Pale swallow-wort (Vincetoxicum rossicum [Kleopow] Barbar.) and black swallow-wort (V. nigrum [L.] Moench), European species of herbaceous, perennial viny milkweeds, have become increasingly invasive in various natural and managed habitats in the northeastern United States and southeastern Canada, including low- and high-light habitats. A classical biological control program is being developed,...

Effective control techniques for pale swallowwort (PSW), an invasive herbaceous vine of old fields and forest understories, are limited. We conducted a 3-yr cutting and herbicide study on an adjacent old-field and forest understory site near Ithaca, NY, for control of PSW. Plants in experimental plots were cut in early July and cut again or sprayed in late August for two seasons with the isopro...

Abstract Giuseppe Raddi collected in the state of Rio de Janeiro, Brazil, from November 1817 to June 1818. He published 12 new names family Piperaceae an article that appeared 1828. Raddi's has not been cited specialized literature and these were never properly studied. In present study, are typified, their identity is clarified. Five combinations here presented, namely Peperomia callitrichoide...

The antileishmanial and antimalarial activities of different fractions of Vincetoxicum stocksii, Carum copticum, Gentiana olivierii and Zygophyllum fabago were determined. Amongst these, V. stocksii and C. copticum showed moderate to good antimalarial activity. The ethyl acetate fractions of C. copticum and hexane fraction of V. stocksii showed 94 % and 52% inhibition of Plasmodium falciparum (...

One of the motor reactions commonly involved in the operation of both military and civilian equipment is that of moving a limb (or limbs) as quickly as possible from one position in space to another. Normally, it is desired to terminate the movement at exactly the aimed-for point with a minimum of error and oscillation. The aerial gunner, for example, in tracking a moving target, is often calle...

The alien invasive vine Vincetoxicum rossicum (Kleopow) Barbar. is problematic in the Lower Great Lakes Basin of North America. The lack of effective control strategies exacerbates the need for a better understanding of the growth and reproductive potential of V. rossicum. Thus, a 2-year field experiment was performed in a field site in 2003 and 2004 that was densely colonized by V. rossicum. M...
