Giant freshwater prawn (GFP) Macrobrachium rosenbergii is unique with males categorized in five different morphotypes (small claw, orange claw, blue claw, old blue claw and no claw males) and females in three reproductive statuses (mature ovary, berried and spawned females). In the present study we examined genetic inheritance of female and male morphotypes, their body weights and genetic assoc...

PURPOSE/OBJECTIVES To explore medical and psychosocial factors associated with body image dissatisfaction in male and female cancer survivors. DESIGN Secondary data analysis from the American Cancer Society's Study of Cancer Survivors-II pilot survey. SETTING Cancer survivors were identified through two state cancer registry databases. SAMPLE 165 male and 234 female cancer survivors of si...

This study investigates perceptions of gendered body ideals through an analysis of college students‟ drawings. A sample of 94 college students participated by drawing their image of the ideal female and male bodies. The drawings were analyzed through a gender lens, whereby each participant‟s male and female bodies were compared to determine the features participants used to indicate gender in t...

Body checking includes any behavior aimed at global or specific evaluations of appearance characteristics. Men and women are believed to express these behaviors differently, possibly reflecting different socialization. However, there has been no empirical test of the impact of gender on body checking. A total of 1024 male and female college students completed two measures of body checking, the ...

Given mixed findings regarding the unique trajectories of female and male adolescents' body dissatisfaction over time, comprehensive longitudinal examinations are needed. This 10-year longitudinal, population-based study, with 1902 participants from diverse ethnic/racial and socioeconomic backgrounds in the Minneapolis/St. Paul metropolitan area, examined changes in body dissatisfaction from ad...

ticks (acari: ixodidae) are obligatory blood feeders and important external parasites of wildlife, domestic animals and humans in tropical and subtropical areas. ticks primarily transmit different pathogenic organisms to livestock and humans, and secondly harm their animal hosts by decreasing blood protein content and nutrients due to partial exsanguinations, induce allergic reaction and someti...

OBJECTIVE To monitor the seasonal body composition alterations in 18 lightweight rowers (six females, 12 males) across a rowing season incorporating preseason, early competition, competition, and postseason. METHODS Subject age was 23.1 (SD 4.5) years, height 170.8 (5.6) cm (female, 23.5 (3.5) years, 180.5 (2.7) cm (male). Body weight, fat mass, and fat-free mass (FFM) were assessed using dua...

A trend for larger males to obtain a disproportionately high number of matings, as occurs in many animal populations, typically is attributed either to female choice or success in male-male rivalry; an alternative mechanism, that larger males are better able to coercively inseminate females, has received much less attention. For example, previous studies on garter snakes (Thamnophis sirtalis pa...

Males are generally expected to be discriminating in their choice of mates when females vary in quality and when under sperm competition from rival males. However, how sperm competition and female quality interact to influence male mating decisions remains poorly understood. Here, we explored the concurrent effects of sperm competition and female body length on male mating decisions in the Trin...
