We monitored individual plants of winterberry (Ilex verticil/ala), highbush cranberry (Viburnum opulus), wild lily-of-the-valley (Maianthemum canadense), and partridgeberry (Mitchel/a repens) during two reproductive seasons to measure the disappearance of fruits (presumably removed by fruit-eating animals) in plant species whose fruits ripen in early fall but persist through the winter. Pattern...

Broccoli (Brassica oleracea L. var. italica Plenck) and caulifl ower (B. oleracea var. botrytis DC) are closely related botanical varieties. The underlying genetic bases of their phenotypic differences from each other are not well understood. A molecular genetic marker enabling B. oleracea germplasm curators and breeders to predict phenotype from seeds or seedlings would be a valuable tool. Mut...

Within the past decade, Scrophulariaceae sensu lato has been shown to be polyphyletic and, as a result, is currently undergoing major systematic revision. The traditionally recognized family is now generally considered to comprise several smaller families including the newly expanded Plantaginaceae, a family of 12 tribes, 92 genera, and approximately 2000 species. Recent evidence from molecular...

Al-Shehbaz (in Harvard Pap. Bot. 19: 58. 2014) (Cruciferae), based on L. (Sp. 1753) and formerly known as Malcolmia Spreng. (Syst. Veg. 2: 899. 1825), is currently applied to an annual or perennial plant distributed in Spa...

The effects of the methanol extracts of the leaves of Phyllanthus amarus on the sperm parameters of male Guinea pigs were investigated. The effects of Vitamin E on the sperm parameters were also investigated and compared to that of Phyllanthus amarus. The phytochemical screening of the leaves of Phyllanthus amarus was also carried out. The methanol extract of the Phyllanthus amarus leaf (50-200...

Oilseed pennycress (Thalspi arvense L.) is a crop that has undergone domestication for use as new oilseed option in parts of the United States biofuel and livestock feed production but does not yet have management resources such growth staging guide. Winter types this may utility existing summer annual rotations throughout much U.S. Midwest by growing during fall/winter fallow period. This guid...

Of 23 orchid species studied at Barra Colorado National Monument in central Panama, 16 were found to produce extrafloral nectar. Extrafloral nectaries were found primarily on reproductive structures and developing shoots. Only one species (Caularthron bilamellatum) showed evidence of ant occupation, indicating that most orchids are not likely to derive nutritional benefit from their association...

As revised here, Discocarpus is interpreted to consist of three neotropical species: D. essequeboensis Klotzsch, D. gentryi S. M. Hayden, which is described and named herein as new to science, and D. spruceanus Mull. Arg. One previously accepted name, D. brasiliensis Klotzsch ex Mull. Arg., is reduced to synonymy of D. essequeboensis. Lectotypes are proposed for the two species previously descr...

The thesis entitled "Cellular and molecular mechanisms involved in themorphological and functional alterations of the renal glomerulus in aging andhypertension" is aimed to identify new molecular mechanisms associated with thedevelopment of cellular senescence of the renal glomerular cells in physiological agingand hypertension. The content of this thesis is structured in two pa...
