Ianiropsis (G.O. Sars, 1897-99) is a complex and poorly understood genus composed of species similar to one another (BRUSCA & IVERSON, 1985), as well as similar to Janira (Leach, 1814). Species within this genus are mainly indigenous in the Pacific Ocean, apart from Ianiropsis breviremis (G.O. Sars, 1883), which occurs in the North-East Atlantic, and Ianiropsis palpalis (Barnard, 1914) on the S...
total of 35 species of leucosiid crabs have been recorded by several authors and the current survey from the persian gulf. here, zoogeography of these species and their zoogeographical affinities within indo-west pacific region are discussed. in addition, present taxonomic survey off the iranian coasts of the persian gulf resulted in finding 14 leucosiid crabs, of which arcania erinacea and par...
Land cover mapping in mountainous areas is a notoriously challenging task due to the rugged terrain and high spatial heterogeneity of land surfaces as well as the frequent cloud contamination of satellite imagery. Taking Southwestern China (a typical mountainous region) as an example, this paper established a new HC-MMK approach (Hierarchical Classification based on Multi-source and Multi-tempo...
The integration between vegetation data, human disturbance factors, and geo-spatial data (Digital Elevation Model (DEM) and image data) is a particular challenge for vegetation mapping in mountainous areas. The present study aimed to incorporate the relationships between species distribution (or vegetation spatial distribution pattern) and topography and human disturbance factors with remote se...
The aim of our study was to describe and compare nutritional status and food related behaviours in rural pregnant women of Li ethnicity as they had been divided into mountainous and costal groups by residential area. One hundred and ninety-six randomly selected healthy rural pregnant women of Li ethnicity for the mountainous group (MG), and eighty-two for the coastal group (CG) were recruited. ...
the aim of this study was to investigate on obtained caviar quantity status of sturgeon at fishing grounds of the southwestern caspian sea. data of catches by means of fixed gill nets in sturgeon fish fishing grounds and beach seine were used during 5 years survey (2005-2009). a total of 1361 female sturgeon was caught including: 788 acipenser persicus, 410 a. stellatus, 60 a. guldenstaedti, 70...
This paper shows that the location of the shoreface bank reefs along the northeastern and eastern coasts of Brazil, in a first order approximation, seem to be controlled by the deficit of sediment in the coastal system. The sediment transport pattern defined by a numerical modeling of wave refraction diagrams, representing circa 2000 km of the northeastern and eastern coasts of Brazil, permitte...
