Biotic and abiotic drivers of intraspecific trait variation within plant populations of three herbaceous plant species along a latitudinal gradient
Helsen, Kenny; Acharya, Kamal Prasad; Brunet, J; Cousins, Sara A. O.; Decocq, Guillaume; Hermy, Martin; Kolb, Annette; Lemke, Isgard H.; Lenoir, Jonathan; Plue, Jan; Verheyen, Kris; De Frenne, Pieter; Graae, Bente Jessen (Journal article; Peer reviewed, 2017)Background: The importance of intraspecific trait variation (ITV) is increasingly acknowledged among plant ecologists. However, our understanding of what drives ITV between individual plants (ITVBI) at the population level ... -
Earlier onset of flowering and increased reproductive allocation of an annual invasive plant in the north of its novel range
Helsen, Kenny; Acharya, Kamal Prasad; Graae, Bente Jessen; De Kort, Hanne; Brunet, Jörg; Chabrerie, Olivier; Cousins, Sara A.O.; De Frenne, Pieter; Hermy, Martin; Verheyen, Kris; Pelabon, Christophe (Journal article; Peer reviewed, 2020) -
Invasive Species: Genetics, Characteristics and Trait Variation Along a Latitudinal Gradient
Acharya, Kamal Prasad (Doktoravhandlinger ved NTNU, 1503-8181; 2014:276, Doctoral thesis, 2014)Globalization during the second half of the 20th century has accelerated the introduction and the spread of non-native species. Introduced species is considered the second largest threat to biodiversity after habitat ... -
Low genetic diversity despite multiple introductions of the invasive plant species Impatiens glandulifera in Europe
Hagenblad, Jenny; Hülskötter, Jennifer; Acharya, Kamal Prasad; Brunet, Jörg; Chabrerie, Olivier; Cousins, Sara A.O.; Dar, Pervaiz A; Diekmann, Martin; De Frenne, Pieter; Hermy, Martin; Jamoneau, Aurelien; Kolb, Anette; Lemke, Isgard; Plue, Jan; Reshi, Zafar A; Graae, Bente Jessen (Journal article; Peer reviewed, 2015)Background Invasive species can be a major threat to native biodiversity and the number of invasive plant species is increasing across the globe. Population genetic studies of invasive species can provide key insights ... -
No genetic erosion after five generations for Impatiens glandulifera populations across the invaded range in Europe
Helsen, Kenny; Hagenblad, Jenny; Acharya, Kamal Prasad; Brunet, Jörg; Cousins, Sara A. O.; Decocq, Guillaume; De Frenne, Pieter; Kimberley, Adam; Kolb, Anette; Michaelis, Jana; Plue, Jan; Verheyen, Kris; Speed, James D M; Graae, Bente Jessen (Journal article; Peer reviewed, 2019)Background The observation that many alien species become invasive despite low genetic diversity has long been considered the ‘genetic paradox’ in invasion biology. This paradox is often resolved through the temporal ... -
Pre-adaptation or genetic shift after introduction in the invasive species Impatiens glandulifera?
Elst, Evelyne M.; Acharya, Kamal Prasad; Dar, Pervaiz A.; Reshi, Zafar A.; Tufto, Jarle; Nijs, Ivan; Graae, Bente Jessen (Journal article, 2016)Invasive exotic plants often grow fast, reproduce rapidly and display considerable phenotypic plasticity in their invasive range, which may be essential characteristics for successful invasion. However, it remains unclear ...
