Forms that decline sharply were the largest cladocerans (Leptodora kindtii, Daphnia galeata, and D. retrocurva), the largest calanoid copepods (Limnocalanus macrurus, Epischura lacustris, and Diaptomus sicilis), and the largest cyclopoid copepod (Mesocyclops edax). Two of these, D. galeata and M. edax (both abundant in 1954), became extremely rare. Certain medium-sized or small species increased in numbers: Daphnia longiremis, Holopedium gibberum, Polyphemus pediculus, Bosmina longirostris, Bosmina coregoni, Ceriodaphnia sp., Cyclops bicuspidatus, Cyclops vernalis, and Diaptomus ashlandi. Evidence is strong that the changes were due to selective predation by alewives. The alewife was uncommon in southeastern Lake Michigan in 1954 but had increased to enormous proportions by 1966; there was a massive dieoff in spring 1967, and abundance remained relatively low in 1968. The composition of zooplankton populations in 1968 generally had shifted back toward that of 1954, although D. galeata and M. edax remained rare. The average size, and size at onset of maturity, of D. retrocurva decreased noticeably between 1954 and 1966 but increased between 1966 and 1968.</p>","language":"English","publisher":"Wiley","doi":"10.4319/lo.1970.15.4.0556","usgsCitation":"Wells, L., 1970, Effects of alewife predation on zooplankton populations in Lake Michigan: Limnology and Oceanography, v. 15, no. 4, p. 556-565, https://doi.org/10.4319/lo.1970.15.4.0556.","productDescription":"10 p.","startPage":"556","endPage":"565","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":480290,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.4319/lo.1970.15.4.0556","text":"Publisher Index Page"},{"id":132983,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"4","noUsgsAuthors":false,"publicationDate":"2003-12-22","publicationStatus":"PW","scienceBaseUri":"4f4e4ad8e4b07f02db684761","contributors":{"authors":[{"text":"Wells, LaRue","contributorId":75476,"corporation":false,"usgs":true,"family":"Wells","given":"LaRue","email":"","affiliations":[],"preferred":false,"id":308520,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Some tools are quite unsuited to certain questions and some questions cannot be answered without the appropriate tool.</p><p>There has been in recent years a large amount of discussion about whether the high costs and the extensive time period required for experimental watershed* research is really worth the investment. Recent discussions of this matter have cited as major criticisms of the instrumented basin that they are expensive, they leak water, they are unrepresentative, they produce changes too small for detection, and it is difficult to transfer the results. (See Hewlett, Lull, and Reinhart, 1969.) These are all questions worth talking about, but in one sense they tend to obscure the main issue. The main issue is what do we want to learn? If we can decide what it is we want to know, then we can logically ask ourselves what is the best way of going about obtaining that knowledge. It is in this context that we are most likely to place the experimental watershed in a useful and logical position in a classification of research methods.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Colloque de Wellington Symposium, 1970, Results of Research on Representative and Experimental Basins (IASH Publication 97)","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"International Symposium on the Results of Research on Representative and Experimental Basins","conferenceDate":"December 1-8, 1970","conferenceLocation":"Wellington, New Zealand","language":"English","publisher":"International Association of Scientific Hydrology","usgsCitation":"Leopold, L.B., 1970, Hydrologic research on instrumented watersheds, <i>in</i> Colloque de Wellington Symposium, 1970, Results of Research on Representative and Experimental Basins (IASH Publication 97), Wellington, New Zealand, December 1-8, 1970, p. 135-150.","productDescription":"16 p.","startPage":"135","endPage":"150","costCenters":[],"links":[{"id":338535,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":338530,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://iahs.info/Publications-News/paper-search.do","linkHelpText":"Paper can be found using the Search function"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58dcc823e4b02ff32c68576c","contributors":{"authors":[{"text":"Leopold, Luna Bergere","contributorId":93884,"corporation":false,"usgs":true,"family":"Leopold","given":"Luna","email":"","middleInitial":"Bergere","affiliations":[],"preferred":false,"id":686748,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Structurally the county is in the northern part of the Iowan Basin, and the sedimentary units of Cambrian through Devonian age dip southward at 9 to 14 feet per mile. Three major glacial advances, the Nebraskan, Kansan, and Wisconsin, covered all or part of the county during the Pleistocene Epoch and left behind glacial drift consisting of 0 to 125 feet of till and related outwash deposits. De posits of Holocene age, aside from surficial soil, are thin and scattered.</p><p>Ground water occurs in the sedimentary units of Cambrian through Mississippian age and in the glacial drift and outwash deposits of Quaternary age. The chief aquifers, in ascending order, are the deep Cambrian sandstones, Jordan aquifer, St. Peter Sandstone, Devonian and Mississippian limestones and dolomites, and the Pleistocene glacial drift and related interglacial deposits. Units between the St. Peter Sandstone and the Devonian limestones, the Platteville, Decorah, Galena, and Maquoketa Formations, are of low permeability and are considered to be an aquiclude in comparison to the overlying and under lying units.</p><p>The deep Cambrian sandstones will yield about 60 gpm (gallons per minute) to an individual well; the Jordan aquifer about 1,200 gpm; the St. Peter Sandstone 30 to 200 gpm; the Devonian limestones and dolomites 120 to 200 gpm; and the glacial outwash or shallow bedrock generally will yield 10 gpm or more. The Jordan aquifer supplies large quantities of water for municipal and industrial use at Mason City. Pumping tests on wells tapping the Jordan in that area show that the aquifer has a transmissibility of about 35,000 gallons per day per foot and a storage coefficient of 2 x 10<sup>-4</sup>&nbsp;Pumping in the Mason City&nbsp;area from 1912 to 1969 has produced about 200 feet of draw down in the areas of maximum withdrawal.</p><p>Ground water in Cerro Gordo County is of suitable chemical quality for domestic, industrial, or municipal use. The total dis solved solids ranges from 152 mg/l (milligrams per liter) in water from the shallow bedrock to 885 mg/l in water from the deep Cambrian sandstones. Water from the Jordan, which is the most productive aquifer in the county, generally contains less than 500 mg/l dissolved solids.</p><p>Ground water is the major source of water supplies throughout Cerro Gordo County. The majority of wells in the county are used for domestic and stock supplies, but the largest withdrawals of water are for municipal and industrial supplies. Municipal pumpage in the county in 1968 was about 1.5 billion gallons; industrial pumpage was about 1.8 billion gallons and most of the water was obtained from the Jordan aquifer.

