    Disease ecology. Ecological and evolutionary effects of fragmentation on infectious disease dynamics (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-06-14
    Description: Ecological theory predicts that disease incidence increases with increasing density of host networks, yet evolutionary theory suggests that host resistance increases accordingly. To test the combined effects of ecological and evolutionary forces on host-pathogen systems, we analyzed the spatiotemporal dynamics of a plant (Plantago lanceolata)-fungal pathogen (Podosphaera plantaginis)relationship for 12 years in over 4000 host populations. Disease prevalence at the metapopulation level was low, with high annual pathogen extinction rates balanced by frequent (re-)colonizations. Highly connected host populations experienced less pathogen colonization and higher pathogen extinction rates than expected; a laboratory assay confirmed that this phenomenon was caused by higher levels of disease resistance in highly connected host populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jousimo, Jussi -- Tack, Ayco J M -- Ovaskainen, Otso -- Mononen, Tommi -- Susi, Hanna -- Tollenaere, Charlotte -- Laine, Anna-Liisa -- New York, N.Y. -- Science. 2014 Jun 13;344(6189):1289-93. doi: 10.1126/science.1253621.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Metapopulation Research Group, Department of Biosciences, University of Helsinki, Post Office Box 65 (Viikinkaari 1), FI-00014 University of Helsinki, Helsinki, Finland. ; Metapopulation Research Group, Department of Biosciences, University of Helsinki, Post Office Box 65 (Viikinkaari 1), FI-00014 University of Helsinki, Helsinki, Finland.

    Metal Sourcing For a Sustainable Future (2022)
    In:  Earth science, systems and society (ES3)
    Details
    Publication Date: 2023-07-18
    Description: Drastic measures are required to meet the standards of the Paris Agreement and limit the increase of global average temperatures well below 2°C compared to pre-industrial levels. Mining activities are typically considered as unsustainable but, at the same time, metals such as cobalt and lithium are essential to sustain the energy transition. Several sustainability goals defined by the United Nations (UN) require large quantities of raw materials. Exploration and extractives activities are required in order to contribute to meeting sustainability standards. Future sourcing of metals will need to implement procedures that go well beyond current ecological, economic, and social requirements and practices. In this paper we assess the usual sustainability criteria and how they apply to the extractives sector. Sustainability can only be achieved if one accepts that the natural capital can be substituted by other forms of capital (so called weak concept of sustainability). Sourcing the raw materials increasingly demanded by our societies will need transparent and inclusive stakeholder participation as well as a holistic understanding of the impact of extractives activities to reach this weak sustainability status. Our analysis shows that the sustainability of mining cannot be reached without harmonized political instruments and investment policies that take the three pillars of environmental, economic, and social sustainability as a major priority.
