Evolution of Animal Parasitism in Nematodes of the Suborder Spirurina. [PDF]

open access: yesEcol Evol
This study reconstructs the evolutionary history of parasitism in Spirurina by integrating ancestral state reconstruction (ASR) with a comprehensive phylogenetic framework. Our analyses reveal clear patterns of hostswitching and major transitions in host associations, providing the first broad evolutionary perspective on parasitism within this group ...

Quantitative assessment of the dispersal of soil-dwelling oribatid mites via rodents in restored heathlands. [PDF]

open access: yesEcol Evol, 2022
Heathland restoration using topsoil removal provides an ideal scenario to study colonization processes of soil fauna. We quantitatively assessed passive dispersal of oribatid mites via phoresy using small rodents and compared it to other reported host groups.

Isolation and Characterization of Yeasts Able to Assimilate Sugarcane Bagasse Hemicellulosic Hydrolysate and Produce Xylitol Associated with Veturius transversus (Passalidae, Coleoptera, and Insecta). [PDF]

open access: yesInt J Microbiol, 2017
Yeasts are an important component of insect gut microbial content, playing roles such as degradation of polymers and toxic compounds, biological control, and hormone, vitamin, and digestive enzyme production. The xylophagous beetle gut is a hyperdiverse habitat and a potential source of new species with industrial abilities such as enzyme production ...
