Dispersal limitations matter for microbial morphospecies.
In contrast with macroorganisms, whose geographical ranges are typically restricted, many microbial species appear to have cosmopolitan distributions. This observation has been explained as a consequence of ubiquitous dispersal caused by the enormous population sizes of microbial species. Recently, this "everything is everywhere, but, the environment selects" theory has been challenged by the d...
متن کاملComment on "Dispersal limitations matter for microbial morphospecies".
Telford et al. (Brevia, 19 May 2006, p. 1015) reported that freshwater diatoms exhibit regional-scale richness-pH relationships that depend substantially on regional habitat availability. On this basis, the authors argued that, despite their microscopic size, diatoms are not ubiquitously dispersed. Here, I describe my demonstration that their primary evidence against the ubiquitous dispersal hy...
متن کاملMorphospecies and Taxonomic Species Comparison for Hymenoptera
The use of morphospecies as surrogates for taxonomic species has been proposed as an alternative to overcome the identification difficulties associated with many invertebrate studies, such as biodiversity surveys. Hymenoptera specimens were collected by beating and pitfall traps, and were separated into morphospecies by a non-specialist with no prior training, and later identified by an expert ...
متن کاملPotential and limitations of BIOLOG for microbial community analysis
Characterization of community-level substrate utilization via incubation of environmental samples in BIOLOG microplates has been increasingly applied in many areas of microbial ecology. The easily-produced multivariate profile allows for intensive spatial and temporal analysis of microbial communities, and it is a sensitive and reproducible tool for characterizing microbial communities. This wo...
متن کاملThe Current Conventions for Designating Microbial Species – Strengths and Limitations
RECONCILING MICROBIAL SYSTEMATICS & GENOMICS Microorganisms are fantastically diverse, both genetically and phenotypically. The amount and depth of genetic diversity represented among the named microbial species is greater than that represented among the animals and plants combined. If the distinctions and testing in use today could be applied to all microorganisms (even those that cannot be gr...
