Variability in species richness and guild structure in two species-rich grasslands

Folia Geobotanica et Phytotaxonomica, 1995
It has been suggested that variation in the proportion of species in guilds (=guild proportionality) indicates community structuring by guilds in biotic communities. This hypothesis was tested on a subthermophilous grassland and a mesotrophic meadow at a scale of 0.09 m2 based on a five-year data set.

Assessment of tree species richness as a surrogate for macrofungal species richness

Biological Conservation, 2005
Abstract Attempts to understand and conserve biodiversity are hampered by a lack of information about many taxonomic groups, particularly those groups that are the most species rich. Although fungi are ubiquitous and play an important role in decomposition, nutrient cycling and nutrient uptake, little is known about fungal diversity, as fungi are ...

Consumer Species Richness and Autotrophic Biomass

Ecology, 1998
We tested whether standing autotrophic (unicellular algal) biomass is sensitive to variation in initial consumer (nondecomposer, heterotrophic protistan) diversity in experimental microbial microcosms. Our results showed a strong, negative relationship between autotrophic biomass and consumer species richness.

Lower Species Richness in Dioecious Clades

The American Naturalist, 2000
Despite the extensive research on the potential benefits of dioecy to individuals, little is known about the long-term success of dioecious lineages in relation to their hermaphroditic or monoecious relatives. This study reports on the evolutionary success of worldwide dioecious flora in light of recent phylogenetic work by performing sister-group ...
