DNA barcoding the genus Chara: molecular evidence recovers fewer taxa than the classical morphological approach.
Charophytes (Charales) are benthic algae with a complex morphology. They are vulnerable to ecosystem changes, such as eutrophication, and are red-listed in many countries. Accurate identification of Chara species is critical for understanding their diversity and for documenting changes in species distribution. Species delineation is, however, complicated, because of high phenotypic plasticity. ...
متن کاملChara Technical Report
In response to the accumulation of the first substantial collection of observational data from the CHARA Array, obtained during the fall of 2001, a series of Mathcad programs has been developed as a means for reducing these data to calibrated visibilities. The Mathcad tools developed to date include routines that calculate estimated visibilities for single and double stars, ephemeredes from bin...
متن کاملMicrospectrophotometric Analysis of Nuclear Dna in Chara Zeylanica
Microspectrophotometric analysis of the DNA content of nuclei in various parts of Chara zeylanica Willd. revealed that the amount of DNA in the nucleus of an internodal cell equals twice the amount of DNA in the nucleus of a sperm, while the half-anaphase stage of the same nodal cells contains the same amount of DNA as the nuclei of the male gametes. The DNA content of the nuclei of internodal ...
متن کاملStarspot Imaging with the CHARA Array
We present the first results of a starspot interferometric imaging program targeting the chromospherically active giant Lambda Andromedae. Our images are constructed using a new starspot model that incorporates a power limb darkening law and starspot foreshortening. The model solutions are determined through χ minimization of observed squared visibilities, triple amplitudes and closure phase. M...
متن کاملPlasmalemma Voltage Noise in Chara corallina.
Voltage noise analysis is applied to plasmalemma ion transport in Chara corallina. There is a component in the noise power spectrum that is probably associated with current fluctuations within passive transport channels, and another component that may be associated either with fluctuations in the number of open channels, or with active transport. The data allow the calculation of time constants...
