Abstract Diet-based annual biomass indices can potentially use predator stomach contents to provide information about prey and may be particularly useful for species that are otherwise poorly sampled, including ecologically important forage fishes. However, diet-based sensitive underlying ecological dynamics between predators prey, such as functional responses changes in overlap space time. To ...

To understand how contractions move gastric contents, we measured, in isolated cat stomachs, the effects of contractions on gastric length, diameters, pressures, and emptying. Movements of the stomach and of gastric contents were monitored by video camera and ultrasound and were related to mechanical events. Based on pressures, we defined the following four phases of contractions: 1) Po, a stea...

abstract since amphibians feeds on insects, they have crucial role in controlling the population of pests in various ecosystems. although their importance is clear, but systematics and biodiversity of them has been poorly studied. the aim of this research, conducted in 2014, is to identify amphibians of talesh township and their biological roles in pest control. sampling procedure has been done...

Experimental and clinical data have incriminated excess gastric acid secretion as an important factor in the development of duodenal ulcer. On the other hand, gastric ulcer is characteristically associated with normal to low levels of acid secretion, and mucosal resistance factors have been invoked to explain the pathogenesis. The purpose of this report is to summarize the evidence favouring th...
