When frightened, ostriches instinctively bury their heads in the sand in the hopes that trouble will pass them by -- or so the legend goes. In reality, ostriches don't bury their heads in the sand to avoid danger. Not only would they be unable to breathe, but…
While the ostrich might look like an avian punch line, it's actually a nutritious source of red meat. Why do ostriches produce meat that's more like that of a cow than a chicken?
A large, flightless bird that lives in the dry grasslands of Africa, the ostrich is raised for its feathers and skin in South Africa, Egypt and California. Ostriches form the single remaining species in an ancient, primitive order of birds.
Wolves are some of the world's most charismatic and controversial animals, capturing the imaginations of their friends and foes alike. Highly intelligent and adaptable, they hunt and play together in close-knit packs, sometimes roaming over hundreds of square…
Artificial intelligence. Autonomous mental development by robots and animals
This article summarizes anatomical, neurophysiological, pharmacological, and brain imaging studies in humans and animals that have provided insights into the neural circuitry and neurotransmitter mechanisms controlling the lower urinary tract. The functions of…
Pheromones and Reproduction in Mammals reviews current research findings on the role of pheromones in mammalian reproduction. Drawing on both quantitative laboratory studies and selected observational field studies, the book explores how animals actively deplo…
Indiscriminate voiding of excreta by cattle contributes to greenhouse gas (GHG) emissions and soil and water contamination<sup>1</sup><sup>,</sup><sup>2</sup>. Emissions are higher in animal-friendly husbandry offering cattle more space<sup>2</sup> - a trade-o…
The use of urine marking in the scavenging behavior of the red fox (Vulpes vulpes)
Mammalian Olfaction, Reproductive Processes, and Behavior presents the conceptual, methodological, and empirical advances in the study of the complex interactions between nasal chemoreception, sexual behavior, and endocrine function in mammals. It focuses on t…
A Northern Pocket Gopher can dig an amazing half a metre of tunnel through compacted clay soil in just 15 minutes. North American Beavers, along with humans, are the only mammals whose impact on their environment is so massive that it can be clearly seen with…
Presents an illustrated guide to mammals, from hamsters and dormice to horses and asses, covering terrestrial and arboreal animals with key facts about behavior, habitat, physical characteristics, distribution, natural predators and prey, relatives, life cycle…
Could a porcupine make a good pet? Do they ever stick themselves or other porcupines with their quills? In this latest addition to the Animal Answer Guide series, we learn about these mysterious animals’ "pincushion defense," along with the following facts:• P…
These results indicate that in the anesthetized rat activation of urethral afferents by urethral perfusion can modulate the micturition reflex. Thus in patients with stress urinary incontinence, leakage of urine into the proximal urethra may stimulate urethral…
During micturition, according to the concept of Blok, Holstege, and colleagues ([1997] Neurosci. Lett. 233:109-112), the pontine micturition center (PMC) elicits bladder contraction by way of direct excitation of the parasympathetic bladder motoneurons. At the…
Micturition is a spino-bulbo-spinal reflex. The bulbospinal part of this reflex is formed by the projections from the M-region, also called the pontine micturition center or Barrington's nucleus, to the preganglionic parasympathetic motoneurons in the sacral c…
1. Reflexes to sacral parasympathetic neurones were studied by electrophysiological techniques in decerebrate, in chloralose-anaesthetized, and in chronic spinal cats.2. Excitatory reflexes from pelvic nerve and sacral somatic afferent nerve fibres were presen…
We have investigated with light and electron microscope immunocytochemistry the aminergic and peptidergic innervation of Onuf's nucleus in adult baboons. This nucleus, located in the ventrolateral part of the sacral spinal cord (S2 and S3), is considered to co…
