Islands and introduced herbivores: conservation action as ecosystem experimentation (2002, background): “This lack of large-scale terrestrial experiments is partly due to intrinsic logistical and moral challenges coupled with the recent dominating influence by experimentalists on the methodological philosophy of ecology (Estes 1995; Oksanen 2001).”
Ecological Models and Data in R (2008, background): “The basics of experimental design — the meaning of and need for randomization, control, independence, and replication in setting up experiments, the idea of statistical power, and the concept of pseudoreplication (Hurlbert, 1984; Hargrove and Pickering, 1992; Heffner et al., 1996; Oksanen, 2001) — a”
Burial of seeds and seedlings by the lugworm Arenicola marina hampers eelgrass (Zostera marina) recovery (2011, background): “It must be noted, however, that since only one flume was available for experiments with burial of seed mimics and seedlings, it follows that the retrieved samples and results should be considered ‘pseudoreplicates’ (Oksanen, 2001).”
Invasive Plant and Experimental Venue Affect Tadpole Performance (2006, unknown): “Investigations of invasive plant impacts need to carefully consider appropriate venues (Oksanen 2001; Petersen and Hastings 2001; Skelly and Kiesecker 2001; Skelly 2002).”
Movements of cactus bugs: Patch transfers, matrix resistance, and edge permeability (2004, methodology): “We maintained an appropriate spatial extent for investigating interpatch movements instead of using a smaller scale that would allow for plot replication Hargrove and Pickering 1992; Oksanen 2001 .”
Effects of scale on interpreting life‐history characteristics of ungulates and carnivores (2006, background): “Indeed, sampling at appropriate temporal and spatial scales may be more important than replication for tests of some hypotheses (Oksanen, 2001).”
Effects of grazing by horses and/or cattle on the diversity of coastal grasslands in western France (2004, methodology): “Grazing impacts on botanical composition and diversity occur mainly at small spatial scales and the quadrats sampled in each community and patch type within an enclosure were used as replicates for botanical and diversity analyses of the grazing treatment effect ( Oksanen, 2001 ).”
Genetic differentiation and plasticity interact along temperature and precipitation gradients to determine plant performance under climate change (2017, background): “The conclusions of Hurlbert (1984) on pseudoreplication in growth chamber experiments have, however, been extensively criticized (e.g. Oksanen 2001; Johnson et al. 2016).”
Evaluation of Initial Restoration Measures during the Restoration of Calcareous Grasslands on Former Arable Fields (2006, result): “…of pseudoreplication (Hurlbert 1984) in our study which means that the results of our statistical analysis have to be interpreted with care because we can test—in a strict sense—only for differences between sites and not for differences between experimental treatments (see also Oksanen 2001).”
