The symposium ‘‘Genomics and Vertebrate Adaptive Radiation: A Celebration of the First Cichlid Genome’’ was held at the annual meeting for the Society of Integrative and Comparative Biology in Boston in January, 2009. While the central topic was the genomics of adaptive radiation in cichlid fishes, the symposium integrated speakers studying genotype-to-phenotype maps in other model organisms. G...

In our study we taught a female African Grey 11 Italian words: vowel-like sounds were extracted from comprehensible words after critical listening, and pitch frequency (Pkf) was measured for the first three formants of each vowel. Similarly, formants from human vowels were isolated and measured. The analysis run on formant frequencies mean values of both samples revealed that human vowels could...

Abstract Random lasers had been made by some biomaterials as light scattering materials, but natural photonic crystals have rarely reported materials. Here we demonstrate the ability of to drive laser actions sandwiched feathers Turquoise-Fronted Amazon parrot and dye between two plastic films. Parrot comprise abundant crystals, different color compose ratios crystal, which directly affect feat...

A usability study to explore the naturalness of piloting the Parrot AR.Drone, using input devices designed to manipulate 3D graphics.

A 35-year-old Indian parrot (Psittacula krameri manillensis) was presented to the Department of Veterinary Surgery & Radiology, West Bengal University of Animal and Fishery Sciences with a history of blepharospasm and corneal lesion OS. Test with fluorescein dye was negative. The dense corneal opacity (macula) was identified as involving the posterior corneal layer. The further ophthalmic exami...

A unique community-funded project in Puerto Rico has launched whole-genome sequencing of the critically endangered Puerto Rican Parrot (Amazona vittata), with interpretation by genome bioinformaticians and students, and deposition into public online databases. This is the first article that focuses on the whole genome of a parrot species, one endemic to the USA and recently threatened with exti...

Parrot is a virtual machine designed to be a target for languages that have traditionally been run using an interpreter. The virtual machine and its assembly language include many high-level features such as objects, thread synchronization support, and garbage collection. It is set apart from other virtual machines by its register-machine structure, while many other contemporary VMs use a stack...

Aggressive mimicry is an adaptive tactic of parasitic or predatory species that closely resemble inoffensive models in order to increase fitness via predatory gains. Although similarity of distantly related species is often intuitively implicated with mimicry, the exact mechanisms and evolutionary causes remain elusive in many cases. Here, we report a complex aggressive mimicry strategy in Plec...

Owing to its high degree of complexity and plasticity, the cichlid pharyngeal jaw apparatus has often been described as a key evolutionary innovation. The majority of studies investigating pharyngeal muscle behavior and function have done so in the context of feeding. Analysis of enzyme activities (citrate synthase, 3-hydroxyacyl-CoA dehydrogenase and L-lactate dehydrogenase) of pharyngeal musc...

An agent-based simulation has been built to model speciation in cichlid fishes in the Great Lakes of Africa. A real natural system has been chosen as the target of simulation, rather than a generalised system. This focusses research towards open problems in cichlid biology, and provides a library of field research to drive the design and parametrisation of the simulation. Visualisations of the ...
