Using Digital Images In The Study Of Fluctuating Asymmetry In The Spur-Thighed Tortoise Testudo Graeca, Gabriel Buica, Dan Cogalniceanu
Turkish Journal of Zoology
Fluctuating asymmetry has been proposed as a useful noninvasive tool for detecting the influence of the environment on body development. In the present study, we used digital images to estimate the fluctuating asymmetry of the plastron in an isolated Testudo graeca population in Dobrogea, Romania. We extracted data from the photos regarding the area, height, and width of 3 plastron scutes. A total of 155 adult tortoises analysed showed reduced variation in plastron asymmetry and no significant relationship was detected between fluctuating asymmetry and sex or body size. We suggest that fluctuating asymmetry may be an individual trait, with no …

Migration of susceptible individuals from untreated areas to populations that have developed insecticide resistance is one of the most important processes that can significantly delay or even prevent the development of resistance against insecticides. Fitness parameters of susceptible and resistant insect populations and changes in fitness following susceptible population migration have a crucial place in this process, as they determine the permanence and spread of susceptible alleles in the absence of insecticides. In this study, we investigated changes in resistance levels and fitness characteristics after introducing individuals from the ancestral susceptible strain in an equal ratio to a housefly (Musca …
