  • The spatial and temporal components of functional connectivity in fragmented landscapes
    AMBIO, 2015
    Co-Authors: Alistair G. Auffret, Jan Plue, Sara A. O. Cousins
    Abstract:

    Connectivity is key for understanding how ecological systems respond to the challenges of land-use change and habitat fragmentation. Structural and functional connectivity are both established concepts in ecology, but the temporal component of connectivity deserves more attention. Whereas functional connectivity is often associated with spatial patterns (spatial functional connectivity), temporal functional connectivity relates to the persistence of Organisms in Time, in the same place. Both temporal and spatial processes determine biodiversity responses to changes in landscape structure, and it is therefore necessary that all aspects of connectivity are considered together. in this perspective, we use a case study to outline why we believe that both the spatial and temporal components of functional connectivity are important for understanding biodiversity patterns in the present-day landscape, and how they can also help us to make better-informed decisions about conserving and restoring landscapes and improving resilience to future change.

  • Magnetite magnetosome biomineralization in Magnetospirillum magneticum strain AMB-1: A Time course study
    Chemical Geology, 2019
    Co-Authors: Lucas Le Nagard, Xiaohui Zhu, Hao Yuan, Karim Benzerara, Dennis Bazylinski, Cecile Fradin, Adrien Besson, Sufal Swaraj, Stefan Stanescu, Rachid Belkhou
    Abstract:

    Magnetotactic bacteria are a highly studied group of diverse prokaryotes that 15 biomineralize chains of magnetosomes, single domain, single crystal magnetic nanoparticles of 16 magnetite or greigite, enclosed by a lipid bilayer membrane whose synthesis is under strict 17 control. in addition to characterizing the genetics and physicochemical properties of both 18 and uncultured environmental species, there have been a number of investigations using a Time 19 course approach to determine the chemical pathway of magnetite biomineralization in these 20 Organisms. in Time course studies, cells of MTB are typically grown in the absence of iron so 21 cannot make magnetite, and then provided with iron in culture medium which initiates the 22 biomineralization of magnetosome chains over a subsequent Time period. Results from previous 23 Time course studies are not consistent with one another, differing with regard to the nature of 24 chemical intermediates and the rate of establishment of magnetosome chains. in this work we 25 report a Time course study of Magnetospirillum magneticum strain AMB-1 over a 48 hour (h) 26 period, using transmission electron microscopy (TEM) and soft X-ray scanning transmission 27 X-ray microscopy (STXM) at the Fe Ledge. STXM provides capability to measure X-ray 28 absorption spectra (XAS) and map chemical species with ~25 nm spatial resolution and thus 29 detailed results on the chemistry of individual particles in single cells.
