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...

Despite the considerable attention given to morphology instruction in recent years, there remains an essential need to understand how and when it should be taught, as well as whether it is better suited for students with specific characteristics. Thus, the objective of this dissertation was...

Flowering plants have evolved a stunning array of floral colours, scents, and structures, which act synchronously as cues for pollinators. Comprehensive investigations of the extraordinarily diverse floral features involved in plant-pollinator interactions requires expansion of the comparative...

Roots of Typha latifolia L. exposed to Fe2+ under reduced conditions in solution culture developed visible coatings (plaques) of an oxidized Fe compound that extended as much as 15-17 ,um into the rhizosphere. Iron concentrations were significantly less and discoloration was not apparent on the...

Populations of a host species may exhibit different assemblages of parasites and other symbionts. The loss of certain species of symbionts (lineage sorting, or ‘‘missing-the-boat’’) is a mechanism by which geographical variation in symbiont assemblages can arise. We studied feather mites and lice...

Abstract: Species of Dioryctria Zeller (Lepidoptera: Pyralidae) are important pests of conifers, particularly in seed orchards, and accurate species identification is needed for effective monitoring and control. Variable forewing morphology and lack of species-specific genitalic features hinder...
