Effects Of Oviposition On Remating., Response To Pheromones., And Longevity In The Female Caribbean Fruit Fly., Anastrepha Suspensa (Diptera: Tephritidae), J. Sivinski, R. R. Heath

Entomology Papers from Other Sources

Female Caribbean fruit flies with oviposition opportunities remate frequently, two-thirds of them after 1 wk and approximately one-third every subsequent week. Those with limited chances to oviposit remate less frequently, and about half of them mate only once during their lifetime. Ovipositing females regain receptivity to male-produced pheromones within a week, unlike nonlaying females. Mortality rates also are higher for egglaying females.

Ecology, Behavior, And Distribution Of Blattella Asahinai (Orthoptera: Blattellidae) In Central Florida, Richard J. Brenner, R. S. Patterson, P. G. Koehler

Entomology Papers from Other Sources

The Asian cockroach, Blattella asahinai Mizukubo, a close relative of the German cockroach, B. germanica (L.), has been discovered in over 900 km² from Tampa to Lakeland, Fla., and is prevalent in citrus groves, wooded areas, lawns, and homes. Differentiation of the two species is best accomplished by the diagnostic behavior of the Asian cockroach-it is crepuscular (sunset) and nocturnal, readily flies, is attracted at sunset to light-colored or brightly lit surfaces, and lives outdoors in large numbers. Analyses of microhabitat composition of 86 trap sites indicate that the principal habitat of the Asian cockroach is leaf litter in …

Quantitative Analysis Of Temperature., Moisture., And Diet Factors Affecting Insect Development, David W. Hagstrum, George A. Milliken

Entomology Papers from Other Sources

Extensive published data on the developmental times of nine species of stored-product Coleoptera in relation to temperature, moisture, and diet were described by regression equations. At most temperatures, the order of relative influence of these factors on development was temperature > moisture > diet. However, moisture and diet influenced larval development more than temperature near the optimal temperature for development of each species. Egg, larval, and pupal stage durations at 27°C averaged 15, 66, and 19% of the total developmental time, respectively, at moistures above 12%, and 12, 72, and 15% of total developmental time at moistures below 12%. Similar percentages were …

Insect Succession In A Stored-Corn Ecosystem In Southeast Georgia, R. T. Arbogast, M. A. Mullen

Entomology Papers from Other Sources

Insect populations infesting a small bulk of corn stored in southeastern Georgia were followed for 8 yr by monthly sampling beginning 8 mo after the corn was placed in storage. The species composition of the insect community changed as the corn deteriorated. Nine species became dominant at some stage of succession. Sitotroga cerealella (Olivier) was the dominant species when the first sample was taken. It was succeeded a month later by Oryzaephilus surinamensis (L.), which declined rapidly after 2 mo of dominance and died out during the third year. Cryptolestes ferrugineus (Stephens) was dominant at various times during the first …

Research By Bureaucracy: Hattie Plum Williams And The National Commission On Law Observance And Enforcement, 1929-1931, Michael R. Hill

Department of Sociology: Faculty Publications

This paper explores the bureaucratized research activities (1929-1931) of the National Commission on Law Observance and Enforcement (NCLOE) from the perspective of Hattie Plum Williams' sociobiographical experience. Williams was a doctoral student of George E. Howard and earned her Ph.D. in 1915 -- the ftrst doctorate in sociology awarded by the University of Nebraska. That same year, she joined the Nebraska faculty and eventually became Chair of the Department (1922-1928).2 In 1931, at age 53, this full professor was called upon be an unpaid fieldworker, gathering data according to rigid protocols stipulated by the NCLOE. Archival reconstruction of Williams' "view …

The Vascular Flora And Plant Communities Of Seward County, Nebraska, Steven B. Rolfsmeier

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A recent botanical survey of Seward County in southeastern Nebraska recognizes ten representative plant communities including four major vegetation zones (tall-grass prairie, eastern deciduous forest, floodplain woodland and lowland [floodplain] prairie), and a total of 599 species of vascular plants representing 324 genera in 95 families. Three hundred seventy-five species were not previously reported for the county. Although the study area includes an interesting topographic and perhaps physiographic boundary formed by the terminal moraine of the Kansan glaciation, no evidence supporting an analogous floristic boundary was found.

Interpreting Modern And Paleo-Environments By Analysis Of Water-Stress In Xylem: Examples From Nebraska And Arkansas, James Landon

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Wood-anatomical responses to an environmental gradient were studied in trees of northwestern and southeastern Nebraska and northwestern Arkansas to determine between- and within-site variation and differential sensitivity of diverse anatomical patterns. These data were then used as a tool to try to reconstruct paleo-environments, using wood-fossil assemblages from the Crookston Bridge Member of the Valentine Formation. No significant within-site variation was found in living trees, but great differences in environmental sensitivity were detected among the anatomical types. Responses displayed by the fossils do not match those of my modern study areas.

