Ocean acidification (OA) is widely recognized as a significant oceanic threat in connection with other oceanic stressors, including warming and deoxygenation. Recent work shows that ocean acidification will negatively affect calcification processes for many species, including reef-building corals. It ...
Hydrodynamic response of a moored surface buoy has been experimentally evaluated in the present study. This buoy has been designed by National Institute of Ocean Technology (NIOT) to suit the functional requirements. A Froude scale model has been adopted and the floating body characteristics such as ...
Encounters between Scandinavian brown bears (Ursus arctos) and humans that result in human injuries and fatalities typically coincide with den entry in October and November, and commonly occur near a den. Our aim was to determine when bears arrive at their dens, identify potential predictors of this ...
Freshwater cetaceans are among the data deficient and now recognized as the most threatened group of marine mammals. Large scale studies are required to be done on an urgent basis to ensure reasonable chance of survival for these species. A detailed analysis of the freshwater habitats globally, indicate ...
The difference between maximum metabolic rate and standard metabolic rate is referred to as aerobic scope, and because it constrains performance it is suggested to constitute a key limiting process prescribing how fish may cope with or adapt to climate warming. We use an evolutionary bioenergetics model ...
The culture of fish in cages has become a practical and successful method in oceans to get good yield in fish production without going to deep sea. Our system contains a fish cage and an electronic system which makes the cage system submerge to a desired depth to protect fish during adverse weather ...
Aim: This study was designed to describe a series of in vitro tests that may aid the discovery of probiotic strains from actinomycetes. Materials and Methods: Actinomycetes were isolated from marine sediments using four different isolation media, followed by antimicrobial activity and toxicity assessment ...
This study investigated the perceptions on and adaptations to climate change impacts of 235 pangasius farmers in the Mekong Delta, Vietnam. Data were collected using semi-structured household surveys in six provinces, from three regions along the Mekong river branches. A Chi-Square test was used to ...
Different types of submersible dredgers are conceived, modeled and even some prototype and full-scale vehicles are built for prospective subsea excavation purposes by various researchers and commercial companies. Most common type of submersible dredgers is tracked vehicle. Walking submersible dredgers ...
The Mumbai Metropolitan Region (MMR), located to the east of the Arabian Sea, experiences tropical climate with annual rainfall of over 250 cms. Geographically, the Thane Creek separates the island city from the mainland comprising low-lying marshy lands, and is lined by north-south trending hills on ...
Mangrove forests provide important ecosystem goods and services for human society. Extensive coastal development in many developing countries has converted mangrove forests to other land uses without regard to their ecosystem service values; thus, the ecosystem state of mangrove forests is critical ...
The aim of this study was to evaluate the use of gonadal alterations in the thinlip grey mullet (Liza ramada) as a biological indicator in assessing aquatic ecosystems health, with particular emphasis to river ecosystems exposed to sewage discharges. For this purpose, the reproductive status and the ...
The aim of this study was to evaluate the diagnostic performance of in-house FISH (fluorescence in situ hybridisation) procedures for the direct identification of invasive fungal infections in blood cultures and cerebrospinal fluid (CSF) samples and to compare these FISH results with those obtained ...
Background Very limited nutritional epidemiological studies conducted to explore the unique dietary exposure in Newfoundland and Labrador (NL). This study aims to identify and characterize major dietary patterns in the target-population from general adult NL residents and assess the associations with ...
Background Salmonella species are widespread in the environment, and occur in cattle, pigs, and birds, including poultry and free-living birds. In this study, we determined the occurrence of Salmonella in different wild bird species in Poland, focusing on five Salmonella serovars monitored in poultry ...
Background Glyphosate, the active ingredient in Roundup formulations, is the most widely used herbicide worldwide, and as a result contaminates surface waters and has been detected in food residues, drinking water and human urine, raising concerns for potential environmental and human health impacts. ...
According to theory, adaptive radiation is triggered by ecological opportunity that can arise through the colonization of new habitats, the extinction of antagonists or the origin of key innovations. In the course of an adaptive radiation, diversification and morphological evolution are expected to ...
Microcystin-LR (MC-LR) has been detected extensively in the aquatic environment and has the potential to disturb the thyroid endocrine system. However, limited information is available on the effects of subacute MC-LR exposure on fish thyroid hormone (TH) metabolism. In the present study, juvenile zebrafish ...
