TLDR
A conceptual competition model based on plant growth forms common in global forests, i.e. graminoids, forbs, small shrubs, large shrubs and mid- storey trees, and main-storey trees is presented and their competitive attributes and successional dynamics are examined.Abstract:
Summary Plant interactions can be defi ned as the ways plants act upon the growth, fi tness, survival and reproduction of other plants, largely by modifying their environment. These interactions can be positive (facilitation) or negative (competition or exploitation). During plantation establishment or natural forest regeneration after a disturbance, high light levels and, sometimes, increased availability of water and nutrients favour the development of opportunistic, fast-growing herbaceous and woody species which capture resources at the expense of crop trees. As a consequence, the growth and survival of crop trees can be dramatically reduced. Although the effects of this competition are well documented, the physical and physiological mechanisms of competition are not. Moreover, the competition process is never constant in time or space. We present a conceptual competition model based on plant growth forms common in global forests, i.e. graminoids, forbs, small shrubs, large shrubs and mid-storey trees, and main-storey trees. Their competitive attributes and successional dynamics are examined. An overview is presented on the way forest vegetation management (FVM) treatments infl uence these components and outcomes regarding crop tree performance and diversity conservation. Finally, a synthesis of literature yields FVM guidelines for effi ciently optimizing crop tree performance and safeguarding diversity. Future research needs to further sustainable FVM are presented.read more

Influence of tree species on understory vegetation diversity and mechanisms involved—A critical review for temperate and boreal forests
TL;DR: In this article, the authors reviewed and analyzed the literature on the relationship between tree species composition and floristic diversity, including the mechanisms involved therein, and found that mixing of deciduous and coniferous tree species generally affects understory diversity, but in almost all cases maximum diversity is observed in one of the pure stands, not in mixed stands.

TL;DR: It is argued that a simultaneous investigation of both overstorey and understorey functional responses to global change will be crucial and that such studies are still very scarce, only available for a limited set of ecosystem functions and limited to quantification, providing little data to forecast functional responsesto global change.

Influence of several tree traits on rainfall partitioning in temperate and boreal forests: a review
TL;DR: In this paper, the authors compared water flows among tree species in temperate and boreal forests to test the effect of several tree traits on water flows, and found that water flows differed between evergreen and deciduous species according to successional status and bark roughness.

Predicting conifer establishment post wildfire in mixed conifer forests of the North American Mediterranean‐climate zone
TL;DR: In this article, the authors measured site characteristics, seedling densities, woody shrub, and tree growth to understand the importance of each measured variable in predicting conifer regeneration.

Plant Strategies and Vegetation Processes
TL;DR: In this paper, the authors present plant strategies in the established phase and the regenerative phase in the emerging phase, respectively, and discuss the relationship between the two phases: primary strategies and secondary strategies.

Mechanisms of succession in natural communities and their role in community stability and organization
TL;DR: In the majority of natural communities succession is frequently interrupted by major disturbances, such as fires, storms, insect plagues, etc., starting the process all over again, but if not interrupted, it eventually reaches a stage in which further change is on a small scale as individuals die and are replaced.

Ecology: Individuals Populations and Communities
TL;DR: A revised and updated edition of this textbook is presented in this paper, with a clear presentation of mathematical aspects and the material aims to be accessible to the undergraduate with little experience and also stimulating to practising ecologists.
Book
Plant Physiological Ecology
TL;DR: This textbook is notable in emphasizing that the mechanisms underlying plant physiological ecology can be found at the levels of biochemistry, biophysics, molecular biology and whole-plant physiology, well-suited to assess the costs, benefits and consequences of modifying plants for human needs, and to evaluate the role of plants in ecosystems.

TL;DR: A framework using concepts and results from community ecology, ecosystem ecology and evolutionary biology to provide a linkage between traits associated with the response of plants to environmental factors and traits that determine effects of plants on ecosystem functions is presented.
