Life history traits of wild animals can be strongly influenced, both phenotypically and evolutionarily, by hunting and fishing. However, few studies have quantified fishery selection over long time periods. We used 57 years of catch and escapement data to document the magnitude of and trends in gillnet selection on age and size at maturity of a commercially and biologically important sockeye sa...

OBJECTIVES We test (McIntyre and Kacerosky's [2011]: Am J Hum Biol 23:305-312) prediction that the relationship between age at menarche and height switches from negative to positive, in a unidirectional and smooth manner, as the society industrializes. According to this prediction, a mid-level industrial country should exhibit a weak relationship between the two variables. METHODS The 8,013 o...

This is the first-ever study conducted to standardize the maturity stage of olive fruit for development of olive murabba. Olive fruit was harvested at three different maturity stages including lemon green, semi-ripened and fully ripened stages for postharvest processing. Most prominent quality parameters of the product were studied for all maturity stages. Olive productprepared from semi-ripene...

Length-weight relationship, length at first maturity and sex ratio of the Nile perch Lates niloticus (L.) were studied from 342 fish samples collected between February 1995 and May 1996. The relationship between total length (TL) and total weight (TW) for both sexes was curvilinear and statistically significant. The regression equation for the males was TW=0.0044TL3.27 (r2=0.978, P<0.001) and t...

Many organizations have recognized the importance of increasing commitment towards delivering longterm success of Business Intelligence (BI). However, effective BI strategies and governance to accommodate the rapid growth of data volumes are still scarce. Furthermore, there appears to be low usage rates of BI and analytics among business users. Consequently, many organizations are still positio...

The present study explores the relationship between the e-business maturity and the perceived benefits from (Information and Communication Technologies) ICT at the firm level. We aim to debunk this relationship in terms of its strength and stability, and to explore the conditions which may influence it. Taking an economic approach, we hypothesise that the relation between e-business maturity an...

—Size at maturity is incorporated into stock assessments of walleye pollock Theragra chalcogramma. For eastern Bering Sea walleye pollock, however, this important biological variable has not been examined since 1976 and possible interannual and geographic variations have never been evaluated. Maturity condition and fish length data were collected from 10,197 walleye pollock aboard factory trawl...

For fish stocks managed using biological reference points based upon spawning biomass, it is critical to have accurate maturity schedules. We investigated sizeand age-dependent patterns in maturity for southern flounder Paralichthys lethostigma, a flatfish supporting valuable coastal fisheries in North Carolina and throughout its range. We evaluated both macroscopic and histological methods ove...

Ratios of effective populations size, N(e), to census population size, N, are used as a measure of genetic drift in populations. Several life-history parameters have been shown to affect these ratios, including mating system and age at sexual maturation. Using a stochastic matrix model, we examine how different levels of persistent individual differences in mating success among males may affect...
