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."

Rapid root elongation by phreatophyte seedlings does not imply tolerance of water table decline - Springer

Rapid root elongation by phreatophyte seedlings does not imply tolerance of water table decline - Springer | Trees, Shrubs & Herbivores | Scoop.it
Despite high rates of root elongation during phreatophyte establishment, once connection to groundwater has occurred and leaf area develops, seedlings demonstrate limited capacity for root elongation in response to groundwater decline.

Associational relationships at multiple spatial scales affect forest damage by moose

the abundance and quality of alternative browse was negatively related to pine browsing (i.e. associational resistance) at several spatial scales, with the highest explanatory power at the largest spatial scale.

Floristic composition in relation to environmental gradients across KwaZulu-Natal, South Africa - Jewitt - 2014 - Austral Ecology - Wiley Online Library

Floristic composition in relation to environmental gradients across KwaZulu-Natal, South Africa - Jewitt - 2014 - Austral Ecology - Wiley Online Library | Trees, Shrubs & Herbivores | Scoop.it
warmer temperatures may facilitate the spread of frost sensitive savanna species into previously cooler, grassland areas. Species associated with specific soil types will not easily be able to move up the altitudinal gradient to cooler climes because geology is aligned in an approximately north-south direction compared with increasing altitude from east-west.

Analysis of plant leaf metabolites reveals no common response to insect herbivory by Pieris rapae in three related host-plant species

Analysis of plant leaf metabolites reveals no common response to insect herbivory by Pieris rapae in three related host-plant species | Trees, Shrubs & Herbivores | Scoop.it
The absence of common metabolites among the plants meant these induced responses could not be related to the performance of the herbivore. Thus, the response to herbivory by the same herbivore in these three host plants has evolved to be idiosyncratic in terms of the specific metabolites induced.

Red:far-red light conditions affect the emission of volatile organic compounds from barley (Hordeum vulgare), leading to altered biomass allocation in neighbouring plants

Red:far-red light conditions affect the emission of volatile organic compounds from barley (Hordeum vulgare), leading to altered biomass allocation in neighbouring plants | Trees, Shrubs & Herbivores | Scoop.it
Total VOC emissions by ‘Alva’ were reduced under low R:FR conditions compared with control light conditions, although individual volatile compounds were found to be either suppressed, induced or not affected by R:FR. The altered composition of the VOC blend emitted by ‘Alva’ plants exposed to low R:FR was found to affect carbon allocation in receiver plants of ‘Kara’.
