Despite the current increase in studies on diet of neotropical anurans, few them take a comparative approach between syntopic species. The objective this study was to compare four species genus Physalaemus. collections occurred November 2014 and January 2016 preserved area subtropical Atlantic Forest southern Brazil. We compared gastrointestinal content 109 individuals distributed Physalaemus b...

Chrysichthys nigrodigitatus and C. auratus are important, highly valued and threatened freshwater species. To contribute with their ecological knowledge, the condition factor and diet of these two congeneric species were studied between April 2005 and April 2006. Food items of fish were evaluated by occurrence and numerical abundance methods, and the possible changes among sexes, seasons and si...

Overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA), was first defined by Flenley. Although it can refer to concomitant occurrence of any of the pulmonary diseases and OSA, overlap syndrome is commonly considered as the coexistence of OSA and COPD. This disease has unique adverse health consequences distinct from ...

Abstract The composition of the diet two species characids (Knodus heteresthes and Moenkhausia lepidura) was evaluated in Teles Pires Juruena Rivers, sampled September October 2016. We analyzed 226 stomachs K. 425 M. lepidura. analysis stomach contents based on volumetric frequency occurrence methods, applying food importance index. For similarity diets between we calculated niche overlap with ...

The widespread African clawed frog (Xenopus laevis) occurs in sympatry with the IUCN Endangered Cape platanna (Xenopus gilli) throughout its entire range in the south-western Cape, South Africa. In order to investigate aspects of the interspecific competition between populations of X. laevis and X. gilli, an assessment of their niche differentiation was conducted through a comprehensive study o...

Spatio-temporal changes in the diet, niche breadth and niche overlap of two species of Characidium from three different sites along a Neotropical coastal stream were studied during a dry and rainy season. Seasonal changes were restricted to the occurrence of plant items in the stomach contents. The relative importance of food items in the diet of both species varied across sites, but Diptera, E...

Abstract Introduction Diet selection of grazing livestock is one the critical factors affecting diversity and composition plant communities in grasslands, with consequent impacts for ecosystem functioning. Co‐grazing multiple species could create additive or complementary effects on due to diet overlap differentiation among species. However, there only limited knowledge about co‐occurring wheth...

The Mediterranean diet has been linked to a number of health benefits, including reduced mortality risk and lower incidence of cardiovascular disease. Definitions of the Mediterranean diet vary across some settings, and scores are increasingly being employed to define Mediterranean diet adherence in epidemiological studies. Some components of the Mediterranean diet overlap with other healthy di...

In the spring and summer of each year, large patches of submersed aquatic macrophytes overgrow the bottom of the alluvial Warta River downstream of a large dam reservoir owing to water management practices. Environmental variables, macroinvertebrates (zoobenthos and epiphytic fauna, zooplankton) and fish abundance and biomass were assessed at this biologically productive habitat to learn intras...
