'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 drought, and other abiotic factors on tree water use in a temperate remnant forest
… examine daily, seasonal and annual patterns of water use by a native remnant woodland in temperate Australia. The focus of the study was on the two dominant tree species of the woodland, but limited assessments of understorey and soil evapotranspiration were also undertaken. One of dominant …

Branch, crown, tree and stand water flux in an 180-year-old loblolly pine plantation after thinning, fertilization, and throughfall exclusion treatments
Branch and tree sap flux density (SFD) was measured to evaluate the effects of thinning, fertilization, and throughfall exclusion treatments on water use by loblolly pine (Pinus taeda L.) trees. Variations in SFD at different radial xylem depths were also examined to improve estimates of tree water …

Canopy transpiration of beech forests in Northern Bavaria – Structure and function in pure and mixed stands with oak at colline and montane sites
Mixed stands of broadleaved deciduous tree species are increasing in importance in Bavaria and all of Germany, especially in the context of climate change, forest conversion and sustainable forestry. Very few investigations to date have quantified the canopy transpiration of mixed forest stands, …

Farmers’ Motivation and Biophysical Impact of using Cordia africana and Albizia coriaria on Coffee-Bean Intercrops in the Mt Elgon Region (Uganda)
… yields resulting from land degradation, land use pressures and unsustainable use of water resources. While deliberate integration of trees into farming systems (agroforestry) has been practiced traditionally in the Mt. Elgon region of Uganda since time immemorial, with modernisation of society …

Ecological-Hydrological Feedback in Forested Wetlands
… wetlands, the biotic and abiotic consequences of water level variability is not well understood. The effects of flooding on carbon and water exchanges are important knowledge gaps where progress could benefit management of natural resources and predicting of changes in surface geophysical cycles. …

The climatic significance of tropical forest edges and their representation in global climate models
… clearance of tropical humid forests influence water exchange between remnant forest patches and the atmosphere, and, if so, how this affects regional and global water exchange. Fieldwork presented in this thesis ascertains whether the amount of water transferred to the atmosphere from a humid …

Coordinated Tree Responses to Drought -Vulnerability and Sustainable Production: Hypotheses on Arid Ecosystem Adjustments to Limitations in Water Resources
Field and controlled greenhouse experiments were carried out to investigate tree responses to declining soil water content. Field experiments were conducted on naturally growing trees of Acacia tortilis and A. xanthophloea in the savanna region of Kenya and Quercus suber in the Mediterranean region …

Quantifying water use by temperate deciduous forests in South Korea : roles of species diversity, canopy structure, and complex terrain
… terrains not suitable for agriculture. Because mountains are important water sources for cities and human population downstream, performing water balance for forest catchments has become a research priority. The ongoing shift from coniferous to species-rich deciduous forests due to a …
