The Impact of Plant Diversity on Carbon Storage Along the Gradient of Altitude in Alpine Grasslands of the Qinghai–Tibetan Plateau

Grasses
Plant diversity plays an important role in shaping the carbon cycling of grassland ecosystems. However, differences in the diversity effect on aboveground and belowground carbon storage remains unclear at specific spatiotemporal scales.

Intraspecific variation in stomatal architecture, gas exchange, and drought response of a dominant prairie grass sourced from broad climatic gradients

American Journal of Botany, EarlyView.
Abstract Premise Understanding how plant populations adapt to water limitation through stomatal traits is key to predicting drought responses. The dominant C4 grass Andropogon gerardi, distributed across sharp climate gradients in North America, offers an excellent focal species to study stomatal architecture (size and density).

Accounting for Diurnal Variation in Enteric Methane Emissions from Growing Steers Under Grazing Conditions

Grasses
Automated head chamber systems (AHCS) are increasingly deployed to measure enteric emissions in vivo. However, guidance for AHCS-derived emissions data analyses pertains to confined settings, such as feedlots, with less instruction for grazing systems ...

Perennial Forage Trial Dr. Heather [PDF]

, 2015
In 2015, the University of Vermont Extension Northwest Crops and Soils Program initiated a trial investigating forage yield, quality, and nitrogen use efficiency of cool season perennial grasses alone and in combination with red clover. The grass species

Wind‐driven seed dispersal differentially promotes seed trapping and retention across alpine plants

American Journal of Botany, EarlyView.
Abstract Premise Seed dispersal can mediate species interactions between plants across life stages. Plants can physically stop seed movement (seed trapping) and prevent further dispersal following entrapment (seed retention). We therefore hypothesized seed trapping and retention rates depend on the physical attributes of interacting seeds and plants ...

Dryland Fodder Radish Genotypes: Planting Date Effects on Nutritive Value and In-Vitro Dry Matter Degradability in Midlands of KwaZulu-Natal, South Africa

Grasses
Erratic rainfall and extended dry periods challenge forage production and livestock feed sustainability in dryland agriculture regions. This study investigated the effects of planting dates and genotype selection on the nutritive value and in-vitro dry ...

Herbicide impacts on exotic grasses and a population of the critically endangered herb "Calystegia affinis" (Convolvulaceae) on Lord Howe Island [PDF]

, 2013
Introduced perennial grasses are capable of altering the habitat of native species, causing reductions in population size and vigour, and potentially affecting life-history processes such as survival, pollination and seedling recruitment. We examined the

The sleeping giant needs coffee: Overlooked areas for integrating plant ecophysiology and evolutionary biology

American Journal of Botany, EarlyView.
Abstract Interpretations of evolutionary outcomes are limited without incorporation of physiological ecology, and ecophysiological interpretations would benefit from incorporating evolutionary perspectives. Although there has been a rise of studies in the last 20 years between these fields, evolutionary studies that incorporate plant physiology have ...

Effect of Light on Yield, Nutritive Value of Brachiaria decumbens, and Soil Properties in Silvopastoral Systems, Peruvian Amazon

Grasses
Silvopastoral systems, integrating trees, forages, and livestock, are recognized as a sustainable approach to livestock production. This study evaluated the effect of shade vs.
