Taxon: tree ✕

A claim can belong to several research areas, so group counts add up to more than the total.

Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Organism groups follow NCBI Taxonomy: the spellings of one organism are merged, a claim naming several organisms sits in each group, and claims whose value names no organism are under “not stated”.

Title

Combining Climber Cutting and Tree Seedling Planting Improves Structural Attributes of a Seasonal Semideciduous Forest in Southeastern Brazil

Guilherme Aparecido Melo dos Santos; Valéria Forni Martins; Ana Carolina Cardoso de Oliveira; et al. Biotropica 2025. doi:10.1111/btp.70023

Other claims from this paper (7)

Intervention effect Cutting plus planting most decreased climber basal area.
Intervention effect Cutting plus planting most increased large living tree density.
Intervention effect Both strategies reduced large dead tree percentage, with cutting having the greater effect.
Intervention effect Cutting plus planting increased tree sapling richness.
Intervention effect Management did not affect large living tree basal area.
Intervention effect Management did not affect tree sapling density.
Recommendation The authors advocate cutting plus planting as the best tested restoration strategy.
