Resource allocation, water relations and crown architecture examined at the tree and stand-level in northern conifers
DownloadFall 2013
Variation in quantity of light has driven plants to employ many strategies in order to persist in high and low light. It is also a primary driver of lower branch mortality and crown recession. Fine roots and leaves are complimentary tissues representing belowground and aboveground resource...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...

Roger Saylor and Michel Ferrari (eds): Epistemology and Science Education: Understanding the Evolution vsntelligent Design Controversy
Download2012
Introduction: For decades the creationist movement has threatened the teaching of evolution in the United States, even in public schools. Similar worrisome trends have started in other Western countries. Beyond the major importance of reacting to attempts to undermine the proper teaching of...

Seasonal photosynthetic activity in evergreen conifer leaves monitored with spectral reflectance
DownloadSpring 2014
Annual trends of the Photochemical Reflectance Index (PRI) and pigment content in evergreen conifer leaves were monitored over two years from 2011 to 2013. During the second year, chlorophyll fluorescence and gas exchange were included to examine the spring recovery of photosynthesis. All the...

Speirseopteris orbiculata gen. et sp. nov. (Thelypteridaceae), a derived fossil filicalean from the Paleocene of western North America.
Download2006
Stockey, R.A., Rothwell, G.W., Lantz, T.C.
An apparently exindusiate filicalean fern with radial sori, sporangia with a vertical annulus, and monolete spores occurs in Paleocene sediments ca. 57 million years old of central Alberta, Canada. Specimens are preserved as coalified compressions and show features of frond morphology and...

Stramineopteris aureopilosus gen. et sp. nov.: Reevaluating the Role of Vegetative Anatomy in the Resolution of Leptosporangiate Fern Phylogeny.
Download2006
Little, S. A., Stockey, R. A., Rothwell, G. W.
The discovery of two anatomically preserved rhizomes with attached stipe bases and adventitious roots contributes to our knowledge of filicalean fern diversity and evolution. Specimens are preserved in marine carbonate nodules at the Lower Cretaceous (Valanginian to Hauterivian) Apple Bay...

Stratigraphy, paleogeography and tectonic evolution of early Paleozoic to Triassic pericratonic strata in the northern Kootenay Arc, southeastern Canadian Cordillera, British Columbia
DownloadSpring 2013
The northern Kootenay Arc in southeastern British Columbia hosts a near-continuous succession of Cambrian to Permian strata that were deposited in overlapping marginal basins outboard of the Canadian Cordilleran miogeocline. The basinal strata of the Late Cambrian and younger Lardeau Group are...

Subfossil bryophytes in eastern Beringia: their paleoenvironmental and phytogeographical significance
Download1981
Doctoral thesis. Bryophytes, more particularly mosses, are used in the paleoenvironmental reconstruction and historical biogeography of eastern Beringia, an area including Alaska and the Yukon. The Old Crow Basin in northern Yukon was studied in detail. // Appendix 2: Subfossil bryophytes...
