  • Diversity is maintained by seasonal variation in species abundance 

    Shimadzu, Hideyasu; Dornelas, Maria; Henderson, Peter A; Magurran, Anne (2013-09-04) - Journal article
    Background Some of the most marked temporal fluctuations in species abundances are linked to seasons. In theory, multi-species assemblages can persist if species use shared resources at different times, thereby minimizing ...
  • Exotic invaders gain foraging benefits by shoaling with native fish 

    Camacho Cervantes, Morelia; Macias Garcia, Constantino De Jesus; Ojanguren, Alfredo Fernandez; Magurran, Anne (2014-11-19) - Journal article
    Freshwater habitats are under increasing threat due to invasions of exotic fish. These invasions typically begin with the introduction of small numbers of individuals unfamiliar with the new habitat. One way in which the ...
  • Fitness consequences of female multiple mating : A direct test of indirect benefits 

    Barbosa, Miguel; Connolly, Sean R; Hisano, Mizue; Dornelas, Maria; Magurran, Anne (2012-09-15) - Journal article
    Background The observation that females mate multiply when males provide nothing but sperm - which sexual selection theory suggests is unlikely to be limiting - continues to puzzle evolutionary biologists. Here we test the ...
  • From species to communities : the signature of recreational use on a tropical river ecosystem 

    Deacon, Amy Elizabeth; Shimadzu, Hideyasu; Dornelas, Maria; Ramnarine, Indar W.; Magurran, Anne (2015-12) - Journal article
    Disturbance can impact natural communities in multiple ways. However, there has been a tendency to focus on single indicators of change when examining the effects of disturbance. This is problematic as classical diversity ...
  • The geometric mean of relative abundance indices : a biodiversity measure with a difference 

    Buckland, Stephen Terrence; Studeny, Angelika Caroline; Magurran, Anne; Illian, Janine Baerbel; Newson, Stuart (2011-09-02) - Journal article
    The 2010 Biodiversity Target of the Convention on Biological Diversity (CBD), set in 2002, which stated that there should be ‘a significant reduction of the current rate of biodiversity loss' by 2010, highlighted the need ...
  • Local and regional rarity in a diverse tropical fish assemblage 

    Hercos, A; Sobansky, M; Queiroz, H; Magurran, Anne (2013-01) - Journal article
    Because most species in an ecological assemblage are rare, much of the species richness we value is due to taxa with few individuals or a restricted distribution. It has been apparent since the time of ecological pioneers ...
  • Measuring temporal turnover in ecological communities 

    Shimadzu, Hideyasu; Dornelas, Maria; Magurran, Anne (2015-12) - Journal article
    1.Range migrations in response to climate change, invasive species and the emergence of novel ecosystems highlight the importance of temporal turnover in community composition as a fundamental part of global change in the ...
  • Quantifying temporal change in biodiversity : challenges and opportunities 

    Dornelas, Maria; Magurran, Anne; Buckland, Stephen Terrence; Chao, Anne; Chazdon, Robin L; Colwell, Robert K; Curtis, Tom; Gaston, Kevin J; Gotelli, Nicolas J; Kosnik, Matthew A; McGill, Brian; McCune, Jenny L; Morlon, Hélène; Mumby, Peter J; Øvreås, Lise; Studeny, Angelika; Vellend, Mark (2013-01-07) - Journal article
    Growing concern about biodiversity loss underscores the need to quantify and understand temporal change. Here, we review the opportunities presented by biodiversity time series, and address three related issues: (i) ...
  • Rapid biotic homogenization of marine fish assemblages 

    Magurran, Anne; Dornelas, Maria; Moyes, Faye Helen; Gotelli, Nicholas J; McGill, Brian (2015-09-24) - Journal article
    The role human activities play in reshaping biodiversity is increasingly apparent in terrestrial ecosystems. However, the responses of entire marine assemblages are not well-understood, in part, because few monitoring ...
  • Reasons for the invasive success of a guppy (Poecilia reticulata) population in Trinidad 

    Sievers, Caya; Willing, Eva-Maria; Hoffmann, Margarete; Dreyer, Christine; Ramnarine, Indar; Magurran, Anne (2012-05-31) - Journal article
    The introduction of non-native species into new habitats poses a major threat to native populations. Of particular interest, though often overlooked, are introductions of populations that are not fully reproductively ...
