Fierce predatory freshwater fishes, the species of Percocypris (Cyprinidae, Teleostei) inhabit large rivers or lakes, and have a specific distribution pattern. Only a single species or subspecies occurs in each large-scale drainage basin of the Southeastern Tibetan Plateau. In this study, the molecular ...
Background Gonad differentiation is one of the most important developmental events in vertebrates. Some heat shock proteins are associated with gonad development. Heat shock protein 70 (Hsp70) in the teleost fish and its roles in sex differentiation are poorly understood. Methods and Findings We ...
Near-shore coral reef systems are experiencing increased sediment supply due to conversion of forests to other land uses. Counteracting increased sediment loads requires an understanding of the relationship between forest cover and sediment supply, and how this relationship might change in the future. ...
Moreton Bay, Queensland, Australia is an area of high biodiversity and conservation value and home to two sympatric sub-populations of Indo-Pacific bottlenose dolphins (Tursiops aduncus). These dolphins live in close proximity to major urban developments. Successful management requires information regarding ...
Numerous studies have applied genetic tools to the identification of source populations and transport pathways for invasive species. However, there are many gaps in the knowledge obtained from such studies because comprehensive and meaningful spatial sampling to meet these goals is difficult to achieve. ...
Bacteriocins are attracting increased attention as an alternative to classic antibiotics in the fight against infectious disease and multidrug resistant pathogens. Bacillus subtilis strain MMA7 isolated from the marine sponge Haliclona simulans displays a broad spectrum antimicrobial activity, which ...
Marine Protected Areas (MPAs) have been widely proposed as a fisheries management tool in addition to their conservation purposes. Despite this, few studies have satisfactorily assessed the dynamics of fishers’ adaptations to the loss of fishing grounds. Here we used data from before, during and after ...
If the primary goal of artificial reef construction is the creation of additional reef habitat that is comparable to adjacent natural rocky-reef, then performance should be evaluated using simultaneous comparisons with adjacent natural habitats. Using baited remote underwater video (BRUV) fish assemblages ...
Using 3 cyprinid fish species zebra fish, rare minnow, and juvenile grass carp, we conducted assays of lethal reaction and ventilatory response to analyze sensitivity of the fish to 4 heavy metals. Our results showed that the 96 h LC50 of Hg2+ to zebra fish, juvenile grass carp, and rare minnow were ...
Background Cold-water diving requires good thermal insulation because hypothermia is a serious risk. Water conducts heat more efficiently compared to air. To stay warm during a dive, the choice of thermal protection should be based on physical activity, the temperature of the water, and the duration ...
The impact on coastal ecosystems of suspended solids, organic matter, and bacteria in shrimp farm effluents is presented. Sites around Bahía de Kino were selected for comparative evaluation. Effluent entering Bahia Kino (1) enters Laguna La Cruz (2). A control site (3) was outside the influence of effluents. ...
Antimicrobial peptides (AMPs) are humoral innate immune components of fishes that provide protection against pathogenic infections. Histone derived antimicrobial peptides are reported to actively participate in the immune defenses of fishes. Present study deals with identification of putative antimicrobial ...
The MORPH project (FP 7, 2012-2016) aims at the development of efficient methods and tools to map the underwater environment in situations that defy existing technology. Namely, missions that involve underwater surveying and marine habitat mapping of rugged terrain and structures with full 3D complexity, ...
Autonomous Underwater Vehicles (AUVs) have found their application in exploration and surveillance. This paper proposes a cooperative distributed search algorithm based on a minimum entropy approach for AUVs with capabilities like multi agent exploration. The work is motivated by the project “Thesaurus”, ...
Indentifying potential pollution sources from the monitoring water quality data is desirable for water quality management. A simple expert system module was developed in this paper to infer the latent pollution sources and explain variation in water quality parameters. It contains three parts. The first ...
An adaptive self-aligning underwater navigation system based on data fusion from a set of multiple sensors including a MEMS-based inertial measurement unit (IMU), a Doppler Velocity Log (DVL), a 3-axis magnetic compass, and a pressure sensor for depth measurement is proposed. These sensors are typically ...
From observations and numerical model results we have detected spatial and temporal variability of the environmental conditions in fjords on the order of hours and hundreds of meters. This leads to patches of infectious agents or bulks of warmer or colder water being advected around in regions with ...
Very small scale reciprocal sound propagation experiment has carried out since 2006 in Hashirimizu Port, Tokyo Bay. The distance between the transducers is 110 m and the average depth of the area is about 6 m. M- sequence phase modulated signal was sent each other with the duration of 30 s in reciprocally. ...
This paper describes our progress towards the development of field deployable pCO2 and NH3 in water measurement technologies. The fluorescence lifetime based pCO2 technology described here has a wide dynamic range of 102-5 × 104 microatmospheres and has undergone numerous field trials that indicate ...
The FP7 funded TROPOS project approach is to develop a modular multi-use platform for use in deep waters, with a focus on the Mediterranean, tropical and sub-tropical regions. In this paper, three different platforms configurations, - which have been designed to show the synergies and compatibilities ...
