Phenocams, cameras that monitor leaf function, offer a promising new method to track and detect the impact of climate change on ecosystems, helping conservation efforts and ensuring long-term resilience.

Impacts of herbivory on perennial grass species of the Northern Great Basin
How does herbivory impact the survival and growth of three perennial grass species commonly used to revegetate dryland ecosystems?

Drought response of European beech trees is not straight forward
Drought and rising temperatures can cause massive forest diebacks around the world. When a tree is experiencing drought, “shedding off” the leaves can enhance tree water status by reducing canopy transpiration. Whilst...

Connecting soil nitrogen and gypsy moth herbivory in a US oak forest
Can a better understanding of ecosystem nitrogen cycling allow us to more accurately predict invasive insect outbreaks?
Not All Pine Needles Are Identical: Lower Crown Loss in Pinus radiata
When fungal infection comes to Pinus radiata, it can run through the bottom of the crown of the tree, removing its leaves. What effect does this defoliation have when it occurs? Mireia Gomez-Gallego and colleagues...

Males become female when striped maples take a health hit
Above a certain trauma threshold, male trees had a high probability of becoming female, possibly in a bid to better their chances at reproduction.

Carbon stores support efficient nitrate use during regrowth of perennial ryegrass
Plant regrowth in response to defoliation relies on efficient nitrogen use. Roche et al. find that remobilisation of water soluble carbohydrate stores in leaves of perennial ryegrass (Lolium perenne) is coordinated with...

Effects of elevated atmospheric CO2 concentrations, clipping regimen and differential day/night atmospheric warming on tissue nitrogen concentrations of a perennial pasture grass
Forecasting the effects of climate change on nitrogen (N) cycling in pastures requires an understanding of changes in tissue N. A new study published in AoB PLANTS by Volder et al. shows that elevated CO2, climate...

Defoliation, tree growth and storage of C and N
Although lenga beech trees, completely defoliated by caterpillars of Ormiscodes amphimone, do not die, they show reduced growth for at least 2 years.
Trampling, defoliation and physiological integration
Clonal plants are a common feature of heavily grazed ecosystems where large herbivores inflict simultaneous pressures of trampling and defoliation. Xu et al. examine the effects of physiological integration (resource...
Reproduction costs when photosynthate is limited
Reproduction imposes a cost as resources are diverted from other functions within the plant. Ida et al. use both defoliation and shading to reduce photosynthate supply in fully pollinated plants of a perennial legume...
