Introduction
Professor in Ecology at the University of Lodz, Poland, specialized in Urban Ecology, Conservation Biology, Grassland Ecology, Insect cology and University Pedagogy. My empirical research focuses on plant-insect assemblages of meadow habitats; I am most familiar with carabid beetles, though I also work with wild bees, butterflies and other taxa. I am an active member of the Eurasian Dry Grassland Group EDGG and the Urban Europe Research Alliance UERA.

In this study, we investigate the changes in both vascular plant and carabid beetle assemblages in response to reducing the intensity of management of park lawns in the city of Helsinki. Three levels of mowing were applied to patches of previously managed park lawns: (1) intensively mown, (2) mown until the previous season and unmanaged since, and...

Full-text available
This article provides a perspective on nature-based solutions. First, the argument is developed that nature-based solutions integrate social and ecological systems. Then, theoretical considerations relating to relational values, multifunctionality, transdisciplinarity, and polycentric governance are briefly outlined. Finally, a conceptual model of...

Blue infrastructure is an important component of urban green infrastructure, due to its capacity for water cycle regulation and soil formation, as well as supporting unique biodiversity. Urban ponds, as part of urban blue, can harbour a diverse assemblage of aquatic macroinvertebrates. As yet, it is not clear how urbanisation affects macroinvertebr...
Article
Full-text available
Grassland ecosystems of Europe comprise a variety of mostly semi-natural habitats, which have developed over long periods of traditional land-use regimes, such as grazing and mowing, and they support a remarkable level of biodiversity. At some scales, the species diversity of these habitats is greater than that of tropical rain forests. Such valuab...

This report summarises the activities and achievements of the Eurasian Dry Grassland Group (EDGG) from January 2018 through July 2019. During the reported period, two Eurasian Grassland Conference (EGCs) took place: the 15th EGC in Sulmona, Italy, and the 16th EGC in Graz, Austria. The 11 th and 12 th EDGG Field Workshops studied vegetation diversi...
Article
Most investigations of human impacts on biodiversity have been conducted within 1–3 years post-disturbance, although many biological responses develop over a longer period of time and annual community variation cannot be fully controlled. We therefore conducted a follow-up of carabid beetles over ten years in Norway spruce (Picea abies) dominated f...

Article
Full-text available
Disturbance by biomass removal is a crucial mechanism maintaining the diversity of Palaearctic grasslands, which are unique biodiversity hotspots. The century-long traditional land use of mowing, grazing and burning, has been fundamentally changed in many parts of the Palaearctic. Due to socio-economic changes, large areas of former pastures and me...

Full-text available
This review considers factors affecting the flight capacity of carabid beetles and the implications of flight for carabids. Studies from the Dutch polders in particular show that young populations of carabids consist predominantly of macropterous species and macropterous individuals of wing-dimorphic species. Also populations of wing-dimorphic cara...

Palaearctic grasslands encompass a diverse variety of habitats, many of high nature value and vulnerability. The main challenges are climate-change, land-use change, agricultural intensification and abandonment. Many measures are in place to address these challenges, through restoration and appropriate management, though more work is necessary. We...

Helsinki is located on a peninsula projecting into the Baltic Sea from the south coast of Finland. The country lies in the Boreal region, which is typified by the mixed coniferous forests, although Helsinki itself is located in a narrow strip of the hemiboreal zone, which also has noble deciduous forest, similar to those of the temperate region. Th...

Most semi-natural open habitats in Europe have been traditionally maintained by anthropogenic activities, such as grazing or mowing, preventing the establishment of woody vegetation. These habitats harbour a remarkably rich biodiversity in terms of both plant and animal species, but are also highly threatened mainly by agricultural intensification...

Full-text available
The Eurasian Dry Grassland Group (EDGG) was founded in 2008 (then named European Dry Grassland Group) as network of researchers and conservationists dealing with natural and semi-natural grasslands in the Palaearctic (Europe, North Asia, North Africa). The basic aims of the EDGG are: ► to compile and to distribute information on research and conser...

Thesis
Full-text available
In this thesis I use carabid beetles (Coleoptera, Carabidae) and vascular plants to investigate the ecological effects of urbanization on forested and dry meadow habitats in the city of Helsinki, Finland. I also investigate factors that affect species diversity and the occurrence of rare and sensitive species in particular, in order to draft recomm...
Article
Insect and plant assemblages of dry meadow habitats have declined dramatically since the late 19th century due to changes in grassland management practices and the resultant overgrowth of these with nitrophilic vegetation in Finland. The Municipality of Helsinki is committed to developing strategies for the maintenance of urban biodiversity, and ne...

Full-text available
Carabid beetles, bees, butterflies and a small number of other beetle taxa were sampled during excursions to sites in the Prespa region, Greece, during the Ninth European Dry Grasslands Meeting. Sampling was mainly by hand-searching and netting, and also a small number of pitfall traps. A considerable number of carabid beetles were caught and that...

'Carabidologists do it all' (Niemelä 1996a) is a phrase with which most European carabidologists are familiar. Indeed, during the last half a century, professional and amateur entomologists have contributed enormously to our understanding of the basic biology of carabid beetles. The success of the field is in no small part due to regular European C...

Urban regions often contain remnants of ecologically valuable habitats. Whilst meadow habitats have been recognized as ecologically important and much studied, little attention has been given to meadow assemblages of urban locations. We studied the effects of meadow type, urbanization level, and management on vascular plant species richness, field...

Golf is a popular sport, with increasingly large areas of urban and peri-urban land being designated for golf course development. Yet, more than half of the land area of a typical golf course is considered rough and out-of-play areas that can, if managed appropriately, provide habitats for wildlife. Using pitfall traps, 6944 carabid beetles belongi...

Europe is a highly urbanised continent. The consequent loss and degradation of urban and peri-urban green space could adversely affect ecosystems as well as human health and well-being. The aim of this paper is to formulate a conceptual framework of associations between urban green space, and ecosystem and human health. Through an interdisciplinary...

A disturbance gradient comprising three intensities of management of grasslands in urban parks is used to study the responses of carabid beetles to disturbance. The three levels of disturbance are: mown, intermediate and meadow. GLM is used to analyze the response of two morphological traits to disturbance: body size, macroptery and wing length of...

Carabid abundance, species richness and diversity were compared along an urban-rural gradient in Helsinki, Finland. Increased urbanization was found to result in significant reductions in species richness, though the reductions in abundance and diversity were not statistically significant. Forest habitat-specialist species were scarce in rural site...

We studied communities of carabid beetles in residual forest patchesalong urban-suburban-rural gradients in three cities (Helsinki, Finland; Sofia,Bulgaria and Edmonton, Canada) to examine their responses to urbanisation. OnlyFinnish carabids showed a marked division of community structure along thegradient. In Bulgaria and Canada, carabids did not...
