We analyze types of projects led by Soviet specialists and engage into the question of how Soviets, both leadership and engineers, viewed their roles and impacts as well as challenges on African territory and Cuba. In so doing, this paper analyzes differences and similarities in Soviet penetration to lands with newly established governments in Africa and Cuba. JEL Classification: N60, N67, N97.

These include complex effects of multiple abiotic and biotic stressors that may drive population losses. These losses are especially illustrated by amphibians, whose populations are declining worldwide. The causes of amphibian population declines are multifaceted and context-dependent. One major factor affecting amphibian populations is emerging infectious disease. Several pathogens and their associated diseases are especially significant contributors to amphibian population declines.

  • Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
    1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus).

With its primary focus on Southeast Asia Region, the Project seeks innovative understandings of the agrarian transition understood as the multiple, uneven, and reversible pathways and processes through which agrarian rela- tions are transformed. Key processes being studied include agricultural intensification and expansion; commodification; peri/urbanization, industrialization, human mobilities, intensification of regulation; ecological change; agrarian social movements; and the re- making of agrarian wealth and poverty. The Project involves an interdisciplinary team from Canada, Southeast Asia, Europe, and Australia. It is directed by Professor Rodolphe De Koninck, Canada Research Chair in Asian Studies, Université de Montreal, Canada. It runs from 2005 to 2010. For more information: http://www.caac.umontreal.ca/en/chatsea_intro.html ChATSEA Working Papers The ChATSEA Working Paper Series is intended to present empirical findings from origi- nal research concerning the agrarian transition, with an emphasis on contemporary con- text. The Series includes work done by faculty and graduate students sponsored by or af- filiated with ChATSEA, and by other scholars who are not affiliated but whose research concerns similar themes.

  • I Politics and Practices of Conservation Governance and Livelihood Change in Two Ethnic Hmong Villages and a Protected Area In
    Politics and practices of conservation governance and livelihood change in two ethnic Hmong villages and a protected area in Yên Bái province, Vietnam. Bernhard Huber Department of Geography McGill University, Montreal A thesis submitted to McGill University in partial fulfillment of the requirements of the degree of Doctor of Philosophy © Bernhard Huber 2019 i Abstract What happens in a remote village of traditional shifting cultivators and hunters when, in the course of twenty years, traditional livelihood practices are banned, alternative income opportunities emerge, a protected area is established, and selected villagers are paid to patrol fellow villagers’ forest use? In this thesis, I aim to investigate how ethnic Hmong villagers in Mù Cang Chải district, Yên Bái Province, Vietnam, and their livelihood practices have intersected with outside interventions for rural development and forest conservation since 1954. Addressing five research questions, I examine historical livelihood changes, contemporary patterns of wealth and poverty, the institutionalisation of forest conservation, the village politics of forest patrolling and hunting, as well as the local outcomes of Vietnam’s nascent Payments for Ecosystem Services (PES) program. I find that these aspects vary significantly within and between two Hmong villages, in which I collected most of my data. The forced transition in the 1990s from shifting cultivation to paddy cultivation increased food security, but has also resulted in new patterns of socio-economic differentiation, as some households had limited access to paddy land. More recently, socio-economic differentiation has further increased, as households have differently benefited from PES, government career opportunities and bank loans. These sources of financial capital are increasingly relevant to peasant livelihoods elsewhere in Vietnam, but remain largely under-studied.

Discovery of Bsal in a captive in salamander die-off events in Europe (Martel et al. 2013) and salamander collection in the United Kingdom, and associated was found to be lethal to multiple Western Palearctic salamander mortality, further raised concerns for trade-mediated disease species in a laboratory challenge experiment (Martel et al.
