The identification of species constitutes the first basic step in phylogenetic studies, biodiversity monitoring and conservation. DNA barcoding, i.e. the sequencing of a short standardized region of DNA, has been proposed as a new tool for animal species identification. The present study provides an ...
Increasing anthropogenic pressures urge enhanced knowledge and understanding of the current state of marine biodiversity. This baseline information is pivotal to explore present trends, detect future modifications and propose adequate management actions for marine ecosystems. Coralligenous outcrops ...
Background Marine sponges can associate with abundant and diverse consortia of microbial symbionts. However, associated bacteria remain unexamined for the majority of host sponges and few studies use phylogenetic metrics to quantify symbiont community diversity. DNA fingerprinting techniques, such ...
Background Schistosomiasis japonica, caused by contact with Schistosoma japonicum cercaria-infested water when washing, bathing or production, remains a major public-health concern in China. The purpose of the present study was to investigate the effect of a suspension concentrate of niclosamide (SCN) ...
There has been substantial recent change in coral reef communities. To date, most analyses have focussed on static patterns or changes in single variables such as coral cover. However, little is known about how community-level changes occur at large spatial scales. Here, we develop Markov models of ...
Addressing concerns about security of energy supply, sustainability and climate change drives the shift towards greener economies based on a combination of energy efficiency and renewable energy systems. Although this transition is accelerating, many economic and technical challenges remain. The development ...
This study explores the use of multi-stage machine learning based classifiers and feature selection techniques in the classification and identification of fish parasites. Accurate identification of pathogens is a key to their control and as a proof of concept, the monogenean worm genus Gyrodactylus, ...
The rural venture farm needs to develop improved methods for evaluating the performance of its projects. We are interested in the problems of the implementation of a rabbit-breeding farm. One of the first decisions to be taken refers to the type of the structure for housing the animals. In general, ...
The rational use of water resources in agriculture is a key factor to achieve true sustainable development. The propagation speed of the wetting front is of great importance for water usage optimization in irritation scheduling. This paper presents the design and construction of an automated wetting ...
In this paper an optical carbon dioxide (CO2) lifetime-based sensor designed for the continuous monitoring of low CO2 levels in aqueous solution in fields of fish farming and in oceanography is described. The presented optical measurement unit consists of a CO2 sensitive layer mounted onto the end of ...
Food safety has become one of the world's most concerns. Foodborne diseases have become an important factor affecting public health. Biological and chemical substances pollution impact food safety more severely. The doubt of genetically modified (GM) foods safety did not eliminate. The China's food ...
Catastrophe refers to natural disasters that caused huge damages to people's lives and property. Catastrophe insurance is a form of insurance through which the risks caused by natural disasters like earthquakes, hurricanes, tsunamis, floods can be dispersed. In recent years, the importance of catastrophe ...
White Spot Syndrome Virus (WSSV) is an infectious pathogen of shrimp and other crustaceans, and neither effective vaccines nor adequate treatments are currently available. WSSV is an enveloped dsDNA virus, and one of its major envelope proteins, VP28, plays a pivotal role in WSSV infection. In an attempt ...
Polymerase chain reaction (PCR)-clamping using blocking primer and DNA-analogs, such as peptide nucleotide acid (PNA), may be used to selectively amplify target DNA for molecular diet analysis. We investigated PCR-clamping efficiency by studying PNA position and mismatch with complementary DNA by designing ...
A large number of viruses have been described in many different reptiles. These viruses include arboviruses that primarily infect mammals or birds as well as viruses that are specific for reptiles. Interest in arboviruses infecting reptiles has mainly focused on the role reptiles may play in the epidemiology ...
We evaluate hypotheses for meso-scale spatial structure in an orange roughy (Hoplostethus atlanticus) stock using samples collected during research trawl surveys off the east coast of New Zealand. Distance-based linear models and generalised additive models were used to identify the most significant ...
Water is a valued natural resource for the existence of all living organisms. Management of the quality of this precious resource is, therefore, of special importance. In this study river water samples were collected and analysed for physicochemical and bacteriological evaluation of pollution in the ...
Little is known about the microevolutionary processes shaping within river population genetic structure of aquatic organisms characterized by high levels of homing and spawning site fidelity. Using a microsatellite panel, we observed complex and highly significant levels of intrariver population genetic ...
This paper reviews the animal foraging literature for insights into the directed, persistent search problem in rescue robotics, where a robot may have to move away from a target or out of sensing range in order to find a path to it. The conclusions from 32 papers on empirical studies of insects, fish ...
