Building A Mechanistic Understanding Of Biodiversity And Ecosystem Functioning In Forests
… being uncovered. I sought to understand how tree diversity could influence local resource pools of light, water, and nutrients, thereby affecting the growth, stress, and mortality of trees living in the area. I studied trees in a forest biodiversity experiment at different spatial and …

Dealing with contaminated land in the ‘New Regime’: an appraisal of the use of plants as biomonitors for metal contamination analysis and risk assessment for a former landfill site in Greenwich
… become available to the surrounding biota. Trees and plants growing in the vicinity of a contaminated site may provide such a historic record. There have been few studies on their role as biomarkers to identify metal mobility or bioavailability for continuous monitoring purposes. The aim of …

HOW TO REDUCE TRANSPLANT STRESS IN URBAN TREES
… and public services are promoting large scale tree planting programs in urban environment. However, these programs frequently experience very high rates of planting failure within the first years after planting and slow establishment, jeopardizing their ecological and socioeconomic benefits. …

Seasonal effects of elevated carbon dioxide, competition, and water stress on gas exchange and growth of loblolly pine and sweetgum grown in open-top chambers
Loblolly pIne (Pinus taeda) and sweetgum (Liquidambar styraciflua) were grown in miniature stands at 7.6-cm spacings outdoors in open-top chambers (4.6 m in diameter and 3.5 m tall) for 16 months. Treatments consisted of ambient- and elevated-CO₂ , drought-stressed and well-watered, and stand type …

Longterm Approaches to Assessing Tree Community Responses to Resource Limitation and Climate Variation
… change on forest dynamics will be determined by tree responses at different life-stages and different scales -- from establishment to maturity and from individuals to populations. Studies incorporating local factors, such as natural enemies, competition, or tree physiology, with sufficient …

'Hass' avocado tree water use and the effects of water stress on fruit development
‘Hass’ avocado tree water use and the effects of water deficits on fruit development were assessed in New Zealand from 2017 to 2019. Avocado tree water use was quantified by sap flow measurement and the soil water balance method at three sites in the main avocado growing regions of the Bay of …

The Influence of Chilling and Heat Accumulation on Bloom Timing, Bloom Length and Crop Yield in Almonds (Prunus dulcis (Mill.))
<p>Almonds are one of the first commercial nut trees to bloom in early spring and thus are susceptible to temperature patterns prior to and during bloom which affect bloom timing, bloom length, pollination and nut set. Data used in this project include yearly dates of 90% bloom from 1996-2006, …

Trockenheitsreaktionen und holzanatomische Eigenschaften der Zitter-Pappel (Populus tremula L.) – Physiologie und QTL-Mapping
Holz aus Kurzumtriebsplantagen (KUP) mit Pappeln (Populus spp.) kann eine bedeutende Rolle im Mix der Bioenergieressourcen in Deutschland spielen. Trotz eines günstigen Energieinput-Energieoutput-Verhältnisses ist das Erreichen wirtschaftlich zufriedenstellender Ergebnisse mit KUP jedoch auf den …
