Native ungulates of diverse body sizes collectively regulate long-term woody plant demography and structure of a semi-arid savanna - Sankaran - 2013 - Journal of Ecology - Wiley Online Library

Native ungulates of diverse body sizes collectively regulate long-term woody plant demography and structure of a semi-arid savanna - Sankaran - 2013 - Journal of Ecology - Wiley Online Library | Trees, Shrubs & Herbivores | Scoop.it

"In semi-arid rangelands, intact communities of native browsing ungulates ... provide a critical ecosystem service by regulating woody cover, and their removal (or extinction) from these systems can lead to rapid woody encroachment."

Peter Scogings's insight:

Yes!

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.

A systematic review of the attractant-decoy and repellent-plant hypotheses: do plants with heterospecific neighbours escape herbivory?

A systematic review of the attractant-decoy and repellent-plant hypotheses: do plants with heterospecific neighbours escape herbivory? | Trees, Shrubs & Herbivores | Scoop.it
The repellent-plant hypothesis was well supported in many ecological systems, particularly for mammalian herbivores, but the attractant-decoy hypothesis has been less frequently tested, thereby representing an important research gap. Insect herbivores were under-represented in all categories except in applied contexts such as commercial forestry and agriculture. There is a clear need for studies to connect these two ecological hypotheses with the management of agriculture and restoration efforts in many ecosystems. Research on the co-evolution and facilitation between palatable and unpalatable plants also represents another novel area of future study.

Were Fertile Crescent crop progenitors higher yielding than other wild species that were never domesticated? - Preece - 2015 - New Phytologist - Wiley Online Library

Were Fertile Crescent crop progenitors higher yielding than other wild species that were never domesticated? - Preece - 2015 - New Phytologist - Wiley Online Library | Trees, Shrubs & Herbivores | Scoop.it
there was no intrinsic yield advantage to adopting large-seeded progenitor species as crops. Explaining why Neolithic agriculture was founded on these species, therefore, remains an important unresolved challenge.

A complex allometric model of biomass was developed based on a model of resource partition between dbh and height growths. Although being a good model for biomass prediction, the power model was outperformed by the complex allometric model.

The phylogenetic distribution of ant-plants shows that domatia evolved from a range of pre-adapted morphological structures and have been lost frequently, suggesting that domatia have no generalizable effect on diversification. The Miocene origin of ant–plant symbioses is consistent with inferred changes in diet and behaviour during ant evolution.

"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."
