We cloned and sequenced a portion of chloroplast DNA from the hornwort Anthoceros formosae. A nucleotide sequence of 7556 bp contained structures similar to those of ndhK, ndhC, trnV, trnM, atpE, atpB, rbcL, trnR and accD. The arrangement of these was the same as that of other chloroplast DNA. However, two nonsense codons were located within the putative coding region of rbcL, although they wer...

Limited information exists on the effects of forest management practices on bryophytes, despite their importance to forest ecosystems. We examined short-term responses of ground-layer bryophytes to logging disturbance and creation of edges in mature Pseudotsuga forests of western Washington (USA). The abundance and richness of species were measured in four 1-ha forest aggregates (patches of int...

Bryophytes are poikilohydric in nature and the oldest known land plant. Their striking resistance to microbial attack suggests their inherent production of antibacterial compounds. The antibacterial activity of acetone, ethanol, methanol and hexane extracts of Calymperes erosum C. Mull and Bryum coronatum Schwaegr were investigated against twenty clinically important bacteria pathogens. Agar di...

Retention of trees from the previous generation is one most widespread conservation practices in forests used for timber production. Despite comparatively long history this approach Europe, there a lack long-term studies on effectiveness retention preserving epiphyte communities. We compared diversity bryophyte and lichen species 20 young forest stands Latvia two assessments, 11 years 18 after ...
