Butterflies of the high-altitude Atacama Desert: habitat use and conservation
The butterfly fauna of the high-altitude desert of Northern Chile, though depauperate, shows high endemism, is poorly known and is of considerable conservation concern. This study surveys butterflies along the Andean slope between 2400 and 5000 m asl (prepuna, puna and Andean steppe habitats) as well as in high and low-altitude wetlands and in the neoriparian vegetation of agricultural sites. W...
متن کاملUltraviolet and yellow reflectance but not fluorescence is important for visual discrimination of conspecifics by Heliconius erato.
Toxic Heliconius butterflies have yellow hindwing bars that - unlike those of their closest relatives - reflect ultraviolet (UV) and long wavelength light, and also fluoresce. The pigment in the yellow scales is 3-hydroxy-dl-kynurenine (3-OHK), which is found in the hair and scales of a variety of animals. In other butterflies like pierids with color schemes characterized by independent sources...
متن کاملCerebral Venous Sinus Thrombosis Masquerading as High Altitude Cerebral Edema at Extreme Altitude
Introduction: Extreme altitude travel has gained popularity globally for adventurous, scientific, and military endeavors. Cerebral venous sinus thrombosis (CVST) at extreme altitude is a rare, covert, and emergent condition requiring immediate intervention. Case Presentation: A case of CVST masqueraded as high altitude cerebral edema (HACE) at 6700 m/22000 ft i...
متن کاملPhylogenetic and structural analysis of the HbA (a/b) and HbD (a/b) hemoglobin genes in two high-altitude waterfowl from the Himalayas and the Andes: Bar-headed goose (Anser indicus) and Andean goose (Chloephaga melanoptera)
Two species of waterfowl living at high altitude provide a prominent example of parallel adaptation at the molecular level. The bar-headed goose (Anser indicus) breeds at high elevations in central Asia and migrates across the Himalayas, where the partial pressure of oxygen (O2) is one-third of sea level. In South America, the distantly related Andean goose (Chloephaga melanoptera) is endemic t...
متن کاملPterin pigment granules are responsible for both broadband light scattering and wavelength selective absorption in the wing scales of pierid butterflies.
A small but growing literature indicates that many animal colours are produced by combinations of structural and pigmentary mechanisms. We investigated one such complex colour phenotype: the highly chromatic wing colours of pierid butterflies including oranges, yellows and patterns which appear white to the human eye, but strongly absorb the ultraviolet (UV) wavelengths visible to butterflies. ...
