The article “Why pace? The influence of social, housing, management, life history, and demographic characteristics on locomotor stereotypy in zoo elephants” written by Greco et al. is about the behaviors of captive elephants in American zoos. This study was conducted in order to determine what factors of captivity within zoos contribute to the development of non-natural behaviors, known as stereotypical behaviors, in captive elephants. To determine these, the researchers developed a classification system with four forms: stationary full body movements, locomotor movements, oral behaviors, and self-directed behaviors. They then filmed at least ten hours of footage of each elephant from 39 different American zoos and added that footage to film …show more content…

Once the data was collected, the researchers conducted various statistical test to determine how the behaviors differed with each individual variable. They found that full body stereotypical behaviors and locomotor stereotypical behaviors were respectively the first and second most prevalent and frequently preformed forms of stereotypical behaviors. They also found that both the amount of time each elephant spent housed alone or indoors and the number of social groups that each elephant was a member of increased the odds that the elephant developed a locomotor behavior, a behavior involving movement, increased as well. They concluded that the amount of time spent alone and the number of social groups an elephant was a member of likely influenced the odds of developing a locomotor stereotypical behavior in elephants because of frustration from not being able to control their own social interactions or from the anticipation of positive events. They also concluded that the amount of time housed inside likely influenced the development of locomotor stereotypical behaviors because indoor environments are less complex and less …show more content…

The main shortcoming of this article was that there were so many variables studied that the researchers had to make many hypotheses including each of these variables. They presented these hypotheses in a table, but the reader still had to do a considerable amount of jumping between pages to be reminded of what their hypotheses were. Another downfall of having multiple variables present is that the results may have been affected by more than just one variable at a time. This could be a possible error of this study, however, there is no conceivable alternative way to eliminate multiple variables. Human error could have also affected the results since multiple people were used to record the behaviors seen and there may have been slight variations in each person’s understanding of the behaviors studied, although this again is virtually unavoidable. For future research, I believe that, like the article suggested, there needs to be studies done to determine whether or not changed management of elephants to avoid some of these risk factors of stereotypical behavior will result in a decrease of stereotypical behaviors in captive
