INCORPORATING THE SOIL COMMUNITY INTO PLANT POPULATION DYNAMICS : THE UTILITY OF THE FEEDBACK APPROACH
TLDR
Using a simple experimental protocol, substantial negative feedback on plant growth is found through the soil community, suggesting that it may be involved in the maintenance of plant species diversity.
Social Organization and Parasite Risk in Mammals: Integrating Theory and Empirical Studies
TLDR
The effects of host density and social contacts on parasite spread and the importance of promiscuity and mating structure for the spread and evolution of sexually transmitted diseases are reviewed.
Host-Dependent Sporulation and Species Diversity of Arbuscular Mycorrhizal Fungi in a Mown Grassland
TLDR
Spore counts in field soil and estimates from sorghum trap cultures showed that the association of AM fungi with particular host plants in the field was positively correlated with the sporulation rates observed on those hosts in the microcosm experiments, suggesting host-dependent differences in fungal growth rates.
SEXUALLY TRANSMITTED DISEASES IN ANIMALS: ECOLOGICAL AND EVOLUTIONARY IMPLICATIONS
TLDR
Comparison of the characteristics of sexually transmitted mammalian diseases with those that are transmitted by non-sexual means showed that STDs cause less mortality, are longer-lived in their hosts, are less likely to invoke strong immune responses, have narrower host-ranges, and show less fluctuation in prevalence over time.
Evolution in closely adjacent plant populations
TLDR
It is invalid to conclude that a monotonic cline for reproductive isolation gives a priori evidence of its evolution in allopatry, but the existence of inverse clines in isolating mechanisms strongly suggests the evolution of isolation in sympatry.
Species Coexistence and Pathogens with Frequency‐Dependent Transmission
TLDR
The results show that if there is frequency‐dependent transmission, a host can be rescued from pathogen‐mediated extinction by the presence of a second host with which it shares a pathogen.
DISEASE SPREAD AND POPULATION DYNAMICS OF ANTHER-SMUT INFECTION OF SILENE ALBA CAUSED BY THE FUNGUS USTILAGO VIOLACEA
TLDR
It was revealed that only 4'%o of plants healthy in one year were diseased the following year, indicating that floral infection does not always lead to successful systemic infection.
Promiscuity and the primate immune system.
TLDR
White blood cell counts were significantly greater in species where females have more mating partners, indicating that the risk of sexually transmitted disease is likely to be a major factor leading to systematic differences in the primate immune system.
