Pair Formation By Color-Marked Whooping Cranes On The Wintering Grounds, Thomas V. Stehn

Proceedings of the North American Crane Workshop

Observations were made of color-marked whooping cranes (Grus americana) at Aransas during the 1977-94 winters. Suhadult cranes wintered near their juvenile home ranges in flocks averaging 3.12 birds. One and 2 winters prior to nesting, subadults at Aransas tended to form duos apart from other subadults. Frequencies of association 1 year prior to nesting averaged 65.4%. However, 27.7 % of pair bonds (n = 18) formed during spring migration or on the breeding grounds without any observed prior association at Aransas. Sixty-eight banded cranes formed pairs. Pair members averaged 1.06 years difference in age. Winter territories of adults …

Food And Energy Intake Rates Of Wintering Whooping Cranes Foraging On Two Selected Food Items, Felipe Chavez-Ramirez, Jay T. Nelson, R. Douglas Slack

Proceedings of the North American Crane Workshop

Number, mass, and potential energy of food items consumed by wintering whooping cranes (Grus americana) foraging on blue crab (Callinectes sapidus) and woltberry (Lycium carolinianum) fruit were estimated and compared between 2 consecutive winter periods. Mass consumed was determined through field observations by quantifying the number of items taken per unit time and the average, or modal, weight of each food item determined from collections. Gross energy intake was determined by calculating the product of mass consumed times gross energy (kJ/g) of each food item. Potential energy retained was calculated by determining metabolizable energy …

Semen Collection And Fertility In Naturally Fertile Sandhill Cranes, Guojun Chen, George F. Gee, Jane M. Nicolich, Joanna A. Taylor

Proceedings of the North American Crane Workshop

Aviculturists often ask if semen collection will interfere with fertility in naturally fertile pairs of cranes. We used 12 naturally fertile Florida sandhill crane (Grus canadensis pratensis) pairs for this study, 6 control and 6 experimental. All pairs had produced fertile eggs in previous years and were in out-of-doors pens scattered throughout different pen complexes, within auditory range but physically isolated. Semen was collected on Tuesday mornings and Friday afternoons from 26 February 1993 to 4 June 1993. We used standard artificial insemination methods to collect and to evaluate the semen and spermatozoa. Semen collection did not affect semen quality …

Results Of Eight Years Of Predator Control To Enhance Sandhill Crane Production On Malheur National Wildlife Refuge, Oregon, Gary L. Ivey

Proceedings of the North American Crane Workshop

Because of a 21 % decline in breeding pairs of greater sandhill cranes (Grus canadensis tabida) on Malheur National Wildlife Refuge from 1971 to 1985, a predator control program was initiated in 1986 to enhance production. The primary cause for the decline was low recruitment of young due to high predation by ravens (Corvus corax). raccoons (Procyon lotor), and coyotes (Canis latrans), On average, predators destroyed 46% of all crane nests and 90% of the prefledged colts. Mink (Mustela vison) were added to the program in 1993 after a study …

Long Bone Fracture Management In A Sandhill Crane: A Case Report, Patrice N. Klein, Dorothy Thompson

Proceedings of the North American Crane Workshop

A 65-day-old, juvenile Mississippi sandhill crane (Grus canadensis pulla) sustained an oblique fracture of the right middiaphyseal femur. Internal fixation by use of an intramedullary pin and full cerclage wire was performed to stabilize the fracture site. Post-operative medical management of these fractures is often unsuccessful due to secondary complications associated with long-term restraint. This report describes the successful recovery of an endangered sandhill crane with a long bone fracture of the pelvic limb through a program of incremental physical therapy beginning 2 weeks post-femoral fracture repair. Sling support, assisted walking, and hydrotherapy were methods effective in preventing …

Características De La Osificación Craneal En Phyllomedusa Boliviana (Anura: Hylidae), Rafael O. De Sá, E. O. Lavilla

Biology Faculty Publications

RESUMEN. Dentro de la familia Hylidae disponemos de información sobre las secuencias de osificación craneal para menos del 4.0% de sus miembros. El presente trabajo describe la secuencia de osificación craneal de Phyllomedusa boliviana. El patrón general de osificación es similar a lo reportado para otras especies de la familia, pero existen algunas diferencias importantes tales como la osificación tardía de los próoticos y la osificación premetamórfica de neopalatino, vómer, cuadrado-yugal, pterigoides y columela. El lento desarrollo ulterior de la osificación resulta en juveniles con cráneos extensamente cartilaginosos.

Physical Condition And Reproductive Success Of White-Tailed Deer At Fort Chaffee, Ar: A Five-Year Study, Donald A. Phillips

Masters Theses

A baseline study conducted in 1991 demonstrated that the resident white-tailed deer (Odocoileus virginianus) population at Fort Chaffee, Arkansas was in poor condition, with below average reproductive success, body weight, and antler size, and above average parasite load compared to other regional deer populations. Consequently, a management program was initiated in 1991 which included: (1) neutralizing acidic soils, (2) prescribed burning, (3) planting supplemental food plots, and (4) liberalizing the harvest of female adults from the population. The purpose of this study was to monitor changes in the health and reproductive success of the herd as this program was implemented. …

Herrnkind, Michael J. Childress, Rodney Bertelsen, William Sharp, Thomas Matthews, Jennifer M. Field, Harold G. Marshall

Biological Sciences Faculty Publications

Florida Bay, the shallow lagoon separating mainland Florida and the Florida Keys, USA, is experiencing an unprecedented series of ecological disturbances. In 1991, following reports of other ecosystem perturbations, we observed widespread and persistent blooms of cyanobacteria that coincided with the decimation of sponge communities over hundreds of square kilometers. Juvenile Caribbean spiny lobsters Panulirus argus, among other animals, rely on sponges for shelter; the impact of sponge loss on the abundance of lobsters and their use of shelter, in particular, has been dramatic. The loss of sponges on 27 experimental sites in hard bottom habitat in central Florida Bay …

A Review Of Ministerial Policy Guidelines For Rock Lobster Processing In Western Australia From The Working Group Appointed By The Minister For Fisheries And Chaired By Peter Rich, Peter Rich

The Distribution Of Rice Rats (Oryzomys Palustris) And Meadow Voles (Microtus Pennsylvanicus) In Tidal Marsh Communities On The Eastern Shore Of Virginia, Allison L. Sowell

Biological Sciences Theses & Dissertations

Two tidal marsh sites were selected for live trapping of small mammals on the Eastern Shore of Virginia. Trap grids were established at site and animals were trapped and tagged each month for one year. Habitat variables were measured at the peak of the growing season and again in late winter when vegetation was at its least luxuriant. ANOVA and multiple regressions were used to analyze the relationships between rice rats and meadow voles and associated variables related to habitat structure.

ANOVA revealed where rice rats and meadow voles differed in habitat preferences. Meadow voles were consistently captured in association …

The Impact Of The New Management Package On Smaller Operators In The Western Rock Lobster Fishery, Ross Gould

Fisheries Management Papers

For the 1993/94 western rock lobster fishing season several new management strategies were introduced. The objective of the changes to the management package was to protect the rock lobster fishery. It was also to provide sufficient breeding stock to ensure viability of the industry. The most significant new measure was a temporary (two seasons) 18 percent pot reduction. Other changes were also made. There were considered sound reasons for reviewing and changing the previous management package. Despite this, some fishermen were critical of the new management package, and claimed that it unfairly disadvantaged smaller operators. Against this background, the Department …
