Tropical rainforests in Southeast Asia are facing increasing and ever more intense human disturbance that often negatively affects biodiversity. The aim of this study was to determine how tree species phylogenetic diversity is affected by traditional forest management types and to understand the change in community phylogenetic structure during succession. Four types of forests with different m...

largely owing to the labours of that veteran Sir Clements Markham (who only died a few days before these words were written), and of another Englishman, C. Ledger, in the j)eriod 1858-1865, and now, thanks to the foresight of a distinguished succession of Superintendents of the Botanic Gardens, the Government of Bengal have in the cinchona plantations at Mungpoo and Munsong a property of which ...

Restoration treatments are based on the largely untested notion that desired recovery of plant communities following disturbance wouldn’t occur in the absence of active intervention. We identified rate of short-term (10 year) floristic changes following removal of plant functional groups in Wyoming big sagebrush plant communities in 1999e2005 and 2008. Treatments imposed on 6 6 m plots were: 1)...

A large area of plantations has been established worldwide and especially in China. Evaluating the restoration status of these plantations is essential for their long-term management. Based on our previous work, we used an ecological memory (EM) approach to evaluate four 26-year-old plantations that represent four common kinds of plantations in subtropical China, i.e., mixed broad-leaved planta...

Parametric failures have been with us since the beginning of CMOS technology, but their significance is now more serious and growing. We refer to ac parametric timing failures that fall into two classes: (1) intrinsic ICs (free of defects), and (2) extrinsic ICs (presence of defects. The succession of 180 nm, 130 nm, and 90 nm CMOS IC technologies show an increasing lack of manufacturing contro...

A survey showed that species of Burkholderia were frequently associated with the roots of sugarcane. Based on amplified ribosomal DNA restriction analysis the isolates of these bacteria belonged to Burkholderia groups A,B,C,F and G. Data collected from field trials revealed a succession of species during the growth of the crop. Strains belonging to the B. cepacia complex were dominant during th...

The vegetation recovery at Kaimaumau gumland was monitored in seven permanent plots from 1988 to 1999 following a large fire in 1988 in order to determine rates and patterns of vegetation recovery. A succession profile for the key vegetation types that are currently developing is suggested. Schoenus brevifolius was the first species to colonise from rhizomes after the fire, and has remained the...

Low density plantings complemented by natural regeneration is an increasingly common reforestation technique to ensure growth of a sufficient number of trees from desired species while maintaining natural processes such as succession. One such form of low density planting that aims at lowering establishment costs—oak clusters—has been developed as an alternative to row planting since the 1980s ...
