Message from the curator

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.

Recurrent Mild Drought Events Increase Resistance Toward Extreme Drought Stress - Springer

Recurrent Mild Drought Events Increase Resistance Toward Extreme Drought Stress - Springer | Trees, Shrubs & Herbivores | Scoop.it

"Recurrent mild drought stress seems to improve drought resistance of plant communities and species. Potential reasons could be epigenetic changes or soil biotic legacies. Morphological legacies such as altered root to shoot ratio did not play a role..."

Exclusion of herbivores slows down recovery after experimental warming and nutrient addition in an alpine plant community - Olsen - 2014 - Journal of Ecology - Wiley Online Library

Exclusion of herbivores slows down recovery after experimental warming and nutrient addition in an alpine plant community - Olsen - 2014 - Journal of Ecology - Wiley Online Library | Trees, Shrubs & Herbivores | Scoop.it

"...a shift in dominance hierarchies in arctic and alpine plant communities due to global change is not readily reversible. Herbivory may, however, facilitate plant community recovery."

Plant succession as an integrator of contrasting ecological time scales

Plant succession as an integrator of contrasting ecological time scales | Trees, Shrubs & Herbivores | Scoop.it

"...plant succession can be central to the development of a framework that integrates a spectrum of ecological processes, which occur over time scales ranging from seconds to millions of years. This novel framework helps us understand the impacts of human perturbations on successional trajectories, ecosystem recovery, and global environmental change."

Faecal nutritional indicators in relation to the comparative population performance of sable antelope and other grazers - Macandza - 2013 - African Journal of Ecology - Wiley Online Library

Faecal nutritional indicators in relation to the comparative population performance of sable antelope and other grazers - Macandza - 2013 - African Journal of Ecology - Wiley Online Library | Trees, Shrubs & Herbivores | Scoop.it

"Although faecal nutrient levels for sable appeared only marginally limiting under the conditions that prevailed during the study, malnutrition could have contributed to the population decline by sable during a persistently low-rainfall period."

Anthropogenic effects on population structure of Acacia tortilis subsp. raddiana along a gradient of water availability in South Sinai, Egypt - Abd El-Wahab - 2013 - African Journal of Ecology - Wi... | Trees, Shrubs & Herbivores | Scoop.it

"The variation in water availability may have considerable effects on the structure of A. tortilis. Overgrazing, cutting and urbanization are the main causes of population decline of Acacia in Sinai desert. In addition, drought conditions and bruchid seed beetles aggravate the anthropogenic effect on recruitment of Acacia in South Sinai."

"... ‘nutritional niches’ segregate the forest and along with other factors, such as generalist and specialist feeding strategies and differences in body size and requirements for shelter, presumably minimise competition between the marsupial species."

"...variation in tree cover is the dominant biotic driver of C, N and P dynamics in these savanna systems in the top 10 cm of soil, ...herbivores primarily affect soil moisture content, ...canopy and herbivore effects tend to be additive rather than synergistic.

Relative growth rate variation of evergreen and deciduous savanna tree species is driven by different traits

Relative growth rate variation of evergreen and deciduous savanna tree species is driven by different traits | Trees, Shrubs & Herbivores | Scoop.it

"...differences in drivers of RGR occur among savanna species because these have different selected strategies for coping with fire disturbance in savannas. It is expected that variation in the drivers of RGR will be found in other functional types that respond differently to particular disturbances."

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."

Quantifying the response of free-ranging mammalian herbivores to the interplay between plant defense and nutrient concentrations - Springer | Trees, Shrubs & Herbivores | Scoop.it

"...equal concentrations of chemical defenses provide nutrient-poor plants with relatively greater protection as nutrient-rich plants. Nutrient-rich plants may therefore face the exacerbated problem of being preferred by herbivores and therefore need to produce more defense compounds to achieve the same level of defense as nutrient-poor plants."
