Control of arthropod abundance by Anolis lizards on St. Eustatius (Neth. Antilles)

Pacala, Stephen, Roughgarden, Jonathan·1984·Oecologia

Abstract

The two Anolis lizard species of St. Eustatius (Neth. Antilles) have large effects on the abundance of arthropods. Over a six-month period, we excluded Anolis lizards from three experimental areas and maintained three other areas with natural densities of lizards. Exclusion of anoles resulted in a two to three-fold increase in the abundance of arthropods on the forest floor (mainly Dipterans), and a twenty to thirty-fold increase in the abundance of three large web-building spiders. These abundant web-building spiders, in turn, caused approximately a 25% decrease in the abundance of insects between the forest floor and canopy. Exclusion of anoles had no observed effect on the degree of herbivory as assayed by the amount of leaf damage on two plant species.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • The counter cascade of arthropod declines despite predator decreases conflicts with decades of research on trophic dynamics and with studies documenting the major impact of anoles, frogs, and birds on arthropod abundance.

    “This “counter cascade” conflicts with decades of research on trophic dynamics (44), as well as studies documenting the major impact of anoles, frogs, and birds on arthropod abundance (45, 46).”

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.
