Biodiversity recovery and transformation impacts for wetland biodiversity.

Life Cycle Assessment (LCA) methods for land use take both occupation and transformation impacts into account. However, for wetlands and impacts from water consumption, it is so far not possible to account for transformation impacts. It is our goal to close this research gap, by determining wetland recovery times and developing characterization factors for transformation. To do this, we conducted a meta-analysis of 59 studies analyzing biodiversity recovery in wetlands subject to passive and active restorat...


How is biodiversity changing in response to ecological restoration in terrestrial ecosystems? A meta-analysis in China.

Biodiversity is an important ecosystem characteristic, and is vital for maintaining ecosystem health and stability. However, biodiversity was often ignored in previous Chinese restoration planning and design due to its complex roles and the unclear mechanisms in providing human well-being. In order to evaluate the response of biodiversity to ecological restoration in terrestrial ecosystems, we assembled biodiversity in different metrics and different organisms and generated a large dataset comprised 2099 ob...

Half century change of interactions among ecosystem services driven by ecological restoration: Quantification and policy implications at a watershed scale in the Chinese Loess Plateau.

The concept of Ecosystem Service (ES) has provided an underpinning framework for ecological restoration research and applications. Ecological restoration is a corrective intervention that aims to reverse land degradation and to contribute to the 2030 Global Sustainable Development goal of Land Degradation Neutrality. It is critical to investigate the long-term effects of ecological restoration and land use change on ESs and ES interactions (synergies or trade-offs) to better understand the mechanisms suppor...


Attosecond Control of Restoration of Electronic Structure Symmetry.

Laser pulses can break the electronic structure symmetry of atoms and molecules by preparing a superposition of states with different irreducible representations. Here, we discover the reverse process, symmetry restoration, by means of two circularly polarized laser pulses. The laser pulse for symmetry restoration is designed as a copy of the pulse for symmetry breaking. Symmetry restoration is achieved if the time delay is chosen such that the superposed states have the same phases at the temporal center. ...

Seagrass and macrophyte mediated CO2 and CH4 dynamics in shallow coastal waters.

Seagrass meadows are among the most important coastal/ marine ecosystems for long-term carbon storage and conditioning of coastal waters. A combined air-water flux of CO2 and CH4 from the seagrass meadows was studied for the first time from Asia's largest brackish-water lagoon, Chilika, India. Ecosystem-based comparisons were carried out during two hydrologically different conditions of dry and wet seasons in the seagrass dominated southern sector (SS); macrophyte-dominated northern sector (NS); the largely...

The effects of El Niño-Southern Oscillation events on intertidal seagrass beds over a long-term timescale.

El Niño-Southern Oscillation (ENSO) events can cause dramatic changes in marine communities. However, we know little as to how ENSO events affect tropical seagrass beds over decadal timescales. Therefore, a diverse array of seagrass (Thalassia hemprichii) habitat types were surveyed once every three months for 16 years (January 2001 to February 2017) in a tropical intertidal zone that is regularly affected by both ENSO events and anthropogenic nutrient enrichment. La Niña and El Niño events had distinct ...

Variability of UK seagrass sediment carbon: Implications for blue carbon estimates and marine conservation management.

Seagrass meadows provide a multitude of ecosystem services, including a capacity to sequester carbon dioxide (CO2) within their sediments. Seagrass research in the UK is lacking and there is no published data on sediment carbon (C) within UK seagrass meadows. We sampled 13 Zostera marina meadows along the southwest coast of the UK to assess the variability in their sedimentary organic carbon (OC) stocks. The study sites were considered representative of sub-tidal Z. marina meadows in the UK, spanning a grad...

Influence of surface flattening on biodiversity of terrestrial arthropods during early stages of brown coal spoil heap restoration.

Heterogeneity of environmental conditions is the crucial factor supporting biodiversity in various habitats, including post-mining sites. The effects of micro-topographic heterogeneity on biodiversity and conservation potential of arthropod communities in post-industrial habitats had not been studied before now. At one of the largest European brown coal spoil heaps, we sampled eight groups of terrestrial arthropods with different life strategies (moths, spiders, ground beetles, ants, orthopteroids, centiped...

Evidence of forest restoration success and the conservation value of community-owned forests in Southwest China using dung beetles as indicators.

Protection of the world's remaining forests and biodiversity is a matter of global concern. Yunnan, China is home to China's only mainland tropical rainforests, and 20% of China's total biodiversity. Despite restoration measures and establishment of new protected areas, this region is still experiencing biodiversity loss due to inadequate management and monitoring. We evaluate restoration success of China's tropical forests in Xishuangbanna National Nature Reserve (XSBN-NNR), Yunnan, China using dung beetle...

Accounting for no net loss: A critical assessment of biodiversity offsetting metrics and methods.

Biodiversity offset strategies are based on the explicit calculation of both losses and gains necessary to establish ecological equivalence between impact and offset areas. Given the importance of quantifying biodiversity values, various accounting methods and metrics are continuously being developed and tested for this purpose. Considering the wide array of alternatives, selecting an appropriate one for a specific project can be not only challenging, but also crucial; accounting methods can strongly influe...

Identification of conservation and restoration priority areas in the Danube River based on the multi-functionality of river-floodplain systems.

