Arboreal twig-nesting ants form dominance hierarchies over nesting resources. [PDF]

open access: yes, 2019
Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been

Allometric scaling models for tree saplings: Assessing potential fodder for ungulate herbivores

open access: yesTrees, Forests and People, 2023
Knowledge of the quantity of twig dry mass (available fodder) of saplings is crucial for understanding tree recruitment under wild ungulate browsing pressure in forest ecosystems. Therefore, this study aimed to develop allometric equations for estimating

Holistic Twig Joins: Optimal XML Pattern Matching [PDF]

open access: yes, 2002
XML employs a tree-structured data model, and, naturally, XML queries specify patterns of selection predicates on multiple elements related by a tree structure. Finding all occurrences of such a twig pattern in an XML database is a core operation for XML

Increased precipitation and nitrogen alter shrub architecture in a desert shrubland: implications for primary production

open access: yesFrontiers in Plant Science, 2016
Shrublands are one of the major types of ecosystems in the desert regions of northern China, which is expected to be substantially more sensitive to global environmental changes, such as widespread nitrogen enrichment and precipitation changes, than ...

Black Twig Borer, Xylosandrus compactus (Eichhoff) (Insecta: Coleoptera: Scolytidae)

open access: yesEDIS, 2023
The black twig borer, Xylosandrus compactus (Eichhoff), is one of the few ambrosia beetles that infests healthy plants. In Florida, orchids (Dendrobium spp. and Cattleya spp.), and avocado (Persea americana Mill.) have sustained notable economic losses (

Biogeographic patterns of structural traits and C:N:P stoichiometry of tree twigs in China's forests.

open access: yesPLoS ONE, 2015
There have been a number of studies on biogeographic patterns of plant leaf functional traits; however, the variations in traits of other plant organs such as twigs are rarely investigated. In this study, we sampled current-year twigs of 335 tree species
