There Is No Carbon Transfer Between Scots Pine and Pine Mistletoe but the Assimilation Capacity of the Hemiparasite Is Constrained by Host Water Use Under Dry Conditions

Frontiers in Plant Science, 2022
Pine mistletoe is a hemiparasitic shrub that can produce its own photosynthates. There is a lack of knowledge about the interaction of mistletoe and host under varying environmental condition that might influence carbon gain and allocation.

Les forêts face aux sécheresses et canicules : causes de dépérissements, facteurs aggravants et différences de sensibilité entre les espèces

Revue Forestière Française, 2023
Des sécheresses impactant fortement les forêts se sont déjà produites dans le passé en Europe (1911, à la fin des années 1940, 1976). Les plus récentes des étés 2003, 2018 et 2022, ont été marquées également par des vagues de chaleur sans précédent.

Spaceborne LiDAR for characterizing forest structure across scales in the European Alps

Remote Sensing in Ecology and Conservation, 2023
The launch of NASA's Global Ecosystem Dynamics Investigation (GEDI) mission in 2018 opens new opportunities to quantitatively describe forest ecosystems across large scales. While GEDI's height‐related metrics have already been extensively evaluated, the

Effects of a regenerating matrix on the survival of birds in tropical forest fragments

Avian Research, 2020
Background Vast areas of lowland neotropical forest have regenerated after initially being cleared for agricultural purposes. The ecological value of regenerating second growth to forest-dwelling birds may largely depend on the age of the forest ...

Quantitative wood anatomy and stable carbon isotopes indicate pronounced drought exposure of Scots pine when growing at the forest edge

Frontiers in Forests and Global Change, 2023
Climate change poses a major threat to global forest ecosystems. In particular, rising temperatures and prolonged drought spells have led to increased rates of forest decline and dieback in recent decades.

Sugar infusion into trees: A novel method to study tree carbon relations and its regulations

Frontiers in Plant Science, 2023
Many carbon-related physiological questions in plants such as carbon (C) limitation or starvation have not yet been resolved thoroughly due to the lack of suitable experimental methodology.

Decline in commercial pine nut and kernel yield in Mediterranean stone pine (Pinus pinea L.) in Spain

iForest - Biogeosciences and Forestry, 2020
Cones of the Mediterranean stone pine (Pinus pinea L.) constitute one of the most relevant non-wood forest products collected in the Mediterranean forests, providing high value edible kernels.

Stand-level biomass models for predicting C stock for the main Spanish pine species

Forest Ecosystems, 2021
Background National and international institutions periodically demand information on forest indicators that are used for global reporting. Among other aspects, the carbon accumulated in the biomass of forest species must be reported.

Dynamics of Foliar Responses to O3 Stress as a Function of Phytotoxic O3 Dose in Hybrid Poplar

Frontiers in Plant Science, 2021
With background concentrations having reached phytotoxic levels during the last century, tropospheric ozone (O3) has become a key climate change agent, counteracting carbon sequestration by forest ecosystems.

Experimental Design and Interpretation of Terrestrial Ecosystem Studies Using 15N Tracers: Practical and Statistical Considerations

Frontiers in Environmental Science, 2021
The stable isotope 15N is an extremely useful tool for studying the nitrogen (N) cycle of terrestrial ecosystems. The affordability of isotope-ratio mass spectrometry has increased in the last decades and routine measurements of δ15N with an accuracy ...
