...Radek Netušil; Kateřina Tomanová; Lenka Chodáková; Daniela Chvalová; David Doležel; Thorsten Ritz; Martin Vácha ABSTRACT Sensitivity to magnetic fields is dependent on the intensity and color of light in several animal species. The light-dependent magnetoreception working model points...

... ontogeny, only data collected from adults were included. For each recorded cone λ max value, we also recorded cone morphological type, which in part, is defined by the cell's number of light-sensitive outer segments (i.e. specialized stacks of membrane containing opsin). As such, λ max values were...

... and biogenic light. Although the recent availability of portable spectrometers has made it simpler to measure color, guidance on how to make these measurements has not kept pace. Because most biologists receive little training in optics, many measure the wrong thing, or measure the right thing in the wrong way...

...John Jellies Medicinal leeches are aquatic predators that inhabit surface waters during daylight and also leave the water where they might be exposed to less screened light. Whereas the leech visual system has been shown to respond to visible light, leeches in the genus Hirudo do not appear...

...Maoz Fine; Shai Sabbah; Nadav Shashar; Ove Hoegh-Guldberg SUMMARY Coral–algae symbiosis is a key feature of tropical corals and is highly dependent on the efficiency with which solar energy is attenuated by the coral. Scleractinian corals are among the most efficient light collectors in nature...

... of milliseconds. Shallow coral reefs can be exposed to wave lensing during light-wind, clear-sky conditions, which have been implicated as a secondary cause of mass coral bleaching through light stress. Management strategies to protect small areas of high-value reef from wave-lensed light stress were tested using...

...Melissa S. Roth; Michael I. Latz; Ralf Goericke; Dimitri D. Deheyn SUMMARY Reef-building corals inhabit high light environments and are dependent on photosynthetic endosymbiotic dinoflagellates for nutrition. While photoacclimation responses of the dinoflagellates to changes in illumination...

...Riccardo Rodolfo-Metalpa; Yannick Huot; Christine Ferrier-Pagès SUMMARY We investigated photoacclimation in the symbiotic Mediterranean coral Cladocora caespitosa by exposing it to three light levels (30, 80 and 250 μmol m –2 s –1 ), which are in the range of those recorded for this species...

...J. N. Lythgoe; Julia Shand ABSTRACT The reflectance from the iridophores in the skin of the neon tetra Paracheirodon innesi (Myers) and the iridophores in the cornea of the sand goby Pomatoschistus minutus (Pallas) changes in response to light. In both cases the reflectance comes from...

In a comparison of photomechanical responses of albino and normally pigmented axolotls, similar time courses and maxima of force development were...
