C. A. 35, 8017.8. Amino-acid analyses were made of hydrolyzates of the total proteins extd. by 90% formic acid from 1 blue-green alga, Gloeotrichia (I); 5 brown algae, Macrocystis, Lessioniopsis, Fucus (II), Cystoseira (III), Egregria (IV) and 2 green algae, Caulerpa (V) and Codium. All the brown algae contain lysine but II, III and IV lack arginine. I lacks cystine and V lacks lysine. Further confirmation of the apparent generality that brown, but not green marine algae, contain mannitol was obtained. [on SciFinder (R)] Notes: CAN 36:20820 11D

Year: 1941 Title: The Developmental History of Cedar Creek Bog, Minnesota Journal: American Midland Naturalist Volume: 25 Issue: 1 Pages: 101-112 Date: Jan. Abstract: The Cedar Creek Bog was formed as an ice-block lake in pitted sand-outwash topography, following recession of Keewatin ice during the Late Wisconsin glaciation. The lake is at present in a late stage of senescence, water occupying less than 1/10 of its original depth and area. Marginal succession is proceeding with great rapidity; the sedge mat vegetation showed radial invasion of 0.95 meter in 5 years. Nine years of observations, supported by photographic evidence, indicates that precipitation has been an important factor in the dominance of Decodon over Typha as the foremost invader of the encircling sedge mat. An extensive forest of Thuja occidentalis, encompassing a girdle of Larix laricina, covers the peripheral area of the lake basin. Observations on the sediments of the Cedar Bog basin indicate that marl is the most extensive deposit, comprising at least 50% of the total. The mart is underlain in the deepest areas by a thin layer of fine-detritus gyttja, and is interrupted in its middle region by a second thin, sharply marked stratum of gyttja. The marl ceases abruptly above a sediment depth of 4 meters. A silty deposit tentatively termed sapropsammite occurs in the littoral area of the lake basin at sediment depths of 1 to 3 meters. The present lake is underlain by a deposit described as avja-gyttja, which merges peripherally into a blackish type designated as Decodon-sapropel. Beneath and peripheral to the sedges mat occurs a thick layer of sedge peat, overlain beneath the bog forest by a thin stratum of forest peat. Notes: FLA 00030031

Year: 1941 Title: Seasonal Food-Cycle Dynamics in a Senescent Lake Journal: American Midland Naturalist Volume: 26 Issue: 3 Pages: 636-673 Date: Nov. Abstract: 1. Cedar Bog Lake, which has been the subject of a four-year study in dynamic ecology, represents a late stage of eutrophic senescence. 2. A generalized diagram of food-cycle relationships is presented: the autotrophic plants, free-floating and attached, are the producers of organic substance; numerous animal groups play intricate, inter-related roles as primary, secondary, tertiary, etc., consumers of this organic substance; heterotrophic bacteria act as decomposers of organic substance and, from another point of view, as regenerators of essential plant nutrients, which again contribute to the synthesis of organic substance. 3. The biotic inter-relationships of the various consumer groups, particularly the browsers, benthic predators and swimming predators, are discussed in some detail. 4. The quantitative seasonal distribution of food groups showed remarkable variation from year to year. These annual variations seemed to be correlated at least in part with marked fluctuations in water level and in chemical composition of the water. Prolonged winter anaerobiosis often completely destroyed the swimming predators and decimated the numbers in other food groups. 5. Climatic variations, resulting in water level changes, winter anaerobiosis, etc., played an important role in the annual productivity of this senescent lake. 6. Limited predator-prey dynamics were suggested in the population ratio of zooplankters to nannoplankters and of Chaoborus larvae to net plankters (Fig. 5). Plankton predators were relatively the most variable of the food groups with respect to annual production, while nannoplankters were relatively the least variable. 7. The mean annual ratios of producers to primary consumers to secondary consumers (including the small swimming predators found in the lake) were: 70.3:7.0:1.3 cal/cm$^2$. Annual variation was relatively greatest for the secondary consumers and least for the producers. 8. The relative annual production of the food groups, as might be anticipated on theoretical grounds, indicates an efficiency of food conversion much lower than the probable physiological efficiency ratios of the species. Only occasionally did the factor of food supply appear to limit the production of a food group. Notes: FLA 00030031

