    Notizen: Abstract The Arabian Gulf catfish Arius thallasinus excretes copious amounts of proteinaceous gel from epidermal cells when threatened or injured. As a means of investigating its biological role, this gel material has been examined to determine the nature of the secretion and its associated biological activities. Over 85% of the dry weight of the gel material is protein with small amounts of lipids, carbohydrates and nucleic acid components. Most of the protein exists as a high molecular weight aggregate of predominantly 13 500 molecular weight monomeric units. Several lytic enzyme activities are found in the gel secretion, one of which catalyzes lysis of red blood cells. Other factors induce clotting in citrate treated plasma and agglutination of red blood cells. The enzymic properties of the gel secretion resemble those of some animal venoms.

    Notizen: Abstract The Arabian Gulf catfish (Arius thalassinus, Rüppell) secrete a thick layer of proteinaceous material when threatened or injured. The chemical and pharmacological properties of this material indicate that it may promote the healing of wounds. These studies suggest that the abrupt secretion of mucous-like gel in response to a perceived hazard is an externally expressed defense response; the secretion may have a primary function in healing injury beyond the commonly postulated roles of deterring predators or facilitating escape.

    Notizen: Isothermal microcalorimetric analysis of cut fresh pineapple was used to examine metabolic events occurring in the fruit under different storage conditions. The results define conditions most suited for cut pineapple storage. The baseline heat production for pineapple tissue is quite low (0.2 μW per mg wet weight). During storage, heat producing metabolic reactions develop which cause spoilage of the fruit. The time course of heat production during storage is affected by changes in atmosphere and by chemical treatments. Effects of inhibitor and antibiotic additions indicate that most of the heat production associated with spoilage is related to the growth of microbial flora.

    Notizen: The relation between growth rate traits (height, basal diameter, stem volume and branch diameter) and two measures of respiration rate [metabolic heat rate (q) and CO2 production rate (Rco2)] and their ratio (q/Rco2) was examined on a collection of 192 different genotypes of coast redwoods [Sequoia sempervirens (D.Don) Endl.]. Branch diameter was not correlated with any of the respiratory measures, but the other three growth traits gave highly significant (P 〈 0.001) correlations with positive slopes. Combining the four growth traits and the three respiratory variables (q, RCo2 and q/Rco2) to give two canonical variates, one representing growth and one representing respiration, gives an even stronger linear correlation (r= 0–85). These data suggest that simultaneous assay of multiple respiratory measures on juvenile trees can be used to predict their longer-term growth rates.

    Notizen: The spatial distribution of a plant species is limited by the range of climatic conditions to which the species can adapt. Temperature is one of the most significant determinants of plant distribution, but except for the effects of lethal limits, little is known about physiological changes in responses to differences in environmental temperature. In this study, temperature coefficients of non-photosynthetic metabolism have been determined in the normal environmental temperature range for selected annual and perennial plants. Distinct differences were found in the temperature coefficient of metabolism of woody perennial plants from high latitudes and high elevations and closely related low-latitude and low-elevation plants. Low-latitude and low-elevation woody perennials have Arrhenius temperature coefficients for metabolism that are larger than those for congeneric high-latitude and high-elevation plants. The Arrhenius temperature coefficient is not rapidly adapted to new environments. A simple function was developed relating Arrhenius temperature coefficient to latitude and elevation for accessions of three, woody, perennial species complexes of plants collected from a wide geographic range but grown in common gardens. Within these taxa, plants that experience broader ranges of temperature during growth in their native habitat have smaller temperature coefficients. Temperature coefficients also varied with growth stage or season. No similar relationship was found for annuals and herbaceous perennials. For the plants tested, Arrhenius temperature coefficients are high during early spring growth, but shift to lower values later in the season. The shift in Arrhenius temperature coefficients occurs early in the season for southern and low-elevation plants and progressively later for plants from further north or higher elevation. The changes in Arrhenius temperature coefficients result largely from increases in plant metabolic rates at lower temperatures while little change occurs in the rates at higher temperatures. Altering the temperature dependence of the control of metabolic rate is apparently an important means of response to climate change.
