Effects of habitat and landscape features on grassland Orthoptera on floodplains in the lower reaches of the Tisza River Basin

Secondary habitats are important in biodiversity conservation: a case study on orthopterans along ditch banks

“…Based on the analyses of the trait groups separately, we showed that the mobility of species has a prominent role in shaping the abundance pattern of orthopterans, and sedentary species are presumably not able to build viable populations along ditch banks. This is in accordance with numerous studies highlighting the importance of dispersal ability of orthopterans in agricultural landscapes (Dziock et al, 2011;Marini et al, 2010Marini et al, , 2012Torma and Bozsó, 2016;Poniatowski and Fartmann, 2010). In general, low mobility of insects is linked to their increased vulnerability to extinctions in a fragmented landscape since sedentary species, for instance, are less able to (re)colonize remaining suitable habitats in the unsuitable matrix (Braschler et al, 2009;Bommarco et al, 2010;Habel et al, 2016).…”

“…We distinguished Ensifera and Caelifera groups to represent the differences between them e.g. in reproductive potential and egg deposition of females (Torma and Bozsó, 2016). Based on the mean number of ovarioles (Reinhardt et al, 2005), Ensifera species are usually considered to have a high reproductive potential compared to Caelifera.…”

“…Natural and semi-natural grasslands in Europe still contain a diverse fauna and flora, but recent studies (e.g. Hernández-Manrique et al, 2012;Torma and Bozsó, 2016) conclude that existing conservation strategies based mainly on the protection of areas of high natural value may be insufficient to ensure conservation of the invertebrate species pool at landscape scale. Conservation of the invertebrate diversity thus needs a landscape perspective.…”

“…It has been shown that native biota can survive in these habitats. Such anthropogenic habitats often have a long history, facilitating development of species-rich habitats (Musters et al, 2009), and they may provide resources for populations of rare and endangered species (Torma and Bozsó, 2016). In contrast, newly established sawn grass strips and abandoned field margins are comparatively species poor and are beneficial particularly for common species (Musters et al, 2009;Ernoult et al, 2013).…”

The response of Orthoptera to grazing on flood defense embankments in Europe

“…They concluded that habitat generalism, southerly distribution and oviposition (Holst et al 1996). gary showed that insect groups respond differently to habitat and landscape characteristics and Orthoptera are generally influenced by landscape more than habitat features (Torma and Bozsó 2016). Krausz et al (1995) found that the distance between habitats was correlated with a difference in orthopteran assemblages.…”
