Pollinator constancy and survival of rare species

Oecologia, 1975
A Markov model of pollinator activity is used to study the effect of constancy on rare plant species. Roughly, constancy is the tendency of the pollinator to continue searching for a flower of the species last visited. The model involves and abundant plant speciesA and two uncommon plant species,B andC, where the pollinator does not distinguish ...

The population ecology of rare species

Journal of Fish Biology, 1990
There is no general theory of rarity, although one is sorely needed both to understand population dynamics and to determine conservation priorities. Here we suggest some of the strands that might be woven into such a theory. They include relationships between local abundance, geographic range size and body size of species, and the determinants of ...

Rare and emerging Candida species

Current Fungal Infection Reports, 2009
With changes in the medical and surgical management of patients over the past 30 years, fungi have emerged as a major cause of human disease. Of the disseminated mycoses, candidiasis remains the most prevalent, with Candida albicans causing more invasive infections than any other fungus.
