Investigating the phylogenetic history of toxin tolerance in mushroom‐feeding Drosophila

open access: yesEcology and Evolution, 2023
Understanding how and when key novel adaptations evolved is a central goal of evolutionary biology. Within the immigrans‐tripunctata radiation of Drosophila, many mushroom‐feeding species are tolerant of host toxins, such as cyclopeptides, that are ...

Radiation tolerance of several lithium greases

open access: yesFushe yanjiu yu fushe gongyi xuebao, 2021
Using γ ray to irradiat six types of lithium grease, the color of these greases was observed to change, and the degree of change was found to be positively correlated with an increase in the absorbed dose.

Tolerance to Gamma Radiation in the Tardigrade Hypsibius dujardini from Embryo to Adult Correlate Inversely with Cellular Proliferation. [PDF]

open access: yesPLoS ONE, 2015
Tardigrades are highly tolerant to desiccation and ionizing radiation but the mechanisms of this tolerance are not well understood. In this paper, we report studies on dose responses of adults and eggs of the tardigrade Hypsibius dujardini exposed to ...
