Abstract Seasonal reproduction is widespread among primates but the degree of reproductive synchrony and plasticity can vary, even between closely related species. This study compares dynamics female seasonality in two mouse lemur species, Microcebus murinus M. ravelobensis, Ankarafantsika National Park, Madagascar, across 24 years. We collected 4321 records state from 1033 individual females (...

The symmetric q, t-Catalan polynomial Cn(q, t), which specializes to the Catalan polynomial Cn(q) when t = 1, was defined by Garsia and Haiman in 1994. In 2000, Garsia and Haglund proved the existence of statistics a(π) and b(π) on Dyck paths such that Cn(q, t) = P π qt where the sum is over all n × n Dyck paths. Specializing t = 1 gives Cn(q) = P π q and specializing q = 1 as well gives the us...

We have measured the radial brightness distributions in the disks of three nearby face-on spirals: M 51, NGC 3631, and NGC 4321 (M 100) in the photometric bands B through I, with the addition of the K band for M 51 only. The measurements were made by averaging azimuthally, in three modes, the two-dimensional surface brightness over the disks in photometric images of the objects in each band: (a...

The purpose of this study was to evaluate the homogeneity of Polish populations with respect to STRs chosen as core markers of the Polish Forensic National DNA Intelligence Database, and to provide reference allele frequencies and to explore the genetic interrelationship between Poland and neighboring countries. The allele frequency distribution of 10 STRs included in the SGMplus kit was analyz...

We present TAURUS Fabry-Perot velocity data in Hα emission of the disc of the grand design spiral M 100 (NGC 4321). We have studied the emission spectra of the 200 H ii regions most luminous in Hα, calibrated in luminosity using photometric Hα imaging from the literature. The emission spectra of individual H ii regions were fitted using one or more Gaussian functions, and analyzed in terms of t...
