The paper presents evidence that Roger Bacon was endeavoring to structure what he considered as a “new metaphysics”. Moreover, it identifies the Opus maius Bacon’s new preliminary text in metaphysics and morals. is found Communia naturalium mathematica, which one finds reference sketch for metaphysics. From part seven of latter work, namely, Moralis philosophia, can see views work closely conne...

The herbarium of Hans Sloane in the Natural History Museum’s Department of Botany is a cunning object: a book of colonial nature that contains ethnographic artefacts in the guise of natural specimens. The eight volumes of Sloane’s specimens from his Jamaican voyage of 1687–1689 hold both dried plants and sample foodstuffs, many together with the original drawings prepared for the engravings of ...

PREMISE OF THE STUDY Because legumes can add nitrogen (N) to ecosystems through symbiotic fixation, they play important roles in many plant communities, such as prairies and grasslands. However, very little research has examined the effect of projected climate change on legume growth and function. Our goal was to study the effects of temperature on growth, nodulation, and N chemistry of prairie...

Plant species, plant community diversity and microbial interactions can significantly impact soil microbial communities, yet there are few data on the interactive effects of plant species and plant community diversity on soil bacterial communities. We hypothesized that plant species and plant community diversity affect soil bacterial communities by setting the context in which bacterial interac...

abstract the aim of this experiment was the study of freezing tolerance of bellis perennis under controlled conditions and were arranged in a completely randomized design with three replications. plants after sowing and grow in the bed, at the middle of autumn (after hardening in natural conditions), in the 7-8 leaf stage put on the thermogradiant freezer with the 12 freezing temperatures (0,-2...

many different plant species synthesize triterpenoid saponins as part of their normal programme of growth and development. examples include plants that are exploited as sources of drugs. interest in these molecules stems from their medicinal properties, antimicrobial activity, and their likely role as determinants of plant disease resistance. daisy (bellis perennis l.) accumulates triterpenoid ...

Despite the high biodiversity in Mediterranean region, use of wildflowers from mountain areas urban landscaping projects is hampered by limited information on their seed germination performances. This research evaluated traits 14 native herbaceous wildflower species northern west Italian alpine and subalpine areas. Seed Petri dishes at 25 °C was performed, applying two different photoperiod con...
