Species with dispersal mediated by planktonic larvae are expected to be more likely to show temporal genetic variation, due to differences in larval mortality and dispersal ability. The shanny Lipophrys pholis is a typical benthic rocky intertidal fish and its dispersion is limited to its long larval stage. In contrast, the sand-smelt Atherina presbyter has a very short planktonic life, small size and weak swimming capabilities, which translates into reduced dispersion potential. A total of 226 ...

Indonesia as an archipelagic nation highly requires a model of sea transportation as interconnection mainframe between islands. An effective and efficient use of sea transportation is the main factor to improve Indonesian economy. Therefore, it is necessary to optimize the sea transportation model that services throughout Indonesian sea. It has been known that an alternative solution to this specific need is the use of Semi Trimaran Flat Hull Ship. The main supporting reason is the good stabilit...

As the accident of a vessel impacting a bridge pier will cause serious disaster, such as destroyed bridge, sinking ship and polluting environment, the technology and method to protect bridge pier from ship collision have been widely investigated recently. Due to the huge kinetic energy of large-tonnage ship and the short time duration in the collision, the studies involve impact mechanics. A developed flexible crashworthy device has been developed to protect bridges, which consists of an outer s...

The paper treats a number of unique relics of the literature of the Urums - Turkish speaking Greeks settled in the Ukrainian part of the Azov sea region since 1780. Detailed archeographic descriptions of two codices, used in liturgical service in the Greek churches of Crimea and Azov sea region during the 18th-19th centuries, are presented. The structure of both manuscripts is typical for the Greek Church Evagelistarions with Saturday-Sunday Gospel lessons, in this case in Urum dialect, written ...

About one third of the anthropogenic carbon dioxide (CO<sub>2</sub>) released into the atmosphere in the past two centuries has been taken up by the ocean. As CO<sub>2</sub> invades the surface ocean, carbonate ion concentrations and pH are lowered. Laboratory studies indicate that this reduces the calcification rates of marine calcifying organisms, including planktic foraminifera. Such a reduction in calcification resulting from anthropogenic CO<sub>2</sub> emissions has not been observed, or q...

Reciprocal transplantation of Stylophora pistillata coral fragments between deep (30m) and shallow sites (3m) was conducted gradually and resulted with 100% survival. Photoacclimation of transplants at both depths showed two distinct phases: at the first phase, within two weeks, zooxanthellae density decreased below (at 3m) and increased beyond (at 30m) these of the control values at the new depth, while chlorophyll a per zooxanthellae cell remained as in the original depths, thereby fully adjus...

This paper asserts that three principal frameworks for climate change adaptation can be recognised in the literature: scenario-led (SL), vulnerability-led (VL) and decision-centric (DC) frameworks. A criterion is developed to differentiate these frameworks in recent adaptation projects. The criterion features six key hallmarks as follows: (1) use of climate model information; (2) analysis of metrics/units; (3) socio-economic knowledge; (4) stakeholder engagement; (5) adaptation of implementation...

Cold-water corals provide an important habitat for a rich fauna along the continental margins and slopes. Although these azooxanthellate corals are considered particularly sensitive to ocean acidification, their responses to natural variations in pH and aragonite saturation are largely unknown due to the difficulty of studying their ecology in deep waters. Previous SCUBA investigations have shown an exceptionally shallow population of the cold-water coral Desmophyllum dianthus in near-surface wa...

In tanks, fish behaviour and adaptations to these two types of substrate were observed. The fish were active for less than 2% of the time an average, but individual variability was high. A circadian rhythm of motility was observed. They swam with rowing movements of th...

Evidence suggests that marine management and conservation strategies, whether direc...

In June 2006 a new coordinated waterbird monitoring programme was developed within the framework of an Interreg project. Census data, gathered on the basis of a kilometric grid, were stored in a database and processed by a GIS, created for integration with all environmental databases. Preliminary maps, describing spatial variation of bird richness and abundance, are presented.

Radiography plays an important role in detection of interproximal caries. The aim of study is to compare diagnostic ability of photo stimulable phosphor (PSP) with direct measurement using stereomicroscope in detecting proximal caries. Hundred proximal surfaces of 50 extracted human posterior teeth were radiographed with dental X-ray unit. The image receptors used was storage phosphor plate Vista scan (size 2), (time of exposure 0.4 s). Radiographs were interpreted and caries lesions were classi...

Les contradictions dans les politiques publiques de conservation de la biodiversité sont inhérentes à la complexité des problématiques en jeu et des logiques d'acteurs. Comment désamorcer les conflits d'intérêts ? Comment améliorer l'appropriation collective des objectifs de conservation ? Des éléments de réflexion sont proposés à partir de l'exemple des politiques « poissons migrateurs ».<br>Contradictions in biodiversity conservation public policies are inherent in the complexity of the issues...

Incrementally grown, metabolically inert tissues such as fish otoliths provide biochemical records that can used to infer behavior and physiology throughout the lifetime of the individual. Organic tissues are particularly useful as the stable isotope composition of the organic component can provide information about diet, trophic level and location. Unfortunately, inert, incrementally grown organic tissues are relatively uncommon. The vertebrate eye lens, however, is formed via sequential deposi...

Introduction: Early identification of sepsis is critical as early treatment improves outcomes. We sought to identify threshold values of secretory phospholipase A2 (sPLA2)-IIA that predict sepsis and bacterial infection compared to nonseptic controls in an emergency department (ED) population. Materials and Methods: This is a prospective cohort of consenting adult patients who met two or more systemic inflammatory response syndrome (SIRS) criteria with clinical diagnosis of infectious source lik...

Objective: To explore the effect of fish oil at different concentrations on post-thawed semen of Kalang swamp buffalo. Methods: A total of 4 Kalang swamp buffalo bulls with 3-5 years of age and weighed about 340-360 kg were slected. Semen was regularly collected from these buffalo bulls once a week by an artificial vagina. Fish oil was supplementary at the dosages of 0 mg (control), 50 mg, 100 mg, 150 mg, and 200 mg to the extender (skim milk-egg yolk). Fresh, pre-freezing and frozen semen were ...

Exotic freshwater fish can have deleterious effects on local biodiversity, although these impacts often only become apparent many years after the introduction. Local Ecological Knowledge (LEK) may be a useful source of information in situations where formal technical studies are insufficient, but few works have examined the reliability of information generated through this approach. We examined the reliability of LEK by investigating the impacts of Nile tilapia on fishery stocks in an artificial...
