Grazing patterns on signalgrass pasture according to location of cattle feces

Revista Brasileira de Zootecnia, 2012
This study was conducted to evaluate the defoliation patterns on B. decumbens cv. Basilisk (signalgrass) tiller as a function of influence of feces deposited naturally by cattle.

Effect of Post-grazing Sward Height on Ingestive Behavior, Dry Matter Intake, and Milk Production of Holstein Dairy Cows

Frontiers in Animal Science, 2021
Sward height is strongly related to the daily dry matter intake of grazing dairy cows, which consequently determines animal performance. Despite that, few studies have explored the potential to increase milk production by managing post-grazing sward ...

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 ...

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.

Defoliation, Shoot Plasticity, Sward Structure and Herbage Utilization in Pasture: Review of the Underlying Ecophysiological Processes

Agriculture, 2015
Sward structure affects herbage growth, pasture species dynamics, and herbage utilization. Defoliation management has a major impact on sward structure.

Efecto de la defoliación post-quema sobre el crecimiento de dos gramíneas nativas en el Caldenal, Argentina [PDF]

, 2009
El crecimiento en los pastizales naturales semiáridos puede ser afectado por la longitud de tiempo que el pastoreo es excluido durante el período de regeneración post-fuego.

Development and adoption of Kernza—A perennial grain crop for sustainable agriculture

PLANTS, PEOPLE, PLANET, EarlyView.
Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...

Bidirectional interactions between beet armyworm and its host in response to different fertilization conditions. [PDF]

PLoS ONE, 2018
Fertilizer with different ratios of nitrogen (N) to phosphorus (P) can influence crop plant performance and defense against herbivores. Spodoptera exigua is an important agricultural pest that has caused serious economic loss, especially in recent ...
