Predicting global numbers of teleomorphic ascomycetes

چکیده

Abstract Sexual reproduction is the basic way to form high genetic diversity and it beneficial in evolution speciation of fungi. The global teleomorphic species Ascomycota has not been estimated. This paper estimates number for sexual ascomycetes based on five different estimation approaches, viz. by numbers described fungi, fungus:substrate ratio, ecological distribution, meta-DNA barcoding or culture-independent studies previous Ascomycota. assumptions were made with currently most accepted, “2.2–3.8 million” estimate results concluding that 90% reproduce sexually. Catalogue Life, Species Fungorum published research used data procurement. average value from all methods 1.86 million, ranging 1.37 2.56 million. However, only around 83,000 have deposited repositories. ratio between predicted 1:22. Therefore, where are undiscovered ascomycetes? undescribed no doubt be found biodiversity hot spots, poorly-studied areas complexes. Other poorly studied niches include extremophiles, lichenicolous human pathogens, marine fungicolous Undescribed present unexamined collections specimen repositories incompletely earlier species. Nomenclatural issues, such as use separate names teleomorph anamorphs, synonyms, conspecific names, illegitimate invalid also affect Interspecies introgression new species, while reduced extinctions.

Transcriptional regulatory circuits: predicting numbers from alphabets.

Transcriptional regulatory circuits govern how cis and trans factors transform signals into messenger RNA (mRNA) expression levels. With advances in quantitative and high-throughput technologies that allow measurement of gene expression state in different conditions, data that can be used to build and test models of transcriptional regulation is being generated at a rapid pace. Here, we review ...

Predicting Social Security numbers from public data.

Information about an individual's place and date of birth can be exploited to predict his or her Social Security number (SSN). Using only publicly available information, we observed a correlation between individuals' SSNs and their birth data and found that for younger cohorts the correlation allows statistical inference of private SSNs. The inferences are made possible by the public availabili...

An empirical study on predicting defect numbers

Defect prediction is an important activity to make software testing processes more targeted and efficient. Many methods have been proposed to predict the defect-proneness of software components using supervised classification techniques in withinand cross-project scenarios. However, very few prior studies address the above issue from the perspective of predictive analytics. How to make an appro...

Predicting Prime Numbers Using Cartesian Genetic Programming

Prime generating polynomial functions are known that can produce sequences of prime numbers (e.g. Euler polynomials). However, polynomials which produce consecutive prime numbers are much more difficult to obtain. In this paper, we propose approaches for both these problems. The first uses Cartesian Genetic Programming (CGP) to directly evolve integer based prime-prediction mathematical formula...
