Atradidymella muscivora gen. et sp. nov. (Pleosporales) and its anamorph Phoma muscivora sp. nov.: A new pleomorphic pathogen of boreal bryophytes
Download2009
During a survey of bryophilous fungi from boreal and montane habitats, 12 isolates of a hitherto unknown plant pathogenic member of the Pleosporales were recovered from Aulacomnium palustre , Hylocomium splendens , and Polytrichum juniperinum , and described as Atradidymella muscivora gen. et sp....

Autoregulation of RNA helicase expression in response to temperature stress in Synechocystis spCC 6803
Download2012
Owttrim, George W., Chamot, Danuta, Rosana, Albert R. R.
RNA helicases are ubiquitous enzymes whose modification of RNA secondary structure is known to regulate RNA function. The pathways controlling RNA helicase expression, however, have not been well characterized. Expression of the cyanobacterial RNA helicase, crhR, is regulated in response to...

Vickaryous, M. K., Lavigne, J. M., Currie, P. J., Gardner, J. D., Ryan, M. J.
A new microvertebrate site (≈72 Ma) in the Horseshoe Canyon Formation, south-central Alberta, is a deflational lag in interbedded silty shales. The site represents deposition on a waterlogged coastal plain ≈100 km to the west of the Bearpaw Sea. Approximately two-thirds (n=224) of the 388...

Cohen, M. B., Aguda, R. M., Bottrell, D. G., Gould, F. L., Litsinger, J. A., Theunis, W., Peferoen, M., Cruz, W. T., Decock, C., Lambert, B.
Abstract: Bacillus thuringiensis Berliner isolates were detected in 57% of 801 samples of rice grain dust, soil, rice field arthropods, and miscellaneous habitats (rice straw compost and mammal faeces) collected at 100 sites in the Philippines. The collection yielded 3950 isolates of B....

BacMap is an interactive visual database containing fully labeled, zoomable and searchable chromosome maps from more than 170 bacterial (archaebacterial and eubacterial) species. It uses a recently developed visualization tool (CGView) to generate highresolution circular genome maps from sequence...

Beardia vancouverensis gen. et sp. nov. (Juglandaceae): Permineralized fruits from the Eocene of British Columbia
Download2006
Mindell, R.A., Stockey, R.A., Elliott, L.L.
Large numbers of permineralized juglandaceous fruits were identified in calcareous nodules from the Eocene Appian Way locality on Vancouver Island, British Columbia, Canada. The fruits, small dorsiventrally flattened nutlets, 4.5–7.0 mm long and 5.5–9.0 3 3–5 mm in diameter, were studied using...

Beyond resource selection: emergent spatio-temporal distributions from animal movements and stigmergent interactions
Download2022-03-30
Jonathan R. Potts, Valeria Giunta, Mark A. Lewis
A principal concern of ecological research is to unveil the causes behind observed spatio-temporal distributions of species. A key tactic is to correlate observed locations with environmental features, in the form of resource selection functions or other correlative species distribution models....
