Recent unpublished data on mortality, Florida boat registrations, size of certain manatee wintering populations, and records outside of Florida are also given. Manatees never regularly occurred outside of Florida, except during the summer in Georgia.  Current distribution is also limited largely to Florida and coastal Georgia in summer, with extralimital records in other southeastern states.  In winter the range contracts and is centered around warm water sources in Florida.  The historical record on past abundance is inconclusive, but does not provide any compelling evidence to claim that manatees ever nearly became extinct.  There are no satisfactory means to estimate manatee population size.  However, within Florida, manatees have become more widespread and possibly more abundant during the past 30 years due to protection, greater availability of warm water in winter, and in some areas, increased exotic vegetation.  Deliberate killing for food was long a historical pressure on manatee populations in Florida, but is not almost non-existent.  Nevertheless, recent increasing trends in accidental mortality caused by boats, coupled with an understanding of manatee population dynamics, suggests that the future for manatees is not secure.  Ample justification exists for continued manatee conservation efforts.","largerWorkTitle":"Proceedings of the Third Southeastern Nongame and Endangered Wildlife Symposium","conferenceTitle":"Third Southeastern Nongame and Endangered Wildlife Symposium","conferenceDate":"1987-08-08T00:00:00","conferenceLocation":"Athens, GA","language":"English","publisher":"Georgia Dept. of Natural Resources, Game and Fish Division","publisherLocation":"Social Circle, GA","usgsCitation":"O'Shea, T., 1988, The past, present, and future of manatees in the southeastern United States: realities, misunderstandings and enigmas, 21 p.","productDescription":"21 p.","numberOfPages":"21","costCenters":[],"links":[{"id":293107,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53fef0efe4b01f35f8fd6a57","contributors":{"authors":[{"text":"O'Shea, T.

In contrast to avian diversity analyses conducted at the same sites, species richness, relative diversity, and faunal similarity of small mammals were greater among upland rather than riparian communities across the cline. Beta diversity between riparian and upland small mammal communities is greater at higher elevations within the watershed. These higher elevation portions of watersheds must be emphasized in management strategies to conserve regional integrity of native small mammal faunas.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Management of amphibians, reptiles, and small mammals in North America: Proceedings of the symposium","largerWorkSubtype":{"id":9,"text":"Other Report"},"language":"English","publisher":"Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station","publisherLocation":"Fort Collins, CO","usgsCitation":"Olson, T., and Knopf, F., 1988, Patterns of relative diversity within riparian small mammal communities, Platte River Watershed, Colorado, 8 p.","productDescription":"8 p.","startPage":"379","endPage":"386","numberOfPages":"8","costCenters":[],"links":[{"id":292964,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109.0603,36.9924 ], [ -109.0603,41.0034 ], [ -102.0409,41.0034 ], [ -102.0409,36.9924 ], [ -109.0603,36.9924 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53fc4ddde4b0413fd75d6b17","contributors":{"authors":[{"text":"Olson, T.E.","contributorId":74690,"corporation":false,"usgs":true,"family":"Olson","given":"T.E.","email":"","affiliations":[],"preferred":false,"id":499322,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Knopf, Fritz L.","contributorId":30549,"corporation":false,"usgs":true,"family":"Knopf","given":"Fritz L.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":499321,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Over 80 percent of the normal discharge of approximately 3.4 m<sup>3</sup>/s (120 ft<sup>3</sup>/s) consists of effluent from the City of Las Vegas and Clark County sewage treatment plants.  Beginning in the 1950s, a large wetland area developed along the wash that supported waterfowl populations and contributed to some water quality transformations.  Heavy rains and subsequent flooding in the area in 1983 and 1984 resulted in erosion and channelization that greatly reduced the wetland area within Las Vegas Wash.  The reduction in wetland area shortened water travel time in the wash and affected water quality.  The primary impacts on the water entering Lake Mead have been an increase in temperature, a decrease in dissolved oxygen concentration, and an increase in ammonia levels.  