Abstract:: ... Farmland birds have declined throughout Europe over recent decades. Many farmland songbirds are associated with linear woody features on field boundaries, such as hedgerows and tree lines. Previous studies have assessed songbird associations with specific hedgerow and tree characteristics, and their landscape context, but large-scale assessments have been limited by difficulties in mapping linear ...

Abstract:: ... There is growing interest in plantation forests throughout Africa because of their role in environment, economy and people's livelihoods. However, the contribution of planted forests to climate mitigation is poorly understood, partly due to lack of allometric equations for biomass estimation. This study aimed to determine wood density and biomass fractions in aboveground components, and to develop ...

Abstract:: ... Digital hemispherical photography (DHP) is widely used to measure the radiative environment and estimate sky view factors (SVF) in urban areas and leaf area index (LAI) in forests. However, a limitation is the difficulty to distinguish trees from buildings, or leaves from stems and branches. In this study, we collected and processed dual-wavelength photographs recording visible and near-infrared ( ...

Abstract:: ... Forest management planning is often challenged by the need to address contrasting preferences from several actors. Participatory approaches may help integrate actors’ preferences and demands and thus address this challenge. Workshops that encompass a participatory approach may further influence actors’ opinions and knowledge through social interaction and facilitate the development of collaborativ ...

Abstract:: ... Forests in South Africa are under threat from a variety of anthropogenic land use changes; however, the impacts of these changes on wildlife populations are poorly understood. To address this issue, a pan-European trait-based risk assessment framework was modified for use in South Africa. This framework allows the identification of habitats and species most at risk, as well as the most important t ...

Abstract:: ... In tropical dry forests, deciduousness (i.e., leaf shedding during the dry season) is an important adaptation of plants to cope with water limitation, which helps trees adjust to seasonal drought. Deciduousness is also a critical factor determining the timing and duration of carbon fixation rates, and affecting energy, water, and carbon balance. Therefore, quantifying deciduousness is vital to und ...

83. Evaluation of low-exergy heating and cooling systems and topology optimization for deep energy savings at the urban district level

Subject:: ambient temperature; cooling systems; density; energy conservation; energy conversion; heat; infrastructure; models; paper; planning; system optimization; thermal energy; topology; trees
Abstract:: ... District energy systems have the potential to achieve deep energy savings by leveraging the density and diversity of loads in urban districts. However, planning and adoption of district thermal energy systems is hindered by the analytical burden and high infrastructure costs. It is hypothesized that network topology optimization would enable wider adoption of advanced (ambient temperature) distric ...

Abstract:: ... Agricultural intensification causes habitat modification, sometimes leading to habitat loss and subsequent loss of connectivity. Remaining species in these agriculture-dominated landscapes often use hedgerows, such as windbreaks or riparian strips, as movement corridors or even as habitats. However, the understanding of the use of these hedgerows by mammals is limited and could be improved with th ...

Abstract:: ... Monitoring programs should be based on the measurement of two main pillars for evaluating the conservation status of a species: population size and geographical distribution. To date, the only way reported in the literature to obtain detailed information on L. cervus population size is to use the capture-mark-recapture method. This is an expensive and time-consuming technique that implies physical ...

The goal of this paper is to investigate whether variability in plant grow ...
