The overlooked contribution of trees outside forests to tree cover and woody biomass across Europe
Science Advances, 2023 Trees are an integral part in European landscapes, but only forest resources are systematically assessed by national inventories. The contribution of urban and agricultural trees to national-level carbon stocks remains largely unknown.

From Local Explanations to Global Understanding with Explainable AI for Trees
Nature Machine Intelligence, 2020 Tree-based machine learning models such as random forests, decision trees and gradient boosted trees are popular nonlinear predictive models, yet comparatively little attention has been paid to explaining their predictions.

Constitutive and insect‐induced transcriptomes of weevil‐resistant and susceptible Sitka spruce
Plant-Environment Interactions, 2021 Spruce weevil (Pissodes strobi) is a significant pest of regenerating spruce (Picea) and pine (Pinus) forests in North America. Weevil larvae feed in the bark, phloem, cambium, and outer xylem of apical shoots, causing stunted growth or mortality of ...

Journal of Logic and Analysis, 2020 We show the theory of pointed $\R$-trees with radius at most $r$ is axiomatizable in a suitable continuous signature. We identify the model companion $\rbRT_r$ of this theory and study its properties. In particular, the model companion is complete and has quantifier elimination; it is stable but not superstable.

A note on r-equitable k-colorings of trees [PDF]
Yugoslav Journal of Operations Research, 2014 A graph G = (V;E) is r-equitably k-colorable if there exists a partition of V into k independent sets V1, V2,... Vk such that ||Vi|- |Vj|| ≤ r for all i,j {1,2... k}.

On the Extremal Trees for Some Bond Incident Degree Indices with a Fixed Number of Segments
Journal of Chemistry, 2022 The Gourava indices and hyper-Gourava indices are introduced by Kulli in 2017. These graph invariants are related to the degree of vertices of a graph G. Let Tn,r be the class of all n−vertex chemical trees with r segments. In this paper, we characterize

Dynamic changes in rhizosphere bacterial communities of Rhododendron simsii at different growth stages [PDF]
Botanica SerbicaRhododendron simsii plays important roles in maintaining ecological system stability in the north temperate zone. However, its natural growth is greatly affected by soil microorganisms, particularly rhizosphere microbes.
