A strong decline in species richness from the equator to the poles is a common feature of Earthâs biodiversity. However, little is known about how phenotypic diversity varies across the same latitud
<b>Abstract</b><br/>Plant defences against herbivores are predicted to evolve to be greater in warmer climates, such as lower latitudes where herbivore pressure is also thought to be
A long-standing paradigm in ecology holds that herbivore pressure and thus plant defences increase towards lower latitudes. However, recent work has challenged this prediction where studies have found
1. Geographic variation in abiotic factors and species interactions is widespread and is hypothesized to generate concomitant patterns of species trait variation. For example, higher rates of herbivor
