Causes of B chromosome variant substitution in the grasshopper Eyprepocnemis plorans
Manrique-Poyato, María Inmaculada
; Muñoz-Pajares, Antonio Jesús; Loreto, Vilma; López-León, María Dolores; Cabrero-Hurtado, Josefa; Martínez-Camacho, Juan Pedro[et al.] (Springer, 2006)
We have analysed B chromosome frequency for three consecutive years, B transmission rate at population and individual levels, clutch size, egg fertility and embryoYadult viability in a natural population of the ... -
Detection of B chromosomes in interphase hemolymph nuclei from living specimens of the grasshopper Eyprepocnemis plorans
Cabrero-Hurtado, Josefa; Manrique-Poyato, María Inmaculada; Martínez Camacho, Juan Pedro (Karger, 2006)
The two most important evolutionary properties of B chromosomes are their transmission rate (which suggests their selfishness when significantly higher than 0.5) and their net effects on carrier fitness (usually negative ... -
Effects of B Chromosomes on Egg Fertility and Clutch Size in the Grasshopper Eyprepocnemis plorans
Bakkali, Mohammed; Manrique-Poyato, María Inmaculada; López-León, María Dolores; Perfetti-Álvarez, Francisco; Cabrero-Hurtado, Josefa; Martínez-Camacho, Juan Pedro[et al.] (Pensoft, 2010)
We analyse here three components of reproductive success (egg fertility, egg clutch size and embryo clutch size) in several temporal samples from different Spanish and Moroccan populations of the grasshopper Eyprepocnemis ... -
Nucleolus size varies with sex, ploidy and gene dosage in insects
Montiel-Jiménez, Eugenia Elisabeth; Manrique-Poyato, María Inmaculada; Rocha-Sánchez, Sonia María; López-León, María Dolores; Cabrero-Hurtado, Josefa; Perfectti-Álvarez, Francisco; Martínez-Camacho, Juan Pedro[et al.] (Wiley, 2012)
The nucleolus constitutes a cytologically visible phenotype for ribosomal DNA (rDNA). Nucleolar size, as determined by silver staining, is a good indicator of cell proliferation rate and biosynthetic activity. Nevertheless, ...
