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...

Many people who suffer from seasonal inhal ant allergy in other sections of the United States, come to Florida to escape from offensive pollens at home, inasmuch as airborne pollen grains are commonly declared to be the princi pal exciting cause of such respiratory afflictions, and change of regional residence has in many cases brought relief (7). However, some vic tims who migrate to South Flo...

Despite considerable research effort, it remains unclear whether extra-pair fertilizations (EPF) drive the evolution of male secondary ornamentation in socially monogamous systems. In this study, we test the hypothesis that EPF contribute to the evolution or maintenance of male feather ornamentation in a sexually dichromatic passerine, the Scarlet Rosefinch, Carpodacus erythrinus. We show that ...

DNA barcoding is a tool for species identification. For plant species identification, two of plastid genes (rbcL and matK) were used as standard barcodes. There are limitations of each gene marker but matK is considered to be the closest plant analogue to the CO1 animal barcode. As a mega-biodiversity country, Indonesia has many plant species used for ornamental and/or medical purposes. This st...

The objective of the present study was to evaluate the parasite fauna of four species of ornamental fish collected in the Chumucuí River, municipality of Bragança, Pará, Brazil. From June 2006 to December 2007. Fishes (n=307) belonging to four species were collected, including 23 specimens of Moenkhausia sanctaefilomenae (redeye tetra), 37 Carnegiella strigata (marbled hatchetfish), 7 Chilodus ...