Use Of Drc 1339 To Control Crows In Three Roosts In Kentucky And Arkansas, Frank L. Boyd, Douglas I. Hall

Eastern Wildlife Damage Control Conference: 3rd (1987)

Field tests utilizing DRC 1339 (3- chloro-4-methylbenzamine hydrochloride) 98% concentrate on whole kernel corn for crow (Corvus brachyrhynchos) control were conducted in January and February 1981 in Lexington and Louisville, Kentucky, and in 1982 in Ashdown, Arkansas. Treated bait was placed in staging areas near the roosts after pre-baiting indicated good acceptance at the sites. The rate of acceptance varied with bait placement. Best results were obtained when bait was placed on bare ground at habitually used staging areas close to the roost site. Population reductions of up to 25% were obtained with limited baiting. DRC 1339 appears …

Diving Birds Of North America: Species Accounts — Grebes (Podicipedidae), Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

Grebes are small to medium-sized diving birds having bills that vary from short and rather blunt tipped to long and acutely pointed, with bare lores and head feathers not extending to the linear or oval nostrils. There are 11 functional primaries and 17–22 secondaries, the inner secondaries longer than the primaries. Molting of the primaries is simultaneous; the wings are not used for underwater propulsion, which is provided by the feet. The rectrices are soft, rudimentary, and hidden. The body feathers are small, water-resistant, and shiny. Aftershafts and adult down feathers are present. The legs are set extremely far back …

Small Mammals: Pests Or Vital Components Of The Ecosystem, Carolyn Hull Sieg

Great Plains Wildlife Damage Control Workshop Proceedings

Small mammals regarded as "pests" should not be viewed separately from other components in the ecosystem. Small mammals have significant influences on vegetation and soils, exert predatory pressure on other animals, and provide food for predators. Future management efforts should include consideration of these diverse influences.

Management Of Prairie Dog Populations In Wind Cave National Park, Richard W. Klukas

Great Plains Wildlife Damage Control Workshop Proceedings

Since the late 1920's there have been periodic control programs on black-tailed prairie dogs in Wind Cave National Park. The most recent control effort, which began in 1982, resulted in the reduction of total dogtown acreage from 2,000 to 750 acres. Recent studies carried out within the park have provided managers with more soundly based justification for carrying out control programs. The same information also points to the importance of maintaining prairie dog populations at or above certain minimum levels and the need for integrating this control program with several of the other resource management programs being carried out in …

Bioconcentration Of Heavy Metals (Cu, Cr, Pb, And Zn) In The Missouri River Near Sioux City, Iowa, Robert Conklin, Suzie Galles, Edward Shane, Rod Tondreau

United States Army Corps of Engineers, Omaha District

The concentrations of the heavy metals- copper, chromium, lead, zinc- in the biota of the Missouri River were measured at a control site upstream of Sioux City and at a site downstream of the city. Bioconcentration factors for each of the metals were calculated for fish, periphyton, and invertebrates, and the concentrations of metals in the river sediments were measured.

Concentrations of the same metals were measured in the sediment, water, periphyton, invertebrates, zooplankton, and fish of Snyder's Bend Lake. Bioconcentration factors were calculated for each of the biological communities and were found to be very similar to those found …

Biological Features Of Saline Wetlands In Lancaster County, Nebraska, James E. Ducey

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The natural history of saline wetland areas near Lincoln, Lancaster County, was evaluated. Most remaining salt marshes occur on saline soils along Little Salt Creek. Numerous plant species of saline soils occur that are limited to this part of the State. The avifauna is diverse, with 67 species recorded during the breeding season, 47 of them breeding. Because wetlands are limited in distribution in Nebraska, key biological elements, potential threats to the areas, and management considerations are discussed.

The Characteristics And Phytogeographic Affinities Of The Flora Of Nine-Mile Prairie, A Western Tall-Grass Prairie In Nebraska, Robert B. Kaul, Steven B. Rolfsmeier

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Three hundred ninety-two species, subspecies, and varieties have been recorded at Nine-Mile Prairie, a relict tall-grass prairie that has been reduced from 323 to 97 ha in the past 50 years. There are 218 native and 17 introduced herbaceous perennial species, and 73 native and 24 introduced annuals. Analogous numbers for biennials are 15 and 11, for shrubs are 14 and one, for trees are ten and three, and for woody vines are six and none. One hundred twenty-one native species are of central and eastern North American phytogeographic affinity, and 109 are of transcontinental affinity. Seventy-nine of the Prairie's …

Proximity Nesting: The Great Horned Owl And Red-Tailed Hawk, Steve Shupe

Nebraska Bird Review

Introduction: Forty-two nests of the Great Horned Owl (Bubo virginianus) and 78 nests of the Red-tailed Hawk (Buteo jamaieensis) were surveyed during a three-year ecological study (1982–84). In 11 instances nests of the two species overlapped the hunting areas of the other. Home ranges, in which most hunting takes place, have been defined by various authors (Miller, 1930; Baumgartner, 1939; Hagar, 1967). For this study Hawks and Owls nesting within one-half mile of each other were compared. The proximity nesting of these two species seemed likely to increase the possibility of predation upon the young of …

