Ranaviruses are causing mass amphibian die-offs in North America, Europe and Asia, and have been implicated in the decline of common frog (Rana temporaria) populations in the UK. Despite this, we have very little understanding of the environmental drivers of disease occurrence and prevalence. Using ...
The Pacific oyster, Crassostrea gigas, is the most important commercial oyster species cultivated in the world. Meanwhile, the ostreid herpesvirus 1 (OsHV-1) is one of the major pathogens affecting the Pacific oyster, and numerous mortality outbreaks related to this pathogen are now reported worldwide. ...
A neural code based on sequences of spikes can consume a significant portion of the brain's energy budget. Thus, energy considerations would dictate that spiking activity be kept as low as possible. However, a high spike-rate improves the coding and representation of signals in spike trains, particularly ...
Background Dietary supplements are taken by about half of Americans. Knowledge of dietary supplement use is important because they may interact with prescription drugs or other supplements, cause adverse reactions including psychiatric symptoms, or contain inherently toxic ingredients or contaminants. ...
Marking organisms with fluorescent dyes and powders is a common technique used in ecological field studies that monitor movement of organisms to examine life history traits, behaviors, and population dynamics. External fluorescent marking is relatively inexpensive and can be readily employed to quickly ...
In the coastal countries of East Asia and Southeast Asia, ciguatera should be common because of the extensive tropical and subtropical coral reefs along the coasts and in the neighboring seas with ciguatoxic fishes. An extensive search of journal databases, the Internet and the government websites was ...
Statistical models often use observational data to predict phenomena; however, interpreting model terms to understand their influence can be problematic. This issue poses a challenge in species conservation where setting priorities requires estimating influences of potential stressors using observational ...
Global climate change is expected to have major effects on host-parasite dynamics, with potentially enormous consequences for entire ecosystems. To develop an accurate prognostic framework, theoretical models must be supported by empirical research. We investigated potential changes in host-parasite ...
This study investigated effects of microalgae (Rhodomonas baltica) and heterotrophic protists (Oxyrrhis marina) on the daily growth, activity, condition and feeding success of Atlantic herring (Clupea harengus) larvae from hatch, through the end of the endogenous (yolk sac) period. Yolk sac larvae were ...
Antifouling and drag reduction of ships are two critical issues in the shipping industry, which significantly affect the efficiency, safety, reliability of ships. Drag reduction by the bionic jet surface is an effective approach for reducing the energy consumption of ships. However, complicated by the ...
The subject of this article is analysis of the methods of Earth Observing in Intelligent Transport Systems (ITS) and Smart Cities and technical characteristics of satellite data. The first part of this article presents the analysis of satellite images of the Earth's surface illumination in villages, ...
The behavioral modeling reported in this work is computationally efficient for use in modeling distributed currents and potentials throughout the open-form conductor that is the ship's structure. Physics-based modeling is used to form a multiport S-parameter behavioral model of the ship's structure ...
The paper is devoted to approbation in laboratory and field conditions of a new method of bio — indication of aquatic ecosystem state on the basis of assessment of functional state of freshwater bivalve mollusks by monitoring of their cardiac activity.
Objective: Pregnancy is a special period of increased nutritional needs during which conscious nutritional support is required. Insufficient and imbalanced nutrition in this period of life causes serious conditions that affect both child and mother. This study aimed to evaluate the relationship between ...
Aim: The present study was undertaken with the prime objective of isolating and identifying Listeria spp. from various foods of animal origin sold at retail market outlets in the city of Navsari, Gujarat. Materials and Methods: Total 200 samples comprising of milk, milk products, meat, and fish (50 ...
The objective of this study was to evaluate the exopolysaccharide (EPS) production by Rhizobium leguminosarum cultivated in wastewater generated by oil companies (WWOC1 and WWOC2) and fish processing industry (WWFP). The results obtained in Erlenmeyer flasks indicated that the rhizobial strain grew ...
Salt evaporation ponds have played an important role as habitat for migratory waterbirds across the world, however, efforts to restore and manage these habitats to maximize their conservation value has proven to be challenging. For example, salinity reduction has been a goal for restoring and managing ...
Salinity is an important ecological factor affecting the survival of fish, and, to a certain extent, the increase of the salinity value will directly cause the death of a large number of freshwater fish. Therefore, it is very necessary to establish the freshwater fish salinity-mortality curve, and to ...
The Ocean is vast and of difficult access. Recent technological advances have brought us to a new era in ocean research (physical / biological / chemical / geological) one in which an Integrated network of Ocean Observing Systems (IOOS), involving strong developments in systems engineering and informatics, ...
