A Century of Great Lakes Research at the University of Michigan

The University of Michigan has had a long and productive history of promoting, enhancing, and facilitating research on the Laurentian Great Lakes. This interest in Great Lakes research was evident before the turn of the century under the leadership of Prof. Jacob E. Reighard. Early research was primarily concerned with fish and fisheries. The emphasis on fisheries started to shift to basic limnological research after the 1920s when Prof. Paul S. Welch started a limnology course and wrote his book Limnology. His student, Prof. David C. Chandler, returned to the University in 1953 to chair the Council of the Great Lakes Research Institute, and subsequently became the Director of the Great Lakes Research Division in 1960. The emphasis was and has been on basic and applied research involving a broad spectrum of disciplines. The published contributions include biology, chemistry, geology, meteorology, paleolimnology, physical limnology, pollution, radiolimnology, and integrated studies. Among the University's many contributions to furthering Great Lakes research was the origination of the Conferences on Great Lakes Research, started in 1953. Publications of the Proceedings of these conferences provided a valuable reference to research in the 1950s and 1960s. These conferences led to the formation of the International Association for Great Lakes Research and subsequently the Journal of Great Lakes Research. The University acquired several research vessels. The earliest large vessel acquired was the Inland Seas (1960) which was replaced by the Laurentian in 1974. A research submersible was brought into Lake Michigan for evaluation by the Great Lakes Research Division in 1966. At about this time Michigan Sea Grant Program was started in 1969 and the Coastal Zone Laboratory in the 1970s. More recently the Cooperative Institute for Limnology and Ecosystem Research was created in 1989 as a partnership among the University, Michigan State University, and the Great Lakes Environmental Research Laboratory of the National Oceanic and Atmospheric Administration. Much of the Great Lakes research activity at the University was realigned into several colleges and schools in the late 1980s. Great Lakes research at the University has passed through a number of reorganizations, and now exists as the Aquatic Research Programs of the University of Michigan Biological Station.

TAXONOMY AND SYSTEMATIC POSITION OF THEGOMPHONEIS QUADRIPUNCTATASPECIES COMPLEX

Contribution Number 000 of the Great Lakes Research Division Light microscopical observations were made on material from Lake Baikal containing Gomphoneis quadripunctata (Ostr.) Dawson ex Ross & Sims. The material had originally been used by Skvortzow to describe many subspecific taxa of this species. The many forms present all have multiple stigmoids positioned around the central area, septa at both poles, and undifferentiated apical pore fields. From the large number of taxa identified by Skvortzow, three species are recognized: G. hastata (Wisl.) Kociolek & Stoermer, comb, nov., G. tumida (Skv. in Skv. & Meyer) Kociolek & Stoermer, comb, nov., and G. quadripunctata. Species were segregated by differences in initial valve length and corresponding variation in valve shape and morphology. Of the three species recognized, G. hastata and G. tumida possess longitudinal lines in girdle view, while in G. quadripunctata such lines are absent. Relationships of these three species to G. olivaceoides (Hust.) Carte...

Estimation of Trace Metal Storage in Lake St. Clair Post-Settlement Sediments Using Composite Samples

Sediment cores were collected from 36 stations in Lake St. Clair during 1985 by divers. Usually within hours of collection, replicate cores were extruded and sectioned into 1-to 2-cm intervals. One replicate was stored by Canada Centre for Inland Waters personnel for organic contaminant, mercury, and major element analyses. The other replicate was stored by Great Lakes Research Division and Great Lakes Environmental Research Laboratory personnel for Cs-137, Pb-210, grain size, total carbon, and trace metal analyses. In order to estimate the mass of trace metals stored in the lake sediments, equal mass sections of each core were composited. These and individual sections of each core were analyzed and the total mass and anthropogenic mass of each metal in culturally impacted sediments were calculated. Estimated total and anthropogenic masses (metric tons) are: bismuth, 27 and 13; cadmium, 690 and 440; chromium, 5,100 and 1,800; copper, 3,000 and 1,500; nickel, 4,000 and 1,300; lead, 3,200 and 1,500; antimony, 25 and 13; and zinc, 11,000 and 3,300.

Observations on North American Gomphoneis (Bacillariophyceae). II. Descriptions and Ultrastructure of Two New Species

Two new species of the diatom genus Gomphoneis are described from Oregon (U.S.A.). Light and scanning electron microscopic observations of C. trullata n. sp. show that this diatom has striae with two rows of indistinct, slit-like puncta and an axial plate located circa 1/2-2/ the way between the axial area and the valve margin. As in other species of Gomphoneis, the axial plate is responsible for the image of longitudinal lines characteristic of the genus. Gomphoneis trullata is distinguished from previously described species by its distinctively shaped valves, which are widest between the central area and the footpole, and by the position of the longitudinal lines. The second species, G. linearis n. sp., is a rare form known only from the Metolius River. It is distinguished by its linear valve outline, submarginal longitudinal lines, and distinct doubly-punctate striae. The diatom genus Gomphoneis Cleve (exclusive of forms recently transferred from Gomphonema C.A.Ag. by Carter & Bailey-Watts, 1981; Dawson, 1974; and Lange-Bertalot, 1978) is relatively small, with but 11 taxa represented in the United States flora (Lohman, 1964; Patrick, 1975; Reimer, 1982; Schmidt, 1899). The genus also is restricted in distribution, with most previously described taxa being from Lake Baikal, U.S.S.R. (Skvortzow & Meyer, 1928), the Pacific Northwest, U.S.A. (Ehrenberg, 1854; Grunow, 1880; Schmidt, 1899), and the Great Lakes (Ehrenberg, 1854; Grunow, 1878). Other distributional reports include New Zealand (Foged, 1979; Wood, 1961), Australia (Wood, 1961), Great Smoky Mountains (Kociolek, 1982), Iowa (Reimer, 1982; Stoermer, 1964), France (Brun & Heribaud, 1893) and Chile (Rivera & Valdebenito, 1979). Although investigators have questioned the validity of the genus (see Lange-Bertalot, 1980), recent studies on Gomphoneis mammilla (Ehrenb.) Cl. (Kociolek & Rosen, 1984) support the separation of Gomphoneis from the closely allied genus Gomphonema. Comphoneis differs from Gomphonema by having a combination of (usually) double rows of puncta in the striae and longitudinal lines on either side of the axial area. The image of longitudinal lines has been shown to be produced by the edges of an expanded internal axial plate that underlies a portion of the striae (Kociolek & Rosen, 1984). 1 Contribution no. 439 of the Great Lakes Research Division. 2 We are indebted to Dr. Ed Theriot, Great Lakes Research Division, for help with the Latin diagnoses.

