Recruitment to animal populations can occur through both immigration and in situ reproduction. These two components of recruitment are conceptually distinct and lead to different mechanistic models of population dynamics. We describe a capture—recapture design that can be used to obtain separate estimates of two recruitment components. We then illustrate the use of our method and estimators with capture—recapture data from a population of Microtus pennsylvanicus at the Patuxent Wildlife Research Center in Maryland.

Although smooth pahoehoe textures are poorly characterized on the SIR-B data, rougher pahoehoe types and the a'a flow portion show image textures attributed to spatial variations in surface roughness. Field observations of six distinct lava flow textural units are described and used to interpret modes of emplacement. Terrain measurements of these units show that surface roughness differs across and along the flow, apparently due to shear during flow emplacement. The radar smooth/rough boundary between pahoehoe and a'a occurs at a vertical relief of -10 cm on this lava flow. While direct observation and measurement most readily yield information related to lava eruption and emplacement processes, analyses of remote sensing data such as those acquired by imaging radars and altimeters can provide a means of quantifying surface texture, identifying the size and distribution of flow components, and delineating textural unit boundaries.

Annual report 1989","docAbstract":"The goal of this project is to compare net-pen rearing methods to traditional hatchery methods of rearing upriver bright fall chinook salmon (Oncorhvnchus tshawvtscha). Fish were reared at several densities in net pens at three Columbia River backwater sites during 1984-1987, and in a barrier net at one site during 1984-1986; methods included both fed and unfed treatments. The purpose of this report is to summarize the results obtained from the unfed treatments and the current return of adults from all fed treatments and the barrier net. Zooplankton were the primary food item of unfed fish. Fish reared in net pens utilized insects colonizing the nets as an additional food source, whereas those reared in the barrier net did not. Growth and production of fish reared in the unfed treatments were low. Instantaneous growth rates of unfed fish were much lower than those of the fed treatments and hatchery controls except when zooplankton densities were high and chironomid larvae were important in the diet of unfed fish reared in pens. Only fish in the barrier net treatment resulted in consistent net gains in growth and production over the rearing periods. Adult returns of fish from all fed and unfed treatments are lower than those of control fish reared at the hatchery. Returns appear to be inversely related to rearing density. Even though adult returns are lower than those of traditional hatchery methods, a cost-benefit analysis, as return data becomes more complete, may prove these methods to be an economical means of expanding current hatchery production, particularly if \"thinning\" releases were used.

The metavolcanic remnants are similar in age to or are only slightly older than the voluminous enclosing batholithic rocks. Thus, high to surface levels of the batholith are implied for this region. This is interesting considering that deep-level (∼25 km) batholithic rocks of the same age as the metavolcanic rocks occur at the southern end of the range. Apparent structural continuity between these two regions suggests that the southern half of the range offers an oblique section through young (˜100 Ma) sialic crust.
The middle Cretaceous ages of the two volcanic sequences are indicated by U/Pb zircon and Rb/Sr bulk-rock isochron data. The two isotopic systems agree very closely with one another. Some of the U/Pb systems within the Boyden Cave pendant are discordant due to the inheritance or entrainment of Proterozoic zircon. This is a common phenomenon in volcanic or plutonic rocks erupted or emplaced within the Kings sequence metamorphic framework, a belt of distinct pendants with abundant continent-derived sedimentary protoliths. In conjunction with other petrochemical parameters, lavas and magmas of this framework domain are shown to be contaminated with sedimentary admixtures. The contaminated domain of the batholith reflects the bounds of the Kings sequence framework, which along its eastern margin probably represents a major pre-batholith to early batholith tectonic break.
The middle Cretaceous metavolcanic sequences were apparently built on two distinctly different early Mesozoic substrates separated by a major tectonic break. In the Boyden Cave pendant, the substrate may be represented by the shallow to deep-marine Kings sequence; to the east in the Oak Creek pendant, the substrate consists of a thick silicic ignimbrite sequence. In both areas the middle Cretaceous rocks and adjacent sequences share intense ductile deformation fabrics. Earlier views that considered these fabrics as an expression of Jurassic orogenic deformation are in error. Structural and age relations indicate that the fabrics developed between 105 and 100 Ma and during the medial phases of Cretaceous composite batholith growth.

The top of the reef is now 150–160 m below sea level. Radiocarbon and Useries dating indicates that it drowned about 13.9 ka by the combined effects of island subsidence (2.5 mm/year) and the rapid rise of sea level at the end of the last glaciation so that the relative submergence rate of more than 10 mm/year exceeded the upward growth rate of the reef. The submerged reef caps the offshore part of the southwest rift-zone ridge of Mauna Loa, which has apparently undergone little volcanic activity offshore since 170 ka, and possibly since 270 ka. This fact suggests that rift zone activity is becoming increasingly restricted toward the upper part of the volcano, a condition possibly heralding the end of the shield-building stage.