A North Florida Ant Fauna (Hymenoptera: Formicidae), Clifford Johnson

Insecta Mundi

This paper updates and summarizes the ant fauna of Alachua County, Florida, with two basic objectives. The first objective is presentation of a current, documented check-list consistent with existing taxonomy and an insight on species groups where taxonomic changes are likely in subsequent revisions. The second objection objective seeks to identify changes in the fauna since Van Pelt’s pioneer survey of 1948, and provide a basis for similar comparisons in the future.

The county consists of 902 square miles in north-central Florida and embraces essentially all inland habitats of the northern peninsula. This rich habitat variability is reflected in its …

Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Abstract: Two hundred nine white-tailed deer (Odocoileus virginianus) were radiotracked in the central Superior National Forest, Minnesota, from 1973 through winter 1983-84; 85 deaths were recorded. Annual survival was 0.31 for fawns (<1.0 years old), 0.80 for yearling (1.0-2.0 years old) females, 0.41 for yearling males, 0.79 for adult (≥2.0 years old) females, and 0.47 for adult males. Monthly survival rates were high from May through December (0.94-1.00), except for yearling (0.60) and adult (0.69) bucks during the November hunting season. Most mortality occurred from January through April when gray wolf (Canis lupus) predation was an important mortality source for all cohorts. Yearlings males were most vulnerable to hunting and adult males to wolf predation.

Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Abstract: Survival of 203 yearling and adult white-tailed deer (Odocoileus virginianus) was monitored for 23,441 deer days from January through April 1975-85 in northeastern Minnesota. Gray wolf (Canis lupus)predation was the primary mortality cause, and from year to year during this period, the mean predation rate ranged from 0.00 to 0.29. The sum of weekly snow depths/month explained 51% of the variation in annual wolf predation rate, with the highest predation during the deepest snow.

United States Fish and Wildlife Service: Publications

We studied the food habits of midcontinent sandhill cranes (Grus canadensis) during spring 1978 and 1979 at their primary staging area along the Platte River and compared population food and foraging habitat requirements with availability. Crane diets varied among the 3 principal foraging habitats, but not between sexes, ages, or years. Cranes feeding in cornfields ate >99% corn (total dry wt); those feeding in native grasslands and alfalfa fields consumed 79-99% invertebrates. The composite diet of cranes was 97% corn and 3% invertebrates, including 2% earthworms, 0.5% snails, and 0.5% insects. Presumably, corn provided energy, whereas invertebrates from grasslands and …

Histoplasmosis And Its Impact On Blackbird/Starling Roost Management, A.R. Stickley Jr., R.J. Weeks

Eastern Wildlife Damage Control Conference: 2nd (1985)

Histoplasmosis is a common and sometimes serious fungal disease that primarily affects the lungs, but can also involve other parts of the human body. The disease is characterized by 3 major forms: acute pulmonary, chronic cavitary, and disseminated histoplasmos is. Two fungicides are effective in treatment of the disease, but serious side effects often result. The occurrence of the fungus, Histoplasma capsulatum, is associated with large quantities of bird and bat excreta that have come in contact with soil. Roost sites must generally be occupied by birds for at least 3 years before soil conditions are conducive to its …

Dispersing Blackbird-Starling Roosts With Helium-Filled Balloons, Donald F. Mott

Eastern Wildlife Damage Control Conference: 2nd (1985)

Large (120 cm diameter) helium-filled balloons (2-10 per ha of roost) tethered about 8 m above the vegetation were effective in dispersing blackbirds and starlings from roosting sites. Bird population estimates before, during, and after balloon exposure showed that the balloons frightened the birds and caused most of them to abandon the roost. Roosting bird numbers at each of 5 test roost sites (0.3 to 1.7 ha) were reduced an average of 82% (min-max 47-100%) during 3 to 4 evenings of balloon exposure. Winds >16 km/h during the study made it difficult to keep the balloons aloft and not entangled …

Fat Deposition And Usage By Arctic-Nesting Sandhill Cranes During Spring, Gary Krapu, George Iverson, Kenneth Reinecke, Cheryl Boise

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Body weight, fat, and protein levels of arctic-nesting Sandhill Cranes (Grus canadensis) were measured at several locations during spring migration and on the breeding grounds. Body weights of adult males and females increased by about 34%( 1,129 g) and 30% (953 g) from early March at the Platte River to late April at Last Mountain Lake, Saskatchewan; average fat content increased from about 250 to 990 g. Rates of weight gain and fat deposition among males and females averaged 25-18 and 16-13 g/day. Body weights and fat content of cranes staging along the North Platte River followed similar …
