The co-dispersal strategy of (Verrucariaceae) shapes an unusual lichen population structure.

The reproduction and dispersal strategies of lichens play a major role in shaping their population structure and photobiont diversity. Sexual reproduction, which is common, leads to high lichen genetic diversity and low photobiont selectivity. However, the lichen genus adopts a special co-dispersal model in which algal cells from the photobiont and ascospores from the mycobiont are released together into the environment.

CX43 and oxidative stress are the targets of BCB staining to predict the developmental potential of buffalo oocytes.
