تعارفات کنش های گفتاری هستند که افراد در زندگی روزمر? خود به منظور برقراری دوستی یا تداوم روابط مسالمت آمیز به کار می برند. ساز و کار تعارف مختص زبان انگلیسی یا هر زبان دیگری نیست و پدیده ای است جهانی و در همه زبانها حضور دارد. تفاوتی که از این نظر در زبانها و فرهنگ ها وجود دارد مربوط به پاسخ به این کنش گفتاری در گفتمان است. این مطالعه به بررسی تنوع پاسخ های انگلیسی و عربی به کنش گفتاری تعارف د...

Zooplankton sample variability in a tidal estuary :

A series of 347 vertical zooplankton hauls was made at a 175-h anchor station in the upper St. Lawrence estuary, Quebec, and current meter profiles were recorded. The 95% confidence interval of a single observation in most of the copepod time series was about 25400% of the mean. Temporal variability consisted for the most part of semidiurnal fluctuations superimposed on a long term trend. Other...

Predation Risk Influences the Diving Behavior of a Marine Mesopredator

Exploring factors that influence diving behavior is critical to understanding energy budgets, habitat use, and exploitation rates of prey. Optimal diving behavior studies have focused primarily on trade-offs between oxygen recovery at the surface and energy intake at depth. General predictions from these models are often supported by empirical data, but a mismatch exists between theory and data...

Modeling the tidal and sub-tidal hydrodynamics in a shallow, micro-tidal estuary

Tidal forcing of enterococci at marine recreational beaches at fortnightly and semidiurnal frequencies.

Marine beach water quality is typically monitored in early morning once a week without respect to tidal condition. To assess the effect of tide on this public health warning system, we analyzed enterococci (ENT) data from 60 southern California marine beaches with differing geomorphology, orientation, and proximity to runoff sources. ENT concentrations during spring tides were significantly hig...