Other physical-chemical parameters and changes in nutrient transformations are also discussed.","language":"English","publisher":"Taylor & Francis","publisherLocation":"Washington, D.C.","doi":"10.1080/07438148809354388","usgsCitation":"Roline, R.A., and Sartoris, J.J., 1988, Changes in the morphometry of Las Vegas Wash and the impact on water quality: Lake and Reservoir Management, v. 4, no. 1, p. 135-142, https://doi.org/10.1080/07438148809354388.","productDescription":"8 p.","startPage":"135","endPage":"142","numberOfPages":"8","costCenters":[],"links":[{"id":293067,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","otherGeospatial":"Las Vegas Wash","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.894888,36.123186 ], [ -114.894888,36.14121 ], [ -114.862873,36.14121 ], [ -114.862873,36.123186 ], [ -114.894888,36.123186 ] ] ] } } ] }","volume":"4","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53fef0cfe4b01f35f8fd6953","contributors":{"authors":[{"text":"Roline, Richard A.","contributorId":56984,"corporation":false,"usgs":true,"family":"Roline","given":"Richard","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":499533,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sartoris, James J.","contributorId":98018,"corporation":false,"usgs":true,"family":"Sartoris","given":"James","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":499534,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This fact has been known by biochemists for some time. However, use of chemical inhibitors of enzymic systems and membranes continues to be a common approach taken toward unraveling the biochemistry and biophysics of plants, animals, and microorganisms. Various types of “broad-spectrum” biochemical inhibitors (e.g., poisons, respiratory inhibitors, and uncouplers) have been employed by ecologists for many years in order to demonstrate the active participation of microbes in chemical reactions occurring in natural samples (e.g., soils, sediments, and water). In recent years, considerable advances have been made in our understanding of the biochemistry of microorganisms of biogeochemical interest. Concurrent with these advances have been the discoveries of novel types of compounds that will block the metabolism of one particular group of microbes, but have little disruptive effect on other physiological types. Thus, the term “specific inhibitor” has been applied to these types of compounds when they are used to probe the functions of mixed populations of microorganisms. These substances provide powerful experimental tools for investigating the activity and function of certain types of microorganisms in natural samples.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Advances in microbial ecology","language":"English","publisher":"Springer","publisherLocation":"New  York","doi":"10.1007/978-1-4684-5409-3_8","usgsCitation":"Oremland, R.S., and Capone, D., 1988, Use of \"specific\" inhibitors in biogeochemistry and microbial ecology, chap. <i>of</i> Advances in microbial ecology, v. 10, p. 285-383, https://doi.org/10.1007/978-1-4684-5409-3_8.","productDescription":"99 p.","startPage":"285","endPage":"383","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":356567,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5c113026e4b034bf6a824e49","contributors":{"authors":[{"text":"Oremland, Ronald S. 0000-0001-7382-0147 roremlan@usgs.gov","orcid":"https://orcid.org/0000-0001-7382-0147","contributorId":931,"corporation":false,"usgs":true,"family":"Oremland","given":"Ronald","email":"roremlan@usgs.gov","middleInitial":"S.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":742906,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Capone, D.G.","contributorId":105876,"corporation":false,"usgs":true,"family":"Capone","given":"D.G.","email":"","affiliations":[],"preferred":false,"id":742907,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We use the results of surveys conducted annually during 1955-81 in major breeding areas to examine the factors that affect the distributions of 10 common North American duck species. Three patterns of settling are described: homing, opportunistic, and flexible. Homing is generally more pronounced among species that use more stable (more predictable) wetlands, such as the redhead (Aythya americana), canvasback (A. valisineria), lesser scaup (A. affinis), mallard (Anas platyrhynchos), gadwall (Anas strepera), and northern shoveler (Anas clypeata). Opportunistic settling is more prevalent among species that use less stable (less predictable) wetlands, such as northern pintail (Anas acuta) and blue-winged teal (Anas discors). Flexible