Due to the ability of birds to travel long distances in the air, the potential feeding area of each individual is much larger than that of typical terrestrial animals. This makes birds a convenient indicator of environmental lead (Pb) pollution over large areas, in particular areas of inland and coastal ...
The incidence and spatial distribution of polycyclic aromatic hydrocarbons (PAHs) in the Buffalo River Estuary in the Eastern Cape Province of South Africa were assessed in this study. A total of 60 surface water and 19 sediment samples were collected from 5 sites of the estuary over a period of 6 months ...
A survey was conducted to determine the diversity of fish in Pergau Lake, Jeli, Kelantan, Malaysia from 2 September to 18 October of 2016. Fish samples were collected at seven random sampling stations around the lake by using setting trap method. The collected samples were preserved in 10% formalin ...
Neoliberal conservation has recently become a topic of academic research and a method of practice within the context of globalization. Less attention has been given to how neoliberal conservation has been practiced at the urban scale. This paper draws on the concept of ‘urban-growth-oriented green grabbing’ ...
The nostalgia that Victor Hugo expressed in Les Misérables for old-fashioned sailing ships was equaled only by his disdain for the newfangled steam-powered ones: “A thing which smoked and clacked on the Seine, making the noise of a swimming dog, came and went beneath the windows of the Tuileries. It ...
Whoever you are—a scientist or painter, a farmer or philosopher, a young mother or wrinkled grandparent—a radical shift in how you look at the world typically begins with a single moment of awakening. In one instant, something happens that crystallizes a whole set of thoughts and observations into a ...
Internet of things (IoT) is a promising technology which provides efficient and reliable solutions towards the modernization of several domains. IoT based solutions are being developed to automatically maintain and monitor agricultural farms with minimal human involvement. The article presents many ...
Cabled underwater information networks (CUINs) have evolved over the last decade to provide abundant power and broad bandwidth communication to enable marine science. To ensure reliable operation of CUINs, it is essential to have the technology for high-impedance fault diagnosis and isolation with high ...
Marine platforms require appropriate protections against corrosion attack for defining their useful life. In part I of this study, rule based analyses were carried out for designing cathodic protection system of a ship. Two reputable rules DNV-RP-B401 and Defstan (NES 704) standards were used for the ...
Due to the increase in automation during the transition to maintenance-free ship power plants and the reduction in the number of machine crews, the increase in the number of diagnostic tools during the transition from scheduled preventive maintenance of power plant components to repairs according to ...
In this paper, the design of sliding mode controller for a singular biological economic model with a stage structure and uncertain parameters is studied. First, a biological economic system with uncertain parameters for the invasion of alien species is modeled by a singular system. Then, according to ...
ABSTRACT One of the key strategic objectives of the World Health Organisation’s global antimicrobial resistance (AMR) action plan is to improve public awareness and understanding of this issue. Very few AMR awareness campaigns have targeted the animal production sector, particularly in low- and middle-income ...
Abstract Polar ecosystems are bellwether indicators of climate change and offer insights into ecological resilience. In this study, we describe contrasting responses to an apparent regime shift of two very different benthic communities in McMurdo Sound, Antarctica. We compared species‐specific patterns ...
A pesticide is a chemical substance used for the disposal of pests, such as insects, weeds, invertebrates, or rodents. Pesticides interfere with the normal metabolism of the target species; however, some of them may inadvertently affect organisms other than those targeted. Increased quantities of pesticides ...
Rocky benthic communities are common in Antarctic coastal habitats; yet little is known about their carbon turnover rates. Here, we performed a broad survey of shallow ( < 65 m depth) rocky ice-scoured habitats of South Bay (Doumer Island, Western Antarctic Peninsula), combining (i) biodiversity ...
Procaine penicillin (PP) is a β-lactam antibiotic widely used in human and veterinary medicine. Although PP is detected in surface water, little is known on its effects on aquatic invertebrates. Our aim was to determine the influence of PP on swimming behaviour (track density, swimming speed, turning ...
A diverse and abundant fouling community dominated by Lessepsian non-indigenous species was identified on a 13.5-m-long steel buoy stranded on the Israeli coast but originating from Port Said, at the Mediterranean entrance of the Suez Canal, Egypt. The molluscan community was sampled quantitatively ...
The scarcity of water can result in a direct conflict between the protection of aquatic resources and water use. For many agencies, environmental flow (EF) methods are essential in environmental impact assessments and in the protection of important fisheries resources. The objective of this paper is ...
Food is not only fundamental to our existence, its consumption, handling or even the mere sight of its also brings us immense joy. Over the years, technology has played a crucial part in supporting and enriching food-related practices, beginning from how we grow, to how we cook, eat and dispose of food. ...
In aquaculture, water quality is influenced by excessive feeding, a high breeding density, the species composition and the distribution of algae species. Traditional buoys can only collect water quality data at a fixed depth, and it is impossible to measure the water quality at different depths in the ...
