1. Despite the routine nature of studying home-range (HR) overlap, a formal inferential framework for overlap analyses has only recently emerged. This allows computation approximate confidence intervals (CIs) Bhattacharyya coefficient (BC), pairwise metric with basis in distributional similarity. However, prior comparisons common metrics suggest that utilization distribution index (UDOI) is pre...

The Barents Sea system is often depicted as a simple food web in terms of number of dominant feeding links. The most conspicuous feeding link is between the Northeast Arctic cod Gadus morhua, the world's largest cod stock which is presently at a historical high level, and capelin Mallotus villosus. The system also holds diverse seabird and marine mammal communities. Previous diet studies may su...

We analyzed the stomach contents of 116 individuals belonging to seven fishes species in order to investigate seasonal changes in feeding strategy and how trophic interactions between species affect community structure in an Atlantic rainforest stream in Southeastern Brazil. Oligosarcus hepsetus and Pimelodus sp. consumed fewer items during the winter. Phalloceros caudimaculatus switched feedin...

Suitable habitats for anurans can be found in the ever-growing tropical urban environments but anurans' adaptations to conditions, including their trophic ecology remain largely unknown. We studied food habits of two generalist, widespread West African Sclerophrys adult toads: common (Sclerophrys regularis) and Hallowell's toad maculata). The first was Lomé (Togo), Cotonou (Benin) Ikeja (Nigeri...

Introduction: Chronic obstructive pulmonary disease (COPD) patients are at increased risk of sleep-disorders. The concomitant occurrence of COPD and obstructive sleep apnea hypopnea syndrome (OSAHS) is named overlap syndrome. This study aimed to evaluate the severity of OSAHS in overlap syndrome patients.Materials & Methods: This cross-sectional study was conducted on adult patients with forced...

Adaptive radiation can be strongly influenced by interspecific competition for resources, which can lead to diverse outcomes ranging from competitive exclusion to character displacement. In each case, sympatric species are expected to evolve into distinct ecological niches, such as different food types, yet this expectation is not always met when such species are examined in nature. The most co...
