Lianas decelerate tropical forest thinning during succession

, 2022
The well-established pattern of forest thinning during succession predicts an increase in mean tree biomass with decreasing tree density. The forest thinning pattern is commonly assumed to be driven solely by tree-tree competition.

Abundância e biomassa de lianas em um fragmento de floresta Atlântica

Hoehnea
Lianas representam um importante componente da estrutura e diversidade das florestas tropicais. Normalmente em florestas perturbadas são encontradas uma alta densidade de lianas em comparação com florestas não perturbadas.

Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia

, 2008
: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.

Temperate Lianas Have More Acquisitive Strategies than Host Trees in Leaf and Stem Traits, but Not Root Traits

Plants, 2022
Increasingly, tropical studies based on aboveground traits have suggested that lianas have a more acquisitive strategy than trees, thereby possibly explaining the increase in lianas relative to trees in many tropical forests under global change. However,

Efficiency-safety in lianas and trees

, 2019
Hydraulic traits are important for woody plant functioning and distribution. Associations among hydraulic traits, other leaf and stem traits, and species’ performance are relatively well understood for trees, but remain poorly studied for lianas.

Change in liana density over 30 years in a Bornean rain forest supports the escape hypothesis

Ecosphere, 2021
Liana dynamics may influence tree dynamics and vice versa. Only long‐term studies can perhaps disentangle them. In two permanent plots of lowland dipterocarp forest at Danum, a liana census in 1988 was repeated in 2018.

Extraction of Liana Stems Using Geometric Features from Terrestrial Laser Scanning Point Clouds

Remote Sensing, 2022
Lianas are self-supporting systems that are increasing their dominance in tropical forests due to climate change. As lianas increase tree mortality and reduce tree growth, one key challenge in ecological remote sensing is the separation of a liana and ...

Association between patient safety culture, adverse events, and essential practices during childbirth in six Brazilian maternity hospitals

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective This study examines whether hospitals with stronger patient safety culture more consistently follow essential birth practices and have fewer adverse outcomes for mothers and newborns and whether this evidence can guide maternity care priorities in patient safety policy.

Two decades of change in Ghanaian forests [PDF]

, 2012
Understanding the impacts and synergies of the many threats facing tropical forests is a key research challenge. Here, three potential threats are addressed: drought, fire and lianas.
