Black locust (Robinia pseudoacacia L.) is an easy to raise, fast growing, medium-sized deciduous tree species highly tolerant to harsh eco-conditions, i.e., drought and harsh winters, and it is widely adaptable to sandy, loamy, and marshy soils. The basis for this adaptability remains to be investigated at the transcriptomic level using real-time quantitative PCR (qPCR). Selection of a reliable...

Native tree species are frequently unable to effectively grow in non-native cultivation scenarios. In the Loess Plateau, China, it is difficult find native oak (Quercus liaotungensis) seedlings black locust forests. Black an arbuscular mycorrhizal (AM) tree, but ectomycorrhizal (ECM) tree. Plants highly depend on their symbiotic fungi take up water, nitrogen (N) and other nutrients. We hypothes...

The aim of this research is to measure the energy consumption and compare cutting performance three types battery-powered chainsaws (Stihl MSA 200, Stihl 220, 300). Tested were powered by two different battery packs AP 300 S 500 S) with capacity output current when wooden beams, European beech (Fagus sylvatica L.) black locust (Robinia pseudoacacia densities moisture content. Energy was measure...

Current paradigms generally assume that increased plant nitrogen (N) should enhance herbivore performance by relieving protein limitation, increasing herbivorous insect populations. We show, in contrast to this scenario, that host plant N enrichment and high-protein artificial diets decreased the size and viability of Oedaleus asiaticus, a dominant locust of north Asian grasslands. This locust ...

Swarming and the expression of phase polyphenism are defining characteristics of locust species. Increases in local population density mediate morphological, physiological and behavioural changes within individuals, which correlate with mass marching of juveniles in migratory bands and flying swarms of adults. The Australian plague locust (Chortoicetes terminifera) regularly forms migratory ban...

Wings and legs of the gregarious desert locust, Schistocerca gregaria have been shown to be release sites of phenylacetonitrile (PAN), the major adult male-produced pheromone. However, there is limited information on the distribution of PAN within the locust. Here we show, using gas chromatography-mass spectrometry (GC-MS), that PAN occurs in nearly all body parts of both adult males and female...

1. scylloInositol has been identified as a component of locust haemolymph, where it occurs in concentrations of 0.2-0.4mg./ml. 2. A simple method for the identification of scylloinositol is described. This has been used to demonstrate the presence of scylloinositol in five other insect species. 3. Locust phospholipids contain myoinositol but no scylloinositol. 4. Radioactivity from [(14)C]gluco...

Individual neurons in several sensory systems receive synaptic inputs organized according to subcellular topographic maps, yet the fine structure of this topographic organization and its relation to dendritic morphology have not been studied in detail. Subcellular topography is expected to play a role in dendritic integration, particularly when dendrites are extended and active. The lobula gian...
