Full textThe moss layer transfer technique, widely used for peatland restoration after peat extraction in North America, aims to facilitate plant cover re-establishment dominated by peat-accumulating mosses. Efficient in that regard, the approach fails to restore habitat heterogeneity that supports the high biodiversity of natural peatlands. Peatland pools are habitats with an associated characteristic fauna and flora, contributing significantly to peatland biodiversity. In restored peatlands, man-made pools should increase habitat heterogeneity and thus, species diversity. In virtually all ecosystems, arthropods are diverse and abundant, and they are sensitive to fine-scale environmental changes, making them relevant as ecological indicators. To assess how pools should be designed in order to facilitate arthropod recolonization, 21 pools distributed in two depth classes (deep and shallow) and three vegetation classes (mosses, shrubs and graminoid plants) were designed in a restored fen in the Bas-Saint-Laurent region. Four natural fens with pools of the same region were assessed as reference ecosystem. Spiders (Araneae) and predacious diving beetles (Coleoptera: Dytiscidae) were sampled around and within pools using pitfall traps and funnel minnow traps, respectively. In order to determine how treatments and measured environmental variables influence arthropod assemblages, the later were compared, using multivariate analysis, between pools in the restored and reference ecosystems. Of the three vegetation types tested, man-made pools with graminoid plants showed an arachnofauna and a microenvironment more similar to the reference ecosystem. Dytiscid diversity of shallow man-made pools was similar to that of reference ecosystem. The creation of pools of variable depth and the introduction of graminoid-type vegetation on pool margins is recommended in restored fens in order to optimize the return of a biodiversity similar to reference ecosystems.

Full textBroad-leaf cattail (Typha latifolia, a native plant in North America) and common reed (Phragmites australis, haplotype M, the exotic Eurasian genotype) are often observed in Sphagnum-dominated peatlands once peat extraction activities have ceased. Both species are tall opportunistic herbs showing highly competitive behavior through vegetative propagation and seed production. They are invasive in peatlands that have been used for peat extraction and could become a major threat to restoration projects by preventing the establishment of desirable plant species and potentially reducing carbon sequestration. Furthermore, seed dispersal could contaminate adjacent commercial peat fields. Dense, nearly monospecific, patches of Cattail and Reed have been recently identified in two bogs located in eastern Canada cutover bogs. The main objective of this project was to evaluate and test methods to prevent the spread of these invasive plants in peatlands. Different control methods, such as repeated stem cutting, tarping and revegetation were tested on cattails and reeds, at Bois-des-Bel (BDB, a restored peatland) and Saint-Alexandre-de-Kamouraska (SAK, an unrestored site). Repeated cuttings (3 times per summer) decreased cattail stem density by 77 % and biomass by 88 % compared to control (no cutting) sites. Field observations suggest that a combination of tarping and planting willows to rapidly establish a dense plant cover could inhibit the regrowth of reeds. This project examines a new aspect of biological invasions in North American peatlands. It contributes to the development of technical and operational expertise regarding invasive plant control, based on experimental evidence.

Full textThe impact of public subsidies is subject for a debate: some thinks that public interventions could stimulate effect on the economy, while for others, the public interventions would be useless and respond more of political interests than economic efficiency. From a regional development and public policy perspective, this paper focus on the impact of public subsidies on the performance of firms in a non-metropolitan area. Performance is measured from two differents but complementary angles: the survival of firms and the average annual growth of employees. This study uses a rich database composed of 15 187 active establishments in the Lower-Saint-Lawrence region in between 2006 and 2015. A spatial matching methodology is applied in this study, based on propensity score matching, calculated on the basis of local indicators (spatial), as in Dubé and Brunelle (2014). The results show a positive effect of the public subsidies on the performance of firms. However, this effect can change depending on the criteria that used to measure performance (survival or employment growth) or the productive sector. Globally, is found that public subsidies have a positive effect on the employment growth of the firms, but this effect is not significant for the survival of firms. Depending on the productive sectors, the effect of public subsidies on employment growth would be principally attributable to the manufacturing sector, and the effect of public subsidies on firm survival would be marked in the primary and upper tertiary sectors.
