, . In course of time he joined the Bristol Medical School, ?lng most of his clinical work at the Royal Infirmary, and 0 taming the diplomas of M.R.C.S., L.R.C.P. in 1891. For a short time he was engaged in private practice, and as Medical Officer to the Bristol Foresters for two years. He acted as assistant medical officer in mental hospitals at ^ster and Maidstone, at which institutions he la...

Woody growth is evolutionarily ancient, yet has been gained and lost multiple times in plant evolution and is readily enhanced or minimized in eudicot speciation. New molecular genetic and genomic studies in Populus and Arabidopsis that are defining the genes responsible for cambium function and woody growth suggest that the genes regulating woody growth are not unique to woody plants. Surprisi...

The distribution and dynamics of natural-mediated zoonosis (Lyme disease) in the Carpathian region have been studied measures for its prevention developed. It is established that vectors Lyme disease are Ixodes mites. transmitted transmissible through adhesion mites to human body. In mites, transovarian (through eggs) transphase larvae nymphs) transmission pathogens.
 data obtained indicat...

The efficiency of a tree improvement program can be greatly affected by the degree of seed efficiency in the nursery. The gains from tree improvement can be 50% greater from a nursery with 90% seed efficiency than from a nursery with 60% seed efficiency. However, because the nursery and tree improvement are usually operated by different divisions, the goals of the nursery manager may not includ...

Systemic acquired resistance (SAR) is the phenomenon whereby a plant’s own defense mechanisms are induced by prior treatment with either a biological or chemical agent. The concept of SAR has been widely recognized and studied for the past 100 years in relation to increasing resistance to fungal, bacterial, and viral pathogens of economically important crop plants. The use of SAR as part of a d...

The goal of this study was to use LiDAR data to assess damage to trees from a December, 2007 ice storm affecting the city of Norman, Oklahoma (USA). Preand post-storm LiDAR data was collected for the city and it was processed and analyzed in a GIS platform. Results indicate that for single standing trees, LiDAR data can accurately assess and quantify damage with an accuracy of 90%. However, it ...

Woodland caribou (Rangifer tarandus caribou) are sensitive to changes in understory vegetation resulting from forest harvesting and are, therefore, of special concern for foresters and habitat biologists. Effective management of this species requires reliable habitat inventories which, because of the large heterogeneous areas over which caribou range, can be costly. We used Landsat Thematic Map...

Concern regarding extensive damage to tropical forests resulting from logging increased dramatically after World War II when mechanized logging systems developed in industrialized countries were deployed in the tropics. As a consequence, tropical foresters began developing logging procedures that were more environmentally benign, and by the 1990s, these practices began to be described as “reduc...

The National Cancer Register maintained by the Office of Population Censuses and Surveys (OPCS) was used to investigate the relative risks of soft tissue sarcomas among farmers, agricultural workers, and related occupational groups. The relative risk for the group as a whole was 1.15 (95% confidence limits 0.83-1.59). One of the four subgroups (which comprises farmers, farm managers, and market...

The adaptive capacity of forests and foresters to overcome the adverse effects climate change remains highly uncertain despite intense research efforts. While are often invited “not put all their eggs in one basket,” adaptation strategies mostly depend on silvicultural diversification. To explore how socioeconomic tools can complement these technical evolutions forestry, we designed an interdis...
