Mosasauridae is a lineage of extinct marine squamates that inhabited the world’s oceans during the Late Cretaceous (100-66 Ma). The name Mosasaurus was given to the first described specimen, which was a fossil discovered in Maastricht, the Netherlands, during the 1770s. Naturalists of the time...

Bare-bones Paleontology: An Examination of the Systematic Methods Used in Vertebrate Paleontology and their Congruence with Avian Ichnotaxonomy
DownloadSpring 2016
Data used in the systematic paleontology of extinct vertebrates is limited to what can be collected from detailed comparisons of preserved anatomy. This restricts vertebrate paleontologists to those characters preserved on osteological specimens. Furthermore, parataxonomies such as ichnotaxonomy...

Cranial Morphology, Taxonomy, and Systematics of Pachycephalosaurids (Dinosauria, Ornithischia)
DownloadSpring 2022
Pachycephalosauridae (pachcycephalosaurids) were small to medium sized bipedal ornithischians, known solely from the Late Cretaceous of North America and Asia. These dinosaurs are characterised by thick, often domed frontals and parietals (frontoparietal dome), which are thought to have been used...

Cyanogenic glycosides are secondary plant compounds that are widespread in the plant kingdom. Their biosynthesis starts with the conversion of aromatic or aliphatic amino acids into their respective aldoximes, catalysed by N-hydroxylating cytochrome P450 monooxygenases (CYP) of the CYP79 family....

Diversity among taxodiaceous conifers: Metasequoia foxii sp. nov. from the Paleocene of central Alberta, Canada.
Download2001
Falder, A.B., Stockey, R.A., Rothwell, G.W.
A single species of taxodioid conifers is among the dominant floristic elements at two stratigraphically contemporaneous Paleocene fossil localities in central Alberta, Canada. More than 10,000 compression specimens, including oppositely branched stems, vegetative shoots with decussately arranged...

S., Huber, Dezene P. W., Jones, Steven J. M., Keeling, Christopher I.
Background The mountain pine beetle, Dendroctonus ponderosae Hopkins, is the most serious insect pest of western North American pine forests. A recent outbreak destroyed more than 15 million hectares of pine forests, with major environmental effects on forest health, and economic effects on the...

Growth and Physiological Responses of Conifer Seedlings to Salt Stress and Nutrient Deficiency
DownloadSpring 2018
Oil sands extraction and refining can cause many negative environmental impacts and because these activities usually take place in the forest region, the Government of Alberta requires that, after mine sites are closed, the companies perform reclamation. The properties of reclaimed oil sands...

Speciation can be an elaborate process. Delimiting species and reconstructing evolutionary relationships may be similarly complex, revealing gene tree discordance, cryptic species, geographic structuring or hybridization. In order to solve such systematic problems, a careful balance should be...

Microascus brevicaulis sp. nov., the Teleomorph of Scopulariopsis brevicaulis, Supports Placement of Scopulariopsis with the Microascaceae
Download1998
Abbott, Sean P., Sigler, Lynne, Currah, R.S.
Five isolates of Scopulariopsis brevicaulis have been found to form perithecia in addition to typical conidia. The teleomorph is described as Microascus brevicaulis sp. nov., characterized by small (70-130 pLm diam), black, ostiolate ascocarps that are papillate or very short-necked, and with a...
