    Description / Table of Contents: The analysis of stable isotope ratios represents one of the most exciting new technical advances in environmental sciences. In this book, leading experts offer the first survey of applications of stable isotope analysis to ecological research. Central topics are plant physiology studies, food webs and animal metabolism, bio-geochemical fluxes. Extensive coverage is given to natural isotopes of carbon, hydrogen, oxygen, nitrogen, sulfur, and strontium in both terrestrial and marine ecosystems. Ecologists of diverse research interests, as well as agronomists, anthropologists, and geochemists, will value this overview for its wealth of information on theoretical background, experimental approaches, and technical design of studies utilizing stable isotope ratios.

    Notes: Abstract A portable system for the rapid measurement of photosynthetic rates in the field is described and evaluated. The measurement of photosynthesis is based on extraction of volumes of air from a closed system cuvette containing a leaf over a set time interval. CO2 content of the gas volumes is determined with an infrared gas analyser, and photosynthetic rate is calculated from the cuvette CO2 concentration depletion rate. The magnitudes of sources of error with this system were analysed and methods of reducing the errors discussed. Representative examples of data obtainable with this technique are presented.From the inlet and outlet ports of a cuvette for measurements of Sorghum bicolor dark respiration rates in the laboratory. We have modified their technique and report the utility of the CO2 depletion technique for measurements of photosynthesis on plants in the field, far from laboratory facilities. The technique is reliable and easy to operate in the field. A description of the technique, as well as an analysis of the sources of error and examples of the data which can be obtained with it are presented.

    Notes: Abstract. A comparison between two sympatric winter desert annuals, Camissonia claviformis and Malvastrum rotundi folium showed that both gained similar amounts of carbon during a spring day, although by very different means. Camissonia has horizontally fixed leaves which have a very high photosynthetic capacity. The temperature optimum of photosynthesis for this species is near 20°C. Malvastrum has leaves with a lower photosynthetic capacity and a photosynthetic temperature optimum near 30°C. Leaves of the latter species remain normal to the sun throughout the course of the day. The tracking response and high temperature optimum for photosynthesis of Malvastrum result in a high daily carbon gain and also a high water-use efficiency.

    Notes: Abstract. Gas exchange responses of intact leaves of Lactuca serriola serriola and L. serriola integrifolia were examined. The light, temperature and intercellular CO2 dependence of photosynthesis of these two forms of L. serriola were indistinguishable. Dependence of photosynthesis on leaf temperature differed only slightly between plants grown at approximately 10/3°C and those grown at 33/25°C with the thermal optimum shifting 4°C. Transpiration was shown to increase exponentially with leaf temperature. The gas exchange characteristics of L. serriola are discussed in relation to water relations, carbon gain and compass leaf orientation under field conditions.

    Notes: Abstract Leaf shapes and leaf orientation of Lactuca serriola serriola and serriola integrifolia were studied. Leaf shapes in L. serriola serriola differed greatly from those of L.serriola integrifolia, but leaf surface areas were similar. In exposed habitats, leaf orientation of cauline leaves of both forms was non-random, with leaves almost vertical and tending to orient with their lamina normal to the east and west. In the shade, cauline leaves oriented randomly. An experiment demonstrated that the orientation of leaves did not change significantly once they were fully expanded. The leaf orientation in L. serriola affected the diurnal distribution of solar irradiance intercepted by a leaf. Peak solar radiation fluxes are incident on the rosette leaves at midday, but on the cauline leaves the peak solar radiation flux occurs early in the morning and again late in the afternoon. The significance of this unusual leaf orientation is discussed in relation to water loss and carbon gain.

    Notes: Abstract. In this review we relate the physiological significance of C4 photosynthesis to plant performance in nature. We begin with an examination of the physiological consequences of the C4 pathway on photosynthesis, then discuss the ecophysiological performance of C4 plants in contrasting environments. We then compare the performance of C3 and C4 plants when they occur together in similar habitats, and finally discuss the distribution of C4 photosynthesis with respect to the physical environment, phylogeny, and life form.

    Notes: Photosynthetic gas exchange and the stable isotopic composition of foliage water were measured for a xylem tapping mistletoe, Phoradendron juniperinum, and its host tree, Juniperus osteosperma, growing in southern Utah. The observed isotopic composition of water extracted from foliage was compared to predictions of the Craig-Gordon model of isotopic enrichment at evaporative sites within leaves. Assimilation rates of juniper were higher and stomatal conductance was lower than the values observed for the mistletoe. This resulted in lower intercellular/ ambient CO2 values in the juniper tree relative to its mistletoe parasite. For mistletoe, the observed foliage water hydrogen and oxygen isotopic enrichment was less than that predicted by the model. In juniper, foliage water hydrogen isotopic enrichment was also lower than that predicted by the evaporative enrichment model. In contrast, the oxygen isotopic enrichment in juniper foliage water was slightly greater than that predicted for the evaporative sites within leaves. Hydrogen isotopic enrichment in mistletoe foliage shows systematic variation with stem segment, being highest near the tips of the youngest stems and decreasing toward the base of the mistletoe, where isotopic composition is close to that of stem water in the host tree. In a correlated pattern, mid-day stomatal conductance declined abruptly in mistletoe foliage of increasing age.
