thibbitts@tamu.edu / I investigated three mechanisms (endurance rivalry, contest competition, and mate choice) of sexual selection and the influence of multiple signals on intrasexual and intersexual encounters in the common barking gecko (Ptenopus garrulus). Aspects of the ecology of barking geckos were also studied to facilitate the investigation of sexual selection. Barking geckos exhibited sexual size dimorphism in relation to head size, with males having wider heads. No differences in diet or size of prey ingested were observed between the sexes, indicating that niche divergence was not occurring. Therefore, the difference in head width was best explained by sexual selection (male contest competition). Barking gecko diet was dominated by termites by number and volume. The peak reproductive season was in October for both sexes.
I used activity patterns to determine if males emerged before females from winter dormancy, a key assumption of the protandry-based mating system model. Activity patterns were significantly different between males and females. Males were active in higher numbers early in the breeding season. Male and female activity patterns along with evidence that male territories were established before female emergence, testicular recrudescence likely coincides with male emergence, and larger males have larger territories and better reproductive success, suggest that barking geckos have a protandry-based polygynous mating system. I also tested for clustering of geckos on the landscape to determine if barking geckos lek. Clustering was found to occur in some instances, but barking geckos did not

meet the criteria for a ‘classical’ lek species because males use calling sites containing resources (a burrow) that are also used by females.
Lizards frequently rely on chemical cues to detect the presence of a conspecific. Male lizards in particular, may chemically sample potential refuges to avoid rivals. Barking geckos were equally likely to use an artificial refuge scented by another male compared to a control, indicating that males do not use scent when selecting refuges.
I assessed the role of two signals, one acoustic (dominant call frequency) and one visual (yellow throat patch), in advertising residency and aggressive behavior in barking geckos. Larger males defended the largest home ranges and home ranges were maintained through calling, which is negatively correlated with body size. Body size also predicted some behavioural responses to field-playback trials. Small males retreated from the playback and large males were found to be aggressive towards the playback. Small relative throat patch size was also correlated with aggression and charging the playback. Finally, call frequency was correlated with the behaviour of charging the playback. I suggest that the frequencies of barking gecko calls constitute a long-range signal of body size, used by males for remote rival assessment and to advertise home range boundaries.
I also assessed the role of multiple signals (acoustic and visual) in reproductive success and I studied the effect of one mechanism of sexual selection, endurance

rivalry, on reproductive success. Activity levels were similar for males which bred compared to those that did not breed, suggesting that endurance rivalry is not a significant mechanism of sexual selection in this population. Body size was the best predictor of reproductive success, suggesting that call frequency functions as a long range signal of body size used by females to assess potential mates.

The influence of single nucleotide polymorphisms in taste receptor gene TAS2R38 on eating behavior and body compositionSaddam, Ahmed Chaloob 03 May 2019 (has links)
Taste impacts the palatability and intake of food, which is influenced by several factors such as cultural and genetic factors. Individual variations in taste perception may be important risk factors for poor eating habits and development of obesity. The differences in taste perception which impact dietary intake may lead to better understanding of obesity development and prevention of diet-related diseases. Obesity is one of the main causes for various health conditions in the United States as well as in the world. Genetic inheritance plays an important role in individual variations to taste and food choices. This study explored associations between two single nucleotide polymorphisms (SNPs, rs713598 and rs10246939) in the TAS2R38 bitter taste receptor gene, dietary intake, and body fat percentage. Five hundred presumably healthy students aged 18-25 years, including 86 (17%) males and 414 (83%) females from Mississippi State University participated in the study. Saliva was collected for genetic analysis, participants completed dietary history questionnaires and body composition was measured using bioelectrical impedance analysis. All statistical analysis of data was conducted using SPSS software to examine associations between SNPs, food intake, and percentage of body fat. Our results did not show a significant association between the SNPs; rs713598 and rs10246939 in the TAS2R38 bitter taste receptor gene and dietary intake of vegetables and fruits as well as percentage of body fat in this group of participants. However, alcohol and caffeine intakes were significantly different between genotypes in rs713598; p< 0.01, p< 0.05, respectively.

Elevers attityder till hälsa och kost relaterat till skolprestationHolmgren, Johanna January 2009 (has links)
Detta examensarbete behandlar huruvida elevers attityder till hälsa och kost är relaterat till deras attityd om skolprestation. Eleverna som deltog i undersökningen gick på en skola i en förort till Malmö och arbetade under tre veckor med ett hälso-tema som behandlade kost, motion och välbefinnande. Mina frågeställningar lyder:•Hur ser elevernas fysiska aktivitet ut?•Hur ser elevernas matvanor ut?•Hur ser eleverna själva på sina skolprestationer och prestationer i övrigt?•Har temaveckorna ändrat elevernas syn på någon av punkterna ovan?Jag har med hjälp av ovanstående frågor försökt se om fysisk aktivitet har någon koppling till hur eleverna ser på sina skolprestationer och sitt kostval. Min undersökningsmetod var enkäter som kompletterades med enskilda samtal angående enkätfrågorna. Enkätsvaren visade att 78 % av eleverna hade fysiska aktiviteter efter skoltid och att dessa elever fann det viktigt att prestera så bra som möjligt i skolan med undantag av en elev. Eleverna var ganska noga med vad de åt men mest var det föräldrarna som bestämde dieten. Samtliga elever uppgav att de var mer medvetna efter temaveckorna om sin diet och sin fysiska aktivitet.

Haitian American Mothers' Health And Dietary Beliefs Concerning Their InfantsSchooler, Daniel 01 January 2008 (has links)
Studies on the effects of immigration are becoming more important as the number of immigrants into the United States continues to grow. This study was implemented in order to discover the infant feeding practices and beliefs of Haitians living in Central Florida. A food frequency card sort and interview were conducted with thirty-four Haitian mothers. Mothers were asked to identify which foods they fed their children. Foods pictured on the cards included a majority of Haitian staple foods, some of which are primary to the American diet as well. Low food feeding frequencies were generally attributed to lack of access to foods or lack of funds. Inexpensive foods, such as rice and beans, which are staples to the Haitian diet, remain prevalent in infant feeding among Haitians living in the United States. However, more American starches like potatoes and cereals are replacing other Haitian staples, such as yams and yuca. This study suggests that dietary acculturation among Haitian Americans is occurring, but not rapidly in this population. Furthermore, women did not express a strong relationship between beliefs about particular foods and infant health.
