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.

The diurnal water vapour profile within the laminar layer at the leaf surface includes periods withWater vapour values high enough for these mites to utilize their water vapours sorption capability and to restore a previously-suffered water deficit.

Investigation into the critical equilibrium humidity, active atmospheric water absorption and water content ofRhipicephalus evertsi mimeticus

The critical equilibrium humidity for fully engorged nymphs ofRhipicephalus evertsi mimeticus was shown to be between 91% and 93.5% r.h., and for adult male and female ticks to be between 82% and…

Diversity of Feather Mites (Acari: Astigmata) on Darwin's Finches

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.

Climate-Driven Variation in the Intensity of a Host-Symbiont Animal Interaction along a Broad Elevation Gradient

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.

The potential role of phoresy in the evolution of parasitism: radiolabelling (tritium) evidence from an astigmatid mite

Experimental evidence is presented that the heteromorphic deutonymph of an astigmatid mite (Hemisarcoptes cooremani) acquires materials directly from the haemolymph of its beetle host (Chilocorus cacti).

Darwin’s finches habitually anoint their feathers with leaves of the endemic tree Psidium galapageium during the non‐breeding season

Birds host a wide range of ectoparasites and have developed behavioural strategies to combat them, such as preening, dust bathing and water bathing. In addition, a wide range of avian taxa anoint…

The Effect of Selective Logging on the Community of Chewing lice and Feather mites Associated with Forests Birds in Sabah, Malaysia

Part I of this four-part series describes how the search for a permanent home for astronaut Tim Peake began and the efforts to find a permanent resting place for the remains of the American space agency, the USGS, ended in disappointment.

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.
