Feeding on epibenthic zooplankton by Long‐tailed Ducks: patch structure, profitability, and food web implications

open access: yesEcosphere, 2021
Models of the trophic needs and impacts of mobile predators in food web networks typically do not consider interactions between prey dispersion and threshold prey densities needed for profitable foraging. As a result, the biomass of predators that can be

Fractal-Fractional Caputo Maize Streak Virus Disease Model

open access: yesFractal and Fractional, 2023
Maize is one of the most extensively produced cereals in the world. The maize streak virus primarily infects maize but can also infect over 80 other grass species. Leafhoppers are the primary vectors of the maize streak virus.

Testing Linear Operator Constraints in Functional Response Regression with Incomplete Response Functions. [PDF]

open access: yesElectron J Stat, 2023
Hypothesis testing procedures are developed to assess linear operator constraints in function-on-scalar regression when incomplete functional responses are observed. The approach enables statistical inferences about the shape and other aspects of the functional regression coefficients within a unified framework encompassing three incomplete sampling ...

Functional response estimations of Chrysoperla carnea to different densities of Aphis craccivora and Gynaikothrips ficorum nymphs

open access: yesBrazilian Journal of Biology, 2022
The functional responses of Chrysoperla carnea larvae were evaluated at different seven densities of the 3rd instar nymphs of Aphis craccivora and Gynaikothrips ficorum in order to find out the relationship between predator densities and its prey by the,

HipA-Mediated Phosphorylation of SeqA Does not Affect Replication Initiation in Escherichia coli

open access: yesFrontiers in Microbiology, 2018
The SeqA protein of Escherichia coli is required to prevent immediate re-initiation of chromosome replication from oriC. The SeqA protein is phosphorylated at the serine-36 (Ser36) residue by the HipA kinase.

Serine-Threonine Kinases Encoded by Split hipA Homologs Inhibit Tryptophanyl-tRNA Synthetase

open access: yesmBio, 2019
Type II toxin-antitoxin (TA) modules encode a stable toxin that inhibits cell growth and an unstable protein antitoxin that neutralizes the toxin by direct protein-protein contact.

Bivariate stochastic modeling of functional response with natural mortality [PDF]

open access: yes, 2010
A correction due to Abbott (1925) is the standard method of dealing with control mortality in insect bioassay to estimate the mortality of an insect conditional on control mortality not having occurred.

Neglect of Presence of Bacteria Leads to Inaccurate Growth Parameters of the Oligotrich Ciliate Strombidium sp. During Grazing Experiments on Nanoflagellates

open access: yesFrontiers in Marine Science, 2020
Oligotrich ciliates play a key role in linking microbial food webs to the traditional grazing food chain. Hence, the numerical (growth) and functional (grazing) responses of oligotrich ciliates are very important issues in studies of marine ecosystems ...

Robust Classification of Functional and Quantitative Image Data Using Functional Mixed Models [PDF]

open access: yes, 2012
This paper describes how to perform classification of complex, high-dimensional functional data using the functional mixed model (FMM) framework. The FMM relates a functional response to a set of predictors through functional fixed and random effects ...
