Rising CO2 drives divergence in water use efficiency of evergreen and deciduous plants
Science Advances, 2019 A rapid rise in CO2 has made evergreen trees more waterwise than deciduous trees, especially in cooler parts of the world. Intrinsic water use efficiency (iWUE), defined as the ratio of photosynthesis to stomatal conductance, is a key variable in plant ...

National mapping and estimation of forest area by dominant tree species using Sentinel-2 data [PDF]
, 2020 Nation-wide Sentinel-2 mosaics were used with National Forest Inventory (NFI) data for modelling and subsequent mapping of spruce, pine and deciduous forest in Norway in 16 m $\times$ 16 m resolution. The accuracies of the best model ranged between 74% for spruce and 87% for deciduous forest.

Nature Communications, 2019 Leaf unfolding in temperate forests is driven by spring temperature, but little is known about the spatial variance of that temperature dependency. Here we use in situ leaf unfolding observations for eight deciduous tree species to show that the two ...

Assessment of Tooth Shade in Primary Dentition among Indian Paediatric Population and its Association with Skin, Lip and Gingival Colour: An Observational Study [PDF]
Journal of Clinical and Diagnostic Research, 2018 Introduction: Assessment of dental aesthetics is a complex procedure because a large number of factors can contribute to aesthetic perceptions. These factors include hard tissue characteristics such as tooth colour, shape and alignment, and soft tissue ...

Tree size distribution as the stationary limit of an evolutionary master equation [PDF]
arXiv, 2023 The diameter distribution of a given species of deciduous trees in mature, temperate zone forests is well approximated by a Gamma distribution. Here we give new experimental evidence for this conjecture by analyzing deciduous tree size data in mature semi-natural forest and ancient, traditionally managed wood-pasture from Central Europe.
