Size at maturity, fecundity, and reproductive periodicity were estimated for the spotted ratWsh, Hydrolagus colliei (Lay and Bennett, 1839), oV the coast of California, Oregon, and Washington. Maximum body size and size at median maturity were greater for females than males. Skeletal muscle concentrations of the steroid hormones testosterone (T) and estradiol (E2) predicted similar, but slightl...
In the past decade, there has been a new effort to understand the ecology that drives population divergence and speciation. It is well established in theory that speciation is most likely to occur when a trait that is under divergent natural selection in different populations is also used in mate choice. Such traits have been dubbed ‘magic traits’ (Gavrilets, 2004) and, although there appears t...
Intensive size-selective harvesting can drive evolution of sexual maturity at smaller body size. Conversely, prehistoric, low-intensity subsistence harvesting is not considered an effective agent of size-selective evolution. Uniting archaeological, palaeontological and contemporary material, we show that size at sexual maturity in the edible conch Strombus pugilis declined significantly from pr...
The development of e-Government at the local level is becoming the subject of interest of many researchers. The prevailing opinion is that eGovernment is developing as an evolutionary model and while evaluating the status and maturity of the eGovernment the e-Government Maturity Model (eGMM) is in use. During 2009, a survey of maturity of the towns' Web sites in Croatia was conducted. According...
