Oil-Soaked Birds Saved: Hsus Participates In Historic Bird Rescue Apr 1978

Oil-Soaked Birds Saved: Hsus Participates In Historic Bird Rescue

Close Up Reports

As the world watched the black tide of crude oil from the Amoco Cadiz devastate bird life along the French coast, HSUS staffer Guy Hodge was reporting to Congress about efforts to save oil-soaked birds in a recent Chesapeake Bay oil spill. A barge (ATC- 133) carrying nearly 500,000 gallons of crude had run aground south of the Maryland-Virginia border. Some of its cargo spilled into this North American waterfowl wintering area.

Together with HSUS cruelty investigator Phil Steward, Hodge had assisted in the most successful on-site bird rescue operation in history. One out of every three rescued birds was …

Plant Dioecy, Ecology, Evolution And Sex Reversal, D. Carl Freeman Aug 1977

Plant Dioecy, Ecology, Evolution And Sex Reversal, D. Carl Freeman

Theses and Dissertations

The distribution of dioecious species among forty-four plant communities of western United States was examined. The dioecious habit is most prevalent in harsh environments. In many communities, over 20 percent of the species and 40 percent of the individuals are dioecious. Dioecy is most common among woody species which are pollinated by wind. It is concluded that inbreeding depression alone is insufficient to account for all known facts concerning dioecy. Disruptive selection acting upon differential success of gametes produced on sites of differing quality appears to have played a major role in producing separate sexed individuals. Dioecious species reported to …


Mammalian Dispersal And The Ontogeny Of Individual Behavioral Phenotypes, Marc Bekoff Jul 1977

Mammalian Dispersal And The Ontogeny Of Individual Behavioral Phenotypes, Marc Bekoff

Ethology Collection

Explanations of dispersal mechanisms in mammals that have stressed the importance of aggression by dominant (?) individuals as the immediate cause of the dispersal of less aggressive (more subordinate?) individuals are insufficient for explaining recent data collected on a variety of mammals. In fact, avoidance of social interaction at the time of dispersal is more characteristic of some species in which individuals emigrate. Studies that have investigated genetic correlates of dispersal in rodent populations that undergo regular cycles are few and have not provided any "causative" explanations. In various canids and rodents, behavioral interactions at the time of dispersal do …

Struggle To Save Dolphins Continuing Jun 1977

Struggle To Save Dolphins Continuing

Close Up Reports

The Humane Society of the United States has initiated a nationwide boycott of a tuna products until real progress is made in reducing the needless slaughter of porpoises in tuna nets.

In the Spring of 1976, HSUS first asked its members to refrain from buying tuna because of the high porpoise mortality and the tuna industry's unwillingness to adopt any research porpoise-saving procedures. Recently, HSUS Program Coordinator Patricia Forkan called for a nationwide boycott of tuna.

Live Trap Preference Among Grassland Mammals, Robert K. Rose, Norman A. Slade, James H. Honacki Jan 1977

Live Trap Preference Among Grassland Mammals, Robert K. Rose, Norman A. Slade, James H. Honacki

Biological Sciences Faculty Publications

In two independent studies, small mammals of grassland communities in eastern Kansas, when given a choice, preferred Fitch to Sherman live traps. Except for the harvest mice in the demographic study, the type of preferred trap and magnitude of selection was remarkably comparable, with microtines showing slight, and cricetines strong, preferences overall. The merits of each type of trap are compared, and related to season, weather, prior experience, and trap-associated mortality.

The Ecology Of The Dominant Tick Species In The Northwestern Portion Of The Dismal Swamp National Wildlife Refuge, Mary Keith Garrett Apr 1974

The Ecology Of The Dominant Tick Species In The Northwestern Portion Of The Dismal Swamp National Wildlife Refuge, Mary Keith Garrett

Biological Sciences Theses & Dissertations

Elements of the ecology of the two dominant man-biting ticks were studied during 1971-1973 in two locations in Southeastern Virginia, namely, what is now the Dismal Swamp National Wildlife Refuge and Newport News City Park. Tick species composition, relative abundance, density, and distribution in the two areas were compared. In addition, the Dismal Swamp locality was used as a test area for studies on the survival of native, lab reared and translocated Dermacentor variabilis (Say) and Amblvomma americanum (L.) in relation to selected abiotic factors. The Newport News locality served as a control area for these studies.

Relative Efficiency Of Roots And Tops Of Plants In Protecting . The Soil From Erosion, Joseph Kramer, J. E. Weaver Jan 1936

Relative Efficiency Of Roots And Tops Of Plants In Protecting . The Soil From Erosion, Joseph Kramer, J. E. Weaver

Papers of John E. Weaver (1884–1956)

An increasing realization of the importance of preventing or controlling soil erosion has resulted in numerous scientific investigations. Some of these are concerned with soil characteristics which promote or retard erosivity (Middleton, '30; Middleton et al., '34; Lutz, '34; and Bouyoucos, '35). Many have to do with engineering methods of reducing soil wastage (Bates and Zeasman, '30; Ramser, '30; Roe, '33; and Bartel, '35). But perhaps most were planned to discover the effects of plants in protecting and binding the soil, reducing runoff, and consequent loss of soil and subsoil (Sampson and Weyl, '18; Duley and Miller, '23; Lowdermilk, …


Ecological Relations In The Pitch Pine Plains Of Southern New Jersey, Harold J. Lutz Jan 1934

Ecological Relations In The Pitch Pine Plains Of Southern New Jersey, Harold J. Lutz

Yale School of the Environment Bulletin Series

An investigation was undertaken with the primary object of determining the factors responsible for the peculiar development of the vegetation in the Plains community. The conclusion ·is reached that the Plains areas are capable of supporting forest growth similar to that in the Pine Barrens. Inasmuch as the Plains owe their continued existence to repeated fires, it is obvious that effective fire protection is the first and most important step toward their rehabilitation.


Trends And Silvicultural Significance Of Upland Forest Successions In Southern New England, Harold J. Lutz Jan 1928

Trends And Silvicultural Significance Of Upland Forest Successions In Southern New England, Harold J. Lutz

Yale School of the Environment Bulletin Series

The problems encountered in the silvicultural treatment of southern New England forests are many. They result largely from the extremely diverse and complex conditions under which the forest is developed. Due to the glaciated nature of the region the soil character changes radically within relatively short distances. With changes in soil from place to place come minor changes of forest composition. One of the chief reasons for the problems which the silviculturalist encounters in this region is the large number of species which make up the stands. There are approximately thirty commercially important forest trees in southern New England. The …
