The bank vole (Myodes glareolus) is the natural host of Puumala virus (PUUV) in vast areas of Europe. PUUV is one of the hantaviruses which are transmitted to humans by infected rodents. PUUV causes a general mild form of hemorrhagic fever with renal syndrome (HFRS) called nephropathia epidemica (NE). Vector-borne and zoonotic diseases generally display clear spatial patterns due to different s...

Agricultural production and its associated land use comprise the most important key factor regarding biodiversity and environmental impact within the wider countryside in Denmark. Currently, a number of land use changes are implemented in environmental action plans, such as afforestation, restoring wetlands and protection of drinking water catchments. Growing attention is put on the potential o...

Abstract: The main purpose of this paper is introducing modelling and application as a research domain in mathematics education through reviewing related literature. The first purpose of this review is to give a more clear meaning of modelling and application, and base on that, makes the distinction between modelling in mathematics education & modelling in other scientific domains. There are so...

Prevention researchers have found that drinking in different contexts is related to different alcohol problems. Where and with whom people drink affects the types of alcohol-related problems they experience. Consequently, identifying those contexts that result in the greatest number of problems provides a novel opportunity to target new prevention efforts aimed at those contexts. However, ident...

In the preface to the this book, the authors point out that simulation models can be useful tools for investigating real phenomena in an idealized way. However, the complexity of simulation models can often deter their use by ecologists. Also, complexity and implementation details of a simulation may obscure assumptions underlying the model. These observations provide partial justification for ...

Transboundary environmental issues, like climate change, have in recent years received much attention from the side of political scientists and economists. Within the economics discipline, we witness sometimes differences between ecologically-oriented and mainstream economists, which may form a barrier for proposing clear policy recommendations on external effects in open and interacting spatia...

The number of interoperable research infrastructures has increased significantly with the growing awareness of the efforts made by the Global Earth Observation System of Systems (GEOSS). One of the societal benefit areas that is benefiting most from GEOSS is biodiversity, given the costs of monitoring the environment and managing complex information, from space observations to species records i...

Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships in other types of ecological networks, or in 2...
