Integrodifference equations, Allee effects, and invasions   总被引:4,自引:0,他引:4  
 Models that describe the spread of invading organisms often assume no Allee effect. In contrast, abundant observational data provide evidence for Allee effects. We study an invasion model based on an integrodifference equation with an Allee effect. We derive a general result for the sign of the speed of invasion. We then examine a special, linear–constant, Allee function and introduce a numerical scheme that allows us to estimate the speed of traveling wave solutions.

To understand its unprecedented resurgence, we examined the epidemiological, virological, and entomological features of dengue in Guangzhou during 1978-2009. Cases reported to the Guangzhou Centre for Disease Control and Prevention and data from virological and entomological surveillance were analyzed from three periods: 1978-1988, 1989-1999, and 2000-2009. Although cases decreased over time: 6,649 (1978-1988) to 6,479 (1989-1999) to 2,526 (2000-2009), geographical expansion resulted in districts with an average incidence >2.5/100,000, increasing from five (1978-1988, 1989-1999) to seven (2000-2009). Age distribution (mean age: 34.9 years) provided a trend of increasing dengue incidence among adults, and there was a significantly higher incidence among men with a sex ratio of 1.15:1 (P<0.001). Cases occurred from May through November with a peak between August and October, and a long-term trend was characterized by a three to five-year cyclical pattern. The most frequently isolated serotypes were DENV-2 (1978-1988) and DENV-1 (1989-1999 and 2000-2009). Seasonal fluctuations in immature densities of Aedes albopictus (sole transmission vector in Guangzhou) were consistent with the dengue seasonality. After a 30-year apparent absence, DENV-3 had reemerged in 2009. The current epidemiological situation is highly conducive to periodic dengue resurgences. Thus, a high degree of surveillance and strict control measures in source reduction should be maintained.  相似文献

The gene encoding pyrrolidone carboxyl peptidase (Pcp) has been cloned from the hyperthermophilic archaeon Thermococcus litoralis. The recombinant enzyme has been expressed in Escherichia coli, purified, and char-acterized. The T. litoralis Pcp demonstrates strong sequence homology to previously characterized bacterial Pcps. Some investigations have been carried out on enzyme substrate specificity and stability. Received: July 4, 2000 / Accepted: July 21, 2000  相似文献

A new mullid fish, Parupeneus procerigena, is described on the basis of 13 specimens (118.9–198.4 mm SL) from depths of 92–148 m off the Saya de Malha Bank in the western Indian Ocean. This species resembles P. chrysopleuron and P. heptacanthus in color pattern without black stripes or spots, but it differs from them in having more gill rakers, two scales in lachrymal region, deeper body, deeper cheek, and longer distance between nostrils.
