Diurnal timing of nonmigratory movement by birds: the importance of foraging spatial scales
2020
Timing of activity can reveal an organism's efforts to optimize foraging either by minimizing energy loss through passive movement or by maximizing energetic gain through foraging. Here, we assess whether signals of either of these strategies are detectable in the timing of activity of daily, local movements by birds. We compare the similarities of timing of movement activity among species using six temporal variables: start of activity relative to sunrise, end of activity relative to sunset, relative speed at midday, number of movement bouts, bout duration and proportion of active daytime hours. We test for the influence of flight mode and foraging habitat on the timing of movement activit…
Umani e animali nell’antropologia socioculturale contemporanea
2022
In the chapter, I show the connection between the ways in which the nineteenth-twentieth century sociocultural anthropologists became interested in the study of human-animal relationships and the dominant conceptions about the relationship between humanity and animality in philosophical and scientific thought of these two centuries. Till the last part of the twentieth century non-human animals were considered by anthropologists mainly as material and/or symbolic resources for the reproduction of humans and their social orders. This view paralleled the dominant vision in Western modern philosophical and scientific thought in which non-human animals were assimilated to mindless machines belon…
