Message from the curator | Trees, Shrubs & Herbivores | Scoop.it

Dear Reader, Thank you for viewing my Scoop.it page. This page is where I share links to many of the articles that attract my attention and that I add to my library of journal articles, which is stored in a shared Dropbox folder. When I scoop an article, I might also quote a sentence or two from the abstract that I feel most eloquently summarises the key findings of the article. Visit my Yolasite page to read about my research, find abstracts of my publications on Academia, or connect with me on LinkedIn or Twitter. All the best, Peter.

Secondary metabolites and nutrients of woody plants in relation to browsing intensity in African savannas - Oecologia, Volume 167, Number 4 - SpringerLink

Secondary metabolites and nutrients of woody plants in relation to browsing intensity in African savannas - Oecologia, Volume 167, Number 4 - SpringerLink | Trees, Shrubs & Herbivores | Scoop.it

"The model suggests that species with low allocation of C to C-based defence traits become C-limited (potentially more palatable) at higher browsing intensity than species with high allocation of C to C-based defences. The model also suggests that when N availability is high, plants become C-limited at higher browsing intensity than when N availability is low."

Population size structure of trees in a semi‐arid African savanna: Species differ in vulnerability to a changing environment and reintroduction of elephants

Population size structure of trees in a semi‐arid African savanna: Species differ in vulnerability to a changing environment and reintroduction of elephants | Trees, Shrubs & Herbivores | Scoop.it
savanna tree species apparently ensure persistence based on individualistic responses to population perturbations, but persistence of some following the reintroduction of elephants may be threatened if certain size classes experience escalated mortality

The Effects of Interannual Rainfall Variability on Tree–Grass Composition Along Kalahari Rainfall Gradient

The Effects of Interannual Rainfall Variability on Tree–Grass Composition Along Kalahari Rainfall Gradient | Trees, Shrubs & Herbivores | Scoop.it
In relatively wet environments, grasses are favored because of their high growth rate that allows them to take advantage of the window of opportunity existing in years with above average precipitation and thus increase fire-induced tree mortality.

Seedling tolerance to cotyledon removal varies with seed size: A case of five legume species

Seedling tolerance to cotyledon removal varies with seed size: A case of five legume species | Trees, Shrubs & Herbivores | Scoop.it
The overall effect of cotyledon removal on growth and survival varies with seed size (i.e., energy reserves) with seedlings from small seeds being less sensitive than those from large seeds under field conditions.

Combined effects of deer, mice and insect seed predation on the reproductive success of a Mediterranean shrub - ScienceDirect

Combined effects of deer, mice and insect seed predation on the reproductive success of a Mediterranean shrub - ScienceDirect | Trees, Shrubs & Herbivores | Scoop.it
seed predation by mice was irrelevant, but ungulate and invertebrate seed predation interacted to strongly limit the reproductive success of C ladanifer, potentially affecting plant population dynamics in the long-term.

Woody-plant ecosystems under climate change and air pollution — response consistencies across zonobiomes? | Tree Physiology | Oxford Academic

Woody-plant ecosystems under climate change and air pollution — response consistencies across zonobiomes? | Tree Physiology | Oxford Academic | Trees, Shrubs & Herbivores | Scoop.it

"Ecosystem warming results in trade-offs between respiration and biomass production, affecting high elevation forests more than in the lowland tropics and low-elevation temperate zone. Resilience to drought is modulated by tree size and species richness. Elevated O3 tends to counteract stimulation by elevated carbon dioxide (CO2). Biotic stress and genomic structure ultimately determine ecosystem responsiveness. Insect herbivory is exacerbated by CC–AP in biome-specific ways."

Pervasive interactions between foliar microbes and soil nutrients mediate leaf production and herbivore damage in a tropical forest | Trees, Shrubs & Herbivores | Scoop.it

Sensing Danger: Key to Activating Plant Immunity - ScienceDirect

Sensing Danger: Key to Activating Plant Immunity - ScienceDirect | Trees, Shrubs & Herbivores | Scoop.it
Immunogenic plant host factors can be roughly divided into two categories: molecules which are passively released upon cell damage (‘classical’ damage-associated molecular patterns, DAMPs), and peptides which are processed and/or secreted upon infection to modulate the immune response (phytocytokines).

Nitrogen nutrition in plants: rapid progress and new challenges | Journal of Experimental Botany | Oxford Academic

Nitrogen nutrition in plants: rapid progress and new challenges | Journal of Experimental Botany | Oxford Academic | Trees, Shrubs & Herbivores | Scoop.it
As a main feature of plant autotrophy, assimilation of inorganic nitrogen is not only of fundamental scientific interest, but also a crucial factor in crop productivity. In its broad sense – from root uptake of various forms of N in the soil to allocation of N assimilates to different organs – it involves a wide range of physiological processes whose mechanisms are far from being fully understood.

Herbivory‐induced jasmonates constrain plant sugar accumulation and growth by antagonizing gibberellin signaling and not by promoting secondary metabolite production

Herbivory‐induced jasmonates constrain plant sugar accumulation and growth by antagonizing gibberellin signaling and not by promoting secondary metabolite production | Trees, Shrubs & Herbivores | Scoop.it
Simulated herbivore attack by Manduca sexta specifically reduced leaf sugar concentrations and growth in a jasmonate-dependent manner. These effects were similar or even stronger in defenseless genotypes with intact jasmonate signaling. Gibberellin complementation rescued carbohydrate accumulation and growth in induced plants without impairing the induction of defensive secondary metabolites.
