UsingPlantago lanceolataas a model species, we investigated whether introduced populations show significant differences from native populations in several growth and chemical defense traits.Plantago lanceolata(ribwort plantain) is an herbaceous plant species native to Europe and Western Asia that has been introduced to numerous countries worldwide. We sampled seeds from nine native and ten introduced populations that covered a broad geographic and environmental range and performed a common garden experiment in a greenhouse, in which we infested half of the plants in each population with caterpillars of the generalist herbivoreSpodoptera littoralis. We then measured size-related and resource-allocation traits as well as the levels of constitutive and induced chemical defense compounds in roots and shoots ofP. lanceolata...

This trend is particularly strong in some of the most biodiverse regions of the continent, such as Central and Eastern Europe. Intensive grazing is known to decrease species diversity and alter the composition of plant and insect communities. Comparatively little is known, however, about how intensive grazing influences plant functional traits related to pollination and the structure of plant-pollinator interactions. In traditional hay meadows and intensive pastures in Central Europe, we contrasted the taxonomic and functional group diversity and composition, the structure of plant-pollinator interactions and the roles of individual species in networks. We found mostly lower taxonomic and functional diversity of plants and insects in intensive pastures, as well as strong compositional differences among the two grassland managem...

To assess the importance of different drivers, baseline information is needed on interaction networks and plant reproductive success around the world. We conducted a systematic literature review to determine the state of our knowledge on plant-pollinator interactions and the ecosystem services they provide for European ecosystems. We focussed on studies that published information on plant-pollinator networks, as a community-level assessment of plant-pollinator interactions and pollen limitation, which assesses the degree to which plant reproduction is limited by pollinator services. We found that the majority of our knowledge comes from Western Europe, and thus there is a need for baseline assessments in the traditional landscapes of Eastern Europe. To address this data gap, we quantified plant-pollinator interactions and conducted breeding system and pollen supplementation experiments in a traditionally managed mountain meadow in the Western Romanian Carpathians. We found the Romanian meadow to be highly diverse, with a healthy plant-pollinator network. Despite the presence of many pollinator-dependent plant species, there was no evidence of pollen limitation. Our study is the first to provide baseline information for a healthy meadow at the community level on both plant-pollinator interactions and their relationship with ecosystem function (e.g. plant reproduction) in an Eastern European country. Alongside the baseline data, we also provide † Considered dual first authors.

Dabei wird der Fokus auf drei Handlungsfelder gelegt: Die Starkung etablierter Strukturen, die Neuschaffung von Rahmenbedingungen und die weitere Integration von Cititzen Science in bestehende Konzepte durch verschiedene Masnahmen. Auserdem werden im Grunbuch vor allem auch die Ziele und Moglichkeiten ebenso wie eine Vision fur die Rolle von Citizen Science im Jahr 2020, unter anderem in Form von zehn Leitbildern, definiert. Im Vordergrund stehen auch hier die breite Etablierung, Anerkennung und Einbeziehung von Citizen Science in gesellschaftsrelevante Kontexte.

Sie bilden die naturlichen Vegetationseinheiten an den Fluslaufen und ihren Uberschwemmungsbereichen. Auwalder sind in der Vergangenheit grosflachig durch menschliche Aktivitaten beeinflust, verandert und zerstort worden. Der heutige Bestand an Auwaldern bedarf einer europaweiten Strategie zum Schutz und zur zukunftigen Entwicklung (Gerken 1988). Die Degradation von Auwaldflachen hat viele Ursachen und ist ein Zusammenspiel von verschiedensten Faktoren. Obwohl Auenstandorte durch ihre okologischen Bedingungen in den Uberschwemmungsbereichen von Flussen eine landwirtschaftliche Nutzung erschwerten, wurde von den Menschen schon fruhzeitig versucht, die hohe Fruchtbarkeit des angeschwemmten nahrstoffreichen Bodenmaterials fur Viehweiden und Ackerbau zu nutzen. Auch die Wasserkraft der die Auwalder durchziehenden Flusse wurde in vielfaltiger Weise genutzt, wie z.B. fur Muhlen und zur Holztrift (Arnhold 1964). Der Ausbau der Flusse fur Schiffahrt und Energiewirtschaft und die Anlage von Staudammen hatte weitere schwerwiegende Eingriffe in die Auenokosysteme zur Folge. Erst durch Masnahmen zur Hochwasserfreilegung und Flusregulierung wurde eine grosflachige Umnutzung von Auwaldern fur Vieh- und Ackerwirtschaft sowie fur Siedlungsprojekte und Baumasnahmen ermoglicht. Aus diesem Grund sind an vielen Flussen die Auwalder bis auf wenige linienhafte, flusbegleitende Strukturen beseitigt worden.

Developing this evidence relies-in practice-on long-term engagement of volunteers who observe and record species over large spatial and temporal scales. Many biodiversity monitoring schemes, including those for insects, are highly dependent on conservation-based citizen science programs with a long-term continuity. As these schemes are built entirely on good will, the nature of social relations and networks is pivotal to success. We assess the working mechanism of a monitoring scheme that is citizen-based as a case study. The German Butterfly Monitoring Scheme (hereafter TMD for "Tagfalter-Monitoring Deutschland") operates, as many other citizen science monitoring schemes, through an overarching national network of regional subnetworks of volunteers and a central scientific coordination. Using a questionnaire survey paired with a visual social network assessment, we investigate how participants interact within these networks and assess their motivations to engage. We characterise the functionality of this social network based on mechanism of coordination and participation, flows of information and knowledge exchange among recorders, regional and central coordinators, academic scientists and institutions. By analyzing the interactions, we show how the social network facilitates and ensures various communication modes and thereby fosters long-term engagement, stability and growth of the scheme. We identify the central role of project coordination and the importance of social relations within citizen-based monitoring programs for engagement and personal satisfaction. Based on our empirical study, we derive a set of recommendations for establishing and maintaining successful volunteer networks in insect citizen-based monitoring programs.
