Landscape Boundaries: Consequences for Biotic Diversity and Ecological Flows
The emergence of panorama ecology in the course of the Eighties represents an impor tant maturation of ecological conception. as soon as enamored with the conceptual great thing about well-balanced, homogeneous ecosystems, ecologists now assert that a lot of the essence of ecological structures lies of their lumpiness. Patches with differing homes and behaviors lie strewn around the land scape, items of the advanced interactions of weather, disturbance, and biotic methods.

19). This creates some different requirements for the equipment. A number of saddle harness designs are available. The three main types are: 1. Double hip saddle type without leg belts 2. Double hip saddle with tight applications 3. Full harness where belts are designed for both hip and upper-body part The critical point in design is how convenient various types are to hang or sit in. It depends both on design and on the person using them. A double hip saddle type without leg belts is easier to climb in but tends to press legs together, put much pressure on the outer side of the hip and block blood circulation there.
8. Mobile vacuum cleaner used for seed collection. Powerful vacuum leaf collectors are becoming common in temperate Europe, America and Asia for collecting leaves and debris in gardens and parks. Vacuum collection inevitably implies accidental collection of a large amount of debris, which must be removed later. 4 Some Genetic Considerations in Connection with Seed Collection during cleaning. On the other hand, if cleaning is easy it may turn out to be a very efficient collection method. 4 Some Genetic Considerations in Connection with Seed Collection The objective of any seed collection should be to obtain seed of the best physiological and genetic quality.
Only trained staff can be expected to use safety equipment correctly and efficiently. But some farmers are amazingly good at climbing without safety equipment and may not be at any higher risk than those with equipment (Sect. 6). 6 Availability and Cost of Equipment Seed collection equipment, in particular branded equipment from authorised ‘overseas’ dealers, is considered quite costly compared with seed prices in most tropical countries. Sheets, nets, tarpaulins and funnels are quite expensive, as they must cover a large ground area during the period of seed fall and there is always a risk that unguarded laid-out equipment will be stolen, in particular if it is expensive and can be used for something else.
