Auditory thalamic organization: Cellular slabs, dendritic arbors and tectothalamic axons underlying the frequency map. Neuroscience 2005; 136:927-43.

Abstract
A model of auditory thalamic organization is presented incorporating cellular laminae, oriented dendritic arbors and tectothalamic axons as a basis for the tonotopic map at this level of the central auditory system. The heart of this model is the laminar organization of neuronal somata in the ventral division of the medial geniculate body (MGV) of the rabbit, visible in routine Nissl stains. Microelectrode studies have demonstrated a step-wise ascending progression of best frequencies perpendicular to the cell layers. The dendritic arbors of MGV neurons are aligned parallel to the cellular laminae and dendritic tree width along the frequency axis corresponds closely with the frequency steps seen in microelectrode studies. In the laminated subdivision, tectothalamic axons terminate in the form of bands closely aligned with the laminae and dendritic arbors of thalamic relay neurons. The bands of tectothalamic axons extend in the anterior-posterior (A-P) plane forming a dorsal-ventral series of stacked frequency slabs. In the pars ovoidea region, the homologous spiraling of somata, dendritic fields and tectothalamic axons appear to represent a low-frequency area in this species. At least two types of tectothalamic terminals were found within the bands: large boutons frequently arranged in a glomerular pattern and smaller boutons arising from fine caliber axons. We propose that the rabbit is an ideal model to investigate the structural-functional basis of functional maps in the mammalian auditory forebrain.

Abstract
Information on the magnitude and variability of flow regimes at the river reach scale is a central component of most aspects of water resource and water quality management. However, many decisions are made within catchments for which there are no measured flow data. To meet this challenge, a suite of modelling techniques to assist in the estimation of natural and artificially influenced river-flows at ungauged sites has been developed. This paper summarises these models and how they are incorporated within the GIS framework of the Low Flows 2000 software package. The paper will also describe the implementation of Low Flows 2000 within England and Wales by the Environment Agency, and the use of the system in supporting the implementation of the Environment Agency's Catchment Abstraction Management Strategy. This strategy is focused on the delivery of sustainable abstraction licensing and will contribute to the implementation of the Water Framework Directive within England and Wales.

Abstract
The effects of different wavebands of UV radiation on photosynthesis and the expression and abundance of photosynthetic proteins in oilseed rape (Brassica napus L. cv. Rebel) were investigated. Plants were grown outdoors under natural radiation (52 degrees N, 0 degrees E) supplemented with six wavebands of UV radiation (0.4 Wm(-2)) between 313 nm and 356 nm. A control treatment was centred at 343 nm. Exposure to supplementary UV-A radiation (320-400 nm) had no significant effects, however UV-B radiation, centred at 313 nm, caused a marked reduction in photosynthesis. This decrease was related to a reduction in the initial carboxylation velocity of Rubisco which was further correlated with a large reduction in the expression and abundance of both large and small subunits of Rubisco. These results indicate a molecular mechanism behind UV-B induced reductions in photosynthesis per unit area in plants grown under field conditions.

Abstract
A polychromatic irradiation system for the outdoor exposure of plants or other samples to additional UV and longer-wavelength radiation has been constructed and tested. The system provides a range of wavebands in the ultraviolet-B radiation (280-315 nm) and ultraviolet-A radiation (315-400 nm) spectral regions, and the irradiance is fully adjustable. The performance of the lamp and filter system after over 4000 h of use is described; a brief description of filter degradation after over 30,000 h of use is also presented. Cellulose acetate filters were found to be adequate for some purposes in the UV waveband, but rigid plastic and glass-based filters were superior in terms of stability and the range of spectral combinations available. They also exhibited relatively small changes in transmittance with time. The system is also convenient for the measurement of differential polychromatic action spectra.

Abstract
The effects of supplementary ultraviolet-A (UV-A) and ultraviolet-B+A (UV-B+A) in the natural environment on the growth and morphology of various ecotypes of Arabidopsis thaliana were investigated. The ecotypes investigated were Columbia (Col-4), Landsberg erecta (Ler-0), Cvi-0, Wassilewskija, Enkheim-D, Aa-0 and Di-1. The mutant hy-4 was also used. Results varied with the radiation treatment, ecotype and parameter measured. Plants subjected to elevated UV-A were both insensitive (all parameters Cvi-0 and Col-4) and sensitive. When responses to UV-A occurred they were mostly inhibitory (all significant responses of Di-1 and Enkheim-D, most parameters of Wassilewskija, and some parameters of hy-4), however, promotive affects were observed for some parameters of Aa-0 and Ler-0. Supplementary UV-B+A inhibited all parameters of Di-1 and Enkheim-D and most parameters of Col-4, Ler-0 and hy-4, but Wassilewskija, Aa-0 and Cvi-0 were mostly insensitive. The magnitude of the UV-B+A response varied with ecotype (compare Di-1 with Ler-0). Some ecotypes were sensitive to UV-A but not UV-B+A (Aa-0), whereas others (Ler-0, Col-4) show the opposite sensitivities. A linear relationship is reported between the degree of UV-B+A inhibition of each ecotype and growth rate. The higher the growth rate the more susceptible the ecotype is to UV-B+A inhibition. This relationship holds for the majority of growth parameters measured.

