Consideration of wave fields incident on boundaries between anelastic media shows that scattered wave fields experience reductions in phase and energy speeds, increases in maximum attenuation and<span>&nbsp;</span><i>Q</i><sup>−1</sup>, and directions of maximum energy flow distinct from phase propagation. Each of these changes in physical characteristics are shown to vary with angle of incidence. Finite relaxation times for anelastic media result in energy flow due to interaction of superimposed radiation fields and contribute to energy flow across anelastic boundaries for all angles of incidence. Agreement of theoretical and numerical results with laboratory measurements argues for the validity of the theoretical and numerical formulations incorporating inhomogeneous wave fields. The agreement attests to the applicability of the model and helps confirm the existence of inhomogeneous body waves and their associated set of distinct physical characteristics in the earth. The existence of such body waves in layered, low-loss anelastic solids implies the need to reformulate some seismological models of the earth. The exact anelastic formulation for a liquid-solid interface with no low-loss approximations predicts the existence of a range of angles of incidence or an anelastic Rayleigh window, through which significant amounts of energy are transmitted across the boundary. The window accounts for the discrepancy apparent between measured reflection data presented in early textbooks and predictions based on classical elasticity theory. Characteristics of the anelastic Rayleigh window are expected to be evident in certain sets of wide-angle, ocean-bottom reflection data and to be useful in estimating<span>&nbsp;</span><i>Q</i><sup>−1</sup><span>&nbsp;</span>for some ocean bottom reflectors.</p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB091iB11p11503","usgsCitation":"Borcherdt, R.D., Glassmoyer, G., and Wennerberg, L., 1986, Influence of welded boundaries in anelastic media on energy flow, and characteristics of P, S-I, and S-II waves: Observational evidence for inhomogeneous body waves in low-loss solids: Journal of Geophysical Research B: Solid Earth, v. 91, no.

The average total harvests of SC (47.7%) and SW (46.7%) strains were similar and ranked highest among the five strains; however, no strain showed statistical superiority in all four streams. Harvest of the MC strain was consistently and significantly lower than the other four strains within each stream and averaged 25.6%.

Differences in natural mortality rate, growth, and downstream movement among strains in a fifth, unfished, stream were not significant. Condition factor (<i>K</i>) decreased significantly for all five strains in an unfished stream. The MC strain appeared to be poorly suited for put-and-take streams, while SW and SC strains performed about equally well and are worthy of further evaluation in stocked stream environments.

Average time invested in foraging ranged from 11 to 71% among viewing areas (1-2 km of coastline) and from 21 to 28% among study areas (8-10 km of coastline). Foraging time budgets were unrelated to season or the length of time that an area had been inhabited by otters. The diet of sea otters in California consisted almost entirely of marine invertebrates. These patterns were consistent with our review of other information on sea otter activity and diet in California. Diurnal foraging patterns were distinctly crepuscular at all sites and times sampled but one. Afternoon peaks in foraging activity were greater than morning peaks. Time budgets and diets were similar to those of sea otter populations in Alaska and the Soviet Union that were known to be below equilibrium density, thus suggesting that the presently curtailed growth of the California sea otter population is not due to food limitation.</p>","language":"English","publisher":"Wiley","doi":"10.2307/3800973","usgsCitation":"Estes, J.A., Underwood, K.E., and Karmann, M.J., 1986, Activity-time budgets of sea otters in California: Journal of Wildlife Management, v. 50, no. 4, p. 626-636, https://doi.org/10.2307/3800973.","productDescription":"11 p.","startPage":"626","endPage":"636","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":131776,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"central California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -122.19192625120525,\n              36.72259570079257\n            ],\n            [\n              -122.19192625120525,\n              34.95799110626237\n            ],\n            [\n              -120.60794694715528,\n              34.95799110626237\n            ],\n            [\n              -120.60794694715528,\n              36.72259570079257\n            ],\n            [\n              -122.19192625120525,\n              36.72259570079257\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"50","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699c28","contributors":{"authors":[{"text":"Estes, James A. jim_estes@usgs.gov","contributorId":53325,"corporation":false,"usgs":true,"family":"Estes","given":"James","email":"jim_estes@usgs.gov","middleInitial":"A.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true},{"id":6949,"text":"University of California, Santa Cruz","active":true,"usgs":false}],"preferred":false,"id":315631,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Underwood, Karen E.","contributorId":81452,"corporation":false,"usgs":true,"family":"Underwood","given":"Karen","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":315632,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Karmann, Margit J.","contributorId":89096,"corporation":false,"usgs":true,"family":"Karmann","given":"Margit","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":315633,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

