The present study was conducted on the gills structure and the gill surface area of 40 individuals of the Blue swimming crabs, Portunus pelagicus, and 40 Chinese mitten crabs, Eriocheir sinensis, specimens of the species were collected from the different regions of Shatt Al- Arab and North-west Arabian gulf. Both species were having eight phyllobranchiatesas of the same structure but different in length and surface area.

The uptake of amino acids by the non-gill epithelia of the mantle cavity of Mytilus edulis L. was studied and compared with uptake by the gills. Amino acid entry rates and the subsequent distribution of amino acids to the other tissues of the animals were studied using high-performance liquid chromatography and radiochemical techniques. Uptake via the non-gill epithelia lining the mantle cavity was separated from uptake via the gill by employing a preparation in which the gills were surgically removed. Amino acid uptake by such animals was compared with that of suitably sham-operated controls.

Common carp and African catfish belong to the Cyprinidae (Cypriniformes) and Catfish (Siluriformes) orders, respectively. They are characterized by a different habitat, as a result of which the structure of the gill apparatus has a number of features [3]. The article describes the macroscopic and microscopic morphology of the gills of the represented fish species. Each of them had four complete pairs of gills, and the fifth was rudimentary without gill filaments. The gill rakers of carp tended to be short and widely spaced compared to the long and thin rakers of catfish. The gill filaments of

Due to the chemico-physical differences between air and water, the transition from aquatic life to the land poses several challenges for animal evolution, necessitating morphological, physiological and behavioural adaptations.

Cutaneous surfaces initially accounted for the vast majority (approx. 96%) of the total area available for respiratory gas exchange. As fish grew, total branchial surface area expanded at a more rapid rate than cutaneous surface area and, thus, came to represent a progressively larger fraction of total surface area.

Oxygen intake for respiration, also carbon dioxide and, generally, ammonia elimination takes place across gas-exchange surfaces, usually the gills in fish. Water flows across gills, separated by the pharyngeal gill clefts, and supported by gill arches, and which possess highly folded surfaces covered by a very thin epithelium. Blood flow and water flow are separated only by the epithelium with a ‘countercurrent’ gas exchange between the two.

Abstract Morphometric relationships between selected body tissues and body mass are analysed for small gobies (Teleostei: Gobiodei). These species show large body surface areas relative to mass, which might be advantageous for facultative cutaneous respiration but potentially disadvantageous for osmoregulation and locomotion. Large body surface areas per unit mass and correlated drag forces could account for ‘transient’ modes of swimming in small fish. Some species show large mass-specific development of gill area and, in this respect, are thought to be paedomorphic. Gill development in miniat

While some populations are native, many fisheries are the result of introductions through stocking programs. These stockings can result in established fisheries while others fail to produce established populations. It is possible that a combination of physical, chemical, and biological variables produce an ideal environment for the successful establishment and survival of this species.

This paper is concerned with the optimal layout of gill cells for minimizing the differential deflection of a very large floating structure under a non-uniform load distribution over the surface of the structure. Gill cells are compartments in the floating structure where the bottom surface is perforated to allow water to flow freely in and out. At the locations of these gill cells, the buoyancy forces are eliminated. When placed appropriately, these gill cells are very cost effective in minimizing the differential deflection of the loaded structure. So the optimal layout of the gill cells is

Streszczenie:

Heat transfer and film cooling distributions have been acquired downstream from the exit of a nozzle guide vane gill slot (or cutback). Additionally, heat transfer and pressure drop data have been experimentally determined for a pin fin array within the gill slot geometry. Generally, average row pin fin heat transfer levels for the converging channel correlate quite well with archival literature. However, no generalized flow friction factor correlation was found to predict the pressure drop within the array. Experimental data for the region downstream from the gill slot have been acquired over

Streszczenie:

Climate warming is expected to degrade permafrost in many regions of the world. Degradation of permafrost has the potential to affect soil thermal, hydrological, and vegetation regimes. Projections of long-term effects of climate warming on high-latitude ecosystems require a coupled representation of soil thermal state and hydrological dynamics. Such a coupled framework was developed to explicitly simulate the soil moisture effects of soil thermal conductivity and heat capacity and its effects on hydrological response. In the coupled framework, the Geophysical Institute Permafrost Laboratory (
