Climate-driven variations in productivity reveal adaptive strategies in Iberian cork oak agroforestry systems

Forest Ecosystems, Journal Year: 2022, Volume and Issue: 9, P. 100008 - 100008

Cork oak agroforestry systems (AFS) have been managed for centuries by humans to produce cork and other goods services recently recognised as an important reservoir biodiversity improvement conservation. However, despite having included a natural habitat of community-wide interest within the EU Habitats Directive, these are in critical situation decline. Among factors, they strongly threatened climate change, effects which also expected be particularly severe Mediterranean region.

The multidimensionality of plant drought stress: The relative importance of edaphic and atmospheric drought

Plant Cell & Environment, Journal Year: 2024, Volume and Issue: 47(9), P. 3528 - 3540

Published: June 28, 2024

Drought threatens plant growth and related ecosystem services. The emergence of drought stress under edaphic is well studied, whilst the importance atmospheric only recently gained momentum. Yet, little known about interaction relative contribution on stress. We conducted a gradient experiment, fully crossing gravimetric water content (GWC: maximum holding capacity-permanent wilting point) vapour pressure deficit (VPD: 1-2.25 kPa) using five wheat varieties from three species (Triticum monococcum, T. durum & aestivum). quantified occurrence molecular (abscisic acid), cellular (stomatal conductance), organ (leaf potential) stand level (evapotranspiration). Plant increased with decreasing GWC across all organizational levels. This effect was magnified nonlinearly by VPD after passing critical threshold soil availability. At around 20%GWC (soil matric potential 0.012 MPa), plants lost their ability to regulate leaf via stomata regulation, followed hydraulic dysfunction. characterized changing contributions versus atmosphere non-linear interaction. highly response likely abruptly alter plant-related services in drying world.

Exploring meteorological droughts' spatial patterns across Europe through complex network theory

Nonlinear processes in geophysics, Journal Year: 2023, Volume and Issue: 30(2), P. 167 - 181

Published: June 15, 2023

Abstract. In this paper we investigate the spatial patterns and features of meteorological droughts in Europe using concepts methods derived from complex network theory. Using event synchronization analysis, uncover robust drought continental networks based on co-occurrence these events at different locations within a season 1981 to 2020 compare results for four accumulation periods rainfall. Each is then further examined unveil regional clusters which are characterized terms droughts' geographical propagation source–sink systems. While introducing new methodologies general climate reconstruction raw data, our approach brings out key aspects concerning dynamics, could potentially support forecast.

A spatial framework for prioritizing biochar application to arable land: A case study for Sweden

Resources Conservation and Recycling, Journal Year: 2022, Volume and Issue: 189, P. 106769 - 106769

Published: Nov. 16, 2022

The biochar-agriculture nexus can potentially generate several benefits ranging from soil carbon sequestration to the reduction in nutrient leaching arable soils. However, leveraging these requires spatially-explicit information on suitable locations for biochar application. This study provides a flexible multicriteria framework that delivers spatial indications prioritization through use indication map (BUIM). was exemplified as case Swedish land three different narratives. BUIM all narratives revealed significant fraction of could benefit Furthermore, scored high given narrative did not necessarily score others, thus indicating application schemes be adjusted various objectives and local needs. presented here aims promote exploration avenues deploying agricultural sector.

The need to decipher plant drought stress along the soil–plant–atmosphere continuum

Oikos, Journal Year: 2023, Volume and Issue: 2023(9)

Published: July 11, 2023

Lacking comparability among rainfall manipulation studies is still a major limiting factor for generalizations in ecological climate change impact research. A common framework studying drought effects urgently needed to foster advances understanding the of drought. In this study, we argue, that soil–plant–atmosphere‐continuum (SPAC), describing flow water from soil through plant atmosphere, can serve as holistic concept experiments which allows reconciliation experimental ecology. Using data, show investigations leaf potential combination with edaphic and atmospheric – three main components SPAC are key understand effect on plants. Based systematic literature survey, especially based quantifications strongly underrepresented integrative assessments all almost absent current literature. our observations dynamics status different conducted ecosystems species facilitate extrapolation other systems, or future climates.
