Consumptive and nonconsumptive effects of omnivorous tadpoles on aquatic invertebrate communities

open access: yesEcosphere, 2023
Consumptive effects (CEs) of predation have been well‐studied in most aquatic systems, but nonconsumptive effects (NCEs) on prey have only recently received limited attention.

Imperfect Estimation of Lepeophtheirus salmonis Abundance and Its Impact on Salmon Lice Treatment on Atlantic Salmon Farms

open access: yesFrontiers in Marine Science, 2021
Accurate monitoring of sea lice levels on salmon farms is critical to the efficient management of louse infestation, as decisions around whether and when to apply treatment depend on an estimation of abundance.

Determining cell-type abundance and expression from bulk tissues with digital cytometry

open access: yesNature Biotechnology, 2019
Single-cell RNA-sequencing has emerged as a powerful technique for characterizing cellular heterogeneity, but it is currently impractical on large sample cohorts and cannot be applied to fixed specimens collected as part of routine clinical care.

Nebular Abundance Errors [PDF]

open access: yes, 1997
The errors inherent to the use of the standard "ionization correction factor" ("i_CF") method of calculating nebular conditions and relative abundances of H, He, N, O, Ne, S, and Ar in emission line nebulae have been investigated under conditions typical

The abundance, biomass, and distribution of ants on Earth

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2022
Significance The astounding ubiquity of ants has prompted many naturalists to contemplate their exact number on Earth, but systematic and empirically derived estimates are lacking.

Biogeography and predictors of wildlife killed on roads at peninsular Florida State Parks

open access: yesEcology and Evolution, 2021
Wildlife‐vehicle collisions (WVCs) are a major source of wildlife mortality and should affect regional wildlife diversity and abundance, yet most WVC studies are locally scaled.

Estimating the population abundance of tissue-infiltrating immune and stromal cell populations using gene expression

open access: yesGenome Biology, 2016
We introduce the Microenvironment Cell Populations-counter (MCP-counter) method, which allows the robust quantification of the absolute abundance of eight immune and two stromal cell populations in heterogeneous tissues from transcriptomic data.

Soil Properties and the Abundance of Ironwood (Eusideroxylon zwageri Teijsm.& Binn.) Varieties in Jambi, Indonesia

open access: yesJurnal Manajemen Hutan Tropika, 2015
Two series of a study on the correlation between soil properties and distribution of ironwood (Eusideroxylon zwageri Teijsm.&Binn.) varieties had been conducted in Senami, a natural foreststand, Jambi,Indonesia.

The Abundance of Interstellar Nitrogen [PDF]

open access: yes, 1997
Using the HST Goddard High Resolution Spectrograph (GHRS), we have obtained high S/N echelle observations of the weak interstellar N I 1160, 1161 A absorption doublet toward the stars Gamma Cas, Lambda Ori, Iota Ori, Kappa Ori, Delta Sco, and Kappa Sco ...

Bracken: estimating species abundance in metagenomics data

open access: yesbioRxiv, 2016
We describe a new, highly accurate statistical method that computes the abundance of species in DNA sequences from a metagenomics sample. Bracken (Bayesian Reestimation of Abundance after Classification with KrakEN) uses the taxonomy labels assigned by ...
