Shrub-depth: Capturing Height of Dense Graphs [PDF]
Logical Methods in Computer Science, Volume 15, Issue 1 (January
31, 2019) lmcs:3798, 2017 The recent increase of interest in the graph invariant called tree-depth and in its applications in algorithms and logic on graphs led to a natural question: is there an analogously useful "depth" notion also for dense graphs (say; one which is stable under graph complementation)? To this end, in a 2012 conference paper, a new notion of shrub-depth has

Shrub expansion in tundra ecosystems: dynamics, impacts and research priorities [PDF]
, 2011 Part of Focus on Dynamics of Arctic and Sub-Arctic Vegetation Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1)

Evolutionary lability underlies drought adaptation of Australian shrubs along aridity gradients
Frontiers in Plant Science, 2022 Leaf drought tolerance traits influence plant survival in water deficit conditions, and these traits are influenced by both the plant’s evolutionary history and the environment in which the plant is currently growing.

Understory effect on tree and cork growth in cork oak woodlands
Forest Systems, 2018 Aim of study: Cork oak is one of the main forest tree species in Portugal that typically occurs in montado, where operational practices oriented to the tree, crop or animal management may influence several of the ecosystem components. This study aimed at

Frontiers in Forests and Global Change, 2023 IntroductionSurvival and growth of tree seedlings are key processes of regeneration in forest ecosystems. However, little is known about how climate warming modulates seedling performance either directly or in interaction with understory vegetation and ...
