Locally chordal graphs

open access: yes
A graph is locally chordal if, locally at each vertex, it is chordal, i.e. composed of cliques glued along a tree. In addition to extending many classic characterizations of chordal graphs, we show that locally chordal graphs are precisely those graphs $G$ which can be decomposed into cliques arranged in the shape of a high-girth graph.

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

open access: yesJournal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

On an edge partition and root graphs of some classes of line graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2017
The Gallai and the anti-Gallai graphs of a graph $G$ are complementary pairs of spanning subgraphs of the line graph of $G$. In this paper we find some structural relations between these graph classes by finding a partition of the edge set of the line ...

Differences in characteristics between naturalized threatened plants and other threatened plants

open access: yesConservation Biology, EarlyView.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.