settling is exhibited to various degrees by most species.The 10 species are shown to fall along a natural ordination reflecting different life history characteristics. Average values of indices of r- and K-selection indicated that pintail, mallard, blue-winged teal, and shoveler have the most features associated with unstable or unpredictable environments. Gadwall, American wigeon (Anas americana), and green-winged teal (Anas crecca) were intermediate, and attributes of the diving ducks were associated with the use of stable or predictable environments.Some species--notably mallard, gadwall, blue-winged teal, redhead, and canvasback--tend to fill available breeding habitat first in the central portions of their range, and secondly in peripheral areas. Other species--American wigeon, green-winged teal, northern shoveler, northern pintail, and lesser scaup--fill their habitat in the order it is encountered during spring migration.Age and sex classes within species vary in their settling pattern. Some of this variation can be predicted from the mating systems of ducks in which breeding females, especially successful ones, have a greater investment in habitat resources and are more likely to return to the same area in subsequent years.","language":"English","publisher":"The Wildlife Society","usgsCitation":"Johnson, D.H., and Grier, J., 1988, Determinants of breeding distributions of ducks: Wildlife Monographs, v. 100, 37 p.","productDescription":"37 p.","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":199140,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"100","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa8e4b07f02db6679a5","contributors":{"authors":[{"text":"Johnson, Douglas H. 0000-0002-7778-6641","orcid":"https://orcid.org/0000-0002-7778-6641","contributorId":70327,"corporation":false,"usgs":true,"family":"Johnson","given":"Douglas","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":326513,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grier, J.W.","contributorId":33277,"corporation":false,"usgs":true,"family":"Grier","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":326512,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The evidence is that (1) extant kelps occur exclusively in cold-water habitats; (2) all but one of 27 kelp genera occur in the North Pacific, 19 of these exclusively; and (3) limpets and herbivorous marine mammals obligately associated with kelps or other stipitate brown algae appeared late in the Cenozoic, even though more generalized forms of both groups are much older. We propose, further, that sea otters and perhaps other groups of benthic-feeding predatory mammals, whose late Cenozoic distributions all were limited to the North Pacific, created an environment for the evolution of kelps in which the intensity of herbivory was unusually low. We hypothesize that this interaction created predictable differences among habitats in the intensity of herbivory on several spatial scales, with resulting trade-offs between anti-herbivore defenses and plant competitive abilities in their respective floras. Sea otters incur time and energy costs for diving, resulting in depth-related reductions to foraging efficiency and thus increased sizes and densities of herbivorous sea urchins. Thus, the deep-water flora is well defended, but competitively subordinate, compared with the shallow-water flora. Similarly, we argue that during the same period of earth history, predation had less of a limiting influence on herbivorous invertebrates in the temperate southwestern Pacific. We hypothesize that (1) consequent biogeographical differences in the intensity of herbivory may have selected the phenolic-rich brown algal flora in temperate Australia/New Zealand; and (2) tightly coevolved plant/herbivore interactions may explain why Australian and New Zealand herbivores are undeterred by phenolics and why other classes of secondary compounds in the Australian/New Zealand flora significantly deter herbivores.<br data-mce-bogus=\"1\"></p>","language":"English","publisher":"Cambridge University Press","doi":"10.1017/S0094837300011775","usgsCitation":"Estes, J.A., and Steinberg, P., 1988, Predation, herbivory and kelp evolution: Paleobiology, v. 14, p. 19-36, https://doi.org/10.1017/S0094837300011775.","productDescription":"18 p.","startPage":"19","endPage":"36","numberOfPages":"18","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":130577,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","noUsgsAuthors":false,"publicationDate":"2016-04-08","publicationStatus":"PW","scienceBaseUri":"4f4e4b08e4b07f02db69ba61","contributors":{"authors":[{"text":"Estes, J.