Recent collections from fresh-water habitats in Oregon (U.S.A.) have yielded two species of Comphoneis, which are described below. MATERIALS AND METHODS Material was collected by the senior author from the Metolius River and neighboring unnamed tributaries in the Camp Sherman Area, Jefferson County, Oregon, and Linton Lake and its environs in the McKenzie Pass Area, Lane County, Oregon (U.S.A.). Collections were cleaned in nitric acid and processed according to procedures described by Patrick & Reimer (1966), or cleaned and processed according to the method of van der Werff (1955). Cleaned material was air-dried onto coverslips and mounted in Hyrax or Cumarone R-9 (Holmes et al., 1981) and observed with a Leitz Dialux-20 or Ortholux light microscope outfitted with bright-field optics. For scanning electron microscopy (SEM), cleaned material was air-dried onto coverslips, which then were mounted onto aluminum stubs. Stubs bearing the cleaned material were sputter-coated with approximately 15 nm of goldpalladium and viewed with an ISI DS-130 scanning electron microscope, operated at 10-15 kV.

Luxury Consumption of Phosphorus by Five Cladophora Epiphytes in Lake Huron

The stainable polyphosphate bodies in five species of algae epiphytic on Cladophora glomerata were enumerated. The algal populations, two species of diatoms, two species of blue-green algae, and a red alga, were collected at various distances from a point source of phosphorus enrichment in Lake Huron. Populations assayed had accumulated polyphosphate bodies and exhibited different levels of maximum polyphosphate body abundance. Numbers of polyphosphate bodies per unit cell volume were least in the diatoms, greatest in the blue-greens, and intermediate in the red alga. No significant differences were found between subpopulations of the same species growing in different portions of the epiphyte community matrix at one location. The subpopulation growing at the location farthest from the point source of phosphorus had substantially fewer polyphosphate bodies than subpopulations of the same species closer to the point source. The ecology and growth relationships of Cladophora communities in the Laurentian Great Lakes has been studied extensively, largely because of the potential for offensive overgrowth in localities receiving phosphorus enrichment. Although abundance of Cladophora generally is related to phosphorus loading, certain aspects of seasonal growth apparently are mediated by other factors. Presently it is not clear if the commonly observed mid-summer decline in Cladophora growth is due to genetically pre-determined maturation effects, or to competition for critical resources by epiphytic communities which develop upon the maturing Cladophora stands. Due to the complex and highly structured form of the community developed upon Cladophora, the latter aspect of Cladophora ecology is difficult to address experimentally. In the following, we report the results of an investigation of one possibly important competitive process, sequestering of phosphorus beyond immediate growth requirements by populations epiphytic on Cladophora. Several specific questions were considered: (1) is there appreciable luxury consumption of phosphorus by epiphyte communities; (2) is the amount of phosphorus sequestered dependent upon ambient phosphorus levels; (3) is this ability to sequester phosphorus restricted to, or more prevalent in, certain major autecological groups of epiphytic organisms; 1 We thank L.

Lake Texoma Caddisflies (Insecta: Trichoptera): 1. Species Present and Faunal Changes Since Impoundment

In light-trap collections 1974-1977, 26 species of caddisflies were collected at Lake Texoma, Texas and Oklahoma. The lentic Cyrnellus fraternus (Banks), Hydroptila waubesiana Betten, and Oecetis inconspicua (Walker) numerically dominated; however, many typical lotic species were present with their larvae occupying the rocky, wave-swept margins of the lake. Greater numbers of species were collected than in earlier studies of Lake Texoma. Oecetis inconspicua adults were parasitized by the unionicolid water mite Koenikea nr wolcotti. The purpose of this study is to describe the Trichoptera or caddisfly fauna of Lake Texoma, a major impoundment in the southwestern United States. This is the first of a series of papers that will analyze the dynamics of the caddisfly community. Community is in the sense of Pielou (1975) where similar species occurring together form a loosely interrelated aggregate, a definition most similar to the term taxocene as proposed by Kownacki (1971). The caddisfly communities of lakes and reservoirs have received scant attention other than in species descriptions and faunal lists. Neave (1934), Marshall (1939), Milne (1943), and Corbet and Tjonneland (1955) analyzed flight patterns of selected lake species, while Neave (1933), Morgan (1956), and Winterbourn (1971a, 1971b) emphasized life history studies of lentic caddisflies. Considerably more literature exists on caddisflies in running waters, probably due to the relatively few species that occur in lentic waters and the difficulties in examining larval caddisfly habitats that cannot be effectively samples with grabs or cores. However, even in lake and pond environments, caddisflies are important in the diet of fishes. 1 Division of Entomology and Parasitology, University of California, Berkeley, California 94720. 2 Great Lakes Research Division, University of Michigan, Ann Arbor, Michigan 48109.
