Conserving Natural Soundscapes

Bird Soundscape Recorder

The natural soundscape is the result of vocal activity of many organisms (vertebrates and invertebrate, terrestrial and aquatic) that use this mechanism to communicate and to adapt themselves to an unpredictable world. The soundscape is the result of the overlap of biophonies, geophonies, and anthrophonies (Fig. 8.17). Fig. 8.17 The potential trend of biophony, geophony, and anthrophony along a gradient of disturbance (after Napoletano 2008) Fig. 8.17 The potential trend of biophony, geophony,...

What Processes Create Mosaics

We have already discussed the origin and communality of mosaics. In general, a mosaic is created by the limited capacity of abiotic or biotic actors to spread everywhere. If we consider that every biological organism has a limited neighboring area in which to live and in which to influence the surroundings, we immediately understand that a mosaic is the result of such intrinsic character. Every species lives in a restricted space and this produces local heterogeneity. If we add the tendency for...

Developing the Mosaic Theory from a Plant Perspective

As often happens in the scientific realm theories are developed according to the approaches utilized. This is true in ecology in which the focal entities are plants, animals, virus, bacteria, fungi, or man. By using organisms most of our investigations are devoted to discovering the relationships between the specified entity and the environment. We have much empirical evidence about the relationship between plants and the environmental mosaic as well as between animals and their habitats. The...

Shape of Ecotones

Ecotone Ecology

The morphology of the borders is of great importance for the functioning of the ecotones and for the role that they can play in the dynamics of a mosaic. Several empirical studies have demonstrated that the more a border is convoluted, the more complex are the processes that can be observed Fig. 6.6 . Many species of animals Fig. 6.6 The border of a patch may be highly convoluted as in A or less convoluted as in B . Generally human activity tries to reduce border irregularity depressing the...
