As invasões biológicas contribuem de forma significativa para a perda biodiversidade global. Apesar do crescente número trabalhos sobre temática, ainda são necessários estudos que abordem distribuição dessas espécies. O objetivo deste estudo foi avaliar dispersão cinco espécies exóticas invasoras (Artocarpus heterophyllus, Crotalaria retusa, Leucaena leucocephala, Megathyrsus maximus e Prosopis...

Nitraria schoberi L. (Nitrariaceae) is a halophytic plant with continuous range in Central Asia and only two populations the westernmost distribution limit of species, Romania. Currently, there no documented explanation for species’ presence Europe, outside main area. Considering that marginal genetics are important establishing limits species adaptative potential, genetic diversity was assesse...

We first measured the δ(13)C and δ(15)N values of root holoparasite Cynomorium songaricum and its hosts from 19 sites across four provinces in northwest China, in an attempt to investigate their nutritional relationship at the Tibetan plateau and the surrounding Gobi desert. Our study showed that the δ(13)C of C. songaricum closely mirrored the values of its hosts, Nitraria tangutorum and N. si...

5,5'-Dihydroxy-2',4'-dimethoxy-7-[(6-O-β-d-apiofuranosyl-β-d-glucopyranosyl)-oxy]isoflavone (1) was isolated as the major constituent of Dalbergia vacciniifolia root bark ethanol extract together with the four known compounds 5,7-dihydroxy-2',4',5'-trimethoxyisoflavone (3), 5,7-dihydroxy-2',4'-dimethoxy-isoflavone (4), 5-hydroxy-2',4',7-trimethoxyisoflavone (5) and 7-hydroxy-2',4',5'-trimethoxy...

A successful attempt of using sodium salt of a water- insoluble larvicide, as an alternative to the use of solutions of such larvicides in acetone and water, for the larvicidal studies is made, in the present study biochanin - A an isoflavone isolated from the flowers of Dalbergia sissoides (grah) when assessed for larvicidal study as its sodium salt on the fourth instar larvae of Culex quinque...

Although cyclic electron flow (CEF) is essential for repair of PSII, it is unclear whether the CEF is stimulated and what the role of stability of PSI is during the recovery. In order to explore these two questions, mature leaves of Dalbergia odorifera were treated with the chilling temperature of 4°C under a photosynthetic flux density (PFD) of 650 μmol m(-2) s(-1) for 2 h and then were transf...
