Added: October 31, 2008Estimating the forces and loads applied in tree systems requires the weight of different parts and portions be determined. One of the most difficult measures to estimate is green xylem weight in branches. Wood weight can be precisely and accurately determined in the laboratory from small samples at oven-dry moisture contents. Within living trees, moisture content values are difficult to determine accurately. The moisture contents of living tree xylem and associated tissue can vary between 30% and 250% as compared with the weight of any associatedwoody material.
- Housing Crocodilians in Captivity: Considerations for Central America and Caribbean
-
Attempts to develop and successfully operate facilities that commercially exploit crocodilians have always faced considerable challenges, especially in developing countries. However, there are guidelines that, if implemented, can increase chance of success and reduce crocodilian mortality. Combining captive breeding with ranching and tourism may be the best overall approach for linking conservation of crocodiles with economic benefits to local communities and governments. Crocodilian enclosures require careful planning and consideration of the aims of the facility. All enclosures must share similar minimal requirements of providing safe and secure confinement in a manner that also provides for the health and well being of crocodiles. The overall success of any facility holding crocodilians relies upon reducing amount of stress to individuals by providing and maintaining high water quality, adequate temperatures, appropriate cover, and a high standard of food quality and hygiene.
