Abstract Cambarus chasmodactylus is restricted to the New River drainage of the Central Appalachians. Female crayfish display cyclic reproductive states, but the ecological implications of this cycle have yet to be assessed. Female C. chasmodactylus were collected from Anthony Creek, West Virginia during the summer months to investigate food habits. Stomach content frequencies were obtained for four broad categories. Food items were identified to the lowest taxonomic level applicable. Feeding spectra were used to assess the importance of prey items. Generalized linear models were used to assess the effects of season, body size, and reproductive state on broad food categories, amount of food consumed, and the frequency of the most abundant prey item. The most food was consumed during June and the least in August. Organic detritus was consumed most frequently and reached its highest frequency in late summer. Animal matter was consumed more frequently by larger animals. Snails were the most predominate animal ingested, showing lower frequencies in June and September in comparison to August and October. Results indicate New River crayfish are feeding generalists and food habits changed with season. There is indication that body size and reproductive state may have a direct or indirect link to food habits.

Energy And Nutrient Intake

A study was conducted on the influence of maternal education level on food consumption, energy and nutrient intake, and dietary adequacy in 110 pre-school children from Madrid, Spain. With increasing maternal education, children consumed more sugar (p < 0.05), fruit (p < 0.05), and fish (p < 0.05). Snacking was more frequent with decreasing maternal education (p < 0.05). Though statistical significance was not reached, the consumption of pre-cooked foods was greater among children of mothers educated to a higher level, a phenomenon probably related to the work situation of these women. With respect to dietary composition, no significant differences were found between groups for macronutrient, fiber and energy intakes, except for energy supplied by polyunsaturated fatty acids (PUFA), which was greater in the children of less educated women (p < 0.01). This is probably due to their greater consumption of sunflower seed oil. The diets of children belonging to well-educated mothers came closer to meeting the recommended intakes for folate, vitamin C, and iodine. It would seem that maternal educational level influences the food habits of children. Mothers with less education may require special advice in this area.

Abstract. Emotion-related impulsivity, defined as the tendency to say or do things that one later regret during periods of heightened emotion, has been tied to a broad range of psychopathologies. Previous work has suggested that emotion-related impulsivity is tied to an impaired function of the serotonergic system. Central serotonin synthesis relies on the intake of the essential amino acid, tryptophan and its ability to pass through the blood brain barrier. Objective: The aim of this study was to determine the association between emotion-related impulsivity and tryptophan intake. Methods: Undergraduate participants (N = 25, 16 women, 9 men) completed a self-rated measure of impulsivity (Three Factor Impulsivity Index, TFI) and daily logs of their food intake and exercise. These data were coded using the software NutriNote to evaluate intakes of tryptophan, large neutral amino acids, vitamins B6/B12, and exercise. Results: Correlational analyses indicated that higher tryptophan intake was associated with significantly lower scores on two out of three subscales of the TFI, Pervasive Influence of Feelings scores r =  –.502, p < . 010, and (lack-of) Follow-Through scores, r =  –.407, p < . 050. Conclusion: Findings provide further evidence that emotion-related impulsivity is correlated to serotonergic indices, even when considering only food habits. It also suggests the need for more research on whether tryptophan supplements might be beneficial for impulsive persons suffering from a psychological disorder.
