Centro de Estudios Avanzados en Ecología y Biodiversidad (CASEB). email: [email protected] ABSTRACT This work analyses the relationship between human beings and their environment taking into consideration the adjustment and eventual invasion of rabbits in Chile. It argues that in the long run, human actions have unsuspected effects upon the environment. In fact rabbits were seen initially as an opportunity for economic development because of the exploitation of their meat and skin. Later, rabbits became a plague in different areas of Central Chile, Tierra del Fuego and Juan Fernández islands, which was difficult to control. Over the years rabbits became unwelcome guests in Chile. Key words: Environmental History, biological invasions, European rabbit, ecology and environment. RESUMEN Este trabajo analiza las relaciones entre los seres humanos y su ambiente, a partir de la historia de la aclimatación y posterior invasión de conejos en Chile, constatando que, en el largo plazo, las acciones humanas tienen efectos e impactos insospechados sobre el medio natural. En efecto, si bien inicialmente los conejos fueron vistos como una oportunidad de desarrollo económico a partir del aprovechamiento de su piel y su carne, pronto esta especie se convirtió en una plaga difícil de controlar en diversas regiones del país, como Chile central, Tierra del Fuego e islas Juan Fernández. -

DIRECT ANALYSIS OF HOPS BY LEAF SPRAY AND PAPER SPRAY MASS SPECTROMETRY Kari Blain, M.S. Western Michigan University, 2012 The objective of this research is to develop a new and innovative method of hops analysis, which is much faster than standard testing methods, as well as reduce the amount of consumables and solvent used. A detailed discussion on the development of an ambient ionization mass spectrometry method called paper spray (PS-MS) and leaf spray (LS-MS) mass spectrometry will be presented. This research investigates the use of PS-MS and LS-MS techniques to determine the α- and β- acids present in hops. PS-MS and LS-MS provide a fast way to analyze hops samples by delivering data as rapidly as a UV-Vis measurement while providing information similar to lengthy liquid chromatographic separations. The preliminary results shown here indicate that PS-MS could be used to determine cohumulone and α/β ratios. -
Mouse Breeding Colony Management 1. Mouse Reproduction A. General Mouse Information I. the Average Mouse Lives Approximately
Mouse Breeding Colony Management 1. Mouse Reproduction A. General Mouse Information i. The average mouse lives approximately 2.5 years; however, the reproductive life span of mice is significantly shorter at 7-8 months. ii. Most mice reach sexual maturity (males and females) at 4-7 weeks of age. Younger mice generally produce smaller litters and therefore are not typically mated until they reach 6-8 weeks, of age. Mice that have been housed alone or in same-sex pairs will usually not breed successfully if they are older than 6-8 months. iii. The mouse estrous cycle is 4-5 days in length. Mice cycle continuously throughout the year (non-seasonal breeders). Female mice are only receptive to males when they are in estrus. Mating typically occurs at night (lights off). Ovulation occurs 8-12 hours after the onset of estrous. iv. If fertilization occurs, fetuses can be palpated by day 14. v. Gestation in mice is typically 19-21 days (strain dependent). vi. Parturition in mice may last 1-3 hours and frequently occurs at night. Females will go into estrus within 24 hours of parturition and are sexually receptive during this time. vii. Litter size varies among strains, but averages 4-12 pups. Inbred mice tend to have smaller litters than outbred mice. viii. Mice are typically weaned at 21-28 days or at 10g of body weight. The Purdue Animal Care and Use Committee requires that mouse pups be weaned at 21 days unless PACUC approval is given on an approved animal use protocol. See Policy attached. -

The Wild Rabbit: Plague, Polices and Pestilence in England and Wales, 1931–1955
The wild rabbit: plague, polices and pestilence in England and Wales, 1931–1955 by John Martin Abstract Since the eighteenth century the rabbit has occupied an ambivalent position in the countryside. Not only were they of sporting value but they were also valued for their meat and pelt. Attitudes to the rabbit altered though over the first half of the century, and this paper traces their redefinition as vermin. By the 1930s, it was appreciated that wild rabbits were Britain’s most serious vertebrate pest of cereal crops and grassland and that their numbers were having a significant effect on agricultural output. Government took steps to destroy rabbits from 1938 and launched campaigns against them during wartime, when rabbit was once again a form of meat. Thereafter government attitudes to the rabbit hardened, but it was not until the mid-1950s that pestilence in the form of a deadly virus, myxomatosis, precipitated an unprecedented decline in their population. The unprecedented decline in the European rabbit Oryctolagus( cuniculus) in the mid- twentieth century is one of the most remarkable ecological changes to have taken place in Britain. Following the introduction of myxomatosis into Britain in September 1953 at Bough Beech near Edenbridge in Kent, mortality rates in excess of 99.9 per cent were recorded in a number of affected areas.1 Indeed, in December 1954, the highly respected naturalist Robin Lockley speculated that 1955 would constitute ‘zero hour for the rabbit’, with numbers being lower by the end of the year than at any time since the eleventh century.2 In spite of the rapid increases in output and productivity which British agriculture experienced in the post-myxomatosis era, the importance of the disease as a causal factor in raising agricultural output has been largely ignored by agricultural historians.3 The academic neglect of the rabbit as a factor influencing productivity is even more apparent in respect of the pre-myxomatosis era, particularly the period before the Second World War. -
Rabbits and Guinea Pigs
Module 13 : Rabbits and Guinea Pigs By the end of this module, you will know: The different breeds of rabbits and guinea pigs The expected lifespan of each breed The age rabbits and guinea pigs are considered elderly How to care for young and elderly rabbits and guinea pigs The nutrition requirements Understanding their behavioral traits The type of hay best suited for younger rabbits 13.1: Breeds of Rabbits There are hundreds of different breeds of rabbits, all of which originate from different parts of the world. Each of them can be fitted into groups. Shorthaired, longhaired, fancy breeds, fur and Rex breeds. Among the fancy breeds of rabbits, there are Himalayan Flemish Giant Belgian hare French Angora English Spot There’s also the lop-eared rabbit, which there are a few types of. Each of these has large and long ears, which lop over their face, which is where their name comes from. An English lop is more distinct as it has the largest ears. A cashmere lop rabbit has the distinct long ears, but it’s also got the longest hair. A dwarf lop rabbit has the shortest of hairs, and therefore the most manageable in terms of the amount of grooming they require. The other two types of breeds are Fur breeds Rex Breeds All breeds of rabbits make for great pets. They are intelligent, and can be trained much in the same way you can litter-train a cat. Longhaired rabbits take more care than shorthaired ones, as they need grooming daily, to prevent their coats from matting. -

How to Read a Pet Food Label
How to read a pet food label It is important that you understand exactly what it is you are buying when you go to purchase a food to feed your pet. The pet food label: key information • Ingredient listing: Ingredients are the delivery vehicles • Obtaining the actual nutrient content from the for nutrients and are listed on a pet food label in manufacturer is a better way to evaluate products descending order by weight • The nutritional adequacy statement: This portion of the • Ingredients such as chicken, beef or lamb contain more label verifi es that the food provides complete and balanced than 50% water. The high water content makes them nutrition for growing animals, pregnant and nursing mothers, weigh more than dry ingredients such as grains, meat/ or adults – or it might say the product is nutritionally poultry meals, minerals and vitamins, so they are listed fi rst adequate for all of these groups (“all lifestages”) • The guaranteed analysis: The guaranteed analysis is • Caution should be exercised when considering foods designed to provide consumers with nutrient information intended for “all lifestages.” They may contain excessive about the pet foods they purchase.