Dredge recovery indicates that the shallowest of these bands is a drowned coral reef, and the deeper bands are also inferred to be coral reefs. The reefs occur above a prominent submarine bench 1500–2500 m deep on the ridge (H-terrace) that marks the shoreline at the end of vigorous shield building of Haleakala volcano when lava flows ceased crossing and reworking the shoreline.
Since their growth these reefs have subsided as much as 2200 m and have tilted systematically about 20 m/km southward as a result of post-reef volcanic loading on the island of Hawaii, whose center of mass is about directly south of the Haleakala Ridge. The 234U/238U age of the dredged coral is
Basalt glass fragments dredged from the Haleakala Ridge below the H terrace are tholeiitic and contain high sulfur indicative of eruption in water deeper than 200 m. Basalt glass fragments associated with the reefs above the H terrace are dominantly tholeiitic and contain intermediate sulfur contents, indicative of subaqueous eruption in shallow, near-shore conditions. One alkalic glass fragment was recovered above the H terrace. These relations indicate that the morphologic end of shield building as recorded by construction of the H terrace was not accompanyed by a change from tholeiitic to alkalic basalt; instead tholeiite eruptions continued for some time before the erupted lava became alkalic.

Samples loaded at 45° to (001) exhibit gentle external rotations associated with dislocation glide. High‐angle kink bands in these samples, unlike those developed in micas loaded parallel to (001), are limited to sample corners. Samples shortened perpendicular to (001) show no evidence of nonbasal slip and fail by fracture over all conditions tested. The mechanical response of biotite shortened at 45° to (001) is nearly perfectly elastic‐plastic; stress‐strain curves are characterized by a steep elastic slope, a sharply defined yield point, and continued deformation at low (mostly 1%. Stresses measured beyond the yield point are insensitive to confining pressure over the range 200 to 500 MPa and exhibit weak dependencies upon strain rate and temperature. Assuming an exponential relationship between differential stress σ and strain rate of the form , the data collected over strain rates and temperatures of 10−7 to 10−4 s−1 and 20° to 400°C, respectively, are best fit by an exponential constant α of 0.41±0.08 MPa‐1 and an activation energy of 82±13 kJ/mol. A power law fits the data equally well with = 18±4 and = 51±9 kJ/mol. Samples oriented favorably for slip in directions [100] and [110] are measurably weaker than those shortened at 45° to [010] and [310], consistent with the reported Burgers vectors 〈100〉, 1/2 〈110〉, and 1/2 〈110〉. The anisotropy of biotite is further revealed by contrasting these plastic strengths with results of samples deformed parallel and perpendicular to (001). Previous studies have shown that biotite loaded in the (001) plane is strong prior to the nucleation of kink bands. The strength of biotite shortened perpendicular to (001) exceeds that measured parallel to (001) and is pressure dependent. Application of the results to deformation within the continental crust suggests that biotite oriented favorably for slip is much weaker than most other silicates over a wide range of geologic conditions. Its presence within foliated rocks and shear zones may limit locally the stresses that can be supported.

Despite wide variation in single physiognomic characters, overall trends can be used to distinguish between samples from different climates. Some climate parameters are well correlated with changes in physiognomy, so that climate characteristics can be inferred from physiognomic analyses. Here I apply this climate–leaf analysis multivariate program (CLAMP) to leaf assemblages from the Cretaceous/Tertiary boundary. The results indicate a fourfold increase in precipitation at the boundary and an increase in mean annual temperature of 10°C. These levels persisted for 0.5–1.0 Myr, after which preá-cipitation decreased to about three times the values for the latest Cretaceous, and the mean annual temperature decreased to 5–6°C above latest Cretaceous values.

In the Mohave Mountains and Aubrey Hills of Arizona and the eastern Whipple Mountains of California near Parker Dam, these deposits comprise four unconformity-bounded sequences composed of locally derived epiclastic and volcanic rocks and the Peach Springs Tuff. The three older sequences represent syntectonic units that were deposited coeval with detachment faulting, and the fourth is interpreted to be postextensional. The sequences are correlated between four fault-bounded regions, which are the remnants of four different depositional basins. Similar sequences can be correlated over broad areas of the extensional corridor despite the general lack of widespread units. The basins developed in about the same positions, relative to each other and to volcanic sources, as they occupy at present. This is shown by gradational changes of pre-Tertiary rock types between regions, systematic variations in the abundance of magmatic units, and correlative volcanic units that occur in two adjacent regions. The basins formed in the early Miocene from segmentation of the upper crust into blocks bounded by high-angle faults that trended both parallel and perpendicular to the direction of extension and which were terminated at middle crustal depths by a low-angle detachment fault. Extreme rotation of one large crustal block, which constitutes the central Mohave Mountains, is recorded by a major unconformity in the lower Miocene section of one basin. Because coeval sections that formed in adjoining basins do not record this rotation, the underlying crustal blocks must have been separated by transfer faults that allowed them to rotate independently. These proposed transfer faults are represented at present by major faults with trends that parallel the direction of extension on the Whipple detachment system.

