    Tree decomposition

    A tree decomposition of graphG = (V, E) is referred to as a partition of edge setE into edge-disjoint trees. Given (not necessarily distinct) vertices u1, u2 ⋯ uk∈V with k⩾2, a sufficient and necessary condition ...

    (3,k)-Factor-Critical Graphs and Toughness

     A graph is (r,k)-factor-critical if the removal of any set of k vertices results in a graph with an r-factor (i.e. an r-regular spanning subgraph). Let t(G) denote the toughness of graph G. In this paper, we sho...

    On k- critical 2k- connected graphs

    A graph G is called an (n,k)-graph if κ(G-S)=n-|S| for any S ⊆ V(G) with |S| ≤ k, where ?(G) denotes the connectivity of G. Mader conjectured that for k ≥ 3 the graph K2k+2?(1-factor) is the uniqu...

    The effects of mycorrhizal associations on fine root decomposition in temperate and (sub)tropical forests

    Fine-root (diameter ≤ 2 mm) decomposition contributes significantly to nutrient cycling in terrestrial ecosystems. Roots with arbuscular mycorrhizas (AM) and ectomycorrhizas (ECM) differ in root chemistry, whi...

    Home-field advantage of litter decomposition differs among leaves, absorptive roots, and transport roots

    Home-field advantage (HFA) in litter decomposition occurs widely in terrestrial ecosystems, but it remains unknown that how leaf, absorptive and transport roots differ in their HFA. Here we conducted a 635-da...

    Persistence of soil microbial residuals and lignin phenols in forest ecosystems along the latitude gradient

    Soil organic carbon (SOC) storage is mainly governed by inputs from plant and microbial sources. How the relative contributions of these two sources in forest soils vary along broad-scale environmental gradien...
