    Grooming is a widespread behavior in the animal kingdom primarily geared towards the care of the body surface; nonetheless, other behavioral functions have been investigated and postulated. For example, rodents display ...
  • Variations of Hodge Structures of Rank Three k-Higgs Bundles and Moduli Spaces of Holomorphic Triples 

    Zúñiga Rojas, Ronald Alberto (2020)
    There is an isomorphism between the moduli spaces of σ-stable holomorphic triples and some of the critical submanifolds of the moduli space of k-Higgs bundles of rank three, whose elements (E, ϕk ) correspond to variations ...

    Chytrids are a diverse group of ubiquitous true zoosporic fungi. The recent molecular discovery of a large diversity of undescribed chytrids has raised awareness on their important, but so far understudied ecological role ...
  • Microplastics alter composition of fungal communities in aquatic ecosystems 

    Kettner, Marie Therese; Rojas Jiménez, Keilor Osvaldo; Oberbeckmann, Sonja; Labrenz, Matthias; Grossart, Hans-Peter (2017)
    Despite increasing concerns about microplastic (MP) pollution in aquatic ecosystems, there is insufficient knowledge on how MP affect fungal communities. In this study, we explored the diversity and community composition ...

    Pollution by microplastics in aquatic ecosystems is accumulating at an unprecedented scale, emerging as a new surface for biofilm formation and gene exchange. In this study, we determined the permissiveness of aquatic ...
  • Aquatic fungi: targeting the forgotten in microbial ecology 

    Grossart, Hans-Peter; Rojas Jiménez, Keilor Osvaldo (2016-06)
    Fungi constitute important and conspicuous components of aquatic microbial communities, but their diversity and functional roles remain poorly characterized. New methods and conceptual frameworks are required to accurately ...
