Respiratory Turbinates of Canids and Felids: a Quantitative Comparison

(Accepted 31 March 2004) Abstract The respiratory turbinates of mammals are complex bony plates within the nasal chamber that are covered with moist epithelium and provide an extensive surface area for the exchange of heat and water. Given their functional importance, maxilloturbinate size and structure are expected to vary predictably among species adapted to different environments. Here the ﬁrst quantitative analysis is provided of maxilloturbinate structure based on high-resolution computed tomography (CT) scans of the skulls of eight canid and seven felid species. The key parameters examined were the density of the maxilloturbinate bones within the nasal chamber and how that density varied along the air pathway. In both canids and felids, total maxilloturbinate chamber volume and bone volume increased with body size, with canids having c. 1.5–2.0 times the volume of maxilloturbinate than felids of similar size. In all species, the volume of the maxilloturbinates varies from rostral to caudal, with the peak volume occurring approximately midway, close to where airway cross-sectional area is greatest.

Today, people can purchase these garments in many stores all over the world. 20 5 Changing Colors with the Seasons The fur of some Arctic animals changes from the woodland colors of the fall to pure white like winter snow. If they kept their woodland colors, these Arctic animals would stand out in the white snow and they would be unprotected. So, their fur must change to white. As a result, the animals can hide in the snow from their enemies and search safely for food.

Snowy Owl Bubo Scandiacus ILLINOIS RANGE Adult
snowy owl Bubo scandiacus Kingdom: Animalia FEATURES Phylum: Chordata The snowy owl averages 20 to 27 inches in length Class: Aves (tail tip to bill tip in preserved specimen). This bird Order: Strigiformes has white feathers with dark ﬂecks. The snowy owl has a large, round head with a circlelike appearance Family: Strigidae on its ﬂattened face. Its huge, yellow eyes face ILLINOIS STATUS forward. This bird of prey (meat eater) has a hooked bill and claws to help in capturing and eating its common, native food. © Chris Young, State Journal-Register BEHAVIORS The snowy owl is an Arctic owl that occasionally winters in Illinois, mainly in the northern one-half of the state. When present, it may be seen in prairies, fields, marshes, lake edges, airports, golf courses and cities where it is active during the day. It may perch on the ground or on more elevated objects. Spring migrants leave Illinois in March. In summer, the snowy owl lives in the tundra. Fall migration into Illinois seems to be somewhat dependent on prey population sizes in more northern areas. When the prey population levels are low, there is a better chance for the birds to winter in Illinois. Fall adult migrants usually appear in November. The snowy owl feeds on small mammals and birds. It usually does not make sounds but may give a “krow-ow” call in the breeding season. ILLINOIS RANGE © Rick Remington © Illinois Department of Natural Resources. 2020. Biodiversity of Illinois.

Appendix Lagomorph Species: Geographical Distribution and Conservation Status
Appendix Lagomorph Species: Geographical Distribution and Conservation Status PAULO C. ALVES1* AND KLAUS HACKLÄNDER2 Lagomorph taxonomy is traditionally controversy, and as a consequence the number of species varies according to different publications. Although this can be due to the conservative characteristic of some morphological and genetic traits, like general shape and number of chromosomes, the scarce knowledge on several species is probably the main reason for this controversy. Also, some species have been discovered only recently, and from others we miss any information since they have been first described (mainly in pikas). We struggled with this difficulty during the work on this book, and decide to include a list of lagomorph species (Table 1). As a reference, we used the recent list published by Hoffmann and Smith (2005) in the “Mammals of the world” (Wilson and Reeder, 2005). However, to make an updated list, we include some significant published data (Friedmann and Daly 2004) and the contribu- tions and comments of some lagomorph specialist, namely Andrew Smith, John Litvaitis, Terrence Robinson, Andrew Smith, Franz Suchentrunk, and from the Mexican lagomorph association, AMCELA. We also include sum- mary information about the geographical range of all species and the current IUCN conservation status. Inevitably, this list still contains some incorrect information. However, a permanently updated lagomorph list will be pro- vided via the World Lagomorph Society (www.worldlagomorphsociety.org). 1 CIBIO, Centro de Investigaçaõ em Biodiversidade e Recursos Genéticos and Faculdade de Ciências, Universidade do Porto, Campus Agrário de Vairaõ 4485-661 – Vairaõ, Portugal 2 Institute of Wildlife Biology and Game Management, University of Natural Resources and Applied Life Sciences, Gregor-Mendel-Str.
