Article
The anthropogenic impact on the functioning of natural systems and the concept of Anthropocene as a period of the human domination of the Earth has been widely discussed in literature in the past few decades. Consequently, several land systems classifications have been developed on a global scale to capture the diversity, intensity, and spatial dis...
Article
Variation in bird community composition across habitats may be reflected by changes in species’ ecological characteristics. By their comparison between habitats, we can learn information about the factors underlying these changes. With this purpose, we used data from a nation-wide breeding bird monitoring scheme surveying birds in 15 habitat types...

The development of sustainable transport is a key challenge in societies where there is an accelerated need for socio-economic development. This is the case for seven countries from central and south-eastern Europe that share the Carpathian Mountains. The challenge of developing sustainable transport requires transdisciplinary, or at least cross-se...
Article
Full-text available
Human activities have shaped the environment since long before the advent of agriculture and resulted in anthropogenic landscapes, which are sometimes perceived as natural, but are clearly shaped by dozens of previous generations. This study is the first to apply ecological niche modelling on a long time-series of archaeological data to illuminate...

The Virunga Massif mountain gorilla population has been periodically monitored since the early 1970s, with gradually increasing effort. The population declined drastically in the 1970s, but the numbers stabilized in the 1980s. Since then, the population has been steadily increasing within their limited habitat fragment that is surrounded by a dense...

Species distribution models are a useful tool applied in many branches of biology, especially when dealing with threatened organisms. In combination with GIS techniques, these models are especially important and valuable for predicting occurrence of rare species, for example, orchids. Orchids are an endangered plant group, protected in the whole wo...

The paper deals with the current spatio-temporal distribution of tourism in the Krkonoše Mts and its spatial environmental impacts. At present, the high intensity of tourism and the use of the Krkonoše Mts landscape for the needs of tourism are understood as the most signifi cant problems of the Krkonoše Mts. One of the main goals of the study is t...

The Czech rural landscape is a subject of research because it is affected by both intensification and extensification of land cover. This landscape was influenced in recent decades by political and socio-economic changes; we studied how these changes were reflected in the land cover development in protected areas. We selected ten Protected landscap...

Green infrastructure is a strategically planned network that broadens traditional biodiversity conservation methods to also encompass the concept of ecosystem services (ES). This study aims to identify the network of green infrastructure in Central Europe. An analysis of ecological connectivity is based on ES supply quantified for CORINE land cover...

Conservation efforts have led to the recovery of the endangered mountain gorilla populations. Due to their limited potential for spatial expansion, population densities increased, which may alter the epidemiology of infectious diseases. Recently, clinical gastrointestinal illnesses linked to helminth infections have been recorded in both gorilla po...

The border region between Austria, the Czech Republic, and Germany harbors the most south‐western occurrence of moose in continental Europe. The population originated in Poland, where moose survived, immigrated from former Soviet Union or were reintroduced after the Second World War expanded west‐ and southwards. In recent years, the distribution o...

This article presents preliminary results of the project on monitoring of landscape changes of the large-scale protected areas in the Czechia. Here, we focused on increasing human impact in the areas, especially on urban and recreational structures. We prepared data describing development of landscape from 1950s till recent. Topographic maps and ae...
Article

One of the main questions in ecology and conservation is how organisms are governed and affected by their traits within the context of abiotic gradients. The main question of our study addresses how patch, topography, and land use influence conservation trait status (rarity and red-list index) of birds generally, and of farmland and woodland specia...

Spatial planning is the most important tool for balancing the needs of the society, economy and the environment. Spatial planning differs from one country to another due to the different conditions and historical background, but there are major similar characteristics. In the first phase of the project, we elaborated a comparison analysis about t...

Article
Surveying mammals is always a challenge for field biologists. When those mammals are nocturnal and mostly arboreal, as in the case of the dormice (Gliridae), the task proves even more difficult. During the summers of 2015 and 2016 we carried out a national survey of edible dormouse (Glis glis) distribution in the Czech Republic. Twenty-one trained...
Article
The impact of Pleistocene climatic oscillations on tropical biomes is associated with changes in the extent of forest cover. Fruit bats have played a role in woodland dynamics via pollination and seed dispersal. We hypothesized that phylogeographic patterns of Rousettus on continental Africa and adjacent islands should show a signature of pluvial‐d...
Article
Ash dieback, caused by the ascomycete fungus Hymenoscyphus fraxineus, has been rapidly expanding across Europe during the last two decades, posing a considerable threat to native ash populations. In this study, we applied regression-based models trained by field data, in conjunction with geographic information systems, to produce spatial prediction...

Land cover data: Aerial imagery was used. Images were taken in the summer season of each year (2006-2012); therefore the imagery for a particular year shows the conditions of second half of previous year and first half of year, when images were taken. Imagery has a pixel resolution of 20cm. Land cover was categorized into fourteen types. Mountain f...
Article
Population fragmentation represents a leitmotif of conservation biology, but the impact of population reconnection is less well studied. The recent recolonization of large carnivores in Europe is a good model for studying this phenomenon. We aim to show novel data regarding distribution and population genetic structure of the grey wolf in Central E...

Understanding the ecological, behavioral and evolutionary response of organisms to changing environments is of primary importance in a human-altered world. It is crucial to elucidate how human activities alter gene flow and what are the consequences for the genetic structure of a species. We studied two lineages of the Egyptian fruit bat (Rousettus...

Central European landscape has undergone dramatic changes during the last decades. Big changes in the political and economic systems resulted in a large-scale transformation in land use, especially in the agricultural and silvicultural sectors. At the same time, significant changes in urban regions were recorded. In order to quantify and compare th...

Phytophthora alni is an invasive organism that causes root and collar rot in alders, which significantly damages the forest and riparian vegetation of alder trees in Central and Western Europe. In the Czech Republic, this pathogen was first confirmed in 2001, and since then it has been gradually spreading from the west to the east. Here, we applied...

Recent climate changes are most likely the major determining factor for the increasing importance of Central Europe for wintering waterbirds, given that most of the region is located on the edge of these species’ wintering ranges. A few recent large-scale studies have demonstrated changes in species distribution at the flyway level, but detailed st...

Landscape typologies are widely recognised as useful tools for landscape management and planning. However, there is wide range of different approaches producing diverse outputs, which makes the usage of landscape typologies sometimes difficult or confusing in general practice (Wascher ed., 2005). The same situation is found in the Czech Republic, w...
