Zeng, S Patel, K Shankar
Graphenic semiconductors such as carbon nitride are attracting increasing attention as photocatalysts due to their chemical stability, visible light absorption and excellent electronic properties. The photocatalytic activity of nanostructured TiO2 catalysts is constrained by the wide bandgap and...

Arterial retention of remnant lipoproteins ex-vivo is increased during insulin resistance due to increased arterial biglycan and production of cholesterol-rich atherogenic particles, that can be improved by ezetimibe in the JCR:LA-cp rat
Download2012
Russell, James C., Proctor, Spencer D., Uwiera, Richard R. E., Vine, Donna F., Mangat, Rabban, Hassanali, Zahra, Cheeseman, Christopher I., Borthwick, Faye, Warnakula, Samantha
Background Literature supports the “response-to-retention” hypothesis—that during insulin resistance, impaired metabolism of remnant lipoproteins can contribute to accelerated cardiovascular disease progression. We used the JCR:LA-cp rat model of metabolic syndrome (MetS) to determine the extent...

Arthritis in the Canadian Aboriginal population: north-south differences in prevalence and correlates
Download2010
Ng, Carmina, Chatwood, Susan, Young, T. Kue
"Background: Information on arthritis and other musculoskeletal disorders among Aboriginal people is sparse. Survey data show that arthritis and rheumatism are among the most commonly reported chronic conditions and their prevalence is higher than among non-Aboriginal people. Objective: To...

Mackey discusses the impact of television on young viewers by tracing Arthur the Aardvark's transformation--and influence on children--from a literary creation to the popular hero of a daily TV show and a Web page to an ActiMate doll.

The purpose of this paper is to propose a taxonomy of artificial intelligence (AI) literacy to support AI literacy education and research. This study makes use of the facet analysis technique and draws upon various sources of data and information to develop a taxonomy of AI literacy. The research...

Greif, M.D., Tsuneda, A., Currah, R.S., Gibas, C.F.C.
Catinella olivacea is a discomycetous fungus often found fruiting within cavities in rotting logs. Because this habitat would lack the air currents upon which discomycete species normally rely for the dispersal of their forcibly ejected ascospores, we suspected an alternative disseminative...
