AbstractThe aim of our study is to describe and visualise the spread of two non-indigenous land snail species Cepaea nemoralis and Monacha cartusiana in the Czech Republic during more than 100 years period. Several factors play an important role in changes of the distribution of these species: ecological (climate change), ethological (passive dispersal potencial) and economic (increasing traffic as a vector of spreading). The spreading of M. cartusiana has a rapidly increasing trend. More than half sites in the Czech Republic were colonised by this species in 2000–2010. While the spread of C. nemoralis has been continuous during the last century, the rapid range extension was recorded in the last two decades.

European Origin

In 2010, several new sites of the dune snail Cernuella neglecta (Draparnaud, 1805) were documented relatively far from their previously known sites in the Czech Republic. Cernuella neglecta was found at these new sites in front of villas, on dry ruderal meadows and in urban areas. The anthropic origin of those populations is probable. C. neglecta is another land snail species of southern European origin that is spreading to the new sites during last few years.

Atlantic Period

Pseudofusulus varians (C. Pfeiffer, 1828) is one of the most endangered land snail species in the Czech Republic. It is a relict species from Atlantic period of the Holocene, inhabiting exclusively nature beech and scree forests. Originally it was known from 16 sites in the Krušné Hory Mts. (Ore Mts.) (NW Bohemia, Czech Republic) and one site in the Moravskoslezské Beskydy Mts. (East Moravia, Czech Republic). The occurrence of the snail was recently confirmed only at seven sites in the Krušné Hory Mts. Remaining sites were destroyed due to human impacts, mainly acid rains and insensive forest management. Therefore its populations survived only in forest patches hidden in hardly accessible places. P. varians is strictly dendrophilous species, so the main threat is dead wood removing and clear cutting. As it is endangered in the whole Europe (Austria, Croatia, Germany, Slovakia and the others), it is very important to protect its modern sites.

A new finding of the land snail species Oxychilus alliarius was recorded in the Czech Republic. This West European species was found in the six isolated sites during the last thirteen years always in western part of Bohemia. This paper brings new information on the distribution of Oxychilus alliarius in the Czech Republic.

The aim of the presented article is to evaluate the impact of climate change on the sugar content of grapes in the Czech Republic during the period 2000–2019 through selected indicators on the basis of available secondary sources. Attention is focused on the developments in both the main wine-growing regions of Moravia and Bohemia. In the field of viticulture and wine-growing, the sugar content of grapes, as a basic parameter for the classification of wines, plays an important role. In the Czech Republic, the average sugar content of grapes has had a constantly growing trend. This trend is evident both in the wine-growing region of Bohemia and in the wine-growing region of Moravia. The impact of climate change, especially the gradual increase of average temperatures in the growing season, cannot be overlooked. It greatly affects, among other things, the sugar content of grapes. Calculations according to the Huglin Index and the Winkler Index were used to determine the relationship between climate and sugar content. These indexes summarize the course of temperatures during the entire vegetation period into a single numerical value. The results show that both indexes describe the effect of air temperature on sugar content in both wine regions of the Czech Republic in a statistically significant way. The Huglin Index shows a higher correlation rate. The Winkler Index proved to be less suitable for both areas. Alternatively, the Winkler Index calculated for a shorter growing season was tested, which showed a higher degree of correlation with sugar content, approaching the significance of the Huglin Index.

The paper is focused on assessing the development of the economic account for agriculture of the Czech Republic in the selected reference period 1998–2003. There were evaluated effects of the particular types of the economic accounts. Methods of regression and correlation analysis and development trends were used for the mathematical-statistical analysis. The plant production output similarly as the output of agricultural industry show an increasing tendency since the period under investigation reaching a peak about 2001 and in next years decreasing in difference to the gross value added at basic prices and the net value added at basic prices which shows an increasing trend throughout the period. Both animal output and the agricultural services output show a decreasing trend reaching a minimum about 2002.

Wildlife trade involves many animal and plant species and their products. CITES (Convention on International Trafe in Endangered Species of Wild Fauna and Flora) aims on protecting endangered plants and animals from being overharvested for the purposes of international trade through system of regulations, permits and monitoring. CITES Trade Database is a tool dedicated for the evidence of international trade of endangered wildlife species. We used records from the CITES Trade Database to conduct the analysis of the legal wildlife trade in the Czech Republic in the period 2008-2018. A total amount of 12,615 shipment records were extracted from CITES Trade Database. Amongst most imported taxons belong mammals (mostly genuses Ursus and Panthera) and reptiles (primarily genuses Varanus and Triocerus), while most exported taxons are birds (prevailing genuses Platycercus, Polytelis and Falco) and mammals (especially genus Lemur). While the export records showed an increasing trend, the imports were culminating around the average level of 642.3 records per year and lowest amount in the last year of the period. We emphasise smuggling of snowdrops and tigers and their products, which were reported to be seized, but with lack of records in legal trade.

AbstractClimate change affects the distribution of many species, including Burgundy and Périgord truffles in central and southern Europe, respectively. The cultivation potential of these high-prized cash crops under future warming, however, remains highly uncertain. Here we perform a literature review to define the ecological requirements for the growth of both truffle species. This information is used to develop niche models, and to estimate their cultivation potential in the Czech Republic under current (2020) and future (2050) climate conditions. The Burgundy truffle is already highly suitable for cultivation on ~ 14% of agricultural land in the Czech Republic (8486 km2), whereas only ~ 8% of the warmest part of southern Moravia are currently characterised by a low suitability for Périgord truffles (6418 km2). Though rising temperatures under RCP8.5 will reduce the highly suitable cultivation areas by 7%, the 250 km2 (3%) expansion under low-emission scenarios will stimulate Burgundy truffles to benefit from future warming. Doubling the moderate and expanding the highly suitable land by 352 km2 in 2050, the overall cultivation potential for Périgord truffles will rise substantially. Our findings suggest that Burgundy and Périgord truffles could become important high-value crops for many regions in central Europe with alkaline soils. Although associated with uncertainty, long-term investments in truffle cultivation could generate a wide range of ecological and economic benefits.
