In Quebec, the fluvial dynamics of the Escoumins River have been disturbed by the forestry industry for over a century. Most specifically, a dam was built near the mouth of the river in 1846 and dismantled in 2013. These disturbances had significant repercussions on the equilibrium of the river and Atlantic salmon habitat. This study therefore proposes to characterize the fluvial dynamics of the Escoumins River and to analyze the impacts of the dam dismantling from the perspective of restoring hydrogeomorphological processes and improving Atlantic salmon habitat. The results suggest that the trajectory of the river evolved differently depending on the fluvial style and the grain size composition of each of its homogeneous segments. However, log drive activities in river and dam removal appear to have been the most important controlling factors on the evolution of the stream trajectory. The dismantling notably allowed the restoration of hydrogeomorphological processes and the free movement of salmonids. A better procedure for dam removal and monitoring should be put in place in Canada to encourage this practice. 相似文献

Slate was a prominent tool material in the Scandinavian Stone Age. However, details of tool function have relied on morphology and have added little to our understanding of their role in hunting and processing. Here, we demonstrate that it is possible to identify both the use-wear traces and residues from slate knives from northern Norway. By applying a multi-disciplinary approach incorporating experimentation, use-wear and organic residue analyses, we identified residues, including seal hair, and use-traces which indicate the tools were used to process fresh marine mammals. 相似文献

AbstractAs a way to commemorate the 25th anniversary of Gender, Place and Culture: A Journal of Feminist geography, the journal sought to highlight the status of feminist geography across the globe. This special issue gives an overview of feminist geography as a praxis and an intellectual field across 39 countries. This process has highlighted the contemporary nature of feminist geographical knowledge construction across multiple scales and diverse contexts. What is evident is that with feminist geography spreading beyond Anglo-American countries, what and who defines the field has drastically changed. We suggest that this means paying much closer attention to the unequal plains of knowledge construction while engaging with transnational dialogue that fosters networks of solidarity. The plurality of feminist geographies that exist today enriches the field in ways that are just becoming apparent, we hope that this special issue will contribute to a fruitful and ongoing discussion towards this aim. 相似文献

After more than a century of research into Bronze Age helmets throughout Europe, both the development and chronology of conical helmets with spool‐shaped sockets still remain unclear. The comprehensive studies and analysis of the helmet from Biecz have not completely resolved the discussions. Other helmets, when not solitary finds, have been usually dated according to their alleged associations in a hoard but have never been extensively discussed as a single helmet type of one date range. By introducing to the discussion a Greek bronze helmet with incised boar's tusks as well as those boar's‐tusk helmets with bronze cheek plates, more light is shed on the development and chronology of these very first European bronze helmets. 相似文献
