In this paper we study in what order a crawler should visit the URLs it has seen, to obtain more "important" pages first. Obtaining important rapidly can be very useful when cannot entire Web reasonable amount of time. We define several importance metrics, ordering schemes, and performance evaluation measures for problem. also experimentally evaluate schemes on Stanford University Web. Our results show that with good scheme significantly faster than one without.
Acaryochloris marina is a unique cyanobacterium that able to produce chlorophyll d as its primary photosynthetic pigment and thus efficiently use far-red light for photosynthesis. species have been isolated from marine environments in association with other oxygenic phototrophs, which may driven the niche-filling introduction of d. To investigate these adaptations, we sequenced complete genome A. marina. The DNA content composed 8.3 million base pairs, among largest bacterial genomes far....
Pterygoplichthys punctatus and P. weberi, new species, are unique among hypostomines in having a medially divided buccal papilla. The two species can be separated from one another by color (small spots punctatus, large weberi), condition of the papilla (deeply at all ages vs. shallowly adults lateral keel odontodes (fairly short directed posteriorly almost laterally body width (SL/cleithral 3.6-4.0 3.3-3.4 weberi). is known rio Madeira drainage Urubu Brazil has published, but unconfirmed...
The Paracanthocobitis zonalternans species complex is revised based on analysis of morphological and molecular data. Three new species, P. nigrolineata, marmorata, triangula are described, phuketensis removed from synonymy. All described morphologically, geographic ranges delimited, relationships discussed for those which data (cytochrome c oxidase subunit 1 - COI) available. In view the similarities some a surprising result this study was moderately large genetic distances among species....
An improved and expanded nomenclature for genetic sequences is introduced that corresponds with a ranking of the reliability taxonomic identification source specimens. This an advancement "Genetypes" naming system, which some have been reluctant to adopt because use "type" suffix in terminology. In new nomenclature, are labeled "genseq," followed by (e.g., 1 if sequence from primary type), name genes were derived genseq-1 16S, COI). The numbered provides indication likely voucher. Included...
Acantopsis (Cobitidae) is revised based on analysis of morphological and molecular data. Four the six available names, A. dialuzona, spectabilis, octoactinotos, thiemmedhi, are valid, three new species, rungthipae, dinema, ioa, described. All species described morphologically, distributions mapped, relationships discussed for those which data (CO1, RAG1) available. Labial barbels, color pattern, meristic counts most diagnostic features. Although long snout perhaps emblematic attribute genus,...
Despite the fact that heliobacteria are only phototrophic representatives of bacterial phylum Firmicutes, genomic analyses these organisms have yet to be reported. Here we describe complete sequence and analysis genome Heliobacterium modesticaldum, a thermophilic species belonging this unique group phototrophs. The is single 3.1-Mb circular chromosome containing 3,138 open reading frames. As suspected from physiological studies failed show photoautotrophic growth, genes encoding enzymes for...
Abstract North America exhibits the most diverse freshwater fish fauna among temperate regions of world. Species diversity is concentrated in Central Highlands, drained by Mississippi, Gulf Slope and Atlantic river systems. Previous investigations Highlands biogeography have led to conflicting hypotheses involving dispersal vicariance explain distribution fauna. In this investigation predictions pre‐Pleistocene hypothesis are tested with a phylogeographic analysis percid species Percina...
Crayfishes and shrimps (Decapoda) are conspicuous components of the aquatic environments Illinois. Although only 23 species known to inhabit state, they among our largest invertebrates often present in large populations.
The unicellular diazotrophic cyanobacterium Cyanothece sp. ATCC 51142 (Cyanothece 51142) is able to grow aerobically under nitrogen-fixing conditions with alternating light-dark cycles or continuous illumination. This study investigated the effects of carbon and nitrogen sources on metabolism via (13)C-assisted metabolite analysis biochemical measurements. Under light (50 mumol photons m(-2) s(-1)) conditions, we found that glycerol addition promoted aerobic biomass growth (by twofold)...
Truncation of the algal light-harvesting antenna is expected to enhance photosynthetic productivity. The wild type and three mutant strains Synechocystis sp. strain 6803 with a progressively smaller phycobilisome were examined under different light CO(2) conditions. Surprisingly, such truncation resulted in decreased whole-culture productivity for this cyanobacterium.
The tribes Contradentini and Rectidentini (Unionidae) comprise a diverse clade of freshwater mussels endemic to South-east Asia. Our understanding the diversity phylogeny this radiation has improved dramatically in recent years, but systematic transformation not yet benefited from comprehensive museum sampling or phylogenomic methods. A synthetic taxonomic revision Contradentini+Rectidentini that leverages these useful accessible methods is needed. We set out (1) generate reconstruction...
