orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. intensification is possible using dwarfing rootstocks that control tree size, induce early cropping and produce large quantities of fruit compared to the amount of wood produced. therefore, this study attempts to compare some yield and fruit properties of ...

This paper examines connectedness to, communication with and monitoring of unmarried adolescents in Ghana by parents, other adults, friends and key social institutions and the roles these groups play with respect to adolescent sexual activity. The paper draws on 2004 nationally-representative survey data and qualitative evidence from focus group discussions and in-depth interviews with adolesce...

this study was conducted to evaluate a temperature regime ranged from 15 to 30°c on survival, growth, life span and reproductive traits (reproductive period, clutch number, offspring number) of phallocryptus spinosa from iran. newly hatched nauplii (n= 200 and 3 replicates per each treatment) were allocated into containers and maintained at various temperature regimes (at 15, 20, 25 and 30˚c). ...

The effect of nest aggregation in courtship behaviour was tested experimentally in an ecologically constrained, sex-role reversed population of the peacock blenny Salaria pavo. Mixed sex groups of eight males and eight females were tested in experimental tanks, containing eight potential nests either aggregated or dispersed. In the aggregated treatment, males spent more time inside their nests ...

Gender differences in South African men and women's access to and evaluation of informal sources of sexual and reproductive health (SRH) information Erin Stern, Diane Cooper & Andrew Gibbs a Women's Health Research Unit, School of Public Health, University of Cape Town, Cape Town, South Africa b HEARD (Health Economics and HIV/AIDS Research Division), University of KwaZulu-Natal, Durban, South ...

The Haemulon plumieri is a typical reef-associated and tropical species found in warm and temperate waters of the Western Atlantic. Due to the large fishing effort directed to H. plumieri, the knowledge about its reproductive biology is essential for correct stock management and conservation. The aim of this study was to characterise reproductive biology with a focus on its seasonal variation o...

BACKGROUND This study evaluated the quality of life and anxiety-depression levels of patients prior to receiving assisted reproductive techniques. MATERIALS AND METHODS This cross-sectional research was conducted in the In-Vitro Fertilization Unit of a private University's Faculty of Medicine, Department of Obstetrics and Gynecology. Study participants consisted of 160 individuals diagnosed a...

Currently, less than 10% of current global funding for research is spent on diseases that afflict more than 90% of the population. This is referred to as the 10/90 gap in health research, and efforts to close it are mounting as part of the wider equity agenda in health. Increasingly it is being recognized that gender issues must be central to these efforts, since women comprise the majority of ...

Theory predicts that sexual (or behavioral) isolation will be the first form of reproductive isolation to evolve in lineages characterized by sexual selection. Here I directly compare the rate of evolution of sexual isolation with that of hybrid inviability in a diverse and sexually dimorphic genus of freshwater fish. The magnitude of both sexual isolation and hybrid inviability were quantified...
