THE EFFECTS OF PREDATION ON THE AGE AND SIZE OF MATURITY OF PREY [PDF]
Evolution; International Journal of Organic Evolution, 1996 The effects of nonselective predation on the optimal age and size of maturity of their prey are investigated using mathematical models of a simple life history with juvenile and adult stages. Fitness is measured by the product of survival to the adult stage and expected adult reproduction, which is usually an increasing function of size at maturity ...

Size at maturity of Mediterranean marine fishes
Reviews in Fish Biology and Fisheries, 2013In this review we collected data on the length at maturity (Lm) and maximum reported total length (Lmax) of 565 Mediterranean marine fish stocks, representing 150 species, 68 families, 24 orders and 3 classes. Overall, Lm ranged from 2 cm, for the males of the toothcarp Aphanius fasciatus, to 350 cm, for the females of the bluntnose sixgill shark ...

Relationship between genome size and maturity group in soybean
Theoretical and Applied Genetics, 1994Previous studies have reported a correlation between genome size and relative maturity among plant species. The objective of this study was to determine whether such a relationship exists in soybean. Twenty cultivars, representing maturity groups ranging from 000 to IX, were analyzed using flow cytometric procedures. A 15% difference in genome size was

Age and size at maturity in women: A norm of reaction?
American Journal of Human Biology, 2010AbstractObjectives:We present the first review and meta‐analysis of the association between adult stature and age at menarche over a broad range of human societies. We then outline possible biological explanations for observed empirical associations.Methods:We analyzed the association between adult stature and age at menarche in 141 samples from ...

Mechanism-Based Concepts of Size and Maturity in Pharmacokinetics
Annual Review of Pharmacology and Toxicology, 2008Growth and development can be investigated using readily observable demographic factors such as weight and age. Size is the primary covariate and can be referenced to a 70-kg person with allometry using a coefficient of 0.75 for clearance and 1 for volume. The use of these coefficients is supported by fractal geometric concepts and

Fitness and body size in mature odonates
Ecological Entomology, 2000Summary The relationship between body size and fitness components in odonates was examined using a meta‐analysis of 33 published studies. There was a positive and significant overall effect of body size on mating rate and lifetime mating success among males. There was also a weaker but still significant positive effect of body size on

Optimal Size at Maturity in Size-Structured Populations
Journal of Theoretical Biology, 1997Abstract Maturity is a critical point in the life cycle, and determining the optimal age or size at maturity is a classical problem in life history theory. Most organisms spend some time in non-reproductive immature stage. To explain the widespread occurrence of delayed maturity, a number of authors made mathematical models with the age-specific ...

Flathead Catfish Age and Size at Maturation in Texas
North American Journal of Fisheries Management, 1994Abstract One hundred ninety-nine flathead catfish Pylodictis olivaris, ranging in total length from 290 to 999 mm, were collected from 31 Texas reservoirs to determine the relationship between size and age at sexual maturation. Logistic regression indicated that length, age, and geographic location of capture were significantly related to sexual ...

Genome size and maturity group in Glycine max (soybean) [PDF]
Heredity, 1997 Recent literature data indicate a 1.15-fold difference in genome size between certain cultivars of soybean and a positive correlation of genome size and maturity group. The present analysis aims at a reinvestigation of these cultivars using DAPI and ethidium bromide flow cytometry and Feulgen densitometry.
