The physiological mechanisms underlying local adaptation in natural populations of animals, and whether the same mechanisms contribute to adaptation and acclimation, are largely unknown. Therefore, we tested for evolutionary divergence in aerobic exercise physiology in laboratory bred, size-matched crosses of ancestral, benthic, normal Lake Whitefish (Coregonus clupeaformis) and derived, limnet...

The sensitivity of an enrichment culture procedure for detecting Clostridium botulinum type E in whitefish chubs (Leucichthys sp.) was assayed. Data demonstrated that fish inoculated with 10 or more viable C. botulinum spores regularly develop specifically neutralizable enrichment cultures. Mild heat treatment (60 C, 15 min) substantially reduced the sensitivity of enrichment culturing. This ef...

The stocking of hatchery-produced whitefish is a common practice in most countries of the species' natural range. Rigorous monitoring of the effects of stocking is less common , however, and possible negative impacts of stocking ontlle target population are rarely considered, even though supportive stocking might exelt a series of negative effects. The present study discusses Ulese potentiiLl i...

Sympatric fish populations observed in many north temperate lakes are among the best models to study the processes of population divergence and adaptive radiation. Despite considerable research on such systems, little is known about the associations between ecological conditions and the extent of ecotypic divergence. In this study, we examined the biotic and abiotic properties of postglacial la...

In the coming decades, global warming and increase in temperature, in different regions of the world, may change indoor and outdoor thermal comfort conditions and human health. The aim of this research was to study the effects of global warming on thermal comfort conditions in indoor ambiences in Iran. To study the increase in temperature, model for assessment of greenhouse-gas induced climate ...

Many small-scale fisheries are remote in nature, making data collection logistically difficult. Thus, there is a need for accessible solutions that address the gaps present these fisheries. One possible solution to incorporate photography into community- or harvest-based monitoring frameworks and employ images estimate biological data. Here, we test this approach using łuk dagaii, broad whitefi...

Microcystin-LR (MC-LR) is a potent hepatotoxin for which substantial gap in knowledge persists regarding the underlying molecular mechanisms of liver toxicity and injury. Although long non-coding RNAs (lncRNAs) have been extensively studied model organisms, our concerning role lncRNAs injury limited. Given that show low levels sequence conservation, their becomes even more unclear non-model org...

Persistent organic pollutants are a concern for species occupying high trophic levels since they can cause immunosuppression and impair reproduction. Mass mortalities due to canine distemper virus (CDV) occurred in Caspian seals (Pusa caspica), in spring of 1997, 2000 and 2001, but the potential role of organochlorine exposure in these epizootics remains undetermined. Here we integrate Caspian ...
