Atmospheric pollution has implications for the health and diversity of temperate forests covering large parts of central Europe. Long-term elevated anthropogenic deposition of nitrogen (N) is driving forest ecosystems from the limitation by N to other nutrients and is found to affect tree health and ectomycorrhizal fungi (EMF), which most trees depend on for nutrient uptake. However, the consequen

Background: Globally, high amounts of food are wasted due to insufficient quality and decay. Although pollination has been shown to increase crop quality, a possible impact on shelf life has not been quantitatively studied. Results: We tested how shelf life, represented by fruit decay, firmness and weight, changes as a function of pollination limitation in two European, commercially important stra

In order to understand the ecological effects of climate change it is essential to forecast suitable areas for species in the future. However, species' ability to reach potentially suitable areas is also critical for species survival. These 'range-shift' abilities can be studied using life-history traits related to four range-shift stages: emigration, movement, establishment, and proliferation. He

Stakeholder participation is considered a key principle for sustainable development in the context of natural resource and disaster risk management. Participatory modelling (PM) is an interactive and iterative process in which stakeholder involvement is supported by modelling and communication tools. Planning and decision-making for sustainable development (SD)integrate three substantive dimension

The article aims to illustrate the multifaceted interlink between climate change, heat, and human rights and discuss in what ways international human rights law may be used to support the development and implementation of policy at various levels to limit adverse effects of climate change on humans in general and right to health in particular. This is done by overviewing the possibilities and limi

Local biodiversity can be expected to be similar worldwide if environmental conditions are similar. Here, we hypothesize that tropical ant communities with different types of regional species pools but at similar habitat types in Brazil and Indonesia show similar diversity patterns at multiple spatial scales, when comparing (1) the relative contribution of alpha and beta diversity to gamma diversi

The ecosystem services (ES) concept refers to benefits that humanity receives from nature. Investigating how this concept has been embraced within urban planning is important when assessing the awareness of human dependence on natural functions and the potential for the ES concept to increase this awareness. We analyzed planning documents from three small and three large municipalities in southern

The conversion of tropical rainforest to agricultural systems such as oil palm alters biodiversity across a large range of interacting taxa and trophic levels. Yet, it remains unclear how direct and cascading effects of land-use change simultaneously drive ecological shifts. Combining data from a multi-taxon research initiative in Sumatra, Indonesia, we show that direct and cascading land-use effe

Presence of insects in agricultural habitat is affected by the surrounding circumstances such as the complexity and structure of landscape. Landscape structure is often formed as a consequence of the fragmentation of semi-natural habitat, which can negatively affect species richness and abundance of insects. This study was aimed to study the effect of complexity and structure of landscape on the d

Farmers are exposed to substantial weather and market related risks. Rational farmers seek to avoid large losses. Future climate change and energy price fluctuations therefore make adaptating to increased risks particularly important for them. Managing soil natural capital—the capacity of the soil to generate ecosystem services of benefit to farmers—has been proven to generate the double dividend:

A model for global supply of sand, gravel and cut stone for construction based on a system dynamics model was developed for inclusion in the WORLD6 model. The Sand-Gravel-Stone model simulates production and market supply, demand and price for natural sand and gravel, sand and gravel from crushed rock and cut stone. The model uses market mechanisms where the demand is depending on population size,

We have built a system dynamics model, WORLD6, that takes into account population, energy extraction, production and need, aspects social behaviour, material and metals recycling and important links to the economy. The model is ground-truthed by comparing with actual supply per person from 1900 till 2015 and run until 2400. Primary scarcity metrics are supply per person and year and stock-in-use p

A new model; WORLD6 was developed. WORLD6 differs from the earlier system dynamics world models in several aspects. Several modules link the economy, materials, metals, energy, population and politics in a dynamic system. The present version is a result of a dismantling of the World3 model (Meadows et al., 1972, 1992, 2004) with an extension and substitution of its resource module and economy modu

Agricultural intensification is one of the main causes for the current biodiversity crisis. While reversing habitat loss on agricultural land is challenging, increasing the farmland configurational heterogeneity (higher field border density) and farmland compositional heterogeneity (higher crop diversity) has been proposed to counteract some habitat loss. Here, we tested whether increased farmland

Citizen science is a powerful tool for connecting members of the public with research and for obtaining large amounts of data. However, it is far less commonly implemented in developing countries than in developed countries. We conducted a large-scale citizen-science program monitoring honey bee (Apis mellifera) colony losses in Argentina to examine how a national consortium composed of local coor

Land-use change is a major driver of biodiversity loss worldwide. Although biodiversity often shows a delayed response to land-use change, previous studies have typically focused on a narrow range of current landscape factors and have largely ignored the role of land-use history in shaping plant and animal communities and their functional characteristics. Here, we used a unique database of 220,000

The alarming loss of pollinator diversity world-wide can reduce the productivity of pollinator-dependent crops, which could have economic impacts. However, it is unclear to what extent the loss of a key native pollinator species affects crop production and farmer's profits. By experimentally manipulating the presence of colonies of a native bumblebee species Bombus pauloensis in eight apple orchar

The mutualistic symbiosis between forest trees and ectomycorrhizal fungi (EMF) is among the most ubiquitous and successful interactions in terrestrial ecosystems. Specific species of EMF are known to colonize specific tree species, benefitting from their carbon source, and in turn, improving their access to soil water and nutrients. EMF also form extensive mycelial networks that can link multiple
