Download or read book Environmental Site Conditions and Habitat Characteristics Influence Biocontrol Insects of Yellow Starthistle Centaurea Solstitialis in Washington USA written by Steven Edward Woodley and published by . This book was released on 2018 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is comprised of three separate field studies which took place in eastern Washington State and occurred between 2014 through 2017. The first, a 2-year (2014-2015) field study quantified the effect of environmental factors on the overwintered Eustenopus villosus (Boheman) and Larinus curtus (Hochhut) adults in relation to the phenology of Centaurea solstitialis L. (Asteraceae: Cardueae). Results suggested that the appearance and increase in frequency of the overwintered E. villosus and L. curtus adults was likely a function of warming temperatures. Both species' decline in frequency was likely a function of the weevils completing their life cycle in synchrony with the phenological advancement of C. solstitialis and decline of abundant breeding and foraging sites (buds and flowers). The second 2-year field study (2014-2015) examined percent infestation of E. villosus and L. curtus and the species percent seed consumption in Washington compared to studies in California and Greece to determine if differences in macroclimates influence the efficacy of the species. Findings suggested that differences in macroclimates does not appear to influence either species percent infestation or seed consumption. The third, a one-year field study (2017) examined the influence of physical environmental conditions and habitat characteristics on the composition of colonization by biocontrol insects of C. solstitialis biocontrol insects. In addition, this research examined whether different colonization by C. solstitialis biocontrol insects at a site created differences in the percent of C. solstitialis flowerheads infested and seed consumption in the southeastern corner of Washington. Results indicate that different environmental conditions and habitat characteristics which create the effective environment for the insects and reflected by the different plant associations and C. solstitialis seed production between sites, influence the composition of colonization by C. solstitialis biocontrol insects. Different effective environments create opportunity for physiological selection by biological insects of C. solstitialis . In addition, consumptive competition, seasonal emergence, and/or the timing of ovipositing by the overwintering generations may also play a significant role in the composition of colonization. Sequentially, differences in the composition of colonization create differences in the efficacy of control C. solstitialis by biocontrol insects.

Download or read book Field Guide for the Identification of Invasive Plants in Southern Forests written by James H. Miller and published by DIANE Publishing. This book was released on 2011-08 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasions of non-native plants into forests of the Southern United States continue to go unchecked and only partially un-monitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called non-native, exotic, non-indigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This guide provides information on accurate identification of the 56 non-native plants and groups that are currently invading the forests of the 13 Southern States. In additin, it lists other non-native plants of growing concern. Illustrations. This is a print on demand edition of an important, hard-to-find publication.

This book was released on 2012-12-06 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mediterranean-type ecosystems have provided ecologists with some of the most scientifically-rewarding opportunities to formulate and evaluate hypotheses about large and small-scale ecological phenomena. Comparison of mediterranean-type climate ecosystems in different parts of the world has not only permitted a strong test for ecological convergence, but also critical understanding of key ecophysiological and population processes.

Book excerpt: Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination differs from all other books on seed germination. It is an all-encompassing volume that provides a working hypothesis of the ecological and environmental conditions under which various kinds of seed dormancy have developed. It also presents information on the seed germination of more than 3500 species of trees, shrubs, vines and herbaceous species, making this a valuable reference for anyone studying germination. This book delivers information on characteristics of each type of seed dormancy, how each type of dormancy is broken in nature, and what environmental conditions are required for germination after dormancy is broken. It explains how studies should be done to distinguish persistent from transient seed banks, and covers which species should be controlled, propagated, and conserved. Seeds gives the reader insight and guidelines for doing ecologically meaningful studies on the biogeography and evolution of seed dormancy and germination in order to better understand plant reproductive strategies, life history traits, adaptations to habitats, and physiological processes. Evolutionary/phylogenetic origins and relationships of various kinds of seed dormancy A world biogeographical perspective on seed dormancy and germination Ecophysiology of seeds with each type of dormancy Critical evaluation of methodology used in soil seed bank studies Germination ecology of plants with specialized habitat and life cycle types Genetic and maternal preconditioning effects on seed dormancy and germination Guidelines for doing ecologically-meaningful germination studies
