Phylogenetic Approaches for Describing and Comparing the Diversity of Microbial Communities

It is shown that information gained from analysis of DNA sequences provides the basis for statistical analysis of communities in ways that advance inferences about the processes that may govern the compositions and functions of microbial communities.
Seasonal Dynamics of Previously Unknown Fungal Lineages in Tundra Soils
It is shown that tundra soil microbial biomass reaches its annual peak under snow, and that fungi account for most of the biomass.
Bumblebee flight distances in relation to the forage landscape.

- 1 March 2008
To this knowledge, this is the first time that empirical data on foraging distances and forage availability, at this resolution and scale, have been collected and combined for bumblebees.
Rates of mitochondrial DNA evolution in sharks are slow compared with mammals
Examination of mtDNA sequence variation for 13 species of sharks from two orders that are well represented in the fossil record to test the constancy hypothesis finds differences in mtDNA substitution rates among taxa indicate that it is inappropriate to use a calibration for one group to estimate divergence times or demographic parameters for another group.
Microbial Community Succession in an Unvegetated, Recently Deglaciated Soil
It is found that evenness, phylogenetic diversity, and the number of phylotypes were lowest in the youngest soils, increased in the intermediate aged soils, and plateaued in the oldest soils, while soil N pools significantly increased with soil age, perhaps as a result of the activity of the N-fixing Cyanobacteria.
Marked genetic divergence among sky island populations of Sedum lanceolatum (Crassulaceae) in the Rocky Mountains.
Genetic differentiation in S. lanceolatum was most likely a product of short-distance elevational migration in response to climate change, low seed dispersal, and vegetative reproduction, and paleoclimatic cycles were probably a major factor preserving genetic variation and promoting divergence in high-elevation flora of the Rocky Mountains.
Phylogeny of elasmobranchs based on LSU and SSU ribosomal RNA genes.
Marine incursion into South America
The Amazon basin harbours the most diverse assemblage of freshwater fishes in the world, including a disproportionately large number of marine-derived groups, such as stingrays, flatfishes,…
