Measuring forage mass on pastures to adjust stocking rate

, 2023
Grazing management practices play an important role in forage production and quality, and on sustainability of forage systems. Measuring forage mass allows for proper adjustments to the forage management plan, which will directly impact animal ...

Underground Signals: The Ecological Power of Root Volatiles

Advanced Science, EarlyView.
Root volatiles mediate rhizosphere chemical communication, shaping interactions among plants, microbes, herbivores, and natural enemies. Their production, transport, and perception underpin ecological adaptation, multitrophic interactions, and plant resilience, offering opportunities for sustainable crop protection, resilient agroecosystems, and ...

Mass Spectrometry Imaging of Specialized Metabolites for Predicting Lichen Fitness and Snail Foraging [PDF]

Plants, 2020
Lichens are slow-growing organisms supposed to synthetize specialized metabolites to protect themselves against diverse grazers. As predicted by the optimal defense theory (ODT), lichens are expected to invest specialized metabolites in higher levels in reproductive tissues compared to thallus.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Soil bulk density and biomass partitioning of Brachiaria decumbens in a silvopastoral system Densidade do solo e partição de biomassa de Brachiaria decumbens em um sistema silvopastoril

Scientia Agricola, 2010
Shade in silvopastoral systems improves the thermal comfort of animals, but it may also affect the pasture productivity and can contribute to soil compaction in the shaded areas due to the increase in the number of animals looking for comfort. The effect

Satisfying giant appetites : mechanisms of small scale foraging by large African herbivores [PDF]

, 2009
Variation in body mass allows for resource partitioning and co-existence of different species. Body mass is also seen as the main factor governing nutrient requirements in herbivores as metabolic rate and requirements have often been found to scale to ¾ ...

Methods for estimating forage mass in pastures. [PDF]

, 2020
A large part of farm properties have low levels of productivity, therefore estimate the herbage mass is essential for the proper planning, moreover, properly quantify the forage mass will provide appropriate information on the fertilization of forage ...

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

Advanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Calibration of Pasture Forage Mass to Plate Meter Compressed Height Is a Second‐Order Response with a Zero Intercept

, 2017
Core Ideas • Forage density has a linear relation to pasture height. • The regression of forage density to pasture height is a measure of plant morphology within the sward.

Average Mass of Seeds Encountered by Foraging Dabbling Ducks in Western Europe

Wildlife Biology, 2007
Many dabbling ducks Anas spp. are largely granivorous, consuming a variety of seeds chiefly from aquatic plants. To assess the relative value and carrying capacity of wetlands for dabbling ducks, species-specific information about seed mass is needed, but it is still largely missing or scattered in the literature.
