During the course of a telemetry study on three species of Australian frogs (Litoria caerulea, Litoria dahlii and Cyclorana australis), we found that many of the surgically implanted transmitters had migrated into the bladder. We subsequently implanted small beads into L. caerulea and they were expelled from the body in 10-23 days. Beads implanted into cane toads (Rhinella marina) to document t...

Samples of liver and kidney of Little Blue Heron (Egretta caerulea) collected on Sepetiba Bay, Rio de Janeiro, Brazil, were analysed for their copper, zinc, cadmium, lead, chromium and nickel content. Mean concentration levels in liver and kidney (μg.g dry weight) were 6.32955 and 6.57136 (Cd); 78.17409 and 96.89409 (Zn); 44.01727 and 65.20864 (Cu); 41.15091 and 39.62318 (Pb); 2.80091 and 4.164...

In a study conducted in the gallery forest of the Vale doVeu de Noiva in the Parque Nacional da Chapada dos Guimarães, Mato Grosso state, chemical baits were used to attract and sample male orchid bees. From September 2003 to July 2005, male euglossine bees were captured monthly, from 8:00 a.m. to 4:00 p.m. as they arrived at the baits. Of the 264 males captured, eight males belonged to Aglae c...

Song complexity is thought to be a sexually selected trait in passerine birds; however, quantifying relevant parameters of song complexity is the first step in testing the theory that song complexity is a sexually selected trait. We show here that blue grosbeak (Guiraca caerulea) males sing a single song type but the properties of that song type vary between renditions. This pattern of song del...

This study was undertaken to examine the antioxidant activity of methanolic extract of seeds of Trigonella foenum-graecum seeds using DPPH free radical scavenging assay. The IC50 (The concentration of sample required to scavenge 50% of DPPH free radical) was calculated by plotting graph between % inhibition vs concentration. The Ascorbic acid was used as standard antioxidant in comparison to me...

To investigate the absorption and the inhibition of glucose by the aqueous seed extracts of Trigonella foenum gracum. The small intestine of all animals were removed, washed with 0.9% (w/v) normal saline and intestinal segments were everted the empty sac was filled with 0.5 ml of the KHB buffer and placed in a stoppered conical flask with 5 ml of the buffer with varying concentration of glucose...

This study reveals the peculiar in vivo cell kinetics and cell turnover of the marine sponge Halisarca caerulea under steady-state conditions. The tropical coral reef sponge shows an extremely high proliferation activity, a short cell cycle duration and massive cell shedding. Cell turnover is predominantly confined to a single cell population, i.e. the choanocytes, and in this process apoptosis...

Trichodischia Bigot, 1885 is a Neotropical genus with confusing taxonomic history. This was initially composed of two species: T. caerulea and soror 1885. Later, the Trichoraea Cortés, 1974 erected for caerulea. When reviewing history both species, we discovered that genera have been considered synonymous based on erroneous information without formal synonymy being proposed. Herein, redescribed...

Microfungi were recovered from all parts of a municipal water distribution system in sub-tropical Australia even though virtually no colony-forming units were recovered from the treated water as it left the treatment plant. A study was then undertaken to determine the potential sources of the microfungal population in the distribution system. Observation of frogs (Litoria caerulea) using the in...

Objective: Scutellaria luteo-caerulea Bornm. & Snit. is one of the species of genus Scutellaria, within the family of the Lamiaceae, that is used for immune system stimulation and antibacterial effects in traditional medicine in Iran. The aims of this study were to analyze essential oils and mineral element contents of leaves of  S. luteo-caerulea in flowering stage of development. Materials an...