Year: 1937 Title: An Ecological and Taxonomic Investigation of the Littoral Algal Flora of Lake Windermere Journal: The Journal of Ecology Volume: 25 Issue: 2 Pages: 496-568 Date: Aug. Abstract: The littoral algae of Lake Windermere have been studied from a taxonomic and ecological point of view. Systematic notes are added on some of the species. The main results obtained may be summarized under three heads: (A) Ecological factors. (B) Periodicity. (C) Origin of plankton algae. A. Ecological factors The distribution of the littoral algae has been found to depend on depth of water, light intensity, factors associated with the habitat viz. (a) substratum, (b) proportions of organic matter and dissolved substances, and possibly temperature. The effects of these factors may be summarized as follows: (1) Substratum. (i) Stones. Certain blue-green algae, e.g. Dichothrix orsiniana, Nostoc verrucosum, are found only on stones; these form communities in the spray-zone, at 0-0.5 m., and at 1-3 m. Other species characteristic of stones are not restricted to them; these include such blue-green forms as Schizothrix funalis, a few species of diatoms, and among green algae mainly Ulothrix, Stigeoclonium and Spirogyra. (ii) Plants. The growth comprises numerous green and blue-green forms, as well as the bulk of the diatoms, including those found on stones, with the exception of Denticula tenuis; the diatoms listed under (iii) are also lacking here. (iii) Mud and associated debris. There is a special mud community composed of diatoms, e.g. species of Pinnularia and Nitzschia, Microcoleus delicatulus, occasionally with Cladophora Sauteri. (iv) Glass slides. These were colonized only by the algae of the macrophyte belt, chiefly by the diatoms and Lyngbya perelegans. Certain diatoms (Cocconeis, Eunotia veneris) appeared especially on slides placed on the bottom. (2) Depth of water. (i) Shallow water communities found on stones, whose total depth range is from 0 to 3 m. (ii) Communities of the macrophyte belt, extending according to the type of shore either from 0 to 3 m., or from 1 (or more) to 6 (rarely 6.5) m. Three of the diatoms were found in small numbers on glass slides at 15 m. (iii) The mud community, found also in shallow water, extends to a greater depth than any other, diatoms reaching 12 m. and Microcoleus 16 m. (3) Nature of habitat. (i) One can distinguish communities characteristic of stony and primitive "inorganic" shores (including Ulothrix zonata, Cymbella ventricosa etc.), of swampy evolved "organic" shores (including Batrachospermum moniliforme, Eunotia lunaris etc.), and of the mouths and lower parts of streams (including Stigeoclonium amoenum, Ceratoneis arcus etc.). These overlap to some extent. (ii) The proportions of certain dissolved substances in these different habitats have been to some extent investigated. They depend in part on the presence or absence of organic deposits. Apart from its probably considerable direct influence on the distribution of the algal species, organic matter is capable of ultimate oxidation with the production of nitrates. This process is favourably affected by disturbance of the water and hence by the degree of exposure of the habitat. The algal communities are found to be related to these differing conditions. (4) Depth of water and habitat jointly. (i) The depth at which algal communities associated with organic deposits are found depends on the depths at which these deposits occur, for example at 0-3 m. on "organic" shores and at approximately 3-6 m. on "inorganic" shores. (ii) There are differences in the depth distribution of the algae developing on slides suspended at different levels near the two kinds of shores. (5) Light. (i) The diatoms whose distribution has been investigated occur at shallower levels in winter than at other times, probably owing to the lower intensity of the light in winter. These diatoms frequently show a marked decrease in numbers towards the surface. This does not apply to other classes of algae, which have not been found on slides below 7 m., although diatoms have been found in small numbers at 15 m. (ii) Examination of growth on slides suspended at some distance from the shore shows that the influence of the shore habitat ceases to be dist nguishable at 4.5 m. On the natural substrata it is still observed at 6 m. The latter is also true of the macrophytic vegetation. This suggests that light cannot be a limiting factor in the upper layers of the water, although it may become limiting at 4.5 m. on suspended slides and at 6 m. on the bottom nearer the shore. (6) Temperature. Estimations of the dry weight of the total growth on slides suggest that temperature may control the amount of production. B. Periodicity Some species of algae have a well-marked periodicity, while in others it is only slightly marked or absent. The periodical development of the different algal classes in the littoral zone is in many respects similar to that which has been established for the plankton algae, but the phenomena are less pronounced; thus certain green algae attain a maximum in winter although the bulk do so in summer, while some of the diatoms show a minimum in summer and a secondary autumn maximum. The phenomena of periodicity have been studied in relation to depth and habitat. (a) Depth. In general the algae attain their greatest depth range at the time of their maximum, although there are exceptions; thus diatoms go deepest in spring, green algae in summer, while blue-green algae show no change or are found in shallow as well as deep water in summer. On the natural substrata however, Achnanthes and Cocconeis are relatively most frequent in the deeper water in December. (b) Habitat. The periodicity of certain species (e.g. Ulothrix zonata, Gomphonema olivaceum) is to some extent modified by the habitat in which they grow. C. Origin of plankton algae Observations on the plankton algae found in the littoral show that a littoral origin is possible for most of them, but no light is thrown on the origin of some important forms. The "organic" type of shore is most prolific in plankton forms. Notes: FLA 00220477