Abstract
As part of an ongoing investigation into the effects of long-term UV-B radiation exposure on the growth and morphology of woody perennials, the gas exchange and photosynthesis of five common deciduous tree species were measured. All five tree species had been exposed to UV-B radiation for 5 years, in the field, at an enhancement level equivalent to an 18% ozone depletion. Measurements made during the fifth year of UV-B irradiation recorded reductions in light-saturated photosynthesis, transpiration and water use efficiencies. These changes were accompanied by marked reductions in individual leaf areas, stomatal density, stomatal conductance and carboxylation efficiency. There were no significant changes in the maximum variable fluorescence ratio, the quantum requirement of oxygen evolution, or light-saturated O(2) production. Analysis of the response of net carbon assimilation to changing intercellular CO(2) concentration (A/c(i) response) demonstrated no significant change in stomatal limitation. Reductions in photosynthesis were consistent with decreased carboxylation efficiency. Although all five tree species were similarly affected by UV-B radiation treatment, the magnitude of the responses was species-specific. These findings demonstrate the need for more long-term experimentation and also suggest that changes in water use efficiency may be a significant factor in plants' responses to UV-B radiation.

Abstract
Polychromatic ultraviolet (UV) action spectra for various growth responses of the dicotyledon Bellis perennis L. (daisy) and the grass Cynosurus cristatus L. (crested dog's-tail) have been measured. The plants were grown in the natural environment and ambient daylight was supplemented with five different UV irradiances centred at eight different wavelengths (313, 318, 320, 322, 339, 348, 356 and 377 nm). Destructive growth analysis was performed on B. perennis and C. cristatus after 300 and 122 days respectively. Dose response curves were created to construct action spectra for individual responses. Different spectral responses were observed in these two plant types. B. perennis exhibited a substantial action maximum at 313 nm for the inhibition of aerial, root and total dry weight; a similar action maximum at 313 nm for the inhibition of leaf expansion was observed. Longer wavelengths were relatively ineffective on these growth parameters, with the exception of a small but statistically significant (P < 0.05) response to 320 nm radiation. By contrast, C. cristatus showed negligible response to 313 nm radiation, for inhibition of aerial, root and total dry weight but substantial responses to longer wavelengths, especially at 339 and 348 nm. These action spectra add weight to suggestions in the literature that UV-A has a role to play in responses in this region of the spectrum. The possible implications of these observations are discussed.

Abstract
Some responses of various meadow species to enhanced UV-radiation of the natural daylight spectrum are described together with the experimental protocol employed. Growth responses to supplementary UV-B+A are mostly inhibitory when compared to the ambient daylight treatment for Bellis perennis, Cardamine pratensis, Cynosurus critatus and Ranunculus ficaria. However, the response of UV-A treatment compared to that of the UV-B+A varies in significance according to the species and parameter investigated. The pertinence of the ambient and UV-A treatment to data interpretation is discussed. Stomatal conductance of B. perennis was measured throughout the 24 h cycle. Although no significant difference could be found between the stomatal conductance of UV and ambient treated plants during the hours of daylight, at night it was found that the UV-B+A treated plants were unable to achieve the same degree of closure as the ambient treated plants. UV-damage and growth responses could alter the diversity of the meadow ecosystem and these effects could be exacerbated by water loss.

Abstract
The influence of far-red (FR; 700-800 nm) radiation on steady-state stomatal conductance and net photosynthesis in P. vulgaris has been studied. Whereas FR radiation alone was relatively ineffective, addition of FR to a background of white light (WL; predominantly 400-700 nm) resulted in increased stomatal conductance. Stomata exhibited a marked diurnal sensitivity to FR. The action maximum for enhancing stomatal conductance was near 714 nm. A combination of FR and infra-red (IR; >800 nm) enhanced net photosynthesis when added to a background of WL. When IR alone was added to WL, there was a net decrease in photosynthesis, indicating that it is the FR waveband which is responsible for the observed photosynthetic effects. Naturally occurring levels of FR radiation (235 μmol·m(-2)·s(-1)) in vegetation-canopy shade enhanced net photosynthetic CO2 gain by 28% when added to a background of 55 μmol·m(-2)·s(-1) WL.

Abstract
Stomatal diffusion resistance in primary leaves of Phaseolus vulgaris L. which had been grown in light:dark cycles followed a marked circadian rhythm when the plants were transferred to continuous darkness. Reentrainment of the rhythm required more than one inductive change in photoperiod. The phasing of the rhythm of dark stomatal opening was contolled primarily by the light-on (dawn) signal, whereas the rhythm of dark closure was related to the light-off (dusk) signal. The evidence points to a dual control of the circadian clock in which a product of photosynthesis plays a major role. No evidence for phytochrome involvement in the phasing of the rhythm was found. An influence of phytochrome on the amplitude of the stomatal rhythm was observed in which removal of phytochrome-far-red absorbing form caused rapid damping.

