Knowing the interactions between exotic and native species is essential to establish possible threats local fauna. In this study, we assessed use of food resources diet overlap a recently introduced snail, Sinotaia quadrata, species, Pomacea canaliculata. We analyzed gut content stable isotope snails in lowland stream where both coexist. Both Schoener’s dietary indexes supported overlap. Conver...
We compared sources of variability and cost in paired stomach content and stable isotope samples from three salmonid species collected in September 2001–2005 and describe the relative information provided by each method in terms of measuring diet overlap and food web study design. Based on diet analyses, diet overlap among brown trout, rainbow trout, and mountain whitefish was high, and we obse...
Abstract Ontogenetic shifts in food preference reduces intraspecific competition as immature individuals eat different types than adults. This diet plasticity could facilitate species’ ability to successfully invade and establish itself a new environment, even when co-occurring with phylogenetically close species. Here, ontogenetic of non-native piranha species (Serrasalmus marginatus) was test...
While lifestyle management is recommended as first-line treatment of polycystic ovary syndrome (PCOS), the optimal dietary composition is unclear. The aim of this study was to compare the effect of different diet compositions on anthropometric, reproductive, metabolic, and psychological outcomes in PCOS.

OBJECTIVE To verify the effects of an intervention program including physical exercise and recreational activities, as well as nutritional counseling, on the health-related quality of life of obese children. METHODS This was a controlled clinical trial. The initial study population included children aged eight to 11 years with a body mass index (BMI) > 97th percentile for age and gender, acco...
OBJECTIVE We examined parental and early-life variables in order to identify risk factors for adulthood overweight and obesity in offspring. We report here on the longitudinal prevalence of overweight and obesity in Australian children born between 1989 and 1991 and followed from birth to age 22. METHODS Data were analysed on 1355 participants from the Western Australian Pregnancy Cohort (Rai...
The United Nations Global Agenda for Sustainable Development, particularly through Goal 2, simultaneously seeks to end hunger, achieve food security, improve nutrition and promote sustainable agriculture. Therefore, it is crucial focus on the agricultural production system consumption conditions. This means that ‘access’ should be determined with respect three dimensions of economic, physical s...
The authors compared how four indexes-the Healthy Eating Index-2005, Alternate Healthy Eating Index, Mediterranean Diet Score, and Recommended Food Score-are associated with colorectal cancer in the National Institutes of Health-AARP Diet and Health Study (n = 492,382). To calculate each score, they merged data from a 124-item food frequency questionnaire completed at study entry (1995-1996) wi...