W. Year: 1935 Title: A study of ligneous substances in lacustrine materials Journal: Trans. Wisconsin Acad. Sci. Volume: 29 Pages: 389-402 Accession Number: AN 1936:26329 Keywords: Photosynthesis (by algae at different depths); Nannoplankton; Plankton (ligneous substances in); Muds (ligneous substances in lake) Abstract: The sulfuric acid method of Sherrard and Harris (C. A. 26, 1116) for the isolation of lignin from sawdust was applied with a reasonable degree of success to the analysis of 7 lake muds, 4 net plankton, 3 nannoplankton and 4 miscellaneous lacustrine types. Because of the relatively small number of samples examined, it is not deemed likely that the methoxyl content is an index of the amount of lignin present. The range of the lacustrine lignin content of the first three types was found to be, in the order named, 4.57 to 29.67%, 8.24 to 14.51% and 3.05 to 7.75%; that of Lobelia 10.13%, of Gloeotrichia 13.58%; of Isoetes 20.09%; of moss 19.37%. It constituted 30 to 40% of the total organic matter of the lake muds, 18% of the net plankton and 10 to 20% of the nannoplankton. Data and conclusions are tentatively submitted pending the examination of a greater variety of samples and the development of a more satisfactory technic. [on SciFinder (R)] Notes: CAN 30:26329 11D

Year: 1933 Title: A Classification of the Algae Based on Evolutionary Development, with Special Reference to Pigmentation Journal: Botanical Gazette Volume: 95 Issue: 1 Pages: 59-77 Date: Sep. Abstract: Inasmuch as the newer technique in spectral analysis and microchemistry has not yet been extensively applied to studies of pigments and food reserves in the various algal groups, one hesitates to make categorical statements regarding these matters at the present time. While a great amount of work has been done in the past, it has been carried on for the most part by individuals interested in but a small group of algae, or in but a limited phase of the subject. There is need for comparative chemical and physiological work embracing the pigments and products of assimilation in all of the classes of algae, as well as in the higher plants. In the absence of precise knowledge it may be stated that, in the passing from one algal group to the next (plate I), with every change in the pigment content of the chromatophore there apparently has been a corresponding change in the "metabolic level" of the whole organism. Possibly this change in the chromatophore-morphological perhaps, physiological certainly-has directly or indirectly influenced the type of reserve food products that the organism is able to synthesize.
