Dipsacus Sylvestris

Dipsacus sylvestris Huds., wild teasel, is an introduced weed of pastures, abandoned fields and roadsides occurring in widely-spaced but very dense patches in southern Ontario, Quebec, northeastern U.S.A., and northwestern U.S.A. Original research and information from other studies are incorporated into a summary of the biology of this fugitive plant species.

Common Mullein

Verbascum thapsus L., common mullein, and V. blattaria L., moth mullein, are introduced weeds of pasture, abandoned fields, and roadsides occurring in widely-spaced, but dense patches in Southern Ontario, Quebec, the Maritime Provinces, British Columbia and throughout the U.S.A. Original research and information from other studies are incorporated into a summary of the biology of these two fugitive plant species.

Composition Pattern

Spatial dimension of abandoned fields has been expanding more in rural subalpine zones of Nepal leading to various patterns of secondary succession. The secondary succession in the subalpine Himalayas has not yet been evaluated. Here, I describe a study initiated in Manang district, Central Nepal where enough abandoned fields of different chronosequences were located. A definitive successional pattern was predicted from the data obtained from sampling 256 plots of 1 × 1 m2 each systematically in a total of 43 abandoned fields from 1 to 55 years after abandonment. Change in composition pattern of 11 most important plant species was analyzed through the Detrended Correspondence Analysis (DCA). The first two axes of DCA explained 19.1 % of the total variation in the species composition. Early, mid and late successions were three stages distinguished each by their abundance scores and life-forms composition. Malva neglecta, Phleum alpinum and Fagopyrum esculentum were dominant at the recently abandoned fields. Cynoglossum zeylanicum, Malaxis muscifera, Medicago falcata and Pennisetum flaccidum were mid succession species, and Thymus linearis, Tanacetum gossypinum, Pinus wallichiana and Poa annua represented the late succession species.doi: http://dx.doi.org/10.3126/botor.v8i0.5553 Botanica Orientalis – Journal of Plant Science (2011) 8: 10-15

Number Of Plant Species

AbstractAn attraction to certain plant species by Bombus terricola, B. bimaculatus, B. perplexus, and B. ternarius was observed. The gathering of pollen was observed as a behavioural act distinct from nectar gathering. Pollen analyses indicated that pollen collectors restricted their activities to a small number of plant species. These bees’ life histories and flower preferences made them potentially effective pollinators of early-flowering economic crops, Ribes spp., and Pyrus Malus in particular, and of common weeds such as Solanum Dulcamara and Hypericum perforatum. The same reasons prevented them from being important in the pollination of Trifolium pratense and Medicago sativa.

Scientific progress is like doing a puzzle, not building a wall

AbstractWe contest the “building a wall” analogy of scientific progress. We argue that this analogy unfairly privileges original research (which is perceived as laying bricks and, therefore, constructive) over replication research (which is perceived as testing and removing bricks and, therefore, destructive). We propose an alternative analogy for scientific progress: solving a jigsaw puzzle.