Ungulate remains constituted a major portion of early-season scats, graminoids of May and June scats, and whitebark pine seeds of late-season scats. Berries composed a minor portion of scats during all months. The diet varied most among years during May, September, and October, and was most diverse during August. Defecation rates peaked in July and were low in April through June. Among-years differences in scat content were substantial; estimates of average scat composition took 4-6 years to stabilize. Major trends in diet were evident and reflected long-term variation. We suggest that long-term studies are necessary to adequately document bears' food habits in variable environments; the Yellowstone grizzly bears' diet varied with seasonal and yearly availability of high-quality foods, lack of berries and large fluctuations in the size of pine seed crops were major factors limiting bear density in the Yellowstone area, and the availability of edible human refuse buffered the limitations imposed by inadequate berry and pine seed crops prior to the 1970s.","language":"English","publisher":"Canadian Science Publishing","usgsCitation":"Mattson, D.J., Blanchard, B.M., and Knight, R.R., 1990, Food habits of Yellowstone grizzly bears, 1977-1987: Canadian Journal of Zoology, v. 69, p. 1619-1629.","productDescription":"11 p.","startPage":"1619","endPage":"1629","numberOfPages":"11","costCenters":[],"links":[{"id":293973,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho, Montana, Wyoming","otherGeospatial":"Yellowstone National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -111.156,44.1324 ], [ -111.156,45.109 ], [ -109.8242,45.109 ], [ -109.8242,44.1324 ], [ -111.156,44.1324 ] ] ] } } ] }","volume":"69","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54195136e4b091c7ffc8e6b1","contributors":{"authors":[{"text":"Mattson, David J. david_mattson@usgs.gov","contributorId":3662,"corporation":false,"usgs":true,"family":"Mattson","given":"David","email":"david_mattson@usgs.gov","middleInitial":"J.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":501354,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blanchard, Bonnie M.","contributorId":33633,"corporation":false,"usgs":true,"family":"Blanchard","given":"Bonnie","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":501355,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Knight, Richard R.","contributorId":68660,"corporation":false,"usgs":true,"family":"Knight","given":"Richard","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":501356,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70007060,"text":"70007060 - 1990 - Effect of size on lake trout survival after a single sea lamprey attack","interactions":[],"lastModifiedDate":"2012-10-02T17:16:14","indexId":"70007060","displayToPublicDate":"1990-01-02T12:10:00","publicationYear":"1990","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3624,"text":"Transactions of the American Fisheries Society","active":true,"publicationSubtype":{"id":10}},"title":"Effect of size on lake trout survival after a single sea lamprey attack","docAbstract":"When lake trout Salvelinus namaycush were subjected to a single attack by a sea lamprey Petromyzon marinus in laboratory tests in 1986, percentage mortality was significantly higher in small fish (64%; 469-557 mm; N = 67) than in medium (44%; 559-643 mm; N = 45) or large fish (43%; 660-799 mm; N = 47).

The K/T boundary in nonmarine rocks from New Mexico to Alberta is identified by the coincidence of a palynological extinction horizon and an iridium abundance anomaly. Plant microfossils provide evidence of the effects of the TCE and place constraints on theories of its cause. Changes in plant microfossil assemblages within intervals spanning the K/T boundary are evidence of abrupt and permanent changes in terrestrial, floras that were a consequence of the TCE; these changes are essentially independent of lithofacies. Extinction levels varied among major groups of plants (angiosperms, gymnosperms, and pteridophytes), but simultaneously affected different plant communities throughout the region. The abrupt nature of the extinction across western North America is consistent with the impact hypothesis; it is inconsistent with progressive change in paleoclimate possibly being the cause of the terminal Cretaceous extinctions. By causing the extinction of a significant portion of the Late Cretaceous flora of the region, the TCE influenced the development of the modern flora, but its effects appear to have been concentrated in western North America.

