D.; Zartman, Charles E.; Zuleta, Daniel; Jímenez-Alfaro, Borja (2020)
    Vascular epiphytes are a diverse and conspicuous component of biodiversity in tropical and subtropical forests. Still, the patterns and drivers of epiphyte assemblages are poorly studied in comparison to soil-rooted plants. ...
  • Functional Ecology of Vascular Epiphytes

    Tay, Jessica Y. L.; Zotz, Gerhard; Puczylowski, Jaroslaw; Einzmann, Helena J. R. (2021)
    Vascular epiphytes represent almost 10% of all terrestrial plant diversity. Being structurally dependent on trees, epiphytes live at the interface of vegetation and atmosphere, making them susceptible to atmospheric changes. ...
  • Holding on or falling off: The attachment mechanism of epiphytic <I>Anthurium obtusum</I> changes with substrate roughness 
    Tay, Jessica Y. L.; Kovalev, Alexander; Zotz, Gerhard; Einzmann, Helena J. R.; Gorb, Stanislav N. (2022)
  • Host tree phenology affects vascular epiphytes at the physiological, demographic and community level 
    Einzmann, Helena J. R.; Beyschlag, Joachim; Hofhansl, Florian; Wanek, Wolfgang; Zotz, Gerhard (2015)
    The processes which govern diverse tropical plant communities have rarely been studied in life-forms other than trees. Structurally dependent vascular epiphytes, a major part of tropical biodiversity, grow in a three-dimensional ...
  • How Epiphytic Are Filmy Ferns? A Semi-Quantitative Approach 
    Zotz, Gerhard; Einzmann, Helena J. R. (2023)
    Similar to plants in many other families, members of the Hymenophyllaceae use numerous substrates for growth, e.g., soil, rocks or tree bark. However, substrate preference does not only differ among species but can also ...
  • The Impact of a Severe El Niño Event on Vascular Epiphytes in Lowland Panama 
    Einzmann, Helena J. R.; Weichgrebe, Letizia; Zotz, Gerhard (2022)
    As climate change leads to increasing temperatures, tropical dry seasons are expected to become more severe. An overall intensification of drought events may strongly affect vascular epiphytes. Especially at the community ...
  • Long-term community dynamics in vascular epiphytes on <I>Annona glabra</I> along the shoreline of Barro Colorado Island, Panama 
    Einzmann, Helena J. R.; Weichgrebe, Letizia; Zotz, Gerhard (2021)
    Despite the ecological importance of vascular epiphytes in the tropics, even basic information on the processes that form epiphyte communities is scarce. This is partially due to an almost complete lack of long-term studies. ...
