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 ...

Archaeological finds of personal ornaments reveal not only behavioural patterns of the society they belong to, but also their forms of manifestations indicate connections, contacts and communication paths, exchange networks and movements of prehistoric populations. This paper advances the current knowledge regarding ornamental traditions in Eastern Adriatic area during Late Upper Palaeolithic a...

Asplenium nidus L. commonly called as Bird’s Nest Fern, is a threatened, ornamental fern, which is widely used as novel foliage ornamental plant and local people use it in worship. The taxon is threatened due to over exploitation, habitat destruction and genetic barriers. To understand the constraints in the regeneration, reproductive biology studies are made. It is observed that more sporophyt...

The evergreen shrub, Gardenia jasminoides Ellis var. grandiflora Nakai is one of the most popular garden-plants, with significant ornamental importance. Here, we have cloned improved random amplified polymorphic DNA (RAPD) derived fragments into T-vector, and developed sequence-characterized amplified region (SCAR) markers. These markers have been deposited in GenBank database with the accession...

Betalains are tyrosine-derived red-violet and yellow plant pigments known for their antioxidant activity, health-promoting properties, and wide use as food colorants and dietary supplements. By coexpressing three genes of the recently elucidated betalain biosynthetic pathway, we demonstrate the heterologous production of these pigments in a variety of plants, including three major food crops: t...

Quantitative genetic studies frequently utilize inbred strains of animals as tools for partitioning the direct and indirect effects of genes from environmental effects in generating an observed phenotype, however, this approach is rarely applied to behavioral studies. Guppies, Poecilia reticulata, perform a set of anti-predator behaviors that may provide an ideal system to study how complex beh...

A total of 281 specimens of freshwater armored ornamental fish species (Leporacanthicus galaxias,Lasiancistrus saetiger, Cochliodon sp., Hypostomus sp., Pseudacanthicus spinosus, Ancistrus sp. and Rineloricaria cf. lanceolata) were captured at the hydrological basin of Guamá River, Pará, Brazil. The infection by Trypanosoma spp. was inspected. The morphological and morphometric characterization...
