| Resumo: | Color patterns in animals are related to different selective pressures that species are subject to. Camouflage is one of the most important and has high efficiency in defending prey against a predator. One of an organisms' camouflage strategies is the ability to change their coloring, in addition to the structure of their bodies, to resemble the background environment in which they live, making their detection by predators more difficult. Camouflage can be broken through the memorization of characteristics that help in detecting an animal, which results in the formation of a search image. One way to create a search image is exposing subjects to field situations and coexistence with animals. Field practices play a fundamental role for students in the biological field, providing contact with the object of study, observation techniques and data collection. However the Covid-19 pandemic made the teaching process remote for two years, taking away the opportunity of countless students to undertake field trips. Therefore, the objective of this study was to evaluate the impact that the Covid-19 pandemic may have had on search image formation of undergraduate students. To this end, a virtual experiment was applied to thirty-two undergrad students from the Biological Sciences and Ecology courses, to evaluate the performances of two separated groups (those who had in-person field courses and those who had field courses in the remote period) on the detection of camouflaged animals. On a computer, four images of natural scenes were presented to the participating students, with only one of these images presenting a camouflaged animal. Participants had to detect which of these images presented the animal, within a maximum time of one minute per attempt, with a total of 60 attempts. The experimental subjects also answered a questionnaire about the experiences they acquired throughout their lives. Results did not show significance differences between the two groups, when evaluating the number of correct answers and response time in the attempts. In conclusion, the remote teaching modality, adopted during the COVID-19 pandemic, appears not to have influenced the formation of a search image for undergraduate students. |