Evidence for phytochrome involvement in light-mediated stomatal movement in Phaseolus vulgaris L. PLANTA 1985; 166:348-53.

Abstract
Observations made with primary leaves of Phaseolus vulgaris L. demonstrated that phytochrome modulates light-induced stomatal movement. Removal of the far-red-absorbing form of the pigment (Pfr) with far-red (FR) radiation decreased the time required by the stomata to reach maximal opening following a dark-to-light transition; this effect of FR was fully reversible with red. Removal of Pfr with FR also decreased the time required to reach maximal closure following a light-to-dark transition, and the rate of closure was dependent on the final irradiation treatment before darkness. No evidence was found for phytochrome involvement in determining stomatal aperture under constant conditions of either darkness of light.

Abstract
The spectral control of hypocotyl elongation in light-grown Chenopodium rubrum L. seedlings has been studied. The results showed that although the seedlings responded to changes in the quantity of combined red and far-red radiation, they were also very sensitive to changes in the quantity of blue radiation reaching the plant. Altering the proportion of red: far-red radiation in broad waveband white light caused marked differences in hypocotyl extension. Comparison of the responses of green and chlorophyll-free seedlings indicated no qualitative difference in the response to any of the light sources used, although photosynthetically incompetent plants were more sensitive to all wavelengths. Blue light was found to act primarily of a photoreceptor which is different from phytochrome. It is concluded that hypocotyl extension rate in vegetation shade is photoregulated by the quantity of blue light and the proportion of red: far-red radiation. In neutral shade, such as that caused by stones or overlying soil, hypocotyl extension appears to be regulated primarily by the quantity of light in the blue waveband and secondarily by the quantity of light in the red and far-red wavebands.

Action spectra for changes in the "high irradiance reaction" in hypocotyls of Sinapis alba L. PLANTA 1981; 153:267-272.

Abstract
Detailed action spectra are presented for the inhibition of hypocotyl extension in dark-grown Sinapis alba L. seedlings by continuous (24 h) narrow waveband monochromatic light between 336 nm and 783 nm. The results show four distinct wavebands of major inhibitory action; these are centred in the ultra-violet (λmax=367 nm), blue (λmax=446 nm), red (λmax=653 nm) and far-red (λmax=712 nm) wavebands. Previous irradiation of the plants with red light (which also decreases Ptot) causes decreased inhibitory action by all wavelengths except those responsible for the red light inhibitory response. Pre-irradiation did not alter the wavelength of the action maxima. It is concluded that ultra-violet and blue light act mainly on a photoreceptor which is different from phytochrome.

Abstract
Anthocyanin formation in 36h dark grown Sinapis alba L. seedlings and inhibition of hypocotyl elongation in 36h and 54h dark grown and 54h and 7 day light grown seedlings in response to continuous red light could be substituted for by hourly 5 min light pulses where the total fluence over the irradiation period is the same. These pulses are partially (36h) or almost totally (54h and 7 day) reversible by subsequent far-red (RG 9) light pulses. In contrast to 654 nm light, hourly light pulses with 552 nm, 449 nm and 715 nm can at best only partially substitute for continuous irradiation. These data are discussed with respect to the commonly used models for the phytochrome high irradiance response.

Abstract
Relative quantum responsivity curves for inhibition of hypocotyl elongation in Sinapis alba L. seedlings previously grown in white light confirm that a marked "end of day" inhibition response can be induced by a monochromatic light treatment (30 min) at the end of the light period. In dark grown seedlings, however, no growth inhibition can be induced by a 30 min monochromatic light treatment. A prerequisite for an induction response appears to be a pretreatment with continuous light. Far red light is most effective with blue and red light showing a lesser effectiveness. The light pretreatment also shows a marked fluence rate dependency with respect to its ability to allow an induction response to manifest itself. The pretreatment required shows all the characteristics of a classical "HIR" response. The appearance of the effect in plants treated with the herbicide SAN 9789 seems to exclude chlorophyll as being the photoreceptor.

Abstract
Action spectra for the inhibition by continuous (24-hour) irradiation of hypocotyl growth in 54-hour-old Sinapis alba L. seedlings were measured using seedlings which had had four different pretreatments. These seedlings were either (a) dark-grown with a high total phytochrome level, (b) dark-grown with a low total phytochrome level, (c) light-grown with chlorophyll, or (d) light-grown with no chlorophyll [treated with 4-chloro-5-(methylamino)-2-(alpha,alpha,alpha-trifluoro-m-tolyl)-3(2H) -pyridazinone (San 9789)].The resulting action spectra show that the blue, red, and far-red (716 nm) wavebands are most inhibitory for dark-grown plants with high phytochrome content, whereas hypocotyl growth in dark-grown plants with a low phytochrome content are only slightly inhibited by blue and far-red radiation. In light-grown plants, the effectiveness of blue and far-red light almost disappears. The position of red light effectiveness in chlorophyll-containing plants is shifted to lower wavelengths compared with those containing no chlorophyll.
