Advancing restoration ecology: A new approach to predict time to recovery
Rydgren, Knut; Halvorsen, Rune; Töpper, Joachim Paul; Auestad, Inger; Hamre, Liv Norunn; Jongejans, Eelke; Sulavik, Jan (Journal article; Peer reviewed, 2018)1. Species composition is a vital attribute of any ecosystem. Accordingly, ecological restoration often has the original, or “natural,” species composition as its target. However, we still lack adequate methods for predicting ... -
How to induce defense responses in wild plant populations? Using bilberry (Vaccinium myrtillus) as example
Seldal, Tarald; Hegland, Stein Joar; Rydgren, Knut; Rodriguez-Saona, Cesar; Töpper, Joachim Paul (Journal article; Peer reviewed, 2017)Inducible plant defense is a beneficial strategy for plants, which imply that plants should allocate resources from growth and reproduction to defense when herbivores attack. Plant ecologist has often studied defense ... -
Multiannual effects of induced plant defenses: Are defended plants good or bad neighbors?
Benevenuto, Rafael Fonseca; Hegland, Stein Joar; Töpper, Joachim Paul; Rydgren, Knut; Moe, Stein Ragnar; Rodriguez-Saona, Cesar; Seldal, Tarald (Journal article; Peer reviewed, 2018)Defenses induced by herbivore feeding or phytohormones such as methyl jasmonate (MeJA) can affect growth, reproduction, and herbivory, not only on the affected individual but also in its neighboring plants. Here, we report ... -
The devil is in the detail: non-additive and context-dependent plant population responses to increasing temperature and precipitation. Plant demography in a warmer & wetter climate
Töpper, Joachim Paul; Meineri, E.; Olsen, Siri Lie; Rydgren, Knut; Skarpaas, Olav; Vandvik, Vigdis (Journal article; Peer reviewed, 2018)In climate‐change ecology, simplistic research approaches may yield unrealistically simplistic answers to often more complicated problems. In particular, the complexity of vegetation responses to global climate change begs ... -
Wooded hay meadows as viable production systems in sustainable small-scale farming
Rydgren, Knut; Austad, Ingvild; Hamre, Liv Norunn; Töpper, Joachim Paul (Peer reviewed; Journal article, 2020)Wooded hay meadows provide livestock fodder in the form of both foliage from pollarded trees and hay from the understorey, and can be part of an environmentally friendly agroforestry system. However, trees may also have a ...
