說明
We recorded all species of vascular plants on 112 kurgans (burial mounds, tumuli) located in the Kherson region, southern Ukraine (46.63–47.36° N, 32.29–34.32°E; 39–96 m a.s.l.; ). We studied each kurgan at least twice during the field season to ensure completeness of the species lists. The study area belongs to the West Pontic grass (true) steppe zone, where the natural vegetation is dominated by tussock grasses, but is also relatively rich in forbs adapted to summer drought as well as spring therophytes and geophytes. Ukraine has the highest number of kurgans in Europe, with c. 150,000 (of the formerly c. 500,000 remaining, the majority having been destroyed by ploughing or archaeological excavations). Nowadays, in many regions of Ukraine, kurgans play a role of habitat islands (and one of the last enclaves) for steppe species and steppe vegetation in highly transformed, agricultural landscape. The conversion of the steppe to arable land occurred in the study area between 200 and 100 years ago (Lisetskii, 1992). In the Kherson region, steppe vegetation remained on less than 5% of the territory (Burkovskyi et al., 2013). The data collected in the study were used for modeling of vascular plant species richness in dependence of habitat island size and several environmental factors. The results indicated high impact of the size of a kurgan as well as landscape factors (like amount of the remaining habitat in a kurgan surroundings) on species richness of those habitat islands. To avoid data duplication, this dataset does not include species occurrences from 2004/2006 (https://doi.org/10.15468/x4drnu) published before.

取樣方法
In the years 2012–2016, we recorded the vascular plant flora of 86 kurgans that were in a relatively good state (i.e., they still contained at least five steppe plant species and were not flattened by illegal excavations or agricultural activities). They were selected to represent a wide range in size and degree of isolation from larger steppe areas. We visited each kurgan at least twice during a season to ensure completeness of the species lists. For the further analyses, we added published data from 26 kurgans located in the same region and studied with similar methods (Sudnik-Wójcikowska and Moysiyenko, 2006), resulting in 112 kurgans in the final dataset.
| 研究範圍 | We conducted the field sampling in the Kherson region, southern Ukraine (46.63–47.36° N, 32.29–34.32°E; 39–96 m a.s.l.). The climate is continental, with a mean annual temperature of 9–10°C and a mean annual precipitation of 415–450 mm (Fick and Hijmans, 2017). The landscapes are dominated by vast, slightly undulating plains. Loess is the most common geological surface formation, reaching a thickness of several tens of meters (Boiko, 1998). The study area belongs to the West Pontic grass (true) steppe zone (Bohn et al., 2004). The natural vegetation is dominated by tussock grasses, but is also relatively rich in forbs adapted to summer drought as well as spring therophytes and geophytes. |
