Abstract Fimbristylis genus had commonly found as a dominant weed in the rice fields. The sedges have been identified one of invasive world and their undesirable presence disturb growth crop. secondary metabolites, on other hand, revealed that this plant is capable wide range biological activities. Therefore, study focused phytochemistry, antioxidant antifungal properties 2 weeds Fimbristylis. ...

Plant traits mirror both evolutionary and environmental filtering process with universal trait-trait relationships across plant groups. However, plants also develop unique precisely to different habitats, inducing deviations of the trait coupling relations. In this study, we aimed compare differences in leaf examine generality shifts between alpine aquatic terrestrial herbaceous on Tibetan Plat...

Eriophyoid mites (Acariformes, Eriophyoidea) are microscopic chelicerates morphologically greatly preadapted to endoparasitism on plants. Members of at least six phylogenetically distant eriophyoid genera from two families homoplastically transitioned and acquired the ability penetrate under plant epidermis feed parenchymatous cells, usually causing necrosis. Theoretically, endoparasites expect...

Fire is inextricably linked to the vegetation that provides fuel load. For palaeofire records contribute meaningfully reconstruction of past landscape fire history, it helpful identify has been burnt, for example, grassy versus woody in tropical savannas. The morphological characteristics charcoal particles can provide useful information on source type, and aspect ratio proposed contribution gr...

Hassan, H. M., Jiang, Z.-H., Syed, T. A. and Qin, W. 2012. Review: Northern Ontario medicinal plants. Can. J. Plant Sci. 92: 815 828. The majority of scholarly investigations conducted in the 20th century have provided the incentive for establishing plants as sources of diverse phytochemicals. With infectious and cancerous diseases causing millions of mortalities worldwide, and the advent of re...

[1] Net ecosystem CO2 exchange (NEE) was measured from June 2000 through October 2001 by 10 automatic chambers at a peatland in southeastern New Hampshire. The high temporal frequency of this sampling method permitted detailed examination of NEE as it varied daily and seasonally. Summer of 2001 was significantly drier than the 30-year average, while summer of 2000 was wetter than normal. Althou...

Oziella sibirica sp. nov., collected from sedges (Cyperaceae: Carex macroura) in Siberia, Russia, is herein described based on the external morphology of all active instars using primarily conventional phase contrast microscopy, and on the female internal genitalia and prodorsal shield design using confocal laser scanning microscopy (CLSM) imaging and a 3D modelling technique. A partial mitocho...

Topography is an important factor in determining vegetation patterns in grasslands. We collected frequency of occurrence data from transects on dune tops, south-facing slopes, north-facing slopes, and interdunal valleys in the eastern Sandhills of Nebraska to determine the effect of topographical position on plant species composition. We used canonical discriminant analysis to separate the four...

Regional genetic differentiation within species is often addressed in evolutionary ecology and conservation biology. Here, we address regional differentiation in two closely related hybridizing taxa, the perennial sedges Carex flava and C. viridula and their hybrid C. × subviridula in 37 populations in the north and centre of their distribution range in Europe (Estonia, Lowland (<1000 m a.s.l.)...

—Little information exists on breeding Greater Sandhill Cranes (Grus canadensis tabida) in riparian wetlands of the Intermountain West. We examined the nesting ecology of Sandhill Cranes associated with riparian and palustrine wetlands in the Henry’s Fork Watershed in eastern Idaho in 2003. We located 36 active crane nests, 19 in riparian wetlands and 17 in palustrine wetlands. Nesting sites we...
