Revisiting Moran 1996

In a paper published in PNAS in 1996, Nancy Moran showed that endosymbiotic bacterial lineages showed faster rates of evolution of 16S rDNA and increased rate of fixation of deleterious mutations, compared to free-living lineages. These results, Moran concluded, were evidence for the Muller's ratchet phenomenon in combination with mutational bias. Twenty-three years after the … Continue reading Revisiting Moran 1996

Revisiting Bascompte et al. 2003

In a paper published in PNAS in 2003, Jordi Bascompte, Pedro Jordano, Carlos Meli├ín and Jens Olesen investigated the structural organisation of 52 mutualistic networks and found them to be highly nested, resulting in communities centred around a smaller core of interactions. Bascompte and colleagues also found that communities that contained a greater number of … Continue reading Revisiting Bascompte et al. 2003

Revisiting Ebert 1994

In a paper published in Science in 1994, Dieter Ebert showed, using laboratory experiments on a horizontally-transmitted disease in Daphnia, that spore production and infection was lower when the geographic distance between parasite and wild-caught Daphnia host origins were greater. Ebert's findings suggested that parasites were locally adapted and contradicted the hypothesis that co-evolved parasites … Continue reading Revisiting Ebert 1994
