Regional data refine local abundance models: modeling plant species abundance distributions on the Central Plains
… models developed using locally collected abundance data to regional extents for a native and alien plant species across a portion of the central plains in Colorado. Topographic, remotely sensed, land cover and soil taxonomic predictor variables were used to develop the models. Predicted …

RNA bacteriophages: diversity, abundance, and applications
… databases, it was timely to explore their true abundance in different environments by exploiting advances in the science of bioinformatics. Our method, utilizing specific profile hidden Markov model (HMM) search tools, is described in detail. This work greatly expanded the numbers of +ssRNA …

Pollinator Abundance at Solar Farms in Alberta, Canada
… pollinator habitat to support pollinator abundance. Some solar farms opt for a vegetated substrate beneath solar panels and target mowing to beneath panels. Edges of solar sites experience less frequent vegetation control which could create an edge effect and influence how bees assemble …

Distribution and abundance of soft-sediment intertidal Polychaetes
… about the factors that control the relative abundance of these species. In view of the extensive evidence of the importance of interactions between component species in intertidal communities it is of interest to obtain information that would facilitate future experimental work of such …

Tropical Pyramids: Dung Beetle Richness, Abundance, and Biomass
… soils likely support a higher volume and abundance of scarabs than old soils, but diversity across Amazonia may be similar. I compared beta-diversity of scarab communities across Amazonia. Species rank-abundance curves did not differ among sites whereas volume-abundance distributions and …

Kinematic and Abundance Gradients in the Galactic Disk
… the purpose of investigating the gradients of abundance and velocity dispersion in the galactic disk. The abundance gradient found for these stars is d (Fe/H) /dR = $-$0.017 $\pm$.007 dex/kpc, which is similar to the gradients found in other studies of mixed-age objects. $U$ velocity dispersion …

UNDERSTANDING DIFFERENTIAL ABUNDANCE IN MICROBIAL ECOLOGY USING COMMUNITY STRUCTURE.
… science, agriculture, and medicine. Differential abundance analysis (DAA) is one of the central statistical methods for identifying microbial features that are associated with macroscopic states. Differentially abundant microbial features can broaden the understanding of disease mechanisms and …

Extracting fish abundance indices from recreational fishing competition data
… and consistent enough for the extraction of abundance indices for certain species. Further work on these data may involve the standardisation of CPUE values to account for targeting in the multi-species fishery. With a large number of boat based competitive anglers in the country, there is a …

Relationships between body size, reproduction, and abundance in natural vegetation
… old-field community. A more accurate measure of abundance was obtained by locating random 1 x 1 m plots and counting the number of ramets for each species in the plot. A significant negative relationship was seen between abundance and MRTS. This suggests that the most abundant plants in …

LUMINOSITY DISTRIBUTIONS AND ABUNDANCE TOMOGRAPHY MODELLING OF TYPE IA SUPERNOVAE
… spectroscopic and photometric analysis and abundance stratification modelling of SN 2014J is presented. SN 2014J is a spectroscopically normal type Ia SN with a B band decline rate of 0.95 mag, before correction for extinction. It was located in the dusty starburst galaxy M82, and does not …

Selection of landscapes by male ruffed grouse during peak abundance.
Most research on ruffed grouse (Bonasa umbellus) habitat selection has focused either on habitat structure within their activity centers or characteristics of forest stands containing activity centers. I studied the relationship between landscape configuration and density of male grouse during the …

Analysis of Bacterial Abundance and Species Diversity in Various Soils
… a wide range of nutrient content, microbial abundance and diversity. Many of the microbes viable in soil have practical functions in the agricultural and medical fields while others are pathogenic. Garden topsoil, potting soil, forest soil, compost and manure were the five soil types …

Technologies of abundance : consumer culture, government and the media arts
Arts funding provides one of the clearest examples available of the cybernetic metaphor, that is, the role of cultural policy in hierarchically ranking cultural forms and their publics. Justification for the hierarchical control of the cybernetic apparatus in the national cultural interest takes on …

A Kinematic and Abundance Survey of the Galactic Pole Regions
… combined with published photometry to give a new abundance gradient perpendicular to the galactic plane to z-distances greater than 5 kpc. Additional DDO photometry of bright field stars has been used to calibrate the DDO abundance index against {Fe/H} for metal-poor stars.
