Niche partitioning between sympatric wild canids: the case of the golden jackal (Canis aureus) and the red fox (Vulpes vulpes) in north-eastern Italy
No full textAbstract Background Two coexisting species with similar ecological requirements avoid or reduce competition by changing the extent of their use of a given resource. Numerous coexistence mechanisms have been proposed, but species interactions can also be aggressive; thus, generally a subordinate species modifies its realized niche to limit the probability of direct encounters with the dominant species. We studied niche partitioning between two sympatric wild canids in north-eastern Italy: the golden jackal and the red fox, which, based on competition theories, have a high potential for competition. We considered four main niche dimensions: space, habitat, time, and diet. Results We investigated three study areas monitoring target species populations from March 2017 to November 2018 using non-invasive monitoring techniques. Red fox presence was ascertained in every study area, while golden jackal presence was not ascertained in one study area, where we collected data regarding wolf presence. Considering the two target species, we observed partial diet partitioning based on prey size, with the golden jackal mainly feeding on wild ungulates and the red fox mainly feeding on small mammals. The two canids had an extensive temporal overlap along the diel cycle, having both predominant crepuscular and nocturnal activity patterns, but marked spatial partitioning and differential use of habitats. The golden jackal proved to be specialist concerning the habitat dimension, while the red fox resulted completely generalist: the former selected less human-modified habitats and avoided intensively cultivated lands, while the latter was present in all habitats, including intensively cultivated lands. Conclusions The observed partitioning might be due partially to some ecological adaptations (e.g. specialist vs. generalist use of resources) and specific behaviours (e.g. cooperative vs. solitary hunting) and partially to the avoidance response of the red fox aimed at reducing the probability of direct encounters with the golden jackal

Rand, Erica - 2022 Follow Up
No full textErica Rand is a professor of Arts and Visual Culture at Bates College, an adult figure skater, author and activist. This is a follow-up interview to her previous interview for Querying the Past in 2017. Erica Rand was heavily involved with ACT- UP Portland and more specifically the branch of ACT UP called: Pissed Off Dyke Cell and Women’s Health Action Crew. But more recently she has been involved with a new form of activism through sports and writing. At Bates, she is pushing the importance of trans-inclusion policies in sports and even testing the gender limitations put in place in figure skating.https://digitalcommons.usm.maine.edu/querying_ohproject/1095/thumbnail.jp

Products of their Past? Cleavages and Intra-Party Dissent Over European Integration. IHS Political Science Series Paper No. 118. February 2009
No full textWhat explains contemporary intra-party dissent on EU issues? This article develops a cleavage theory model of internal party dissent over European integration. Drawing on Lipset and Rokkan’s classic model of political cleavages and on its applications to party positioning on European integration, I argue that if one seeks to understand when, where, and to what extent internal divisions manifest themselves, one must look to the particular historical vulnerabilities of political parties. Using expert survey data, I demonstrate that the ease with which political parties are able to assimilate the issue of European integration is influenced by the legacy of past political tensions and the extent to which the economic and political aspects of the EU reactivate pre-existing cleavages
