  1. Birds and Dogs: Toward a Comparative Perspective on Odor Use and Detection

    Full-text: Available

    | Contributor(s):: Paola A. Prada, Kenneth G. Furton

    While canines are generally considered the gold standard for olfactory detection in many situations other animals provide alternatives and offer a unique opportunity to compare biological detection capabilities. Critical components in successfully studying biological detectors is not only...

  2. Understanding Animal Detection of Precursor Earthquake Sounds

    | Contributor(s):: Michael Garstang, Michael C. Kelley

    We use recent research to provide an explanation of how animals might detect earthquakes before they occur. While the intrinsic value of such warnings is immense, we show that the complexity of the process may result in inconsistent responses of animals to the possible precursor signal. Using the...

  3. Sniffing Out Cancer: Pina De Rosa & Adriana LaCorte at TEDxWilmington

    | Contributor(s):: Pina De Rosa, Adriana LaCorte

    Pina De Rosa and Adriana LaCorte describe, with great passion and intensity, their ongoing project -- making a documentary about the ability of dogs to identify, through scent, cancer BEFORE even the most modern technology. Their talk describes the beginning of the process, and features clips...

  4. Animal health surveillance for early detection of emerging infectious disease risks

    | Contributor(s):: Kate Elizabeth Sawford

    The global public health community is facing the challenge of emerging infectious diseases. Historically, the majority of events have originated in the animal population. This research investigates animal health surveillance for early detection of emerging infectious disease risks. A mobile...

  5. Detection of Verticillium dahliae in olive groves using canine detection units

    | Contributor(s):: Pons Anglad a, L., Calvo Torras, M. dels A.

    Verticillium wilt is one of the most significant agricultural diseases in the world, in view of the fact that not only does it affect olive groves but also a wide variety of fruit, vegetable and ornamental plants. Currently, the most efficient and economical method of control involves the use of...

  6. Olfactory discrimination and generalization of ammonium nitrate and structurally related odorants in Labrador retrievers

    | Contributor(s):: Lazarowski, L., Foster, M. L., Gruen, M. E., Sherman, B. L., Fish, R. E., Milgram, N. W., Dorman, D. C.

    A critical aspect of canine explosive detection involves the animal's ability respond to novel, untrained odors based on prior experience with training odors. In the current study, adult Labrador retrievers ( N=15) were initially trained to discriminate between a rewarded odor (vanillin) and an...

  7. Traits of drug and explosives detection in dogs of two breeds as evaluated by their handlers and trainers

    | Contributor(s):: Adamkiewicz, E., Jezierski, T., Walczak, M., Gorecka-Bruzda, A., Sobczynska, M., Prokopczyk, M., Ensminger, J.

    Police dogs handlers' and trainers' opinions on Labrador retrievers (n=87) and German shepherds (n=96) trained for drugs vs. explosives detection have been compared. As most important traits in both specialties the responders indicated: (1) willingness to sniff objects, (2) concentration...

  8. Behavioural, endocrine and cardiac autonomic responses to a model of startle in horses

    | Contributor(s):: Villas-Boas, J. D., Dias, D. P. M., Trigo, P. I., Almeida, N. A. dos S., Almeida, F. Q. de, Medeiros, M. A. de

    Startle is a fast response elicited by sudden acoustic, tactile or visual stimuli in a variety of animal species and in humans. The magnitude of startle response can be modulated by external and internal variables and can be a useful tool to study the sensory-motor integration in animals....

  9. African elephants ( Loxodonta africana) can detect TNT using olfaction: implications for biosensor application

    | Contributor(s):: Miller, A. K., Hensman, M. C., Hensman, S., Schultz, K., Reid, P., Shore, M., Brown, J., Furton, K. G., Lee, S.

    The impact of war on local wildlife can be devastating, the effects of which are often felt well beyond the terminus of the initial threat. In areas where wildlife experiences unrestricted movement through previously affected zones, residual, unexploded landmines present a significant and...

  10. The Scent of Disease: Human Body Odor Contains an Early Chemosensory Cue of Sickness

    | Contributor(s):: Mats J. Olsson, Johan N. Lundstrom, Bruce A. Kimball, Amy R. Gordon, Bianka Karshikoff, Nishteman Hosseini, Kimmo Sorjonen, Caroline Olgart Hoglund, Carmen Solares, Anne Soop, John Axelsson, Mats Lekander

    Observational studies have suggested that with time, some diseases result in a characteristic odor emanating from different sources on the body of a sick individual. Evolutionarily, however, it would be more advantageous if the innate immune response were detectable by healthy individuals as a...

  11. The Need for Judicial Restriction on the Use of Drug Detecting Canines

    | Contributor(s):: William R. Pomeroy

    The use of drug sniffing dogs to detect smuggled contraband began in September 1970 as a means of interdicting the flow of illegal drugs "through border ports and at major gateways" of this country.' Since then, the use of dogs to detect contraband has been expanded...

  12. State v. Rabb: Dog Sniffs Close to Home

    | Contributor(s):: Timothy C. Stone

    Sensory perception is an inextricable part of Fourth Amendment' jurisprudence. A policeman's sense of smell, for example, can create probable cause for a lawful search or seizure. A canine's sense of smell operates much like our own, except that its sensory...

    | Contributor(s):: Megan Parker

    Megan Parker talks about training dogs to work for conservation and preserve endangered species at a 2015 TEDx event in Jackson Hole.Megan is a pioneer in training dogs to work for conservation and preserve endangered species. She has been involved in dog training, obedience, and...

  14. Katz and Dogs: Canine Sniff Inspections and the Fourth Amendment

    | Contributor(s):: H. Paul Honsinger

    The canine nose, used by school officials and law enforcement officers to detect the presence of contraband on persons or in closed containers such as suitcases, lockers, and cars is becoming an increasingly frequent intruder in the lives of Americans.' Judicial analysis of...

  15. Reinforcement for Operational Mine Detection Rats

    | Contributor(s):: Amanda Mahoney, Christophe Cox, Bart Weetjens, Tess Tewelde, Tekimiti Gilbert, Amy Durgin, Alan Poling

    When using animals for the detection of landmines, handlers face challenges of when to reinforce indication responses, as the actual location of landmines in the field is unknown. Anti-Persoonsmijnen Ontmijnende Product Ontwikkeling(Anti-Personnel Landmine Detection Product Development or APOPO)...

  16. Research in Colombia on Explosives Detection by Rats

    | Contributor(s):: Luisa Fernando Mendez Pardo, Andres M. Perez-Acosta

  17. Network characteristics and development of social structure of agonistic behaviour in pigs across three repeated rehousing and mixing events

    | Contributor(s):: Buttner, K., Scheffler, K., Czycholl, I., Krieter, J.

    In commercial pig production, the mixing of unacquainted pigs is a standard procedure which leads to agonistic interactions with a wide range of individual pig behaviour. A reduction in these agonistic interactions positively affects animal health, welfare aspects and production parameters. With...
