Geological control of floristic composition in Amazonian forests

AIM: Conservation and land-use planning require accurate maps of patterns in species composition and an understanding of the factors that control them. Substantial doubt exists, however, about the existence and determinants of large-area floristic divisions in Amazonia. Here we ask whether Amazonian forests are partitioned into broad-scale floristic units on the basis of geological formations a...

Guruswami-Sinop Rounding without Higher Level Lasserre

Guruswami and Sinop [11] give a O(1/δ) approximation guarantee for the non-uniform Sparsest Cut problem by solving O(r)-level Lasserre semidefinite constraints, provided that the generalized eigenvalues of the Laplacians of the cost and demand graphs satisfy a certain spectral condition, namely, λr+1 ≥ Φ∗/(1 − δ). Their key idea is a rounding technique that first maps a vector-valued solution t...

weed floristic composition in lentil (lens culinaris) farms in khorramabad

studies on floristic composition of weeds in an agricultural zone could help to reach a better weed control management strategies. the goal of this article was the study of the floristic composition of lentil weeds grown filds in khorramabad, during 2007-2008. sampling was done on 9 point of each field according to w method in 21farm. in each plat per plate of all weed species were counted sepa...

Floristic Structure and Vegetation Composition of Boralan Mountainous Rangelands in North-Western Azerbaijan, Iran

Recognition of habitats and conditions of species presences in differentsituations can be effective in proper utilization of vegetation. Little is known about thevegetation composition of Boralan Mountain region located in North West of Iran in theborder of Turkey and Azerbaijan with the altitude range of 800-2000m. The aim of thisstudy therefore was to investigate the floristic composition qua...
