Wanted: new allometric equations for large lianas and African lianas [PDF]

open access: yesBiotropica, 2016
AbstractLiana abundance appears to be increasing, possibly to the detriment of trees, but methods for measuring liana biomass are undependable. We show that five commonly used allometric equations produce disparate results and discuss two large information gaps—Central African lianas and large lianas—that currently preclude accurate liana biomass ...

Immunomodulatory Peptide LW‐9 Enhances Doxorubicin Efficacy by Downregulating PD‐L1 and Promoting Intratumoral T‐Cell Responses in Murine Breast Cancer

open access: yesImmunology, EarlyView.
LW‐9, a peptide derived from Phoneutria nigriventer venom, enhances antitumor immunity in a murine breast cancer model by remodelling the tumour microenvironment. Treatment reduces PD‐L1 expression while increasing CD3+ and GITR+ T‐cell infiltration, resulting in delayed tumour progression, particularly when combined with doxorubicin.

A posttranslational proteomic survey of a single anatomically preserved human 20‐week postconception brain

open access: yesJournal of Anatomy, EarlyView.
A well‐preserved 20 post‐conception week human brain was obtained and finely dissected into 18 anatomically distinct regions, including the pia mater. Each region underwent in‐depth proteomic analysis, encompassing both total protein content and post‐translational modifications.

Trait‐based plant ecology: some history and some future

open access: yesNew Phytologist, EarlyView.
Schematic of plant species range boundaries, some mechanisms that might set them, and some traits that might explain them. Summary Since around the year 2000, trait‐based ecology has become self‐aware as a strand of research within ecology. How did this happen? What is trait‐based ecology now? And where might it go in future?

Diversity and aboveground biomass of lianas in the tropical seasonal rain forests of Xishuangbanna, SW China

open access: yesRevista de Biología Tropical, 2009
Lianas are important components of tropical forests and have significant impacts on the diversity, structure and dynamics of tropical forests. The present study documented the liana flora in a Chinese tropical region.

Environmental heterogeneity influences liana community differentiation across a Neotropical rainforest landscape

open access: yesEcology and Evolution
We examined the variation in liana community composition and structure across geopedological land units to test the hypothesis that environmental heterogeneity is a driving force in liana community assembly.

Wood Anatomical and Demographic Similarities Between Self-Standing Liana and Tree Seedlings in Tropical Dry Forests of Colombia

open access: yesPlants
Canopy lianas differ considerably from trees in terms of wood anatomical structure, and they are suggested to have a demographic advantage—faster growth and higher survival—than trees.

Terrestrial Laser Scanning to Detect Liana Impact on Forest Structure

open access: yesRemote Sensing, 2018
Tropical forests are currently experiencing large-scale structural changes, including an increase in liana abundance and biomass. Higher liana abundance results in reduced tree growth and increased tree mortality, possibly playing an important role in ...