Individual treatments in the applications included land purchase for waterfowl production, wetland easement purchase, lease of uplands for waterfowl management, cropland retirement, use of no-till winter wheat, delayed cutting of alfalfa, installation of nest baskets, nesting island construction, and use of predator-resistant fencing.The simulations predicted that implementation of the management plan would increase recruits by 24%. Nest baskets were the most effective treatment, accounting for 20.4% of the recruits. No-till winter wheat was the second most effective, accounting for 5.9% of the recruits. Wetland loss due to drainage would cause an 11% loss of breeding population in 10 years.The models were modified to account for migrational homing. The modification indicated that migrational homing would enhance the effects of management. Nest success rates were critical contributions to individual management methods. The most effective treatments, such as nest baskets, had high success rates and affected a large portion of the breeding population.Economic analyses indicated that nest baskets would be the most economical of the three techniques tested. The applications indicated that the system is a useful tool to aid management decisions, but data are scarce for several important variables. Basic research will be required to adequately model the effect of migrational homing and density dependence on production. The comprehensive nature of predictions desired by managers will also require that production models like the one described here be extended to encompass the entire annual cycle of waterfowl.","language":"English","publisher":"U.S. Fish and Wildlife Service","publisherLocation":"Washington, DC","usgsCitation":"Cowardin, L., Johnson, D.H., Shaffer, T., and Sparling, D.W., 1988, Applications of a simulation model to decisions in mallard management: Fish and Wildlife Technical Report 17, 29 p.","productDescription":"29 p.","startPage":"0","endPage":"28","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":198399,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac6e4b07f02db67a491","contributors":{"authors":[{"text":"Cowardin, L.M.","contributorId":106435,"corporation":false,"usgs":true,"family":"Cowardin","given":"L.M.","email":"","affiliations":[],"preferred":false,"id":325150,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, Douglas H. 0000-0002-7778-6641","orcid":"https://orcid.org/0000-0002-7778-6641","contributorId":70327,"corporation":false,"usgs":true,"family":"Johnson","given":"Douglas","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":325147,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Shaffer, T.L.","contributorId":98245,"corporation":false,"usgs":true,"family":"Shaffer","given":"T.L.","email":"","affiliations":[],"preferred":false,"id":325149,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sparling, D.

Aerial surveys are generally considered to be the most accurate method of counting manatees, although there is no doubt that some undetermined proportion is missed (Irvine and Campbell 1978, Shane 1981, Kinnaird 1985, Packard et al. 1985). When designing aerial censuses for manatees two types of aircraft are usually considered: fixed-wing and rotary-wing airplanes (Irvine 1982). Fixed-wing airplanes normally are used because helicopters are prohibitively expensive to hire (often over twice that of a fixed-wing airplane). Helicopters, however, have been assumed to yield more accurate counts for manatees (personal observations; J. Fletemeyer and J. Provancha, personal communication) because their slower air speed and greater maneuverability reduce the proportion of animals missed due to some of the biases inherent in fixed-wing airplane counts (Caughley 1974). To assess how effective fixed-wing aircraft are in determining the number of manatees in an area, a series of paired total-count aerial surveys were done in winter 1978-79.</p><p>A Bell 47G helicopter was used to obtain a “count” to compare with counts made from a Cessna 172 fixed, high-wing airplane. The experiment was conducted at two different sites and on five consecutive days at each site. The first location was Crystal River, which is a clear, spring-fed river that flows about11 km into the Gulf of Mexico on the central west coast of Florida. The second site was an 8-km-long section of the Indian River, which is a large, turbid estuary adjacent to Cape Canaveral on the east coast of Florida.&nbsp;</p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1748-7692.1988.tb00185.x","usgsCitation":"Rathbun, G.B., 1988, Fixed-wing airplane versus helicopter surveys of manatees
