MINNESOTA MUSTELIDS Young
By Blane Klemek MINNESOTA MUSTELIDS Young Naturalists the Slinky,Stinky Weasel family ave you ever heard anyone call somebody a weasel? If you have, then you might think Hthat being called a weasel is bad. But weasels are good hunters, and they are cunning, curious, strong, and fierce. Weasels and their relatives are mammals. They belong to the order Carnivora (meat eaters) and the family Mustelidae, also known as the weasel family or mustelids. Mustela means weasel in Latin. With 65 species, mustelids are the largest family of carnivores in the world. Eight mustelid species currently make their homes in Minnesota: short-tailed weasel, long-tailed weasel, least weasel, mink, American marten, OTTERS BY DANIEL J.

Respiratory Turbinates of Canids and Felids: a Quantitative Comparison
J. Zool., Lond. (2004) 264, 281–293 C 2004 The Zoological Society of London Printed in the United Kingdom DOI:10.1017/S0952836904005771 Respiratory turbinates of canids and felids: a quantitative comparison Blaire Van Valkenburgh1*, Jessica Theodor 2, Anthony Friscia1, Ari Pollack1 and Timothy Rowe3 1 Department of Ecology and Evolutionary Biology, University of California, Los Angeles, CA 90095-1606, U.S.A. 2 Department of Geology, Illinois State Museum, 1011 East Ash Street, Springfield, IL 62703, U.S.A. 3 Department of Geological Sciences, University of Texas, Austin, TX 78712, U.S.A. (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. -

They are non- Florida Status: Endangered migratory residents of freshwater to brackish marshes. The Cape Sable seaside sparrow has the distinction of being the Recovery Plan Status: Revision (May 18, 1999) last new bird species described in the continental United Geographic Coverage: Rangewide States prior to its reclassification to subspecies status. The restricted range of the Cape Sable seaside sparrow led to its initial listing in 1969. Changes in habitat that have Figure 1. County distribution of the Cape Sable seaside sparrrow. occurred as a result of changes in the distribution, timing, and quantity of water flows in South Florida, continue to threaten the subspecies with extinction. This account represents a revision of the existing recovery plan for the Cape Sable seaside sparrow (FWS 1983). Description The Cape Sable seaside sparrow is a medium-sized sparrow, 13 to 14 cm in length (Werner 1975). Of all the seaside sparrows, it is the lightest in color (Curnutt 1996). The dorsal surface is dark olive-grey and the tail and wings are olive- brown (Werner 1975). Adult birds are light grey to white ventrally, with dark olive grey streaks on the breast and sides. The throat is white with a dark olive-grey or black whisker on each side. Above the whisker is a white line along the lower jaw. A grey ear patch outlined by a dark line sits behind each eye. -

OTARIIDAE AND PHOCIDAE DEFINITION AND GENERAL DESCRIPTION Pinnipeds are aquatic carnivores. They differ from other mammals in their streamlined shape, reduction of pinnae and adaptation of both fore and hind feet to form flippers. In the skull, the orbits are enlarged, the lacrimal bones are absent or indistinct and there are never more than three upper and two lower incisors. The cheek teeth are nearly homodont and some conditions of the ear that are very distinctive (Repenning 1972). Both superfamilies of pinnipeds, Phocoidea and Otarioidea, are represented in Australian waters by a number of species (Table 56.1). The various superfamilies and families may be distinguished by important and/or easily observed characters (Table 56.2). King (1983b) provided more detailed lists and references. These and other differences between the above two groups are not regarded as being of great significance, especially as an undoubted fur seal (Australian Fur-seal Arctocephalus pusillus) is as big as some of the sea lions and has some characters of the skull, teeth and behaviour which are rather more like sea lions (Repenning, Peterson & Hubbs 1971; Warneke & Shaughnessy 1985). The Phocoidea includes the single Family Phocidae – the ‘true seals’, distinguished from the Otariidae by the absence of a pinna and by the position of the hind flippers (Fig. -
