Understanding Behavioral Responses of Wildlife to Traffic to Improve Mitigation Planning

Creating and maintaining sustainable transportation systems depends in part on understanding and mitigating ecological impacts. Wildlife crossing structures (WCS) are often used to mitigate impacts on wildlife populations. WCS and existing structures may provide passage for multiple species, depending on their sensitivity to traffic disturbance and perception of the roadway. In a previous project, the research team found that traffic conditions and traffic noise could reduce WCS effectiveness in facilitating passage of diverse and sensitive species. In the current project, they expanded the geographic scope to 26 sites throughout California, including detailed measurements of vehicle noise and lighting impacts on wildlife use of structures. They investigated individual animal behavior as the animals approached structures as a possible mechanism for reducing species diversity due to traffic disturbance. In order to inform future WCS planning, placement and construction, the team studied traffic noise and light impacts on wildlife in the vicinity of the proposed Liberty Canyon wildlife over-crossing (over US 101), the first and largest of its kind in California. They improved a preliminary statistical model of the effects of traffic on WCS use of existing structures. The authors recommend strategies for transportation agencies to use in developing and modifying WCS to improve wildlife passage.View the NCST Project Webpag

Just Serve Yourself...

Party meals may be as formal or informal as the hostess desires. The type of meal wished and the kind of party given will determine its method of serving. The informal service, however, is very popular because of the friendly atmosphere. The informal service is best put into use through serving the meal as a buffet luncheon or supper. This form of service is especially appropriate for a large number of guests or when the number of people to be served is more than can be accommodated by the dining room table

Lemon or Cream?...

The story is told that more than 250 years ago a dreamy-eyed Dutchman living in China made a discovery. He found that by adding a little hot water to a curious leaf, he had a most interesting drink. He went to England, taking the leaf with him, but the English would have nothing to do with him and his queer hot drink

Simple Table Service for the Home

We are living in a time of high pressure, and many things that help make life more livable are apt to be crowded out The dining table is the center of the social life of the home. Because of our high pressure living and the many different interests each member of the family has, the only time when all can be at home is at dinner

Luncheon, Shamrock-Trimmed...

In searching for the origin of St. Patrick\u27s Day we find that St. Patrick, patron saint of Ireland, was not Irish himself, as many suppose. In the book, Customs of Mankind, by Lilliam Eichler, we find that his birthplace is somewhat obscure. The French claim him, the Scotch and the Welsh claim him, but his true birthplace is not known

The Road Effect Zone GIS Model

The numerous effects roads have on the surrounding environment were investigated and geographically modeled. Several of these effects were then isolated and looked at in greater detail, developing a model that represents the various interactions between a road and the surrounding region. These road effects could be expressed in a GIS (geographic information system) environment, based on user-inputs. A traffic noise model was used to estimate the extent and intensity of this road effect. Environmental attributes were also summarized within the traffic noise effect zone as an example of evaluation of road effects useful during early transportation planning. The model was designed to be a proof-of-concept of a standalone tool for environmental and transportation planners in local and state agencies

Method for delivering drugs soluble in a vaporization vehicle

This invention relates to a method for delivering drugs sublimable in a vaporization vehicle. The method involves combining a sufficient amount of a vaporization vehicle to sublime the drug and the drug to be delivered, heating the vaporization vehicle to substantially its boiling point and administering the vapor by inhalation to a subject
