This book was released on 2009-03-05 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses advanced statistical methods that can be used to analyse ecological data. Most environmental collected data are measured repeatedly over time, or space and this requires the use of GLMM or GAMM methods. The book starts by revising regression, additive modelling, GAM and GLM, and then discusses dealing with spatial or temporal dependencies and nested data.

Download or read book Plant Competition in a Changing World written by Judy Simon and published by Frontiers Media SA. This book was released on 2017-06-22 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Competitiveness describes a key ability important for plants to grow and survive abiotic and biotic stresses. Under optimal, but particularly under non-optimal conditions, plants compete for resources including nutrients, light, water, space, pollinators and other. Competition occurs above- and belowground. In resource-poor habitats, competition is generally considered to be more pronounced than in resource-rich habitats. Although competition occurs between different players within an ecosystem such as between plants and soil microorganisms, our topic focusses on plant-plant interactions and includes inter-specific competition between different species of similar and different life forms and intra-specific competition. Strategies for securing resources via spatial or temporal separation and different resource needs generally reduce competition. Increasingly important is the effect of invasive plants and subsequent decline in biodiversity and ecosystem function. Current knowledge and future climate predictions suggest that in some situations competition will be intensified with occurrence of increased abiotic (e.g. water and nutrient limitations) and biotic stresses (e.g. mass outbreak of insects), but competition might also decrease in situations where plant productivity and survival declines (e.g. habitats with degraded soils). Changing interactions, climate change and biological invasions place new challenges on ecosystems. Understanding processes and mechanisms that underlie the interactions between plants and environmental factors will aid predictions and intervention. There is much need to develop strategies to secure ecosystem services via primary productivity and to prevent the continued loss of biodiversity. This Research Topic provides an up-to-date account of knowledge on plant-plant interactions with a focus on identifying the mechanisms underpinning competitive ability. The Research Topic aims to showcase knowledge that links ecological relevance with physiological processes to better understanding plant and ecosystem function.

Download or read book Competing Vegetation in Ponderosa Pine Plantations written by Philip M. McDonald and published by . This book was released on 1989 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planted ponderosa pine (Pinus ponderosa Dougl. ex Laws. var. ponderosa) seedlings in young plantations in California are at a disadvantage compared with competing shrubs, forbs, and grasses. In many instances, roots of competing plants begin expanding and exploiting the soil earlier and in greater numbers, thereby capturing the majority of available resources and lowering pine survival and growth. Competition thresholds or "how much is too much?" are: for treatments where a cleared radius is prescribed, no weeds are acceptable within the space needed for maximum growth of pine seedlings during the establishment period; for treatments involving the entire area, crown cover values of 10 to 30 percent seem to be the level beyond which shrub competition significantly affects pine growth. Methods for preparing the site, which include mechanical and chemical methods, use of fire, and combinations of treatments, show the interaction of site and ensuing vegetation. Techniques for controlling competing vegetation from seed include preventing such plants from getting started by use of preemergent herbicides or mats (collars). To prevent sprouting, hardwood trees and large shrubs can be pushed over, thereby getting the root crown out of the ground, or if still in the soil, grinding it out with a machine. Once present, the effect of weeds from seed can be minimized by grubbing or spraying when young, by grazing plants with cattle or sheep, or by introducing plants of low competitive ability. Once sprouting weeds are present, their effect can be minimized by spraying with chemicals, or if palatable, by grazing with cattle or sheep. Costs range from as low as $10 per acre ($25/ha) for aerially applying herbicides to $711 per acre ($1757/ha) for grinding out tanoak stumps.
