Plant functional traits measured at the individual level within four temperate wetland types (bog, fen, meadow, marsh) in North-East America.
Borealis
Maire, Vincent; Deschamps, Lucas; Proulx, Raphaël — 2023-03-15 We replicated a natural species richness gradient where communities included from 2 to 16 species within four wetlands (bog, fen, meadow, marsh) contrasting in plant productivity. We sampled functional traits from individuals in each community and used hierarchical distributional modelling in order to analyze the independent variation of the mean and dispersion of functional trait space at ecosystem, community and species levels.

Data used to support a meta-analysis investigating ecological effects of urban lawn management
Borealis
Watson, Christopher; Carignan-Guillemette, Léonie; Turcotte, Caroline; Maire, Vincent; Proulx, Raphaël — 2019-11-20 This data supports a meta-analysis investigating ecological impacts of intense lawn management (mowing). Raw data on invertebrate abundance and temperature data was collected by Léonie Carignan-Guillemette (2018) and Caroline Turcotte (2017) under the supervision of Raphaël Proulx and Vincent Maire (refer to Appendix S1 within related publication for more information). Other data was gathered and processed according to the following: We searched the Scopus database on 8 February, 2019 with the following combinations of keywords: (lawn OR turf) AND mowing AND (urban OR city). Generally, studies were ineligible when: full-text of the article was not available even after contacting the authors; mowing was incidental to the study and not an experimental factor; response variables were not ecologically relevant; confounding factors (e.g. fertilisation) could not be isolated; a non-urban context was used; or simulated data were presented. We extracted the mean and statistical variation (standard deviation or standard error) for each response variable in control (less-intensively mown) and treatment (intensively mown) groups. Reported data were used when available. Otherwise, data were extracted from published figures using the Web Plot Digitizer tool. Where summary data on median, and interquartile range was presented, mean and standard deviation was estimated. Variables with multi-temporal data (e.g. soil moisture) were summarised using the mean and pooled standard deviation to provide an aggregated value per site per year. Where seasonal trends were evident in raw multi-temporal data (e.g. soil temperature), data was detrended using a polynomial function and analysis applied to the residuals.

Data from: Field evidence for a rapid adaptive plastic response in morphology and growth of littoral and pelagic brook charr: a reciprocal transplant experiment
Dryad
Pépino, Marc; Magnan, Pierre; Proulx, Raphaël — 2018-05-30 1. Phenotypic plasticity, a process by which individuals modify their morphology, physiology, or behaviour in response to environmental changes, can be seen as the first step in adaptive evolution. Phenotypic plasticity is adaptive if two conditions are met: (i) the phenotype is associated with an environment (plastic response) and (ii) the phenotype–environment association increases individual fitness (adaptive response). 2. Using a reciprocal transplant experiment, we tested the hypothesis that functional morphological responses are correlated with growth at two organizational levels (between and within ecotypes) in brook charr. 3. Four-month-old individuals from four littoral and four pelagic families raised in the laboratory were transferred into eight littoral (3 m × 4 m × 1.5 m depth) and eight pelagic (3 m × 4 m × 6 m depth) lake enclosures for a period of 12 weeks. 4. Fin length (the main discriminant trait of the littoral and pelagic ecotypes) was less plastic than body shape. Growth was higher in the pelagic than in the littoral habitat, but offspring from littoral and pelagic parental origins did not experience higher growth in their respective habitats (comparison between ecotypes). The body shape of most individuals transplanted to their reciprocal environment shifted toward the form expected in that environment. This plastic response in body shape was functionally correlated with growth within ecotypes, but only in the littoral habitat. Furthermore, the within-ecotype variance of both morphological traits and growth were higher in the littoral than in the pelagic habitat. 5. Small phenotypic differences could have direct consequences on fitness in the less favourable habitat, inducing higher inter-individual variance in growth and stronger phenotype–growth associations. We suggest that phenotypic accommodation and cryptic genetic variation, two mechanisms previously proposed as mechanisms involved in distinct situations, could be simultaneously involved to hasten the process of adaptive evolution in an unfavourable environment.
