Download file to see previous pages In winters C. bicknelli migrates mainly to montane broadleaf forests of Dominican Republic. It has been listed as a priority species for most ornithological organisations of the locations where it is still surviving. This study aims to estimate the decline in the population of C. bicknelli during the period of 1993 to 2003.
The area selected for the study was White Mountain National Forest in north-central New Hampshire. Routes were charted to enable observation of maximum geographical area covered with coniferous forests and adjacent mixed forests, at elevations ranging from 740 to 1470m. Trained observers conducted annual point counts from June 5 to June 28, between 0500 and 1100 hrs EST; starting at one point and then using the rope to station at point two, 250m apart. Observations were taken consistently in silent period of 5 minutes for 10 days every year, excluding days with rain or wind velocity above 40km/h. Annual trend of birds spotted or heard in all routes was fitted against time, for a common set of routes and points. The count in year y (Cy), was assumed to follow the following model:
E(Cy)=A*by, where, b is the trend coefficient for the annual rate of change in population size. The model was fitted using non-linear least squares, or in other words, Poisson regression allowing for over- or under-dispersion.
The study revealed a substantial decline of the population of C. bicknelli during the study period; being maximum in small patches of Terrace Mountains and Mount Crawford while in expansive habitats of Carter Moriah Range and Presidential Range, least decline was estimated. Previous studies have revealed the eradication of C. bicknelli from several Island and coastal areas of Canada, Mount Greylock, Dixville Notch, NH and Brook Notch, ME. The population decline has also been reported from Massachusetts, New York, Vermont, New Hampshire and Maine.    ...Download file to see next pages Read More

New Population Dilemma

...Economic Pressures As China’s economy continues to grow rapidly, economic challenges arise that may challenge the country as a competitor in the global marketplace. The rapidly changing landscape, from farmland to increase desert area, puts a strain production of food sources such as grains and rice. With increased automobile usage, farmland is being paved over for roads. Less farmland for grain production is a serious problem, as China exports much of its grain.

Less grain for export will negatively impact China’s economic growth, while... Pressures...

...ROWE In the case of Rowe vs. New Hampshire Motor Transport Association, the main issue was about the sale of tobacco products to minors. In terms ofprecedent for the case, stated related cases include Morales, in which the state argument to set aside regulations is assumed to be in line with the situation where, “efforts to prevent minors from obtaining cigarettes is unpersuasive in light of other legislative alternatives available to the State.

Long Term Care Reform in New Hampshire

... Long Term Care Reform in New Hampshire    Background:  The word care means concern for another being. When we feel sympathy, empathy, affectionate or anxious towards someone it can be said that we care for that person. Care is a kind of feeling that develops within our minds for somebody intimate to us. Sometimes on the contrary we are forced to express care but that does not mean we feel the same care which we express. Giving on the other hand has different connotations. For example giving can be in the monetary terms and at the same time giving can be out of love and compassion. Giving may arise also under compulsion. Therefore we can say that giving cannot have a particular characteristic. It is multi dimensional. Taking cue...
