Nomenclatural And Taxonomic Notes On Some Centaurea Taxa (Asteraceae) From Southern Italy, Emanuele Del Guacchio, Duilio Iamonico, Paola Cennamo, Paolo Caputo Jan 2020

Nomenclatural And Taxonomic Notes On Some Centaurea Taxa (Asteraceae) From Southern Italy, Emanuele Del Guacchio, Duilio Iamonico, Paola Cennamo, Paolo Caputo

Turkish Journal of Botany

We studied the application of the neglected name Centaurea leucolepis DC., concluding, by examination of the literature and original material, that the associated taxon is C. corensis Vals. et Filig., endemic to Campania region (southern Italy) and introduced into Sardinia. The name by Candolle is legitimate and it is here lectotypified by a specimen kept at G. In addition, after field surveys and herbarium searches, we suggest that this taxon should be considered as a subspecies of C. deusta Ten., a very polymorphic species of south-eastern Europe, proposing a new combination and providing a detailed description. In addition, we provide …

The Economics Of On-Farm Rice Drying In Arkansas, Clayton J. Parker, Lanier Nalley Jan 2020

The Economics Of On-Farm Rice Drying In Arkansas, Clayton J. Parker, Lanier Nalley

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Globally, rice producers are faced with the temporal problem of deciding the optimal time to harvest rice. When harvested, paddy rice is typically at a harvest moisture content (HMC) between 15% and 22% and subsequently dried by the mill to a moisture content (MC) of 12.5%. Riceland Foods Inc., the largest miller of rice in the world, uses a stair-step pricing model to charge farmers to dry, which can complicate the timing of harvest as producers try to balance the tradeoff of minimizing drying costs by waiting to harvest at lower HMC vs. maintaining higher rice quality typically observed when …

The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sulfur dioxide is an inorganic compound (IC) and air pollutant that causes health risks in humans. The buildup of sulfur dioxide (SO2) in enclosed indoor spaces is, therefore, a concern to human health, especially since the average person spends 90% of his/her time indoors. This study focused on decreasing SO2 concentration in a cost-effective and simple way—by using botanical biofiltration, or the uptake of pollutants by plants. Research in biofiltration has focused mostly on the remediation of volatile organic compounds (VOC). However, research has also shown that plant species that remediate VOC efficiently also have the potential for efficient IC …

The Role Of Fire And A Fire-Free Interval In The Restoration Of Upland Oak Communities On The Cumberland Plateau, Kentucky, Jordan Winkenbach Jan 2020

The Role Of Fire And A Fire-Free Interval In The Restoration Of Upland Oak Communities On The Cumberland Plateau, Kentucky, Jordan Winkenbach

Theses and Dissertations--Forestry and Natural Resources

The decline of upland oak (Quercus spp.) communities in our eastern forests has been attributed to the loss of periodic disturbance after decades of fire suppression. As land managers have begun to reintroduce fire, effects on oak regeneration and species composition have varied widely, making it apparent that our understanding of how fire can aid in oak forest management needs refinement. Restoring upland oak communities requires decreasing stand density and opening of the canopy to release shade-intolerant oaks in the understory. This necessitates an extended fire-free interval to allow these oaks to be recruited into larger size classes and …

Benchmarking The Agronomic Performance Of Biodegradable Mulches Against Polyethylene Mulch Film: A Meta‐Analysis, Mauro B.D. Tofanelli, Samuel E. Wortman Jan 2020

Benchmarking The Agronomic Performance Of Biodegradable Mulches Against Polyethylene Mulch Film: A Meta‐Analysis, Mauro B.D. Tofanelli, Samuel E. Wortman

Department of Agronomy and Horticulture: Faculty Publications

Growers are interested in biodegradable alternatives to petroleum‐based polyethylene mulch film (PEM). However, many growers cite limited knowledge about biodegradable mulch films (BDMs) as a significant barrier to adoption. Agronomic field tests of BDMs are often limited temporally or spatially, and the variability of performance results relative to PEM may be contributing to this perceived knowledge gap. Our objective was to use data available in the scientific literature to provide the first quantitative performance benchmark of BDMs against PEM. We extracted data from 66 articles for meta‐analysis. Response ratios were calculated for comparison of BDMs relative to black PEM, and …

Growth And Development, From: Forages: The Science Of Grassland Agriculture, Volume Ii, Robert B. Mitchell, Daren Redfearn, Kenneth J. Moore Jan 2020

Growth And Development, From: Forages: The Science Of Grassland Agriculture, Volume Ii, Robert B. Mitchell, Daren Redfearn, Kenneth J. Moore

Department of Agronomy and Horticulture: Faculty Publications

The growth and development of forage plants is an amazing process. In some annual grasses such as cereal rye, plants can go from the late vegetative stage to fully-flowered in less than two weeks. Conversely, some perennial grasses like indiangrass can go from the vegetative stage to the elongation stage, then enter a quiescent phase for several weeks until adequate moisture is available which then moves plants into the flowering stages to complete the seed production process. Understanding the developmental morphology of forage plants is important for making good management decisions. Many such decisions involve timing the initiation or termination …

Land-Use Type As A Driver Of Large Wildfire Occurrence In The U.S. Great Plains, Victoria M. Donovan, Carissa L. Wonkka, David A. Wedin, Dirac Twidwell

Department of Agronomy and Horticulture: Faculty Publications

Wildfire activity has surged in North America’s temperate grassland biome. Like many biomes, this system has undergone drastic land-use change over the last century; however, how various land-use types contribute to wildfire patterns in grassland systems is unclear. We determine if certain land-use types have a greater propensity for large wildfire in the U.S. Great Plains and how this changes given the percentage of land covered by a given land-use type. Almost 90% of the area burned in the Great Plains occurred in woody and grassland land-use types. Although grassland comprised the greatest area burned by large wildfires, woody vegetation …

Wild Geranium, Geranium Maculatum, 2020 Virginia Wildflower Of The Year, W. John Hayden Jan 2020

Wild Geranium, Geranium Maculatum, 2020 Virginia Wildflower Of The Year, W. John Hayden

Biology Faculty Publications

Geranium maculatum was named by Linnaeus in his monumental Species Plantarum, published in1753. Geranium has long served as the type genus of Geraniaceae. The genus and family name are derived from the Greek word geranos, crane, in reference to the elongate fruiting styles common throughout the family. English common names like Cranesbill and Storksbill for relatives of Wild Geranium similarly refer to their elongate fruiting-stage styles. The species portion of the binomial, maculatum, means spotted, perhaps a reference to slight irregularities in petal pigmentation sometimes observed in this species.

The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler Jan 2020

The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler

Cal Poly Humboldt theses and projects

Early successional wetland habitat is being lost in temperate regions worldwide as a result of changes in disturbance regimes that allow for the establishment and dominance of woody species. In particular, this phenomenon is pronounced in fens, which harbor high numbers of rare herbaceous species that require early successional habitat. I investigated the relationship between woody vegetation encroachment and herbaceous species diversity within a Northern California coastal fen that has been undergoing encroachment by woody vegetation for ca. 80 years by recording species richness and cover data from 338 permanent plots throughout the fen.
