When single leaves attached at a given node were allowed to carry on photosynthesis in 14CO2 for 30 min, younger plants showed a higher proportion of upward translocation than did older plants. Downward translocation of 14C-photosynthate was stimulated by ATP pre-treatment of the translocating leaf, while upward translocation was not affected by ATP. A similar phenomenon was observed in the tra...

The low cost of electricity in some areas facilitates the adoption high-temperature electrolysis plants for large-scale storage electricity. Supercritical water gasification (SCWG) is a promising method syngas production from wet biomass. Additionally, it potential source steam electrochemical plants. However, commercialisation standalone SCWG systems hindered by efficiency and high operating c...

Widespread destruction of tallgrass prairies in the midwestern United States has fragmented plant communities with the result that populations of endemic animal species have become geographically isolated from one another. The goal of the research summarized here was to evaluate the potential for conserving endemic prairie species of herbivorous insects by managing their host plants. Our study...

Field experiments were performed to examine the effect of adult diet on calling activity, female attraction, and mating success in male Mediterranean fruit flies, Ceratitis capitata (Wiedemann). In all tests, comparisons were drawn between males fed sugar only (“proteindeprived” males) and males fed a protein-sugar mixture (“protein-fed” males). In tests of long-distance attraction, aggregation...

Effects of four host plants, tobacco, Chinese cabbage, cowpea and sweet potato, on larval and pupal development and survival, and longevity and fecundity of adults of Spodoptera litura (F) (Lepidoptera: Noctuidae), were studied under laboratory conditions (26 degrees C, 60-80% RH), as was the utilization of the four host plants and adaptation on tobacco. All of the biological parameters include...

Recent studies have shown that entomopathogenic fungi, as endophytes, can beneficial effects on plants, protecting them from defoliating insects. The potential of endophytic association by fungi with the peanut crop has been little explored. In our study, we conducted experiments inoculation seeds through a soil drench method nine strains/species genera Metarhizium , Beauveria and Cordyceps sub...

Avian song learning is an important model system for understanding vocal learning in humans and other animals. Laboratory studies indicate that social interactions are critical for song learning, but field observations show that territorial males are aggressive to intruders, raising the question of whether young birds are tolerated, much less tutored in the wild. We examined how adult song spar...

We describe a basic Geo-coding service encompassing a geo-parsing tool and integrated digital gazetteer service. The development of a geo-parser comes from the need to explicitly georeference large resource collections such as the Statistical Accounts of Scotland which currently only contain implicit georeferences in the form of placennames thus making such collections inherently geographically...
