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.

The Solar Argon Abundance [PDF]

open access: yes, 2007
The solar argon abundance cannot be directly derived by spectroscopic observations of the solar photosphere. The solar Ar abundance is evaluated from solar wind measurements, nucleosynthetic arguments, observations of B stars, HII regions, planetary ...

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.

Chemical tagging can work: Identification of stellar phase-space structures purely by chemical-abundance similarity [PDF]

open access: yes, 2016
Chemical tagging promises to use detailed abundance measurements to identify spatially separated stars that were in fact born together (in the same molecular cloud), long ago.

Comparing methods to estimate feral burro abundance

open access: yesWildlife Society Bulletin, 2023
Obtaining precise and unbiased estimates of feral burro (Equus asinus) abundance in the western United States is challenging due to their cryptic pelage and the rugged terrain they inhabit. Management agencies employ helicopter‐based, simultaneous double‐

The Void Abundance with Non-Gaussian Primordial Perturbations [PDF]

open access: yes, 2008
We use a Press-Schechter-like calculation to study how the abundance of voids changes in models with non-Gaussian initial conditions. While a positive skewness increases the cluster abundance, a negative skewness does the same for the void abundance.
