Carbon allocation during defoliation: testing a defence-growth trade-off in balsam fir

Frontiers in Plant Science, 2015
During repetitive defoliation events, carbon can become limiting for trees. To maintain growth and survival, the resources have to be shared more efficiently, which could result in a trade-off between the different physiological processes of a plant. The

The Effect of Canopy Architecture and Seasonal Variations on Several Seed Quality Attributes in Soybean (Glycine Max L. Merr.) [PDF]

, 2006
Producing high quality soybean seed in the hot humid tropics is no easy task. During seed production, several environmental factors and plant morphological characteristics can exert their influences on seed quality. A study was undertaken at Universiti

The enemy of my enemy: concomitant impacts of goat browsing on native vegetation during invasive plant control

Restoration Ecology, EarlyView.
The goal of invasive plant management is often to benefit native plants; however, the consequences of invasive plant management on native plants are not often assessed. While this is true generally for invasive plant management, it is particularly true for targeted grazing using livestock, such as goats, which is a rapidly expanding but little‐studied ...

Impacts of Highland cattle browsing on encroaching Alnus viridis shrubs

Restoration Ecology, EarlyView.
Abstract Introduction In several European mountain chains, the expansion of the tall shrub Alnus viridis into mountain pastures has altered vegetation structure and composition, reduced plant species diversity, and diminished forage quality. Recent woody encroachment research has explored the use of robust livestock breeds, such as Highland cattle (Bos

The influence of grazing on surface climatological variables of tallgrass prairie [PDF]

Mass and energy exchange between most grassland canopies and the atmosphere are mediated by grazing activities. Ambient temperatures can be increased or decreased by grazers.

Proposition of an index of intensity of grass use [PDF]

, 2013
A. The widely used concept of intensity of grassland management can be defined according to the fertilization level and defoliation frequency for mown meadows or to the stocking rate for pastures.

Developing and deploying an unmanned aerial system–based phenotyping program for maturity to support soybean breeding

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Soybean [Glycine max (L.) Merr.] varieties are categorized into different relative maturity groups (MGs) that correspond to the approximate region that the variety is best adapted. Maturity is an important trait that growers consider when deciding which varieties to plant and for breeders as a covariate to compare genotypes.
