The adult female and first-instar nymph of a new species of armoured scale insect, Poliaspoides bambusae sp.n. (Diaspididae), is described and illustrated. The new species was collected in Turkey on imported ornamental Bambusa siamensis (Poaceae) from an unknown source.

introduction: fish mycobacteriosis is caused by the non-tuberculous mycobacteria. infected fish are normally the primary source of infection, although non-tuberculous mycobacteria can be found in the environment. the present study was designed to  investigate the few recently found suspected cases of mycobacteriosis in iranian ornamental fish tanks.   materials and methods: pathological specime...

Phytoremediation offers a cost-effective, non-intrusive, and safe alternative to conventional cleanup techniques. In this study, we used ornamental hydrophytes plants as constructed wetlands to treat urban or rural domestic wastewater. Most ornamental hydrophytes adapted to the wastewater well, and were fairly efficient in scavenging BOD5 (biological oxygen demand 5 d), COD (chemical oxygen dem...

Current knowledge on the prevalence and genotypes of Cryptosporidium in fishes is still limited. This study investigated the prevalence of Cryptosporidium species in 171 ornamental fishes, belonging to 33 species, collected from 8 commercial aquariums around Perth, Western Australia. All samples were screened by nested PCR targeting the 18S rRNA locus. A total of 6 positives were identified by ...

Nephrocalcinosis is a chronic disorder which may be resulted in decrease in growth rate and finally mortality in severe condition. Nephrocalcinosis is defined as the presence of calcification in the kidney. A total number of 80 ornamental fishes of different species included of discus fish (Symphysodon discus), angelfish (Pterohyllum sp.), goldfish (Carassius auratus) and oscar fish (Astronotus...

Nature of Work: The development of new and superior plants helps to stimulate excitement and demand, improve competitiveness and profitability, and ultimately deliver superior and more diverse products to consumers. Numerous sources of novel traits have provided the current diversity in ornamental plants including wild collections of whole plants and seeds, open-pollinated seedling selection, r...

We present a technique for drawing ornamental designs consisting of placed instances of simple shapes. These shapes, which we call elements, are selected from a small library of templates. The elements are deformed to flow along a direction field interpolated from user-supplied strokes, giving a sense of visual flow to the final composition, and constrained to lie within a container region. Our...
