Does large herbivore removal affect secondary metabolites, nutrients and shoot length in woody species in semi-arid savannas?

Scogings, Peter F.; Hjältén, Joachim; Skarpe, Christina (Journal article; Peer reviewed, 2013)

We hypothesised that exclusion of long-term browsing leads to decreased nutrient concentrations, increased carbon-based secondary metabolites (CBSMs) and decreased shoot length in woody plants in semi-arid savannas. To ...
Nutrient and secondary metabolite concentrations in a savanna are independently affected by large herbivores and shoot growth rate

Scogings, Peter F.; Hjältén, Joakim; Skarpe, Christina; Hattas, Dawood; Zobolo, Alpheus; Dziba, Luthando; Rooke, Tuulikki (Journal article; Peer reviewed, 2014)

Carbon-based secondary metabolites (CBSMs) such as tannins are assumed to function as plant defences against herbivores. CBSMs are thought to be inversely related to growth rate and nutrient concentrations because a ...
Secondary metabolites and nutrients of woody plants in relation to browsing intensity in African savannas

Scogings, Peter F.; Hjältén, Joachim; Skarpe, Christina (Journal article; Peer reviewed, 2011)

Abstract Carbon-based secondary metabolites (CBSMs) are assumed to function as defences that contribute to herbivore-avoidance strategies of woody plants. Severe browsing has been reported to reduce concentrations of CBSMs ...
