Nowadays human activity causes loss of biodiversity, mainly by simply changing diversified landscapes in to homogeneous panoramas. The loss of diversified landscapes and intense terrain cultivation (for example farming sector) happen to be causing the loss of biota. Improved production in nowadays technics of cultivation and other ways of land fostering have now improved importance of obtaining solutions keeping biological range. The largest biodiversity in scenery are in ecotones (or edge habitats), because they are mixture of (two) distinct habitats. As a result of that, it is very important to concentrate on individuals areas once practicing mother nature conservation.

Predatory parrots are important symptoms for neurological diversity because they are hunting close to ecotones and one of the greatest parts within their diet consists of small mammals. Many little mammal kinds live in ecotones. One way to find the proper size of ecotones for preserving the biodiversity in gardening landscapes is to study predator-prey relations. Through this study we would like to find out which in turn species precisely are living in ecotones and exactly how far that they distribute in agricultural landscapes. Also, we would like to study how long predator chickens are (mainly lesser discovered eagles Clanga pomarina) going while hunting in these landscapes. You want to give practical suggestions how wide ought to edges maintain agricultural panoramas so the biodiversity could be preserved.

Main text

Edge effect arises when two different refuge meet and interact. There exists higher biodiversity due to combination of (two) different habitats ” fauna and flora are from equally habitats. Ecotones can be quite similar, for example , when coniferous forest is following to a deciduous forest or perhaps ecotones may be with “sharp” transition, for instance, grassland is usually next into a lake or perhaps next into a crop field, lumbering pace is following to a forest etc . (Butet et al. 2006, Masing 1992).

The range of edge effect is considered to be approximately 200 metres from border to the “neighbor” biotope, but it absolutely differs between different sets of organisms (Hunter Schmiegelow 2011, Paton 1994). For example , intended for birds it truly is considered to be 50-100(200) meters from your edge (Paton 1994), but also for plants it truly is 10-30 meters (Wilcove ou al. 1986).

Environment fragmentation can be described as phenomena the moment habitat is usually divided into a number of smaller spots (Fahrig 2003, Gillespie 2012, Wilcox Murphy 1985, White 2013). As a result, there is an increase of small habitat spots and decrease from the total area of the habitat. Small habitat sections will be more vulnerable to extreme conditions (van Apeldoorn et al. 1992, Butet Leroux 2001, Haapakoski Ylönen 2010, Hunter Schmiegelow 2011).

While edge g?te are important, there is certainly lack of details about conservation and management of edge g?te in Estonia. For instance, Estonian Rural Creation Plan (ERDP) for 2014″2020 mentions the importance of edges of areas (mostly importance of keeping “lines” of woods and bushes). Yet, there are no quantitative recommendations for protecting grassland “lines” (Eesti Maaelu Arengukava 2014).

Tiny mammals live in forests, open areas and between those demeure ” in ecotones. Forest species is good for example Red-backed vole Myodes glareolus (Kozakiewicz et ing. 1999, MacDonald Barrett 2002, Marsh et al. 2001), open environment species happen to be for instance Field vole Microtus agrestis and European (or Common) pinus radiata vole Microtus subterraneus. The Eurasian pygmy Shrew Sorex minutes hails from edge demeure and grasslands (Butet ainsi que al. 2006, Korpimäki 1984). Yellow-necked mouse Apodemus flavicollis lives typically in forest areas that happen to be close to ends (Kozakiewicz ainsi que al. 1999, MacDonald Barrett 2002, Marsh et approach. 2001).

Small mammals have essential roles in ecosystem. They may be important component in foodstuff chain. Small mammals take the second and third place in trophic level. They feast upon plants and invertebrates. While eating various areas of plants (mostly seeds) little mammals are helping crops to propagate (MacDonald Barrett 2002, Masing 1992).

Small mammals are food for many predators. For example for a lot of mammals: Crimson fox Vulpes vulpes, Western badger meles, European pine marten martes, European polecat Mustela putorius and Stoat Mustela erminea. Small mammals are also food for several parrots, for instance, the Common kestrel Falco tinnunculus, the Rough-legged buzzard Buteo lagopus, the Long-eared owl Asio otus and the Common buzzard Buteo buteo. Several predators which quest small mammals are both living or hunting in edge g?te.
