Jumping from the surface of water by the long-legged fly Hydrophorus (Diptera, Dolichopodidae).
The fly Hydrophorus alboflorens (4 mm long, 4.7 mg mass) moves around upon and jumps from water without its tarsi penetrating the surface. All six tarsi have a surface area of 1.3 mm(-2) in contact with the water, but they did not dimple its surface when standing. Jumping was propelled by depression of the trochantera of both hind and middle legs, which are 40% longer than the front legs and 17...
متن کاملSpectral tuning in halorhodopsin: the chloride pump photoreceptor.
The spectral tuning of halorhodopsin from Halobacterium salinarum (shR) during anion transport was analyzed at the molecular level using DFT-QM/MM [SORCI+Q//B3LYP/6-31G(d):Amber96] hybrid methods. Insights into the influence of Cl(-) depletion, Cl(-) substitution by N3(-) or NO3(-), and mutation of key amino acid residues along the ion translocation pathway (H95A, H95R, Q105E, R108H, R108I, R10...
متن کاملHaromyia, a new genus of long-legged flies from Dominica (Diptera: Dolichopodidae).
The new micro-dolichopodid genus Haromyia gen. nov. and the type species H. iviei sp. nov. are described from the island of Dominica in the Lesser Antilles. Males and females of Haromyia are distinguished by the large setae on a bulging clypeus, minute size, and wing veins that are nearly straight and evenly diverging from wing base. Haromyia does not fit readily into any contemporary dolichopo...
متن کاملSpectral Tuning of Phototaxis by a Go-Opsin in the Rhabdomeric Eyes of Platynereis
Phototaxis is characteristic of the pelagic larval stage of most bottom-dwelling marine invertebrates. Larval phototaxis is mediated by simple eyes that can express various types of light-sensitive G-protein-coupled receptors known as opsins. Since opsins diversified early during metazoan evolution in the marine environment, understanding underwater light detection could elucidate this diversif...
متن کاملPhotoreceptor spectral sensitivities: Common shape in the long-wavelength region
Previous measurements of mammalian photoreceptor spectral sensitivity have been analysed, with particular attention to the long-wavelength region. The measurements selected for study come from rod and cone systems, and from human, monkey, bovine and squirrel sources. For the spectra from photoreceptor electrophysiology and from psychophysical sensitivity, the frequency scaling applied by Mansfi...
