Benthic ecosystem cascade effects in Antarctica using Bayesian network inference

Antarctic sea-floor communities are unique, and more closely resemble those of the Palaeozoic than equivalent contemporary habitats. However, comparatively little is known about the processes that structure these communities or how they might respond to anthropogenic change. In order to investigate ...

Substrate-dependent fish have shifted less in distribution under climate change

Analyses of the impacts of climate change on fish species have primarily considered dynamic oceanographic variables that are the output of predictive models, yet fish species distributions are determined by much more than just variables such as ocean temperature. Functionally diverse species are differentially ...

Fisheries management tools to support coastal and marine spatial planning: A case study from the Northern Gulf of California, Mexico

A management approach was developed that combined spatial and non-spatial tools to inform a Coastal and Marine Spatial Planning Process (CMSP) in the Puerto Peñasco-Puerto Lobos Coastal Corridor, Northern Gulf of California, Sonora, Mexico. Four fisheries management tools were applied with an emphasis ...

Belly flap from Norwegian spring-spawning herring (Clupea harengus L.): A potentially new product with high content of vitamin D, EPA and DHA

Processing Norwegian spring-spawning herring (NSSH) yields large amounts of rest raw material which currently is used mainly for production of fish oil and fish meal for feed in aquaculture. However, belly flaps from NSSH might be a profitable resource as a food product. This study investigates the ...

Applied Research of BeiDou Communication Module in Aquaculture

The positioning function and short message communication function of Beidou satellite navigation system are applied to aquaculture monitoring and play a role in related systems by combining Beidou communication positioning technology with aquaculture monitoring. This paper studies a monitoring terminal ...

Offshore LoRaWAN Networking: Transmission Performances Analysis Under Different Environmental Conditions

This article presents the architecture and the performances of a long-range wide-area network (LoRaWAN) infrastructure used for data transmission from a floating sensor node placed in the middle of the sea to a multigateway structure positioned on the coast, whose purpose is the monitoring of offshore ...

Elements of fish metacommunity structure in Neotropical freshwater streams

Abstract The identification of the mechanisms underlying patterns of species co‐occurrence is a way to identify which process(es) (niche, neutral, or both) structure metacommunities. The current paper had the goal of identifying patterns of co‐occurrence in Neotropical stream fish and determining which ...

Food Sustainability Knowledge and Attitudes in the Spanish Adult Population: A Cross-Sectional Study

Moving towards sustainable food systems and food consumption are proposed as strategies to reduce environmental impact. However, these strategies require joint action between different stakeholders, including the general population’s knowledge and perception, as final consumers. To assess the knowledge ...

Framework for a Community Health Observing System for the Gulf of Mexico Region: Preparing for Future Disasters

The Gulf of Mexico (GoM) region is prone to disasters, including recurrent oil spills, hurricanes, floods, industrial accidents, harmful algal blooms, and the current COVID-19 pandemic. The GoM and other regions of the U.S. lack sufficient baseline health information to identify, attribute, mitigate, ...

Coexisting with sharks: a novel, socially acceptable and non-lethal shark mitigation approach

Conflict between humans and large predators is a longstanding challenge that can present negative consequences for humans and wildlife. Sharks have a global distribution and are considered to pose a potential threat to humans; concurrently many shark species are themselves threatened. Developing strategies ...

The constraint of ignoring the subtidal water climatology in evaluating the changes of coralligenous reefs due to heating events

Predicting community-level responses to seawater warming is a pressing goal of global change ecologists. How far such predictions can be derived from a fine gradient of thermal environments needs to be explored, even if ignoring water climatology does not allow estimating subtidal marine heat waves. ...

Coastal pollution from the industrial park Quintero bay of central Chile: Effects on abundance, morphology, and development of the kelp Lessonia spicata (Phaeophyceae)

The industrial park of Quintero Bay (QB) in the central coast of Chile was established in the 1960s, presents high levels of pollution due to the industrial activity, and it is known as one of the five Chilean “sacrifice zones”. Lessonia spicata is the most important habitat-forming kelp species in ...

Renibacterium salmoninarum—The Causative Agent of Bacterial Kidney Disease in Salmonid Fish

Renibacterium salmoninarum is one of the oldest known bacterial pathogens of fish. This Gram-positive bacterium is the causative agent of bacterial kidney disease, a chronic infection that is mostly known to infect salmonid fish at low temperatures. Externally, infected fish can display exophthalmia ...

Comparing Genomic Signatures of Selection Between the Abbassa Strain and Eight Wild Populations of Nile Tilapia (Oreochromis niloticus) in Egypt

Domestication to captive rearing conditions, along with targeted selective breeding have genetic consequences that vary from those in wild environments. Nile tilapia (Oreochromis niloticus) is one of the most translocated and farmed aquaculture species globally, farmed throughout Asia, North and South ...

A low-cost smart system for electrophoresis-based nucleic acids detection at the visible spectrum

Nucleic acid detection by electrophoresis is still a quick and accessible technique for many diagnosis methods, primarily at research laboratories or at the point of care units. Standard protocols detect DNA/RNA molecules through specific bound chemical dyes using a UV-transilluminator or UV-photo documentation ...

System and method for providing information on fuel savings, safe operation, and maintenance by real-time predictive monitoring and predictive controlling of aerodynamic ...

Disclosed is a system and method for monitoring a physical change of a marine structure which includes a complex optical measuring instrument for detecting a behavior and structural change of the marine structure by using at least one optical sensor by means of optical fiber Bragg grating. A physical ...

Method for assisting a person in acting in a dynamic environment and corresponding system

A method for assisting a person in assessing a dynamic environment comprises steps of obtaining information on states of at least two entities in a common environment, predicting a future behavior of each of the entities on the basis of the obtained information, estimating a time to event for at least ...

Method, communication system, transmitting and receiving device for radio-based communication data transmission

- Transmission of the communication data by means of the first radio communication system from at least one first transmission unit to at least one first reception unit, one or more first transmission frequencies being assigned to the first radio communication system, and transmission of at least one ...

Energy-saving heating wearable combination

An energy-saving heating wearable apparatus (100) mainly includes a control unit (10), a heating unit (30), a temperature sensing unit (60), and a humidity sensing unit (70). The control unit (10) controls the heating unit (30) to continuously heat when an ambient temperature or a biological body temperature ...

Device for measuring blood flow

The invention relates to a measurement device for the blood flow of an individual, for example for the detection of bubbles. The device comprises an acoustic emitter and a case with an emission surface capping the acoustic emitter. The emission surface is terminated at one end by a clavicular contact ...
