Genomic loci associated with leaf abscission contribute to machine picking and environmental adaptability in upland cotton (Gossypium hirsutum L.)

Journal of Advanced Research
Introduction: Defoliation by applying defoliants before machine picking is an important agricultural practice that enhances harvesting efficiency and leads to increased raw cotton purity.

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

Oikos, EarlyView.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Defoliation Dynamics on Grazing Horizons in Pastures Intercropped by Panicum maximum, Brachiaria brizantha, and Brachiaria decumbens

Tropical Animal Science Journal, 2020
The aim of this study was to quantify and verify the defoliation dynamics process of the Panicum maximum, Brachiaria brizantha, and Brachiaria decumbens intercropping during the formation of four grazing horizons in lenient grazing intensities and high ...

Crop protection. Visit to the GODPC / SIAT / Nucleus estate - smallholders and outgrowers : 23 to 28 February 2004 [PDF]

, 2004
The time allowed for the visit was very short, so it was not possible to carry out a more detailed and more meticulous analysis than the one presented in this report.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

Oikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Simulated elephant foraging alters tree root exudation rates: Species‐specific responses and implications for belowground carbon dynamics in tropical forests

PLANTS, PEOPLE, PLANET, EarlyView.
Asian elephants play crucial roles in ecosystem functioning, and their interactions with plants influence above‐ and belowground carbon cycling. We tested whether their mechanically destructive foraging triggers short‐term, stress‐induced shifts in tree root exudation, an underappreciated pathway linking herbivory to belowground carbon processes.
