Background. The primary environmental risk associated with artisanal small-scale gold mining (ASGM) activities in Sekotong and Taliwang is waste discharged directly into the environment. This waste contains variable concentrations of heavy metals and a high level of mercury. When these elements are ...
Background. Harmful wastes and other dangerous industrial by-products constitute major sources of environmental pollutants in Nigeria. Industrial pollutants discharged into the environment contain organic and inorganic pollutants in dissolved, suspended and insoluble forms. Fishes are known for their ...
Background Eurycea sosorum (Barton Springs salamander) and Eurycea nana (San Macros salamander) are listed as endangered and threatened species, respectively, by the U.S. Fish and Wildlife Service (USFWS) with habitats restricted to small regions near Austin, Texas, USA. The conservation efforts with ...
Milk fat depression (MFD) is characterized by a reduction in the content of milk fat, presumably caused by the anti-lipogenic effects of rumen biohydrogenation intermediates, such as trans-10 cis-12 conjugated linoleic acid (CLA). In this study, RNA-Seq technology was used to help elucidate the mammary ...
Chondrichthyes - sharks, rays, skates, and chimeras, are among the most threatened and data deficient vertebrate species. Global demand for shark and ray derived products, drives unregulated and exploitative fishing practices, which are in turn facilitated by the lack of ecological data required for ...
Habitat shifts that occur during the life cycles of marine fishes influence population connectivity and structure. A generalized additive modeling approach was used to characterize relationships between environmental variables and the relative abundance of red snapper Lutjanus campechanus over unconsolidated ...
A selectively inflatable watersports inflation device is disclosed. The device is a vest or another wearable device having an inner layer, an outer layer, and a bladder between the inner and outer layers. The device also includes one or more canisters coupled to the bladder and configured to selectively ...
Method for determining the time of receipt by a radio receiver (320,330,340) of a binary coded radio message emitted by a sender (310), whereby the radio signal is received by the receiver so that an analogue electrical signal is achieved, which analogue signal is sampled and optionally demodulated, ...
A survival craft comprises a hull (10) formed from inflatable members (12, 13) and mounting a powered propulsion system (18, 19) for the survival craft. A superstructure (11) is mounted on the hull and formed from inflatable members (25, 26, 29a-29i) and a flexible roof (28) supported by the inflatable ...
Large-scale harmful algal blooms (HABs) occur in the coastal waters of the northern Beibu Gulf, China, and have deleterious effects on the marine ecosystem. The frequency, duration, and extent of HAB events in this region have increased over the last 30 years. However, the underlying causes of HABs ...
Records of δ18O in stream flow are critical for understanding and modeling hydrological, ecological, biogeochemical and atmospheric processes. However, the number of such records are extremely limited globally and the length of such time series are usually less than a decade. This situation severely ...
Lo scopo dell'invenzione è fornire una soluzione che superi alcuni degli inconvenienti noti fino ad ora nel settore. L'invenzione sfrutta una nuova caratteristica aerodinamica, un amplificatore di flusso, che aumenta la velocità del lato di aspirazione della porta della rete a strascico, generando così ...
An apparatus for harvesting aquatic animals has a cod end portion and an elongate lengthener portion. The cod end portion has an open leading end and a closed trailing end and side wall(s), the side wall(s) and the trailing end being substantially impervious to water. The elongate lengthener portion ...
Disclosed is a method for guiding aquatic organisms. The method includes disposing a plurality of electrode units at a distance from one another in water; and applying an electrical pulse to at least one electrode unit of the plurality of electrode units to generate an electric field and/or a magnetic ...
Abstract In order to investigate the effects of fat level and protein and other components on lipid bioaccessibility, the bioaccessibility of total lipids and particular fatty acids ( FAs) of fish samples with different fat levels (5.4% w/w, 10.2% w/w, and 16.6% w/w) and cod liver oil supplement in ...
This review highlights recent studies of the functional implications of corticosteroids in some important behaviors of model fish, which are also relevant to human nutrition homeostasis. The primary actions of corticosteroids are mediated by glucocorticoid receptor (GR) and mineralocorticoid receptor ...
Hepatitis (HEV) is widely distributed in pigs and is transmitted with increasing numbers to humans by contact with pigs, contaminated food and blood transfusion. The virus is mostly apathogenic in pigs but may enhance the pathogenicity of other pig viruses. In humans, infection can lead to acute and ...
Collapses and regime changes are pervasive in complex systems (such as marine ecosystems) governed by multiple stressors. The demise of Atlantic cod (Gadus morhua) stocks constitutes a text book example of the consequences of overexploiting marine living resources, yet the drivers of these nearly synchronous ...
The recent ubiquitous detection of PRV among salmonids has sparked international concern about the cardiorespiratory performance of infected wild and farmed salmon. Piscine orthoreovirus (PRV) has been shown to create substantial viremia in salmon by targeting erythrocytes for principle replication. ...
Background Older adults often suffer from age- and behavior-related brain changes affecting neuronal functioning and, therefore, cognitive and motor functions. The improvement of these functions might decrease falls and improve mobility. Previous studies indicate that video game-based physical exercise, ...
