Environmental variables, habitat discontinuity and life history shaping the genetic structure of Pomatoschistus marmoratus [PDF]
Coastal lagoons are semi-isolated ecosystems exposed to wide fluctuations of environmental conditions and showing habitat fragmentation. These features may play an important role in separating species into different populations, even at small spatial

Excited States of Proton-bound DNA/RNA Base Homo-dimers: Pyrimidines [PDF]
We are presenting the electronic photo fragment spectra of the protonated pyrimidine DNA bases homo-dimers. Only the thymine dimer exhibits a well structured vibrational progression, while protonated monomer shows broad vibrational bands. This shows that

Apoptosis in mouse fetal and neonatal oocytes during meiotic prophase one [PDF]
Background The vast majority of oocytes formed in the fetal ovary do not survive beyond birth. Possible reasons for their loss include the elimination of non-viable genetic constitutions arising through meiosis, however, the ...