Over the next year they declined by about 50%. These changes are explained in terms of annual differences in fecundity and survival. Most females laid five clutches of eggs in 1966, but only two or three clutches in 1967. Adult survival between 1966 and 1967 was better than during the following year. The capacity for increase, rc, was estimated as 0.0327/month, and cohort generation time, Tc, as 15.32 months from the 1966-67 data. Data from other natural populations of lizards are reviewed and the inferred net reproductive rates (Ro) compared with the history of the populations.

The isotopic chemistry of a travertine-depositing spring","docAbstract":"<p>The isotopic compositions of the travertine and of the hot spring solutions were studied at Main Springs and New Highland Terrace in the Mammoth Hot Springs area of Yellowstone Park. The springs issue at 74°C and a pH of 6.65 and the carbon isotopic composition of the travertine depositing at the orifice is +2%.δC<sup>13</sup><span>&nbsp;</span>(PDB). As the water travels out from the orifice, it cools and loses CO<sub>2</sub>. The travertine depositing at lower temperature is enriched in C<sup>13</sup>, reaching values of +4.8%. and the solution has a pH of 8.2 at 27°C. The δC<sup>13</sup><span>&nbsp;</span>of the carbon species in solution is about −2.3%. at 74° and about +4.3 at 27°C. Therefore, the difference in δC<sup>13</sup><span>&nbsp;</span>between the solid and solution is approximately 4%. at 74° and decreases to zero at about 20°C. These differences are shown to be due to kinetic (non-equilibrium) factors. The δO<sup>18</sup><span>&nbsp;</span>contents of the travertine and water show that in most samples the carbonate oxygen is in equilibrium with the water O<sup>18</sup><span>&nbsp;</span>at the temperatures of deposition. This is especially true for travertine depositing slowly and at temperatures above about 50°C. Calculations based on pH and alkalinity titrations of the hot spring waters<span>&nbsp;</span><i>in situ</i><span>&nbsp;</span>show that at the spring orifice the water is very high in free CO<sub>2</sub>, which is quickly lost in transit. The springs are supersaturated with respect to both aragonite and calcite during most of their travel in the open air.</p><p>The carbon isotopic composition of the travertine is similar to that in the marine carbonates that are adjacent to the springs and that are the probable source of the calcium carbonate.</p><p>The travertine from inactive prehistoric springs near Mammoth has similar δC<sup>13</sup><span>&nbsp;</span>and O<sup>18</sup><span>&nbsp;</span>to that from the active springs.

Results of deep drilling, from 4000 to 7000 meters or more, during the past decade however, define very sharp increases in geothermal gradient which are associated with the occurrence of abnormally high interstitial fluid pressure (geopressure). Bounded by regional growth faults along the landward margin of the Gulf Basin, the geopressured zone extends some 1300 km from the Rio Grande (at the boundary between the United States and Mexico) to the mouth of the Mississippi river. Gulfward, it extends to an unknown distance across the Continental Shelf.</p><p>Within geopressured deposits, geothermal gradients range upwards to 100 °C/km, being greatest within and immediately below the depth interval in which the maximum pressure gradient change occurs. The 120 °C isogeotherm ranges from about 2500 to 5000 m below sea level, and conforms in a general way with depth of occurrence of the top of the geopressured zone.

The two insecticides found in all Great Lakes fish have been DDT (DDT, DDD, DDE) and dieldrin. Fish from Lake Michigan contain from 2 to 7 times as much of these insecticides as those from the other Great Lakes. Insecticide levels calculated on a whole-fish basis show a marked difference from species to species. Within a species there is also an increase in DDT and dieldrin levels with an increase in size. If these insecticide levels are, however, calculated as ppm of insecticide in the extractable fish oil, the differences in concentration between species and the differences between size groups becomes considerably less. Laboratory experiments indicate that fish can build up concentrations of DDT and dieldrin at the parts-per-million level from parts-per-trillion concentrations in the water.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pesticides Monitoring Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Out-of-print","usgsCitation":"Reinert, R.E., 1970, Pesticide concentrations in Great Lakes fish: Pesticides Monitoring Journal, v. 3, no. 4, p. 233-240.","productDescription":"p. 233-240","startPage":"233","endPage":"240","numberOfPages":"7","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":130476,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269747,"type":{"id":11,"text":"Document"},"url":"https://biodiversitylibrary.org/page/26094207"}],"volume":"3","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db68838e","contributors":{"authors":[{"text":"Reinert, Robert E.","contributorId":101214,"corporation":false,"usgs":true,"family":"Reinert","given":"Robert","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":308382,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
