The dominance of invasive species is often assumed to reflect their competitive superiority over displaced native species. However, invasive species may be abundant because of their greater tolerance to anthropogenic impacts accompanying their introduction. Thus, invasive species can either be the drivers or passengers of change.We distinguish between these two possibilities in California grass...

This study identifies the prevalence of vaginal flora alterations in low-risk pregnant women and their association with reported symptoms and gynecological exams. This quantitative, descriptive, cross-sectional study was conducted in public primary care service units in Botucatu, SP, Brazil from 2006 to 2008 with 289 pregnant women from a stratified sample obtained by sampling by care unit. Tes...

Both the continental or island origin of Hainan, and the Indo-Malaysian or East Asian affinity of its flora, are debatable. In this study, 196 families, 1283 genera and 3894 species of Hainan plants were recognized. Patterns of seed plant distribution were quantified at the generic and the family levels. The floras of Vietnam, and the adjacent Guangxi and Guangdong provinces of mainland China, ...

The flora of Laos is composed of 5,005 species in 1,373 genera and 188 families of seed plants. Floristic and geographical attributes of the flora were analyzed. Tropical floristic elements at the family and generic levels contributed a majority (62.23% of the families and 82.30% of the genera) of the flora, of which the dominant geographical elements were pantropical distribution (42.02% of fa...

Microorganisms are a necessary part of everyday life. Many, known as resident or normal flora, adapt and live peacefully with the human body, providing benefits such as vitamin production or cellulose digestion in the intestines, and protection from disease-producing pathogens. Transient flora may stay for weeks to months but do not remain permanently because of fierce competition from resident...

Comment #1. Detoxification of Cr(VI) in the organism I started working on this subject more than 30 years ago, by investigating Cr(VI) reduction in blood and liver (e.g., S. De Flora, Nature 271, 455-6, 1978; F.L. Petrilli and S. De Flora, Mutat. Res. 54, 139-147, 1978), in the respiratory tract (e.g., F.L. Petrilli et al., J. Clin. Invest. 77, 1917-24, 1986; S. De Flora et al., Cancer Res. 47,...

Newberiy's I860 Catalogue of 1,377 species was the first annotated checklist of Ohio's vascular plants. Five similar works were published during the next 72 years. The last, Schaffner's 1932 Catalog, listed 2,309 species. Since 1950, studies for the Ohio Flora Project and related projects have produced further additions to the known flora. In 1961,1 estimated that Ohio's vascular plant flora wo...

the areas of the world that have mediterranean style climate are found at about 35 degrees north and south of the equator, on the western sides of continents. the distinctive feature of this climate is the small amount of rain in the summer. overall, the climate has a moderate amount of rainfall and warm winters and hot summers and. the climate of the mediterranean region is conditioned by its ...

The Flora-On dataset currently includes 253,310 occurrence records for the class Embryopsidae (vascular plants), comprising data collated via the platform http://flora-on.pt/ relating to observation records of vascular plants across mainland Portugal. Observations are uploaded directly to the database primarily by experienced botanists and naturalists, typically on a weekly basis, and consist o...
