Analysis of population trend in Saga pedo (Orthoptera: Tettigoniidae) on the edge of its range: more abundant or more intensively studied?

Popis výsledku v původním jazyce

In the Czech Republic, Saga pedo reaches the northern edge of its range. It occurs in the only one small area in the long term and it has never been systematically monitored there till 2006. Since the first finding in 1922, Saga pedo has been recorded only several times. Almost all findings have been published and the specimens preserved in museum collections. On the contrary, this species was recorded in many localities and its occurrence was relatively abundant during an extensive research carried outin 2005-2008. It could be possible, that its population size is increasing because of increasing frequency of findings during last decades. However, this very simplified view is biased due to unequal sampling effort during last 70 years. Therefore number of papers concerning terrestrial fauna of the Pavlovské vrchy hills was used as an index of the sampling effort.
