Impacts of air pollution on human and ecosystem health, and implications for the National Emission Ceilings Directive. Insights from Italy [PDF]

, 2019
Across the 28 EU member states there were nearly half a million premature deaths in 2015 as a result of exposure to PM2.5, O3 and NO2. To set the target for air quality levels and avoid negative impacts for human and ecosystems health, the National ...

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Some aspects of the competition between seedlings of gorse (Ulex europaeus L.) and "Grasslands Nui" perennial ryegrass (Lolium perenne L.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science at Massey University [PDF]

, 1978
Two glasshouse trials were conducted with "Grasslands Nui" perennial ryegrass (Lolium perenne L.) and gorse (Ulex europaeus L.) grown in boxes separately as monocultures and as mixtures forming a replacement series.

Legacies from early‐season hot drought: how growth cessation alters tree water dynamics and modifies stress responses in Scots pine

Plant Biology, EarlyView.
Early‐season hot drought in Scots pine limits growth and productivity but improves resilience to late‐season drought through reduced water use. Abstract Tree responses to drought are well studied, but the interacting effects of drought timing on growth, water use, and stress legacy are less understood.

Defoliation of the vines before or after berry set: Physiological consequences and qualitative factors

IVES Technical Reviews, 2019
Defoliation of the vines consists of eliminating the leaves in the grape bunch zone in a more or less intensive manner. It is a long-proven prophylactic technique that has seen a renewed interest in the current context of the reduction of phytosanitary ...

Dual Polarimetric Radar Vegetation Index for monitoring forest moisture stress using time series of Sentinel‐1 SAR data

Plant Biology, EarlyView.
This study demonstrates the potential of the Sentinel‐1 Dual Polarimetric Radar Vegetation Index, combined with climate variables and the Standardized Precipitation–Evapotranspiration Index, to effectively detect and monitor drought‐induced stress in temperate broadleaf deciduous forests.

Lotus tenuis in Association with Arbuscular Mycorrhizal Fungi Is More Tolerant to Partial Submergence than to High-Intensity Defoliation

International Journal of Plant Biology
This study aimed to investigate the effect of the association of Lotus tenuis with arbuscular mycorrhizal fungi (AMF) on its development under high defoliation intensity or partial submergence in a P-deficient soil of the Salado River Basin in a pot ...
