Available insect prey in bark patches selected by the Three-toed Woodpecker Picoides tridactylus prior to reproduction
(Suomen lintutieteellinen yhdistys, 1999)The diet composition of the Three-toed Woodpecker (Picoides tridactylus) before the onset of egg laying was investigated in eastern Finland. This was carried out in 1997 and 1998 by collecting bark samples from woodpecker ...article

Insect prey population changes in habitats with declining vs. stable Three-toed Woodpecker Picoides tridactylus populations
(Suomen lintutieteellinen yhdistys, 2003)The effect of food supply on the Three-toed Woodpecker Picoides tridactylus breeding density and productivity was investigated by comparing the pattern of annual changes in prey abundance in habitats with declining vs. ...article

Reproductive decisions of boreal three-toed woodpeckers (Picoides tridactylus) in a warming world: from local responses to global population dynamics
(Finnish Zoological and Botanical Publishing Board, 2006)Here, I examine whether both nestling prey abundance and profitability affect the timing of reproduction and hence the number of fledglings of three-toed woodpeck-ers, Picoides tridactylus. Individuals living ...article

Summer bird survey along the southern shoreline of the Kola Peninsula, between Varzuga and Pulonga
(Societas pro Fauna et Flora Fennica, 2006)We present summer bird observations from thesouthern shoreline of the Kola Peninsulain Russia, one of the last wilderness areas of the Palearctic region from which very littlebiological data are available. Bird specieswere ...article

The Relevance of Measurement Data in Environmental Ontology Learning
(Springer Nature, 2011)Ontology has become increasingly important to software systems. The aim of ontology learning is to ease one of the major problems in ontology engineering, i.e. the cost of ontology construction. Much of the effort within ...

Soil drought increases atmospheric fine particle capture efficiency of Norway spruce
(Finnish Environment Institute, 2012)Atmospheric fine particles from natural and anthropogenic sources reduce air quality and thus cause undesirable health and climate effects. Trees can act as obstacles to dispersal of particle pollution and thus remove a ...info:eu-repo/semantics/article

Making Sense of Sensor Data Using Ontology: A Discussion for Residential Building Monitoring
(Springer Nature, 2012)We illustrate the application of automated representation of knowledge acquired from sensor network data to quality of life services. Specifically, for a sensor network used to monitor a residential building we acquire ...

Acquisition and Representation of Knowledge for Atmospheric New Particle Formation
(Springer Nature, 2013)Sensors are used in environmental science to monitor an increasingly large multitude of properties of real world phenomena. An important scientific aim of such monitoring is more accurate and more complete understanding ...

Effects of species-specific leaf characteristics and reduced water availability on fine particle capture efficiency of trees
(© Elsevier BV, 2013)Trees can improve air quality by capturing particles in their foliage. We determined the particle capture efficiencies of coniferous Pinus sylvestris and three broadleaved species: Betula pendula, Betula pubescens and Tilia ...info:eu-repo/semantics/article

Representing Situational Knowledge Acquired from Sensor Data for Atmospheric Phenomena
(Elsevier, 2014)A recurrent problem in applications that build on environmental sensor networks is that of sensor data organization and interpretation. Organization focuses on, for instance, resolving the syntactic and semantic heterogeneity ...

Chemical composition, main sources and temporal variability of PM1 aerosols in southern African grassland
(Copernicus GmbH, 2014)Southern Africa is a significant source region of atmospheric pollution, yet long-term data on pollutant concentrations and properties from this region are rather limited. A recently established atmospheric measurement ...Tieteelliset aikakauslehtiartikkelit

Particle capture efficiency of different-aged needles of Norway spruce under moderate and severe drought
(NRC Research Press, 2014)Trees can remove particulate matter from the atmosphere, improving air quality and providing ecosystem services. Particle removal capacity is known to differ between tree species, but the influence of environmental factors ...info:eu-repo/semantics/article

Situational Knowledge Representation for Traffic Observed by a Pavement Vibration Sensor Network
(IEEE, 2014)Information systems that build on sensor networks often process data produced by measuring physical properties. These data can serve in the acquisition of knowledge for real-world situations that are of interest to information ...

Chemical characterization of biogenic secondary organic aerosol generated from plant emissions under baseline and stressed conditions: inter- and intra-species variability for six coniferous species
(Copernicus GmbH, 2015)The largest global source of secondary organic aerosol (SOA) in the atmosphere is derived from the oxidation of biogenic emissions. Plant stressors associated with a changing environment can alter both the quantity and ...info:eu-repo/semantics/article

Contribution from biogenic organic compounds to particle growth during the 2010 BEACHON-ROCS campaign in a Colorado temperate needleleaf forest
(Copernicus GmbH, 2015)New particle formation (NPF) is an important atmospheric phenomenon. During an NPF event, particles first form by nucleation and then grow further in size. The growth step is crucial because it controls the number of ...info:eu-repo/semantics/article
