Comparative rates of natural osteological disorders in a collection of Paraguayan birds

Osteological development of the vertebral column, paired, dorsal and anal fins in Rutilus caspicus, Pravdin (1927) (Teleostei: Cyprinidae)

Study of the osteological development in fishes is important from fisheries, biology and aquaculture points of views. It can be used as an early bio-indicator of non-optimal rearing conditions. The Caspian roach, Rutilus caspicus is a native cyprinid fish of the Caspian Sea that its artificial propagation has fulfilled in hatcheries to recruit its natural stocks. Hence, this study was conducted...

Experimental and Numerical Studies of Paraguayan Chaco Natural Gas in a Counterflow Diffusion Flame

Combustion is a chemical phenomenon in which a multitude of elementary chemical reactions take place, resulting in the overall process of fuel oxidation. Natural gas fuel has been explored for a few decades and extracted for a few years in the region of Paraguayan Chaco, near Bolivia border. Currently, natural gas is not very important in Paraguay’s energy matrix, however it could be in the nea...

Using ecological niche modeling to determine avian richness hotspots

Understanding distributions of wildlife species is a key step towards identifying biodiversity hotspots and designing effective conservation strategies. In this paper, the spatial pattern of diversity of birds in Golestan Province, Iran was estimated. Ecological niche modeling was used to determine distributions of 144 bird species across the province using a maximum entropy algorithm. Richness...
