This talk consists of two parts. In the first, the present experimental bounds on the anomalous couplings of the gauge bosons, based mainly on the LEP and Tevatron experiments, are reviewed. In the second part, the theorem of helicity conservation (HC) is presented, which should be valid in either the Standard Model (SM) or MSSM, for any two-body process at high energies and fixed angles. The e...

1. The conservation of insects is not a priority for most urban dwellers, yet can be accomplished in urban settings by the careful design of urban nature. Our goal is to foster cross-talk between practitioners of insect conservation biology who develop the knowledge base and professional design practitioners who are poised to apply this knowledge in designs and management plans for urban green ...

Population viability of the giant panda ( Ailuropoda melanoleuca ) is threatened by small population sizes in scattered isolated habitat areas. Designing a conservation plan for protecting and connecting the fragmented habitat will improve the chances for survival of this endangered species. For such a plan, this study assessed the overall habitat suitability for the species in the Qionglai mou...

The conservation status of Convolvulus scindicus Stocks in Pakistan, was assessed according to IUCN red data categories and criteria. After three years (2006-2008) of extensive field studies based on population size, distribution range, nature of habitat and anthropogenic activities, the conservation status of Convolvulus scindicus has been classified as an endangered (EN) species. Conservation...

The object of the present lecture is the discussion of the group-theoretical nature of the conservation theorems for differential equations. To illustrate the use of the general conservation theorems the differential equations of mechanics are chosen.

(To appear as a chapter in " Research priorities for nature conservation " in 2001 – a book sponsored by the Society for Conservation Biology and edited by Soule, Orians and Kohm)
