Taxonomic Analysis

The literature data on the brioflora in “Cape Martyan” nature reserve have been summarized in the article. The annotated listing of bryophytes in the territory, which includes 71 species: 3 liverworts and 68 mosses, is reproduced. A taxonomic, sozological and geographic analysis of brioflora in the nature reserve is set out in the paper. The briological materials lend credence to a high scientific significancy and conservation value of the nature reserve territory.

AbstractGeographic analysis has long supported transport plans that are appropriate to local contexts. Many incumbent ‘tools of the trade’ are proprietary and were developed to support growth in motor traffic, limiting their utility for transport planners who have been tasked with twenty-first century objectives such as enabling citizen participation, reducing pollution, and increasing levels of physical activity by getting more people walking and cycling. Geographic techniques—such as route analysis, network editing, localised impact assessment and interactive map visualisation—have great potential to support modern transport planning priorities. The aim of this paper is to explore emerging open source tools for geographic analysis in transport planning, with reference to the literature and a review of open source tools that are already being used. A key finding is that a growing number of options exist, challenging the current landscape of proprietary tools. These can be classified as command-line interface, graphical user interface or web-based user interface tools and by the framework in which they were implemented, with numerous tools released as R, Python and JavaScript packages, and QGIS plugins. The review found a diverse and rapidly evolving ‘ecosystem’ tools, with 25 tools that were designed for geographic analysis to support transport planning outlined in terms of their popularity and functionality based on online documentation. They ranged in size from single-purpose tools such as the QGIS plugin AwaP to sophisticated stand-alone multi-modal traffic simulation software such as MATSim, SUMO and Veins. Building on their ability to re-use the most effective components from other open source projects, developers of open source transport planning tools can avoid ‘reinventing the wheel’ and focus on innovation, the ‘gamified’ A/B Street https://github.com/dabreegster/abstreet/#abstreet simulation software, based on OpenStreetMap, a case in point. The paper, the source code of which can be found at https://github.com/robinlovelace/open-gat, concludes that, although many of the tools reviewed are still evolving and further research is needed to understand their relative strengths and barriers to uptake, open source tools for geographic analysis in transport planning already hold great potential to help generate the strategic visions of change and evidence that is needed by transport planners in the twenty-first century.

Since its origins, geography has prioritized the study of nature. However, more recently the discipline has made advancements in studying power as a fundamental element in the social production of space and territory. What can Marxism offer to such investigations? In this brief article, I highlight some of the contributions of Marxist thought that I have found useful for geographic analysis and that stand out from the discipline’s other forms of analysis. Firstly, I recover elements from the thinker Antonio Gramsci that I consider important for debates regarding the social production of space and territory as an expression of power relations. Secondly, I retrace some aspects of Marx's concept of nature to examine certain notions that prevail in today's environmental debates. In this way, I look to denaturalize the hegemonic thought with which institutions and dominant classes exercise power in this area.
