Herbivory and plant biodiversity in an arctic environment

Åsa Lindgren; Johan Ehrlén; Roger Bergström; et al. 2005

Other claims from this paper (14)

Intervention effect Reindeer grazing in southern Lapland had limited effects on plant community composition and seedling germination.
Association Reindeer presence influenced plant functional traits, particularly in the subalpine birch forest.
Intervention effect Tall herbs had lower SLA when reindeer were present.
Intervention effect Tall herbs were lower when reindeer were present.
Association Small herbs showed an opposite pattern to tall herbs in plant functional traits when reindeer were present.
Mechanism The contrasting effects on the two herb groups are probably explained by competitive release for small herbs when reindeer suppress tall herbs.
Association Rodents had the largest relative impact on plant community composition in southern Lapland.
Intervention effect With no predators present, vole densities increased.
Association With no predators present, voles almost depleted some dwarf shrub species.
Mechanism Small mammals in arctic and alpine tundra are probably controlled by predators (top-down).
Intervention effect Defoliation of a sedge decreased its nutritional quality.
Association In Beringia, large herbivores were related to plant species richness.
Association In Beringia, small herbivores were related to plant abundance.
Association Plant functional traits in Beringia were related only to large herbivores and standing crop of vascular plants.

Other claims from this paper (11)

Observation Rates of reduction and solution Fe buildup varied among Llanos soils and moisture and cultivation histories.
Intervention effect Water-management treatments reduced soil-solution Fe.
Intervention effect Large lime additions reduced soil-solution Fe.
Intervention effect MnO 2 additions reduced soil-solution Fe.
Association Rice oranging symptoms increased as solution Fe concentration increased.
Association Large rice plants were more seriously affected by oranging than small plants.
Observation Few active white roots formed after Fe concentration increased.
Mechanism The authors attribute rice oranging mainly to Fe-induced deficiency of P, K, Ca and Mg.
Mechanism Fe-coated roots may have reduced nutrient absorption.
Mechanism Excessive Fe absorption can cause rice bronzing symptoms under certain conditions.
Mechanism Combined direct and indirect Fe toxicity may produce a range of rice oranging intensities and brown leaf streaks.
