Inference of RNA decay rate from transcriptional profiling highlights the regulatory programs of Alzheimer's disease. [PDF]

, 2017
The abundance of mRNA is mainly determined by the rates of RNA transcription and decay. Here, we present a method for unbiased estimation of differential mRNA decay rate from RNA-sequencing data by modeling the kinetics of mRNA metabolism.

Assessing bias in aerial surveys for cetaceans: Results from experiments conducted with the franciscana dolphin

Frontiers in Marine Science, 2022
Line transect aerial surveys are widely used for estimating abundance of biological populations, including threatened species. However, estimates obtained with data collected from aircraft are often underestimated because of visibility bias and bias in ...

Chemical abundances of LINER galaxies – nitrogen abundance estimations

Monthly Notices of the Royal Astronomical Society
ABSTRACT In this work, we investigated the nitrogen and oxygen abundances in a sample of galaxies with Low Ionization Nuclear Emission Regions (LINERs) in their nucleus. Optical spectroscopic data (3600 – 10 000 Å) of 40 LINERs from the Mapping Nearby Galaxies (MaNGAs) survey were considered.

Daily pattern of flight activity of Aedes albifasciatus in Central Argentina

Memorias do Instituto Oswaldo Cruz, 1995
Aedes albifasciatus is an important common mosquito in Central Argentina. Its a confirmed vector of the Western Equine Encephalitis and is responsible for loss of milk production in dairy cattle during peak populations.

Robustness of close‐kin mark–recapture estimators to dispersal limitation and spatially varying sampling probabilities

Ecology and Evolution, 2020
Close‐kin mark–recapture (CKMR) is a method for estimating abundance and vital rates from kinship relationships observed in genetic samples. CKMR inference only requires animals to be sampled once (e.g., lethally), potentially widening the scope of ...

Estimating abundance of an elusive cetacean in a complex environment: Harbor porpoises (Phocoena phocoena) in inland waters of Southeast Alaska

Frontiers in Marine Science, 2022
The harbor porpoise (Phocoena phocoena) is common in temperate waters of the eastern North Pacific Ocean, including Southeast Alaska inland waters, a complex environment comprised of open waterways, narrow channels, and inlets.

Assessing the efficacy and cost‐effectiveness of integrating autonomous recording units and point‐count surveys for population monitoring of northern bobwhite (Colinus virginianus)

Ecological Solutions and Evidence
Autonomous recording units (ARUs) have emerged as a useful tool for monitoring a wide range of acoustically signalling wildlife species in a cost‐effective manner, but estimating abundance from acoustic data can be challenging.

Derivation of globally averaged lunar heat flow from the local heat flow values and the Thorium distribution at the surface: expected improvement by the LUNAR-A Mission [PDF]

, 2001
The relationship between the Th abundance and the heat flow data of the Apollo sites and the LUANR-A sites, where the Th concentrations are in the wide range from 1 ppm to 6 ppm, will allow for a more precise estimation of the averaged heat flow ...

Bracken: estimating species abundance in metagenomics data

PeerJ Computer Science, 2016
Metagenomic experiments attempt to characterize microbial communities using high-throughput DNA sequencing. Identification of the microorganisms in a sample provides information about the genetic profile, population structure, and role of microorganisms within an environment.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
