Woody vegetation encroachment in natural grasslands is a concern in many parts of the world. We evaluated the effect of Baccharis uncinella (Asteraceae) encroachment on grassland vegetation in southern Brazil, in terms of plant composition and richness. We conducted a vegetation survey in 12 plots of 10 × 10 m. The study site was a forest-grassland mosaic where management practices have been ex...

Let F be a hypergraph and let forb(m,F ) denote the maximum number of edges a hypergraph with m vertices can have if it doesn’t contain F as a subhypergraph. A conjecture of Anstee and Sali predicts the asymptotic behaviour of forb(m,F ) for fixed F . In this paper we prove that even finding this predicted asymptotic behaviour is an NP-hard problem, meaning that if the Anstee-Sali conjecture we...

Abstract Long-term active restoration is often employed to restore degraded grasslands. The establishment of a viable soil seed bank the key successful restoration, as it enhances resilience vegetation. However, little known how affects vegetation following long-term We determined abundance and species composition properties intact, degraded, (>10 years) actively restored grasslands on Tibet...

The desirable structure of longleaf pine forests, which generally includes a relatively open canopy of pines, very few woody stems in the mid-story, and a well-developed, herbaceous ground layer, provides critical habitat for flora and fauna and contributes to ecosystem function. Current efforts to restore longleaf pine to upland sites dominated by second-growth loblolly pine require informatio...

Relationships between soil factors and vegetation types in playa of Damghan was investigated. Six vegetationtypes including Artemisia.sieberi, Arundo. sp, Artemisia.sieberi-Peganum.harmala, Alhagi.cammelerom,Artemisia.sieberi-petropyron.sp, Tamarix.passerinoides-Halocnemum strobilaceum. One bare land was recognized inthe study area and the research was conducted within mentioned types. Canopy p...
