Typologie des enclos dans les forêts du Châtillonnais (Côte d'Or)
2014
Alors que de nombreux parcellaires sous forêts sont révélés par le Lidar et le plus souvent attribués à la période gallo-romaine, les parcellaires du Châtillonnais étudiés à travers les habitats par différents moyens ( relevés GPS, indices Lidar et prospections pédestres) donnent des indices d'une occupation plus ancienne. Ces habitats appréhendés par les structures externes en élévation se répartissent en groupes distincts par la forme de l'enclos qui les entourent, la présence ou non d'une construction en pierres. Pour une partie des enclos de forme quadrangulaire, la spécificité du matériel recueilli oriente vers une fonction cultuelle.
Approche d'un territoire de montagne : occupations humaines et contexte pédo-sédimentaire des versants du col du Petit-Saint-Bernard, de la Préhistoi…
2014
As part of a multi-year programme, survey campaigns have been carried out on both slopes of the Petit-Saint-Bernard pass (2188 m, western Alps), at an altitude of between 750 and 3000 m. The method employed abandons ground-based surveying in favour of multiple manual surveys carried out on selected topographic contexts down to the base of the Holocene fill. The results obtained document the longterm development of the pedo-sedimentary dynamic and the occupation of the different altitude stages. The significance of the archaeological data collected is discussed in relation to the state of knowledge in a comparison area including the neighbouring valleys of the western Alps, to existing settl…
Manipulating Individual Decisions and Environmental Conditions Reveal Individual Quality in Decision-Making and Non-Lethal Costs of Predation Risk
2012
Habitat selection is a crucial decision for any organism. Selecting a high quality site will positively impact survival and reproductive output. Predation risk is an important component of habitat quality that is known to impact reproductive success and individual condition. However, separating the breeding consequences of decision-making of wild animals from individual quality is difficult. Individuals face reproductive decisions that often vary with quality such that low quality individuals invest less. This reduced reproductive performance could appear a cost of increased risk but may simply reflect lower quality. Thus, teasing apart the effects of individual quality and the effect of pr…
Increasing human environmental footprint does not lead to biotic homogenization of forest bird communities in northern USA
2023
Studies have shown negative impacts of increased human pressures on biodiversity at local (alpha-diversity) and regional (gamma-diversity) scales. However, the diversity between local sites (beta-diversity) has received less attention. This is an important shortcoming since beta- diversity acts as a linkage between the local and regional scales. Decreased beta- diversity means that local sites lose their distinctiveness, becoming more similar to each other. This process is known as biotic homogenization. However, the mechanisms causing biotic homogenization have not been fully studied nor its impacts on different facets of biodiversity. We examined if land- use change due to human actions c…
A synthesis of multi-taxa management experiments to guide forest biodiversity conservation in Europe
2023
Most European forests are used for timber production. Given the limited extent of unmanaged (and especially primary) forests, it is essential to include commercial forests in the conservation of forest biodiversity. In order to develop ecologically sustainable forest management practices, it is important to understand the management impacts on forest-dwelling organisms. Experiments allow testing the effects of alternative management strategies, and monitoring of multiple taxa informs us on the response range across forest-dwelling organisms. To provide a representative picture of the currently available information, metadata on 28 multi-taxa forest management experiments were collected from…
Emancipazione pubblica e oppressione privata. Tratteggi di una gender violence tardo moderna nell'incrociarsi di paradigmi atlantici e mediterranei
2016
The paper intends to focus on the unfinished character of a slow-modernity where women are still in the balance between legitimacy frame concerning their emancipation in the public sphere, and representation frame of traditional roles of spouse and mother in private life; between postmodern values, accepted rationally, and premodern values, internalized emotionally. It often happens so that even the most educated women of the middle and upper class accept and legitimize in the private sphere the symbolic and indirect violence, and sometimes the physical violence by their partners in an effort to reconcile public post-modern expectations and private pre-modern expectations. As the «Acrobat o…
Sex-specific genetic differences in endurance swimming of Trinidadian guppies.
2015
Abstract Swim performance is considered a main fitness‐determining trait in many aquatic organisms. Swimming is generally the only way most aquatic prey can escape predation, and swimming capacity is directly linked to food capture, habitat shifts, and reproduction. Therefore, evolutionary studies of swim performance are important to understand adaptation to aquatic environments. Most studies, however, concentrate on the importance of burst‐swim responses to predators, and little is known about its effect on endurance. Even fewer studies associate differences in organism swim capabilities to key gender‐specific responses. In this experiment, we assess the gender‐specific genetic basis of sw…
Genere e servizio sociale. Habitus professionali, dinamiche di relazione, rappresentazioni
2015
Il volume affronta la questione del genere nel servizio sociale, caratterizzandola in un contesto locale-nazionale e, nel contempo, aprendo lo sguardo alla dimensione internazionale. L’analisi della letteratura europea, delle statistiche e della tipizzazione mediale, in una dinamica di rimandi incrociati, si confronta con “caso siciliano”, campo d’analisi della ricerca condotta. Viene quindi evidenziato come la preponderanza numerica delle professioniste donne, in un mestiere considerato tradizionalmente femminile, pone in campo la convergenza di pregiudizi mediterranei e dominio maschile, ma anche di diktat riduzionistici della validità delle performance professionali improntati all'empati…
Exploring land snails’ response to habitat characteristics and their potential as bioindicators of riparian forest quality
2021
Abstract Riparian ecosystems are crucial for landscape-level biodiversity, especially in highly anthropic and agricultural areas. Although the low mobility of snails reduces their dispersal capacity and makes them vulnerable to habitat degradation, they are less commonly used as indicators. We evaluated the potential of land snails as bioindicators of riparian forest quality in central European riparian forests by surveying snail communities in relation to habitat characteristics that characterize its quality. Habitat characteristics were found to affect both snail abundance and species richness. The abundance of snail species increased with the forest continuity, forest width and abundance…
HERPETOFAUNA DI HUTAN DATARAN RENDAH HAYA, MAMBERAMO, PAPUA
2008
<p><em>During about 19 days field work survey (7-25 February 2008) on the Haya lowland forest area, Mamberamo Papua. Eksploration is the methods used in this study. Reptiles and amphibians were collected by hand on the night and day in several type of habitat (plains, swamp, oxbowlake, stream, creeks and hills). The result showed that 48 species of herpetofauna (21 species frogs, 19 species of lizard, six species of snakes and one species of turtles and crocodile) were found.</em></p>
