(The white footed mouse is sometimes commonly called a deermouse and viceversa, but it is a seperate species, Peromyscus leucopus). The photos on this page show an adult deermouse (dark brown) compared to a fancy mouse (black eyed white American type). Most striking is the difference of the shape of the head, eye size, and the seemingly largish head on a small body proportions of the deermouse compared to that of the fancy mouse. Deermice (Peromyscus maniculatus) and Fancy mice (Mus musculus domesticus) can not interbreed; in fact, the fancy mouse is much more closely related to the fancy rat (Rattus norvegicus)! Both are of the family Muridea and subfamily, Murine. The Deermouse, while in the same family, is in a different subfamily, Sigmodontinae. Nonetheless, I have found that my fancy mice and deermice readily accept each other as cage mates, even as adults. My fancy mice have even on occasion foster raised orphaned deermice with success. A Word of Caution: Deermice can carry Hantavirus, which can affect humans; infection with Hanta requires hospitalization and ventilation within 24 hours and can be deadly.

  • Biology Assessment Plan Spring 2019
    Biological Sciences Department 1 Biology Assessment Plan Spring 2019 Task: Revise the Biology Program Assessment plans with the goal of developing a sustainable continuous improvement plan. In order to revise the program assessment plan, we have been asked by the university assessment committee to revise our Students Learning Outcomes (SLOs) and Program Learning Outcomes (PLOs). Proposed revisions Approach: A large community of biology educators have converged on a set of core biological concepts with five core concepts that all biology majors should master by graduation, namely 1) evolution; 2) structure and function; 3) information flow, exchange, and storage; 4) pathways and transformations of energy and matter; and (5) systems (Vision and Change, AAAS, 2011). Aligning our student learning and program goals with Vision and Change (V&C) provides many advantages. For example, the V&C community has recently published a programmatic assessment to measure student understanding of vision and change core concepts across general biology programs (Couch et al. 2019). They have also carefully outlined student learning conceptual elements (see Appendix A). Using the proposed assessment will allow us to compare our student learning profiles to those of similar institutions across the country. Revised Student Learning Objectives SLO 1. Students will demonstrate an understanding of core concepts spanning scales from molecules to ecosystems, by analyzing biological scenarios and data from scientific studies. Students will correctly identify and explain the core biological concepts involved relative to: biological evolution, structure and function, information flow, exchange, and storage, the pathways and transformations of energy and matter, and biological systems. More detailed statements of the conceptual elements students need to master are presented in appendix A.

  • Keeping Rats As Pets
    Association of Pet Behaviour Counsellors www.apbc.org.uk E: [email protected] AN INTRODUCTION TO Keeping Rats as Pets Cara Wilson BSc (Hons) PGDE Introduction If you are looking for a pet that is friendly, entertaining and social, then rats are a great choice for all ages. Despite many people having a predisposed phobia of them, once you have met rats, even the most reluctant of people find it hard to resist their charm. The following article examines some of the considerations of keeping rats as pets including the cost of keeping rats, common health problems that may be encountered and how understanding a rat’s natural behaviour can ensure better care is provided. Firstly, rats are highly entertaining (authors own observations). If males from other males whereas females and many an hour can be spent are housed nearby, these males tend to display more avoidance observing their interesting may begin fighting over the potential behaviours. However, these displays behaviours. Each individual rat has mate (Taylor, 1975). Both sexes can of aggression will often depend on a distinctive personality that cannot be neutered therefore preventing the social status of the individual fail to entertain even the hardest of unwanted litters in mixed groups. in question (Hurst et al., 1996).

  • DOMESTIC RATS and MICE Rodents Expose Humans to Dangerous
    DOMESTIC RATS AND MICE Rodents expose humans to dangerous pathogens that have public health significance. Rodents can infect humans directly with diseases such as hantavirus, ratbite fever, lymphocytic choriomeningitis and leptospirosis. They may also serve as reservoirs for diseases transmitted by ectoparasites, such as plague, murine typhus and Lyme disease. This chapter deals primarily with domestic, or commensal, rats and mice. Domestic rats and mice are three members of the rodent family Muridae, the Old World rats and mice, which were introduced into North America in the 18th century. They are the Norway rat (Rattus norvegicus), the roof rat (Rattus rattus) and the house mouse (Mus musculus). Norway rats occur sporadically in some of the larger cities in New Mexico, as well as some agricultural areas. Mountain ranges as well as sparsely populated semi­desert serve as barriers to continuous infestation. The roof rat is generally found only in the southern Rio Grande Valley, although one specimen was collected in Santa Fe. The house mouse is widespread in New Mexico, occurring in houses, barns and outbuildings in both urban and rural areas. I. IMPORTANCE Commensal rodents are hosts to a variety of pathogens that can infect humans, the most important of which is plague. Worldwide, most human plague cases result from bites of the rat flea, Xenopsylla cheopis, during epizootics among Rattus spp. In New Mexico, the commensal rodent species have never been found infected with plague; here, the disease is prevalent among wild rodents (especially ground squirrels) and their fleas. Commensal rodents consume and contaminate foodstuffs and animal feed.

  • I Offer My Power in the Service of Love
    Kathy High I offer my power in the service of Love n this talk I would like to present an older project of mine that situates my pieces in INGBK ‘s Becomig Animal/Becoming Human exhibition. This project was an installation entitled Embracing Animal commissioned by Nato Thom- son, curator, for the Becoming Animal: Contemporary Art in the Animal Kingdom exhibition at MASS MoCA (Massachusetts Museum of Contemporary Art), in 2005-2006, North Adams, Massachusetts. In Nato Thompson’s catalogue essay for the exhibition, he used a quotation by Giorgio Agamben: “The first task of the researcher observing an animal is to recognize the carriers of significance which constitute its environment.” (exhibition catalogue, p.10) My mul- timedia installation, Embracing Animal, appreciated this need for observation in its recreation of an ersatz research laboratory with 3 transgenic lab rats who lived in the exhibition for ten months.

  • The 2006 Fancy Rat Import
    The 2006 Fancy Rat Import The origin of Fancy Rats in South Africa The origin of pet rats in South Africa is unknown but it is believed that they may have come from laboratory stock. In the 1950’s there were only PEW rats available with Agouti, Black, Berkshire and Hooded varieties appearing before the 1980’s. In the late 1980’s, Cape slate was first seen in pet stores in Cape Town and Sable Siamese in the early 1990’s in Gauteng. In 2005 Liezel Hatting of Moonstones Rattery imported 18 fancy rats from the USA. Connie Perez collected the rats and organized the import from the USA side. The import included American, British as well as Australian varieties. In January 2006 the rats were released from quarantine. Liezel and Annalie (Combrink) Prinsloo from Aurora rattery bred these lines intensively and offspring were sent to Wheatfields, Jackalhead and Runebound rattery. Several other ratteries joined in the years to follow. Some of these lines are still being bred by SARBU ratteries today. Annalie Prinsloo wrote the South African breeding standards for fancy rats in 2008 which are used by SARBU and SAFRA breeders today: http://ronelrat.wixsite.com/ptarattery/rat-varieties-genetics On three occasions rats from the import were bred by pet owners and introduced to local pet and feeder lines: 2010 - Standard eared black husky (Roan). They were cross bred to Sable Siamese. These are common in feeder lines in the Free state, Gauteng, KZN and Mpumalanga today 2014 - Agouti Dumbo husky. These rats were never bred in large numbers but were eventually bred to black hooded and PEW rats.
