  2. 1. Interorganellar connectivity : From protein to lipid homeostasis

    Author : Carlotta Peselj; Sabrina Büttner; Tim Levine; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interorganellar connectivity; nucleus; NVJs; chronic lipid bilayer stress; glucose and phosphate exhaustion; nutritional regimes; transmembrane chaperone; IPTP; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Interorganellar connectivity is fundamental for the maintenance of organellar and cellular functionality and viability. This is achieved and maintained by a complex network of signaling cascades, vesicle trafficking between organelles as well as by establishment of direct physical contact at membrane contact sites (MCS).

  4. 2. Distributed connectivity algorithms

    Author : Esther Jennings; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Abstract : The goal of this research is to design efficient distributed algorithms which execute on an arbitrary network to recognize special connectivity structures within that network. In some cases, we also consider the maintenance of these special structures in dynamically changing networks. READ MORE

  5. 3. Seed mobility and connectivity in changing rural landscapes

    Author : Alistair G. Auffret; Sara Cousins; Robin Pakeman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Conservation; Functional connectivity; Historical ecology; Human-mediated dispersal; Invasive species; Landscape Ecology; Long-distance dispersal; Restoration; Seed bank; Seed dispersal; Seed rain; Structural connectivity; Physical Geography; naturgeografi;

    Abstract : The success or failure of many organisms to respond to the challenges of habitat destruction and a warming climate lies in the ability of plant species to disperse between isolated habitats or to migrate to new ranges. European semi-natural grasslands represent one of the world's most species-rich habitats at small scales, but agricultural intensification during the 20th century has meant that many plant species are left only on small fragments of former habitat.

  6. 4. The architecture of the aging brain : functional reorganization, structural changes, and the role of dopamine receptors

    Author : Robin Pedersen; Alireza Salami; Anna Rieckmann; Anders Wåhlin; Lars Nyberg; Roser Sala-Llonch; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain architecture; functional connectivity; dopamine; aging; cognition; memory; functional magnetic resonance imaging; positron emission tomography; graph theory; Laplacian eigenmapping; gradient;

    Abstract : Aging is associated with reorganization of functional brain architecture, potentially leading tocognitive decline in older age. However, the mechanisms responsible for alterations in functionalbrain architecture remain poorly understood. READ MORE

  7. 5. Hidden biodiversity in an alpine freshwater top predator : Existence, characteristics, and temporal dynamics of cryptic, sympatric brown trout populations

    Author : Anastasia Andersson; Linda Laikre; Nils Ryman; Paulo Prodöhl; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cryptic sympatry; population genetic structure; sympatric populations; intraspecific biodiversity; genetic monitoring; conservation genetics; trophic polymorphism; genetic connectivity; temporal stability; Salmo trutta; populationsgenetik; Population Genetics;

    Abstract : Intraspecific genetic diversity is imperative to the survival of species in a changing environment, and it plays a vital role in ecosystem function. Since this type of diversity can be difficult to detect it is sometimes referred to as “hidden biodiversity”. READ MORE
