Typological and species diversity of dark conifer forests in the lower reaches of the Bol’shaya Porozhnyaya River, a tributary of the Pechora (Pechora-Ilych state nature reserve)

The structure of dark conifer forests in the lower reaches of the Bol’shaya Porozhnyaya River is described. Ordination of corresponding communities has been performed, and their ecological and ecocenotic characteristics and species structure have been analyzed. On this basis, a typological scheme of the forests has been constructed following the method by L.B. Zaugol’nova. The identified sections and variants of communities within the true moss and tall herb sections are described. Successive change of leading ecological factors in the hierarchical series of communities, from sections to variants, is demonstrated.

Sustainability education and a new master’s degree, the master of sustainability science: the Graduate Program in Sustainability Science (GPSS) at the University of Tokyo

The University of Tokyo started its Graduate Program in Sustainability Science (GPSS), offering a master of sustainability science degree, in 2007. The GPSS curriculum consists of: (1) knowledge and concept oriented courses, which cover sustainability-related subjects from a holistic viewpoint; (2) experiential learning and skills oriented practical courses, which offer practical exercises to acquire the skills and sensibility required of future leaders; and (3) the Master’s thesis, for which students are encouraged to address complex sustainability problems through a transdisciplinary approach. Sustainability science is not a discipline that can be defined simply by the subjects it deals with, but is an academic field characterized by core principles that include holistic thinking, transdisciplinarity, and respect for diversity. The GPSS has been designed so that students may gain the capacity to understand and practice these principles. The present paper describes how the GPSS has defined sustainability education and designed its curriculum accordingly.     

A situational analysis of Cameroon’s Technical Operation Units (TOUs) in the context of the landscape approach: critical issues and perspectives

The integrated landscape approach is re-emerging in the global agenda as an approach which can give a fair deal to landscape functions such as climate change response, biodiversity conservation, food security, poverty reduction and economic growth. However, transformational change might be required to enable landscapes respond to these different functions. This is due to the sensitive nature of landscapes to local, national and global economic, social and political drivers. Based on national policy instruments, this paper presents a situational analysis of the landscape concept in Cameroon, operationalized as Technical Operation Units (TOUs) and in the context of the present institutional, social, economic and political features, it examines the rationale for a landscape approach in Cameroon. We notice potential trade-offs, indicating that the landscape approach is an opportunity for TOUs in Cameroon. Firstly, TOUs are characterized by multiple resource regimes with overlapping claims each having a legal land allocation and management plan. Secondly, TOUs are characterized by different stakeholders, with different land-use interests and motives, each controlling key components in the landscapes. Thirdly, the interests and motives of stakeholders overlap spatially and are connected to different sectoral policies at the national level. This setting might threaten decision making and the sustainability potentials of landscapes. Nonetheless, we propose areas for in-depth studies to generate knowledge and information to orientate win–win policy construction for landscapes. This is relevant for the social, ecological and economic objectives that underpin the sustainable development goals proposed in the post-2015 development agenda.     

Chernov’s compensation principle and the effect of rodent community completeness on the variability of bank vole (<Emphasis Type="Italic">Clethrionomys glareolus</Emphasis>) population in the Middle Urals

Using methods of geometric morphometrics, significant differences have been revealed in manifestations of variability and morphological disparity in allochronous samples from the population of model species, the bank vole (Clethrionomys glareolus Schreb. 1780), in the Middle Urals at different levels of rodent community (taxocene) completeness in different years. Two states of the taxocene—oligospecific (two species) and polyspecific (five species)—and the level of relative abundance of bank voles (high or low) have been taken into account. Comparative analysis of variation in the size and shape of the mandible in same-aged (late-summer) young of the year has shown that significant morphogenetic differences exist between the animals sampled from the rodent taxocene at its different states (oligospecific and polyspecific) and, to a lesser extent, at high and low levels of abundance. The level of variation and the parameter of intragroup morphological disparity (MNND) in the mandible shape reach a maximum when the community has a reduced composition and decrease to a minimum when its composition is complete (i.e., in the oligo- and polyspecific taxocene). A parallelism is observed in the manifestation of morphofunctional changes of the mandible in male and female voles under conditions when the taxocene has high abundance and oligospecific composition or low abundance but polyspecific composition. Different morphogenetic responses of the population to oligo- and polyspecific composition of the community are considered as a compensatory increase of morphological disparity in the dominant species (the bank vole) under conditions of incomplete composition of the taxocene and low population density, in accordance with Chernov’s ecological compensation principle.
