	abstract = {Trends in bird population sizes are an important indicator in nature conservation but measuring such sizes is a very difficult, labour intensive process. Enormous progress in audio signal processing and pattern recognition in recent years makes it possible to incorporate automated methods into the detection of bird vocalisations. These methods can be employed to support the census of population sizes. We report about a study testing the feasibility of bird monitoring supported by automatic bird song detection. In particular, we describe novel algorithms for the detection of the vocalisations of two endangered bird species and show how these can be used in automatic habitat mapping. These methods are based on detecting temporal patterns in a given frequency band typical for the species. Special effort is put into the suppression of the noise present in real-world audio scenes. Our results show that even in real-world recording conditions high recognition rates with a tolerable rate of false positive detections are possible.},

The results of this long-term inventory are summarized and discussed. The wetland moth community was analysed for species richness and population dynamics (temporal variability of abundance were measured by a coefficient of variation - CV) and evaluated against select ecological parameters. Moth population variability (year to year fluctuation), which is highly species-specific, is a result of complex interactions between bionomic strategies (correlates of \&\#8220;r-K continuum\&\#8221;) and habitat characteristics. High bioindicator and conservation values are characteristic of moths with low values of coefficient of variation associated with vegetation units close to edaphic \&\#8220;climax\&\#8221; in the alder carr wetland. The local and regional dynamics of all moth populations associated with the natural wetland (alder carr) were investigated, and the data obtained are critical for predicting patterns of biodiversity.},

	abstract = {Without robust and unbiased systems for monitoring, changes in natural systems will remain enigmatic for policy makers, leaving them without a clear idea of the consequences of any environmental policies they might adopt. Generally, biodiversity-monitoring activities are not integrated or evaluated across any large geographic region. The EuMon project conducted the first large-scale evaluation of monitoring practices in Europe through an on-line questionnaire and is reporting on the results of this survey. In September 2007 the EuMon project had documented 395 monitoring schemes for species, which represents a total annual cost of about 20AC4 million, involving more than 46,000 persons devoting over 148,000 person-days/year to biodiversity-monitoring activities. Here we focused on the analysis of variations of monitoring practices across a set of taxonomic groups (birds, amphibians and reptiles, mammals, butterflies, plants, and other insects) and across 5 European countries (France, Germany, Hungary, Lithuania, and Poland). Our results suggest that the overall sampling effort of a scheme is linked with the proportion of volunteers involved in that scheme. Because precision is a function of the number of monitored sites and the number of sites is maximized by volunteer involvement, our results do not support the common belief that volunteer-based schemes are too noisy to be informative. Just the opposite, we believe volunteer-based schemes provide relatively reliable data, with state-of-the-art survey designs or data-analysis methods, and consequently can yield unbiased results. Quality of data collected by volunteers is more likely determined by survey design, analytical methodology, and communication skills within the schemes rather than by volunteer involvement per se. Sin sistemas de monitoreo robustos y objetivos, los cambios en los sistemas naturales seguir{\'a}n siendo un enigma para los pol\'{\i}ticos, ya que no tendr{\'a}n una idea clara de las consecuencias de las pol\'{\i}ticas ambientales que puedan adoptar. Generalmente, las actividades de monitoreo de la biodiversidad no est{\'a}n integradas o evaluadas en ninguna regi{\'o}n geogr{\'a}fica extensa. El proyecto EuMon llev{\'o} a cabo la primera evaluaci{\'o}n a gran escala de las pr{\'a}cticas de monitoreo en Europa por medio de un cuestionario en l\'{\i}nea y presenta los resultados de este muestreo. En septiembre 2007, el proyecto EuMon hab\'{\i}a documentado 395 esquemas de monitoreo de especies, lo que representa un costo anual total de casi 20AC4 millones, y la participaci{\'o}n de m{\'a}s de 46,000 personas que dedican m{\'a}s de 148,000 personas d\'{\i}as/a{\~n}o en actividades de monitoreo de la biodiversidad. Aqu\'{\i}, nos centramos en el an{\'a}lisis de variaciones en las pr{\'a}cticas de monitoreo de un conjunto de grupos taxon{\'o}micos (aves, anfibios y reptiles, mam\'{\i}feros, mariposas, plantas y otros insectos) en cinco pa\'{\i}ses europeos (Francia, Alemania, Hungr\'{\i}a, Lituania y Polonia). Nuestros resultados sugieren que el esfuerzo de muestreo total de un esquema est{\'a} vinculado con la proporci{\'o}n de voluntarios que participan en el ese esquema. Debido a que la precisi{\'o}n es una funci{\'o}n del n{\'u}mero de sitios monitoreados y el n{\'u}mero de sitios es maximizado por la participaci{\'o}n de voluntarios, nuestros resultados no soportan la creencia popular de que los esquemas basados en voluntarios tienen demasiado ruido para ser informativos. Al contrario, consideramos que los esquemas basados en voluntarios proporcionan datos confiables, con dise{\~n}os de muestreo o m{\'e}todos de an{\'a}lisis de datos de vanguardia, y consecuentemente pueden proporcionar resultados objetivos. La calidad de los datos recolectados por voluntarios probablemente est{\'a} determinada por el dise{\~n}o del muestreo, la metodolog\'{\i}a anal\'{\i}tica y las habilidades de comunicaci{\'o}n de los esquemas y no por la participaci{\'o}n de voluntarios per se.},

Composite event detection must be driven not just by the time of occurrence of an event, but also by its location of occurrence; composite event detection, as applied in traditional distributed event-based systems, needs to be reassessed. In this paper, we motivate the need to support spatio-temporal relations between composite events in mobile systems and introduce SpaTeC , a composite event language that enables simultaneous matching of event occurrences over space and time. Composite event operators provide for coarse spatio-temporal reasoning. Spatial and temporal restrictions constrain composite event detection in space and time and provide a basis for event filtering and spatio-temporal routing. Time and location stamps use a guaranteed bounds model for location estimation and time synchronization. The semantics of SpaTeC event operators is defined within this framework.},