As such, knowledge about the conditions that provide favorable habitat for a species, and those that do not, is necessary for successful implementation of the methodology. In the context of IFIM, this knowledge is defined as habitat suitability criteria: characteristic behavioral traits of a species that are established as standards for comparison in the decision-making process.</p>\n<br/>\n<p>Habitat suitability criteria may be expressed in a variety of types and formats. The type, or category, refers to the procedure used to develop the criteria. Category I criteria are based on professional judgment, with little or no empirical data. Category II criteria have as their source, microhabitat data collected at locations where target organisms are observed or collected. These are called “utilization” functions because they are based on observed locations that were used by the target organism. These functions tend to be biased by the environmental conditions that were available to the fish or invertebrates at the time they were observed. Correction of the utilization function for environmental availability creates category III, or “preference” criteria, which tend to be much less site specific than category II criteria.</p>\n<br/>\n<p>There are also several ways to express habitat suitability in graphical form.  The binary format establishes a suitable range for each variable as it pertains to a life stage of interest, and is presented graphically as a step function.  The quality rating for a variable is 1.0 if it falls within the range of the criteria, and 0.0 if it falls outside the range.  The univariate curve format established both the usable range and the optimum range for each variable, with conditions of intermediate usability expressed along the portion between the tails and the peak of the curve.  Multivariate probability density functions, which can be used to compute suitability for several variables simultaneously, are conveyed as three dimensional figures with suitability on the z-axis, and two independent variables on the x-y plane.  These functions are useful for incorporating interactive terms between two or more variable.  Such interactions can also be demonstrated using conditional criteria, which are stratified by cover type or substrate size.  Conditional criteria may be of any category or format, but are distinguishable by two or more sets of functional relationships for each life stage.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Instream Flow Information Paper #21","largerWorkSubtype":{"id":9,"text":"Other Report"},"language":"English","publisher":"USDI Fish and Wildlife Service","publisherLocation":"Washington, D.C.","usgsCitation":"Bovee, K.D., 1986, Development and evaluation of habitat suitability criteria for use in the instream flow incremental methodology, 235 p.","productDescription":"235 p.","numberOfPages":"235","costCenters":[],"links":[{"id":292666,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f5b64de4b09d12e0e8e68b","contributors":{"authors":[{"text":"Bovee, Ken D.","contributorId":100447,"corporation":false,"usgs":true,"family":"Bovee","given":"Ken","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":498891,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Network habitat analysis refers to the evaluation of an entire river basin (or network) by predicting its habitat response to alternative management regimes.  The analysis principally focuses on the biological and hydrological components of the riv er basin, which include both micro- and macrohabitat.  (The terms micro- and macrohabitat are further defined and discussed later in this document.)  Both conceptual and analytic models are frequently used for simplifying and integrating the various components of the basin.  The model predictions can be used in developing management recommendations to preserve, restore, or enhance instream fish habitat.</p>\n<br/>\n<p>A network habitat analysis should begin with a clear and concise statement of the study objectives and a thorough understanding of the institutional setting in which the study results will be applied.  This includes the legal, social, and political considerations inherent in any water management setting.  The institutional environment may dictate the focus and level of detail required of the study to a far greater extent than the technical considerations.  After the study objectives, including species on interest, and institutional setting are collectively defined, the technical aspects should be scoped to determine the spatial and temporal requirements of the analysis.  A macro level approach should be taken first to identify critical biological elements and requirements.  Next, habitat availability is quantified much as in a \"standard\" river segment analysis, with the likely incorporation of some macrohabitat components, such as stream temperature.  Individual river segments may be aggregated to represent the networkwide habitat response of alternative water management schemes.  Things learned about problems caused or opportunities generated may be fed back to the design of new alternatives, which themselves may be similarly tested.  One may get as sophisticated an analysis as the decisionmaking process demands.</p>\n<br/>\n<p>Figure 1 shows a decision point that asks whether the results from the micro- or macrohabitat models display cumulative or synergistic effects.  If they do, then network habitat analysis is the appropriate tool.  We are left, however, in a difficult bind.  We may not know a priori whether the effects are cumulative or synergistic unless some network-type questions are investigated as part of the scoping process.  The next several sections raise issues designed to alert the modeler to relevant questions necessary to address this paradox.</p>","language":"English","publisher":"National Ecology Center","publisherLocation":"Washington, D.C.","usgsCitation":"Bartholow, J.M., and Waddle, T.J., 1986, Introduction to stream network habitat analysis, ix, 242 p.","productDescription":"ix, 242 p.","numberOfPages":"251","costCenters":[],"links":[{"id":292742,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53f707dee4b05ec1f2431bef","contributors":{"authors":[{"text":"Bartholow, John M.","contributorId":77598,"corporation":false,"usgs":true,"family":"Bartholow","given":"John","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":498974,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Waddle, Terry J.","contributorId":43430,"corporation":false,"usgs":true,"family":"Waddle","given":"Terry","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":498973,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

While a varying soil-water pressure was imposed on a thin sample by means of flexible membranes held in firm contact with the soil, water content was measured by gamma-ray attenuation, and matric potential was measured with tensiometers. The applied pressure was cycled through a program designed to obtain hysteretic θ(ψ) main and scanning curves. Isothermal characteristics were measured for 181-µm glass beads, Plainfield (Typic Udipsamments) sand, and an undisturbed core of Plano (Typic Argiudolls) silt loam at several temperatures in the 4° to 50°C range.

