Ecological niche differentiation in peripheral populations: a comparative analysis of eleven Mediterranean plant species

G Papuga, P Gauthier, V Pons, E Farris… - Ecography, 2018 - Wiley Online Library
The 'central‐peripheral'hypothesis has provided a baseline for many studies of population

Soil nitrogen mediates the effect of climatic distance on herbivory rates in a tropical herb

JK Moutouama, OG Gaoue - Biotropica, 2022 - Wiley Online Library
The center‐periphery hypothesis predicts that species are most abundant at the center of

Enemy release at range edges: do invasive species escape their herbivores as they expand into new areas?

JSH Wan, SP Bonser - Journal of Plant Ecology, 2016 - academic.oup.com
Aims We test the hypothesis that invasive plant species at their range edges experience
lower herbivory and allocate less to defense at the edge of an expanding range edge than …
