Total dissolved gas (TDG) supersaturation has been identified as one of the possible negative environmental effects of the construction of dams in the upper Yangtze River. Juvenile Chinese sucker and Prenant’s schizothoracin fish were selected to evaluate the impact of TDG supersaturation on the swimming ...
Several reproductive strategies have been identified as key factors that contribute to the establishment and dispersal of invasive species in new environments. These strategies include early maturity, high reproductive capacity and flexibility in timing of reproduction. It is therefore critical to investigate ...
This study proposes and discusses a multi-scale spatial planning method implemented simultaneously at local and national level to prioritize ecosystem management actions across landscapes and seascapes. Mismatches in scale between the occurrence of biodiversity patterns and ecological processes, and ...
Anaerobic granulation at elevated salinities has been discussed in several analytical and engineering based studies. They report either enhanced or decreased efficiencies in relation to different Na+ levels. To evaluate this discrepancy, we focused on the microbial and structural dynamics of granules ...
Abstract Marine microbes encounter a myriad of biotic and abiotic factors that can impact fitness by limiting their range and capacity to move between habitats. This is especially true for environmentally transmitted bacteria that cycle between their hosts and the surrounding habitat. As geologic history, ...
Abstract. Case–control studies are conducted to identify cholera transmission routes. Water, sanitation, and hygiene (WASH) exposures can facilitate cholera transmission (risk factors) or interrupt transmission (protective factors). To our knowledge, the association between WASH exposures and cholera ...
Background The environmental pathogen, Mycobacterium ulcerans (MU) can infect both humans and animals and cause Buruli ulcer (BU) disease. However, its mode(s) of transmission from the colonized environment to human/animal hosts remain unclear. In Australia, MU can infect both wildlife and domestic ...
Background Changes in climate are predicted to influence parasite and pathogen infection patterns in terrestrial and marine environments. Increases in temperature in particular may greatly alter biological processes, such as host-parasite interactions. For example, parasites could differentially benefit ...
Prophages are known to encode important virulence factors in the human pathogen Vibrio cholerae. However, little is known about the occurrence and composition of prophage-encoded traits in environmental vibrios. A database of 5,674 prophage-like elements constructed from 1,874 Vibrio genome sequences, ...
As a global problem in coastal environments, harmful algal blooms (HABs) have seriously affected the health of coastal ecosystems and regional economies. Here we report an aerosol-trigger mechanism for the occurrence of HABs based on long-term field data and laboratory experiments. The occurrence times ...
A natural pH gradient caused by marine CO2 seeps off the Methana peninsula (Saronikos Gulf, eastern Peloponnese peninsula) was used as a natural laboratory to assess potential effects of ocean acidification on coccolithophores. Coccolithophore communities were therefore investigated in plankton samples ...
The aim of the present study was to evaluate the marketing policies of lobsters as influenced by different practices related to product quality in seven supermarkets located in Italy. Retailers were divided in two categories: large scale and medium scale. The two groups were compared to screen for differences ...
Classification of Maritime Vessels is a recurrent task in maritime surveillance systems. Classification can be conducted by different methods, e.g., Naïve Bayes, $pmb{k}$ Nearest Neighbor, Decision Tree, Fuzzy Rule, or Neural Networks. The Automatic Identification System (AIS) is cooperative system ...
Drowning has become the highest cause of unintentional death across the world accounting for 7% of all injury-related deaths. According to WHO nearly 3, 60,000 people die from drowning every year. Even people who are well versed with swimming are not spared from this threat. This includes fishermen, ...
Conference review The offshore oil and gas sector is beginning to recover 2 years after oil prices bottomed out, which has led to cautious optimism in the sector. At this year’s Offshore Technology Conference, held 30 April–3 May in Houston, that feeling was evident, although there is still a strong ...
Vessel detection and type recognition is crucial in any maritime surveillance application. This component aims at preventing or investigating unlawful actions present at sea. Modern very high resolution (VHR) optical satellite sensors are able to capture images with spatial resolution up to 0.3m per ...
Massive communication constellations in development such as OneWeb are redefining the concept of constellations, offering serial production of hundreds of satellites with a low recurrent cost. In this SAR constellation concept Airbus has taken such a low cost platform with the benefits it offers and ...
This study aimed to quantitatively analyze the trends of environmental research that utilizes environmental spatial information using a text mining technique. The analysis was conducted on a total of 869 papers published in Korea based on 20 environmental spatial information areas, and the results showed ...
In this paper we demonstrate how deep learning can be applied to the field of sea surveillance by classifying ship types from their trajectories. Commercial ships using AIS continually report information such as their ship type, e.g. fishing or cargo ship. A problem with AIS information however is that ...
The usual elliptical validation regions may not give a good representation of the possible vehicle positions if the time period of the prediction is long compared to the time scales of vehicle maneuvers. This paper proposes a fast, non-elliptical validation region giving a better coverage of the possible ...
