Biodiversity assessment of tropical taxa is hampered by their tremendous richness, which leads to large numbers of singletons and incomplete inventories in survey studies. Species estimators can be used for assessment of alpha diversity, but calculation of beta diversity is hampered by pseudo-turnover of species in undersampled plots. To assess the impact of unseen species, we investigated diff...

Estimating abundance or biomass using eDNA metabarcoding is a powerful emerging tool that may provide an alternative to conventional laborious methods for biological monitoring. However, inferring aquatic macroorganism concentrations remains challenging, especially in lotic environments, because of several potential confounding factors. In this study, we tested whether quantitative uses interna...

A parameter estimation procedure was established to extract physical parameters related to chemical vapor deposition ~CVD! processes, which consists of in situ experimental data collection and computational analysis. Specifically, mass-transport behavior in an up-flow cold-wall CVD reactor was monitored using in situ Raman spectroscopy. A two-dimensional axisymmetric model of the reactor was de...

sustainable range management needs the accurate estimation yield and determining of grazing capacity in rangelands. it is easy to obtain yield estimation with indirect methods. for this purpose, the relation between cover and forage yield of range species were studied in steppic rangelands of yazd. measurements of cover and forage yield were carried out with plot area and clipping and weighting...

Estimation of growth curves of poultry species is of particular importance in animal science. This study aims at fitting hierarchical Gompertz growth curve to Japanese quails body weight data obtained from hatching to 56 days of age weekly. The model involved a random animal effect as well as sex and line effects in asymptotic weight parameters. Model parameters were estimated via Bayesian meth...

The Arctic is warming at twice the rate of the rest of the world. This impacts Arctic species both directly, through increased temperatures, and indirectly, through structural changes in their habitats. Species are expected to exhibit idiosyncratic responses to structural change, which calls for detailed investigations at the species and community level. Here, we investigate how arthropod assem...

This paper provides an overview of the BPP program, which is a Bayesian MCMC program for analysis of multi-locus genomic sequence data under the multispecies coalescent model. An example dataset of five nuclear loci from the East Asian brown frogs is used to illustrate four different analyses, including estimation of parameters under the multispecies coalescent model on a fixed species phylogen...

A malware phylogeny model is an estimation of the derivation relationships between a set of species of malware. Systems that construct phylogeny models are expected to be useful for malware analysts. While several different phylogeny construction systems have been proposed, little is known about effective ways of evaluating and comparing them. Little is also known about the consistency of their...
