How plants respond to attack by the range of herbivores and pathogens that confront them in the field is the subject of considerable research by both molecular biologists and ecologists. However, in spite of the shared focus of these two bodies of research, there has been little integration between them. We consider the scope for such integration, and how(More)
Understanding the potential impact of ozone depletion on terrestrial ecosystems is constrained by lack of information on the effects of environmentally realistic UV-B doses on terrestrial organisms other than higher plants. Increasing UV-B may alter interactions between plants and consumers through direct effects on consumer organisms (herbivores,(More)
5-HT1B autoreceptors are involved in the control of extracellular 5-HT levels from both the terminal and cell body regions of serotonergic neurones. In this study we report on the effect of a selective and potent 5-HT1B receptor inverse agonist, SB-236057-A(More)
Age changes of foliage resource quality (water, nitrogen, fibre, phenolics and toughness) were studied in five species of conifer (Pinus sylvestris L.), Picea abies (L.) Karsten, Tsuga heterophylla (Rafinesque) Sargent (all Pinaceae), Chamaecyparis lawsonian (Murray) Parlatore and Thuja plicata D. Don (both Cupressaceae) over a 2-year period in an English(More)
Plants encounter numerous pests and pathogens in the natural environment. An appropriate response to attack by such organisms can lead to tolerance or resistance mechanisms that enable the plant to survive. Many studies concentrate on the signalling pathways that enable plants to recognize and respond to attack, and measure the downstream effect in either(More)
Many plant RNA isolation techniques aim to prevent contamination by means of secondary phenolics, carbohydrates, RNase, and other chemicals. However, when applied in our laboratory to the isolation of RNA fromRumex obtusifolius, these protocols failed to produce good quality RNA. A major problem was contamination of the RNA samples with the secondary(More)
Peter Price’s Insect Ecology is one of the oldest-running textbooks in this area, first appearing in 1975. I remember using this as an undergraduate in the early 1980s when there was little else available, especially with a comparable breadth of coverage. Insect Ecology went through a second edition in 1984, a third in 1997, and after 30 years of(More)
A 55-year-old man presents with a 10-cm condylomatous penoscrotal mass. Final pathology after surgical removal reveals a rare vegetative lesion with underlying herpes simplex virus infection. Along with neoplasia, infectious causes must remain in the differential diagnosis in the immunocompromised patient who presents with an atypical lesion.
The effect of infection by the rust fungus Uromyces rumicis and fertilization by different concentrations of nitrate or ammonium solutions on the concentrations of alcohol-soluble carbohydrates, fructans and starch in Rumex obtusifolius leaves was investigated. In leaves from healthy plants there was an increase in concentration of alcohol-soluble(More)
