      Thiemer, Kirstine; Lennox, Robert; Torske, Astrid; Schneider, Susanne C; Haugen, Thrond O (Peer reviewed; Journal article, 2024)
      Mass development of macrophytes is an increasing problem worldwide and they are frequently removed where they are in conflict with local waterway users. Yet, macrophytes can provide important refuge and nursery habitats ...
    • Behavioural response of brown trout (Salmo trutta) to total dissolved gas supersaturation in a regulated river 

      Lennox, Robert J.; Thiemer, Kirstine; Vollset, Knut Wiik; Pulg, Ulrich; Stranzl, Sebastian; Nilsen, Cecilie Iden; Haugen, Thrond Oddvar; Velle, Gaute (Peer reviewed; Journal article, 2021)
      Total dissolved gas supersaturation from dams and power stations is a chronic freshwater pollutant that is toxic to animals with aquatic respiration. Laboratory ecotoxicology experiments have revealed capacity for captive ...
    • Causes of macrophyte mass development and management recommendations 

      Schneider, Susanne C; Coetzee, Julie A.; Galvanese, Elena Fukasawa; Harpenslager, Sarah Faye; Hilt, Sabine; Immerzeel, Bart; Köhler, Jan; Misteli, Benjamin; Motitsoe, Samuel N.; Padial, Andre A.; Petruzzella, Antonella; Schechner, Anne; Thiébaut, Gabrielle; Thiemer, Kirstine; Vermaat, Jan (Peer reviewed; Journal article, 2024)
      Aquatic plants (macrophytes) are important for ecosystem structure and function. Macrophyte mass developments are, however, often perceived as a nuisance and are commonly managed by mechanical removal. This is costly and ...
    • Does Perceived Nuisance Abundance of Water Plants Match with Willingness-to-Pay for Removal? Contrasts Among Different User Categories 

      Vermaat, Jan; Thiemer, Kirstine; Immerzeel, Bart; Schneider, Susanne Claudia; Sebola, Keneilwe; Coetzee, Julie; Petruzzella, Antonella; Motitsoe, Samuel N.; Baldo, Mathieu; Misteli, Benjamin; Thiébaut, Gabrielle; Hilt, Sabine; Köhler, Jan; Harpenslager, Sarah Faye (Peer reviewed; Journal article, 2024)
      Dense beds of water plants can be perceived as nuisance, but this perception, however, may not be similar for different user categories, and this may affect their willingness-to-pay (WTP) for plant removal. A questionnaire ...
    • Drivers of Perceived Nuisance Growth by Aquatic Plants 

      Thiemer, Kirstine; Immerzeel, Bart; Schneider, Susanne Claudia; Sebola, Keneilwe; Coetzee, Julie; Baldo, Mathieu; Thiébaut, Gabrielle; Hilt, Sabine; Köhler, Jan; Harpenslager, Sarah Faye; Vermaat, Jan (Peer reviewed; Journal article, 2023)
    • The impact of macrophyte removal on macroinvertebrates in the river Otra, Norway 

      Aasland, Eirin (Master thesis, 2021)
      Aquatic macrophytes provide complex ecosystems in the freshwaters around the world. Sometimes, macrophytes can grow to very high biomasses and restrict recreational activities in which it starts being perceived as nuisance ...
    • Influence of dense macrophyte vegetation and total gas saturation on the performance of acoustic telemetry 

      Thiemer, Kirstine; Lennox, Robert; Haugen, Thrond Oddvar (Peer reviewed; Journal article, 2022)
      Acoustic telemetry is widely used as a method for high resolution monitoring of aquatic animal movement to investigate relationships between individual animals and their environment. In shallow freshwater ecosystem, aquatic ...
    • Light and temperature controls of aquatic plant photosynthesis downstream of a hydropower plant and the effect of plant removal 

      Demars, Benoît Olivier Laurent; Schneider, Susanne Claudia; Thiemer, Kirstine; Dörsch, Peter; Pulg, Ulrich; Stranzl, Sebastian Franz; Velle, Gaute; Pathak, Devanshi (Peer reviewed; Journal article, 2023)
    • Mass development of aquatic plants: Effects of contrasting management scenarios on a suite of ecosystem services 

      Vermaat, Jan E.; Thiemer, Kirstine; Immerzeel, Bart; Schneider, Susanne Claudia; Sebola, Keneilwe; Coetzee, Julie; Petruzella, Antonella; Motitsoe, Samuel N.; Baldo, Mathieu; Misteli, Benjamin; Thiébaut, Gabrielle; Hilt, Sabine; Köhler, Jan; Harpenslager, Sarah F. (Peer reviewed; Journal article, 2023)
      1. Dense beds of aquatic plants are often perceived as nuisance and therefore mechanically removed, often at substantial cost. Such removal, however, may affect a range of ecosystem functions and consequently also the ...
    • Mechanical removal of macrophytes in freshwater ecosystems: Implications for ecosystem structure and function 

      Thiemer, Kirstine; Schneider, Susanne C; Demars, Benoît O L (Peer reviewed; Journal article, 2021)
      Macrophytes are generally considered a nuisance when they interfere with human activities. To combat perceived nuisance, macrophytes are removed, and considerable resources are spent every year worldwide on this practice. ...
    • Short-term effects of macrophyte removal on aquatic biodiversity in rivers and lakes 

      Misteli, Benjamin; Pannard, Alexandrine; Aasland, Eirin; Harpenslager, Sarah Faye; Motitsoe, Samuel; Thiemer, Kirstine; Llopis, Stéphanie; Coetzee, Julie; Hilt, Sabine; Köhler, Jan; Schneider, Susanne Claudia; Piscart, Christophe; Thiébaut, Gabrielle (Peer reviewed; Journal article, 2022)
      Mass development of macrophytes is an increasing problem in many aquatic systems worldwide. Dense mats of macrophytes can negatively affect activities like boating, fishing or hydropower production and one of the management ...
