A framework for predicting intraspecific variation in plant defense
One of the most well-supported theories regarding the evolution of plant defenses is the
resource availability hypothesis (RAH). RAH posits that species from high-resource …

Sources of controversy surrounding latitudinal patterns in herbivory and defense
Both herbivory and plant defenses against herbivores have been predicted to increase
toward tropical regions. Early tests of this latitudinal herbivory-defense hypothesis (LHDH) …

Latitudinal variation in plant chemical defences drives latitudinal patterns of leaf herbivory
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 …

Latitudinal variation in herbivory: influences of climatic drivers, herbivore identity and natural enemies
Although a number of investigations have concluded that lower latitudes are associated with
increases in herbivore abundance and plant damage, the generality of this pattern is still …

Latitudinal variation in herbivory: hemispheric asymmetries and the role of climatic drivers
S Zhang, Y Zhang, K Ma - Journal of Ecology, 2016 - Wiley Online Library
In the past, it was widely accepted that herbivory decreased with latitude. However, several
empirical studies have failed to support this hypothesis, leading to strong debate. In addition …

Rapid evolution of latitudinal clines in growth and defence of an invasive weed
Re‐establishment of heritable latitudinal clines in growth‐related traits has been recognised
as evidence for adaptive evolution in invasive plants. However, less information is known …

Background invertebrate herbivory on dwarf birch (Betula glandulosa-nana complex) increases with temperature and precipitation across the tundra biome
Chronic, low intensity herbivory by invertebrates, termed background herbivory, has been
understudied in tundra, yet its impacts are likely to increase in a warmer Arctic. The …

Latitudinal patterns of herbivore pressure in a temperate herb support the biotic interactions hypothesis
CA Baskett, DW Schemske - Ecology Letters, 2018 - Wiley Online Library
The longstanding biotic interactions hypothesis predicts that herbivore pressure declines
with latitude, but the evidence is mixed. To address gaps in previous studies, we measured …

Can genetically based clines in plant defence explain greater herbivory at higher latitudes?
Greater plant defence is predicted to evolve at lower latitudes in response to increased
herbivore pressure. However, recent studies question the generality of this pattern. In this …

Geographical variation in community‐wide herbivory matches patterns of intraspecific variation instead of species turnover
Aim Attempts over the past 30 years to explain geographical variation in the strength of
herbivore pressure have given rise to ecological hypotheses like the latitudinal herbivory …
