Cím:	Conservation value of Orthoptera assemblages of a historically intensively used agricultural landscape: a case study in the Carpathian Lowland (East Hungary) / Arnóczkyné Jakab Dóra, Nagy Antal
Dátum:	2021
Megjegyzések:	The landscapes of European lowlands have been formed by agriculture in the last few thousands year, thus in these regions the main object of nature conservation is to protect the remain biodiversity of these secondary habitats. This diversity has outstanding importance not only in conservational, but also in agricultural aspect since yields depend on ecosystemservices. Ecological investigations mainly focus on the wildlife of remain natural habitats, and generally leave out of consideration the cultivated and other landscape elements covering especially larger part of the landscape. However, to understand the system functioning the investigation of these habitats (croplands, country roads and roadsides, etc.) is also necessary. The Orthoptera assemblages of intensively used agricultural landscapes were studied in surroundings of Sajószöged along the Sajó and Tisza rivers (East Hungary), to evaluate which landscape element can preserve larger diversity compared to semi-natural control sites (pastures and hayfields). During our three-year study (2018-2020) samplings were carried out with sweep net and transect count methods in 36 sites representing all habitat types relevant to orthopterans. In the mainly unknown study area occurrence of 29 Orthoptera species (11 Ensifera; 18 Caelifera) were recorded, among which Gampsocleis glabra (Her.), Acrida ungarica (Her.) and Celes variabilis (Pall.) are protected. Based on multivariate analysis 4 types of Orthoptera assemblages could be defined. The intensively used croplands (maize, sunflower and wheat fields) had a less diverse and quite different Orthoptera assemblages than the less intensively cultivated lucerne and red clover fields, non-cultivated habitats (roadsides and country roads) and seminatural sites (hayfields, pastures) had. Composition and diversity of the studied assemblages mainly depended on the intensity of habitat use and secondarily on the culture. The grass like vegetation structure of less intensive lucerne and red clover fields preserved larger part of the natural fauna. Also the crop rotation served the maintenance of higher diversity. Landscape and cultivation planning using our results can provide sustainable agriculture that can maintain more diverse wildlife containing large number of beneficial (e.g. predator, and pollinator) and vulnerable species and species rich assemblages.
