• This challenge to understanding the lifestyle of extinct animals is exemplified by the controversy over the feeding behavior of the Late Cretaceous theropod Tyrannosaurus rex ( 3 , 7 ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ - 17 ). (pnas.org)
  • Although predation and scavenging have often been suggested as distinct feeding behavior alternatives ( 3 , 7 ⇓ - 9 , 11 ⇓ ⇓ ⇓ ⇓ ⇓ - 17 ), these terms merit semantic clarification. (pnas.org)
  • In this study, predation is considered a subset of feeding behavior, by which any species kills what it eats. (pnas.org)
  • His research has included autopsying dead marine mammals, studying the feeding behavior of sharks, and trying to estimate shark population size. (angelfire.com)
  • Ancient diets can be readily reconstructed on the basis of the available evidence, although their derivation (e.g., predation or scavenging behavior) often remains elusive. (pnas.org)
  • At its core, aggressive behavior addresses the dog's need to increase distance from a perceived danger. (positively.com)
  • In most cases, the dog's intention is not so much to harm the threat as it is to change the threat's behavior by making it go away. (positively.com)
  • Although aggressive behavior is an effective way for dogs to control their environment, affect behavior in others, ensure priority access to resources, and achieve reproductive success, using the dog's supposed desire to be the 'alpha' to explain why dogs aggress does not do justice to what is really going on in the dog's mind. (positively.com)
  • Owners understandably want quick fixes for their dog's aggressive behavior because they worry about what damage their dog may do, but the 'quick fix' idea demeans a dog's emotional experience and is psychologically unachievable. (positively.com)
  • Because destructive behavior has many potential causes, a careful analysis of the dog's history and environment is necessary to help identify the cause of the problem so that effective behavior modification techniques can be recommended. (mspca.org)
  • Thus, anticipation of the owner's return or arrival increases the dog's anxiety level, and may result in destructive behavior to relieve the anxiety. (mspca.org)
  • One of the most daunting tasks of paleontology is inferring the behavior and feeding habits of extinct organisms. (pnas.org)
  • Dr. Douglas Long has been doing research on the ecological interactions, in particular the feeding habits and predatory behavior of great white sharks on marine mammals along the coast of central California for several years now. (angelfire.com)
  • Traditional ecotoxicology studies focus on the physical effects a chemical has on growth and reproduction, but this study highlights the need to evaluate behavior when assessing the effects of contaminants on wildlife populations. (phys.org)
  • Studies have shown that it is a systematic behavior in different populations of chimpanzees [ 8 ], which may occur either individually or cooperatively. (mdpi.com)
  • Helping an aggressive dog become more confident by teaching him to see a perceived threat or potential loss of a valued resource in a different light is the key to successfully changing the behavior. (positively.com)
  • Instead, this investigation will deal exclusively with the evolutionary history of the australopithecines: their anatomy, diet, ecology and behavior. (tolweb.org)
  • Fearful responses to thunderstorms and loud noises often involve escape attempts that result in destructive behavior. (mspca.org)
  • However, these normal behaviors can result in destruction of household property, which can become a serious and frustrating problem for owners. (mspca.org)
  • Even though it may look like the dog is 'behaving' better, continually suppressing aggressive behavior through punishment is very dangerous because every incident creates another negative experience for a dog that is already a ticking time bomb. (positively.com)
  • our study provides preliminary information or baseline characteristics on putative escape behavior of juvenile frogs to a mock heron attack. (phys.org)
  • In his book, Dying to Be Men , Dr. Will Courtenay describes the cultural influences of "masculinity" that lead men to reject many healthy behaviors, and simultaneously to gravitate to numerous unhealthy behaviors instead, which put them at risk of death, injury and disease. (psychcentral.com)
  • Oxytocin, dopamine and serotonin develop synapses each time they are released, strengthening any behavior patterns associated with feel-good sensations of relief. (psychcentral.com)
  • Stoesz says the 8-year-old's mother contacted camp workers several times about concerning behavior described by her daughter. (fox59.com)
  • But, he says, camp workers didn't follow protocols to handle the behavior or take steps to keep it from happening again. (fox59.com)
