A central question in ecology concerns how some exotic plants that occur at low densities in their native range are able to attain much higher densities where they are introduced. This question has remained unresolved in part due to a lack of experiments that assess factors that affect the population growth or abundance of plants in both ranges. We tested two hypotheses for exotic plant success...

Exotic plant invasions and chronic high levels of herbivory are two of the major biotic stressors impacting temperate forest ecosystems in eastern North America, and the two problems are often linked. We used a 4-ha deer exclosure maintained since 1991 to examine the influence of a generalist herbivore, white-tailed deer (Odocoileus virginianus), on the abundance of four exotic invasive (Rosa m...
تیره گاوزبان (boraginaceae s.str.) دارای حدود 100 جنس و 1600 گونه در دنیا با مرکز پراکنش در اوراسیا می باشد. riedl (1967) در جلد 48 مجموعه فلورا ایرانیکا برای این تیره 6 قبیله boragineae, cynoglosseae, eritrichieae, litospermeae, myosotideae و trigonotideae را در نظر گرفته است. قبیله cynoglosseae در ایران دارای 11 جنس و 53 گونه است. در پژوهش حاضر، فیلوژنی مولکولی قبیله cynoglosseae با تاکید بر ...
The angiosperm family Boraginaceae includes ca. 1600 species distributed among ca. 110 genera. Some floral features are constant within the family, but many vegetative, floral, pollen, and nutlet traits vary. Utilizing 224 species of Boraginaceae and related taxa, five matrices were constructed with various combinations of morphological characters, three chloroplast DNA regions, and one nuclear...
