Proteogenomic basis for ecological divergence of closely related bacteria in natural acidophilic microbial communities.
Bacterial species concepts are controversial. More widely accepted is the need to understand how differences in gene content and sequence lead to ecological divergence. To address this relationship in ecosystem context, we investigated links between genotype and ecology of two genotypic groups of Leptospirillum group II bacteria in comprehensively characterized, natural acidophilic biofilm comm...
متن کاملMHC Adaptive Divergence between Closely Related and Sympatric African Cichlids
BACKGROUND The haplochromine cichlid species assemblages of Lake Malawi and Victoria represent some of the most important study systems in evolutionary biology. Identifying adaptive divergence between closely-related species can provide important insights into the processes that may have contributed to these spectacular radiations. Here, we studied a pair of sympatric Lake Malawi species, Pseud...
متن کاملNiche divergence and lineage diversification among closely related Sistrurus rattlesnakes.
Comparing niche divergence among closely related taxa can yield important insights into the ecological distinctiveness of genetically similar forms, and identify the processes that are responsible for diversification in such organisms. Here, we apply newly developed techniques for analysing niche divergence to assess how ecologically distinct a group of closely related rattlesnakes (Sistrurus s...
متن کاملToxicity of cadmium and zinc to the cercarial activity of Diplostomum spathaceum (Trematoda: Diplostomidae).
The toxicity of cadmium and zinc at concentrations ranging from 0.1 to 100 microg/l was investigated against the activity of Diplostomum spathaceum (Rudolphi, 1819) cercariae. Over a 24 h exposure period a significant reduction in cercarial activity occurred in solutions of cadmium, zinc, and a mixture of cadmium and zinc at all concentrations. Reduced cercarial activity also occurred in all to...
متن کاملThe life-cycle of Diplostomum baeri eucaliae n. subsp. (Trematoda: Strigeida).
many brook stickleback, Eucalia inconstans, from the English Coulee, a small stream in Grand Forks, were found infected with an unrecorded species of diplostomulum metacercaria; its life cycle has been reported in abstract (Hoffman, 1955). In 1953, 51 (82%) of the 62 sticklebacks examined were infected, but in 1955 a much smaller number was infected ; no exact records were kept in 1954 and 1955...
