The North American species Bidens frondosa L. ( Asteraceae) has been recorded as a new alien species for the flora of Turkey. The description of the species together with its drawing and distribution map is provided here.
- Two alien species of Bidens (Compositae), new to the flora of Serbia. Bogosavljević, Stefan S.; Zlatković, Bojan K. // Phytologia Balcanica;Aug2015, Vol. 21 Issue 2, p129
Two new alien species, Bidens subalternans and B. connatus, have been recorded in the flora of Serbia. While B. subalternans is recorded in ruderal areas, B. connatus can be found among the nitrophilous vegetation of the wet habitats in the urban and suburban parts of the town of NiÅ¡, in East...
- An intervention analysis of Hurricane Hugo's effect on South Carolina's stumpage prices Newman, David H.; Yin, Runsheng // Canadian Journal of Forest Research;Jun99, Vol. 29 Issue 6, p779
Using intervention analysis and Timber Mart-South price data, we test hypotheses concerning the impact of Hurricane Hugo on regional stumpage prices. In both the hardwood sawtimber and pine pulpwood markets, a gradual die-down price effect was detected, but a persistently higher or lower price...
- Modern pollen deposition in Long Island Sound Mecray, Ellen L.; Beuning, Kristina R. M.; ten Brink, Marylin R. Buchholtz; Nakityo, Berna; Fransen, Lindsey // Journal of Coastal Research;Summer2000, Vol. 16 Issue 3, p656
Palynological analyses of 20 surface sediment samples collected fromLong Island Sound show a pollen assemblage dominated by Carya, Betula, Pinus, Quercus, Tsuga, and Ambrosia, as is consistent with the regional vegetation. No trends in relative abundance of these pollen types occur either from...
- Impact of point source pollution on nitrogen isotope signatures (d15N) of vegetation in SE Brazil. Stewart, George R.; Aidar, Marcos P. M.; Joly, Carlos A.; Schmidt, Susanne // Oecologia;May2002, Vol. 131 Issue 3, p468
This study presents novel evidence that 15N natural abundance can be used as a robust indicator to detect pollutant nitrogen in natural plant communities. Vegetation from the heavily polluted industrial area of Cubatï¿½o in Sï¿½o Paulo State, SE Brazil, was strongly 15N depleted compared...
- Primary production and decomposition of wetlands of the Rhone Delta,France: interactive impacts of human modifications and relative sealevel rise Pont, Didier; Day, Jr., John W.; Ibanez, Carles // Journal of Coastal Research;Summer1999, Vol. 15 Issue 3, p717
Above ground primary production and above ground and below ground decomposition of several wetland species were studied in seven wetland sites in the Rhone delta from October 1992 to October 1993. The siteswere located in three characteristic zones of the delta: a low salinity area close to the...
- The biological flora of coastal dunes and wetlands. Ipomoea imperati (Vahl) Griseb. Lonard, Robert I.; Judd, Frank W. // Journal of Coastal Research;Summer1999, Vol. 15 Issue 3, p645
Beach morning glory, Ipomoea imperati (Vahl) Griseb. = I. stolonifera (Cirillo) Gmelin is a pantropical, prostrate vine that is an important pioneer species in the backshore of coastal beaches of six continents and many islands. The landward distribution of beach morning glory is influenced by...
