    Two decades of non-invasive genetic monitoring of the grey wolves recolonizing the Alps support very limited dog introgression.

    Potential hybridization between wolves and dogs has fueled the sensitive conservation and political debate underlying the recovery of the grey wolf throughout Europe. Here we provide the first genetic analysis of wolf-dog admixture in an area entirely recolonized, the northwestern Alps. As part of a long-term monitoring program, we performed genetic screening of thousands of non-invasive samples collected in Switzerland and adjacent territories since the return of the wolf in the mid-1990s. We identified a total of 115 individuals, only 2 of them showing significant signs of admixture stemming from past interbreeding with dogs, followed by backcrossing. This low rate of introgression (<2% accounting for all wolves ever detected over 1998-2017) parallels those from other European populations, especially in Western Europe (<7%). Despite potential hybridization with stray dogs, few founders and strong anthropogenic pressures, the genetic integrity of the Alpine population has remained intact throughout the entire recolonization process. In a context of widespread misinformation, this finding should reduce conflicts among the different actors involved and facilitate wolf conservation. Real-time genetic monitoring will be necessary to identify potential hybrids and support an effective management of this emblematic population

    The amphibians and reptiles of Mindanao Island, southern Philippines, II: the herpetofauna of northeast Mindanao and adjacent islands

    We summarize all available amphibian and reptile species distribution data from the northeast Mindanao faunal region, including small islands associated with this subcenter of endemic vertebrate biodiversity. Together with all publicly available historical information from biodiversity repositories, we present new data from several major herpetological surveys, including recently conducted inventories on four major mountains of northeast Mindanao, and adjacent islands of Camiguin Sur, Dinagat, and Siargao. We present species accounts for all taxa, comment on unresolved taxonomic problems, and provide revisions to outdated IUCN conservation status assessments in cases where our new data significantly alter earlier classification status summaries. Together, our comprehensive analysis of this fauna suggests that the greater Mindanao faunal region possesses distinct subcenters of amphibian and reptile species diversity, and that until this area is revisited and its fauna and actually studied, with on-the-ground field work including targeted surveys of species distributions coupled to the study their natural history, our understanding of the diversity and conservation status of southern Philippine herpetological fauna will remain incomplete. Nevertheless, the northeast Mindanao geographical area (Caraga Region) appears to have the highest herpetological species diversity (at least 126 species) of any comparably-sized Philippine faunal subregion

    Tangible Lives: Pina/oy Migrant Cultures and Labor in Interwar California, 1920-1941

    No full text
    This dissertation is concerned with the multiple valences of Pina/oy cultural meaning-making from 1920 to 1941. It focuses on alternative practices of labor and leisure in California, where multiple Pina/oy ethnic enclaves throughout the state underscored the critical role that travel, mobility, and inter-dependent community infrastructures played in sustaining the transpacific lifeways of the Filipina/o diaspora during the interwar period. It will examine Pina/oys’ historical negotiations over space, power, and autonomy that occurred on the terrain of several Pina/oy popular cultures. These cultural spaces created the context for alternative modes of work, survival, community-making, and freedom to emerge under U.S. racial regimes

    Scrapping Into A Knot: Pinoy Boxers, Transpacific Fans, And The Troubling of Interwar California's Racial Regimes

    No full text
    This article explores how Filipino boxers and fans in California in the 1920s and 1930s mobilized radical imaginations to creatively express a politics of dissent and liberation from oppressive racial regimes. U.S. imperialism in the Philippines reoriented the shape and direction of Filipino (anti)conquest and resistance following Spanish colonization. As the sport of boxing developed into an influential transpacific cultural industry, Filipino migrant fans inspired pugilists’ performative politics. As they worked and performed in interconnected urban and rural spaces across California, Filipino boxers and their fans destabilized racial scripts while negotiating claims to power, space, and dignity during this period

    Synthesis of a novel lipophilic gadolinium complex as a potential MRI contrast agent

    The synthesis of a novel lipophilic diethylentriaminotetracetic( DTTA)-dodecane gadolinium complex is reported. The Gd-DTTA-dodecane complex is able to form mixed micelles with 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) and a nonionic surfactant like Tween 80. This novel multicomponent system can find potential application in magnetic resonance angiography (MRA)