During the Holocene, glacially-derived sediments from the Copper River and other meltwater streams have been prograding seaward across the shelf, covering the glacial and glacimarine upper Yakataga diamicts that blanketed the shelf and accumulated on the upper slope seaward of the sea valleys during the Pleistocene. GLORIA imagery near Middleton Island provides a new perspective on the glacimarine depositional environment on the continental slope in a collision zone between the Pacific and North American plates. Southwest of Middleton Island, along the subduction margin, sinuous valleys funnel sediment around shelf-edge-parallel, subduction-created, anticlinal ridges that have deflected and locally trapped glacimarine sediment. The slope south and southeast of Middleton Island where oblique convergence occurs, is incised by dendritic, erosional gulley systems, contains no compressional ridges, and thus, the apparently active sediment pathways to the trench are unrestricted. However, below the sea valley mouths, apparently both glacial and glacimarine sediments blanket the upper slope, covering any dendritic gulley systems that may have formed during or since the Pleistocene low stands of sea level.

The calc-alkalic, metaluminous to peraluminous Chemehuevi Mountains Plutonic Suite exhibits crude normal, vertical, and temporal zonation. The zones are progressively younger and more felsic away from the roof and walls; the most differentiated material is concentrated toward the center and floor of the intrusion. Hornblende-biotite- and biotite granodiorite are metaluminous and form the outer margin of the intrusion along the northern and southern walls, and sill-like bodies in an older suite of granitoids and Proterozoic basement rocks. Locally these rocks bear a sub-horizontal, southwest-trending, mylonitic lineation, considered to be synchronous with regional mylonitic deformation. Later and more evolved units are subequigranular to porphyritic, metaluminous to weakly peraluminous biotite granodiorite to granite, and make up the greatest proportion of the intrusion. The youngest, most leucocratic members of the suite are undeformed, locally garnetiferous muscovite granite and granodiorite that form the central part of the intrusion.
Major, trace, and rare earth element data indicate that the magmas of the Cheme-huevi Mountains Plutonic Suite became progressively enriched in Si, K, Rb, Mn, Y, U, and heavy rare earth elements (REE). Fractional crystallization of some REE–rich accessory minerals was important in producing some of these trends. Although modest compositional breaks occur across internal contacts, the general continuity of trends from field, modal, and chemical data suggests that these rocks constitute a comagmatic intrusive suite. Estimates for the pressure of emplacement of the suite vary from 4 to 6 kbar, or a minimum depth of 12 km. Preliminary Pb-, Sr-, and oxygen-isotopic data, together with the REE chemistry, suggest that the Chemehuevi Mountains Plutonic Suite was derived from a heterogeneous crustal source. Compositional variations within the plutonic suite are consistent with open-system fractionation, involving fractional crystallization of discrete batches of magma derived from the melting of a heterogeneous crustal source under H2O-saturated conditions.

We found that selective principal component analysis (Chavez and Kwarteng 1989), on band ratios of near-IR/green, highlights changes in blue ice areas. The formation and preservation of blue ice is poorly understood, but we suggest that it generally takes longer to increase a blue ice area than to decrease it, and that blue ice extent is most sensitive to changes in accumulation rate. The investigated blue ice area shows a decrease in extent over the two-year period caused by incursion of snow that probably resulted from an increase in accumulation rate. Comparison of two TM images collected 18 days apart shows that transitory snow drifts have little effect on blue ice extent.

The SP and lower WCB intruded structurally lower ophiolitic mélange of the Marble Mountain terrane; the upper WCB intruded successively structurally higher metavolcanic and metasedimentary rocks of the western and eastern Hayfork terranes. The predominant volume of the system comprised a two-layer chamber in which an upper dacitic magma crystallized to form tonalite to granite in the upper WCB and a lower andesitic magma crystallized to form gabbro to tonalite in the lower WCB and SP. The upper part of the system had Sri, = 0.7043 and a range of δ18O from +8.7 to +11.2%o; the lower part had average Sri = 0.7046 and δ18O from +8.1 to +8.8%o The two layers of the system are separated by a transition zone that is intermediate in isotopie composition. The compositional differences between upper and lower parts of the system can be explained as (1) the result of intrusion of two separate pods of noncogenetic magma, or (2) the product of in situ assimilation-fractional crystallization. The second explanation requires that a relatively 87Sr-rich contaminant such as the structurally lower Marble Mountain terrane was assimilated in the lower part of the system, whereas an 18O-rich, generally 87Sr-poor contaminant such as the structurally intermediate western Hayfork terrane was assimilated by the upper part. Trace-element evidence suggests that gradational upward zoning (from gabbro to granite) resulted from an upward decrease in the efficiency of crystal-melt segregation and crystal accumulation. H2O-rich basaltic magma preceded development of the two-layer system, and basaltic pulses into the lower part of the system continued during most of its solidification history. Most basaltic rocks display evidence of some degree of fractional crystallization and interaction with crustal rocks; however, a few have low Sri and high concentrations of Cr and Ni, characteristics of undifferentiated mantle melts. Two-mica granite of the western Slinkard pluton cannot be related to the remainder of the system by fractional crystallization. High δ18O, high Ba, and low Sr abundances suggest that the two-mica granite is probably a partial melt of crustal material.
