Water vapour uptake from the atmosphere and critical equilibrium humidity of a feather mite
@article{Gaede1987WaterVU, title={Water vapour uptake from the atmosphere and critical equilibrium humidity of a feather mite}, author={Karl Gaede and Willi Kn{\"u}lle}, journal={Experimental \& Applied Acarology}, year={1987}, volume={3}, pages={45-52} }
The feather miteProctophyllodes troncatus Robin takes up water vapour from subsaturated atmospheres down to relative humidities between 55% and 60%. Vapour uptake increases with rising humidity of the surrounding air and the time to attain maximum water gain decreases.

Diversity of Feather Mites (Acari: Astigmata) on Darwin's Finches
- Biology, Environmental ScienceThe Journal of parasitology

Host body mass was significantly correlated with mean feather mite abundance across 7 of 8 well-sampled species of finches, and Certhidea olivacea, the smallest species, did not fit this pattern and had a disproportionately high number of mites for its body mass.

It is suggested that ectosymbionts of warm-blooded animals may be highly sensitive to climatic variation and become less abundant under stressful environmental conditions, providing empirical evidence of the decline of specialized biotic interactions among animal species at high elevations.

Differential survival and dispersal of avian feather mites with contrasting host specificities

Measure and compared survival probability and rate of dispersal to determine how these traits differ between two species of feather mites in the same genus and discovered that while the host generalist mite survived longer, the host specialist mite dispersed more quickly.
Is permanent parasitism reversible?--critical evidence from early evolution of house dust mites.

There is conclusive evidence that house dust mites, a group of medically important free-living organisms, evolved from permanent parasites of warm-blooded vertebrates, and it is proposed that parasitic ancestors of pyroglyphids shifted to nests of vertebrates.
Divergent host phenotypes create opportunities and constraints on the distribution of two wing‐dwelling feather mites

The distribution of two feather mite species, Proctophyllodes sylviae and Trouessartia bifurcata, among blackcaps Sylvia atricapilla wintering in southern Spain during six winters is studied to expand the understanding of bird–mite interactions and emphasizes the role of host phenotypic divergence in the diversification of symbiotic organisms.

Populations of flour mites reared at 95.5 and 75% RH contained respectively about 70 and 66% of water, the equilibrium moisture contents at these humidities, but increases did not lead to steady equilibrium levels; instead, they were superseded by decreases after about a day, or less, presumably because fasting weakened the ability to retain moisture.
