Rodent

In this novel for teens, Isabelle knows all about shouldering responsibility: she looks after her younger siblings because their mother is often drunk or absent. School is a nightmare, but one teacher seems to understand that Isabelle has talent to spare.

The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

By far, the most widely used subjects in psychological and biological research today are rodents. Although rats and mice comprise the largest group of animals used in research, there are over 2,000 species and 27 families of rodents, living all over the world (except Antarctica) and thriving in many different habitat types. The vast environmental diversity that rodents face has led to numerous adaptations for communication, including vocalizing and hearing in both the sonic and ultrasonic ranges, effectively communicating in the open air and underground, and using vocalizations for coordinating sexual behavior, for mother-pup interactions, and for signaling an alarming situation to the group. Some rodent species have even developed foot drumming behaviors for communication. Comparative studies from around the globe, using both field and laboratory methodologies, reveal the vast differences in acoustic communication behavior across many rodent species. Some rodents are amenable to training and have been domesticated and bred purely for research purposes. Since the early 1900s, rats and mice have been indispensable to research programs around the world. Thus, much of what we know about hearing and vocalizations in rodents come from these two species tested in the laboratory. The sequencing of the mouse genome in 2002, followed by the rat genome in 2004, only increased the utility of these animals as research subjects since genetically engineered strains mimicking human diseases and disorders could be developed more easily. In the laboratory, rats and mice are used as models for human communication and hearing disorders and are involved in studies on hearing loss and prevention, hormones, and auditory plasticity, to name a few. We know that certain strains of mice retain hearing better than others throughout their lifespan, and about the genes involved in those differences. We know about the effects of noise, hormones, sex, aging, and circadian rhythms on hearing in mice and other rodents. We also know about normal hearing in many families of rodents, including the perception of simple and complex stimuli and the anatomy and physiology of hearing and sound localization. The importance of acoustic communication to these animals, as well as the significance of these mammals to biomedical research, are summarized in the chapters.

A valuable resource for the latest research on rodents, highlighting links across palaeontology, developmental biology, functional morphology, phylogenetics and biomechanics.

Stereotaxic neurosurgery in rodents is used by a variety of people working at research laboratories (research staff, technicians, students at animal facilities...). The present handbook presents all the steps necessary to complete a stereotaxic neurosurgery protocol in accordance with current animal welfare guidelines. This book will guide surgeons step by step, from anesthesia to the post-surgery recovery procedures, including asepsis of the surgical tools and surgical zone, analgesia, correctly identifying the reference points on the skull and brain targets, etc. In keeping with the current international trends, the authors above all focus on the following points: the consideration of pain and how to best treat it depending on the type of surgery; and ensuring asepsis. This book will serve as an important reference work and valuable guidebook for the scientific community.

Scientists from both academia and industry in many countries have closely cooperated to arrive at a consensus on the descriptions of all the types of tumour and preneoplastic lesions encountered in laboratory mice. The series of fascicles should provide information and guidelines especially adapted for international use in practical toxicologic pathology. Images showing the typical appearance of the discussed lesions and references to the most recently published papers complete the information presented here.

The most numerous of the world's invasive species, rodent pests have a devastating impact on agriculture, food, health and the environment. In the last two decades, the science and practice of rodent control has faced new legislation on rodenticides, the pests' increasing resistance to chemical control and the impact on non-target species, bringing a new dimension to this updated 2nd edition and making essential reading for all those involved in rodent pest control, including researchers, conservationists, practitioners and public health specialists.

Using the most well-studied behavioral analyses of animal subjects to promote a better understanding of the effects of disease and the effects of new therapeutic treatments on human cognition, Methods of Behavior Analysis in Neuroscience provides a reference manual for molecular and cellular research scientists in both academia and the pharmaceutic
