Mammalia, Didelphimorphia and Rodentia, central Santa Fe Province, Argentina

Three owl pellets samples collected in the localities of Pedro Gómez Cello (= Estación Km. 197; 30°02’14” S, 60°18’56” W), Colonia Silva (= Estación Abipones; 30°26’59” S, 60°25’58” W) and Jacinto L. Arauz (30°44’01” S, 60°58’31” W), Province of Santa Fe, Argentina, were studied. We registered 11 genera of small mammals, including Didelphidae marsupials (1 species), and Caviidae (1), Cricetidae (10), and Muridae (1) rodents. We documented the southernmost record for Pseudoryzomys simplex and the first and second recording localities for Santa Fe of Oligoryzomys nigripes and Graomys chacoensis, respectively

Range extension of Tympanoctomys barrerae (Lawrence, 1941) (Rodentia: Octodontidae) in Patagonia and southernmost record

We report the southernmost record for the octodontid rodent T. barrerae, which is also the second recording locality for this species in Patagonia. The new locality is placed in S Neuquén province, extending the known range of the species about 150 km SW from the nearest previous record. Although T. barrerae is considered a highly specialized rodent of salar flats in Monte desert, the record reported here came from an arbustive rocky environment belonging to the Monte- Patagonia ecotone

Of the silmarils and the ring: J. R. R. Tolkien\u27s fiction and the importance of creation and art

J. R. R. Tolkien embodies the opposing ideals of Enchantment and the Machine in the Silmarils and the One Ring respectively. These created objects oppose each other just as Tolkien’s ideals of art do. Enchantment is art’s ideal, it\u27s purpose is to glorify and enrich the beauty of reality through subcreation. The Silmarils exhibit the delight of making and perceiving beauty. Whereas the Machine is art’s shadowy reflection that utilizes apparatuses or devices rather than personal talent in order to coerce others and reality itself. Overall Tolkien\u27s aesthetic theories reflect many fears surrounding modern attitudes toward weaponizing art. Tolkien supplies Enchantment as the solution to these problems surrounding art and creativity in an oppressively technological world

The genus <i>Akodon</i> (Muroidea: Sigmodontinae) in Misiones, Argentina

Our understanding of the rodent diversity from the Argentinean Atlantic rainforest and its surrounding environments (Misiones Province) is still relatively poor. Here we present an update on the species inhabiting Misiones of the genus Akodon. Integrated analyses of morphology, chromosomal and molecular data allow us to document the existence of four species of Akodon in the province. One of these is apparently undescribed, and is known only from one locality in the ‘campos’ phytogeographic unit of southern Misiones. A second species, A. montensis, has a large distribution and is one of the dominant sigmodontine species in primary and secondary forest. Akodon sp. 2, previously reported as either A. serrensis and A. paranaensis, is known from only one locality at the northeast of the province, where it is sympatric with A. montensis. Also in sympatry with A. montensis at one locality in central Misiones there is a similar species with a gall bladder referred here to A. cursor. Finally, the previous reference of one specimen to A. serrensis must be discarded due to the referred specimen is lost, and the data at hand are insufficient to corroborate the identity of the specimen under question. As Misiones has the largest continuous patches of southern interior Atlantic rainforest remaining in Argentina we pose comments on the conservation significance of our study.Facultad de Ciencias Naturales y Muse
