Martin KonvickaMartin Konvicka has analysed the distribution of butterflies in terms of area and altitude in 
CzechiaCzechia Konvicka, 2003 - Uphill shifts in distribution of butterflies in the Czech Repulic: effects of changing climate detected on a regional scale.
His research was based on a butterfly atlas in which the area of CzechiaCzechia was divided into 675 cells. 151,451 records in the form of sightings, data from literature references and collections were included for 161 species from the entire 20th century. Data from 624 cells after 1950 were used for the analyses.
As a result, the 
Camberwell BeautyNymphalis antiopa (Linnaeus, 1758)Mourning CloakCamberwell Beauty was one of 15 species whose distribution increased in relation to altitude above sea level in the second half of the 20th century.
Cells in which the Camberwell BeautyNymphalis antiopa (Linnaeus, 1758)Mourning CloakCamberwell Beauty was sighted or caught (624 cells = 100%):
| Period | Cells | Percent |
|---|---|---|
| 1951-1980 | 247 | 39,58% |
| 1980-1994 | 345 | 51,11% |
| 1995-2001 | 212 | 31,40% |
Average altitude in the mean value:
| Period | Altitude |
|---|---|
| 1951-1980 | 485 metres |
| 1995-2001 | 525 metres |

In absolute terms, the Camberwell BeautyNymphalis antiopa (Linnaeus, 1758)Mourning CloakCamberwell Beauty has seen a decline in populations at lower altitudes and stable populations at higher altitudes. The BrimstoneGonepteryx rhamni (Linnaeus, 1758)Common BrimstoneBrimstone and the Orange TipAnthocharis cardamines (Linnaeus, 1758)anthocharis cardamineaOrange Tip have experienced the same development.
