BEHAVIOURAL ADAPTATIONS TO MOISTURE AS AN ENVIRONMENTAL CONSTRAINT IN A NOCTURNAL BURROW-INHABITING KALAHARI DETRITIVORE PARASTIZOPUS ARMATICEPS PERINGUEY (COLEOPTERA: TENEBRIONIDAE)

Behavioural adaptations to moisture as an environmental constraint in a nocturnal burrow-inhabiting Kalahari detritivore Parastizopus armaticeps Peringuey (Coleoptera: Tenebrionidae)

The nocturnal desert detritivore Parastiz.opus armaticeps shows differences in surface activity patterns and burrow fidelity depending on surface humidity.After rain approximately half of the beetle population, independent of sex, is highly vagile and disperses over long distances.During drought, beetles are more sedentary Counter Stool Set and sho

The relationship between host lifespan and pathogen reservoir potential: an analysis in the system Arabidopsis thaliana--cucumber mosaic virus.

Identification of the determinants of pathogen reservoir potential is central to understand disease emergence.It has been proposed that host lifespan is one such determinant: short-lived hosts will invest less in costly defenses against pathogens, so that they will be more susceptible to infection, more competent as sources of infection and/or will

Reduction of lateral forces between the railway vehicle and the track in small-radius curves by means of active elements

This paper deals with a possibility of reduction of guiding forces magnitude in small-radius curves by means of active elements.These guiding forces characterize the lateral force interaction between the rail vehicle and the track and influence the wear Counter Stool Set of wheels and rails in curves.Their magnitudes are assessed in the framework o
