Precipitation and habitat fragmentation impact population dynamics of a tropical understory plant

Delayed effects and habitat fragmentation: are we underestimating the effects of anthropogenic change?

Anthropogenic climate change is causing an increased frequency and severity of extreme precipitation events (i.e. droughts and unusually wet conditions). At the same time, human development and land conversion interrupts and fragments previously …

Habitat-dependent delayed effects of climate on demographic vital rates in a fragmented Amazonian landscape

**Background** Deforestation is a major threat to species biodiversity in the Amazon rainforest. Deforestation results in loss of habitat, but also often leaves remaining forest habitat highly fragmented, with remnants of different sizes embedded in …

Delayed effects of climate on vital rates lead to demographic divergence in Amazonian forest fragments

Deforestation often results in landscapes where remaining forest habitat is highly fragmented, with remnants of different sizes embedded in an often highly contrasting matrix. Local extinction of species from individual fragments is common, but the …

Impacts of insect herbivory on tea quality: strategies for a changing climate

Differing non‐linear, lagged effects of temperature and precipitation on an insect herbivore and its host plant

1. Multivariate climate change is expected to impact insect densities and plant growth in complex, and potentially different, ways. Tea (Camellia sinensis) is a unique crop system where the increase in quality from chemical defences induced by …

The effects of climate change on tea quality mediated by insect herbivory

The most popular beverage in the world, tea, is made from the leaves of the tea plant (Camellia sinensis). The flavor, aroma, and health benefits of tea are determined by plant secondary metabolites. Changes in tea secondary metabolites such as …

Differential Changes in Tea Quality as Influenced by Insect Herbivory

Tea quality depends on plant metabolites that impact flavor, aroma, and health beneficial properties. Plants respond to insect herbivory by altering the concentration and blend of these metabolites and many secondary metabolites are produced only …

The importance of insect herbivore density to induced metabolite blends in tea plants (Camellia sinensis) and implications for tea quality.

🏆 First place in section. Plant metabolic responses to herbivory are generally elucidated using experiments that compare the metabolite concentrations in attacked plants to un-attacked plants. In these experiments, herbivore density is often …

Interactive effects of drought severity and herbivory on tea (Camellia sinensis) volatile and non-volatile metabolites.

Poster presentation. Plants often experience multiple sources of stress simultaneously, yet little is known about interactive effects of multiple stressors on plant metabolic responses. Plants are well known to respond to both drought and insect …
