Several processes have been described that could explain geographical variation and speciation within small islands, including fragmentation of populations through volcanic eruptions. Massive landslides, or debris avalanches, could cause similar effects. Here we analyse the potential impact of the 0.8 million‐year‐ago (Ma) Güimar valley debris avalanche on the phylogeography of the lizard Gallotia galloti on the Canary Island...

Pathogens transmitted by ticks include Borrelia , Anaplasma and Babesia . Although ticks may harbour both pathogenic and non‐pathogenic microflora, little is known about how the diversity of the microflora within ticks may influence the transmission of pathogens. To begi...
