Exploitative Competition Between Invasive Herbivores Benefits A Native Host Plant, Joseph Elkinton, E. L. Preisser Oct 2008

Exploitative Competition Between Invasive Herbivores Benefits A Native Host Plant, Joseph Elkinton, E. L. Preisser

Joseph Elkinton

Although biological invasions are of considerable concern to ecologists, relatively little attention has been paid to the potential for and consequences of indirect interactions between invasive species. Such interactions are generally thought to enhance invasives' spread and impact (i.e., the “invasional meltdown” hypothesis); however, exotic species might also act indirectly to slow the spread or blunt the impact of other invasives. On the east coast of the United States, the invasive hemlock woolly adelgid (Adelges tsugae, HWA) and elongate hemlock scale (Fiorinia externa, EHS) both feed on eastern hemlock (Tsuga canadensis). Of the two insects, HWA is considered far more …

Effect Of Surfactants On Bioherbicidal Activity Of Alternaria Helianthi On Multiple-Seeded Cocklebur, Prasanta C. Bhowmik, H. K. Abbas, D. Sanyal Jan 2008

Effect Of Surfactants On Bioherbicidal Activity Of Alternaria Helianthi On Multiple-Seeded Cocklebur, Prasanta C. Bhowmik, H. K. Abbas, D. Sanyal

Prasanta C. Bhowmik

Abstract: Multiple-seeded cocklebur (Xanthium strumarium L.) is a biotype which has different morphology and higher seedling production ability than common cocklebur. Greenhouse studies were conducted to investigate the bioherbicidal activity of Alternaria helianthi (Hansf.) Tubaki and Nishih. on multiple-seeded cocklebur as affected by various rates of Tenkoz COC® (crop oil concentrate), Activator 90® (non-ionic surfactant), BAS 9050 0 S® (methylated oil), Silwet L-77® (organosilicone surfactant) and Top film® (natural based surfactant). Taking X as the recommended rate for each surfactant, 0-X, ¼-X, ½-X, X and 2-X rates were used for each of the surfactants. Surfactants were added to the conidial …

Comparative Analysis Of Multiple Disease Resistance In Ryegrass And Cereal Crops, Young-Ki Jo, Reed Barker, William Pfender, Scott Warnke, Sung-Chur Sim, Geunhwa Jung Jan 2008

Comparative Analysis Of Multiple Disease Resistance In Ryegrass And Cereal Crops, Young-Ki Jo, Reed Barker, William Pfender, Scott Warnke, Sung-Chur Sim, Geunhwa Jung

Geunhwa Jung

Ryegrass (Lolium spp.) is among the most important forage crops in Europe and Australia and is also a popular turfgrass in North America. Previous genetic analysis based on a three-generation interspecific (L. perenne 9 L. multiflorum) ryegrass population identified four quantitative trait loci (QTLs) for resistance to gray leaf spot (Magneporthe grisea) and four QTLs for resistance to crown rust (Puccinia coronata). The current analysis based on the same mapping population detected seven QTLs for resistance to leaf spot (Bipolaris sorokiniana) and one QTL for resistance to stem rust (Puccinia graminis) in ryegrass for the first time. Three QTLs for …

Nectar Secondary Compounds Affect Self-Pollen Transfer: Implications For Female And Male Reproduction, Rebecca E. Irwin, Lynn Adler Jan 2008

Nectar Secondary Compounds Affect Self-Pollen Transfer: Implications For Female And Male Reproduction, Rebecca E. Irwin, Lynn Adler

Lynn Adler

Pollen movement within and among plants affects inbreeding, plant fitness, and the spatial scale of genetic differentiation. Although a number of studies have assessed how plant and floral traits influence pollen movement via changes in pollinator behavior, few have explored how nectar chemical composition affects pollen transfer. As many as 55% of plants produce secondary compounds in their nectar, which is surprising given that nectar is typically thought to attract pollinators. We tested the hypothesis that nectar with secondary compounds may benefit plants by encouraging pollinators to leave plants after visiting only a few flowers, thus reducing self-pollen transfer. We …
