Even with all of the stresses that come with a new cancer diagnosis, such as understanding the chances of survival, impending treatments, fi nancial burdens, and familial and work obligations, many young people diagnosed with cancer have signi fi cant concerns about their future fertility. In fact, among young women with cancer, concerns about children and family are second only to fears of can...

the effect of eight cucumis l. (cucurbitaceae) genotypes, including native cucumber genotypes (hormozgan, bushehr and gilan), greenhouse cucumber genotypes (girtap, negeen, sepehr and pouya) and armenian cucumber (cucumis melo var. flexuosus) was studied on the life table and population growth parameters of aphis gossypii glover to evaluate antibiosis resistance. the experiment was conducted at...

Teenage mothers and their children face poorer prospects in life than do women who delay motherhood until later in life. Moreover, patterns of early childbearing tend to be repeated in subsequent generations. Therefore, an understanding of the factors associated with early fertility is important for the prevention of adverse consequences. This paper uses data from the National Survey of Sexual ...

the effect of various host plants including chickpea (varieties arman, hashem, azad and binivich), common bean (variety khomein), white kidney bean (variety dehghan), red kidney bean (variety goli), cowpea (variety mashhad), and tomato (variety meshkin) on the reproductive performance and growth indices of the cotton bollworm, helicoverpa armigera (hübner) was determined under laboratory condit...

This study compared two methods, based on re-analyzed data from a partly published life table response experiment (LTRE), to help determine the optimal approach for designing ecotoxicological assessments. The 36-day LTRE data recorded the toxic effects of cadmium (Cd) and imidacloprid, alone and in combination, on the reproduction and survivorship of aphids (Acyrthosiphon pisum Harris). We used...

Background Humans life histories have been described as “slow”, patterned by slow growth, delayed maturity, and long span. While it is known that human history diverged from of a recent common chimpanzee-human ancestor some ~4–8 mya, unclear how selection pressures led to these distinct traits. To provide insight, we compare wild chimpanzees subsistence societies in order identify the age-speci...

This paper examines the relationships between satisfaction with life in general, particular domains of life, the partner, and parental relationships with existing children, and subsequent fertility. The data are from 2,948 women and 2,622 men aged 15 to 44 years, from a longitudinal survey of the household population in Australia. For both sexes, a strong positive relationship between prior sat...

The effects of natural or experimental environmental perturbations on populations can be diverse, simultaneously affecting several life history variables. Populationlevel responses to such influences frequently are measured as changes in projected population growth rate (l). Sensitivity and elasticity analyses can be used to quantify the potential influence of small changes in different life hi...
