Increasing liana abundance and biomass in tropical forests: emerging patterns and putative mechanisms: Increasing lianas in tropical forests

Open access

Abstract

Tropical forests are experiencing large-scale structural changes, the most apparent of which may be the increase in liana (woody vine) abundance and biomass. Lianas permeate most lowland tropical forests, where they can have a huge effect on tree diversity, recruitment, growth and survival, which, in turn, can alter tree community composition, carbon storage and carbon, nutrient and water fluxes. Consequently, increasing liana abundance and biomass have potentially profound ramifications for tropical forest composition and functioning. Currently, eight studies support the pattern of increasing liana abundance and biomass in American tropical and subtropical forests, whereas two studies, both from Africa, do not. The putative mechanisms to explain increasing lianas include increasing evapotranspirative demand, increasing forest disturbance and turnover, changes in land use and fragmentation and elevated atmospheric CO₂. Each of these mechanisms probably contributes to the observed patterns of increasing liana abundance and biomass, and the mechanisms are likely to be interrelated and synergistic. To determine whether liana increases are occurring throughout the tropics and to determine the mechanisms responsible for the observed patterns, a widespread network of large-scale, long-term monitoring plots combined with observational and manipulative studies that more directly investigate the putative mechanisms are essential.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In the degraded forest trajectory, feedbacks often involve competition between trees and other opportunistic plants, as well as interactions between deforestation, fire and seed limitation.

    “In the ‘degraded forest’ trajectory, feedbacks often involve competition between trees and other opportunistic plants85,90,92, as well as interactions between deforestation, fire and seed limitation84,87,105.”

    From Critical transitions in the Amazon forest system (2024) · cites this paper as [90]

    The citation is attached to the clause about competition between trees and opportunistic plants, not the separate clause about deforestation, fire and seed limitation. The available passages labeled Abstract contain bibliographic details and the keyword “below-ground competition,” but no substantive passage establishing the claimed feedback in degraded forests. Searches for tree–liana competition and degraded-forest feedbacks returned no relevant text. (LLM, conf=0.72)

    Experimental — accuracy not yet measured
  • Liana forests can be relatively stable because lianas self-perpetuate by causing physical damage to trees, allowing lianas to remain at high density.

    “Liana forests can also be relatively stable, because lianas self-perpetuate by causing physical damage to trees, allowing lianas to remain at high density90,91.”

    From Critical transitions in the Amazon forest system (2024) · cites this paper as [90]

    The supplied passages contain bibliographic metadata but no discussion of liana-dominated forest stability. Further searches for physical tree damage, self-perpetuation, and feedbacks affecting liana density returned no substantive passage, so this claim cannot be checked against our copy. (LLM, conf=0.72)

    Experimental — accuracy not yet measured
  • Liana forests are expected to expand with increasing aridity, disturbance regimes and CO2 fertilization.

    “Liana forests are expected to expand with increasing aridity, disturbance regimes and CO2 fertilization90.”

    From Critical transitions in the Amazon forest system (2024) · cites this paper as [90]

    The available indexed passages contain bibliographic information and keywords, including “elevated atmospheric co2,” but no discussion of whether liana forests will expand. Searches for aridity, disturbance, CO2 fertilization, and increasing liana abundance returned no passage stating the claimed relationship. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
