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…
Al di là dell’opposizione tra “malessere concettuale” e “cattiva coscienza”. Sul disagio dell’antropologia contemporanea di fronte al maltrattamento …
2021
In this paper I propose a critical examination of the ways in which the intersections between violence, suffering and domination in some of the main new directions of the anthropological study of the relationships between humans and other animals, notably Ingold's approach, Descola’s theory of “schemas of the practice”, and multispecies ethnography. Apparently, and despite the emphasis given to the sentience and forms of agency of non-human animals, as well as to their being active coparticipants, together with humans, in the construction of social networks and the habitats that bind both, these intersections do not occupy a prominent place in these approaches, both from the point of view o…
A multispecies approach for modeling the ecological impact of urban development using landscape graphs
2013
International audience; Managing urban sprawl is become a major concern in the field of landscape ecology, since the land use changes involved by urban development may affect the ability of wildlife species to move across the landscape. In order to compare the ecological impact of several urban patterns, we aim at combining two complementary approaches: 1) Simulations of residential development from an initial land use map, using morphological rules of urban development (i.e. fractal vs non fractal) and accessibility constraints; 2) Models of ecological networks applied to a given natural habitat, using a landscape graphs-based approach. As landscape graphs are built according to the moving…
Fuzzy Systems Based on Multispecies PSO Method in Spatial Analysis
2012
We present a method by using the hierarchical cluster-based Multispecies particle swarm optimization to generate a fuzzy system of Takagi-Sugeno-Kang type encapsulated in a geographical information system considered as environmental decision support for spatial analysis. We consider a spatial area partitioned in subzones: the data measured in each subzone are used to extract a fuzzy rule set of above mentioned type. We adopt a similarity index (greater than a specific threshold) for comparing fuzzy systems generated for adjacent subzones.
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…
Multispecies coinfections and presence of antibiotics shape resistance and fitness costs in a pathogenic bacterium
2023
Increasing antimicrobial resistance (AMR) poses a challenge for treatment of bacterial diseases. In real life, bacterial infections are typically embedded within complex multispecies communities and influenced by the environment, which can shape costs and benefits of AMR. However, knowledge of such interactions and their implications for AMR in vivo is limited. To address this knowledge gap, we investigated fitness-related traits of a pathogenic bacterium (Flavobacterium columnare) in its fish host, capturing the effects of bacterial antibiotic resistance, coinfections between bacterial strains and metazoan parasites (fluke Diplostomum pseudospathaceum) and antibiotic exposure. We quantifie…
Developing response-ability in human-wasp encounters
2023
Learning to live with unloved others is crucial in the ecological crisis. Unloved wasps are feared and disliked for their sting. Understanding of their ecological importance is increasing, however. Human-wasp encounters are changing with environmental changes, and strategies for multispecies cohabitation are needed. This multispecies study highlights features of wasp biology affecting human-wasp encounters and analyzes how conflicted human-wasp relations could be mitigated. The geographical focus is Finland, in the Northern boreal region. Biological analysis specified spatiotemporal aspects affecting human-wasp encounters: human and wasp habitats and preferences overlap ubiquitously. From a…
