An ontogenetic perspective on the relationship between age and size at maturity [PDF]
Functional Ecology, 2007 Summary Understanding the relationship between age and size at maturity is essential because these traits are pivotal determinants of an organism's fitness. The relationship between age and size is commonly addressed using optimization and quantitative genetic approaches. Here we argue that the value of such studies is often limited by an insufficient

Marine reserves and the evolutionary effects of fishing on size at maturation [PDF]
ICES Journal of Marine Science, 2009 Abstract Miethe, T., Dytham, C., Dieckmann, U., and Pitchford, J. W. 2010. Marine reserves and the evolutionary effects of fishing on size at maturation. – ICES Journal of Marine Science, 67: 412–425. Size-selective fishing may induce rapid evolutionary changes in life-history traits such as size at maturation.

Ontogenetic Basis of Among-Generation Differences in Size-Related Traits in a Polyphenic Butterfly
Frontiers in Ecology and Evolution, 2021 Seasonal polyphenisms are cases in which individuals representing generations occurring in different times of the year systematically differ in their morphological, physiological, and/or behavioral traits. Such differences are often assumed to constitute

Ciencias Marinas, 2011 Monthly samples of Pacific sierra Scomberomorus sierra were taken during nine years (1998–2000 and 2002–2007) with gillnets in Navidad Bay, Jalisco (Mexico). The sex ratio for the whole sampling period was not significantly different from 1 (F:M, 1:0.9).

SPO71 Mediates Prospore Membrane Size and Maturation in Saccharomyces cerevisiae [PDF]
Eukaryotic Cell, 2012 ABSTRACT The mechanisms that control the size and shape of membranes are not well understood, despite the importance of these structures in determining organelle and cell morphology. The prospore membrane, a double lipid bilayer that is synthesized de novo during sporulation in S. cerevisiae

Application of Size and Maturation Functions to Population Pharmacokinetic Modeling of Pediatric Patients [PDF]
Pharmaceutics, 2019 Traditionally, dosage for pediatric patients has been optimized using simple weight-scaled methods, but these methods do not always meet the requirements of children. To overcome this discrepancy, population pharmacokinetic (PK) modeling of size and maturation functions has been proposed.

Journal of Fisheries, 2016 Size at first maturity of Terapon jarbua was studied based on 114 male (14 to 28 cm in TL) and 140 female (14 to 32 cm in TL). The Logistic curves describing the relationship between the sexes and the proportion of 50% maturity (Lm50) were estimated at ...

Adaptive changes in harvested populations: plasticity and evolution of age and size at maturation
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004 We investigate harvest-induced adaptive changes in age and size at maturation by modelling both plastic variation and evolutionary trajectories. Harvesting mature individuals displaces the reaction norm for age and size at maturation toward older ages and larger sizes and rotates it clockwise, whereas harvesting immature individuals has the reverse ...

Evolutionary regime shifts in age and size at maturation of exploited fish stocks [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2006 Worldwide declines of fish stocks raise concerns about deleterious consequences of harvesting for stock abundances and individual life histories, and call for appropriate recovery strategies. Fishes in exploited stocks mature earlier at either larger or smaller sizes due to both genetic and plastic responses.
