A Research Agenda for Environmental Management
The understanding of global environmental management problems is best achieved through transdisciplinary research lenses that combine scientific and other sector (industry, government, etc.) tools and perspectives. However, developing effective research teams that cross such boundaries is difficult. This book demonstrates the importance of transdisciplinarity, describes challenges to such teamwork, and provides solutions for overcoming these challenges. It includes case studies of transdisciplinary teamwork, showing how these solutions have helped groups to develop better understandings of environmental problems and potential responses.
Vertically Stratified Frugivore Community Composition and Interaction Frequency in a Liana Fruiting Across Forest Strata
Abstract: Vertical stratification is a key feature of tropical forests and structures plant-frugivore interactions. However, it is unclear whether vertical differences in plant-frugivore interactions are due to differences among strata in plant community composition or inherent preferences of frugivores for specific strata. To test this, we observed fruit removal of a diverse frugivore community on the liana Marcgravia longifolia in a Peruvian rain forest. Unlike most other plants, Marcgravia longifolia produces fruits across forest strata. This enabled us to study effects of vertical stratification on fruit removal without confounding effects of plant species and stratum. We found a high nu...
Networked Systems
This book constitutes the revised selected papers of the 10th International Conference on Networked Systems, NETYS 2022, held as virtual event, in May 17–19, 2022. The conference was held virtually due to the COVID-19 crisis. The 18 full papers and 2 short papers presented were carefully reviewed and selected from 100 submissions. The scope of the conference covers all aspects related to the design and the development of these systems, including multi-core architectures, Concurrent and distributed algorithms, parallel/concurrent/distributed programming, distributed databases, big data applications and systems, cloud systems, networks, security, and formal verification. They were organized in topical sections as follows: Distributed System; Networking; Verification; Security.
Wind Turbines in Managed Forests Partially Displace Common Birds
Abstract: Wind turbines are increasingly being installed in forests, which can lead to land use disputes between climate mitigation efforts and nature conservation. Environmental impact assessments precede the construction of wind turbines to ensure that wind turbines are installed only in managed or degraded forests that are of potentially low value for conservation. It is unknown, nevertheless, if animals deemed of minor relevance in environmental impact assessments are affected by wind turbines in managed forests. We investigated the impact of wind turbines on common forest birds, by counting birds along an impact-gradient of wind turbines in 24 temperate forests in Hesse, Germany. During...
Regeneration of Urban Forests as Influenced by Fragmentation, Seed Dispersal Mode and the Legacy Effect of Reforestation Interventions
Abstract: Urban forests are highly fragmented in mega-cites, acting as islands in terms of preserving species diversity. To maintain the ecological services of urban forests, management measures such as reforestation have been implemented, which might have a long-term effect on biodiversity. To understand how fragmentation and reforestation affect the natural regeneration of urban forests, we investigated the relationship between forest area, isolation and seed dispersal mode and the diversity and composition of woody species at the tree, seedling, and sapling stages in 28 secondary forests of the mega-city of Wuhan, China. We found that the alpha diversity of woody species was positively co...
Common Seed Dispersers Contribute Most to the Persistence of a Fleshy-fruited Tree
Abstract: Mutualistic interactions are by definition beneficial for each contributing partner. However, it is insufficiently understood how mutualistic interactions influence partners throughout their lives. Here, we used animal species-explicit, microhabitat-structured integral projection models to quantify the effect of seed dispersal by 20 animal species on the full life cycle of the tree Frangula alnus in Białowieża Forest, Eastern Poland. Our analysis showed that animal seed dispersal increased population growth by 2.5%. The effectiveness of animals as seed dispersers was strongly related to the interaction frequency but not the quality of seed dispersal. Consequently, the projected population decline due to simulated species extinction was driven by the loss of common rather than rare mutualist species. Our results support the notion that frequently interacting mutualists contribute most to the persistence of the populations of their partners, underscoring the role of common species for ecosystem functioning and nature conservation
Classifying the Activity States of Small Vertebrates Using Automated VHF Telemetry
The most basic behavioural states of animals can be described as active or passive. However, while high-resolution observations of activity patterns can provide insights into the ecology of animal species, few methods are able to measure the activity of individuals of small taxa in their natural environment. We present a novel approach in which the automated VHF radio-tracking of small vertebrates fitted with lightweight transmitters ( 0.2 g) is used to distinguish between active and passive behavioural states. A dataset containing 3 million VHF signals was used to train and test a random forest model in the assignment of either active or passive behaviour to individuals from two forest-dwel...
