The desert zone also accounts for about a third of the state's surface area. The Chihuahuan Desert is an international biome that also extends into the neighboring Mexican state of Coahuila and into the U.S. states of Texas and New Mexico. The desert zone is mainly of flat topography with some small mountain ranges that run north to south. The desert in the state varies slightly with a small variant in climate. The lower elevations of the desert zone are found in the north along the Rio Grande which experience hotter temperatures in the summer and winter while the southern portion of the desert zone experiences cooler temperatures due to its higher elevation. The Samalayuca dunes cover an area of about 150 km2; it is an impressive site of the Chihuahuan Desert and is a protected area by the state due to unique species of plants and animals.

Norwegian researchers at the University of Troms have shown that some Arctic animals (ptarmigan, reindeer) show circadian rhythms only in the parts of the year that have daily sunrises and sunsets. In one study of reindeer, animals at 70 degrees North showed circadian rhythms in the autumn, winter and spring, but not in the summer. Reindeer on Svalbard at 78 degrees North showed such rhythms only in autumn and spring. The researchers suspect that other Arctic animals as well may not show circadian rhythms in the constant light of summer and the constant dark of winter.
What aninmals do researchers think might also show a variance in circadian rhythms in different seasons?
other Arctic animals

Problem: Please answer a question about the following article about Immaculate Conception:
Further claims were made that the Roman Catholic Church derives its doctrine from the Islamic teaching. In volume 5 of his Decline and Fall of the Roman Empire, published in 1788, Edward Gibbon wrote: "The Latin Church has not disdained to borrow from the Koran the immaculate conception of his virgin mother." That he was speaking of her immaculate conception by her mother, not of her own virginal conception of Jesus, is shown by his footnote: "In the xiith century the immaculate conception was condemned by St. Bernard as a presumptuous novelty." In the aftermath of the definition of the dogma in 1854, this charge was repeated: "Strange as it may appear, that the doctrine which the church of Rome has promulgated, with so much pomp and ceremony, 'for the destruction of all heresies, and the confirmation of the faith of her adherents', should have its origin in the Mohametan Bible; yet the testimony of such authorities as Gibbon, and Sale, and Forster, and Gagnier, and Maracci, leave no doubt as to the marvellous fact."
Who is the author of the texts entailed in the fifth part of the the collection about the Roman Catholic Church ?
A:
Edward Gibbon
