Spoor counts as indices of large carnivore populations: the relationship between spoor frequency., sampling effort and true density

1. Studies of large carnivore populations and, particularly, reliable estimates ofpopulation density are necessary for effective conservation management. However, these animals are difficult to study, and direct methods of assessing population size and density are often expensive and time-consuming. 2. Indirect sampling, by counting spoor, could provide repeatable and inexpensive measures of so...

Achieving per-flow Queueing Performance without a per-flow Queue

Recent studies have shown that suitably-designed packet discard policies can dramatically improve the performance of fair queueing mechanisms in internet routers. The Queue State Deficit Round Robin algorithm (QSDRR) preferentially discards from long queues, but introduces hysteresis into the discard policy to minimize synchronization among TCP flows. QSDRR provides higher throughput and much b...
