Description
Summary:The three authors summarise the results of the collections effectuated in the last 36 years along the Körös/Cri? and Berettyó/Barcáu rivers. Gy. Kovács who deceased in 1996 is considered honorary author considering his initiatory attitude and his results. The Körös/Cri? rivers after the flow meeting of the Fehér-Körös/Crijul Alb and Fekete-Körös/Cri$ul Negru are forming the Kettős-Körös river. After the inflow of the Sebes-Körös/Cri$ul Repede is named Hármas-Körös. The Berettyó river is flows in the Sebes Körös/Crij. The rivers Berettyó, the Fekete and Fehér Körös spring from Romania. From the Körös/Cri? rivers, divided into six units there were accounted 55 species. The species set of the sole-standing units is influenced by the scarce exploration (in the case of Berettyó and the Hármas-Körös), and the pollution of waters (Sebes-Körös). Other influencing factors are the high percentage of the agricultural territories, the low degree of the forests (5,4%), the high degree of the daily and annually oscillation of the temperature, the soil-water rich in sodium-bicarbonate - helping the soil-sodification. As a consequence of the enumerating, the percentage of the continental fauna-circles is high, especially those of the holarctic fauna-circles, marking cultural influences. For the explored territory the most characteristic are the dacico-podolical Hygromira kovácsi and Chilostoma banalica, immigrated from the catchment area.
