Studies examining these effects simultaneously are rare. Here we explore the direct top-down and direct and indirect bottom-up forces regulating the abundance and predation success of an intermediate predator, the web- building spider Argiope bruennichi (Araneae: Araneidae). We manipulated plant diversity (2, 6, 12 or 20 sown species) in 9 wildflower strips in a region of intensive farmland. To identify the major factors regulating the distribution and abundance of A. bruennichi, we quantified three characteristics of vegetation (species diversity, composition and vegetation structure) as well as the spider’s prey community and natural enemies. The distribution and abundance of A. bruennichi was regulated by combined bottom-up and top-down processes as well as by direct and indirect interactions between trophic levels. Four main factors were identified: (1) the strong direct effect of vegetation structure, (2) the positive effect of plant species diversity, which affected spider abundance directly and indirectly through increased densities and size of flower-visiting prey species, (3) the positive or negative direct effects of different plant species, and (4) the strongly negative direct effect of predacious hornets. The advantage of taking a global approach to understand the regulation of species abundance is highlighted first by the quantification of the relative importance of factors, with a surprisingly strong effect of hornet predators, and second by the discovery of a direct effect of plant diversity, which raises intriguing questions about habitat selection by this spider."],["dc.identifier.doi","10.1016/j.baae.2012.10.001"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61917"],["dc.language.iso","en"],["dc.relation.issn","1439-1791"],["dc.title","Direct and indirect bottom-up and top-down forces shape the abundance of the orb-web spider Argiope bruennichi"],["dc.type","journal_article"],["dc.type.internalPublication","no"],["dspace.entity.type","Publication"]]

The discrepancy may arise due to a limited or closed local species pool in experiments, while natural systems in meta-community contexts experience dynamic processes, i.e., colonization and extinctions. In our study, we analysed plant community properties and above-ground biomass within a semi-natural (i.e., not weeded) experiment in an agricultural landscape. Eleven replicates with four different diversity levels were created from a species pool of 20 wildflower species. We found an overall significant negative relationship between total diversity and productivity. This relationship likely resulted from invasion resistance: in plots sown with low species numbers, we observed colonization by low-performing species; colonization increased species richness but did not contribute substantially to productivity. Interestingly, when analysing the biomass of the sown and the colonizer species separately, we observed in both cases positive BEF relationships, while this relationship was negative for the whole system. A structural equation modelling approach revealed that higher biomass of the sown species was linked to higher species richness, while the positive BEF relationship of the colonizers was indirect and constrained by the sown species biomass. Our results suggest that, in semi-natural conditions common in extensive agroecosystems, the negative BEF relationship results from the interplay between local dominant species and colonization from the regional species pool by subordinate species."],["dc.identifier.doi","10.1007/s00442-018-4305-1"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61915"],["dc.language.iso","en"],["dc.relation.issn","0029-8549"],["dc.relation.issn","1432-1939"],["dc.title","Understanding negative biodiversity–ecosystem functioning relationship in semi-natural wildflower strips"],["dc.type","journal_article"],["dc.type.internalPublication","no"],["dspace.entity.type","Publication"]]

However, the microphones themselves received little attention so far, and specifications that determine the recordings’ sound quality are seldom mentioned. Here, we demonstrate the importance of microphone signal-to-noise ratio for sampling sonant animals.\r\nMethods\r\n\r\nWe tested 12 different microphone models in the field and measured their signal-to-noise ratios and detection ranges. We also measured the vocalisation activity of birds and bats that they recorded, the bird species richness, the bat call types richness, as well as the performance of automated detection of bird and bat calls. We tested the relationship of each one of these measures with signal-to-noise ratio in statistical models.\r\nResults\r\n\r\nMicrophone signal-to-noise ratio positively affects the sound detection space areas, which increased by a factor of 1.7 for audible sound, and 10 for ultrasound, from the lowest to the highest signal-to-noise ratio microphone. Consequently, the sampled vocalisation activity increased by a factor of 1.6 for birds, and 9.7 for bats. Correspondingly, the species pool of birds and bats could not be completely detected by the microphones with lower signal-to-noise ratio. The performance of automated detection of bird and bat calls, as measured by its precision and recall, increased significantly with microphone signal-to-noise ratio.\r\nDiscussion\r\n\r\nMicrophone signal-to-noise ratio is a crucial characteristic of a sound recording system, positively affecting the acoustic sampling performance of birds and bats.

Which kinds of information sources are important to professionals and which do they use in their every-day work? Answering these questions and knowing more about the information sources used by conservation professionals would promote effective knowledge transfer from science to practice. We conducted a survey to identify the information sources used by Swiss professionals in nature conservation, including the forest sector. Experience-based information sources (e.g. personal experience, direct exchange with colleagues and experts) are more important for professionals in nature conservation than evidence-based sources (e.g. various print products such as guidelines, specialized journals in national languages, text books targeted to professionals). They were also more often used. Articles from international scientific journals are hardly ever consulted by conservation professionals. It is thus important that scientists engage as experts and take time for direct personal contact and exchange with conservation professionals (e.g. by offering field trips). Given that professionals have little time in their daily business for searching and implementing new scientific knowledge and results, short, audience-targeted and synthetizing publications in national languages as well as specialized websites should be provided by researchers.
