The parameter Q10 is commonly used to express the relationship between soil CO2 efflux and soil temperature. One advantage of this parameter is its application in a model expression of respiration losses of different ecosystems. Correct specification of Q10 in these models is indispensable. Soil surface CO2 efflux and soil temperature at different depths(More)
A new radio-telemetric technique for neuroethological investigation of the natural behaviour of insects is presented. The 2-channel miniature transmitter device allows the transmission of electromyograms of 2 muscles during free flight of a locust. The mass of this transmitter and power supply is 0.55 g and can be carried by a mature female without marked(More)
Study of the insect neuromuscular system appears very promising as a means of explaining behaviour in terms of cellular operation. The relatively small number of neurons, the ganglionic nature of the nervous system, the simplicity of the neuromuscular arrangement, and the repetitiveness of behavioural sequences all lend themselves to a solution of this(More)
With a data set of Eurasian forest litter fall based on 471 stands, annual litterfall was estimated to be 6.53 Pg dm·a−1 (1 Pg=1015 g;dm, dry matter) in Eurasian forests, of which more than half occurred in tropical and subtropical forests, and a third in the boreal area. With litterfall, around 2.94 Pg C per year is transferred from the forest vegetation(More)
The Ti1 pioneer neurons arise at the distal tip of the metathoracic leg in the grasshopper embryo, and are the first neurons in the limb bud to extend axons to the central nervous system (C. M. Bate (1976) Nature (London) 260, 54-56; H. Keshishian (1980) Dev. Biol. 80, 388-397). By providing a neural pathway along which growth cones of later arising neurons(More)
Scientists have long been interested in recording data from freely moving animals. For larger animals, several telemetric techniques are available not only for following the movement of unrestrained animals in the wild (White and Garrott, 1990) but also for transmitting measures of heartbeat, body temperature, wingbeat, respiration, etc. (e.g. Lord et al.(More)
Environmental research infrastructures (RIs) support their respective research communities by integrating large-scale sensor/observation networks with data curation services, analytical tools and common operational policies. These RIs are developed as pillars of intra-and interdisciplinary research, however comprehension of the complex, pathologically(More)