A model has been developed to quantify the temperature dependence as a function of θ. Combined with an isothermal hysteresis model of Mualem, this model requires only three characteristic functions to represent all hysteretic θ(ψ) curves for a given medium at all temperatures. Model calculations for the sand and silt loam data indicate that except near saturation, the temperature effect is greater than can be accounted for by the temperature dependence of the surface tension of pure water. The results rule out several possible explanations but they support the hypothesis that the concentration and effectiveness of dissolved surfactants increases with temperature.</span></p>","language":"English","publisher":"Wiley","doi":"10.2136/sssaj1986.03615995005000050004x","issn":"03615995","usgsCitation":"Nimmo, J., and Miller, E., 1986, The temperature dependence of isothermal moisture vs. potential characteristics of soils: Soil Science Society of America Journal, v. 50, no. 5, p. 1105-1113, https://doi.org/10.2136/sssaj1986.03615995005000050004x.","productDescription":"9 p.","startPage":"1105","endPage":"1113","costCenters":[],"links":[{"id":225455,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"50","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb0ebe4b08c986b325123","contributors":{"authors":[{"text":"Nimmo, J.

In addition to providing direct empirical evidence of a relationship between sulphur emissions and aquatic chemistry, these results suggest that there are significant regional differences in the fraction of deposited sulphur retained in basin soils and vegetation.</span></p>","language":"English","publisher":"Springer Nature","doi":"10.1038/322722a0","issn":"00280836","usgsCitation":"Smith, R.A., and Alexander, R.B., 1986, Correlations between stream sulphate and regional SO2 emissions: Nature, v. 322, no. 6081, p. 722-724, https://doi.org/10.1038/322722a0.","productDescription":"3 p.","startPage":"722","endPage":"724","costCenters":[],"links":[{"id":224045,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"322","issue":"6081","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fc4de4b0c8380cd4e204","contributors":{"authors":[{"text":"Smith, R.

A second correlation was tried eliminating data points 1, 3, and 5 which fell too low in the first trial.

The neutron logs profile, which is like a type of harmonic curve seems to be affected by an undefined factor. Analyzing the shape of the neutron profile it is inferred that hysteresis is the most probable phenomena that is affecting this moisture content profile. Although correlating neutron logs to moisture content is not a straight forward procedure, with an appropriate analysis, calibrated neutron logging tools can be used to determine the moisture content within the unsaturated zone of aquifers. Moisture content should be determined for calibration purposes at least at every foot of depth. Measurements of other elements or factors which may produce the harmonic curve effect might be included in further studies.&nbsp;</span></p>","largerWorkType":{"id":24,"text":"Conference Paper"},"largerWorkTitle":"Proceedings of the Third Caribbean Islands Water-Resources Congress","largerWorkSubtype":{"id":19,"text":"Conference Paper"},"conferenceTitle":"Third Caribbean Islands Water-Resources Congress","conferenceDate":"July 22-25, 1986","conferenceLocation":"U.S. Virgin Islands","language":"English","publisher":"Puerto Rico Water Resources Association","publisherLocation":"San Juan, P.R","usgsCitation":"Quinones-Aponte, V., and Carrasquillo, R., 1986, Use of borehole neutron logs to estimate moisture content in the unsaturated zone of an alluvial aquifer, <i>in</i> Proceedings of the Third Caribbean Islands Water-Resources Congress, U.S. Virgin Islands, July 22-25, 1986, p. 57-60.","productDescription":"4 p.","startPage":"57","endPage":"60","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":156,"text":"Caribbean Water Science Center","active":true,"usgs":true}],"links":[{"id":322029,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57500782e4b0ee97d51bb810","contributors":{"editors":[{"text":"Quinones, Ferdinand","contributorId":44138,"corporation":false,"usgs":true,"family":"Quinones","given":"Ferdinand","email":"","affiliations":[],"preferred":false,"id":631279,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Sanchez, A.V.","contributorId":94731,"corporation":false,"usgs":true,"family":"Sanchez","given":"A.V.","email":"","affiliations":[],"preferred":false,"id":631280,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Smith, H.","contributorId":48583,"corporation":false,"usgs":true,"family":"Smith","given":"H.","affiliations":[],"preferred":false,"id":631281,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Quinones-Aponte, Vicente","contributorId":48552,"corporation":false,"usgs":true,"family":"Quinones-Aponte","given":"Vicente","email":"","affiliations":[],"preferred":false,"id":631277,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carrasquillo, Ramon A.","contributorId":100815,"corporation":false,"usgs":true,"family":"Carrasquillo","given":"Ramon A.","affiliations":[],"preferred":false,"id":631278,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
