Variation in local herbivore pressure along elevation gradients is predicted to drive variation
in plant defense traits. Yet, the extent of intraspecific variation in defense investment along …

Glucosinolates are commonly found in Arabidopsis thaliana and its crucifer relatives, which
are known for their role in defense against insect herbivory. In a common garden …

The spatial distribution of plant defenses within a leaf may be critical in explaining patterns
of herbivory. The generalist lepidopteran larvae, Helicoverpa armigera (the cotton …

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 …

Alpine plants occurring at high elevation are vulnerable to ongoing climate change, yet
relatively little is known about the potential for high‐elevation species to adapt to changing …

Natural populations of wild cabbage (Brassica oleracea) show significant qualitative
diversity in heritable aliphatic glucosinolates, a class of secondary metabolites involved in …

Ecological theory indicates that warmer and more stable climates should result in stronger
biotic interactions. Therefore, plant species growing at lower elevations and experiencing …

Ecological gradients shape the evolution of plant functional traits through variation in
climate, abiotic factors, and biological processes. While recent observations highlight …

Plants protect themselves against herbivore attacks through a myriad of physical structures
and toxic secondary metabolites. Together with abiotic factors, herbivores are expected to …

The geographic mosaic theory of coevolution states that variation in species interactions
forms the raw material for coevolutionary processes, which take place over large geographic …
