Differences in boldness are repeatable and heritable in a long-lived marine predator
Animal personalities, composed of axes of consistent individual behaviors, are widely reported and can have important fitness consequences. However, despite theoretical predictions that life-history trade-offs may cause and maintain personality differences, our understanding of the evolutionary ecology of personality remains poor, especially in long-lived species where trade-offs and senescence...
متن کاملFood provisioning increases the risk of injury in a long-lived marine top predator
Food provisioning of wildlife is a major concern for management and conservation agencies worldwide because it encourages unnatural behaviours in wild animals and increases each individual's risk for injury and death. Here we investigate the contributing factors and potential fitness consequences of a recent increase in the frequency of human interactions with common bottlenose dolphins (Tursio...
متن کاملRepeatable and heritable behavioural variation in a wild cooperative breeder
Quantifying consistent differences in behaviour among individuals is vital to understanding the ecological and evolutionary significance of animal personality. To quantify personality, the phenotypic variation of a behavioural trait is partitioned to assess how it varies among individuals, which is also known as repeatability. If pedigree data are available, the phenotypic variation can then be...
متن کاملtragic contradictions: a comparative study of characterization in eugene o’neill’s long day’s journey into night and mahmud dowlatabadi’s tangna
در طی چند دهه ی اخیر، مفهوم «تراژدی» و «قهرمان تراژدی» توجهی روزافرون را تقریباً در تمام حوزه های نقد ادبی به خود معطوف کرده است. برخی نظیر ارسطو، نیچه، و آرتور میلر به بازخوانی آن پرداخته و برخی دیگر نظیر سارتر، استریندبرگ، یوجین اُنیل، برتولت برشت، و آنتونین آرتود به افزودن ابعاد نوینی به این مبحث همت گماشته اند. آنچه قهرمان تراژدی مدرن را از مفهوم کلاسیک آن متمایز می کند نه لغزش تراژیک متداول ...
Effects of age and reproductive status on individual foraging site fidelity in a long-lived marine predator
Individual foraging specializations, where individuals use a small component of the population niche width, are widespread in nature with important ecological and evolutionary implications. In long-lived animals, foraging ability develops with age, but we know little about the ontogeny of individuality in foraging. Here we use precision global positioning system (GPS) loggers to examine how ind...
