NF93-136 Chemical Spots, Stains and Discoloration of Home Furnishings

We live in a world of chemicals. Unfortunately, some of the characteristics that make household chemical products the most useful are the same qualities that lead to trouble when these products are carelessly handled. A chemical stain or spot is a serious kind of stain that is appearing with increasing frequency and is different from ordinary stains. This type of discoloration or color is caused by a variety of chemical ingredients contains in dozens of common household products. This NebFact discusses the different chemical spots, stains and discolorations that are found in your home furnishings.

RP97-362 File It Easy, Find It Fast: A Home Filing System

A home filing system makes important papers readily available when needed. If managed properly, the filing system can get older papers out of the way, making needed records more accessible. A well-organized filing system for your household can pay big dividends when it comes time to find an important paper you need NOW. There is no one best filing system for everyone; what works for you could be a disaster for someone else. Once set up, a filing system helps you to be a more effective and efficient financial manager and decision maker.

Crop, Native Vegetation, and Biofuels: Response of White- Tailed Deer to Changing Management Priorities

The expansion of the cellulosic biofuels industry throughout the United States has broad-scale implications for wildlife management on public and private lands. Knowledge is limited on the effects of reverting agriculture to native grass, and vice versa, on size of home range and habitat use of white-tailed deer (Odocoileus virginianus). We followed 68 radio-collared female deer from 1991 through 2004 that were residents of DeSoto National Wildlife Refuge (DNWR) in eastern Nebraska, USA. The refuge was undergoing conversion of vegetation out of row-crop agriculture and into native grass, forest, and emergent aquatic vegetation. Habitat in DNWR consisted of 30% crop in 1991 but removing crops to establish native grass and wetland habitat at DNWR resulted in a 44% reduction in crops by 2004. A decrease in the amount of crops on DNWR contributed to a decline in mean size of annual home range from 400 ha in 1991 to 200 ha in 2005 but percentage of crops in home ranges increased from 21% to 29%. Mean overlap for individuals was 77% between consecutive annual home ranges across 8 years, regardless of crop availability. Conversion of crop to native habitat will not likely result in home range abandonment but may impact disease transmission by increasing rates of contact between deer social groups that occupy adjacent areas. Future research on condition indices or changes in population parameters (e.g., recruitment) could be incorporated into the study design to assess impacts of habitat conversion for biofuel production.

The History of the German-Russian Colony in Lincoln

Standing at the corner of Tenth and O streets in the city of Lincoln, Nebraska, any week-day morning between 7:30 and 8 o'clock, you may see pass by you from ten to twenty women with little black woolen shawls on their heads. Ask any citizen who they are, and ninety-nine times in one hundred he will tell you they are "Russians" who live down on the bottoms, that they are going out into the offices and homes to wash and scrub and clean house, and that their husbands are street laborers or work for the railroad. He may then grow confidential and tell you that he "has no use for these people", that "they are only half human", and that he "would just as soon see the Chinese come here as those people". As a matter of fact the greater part of his information is incorrect, partly through race prejudice but chiefly through ignorance of their history. These people, of whom there are about 4,000 in the city (Including "beet fielders"), are Germans, not Russians: they are Teutons, not Slavs; they are Lutheran and Reformed, not Greek Catholics. To be sure they and their ancestors lived in Russia for over one hundred years and they came here directly from the realm of the Czar whoso bona fide citizens they were—but they never spoke the Russian language, never embraced the Greek religion, never intermarried with the Russians, and many of their children never saw a Russian until they left their native village for the new home in America. They despise being called "Russians" just as an Italian resents "Dago"; a Jew, "Sheeny"; and a German, "Dutchman". Ask them where they came from and most of the children and not a few of the grown people will say, "Germany". If you pursue your questioning as to what part of Germany, they will tell you "Saratov" or "Samara" - two governments in the eastern part of Russia on the lower course of the Volga river. The misconceptions concerning the desirability of these German-Russians as citizens arise from their unprogressiveness as compared with those Germans who come to us directly from the mother country. During their century's sojourn in Russia they have been out of the main current of civilization, a mere eddy in the stream of progress. They present a concrete example of arrested development, The characteristics which differentiate them from other Germans are not due to an inherent lack of capacity but to different environment. Notwithstanding this, the German- Russians have some admirable qualities. They bring us large stores of physical energy and an almost unlimited capacity for work. The majority of them are literate although the amount of their education is limited. They are thrifty and independent, almost never applying for public aid. They are law abiding, their chief offenses being those which are traceable to their communal life in Russia. They are extremely religious, all their social as well as spiritual life being bound up in the church which they support right royally. To be sure, the saloon gets their vote (the prohibition vote among them is increasing); but "was not the first miracle that Christ performed the turning of water into wine? If they would shut up the shows (theaters), they wouldn't need to shut up the saloons". The object of this paper is to give the historical setting in which the German-Russians have lived as one means to a better understanding and appreciation of them by our own citizens.

HOME RANGES AND MOVEMENTS OF COYOTES IN THE NORTHERN CHIHUAHUAN DESERT

The coyote (Canis latrans) is among the most studied animals in North America. Because of its adaptability and success as a predator, the coyote has flourished and is still expanding its range. Coyotes can now be found throughout most of North America and south into Central America (Voight and Berg 1987). Studies in recent years have been extensive to understand the interrelationships of prey and coyotes (Shelton and Klindt 1974, Beckoff and Wells 1981), as well as demographic relationships (Davis et al. 1975, Knowlton and Stoddart 1978, Mitchell 1979, Bowen 1981) and feeding strategies (Todd and Keith 1976, Andelt et al. 1987, MacCracken and Hansen 1987, Gese et al. 1988a). With the advance of radio telemetry, researchers have investigated lifestyle characteristics spatially with home ranges or temporally with movements in relation to habitat requirements. Researchers have studied home ranges of coyotes in various regions of the United States (Livaitis and Shaw 1980, Andelt 1981, Springer 1982, Pyrah 1984, Gese et al. 1988a) and Canada (Bowen 1982). Some studies of home range were separated by season (Ozoga and Harger 1966) or relation to nearby food sources (Danner and Smith 1980). Home range analysis in relation to social interactions of coyotes has been either neglected, overlooked, or avoided. Gese et al. (1988a) recognized a transient class of coyote by home range size. Coyote social systems are very complex and can vary by season or locality in addition to some reports of group or pack systems (Hamlin and Schweitzer 1979, Beckoff and Wells 1981, Bowen 1981, Gese et al. 1988b). Coyotes maintain communication with conspecifics through vocal and olfactory signals (Lehner 1987, Bowen and McTaggert Cowan 1980). Social interactions may be by far the most complex and least understood aspect related to coyote ecology. Coyote movements can be related to many factors including food, water, cover, and social interactions. Movements in relation to food sources are well documented (Fitch 1948, Todd and Keith 1976, Danner and Smith 1980) although reports on movements in relation to water have not been reported, probably because of limited research in desert situations. There has been some mention of coyotes' movements in relation to cover (Wells and Beckoff 1982). The objectives of this study were to delineate annual and seasonal home ranges, movements, and habitat use of coyotes in the northern Chihuahuan desert.
