Intraspecific genotypic diversity in plants
Genome, 2011Variations in the nuclear DNA, mainly as a result of quantitative modulations of DNA repeats belonging to different sequence families of satellite DNA and to the activity of transposable elements, have been assessed within several angiosperm species. These variations alter the amount and organization of the DNA and therefore the genotype, rather than ...

Ethnomedicinal plant diversity in Thailand
Journal of Ethnopharmacology, 2018Plants have provided medicine to humans for thousands of years, and in most parts of the world people still use traditional plant-derived medicine. Knowledge related to traditional use provides an important alternative to unavailable or expensive western medicine in many rural communities.

Abstract. Neighbour diversity is the diversity of other plant species contacting a reference species. The expected value and confidence intervals of neighbour diversity assuming random contacts can be found using bootstrapping. In general, frequent species have higher expected neighbour diversities with narrow confidence intervals than infrequent ...

Diversity of plant evolutionary lineages promotes arthropod diversity
Ecology Letters, 2012AbstractLarge‐scale habitat destruction and climate change result in the non‐random loss of evolutionary lineages, reducing the amount of evolutionary history represented in ecological communities. Yet, we have limited understanding of the consequences of evolutionary history on the structure of food webs and the services provided by biological ...

Plant-Microbe Interactions: Chemical Diversity in Plant Defense
Science, 2009The chemical diversity within the plant kingdom is likely to be a consequence of niche colonization and adaptive evolution. Plant-derived natural products have important functions in defense. They also have broader ecological roles and may in addition participate in plant growth and development.

The term ‘lower plants’ is a convenient but imprecise label for a disparate group of plants and plant-like organisms which are defined primarily by their lack of vascular tissue (the transport system for water and nutrients within higher plants). Under this heading we here discuss bryophytes, lichens and larger algae.

When Can Plant-Pollinator Interactions Promote Plant Diversity?
The American Naturalist, 2013In the light of rapid losses of biodiversity worldwide, it has become more important than ever to study the factors that ensure the continued existence of diverse ecological communities. Whereas the diversity-enhancing effects of antagonistic interactions are relatively well understood, much less is known about the contribution of mutualistic ...

Soil biota and plant diversity
Science, 2017Plant Ecology Soil biota, including symbionts such as mycorrhizal fungi and nitrogen-fixing bacteria, as well as fungal and bacterial pathogens, affect terrestrial plant diversity and growth patterns (see the Perspective by van der Putten). Teste et al.

AbstractThis book provides sampling designs for measuring species richness and diversity, patterns of plant diversity, species-environment relationships, and species distributions in complex landscapes and natural ecosystems. Part I introduces the problem: plant diversity studies are difficult to design and conduct in part because of the history and ...
