Le site constitue un outil dynamique de détermination des végétaux en ligne, basé sur la manipulation de photos, schémas, glossaire interactif et clés dichotomiques. Le site est accessible à l’adresse: www.biologievegetale.be.
La plate-forme, initialement conçue pour faciliter l’apprentissage des étudiants, constitue également un outil pour le gestionnaire de sites ou le naturaliste. Elle permet d’identifier une espèce végétale à l’aide de clés dichotomiques interactives. Connaître les espèces rencontrées s’avère être la base indispensable pour toute tâche d’évaluation de la structure ou de la qualité d’une végétation. La plate-forme comporte (i) des exercices permettant de s’exercer à la détermination des végétaux. Des liens hypertextes expliquent et illustrent les termes de vocabulaire particuliers. (ii) Une flore en ligne comprenant de nombreuses fiches espèces (descriptions et illustrations), dont par exemple l’ensemble des arbres et arbustes indigènes ou plantés. (iii) Une auto-évaluation des connaissances avec exercices et quizz.

This open textbook is intended to expose students to the application of quantitative genetic models to plant breeding populations. Specific topics include conducting and interpreting multi-environment trials, resource allocation using engineering principles, genetic modeling of quantitative traits, simulation modeling, variance, covariance and heritability, prediction, selection, and genetic gain.

We use eigenvector-eigenvalue analysis to walk through a simple quasispecies model described in Bull, Meyers, and Lachmann, "Quasispecies made simple," PLoS Comp Biol, 1(6):e61 (2005). The dominance of a genotype depends, not merely on its ability to breed quickly (i.e. the rudimentary concept of survival of the fittest), but also on its ability to breed "true."

Proper management of uneven-aged interior Douglas-fir (Pseudotsuga menziesii var. glauca) stands is important for British Columbia’s central and southern interior. These stands constitute one of main components of the operable forest land in these areas, with easy access from main roads and towns. This study focused on the growth of uneven-aged Douglas-fir stands after pre-commercial thinning (spacing), with an impetus to improve upon current management practices. Data were collected from 24 permanent sample plots which were established near Williams Lake, British Columbia in 1989; thinning took place between 1990 and 1991. Three measurements have been made post-treatment: 1993, 1997 and 2004. The plot data were used to analyze different growth responses among three different spacing regimes (standard, 3 m clumped and 5 m clumped spacing) and a control. Analyses were performed at both the stand and tree level. The growth of basal area per ha, quadratic mean dbh, volume per ha and Lorey’s height were used for stand level analyses. At the tree level, dbh, height, basal area and volume were the variables of interest. At the stand level, mortality increased (7.1 to 107.1 stems/ha) and ingrowth decreased (2.4 to 8.6 stems/ha) for the second growth period (1997-2003), compared to the first growth period (5.8 to 107.1 stems/ha and 5.0 to 12.4 stems/ha, respectively). No significant differences in annual growth of quadratic mean dbh, basal area and volume per ha and Lorey’s height were noted between the different spacing regimes and the control. At the individual tree level, the 5 m clumped spacing regime usually had the highest dbh, basal area and volume growth for both growth periods. The one exception was for height growth, when analyzed using mixed-effects modeling, where no significant differences were found. Trees on the other two spacing regimes also had higher growth in dbh, basal area, and volume than trees on the control plots. The positive growth response to the spacing treatments at the single tree level was obtained without a reduction in growth at the stand level. This growth increase will result in the residual trees reaching larger sizes more quickly than they would have with no treatment, leading to improved mule deer winter range habitat and higher timber values.

Cretaceous and Tertiary strata exposed in northern Alaska record clastic sediment deposition within a foreland basin adjacent to the ancestral Brooks Range, and form part of an important petroleum play. The goal of this U.S. Geological Survey report is to synthesize the complex stratigraphy of this area into a more simplified scheme. It discusses the regional geology of northern Alaska and the stratigraphy of the Colville Basin in detail. Maps, cross sections, correlation charts, and numerous outcrop photos with detailed captions accompany the text.

Soil and Water Conservation: An Annotated Bibliography highlights freely-available online resources covering various aspects of soil and water conservation, and is designed to be a resource for conservation students and practitioners. The thirteen chapters in the annotated bibliography are grouped into four sections, including History and Fundamentals, Conservation Practices, Conservation Implementation, and Careers. Types of cited resources include extension bulletins, USDA NRCS conservation practice standards, and other government reports and resources. Cited resources are generally concise, easily read, and meant for general audiences. Annotations and images are used to provide context for each resource. Many contributors made Soil and Water Conservation: An Annotated Bibliography possible through their assistance with technical edits, outline development, identifying resources, or writing annotations. Chapter authors are experts and practitioners of soil and water conservation, or students of soil and water conservation who worked under the supervision of the editor, Colby Moorberg. The annotated bibliography is used as the primary text for Kansas State University’s AGRON 635 – Soil and Water Conservation, which is taught by Moorberg.
