Saltwater tolerance is a trait that carries both ecological and epidemiological significance for Anopheles mosquitoes that transmit human malaria, as it plays a key role in determining their habitat use and ecological distribution, and thus their local contribution to malaria transmission. Here, we lay the groundwork for genetic dissection of this trait by quantifying saltwater tolerance in thr...

A multidisciplinary study involving hydrogeochemical sampling and borehole geophysics was undertaken to study the nature and occurrence of saline groundwater on two islands in British Columbia, Canada. Saturna and Hornby Islands are located at the south and north ends, respectively, of the Canadian Gulf Islands situated off the lower mainland of British Columbia. Two large-scale geochemical sam...

This study quantified the electrosensitivity of a euryhaline elasmobranch, the Atlantic stingray (Dasyatis sabina) across a range of salinities. Specimens from a permanent freshwater (FW) population in the St Johns River system, FL, USA, were compared with stingrays from the tidally dynamic Indian River Lagoon in east Florida, USA. Behavioral responses of stingrays to prey-simulating electric s...

Abstract:   A two-dimensional fully implicit finite difference model, which can be easily extended to three dimensions, is developed to study the effect of cut-off walls on saltwater intrusion into the aquifers. This model consists of a coupled system of two nonlinear partial differential equations which describe unsteady density-driven groundwater flow and solute transport. The numerica...

In the culture of freshwater and saltwater aquatic species, feeding is one of the most challenging stages. During this period of life, larvae are very sensitive and many of them need special food to meet their needs, if the food does not meet the needs of larvae in terms of nutrient composition and physical characteristics such as size and shape, the survival and growth of the larvae will be se...

Honey bees (Apis mellifera anatolica) were subjected to sequential trials where they were given the choice between a feature-positive and a feature-negative feeding plate. The 'feature' being manipulated is the presence of a single blue circle among three circles marking the location of a small sucrose reward. That is, a 'feature-negative' target had three white circles, while a 'feature-positi...

Growth of American eels, Anguilla rostrata (Lesueur), sampled in saltwater bays and adjacent freshwater ponds in the southern Gulf of St. Lawrence, Canada, was estimated by otolith annulus back-calculation, and related to salinity of growth habitat as determined using otolith strontium:calcium ratios. Eels resident in salt water grew on average in length 2.2 times faster than freshwater residen...