Large river-floodplain systems are hotspots of biodiversity and ecosystem services but are also used for multiple human activities, making them one of the most threatened ecosystems worldwide. There is wide evidence that reconnecting river channels with their floodplains is an effective measure to increase their multi-functionality, i.e., ecological integrity, habitats for multiple species and the multiple functions and services of river-floodplain systems, although, the selection of promising sites for res...

Facing the future for grassland restoration - What about the farmers?

In line with the 2010 Aichi Convention for Biological Diversity, the European Union has a goal to restore 15% of degraded ecosystems and their services by the year 2020 (target 2, Europe 2020). This includes restoration of semi-natural grasslands (SNGs). Management of both intact and restored SNGs is dependent on people's willingness to manage them. Due to low profitability, management abandonment still occurs all over Europe, which highlights the need to raise farmers' and landowners' perspectives. In this...

A multi-criterion approach for prioritizing areas in urban ecosystems for active restoration following invasive plant control.

Resources for biodiversity conservation and invasive plant management are limited, and restoring invaded vegetation is labour-intensive and expensive. Managers must prioritize their actions to achieve their goals efficiently and effectively. They must distinguish between areas that require only the removal of invasive alien plants ("passive restoration") from those that require additional restoration measures ("active restoration"). This study used a multi-criterion approach (Analytical Hierarchical Process...

A changing climate for seagrass conservation?

Tropical coral reefs are threatened and in decline, and their future is highly uncertain. With increasing rates of climate change and rising global temperatures, people looking to coral reefs for food and income may increasingly have to rely on resources from other habitats. Efforts to protect and conserve the coral reefs we have left are critical for a suite of economic, ecological, cultural and intrinsic reasons, but there is also an urgent need to take heed of the future scenarios from coral reefs and br...

Ecological and socioeconomic effects of ecological restoration in China's Three Rivers Source Region.

The Three Rivers Source Region, in the central Qinghai-Tibet Plateau, has a sensitive and fragile ecological environment. Adverse changes in climate and human activities have degraded the grassland ecosystems. To mitigate or reverse the degradation, alleviate rural poverty, and stimulate economic development, ecological restoration projects have been implemented. In the present study, our goal was to assess the ecological and socioeconomic effects of these programs based on land-use change, grassland NPP, a...

Demographic costs and benefits of natural regeneration during tropical forest restoration.

For tropical forest restoration to result in long-term biodiversity gains, native trees must establish self-sustaining populations in degraded sites. While many have asked how seedling recruitment varies between restoration treatments, the long-term fate of these recruits remains unknown. We address this research gap by tracking natural recruits of 27 species during the first 7 years of a tropical forest restoration experiment that included both planted and naturally regenerating plots. We used an individu...

Beach-cast seagrass wrack contributes substantially to global greenhouse gas emissions.

Seagrass ecosystems have received a great deal of attention recently for their ability to capture and store carbon, thereby helping to mitigate climate change. However, their carbon-sink capacity could be offset somewhat if exported plant material - which accounts for ∼90% of total leaf production - undergoes microbial breakdown and is emitted into the atmosphere as a greenhouse gas. Here we measured emissions (CO and CH) from the breakdown of exported seagrass plant material, focusing on beach-cast 'wrac...

Community-based native seed production for restoration in Brazil - the role of science and policy.

Large-scale restoration programs in the tropics require large volumes of high quality, genetically diverse and locally adapted seeds from large number of species. However, scarcity of native seeds is a critical restriction to achieve restoration targets. In this paper, we analyze three successful community-based networks that supply native seeds and seedlings for Brazilian Amazon and Cerrado restoration projects. In addition, we propose directions to promote local participation, legal, technical and commerc...

Expected limits on the ocean acidification buffering potential of a temperate seagrass meadow.

Ocean acidification threatens many marine organisms, especially marine calcifiers. The only global-scale solution to ocean acidification remains rapid reduction in CO emissions. Nevertheless, interest in localized mitigation strategies has grown rapidly because of the recognized threat ocean acidification imposes on natural communities, including ones important to humans. Protection of seagrass meadows has been considered as a possible approach for localized mitigation of ocean acidification due to their la...

Leisure as an End, Not Just a Means, in Occupational Therapy Intervention.

Leisure is commonly treated as a means instead of an end goal of intervention. This approach, influenced by history and society's past values, does not reflect the fact that leisure is meaningful and unique to its participants and has a significant effect on their health. On the basis of the core values of the occupational therapy profession and its role in the health care system, in this article we advocate that occupational therapists should expand their focus to include leisure as a goal of intervention....

Color Repair of a Composite Resin Restoration.

Fractured teeth with both enamel and dentin involvement might be treated with adhesive composite resin restorations. In cases where a perfect color match between the composite restoration and the remaining tooth structure is not achieved, a repair might be carried out to correct the color of restoration. This procedure avoids the restoration replacement, preserving tooth structure without compromising the esthetic outcome.

Appropriate application of information from biodiversity databases is critical when investigating species distributions and diversity: a comment on Dallas et al. ().

Using data from biodiversity informatics resources, Dallas et al. (Ecol. Lett., 20, 2017, 1526-1533) suggested limited relationships between climate and local abundance among several taxonomic groups. Investigation of a subset of these data suggests that their results may be misleading due to inappropriate application of the biodiversity data.

Evolving Biodiversity Patterns in Changing River Networks.

Biodiversity patterns are governed by landscape structure and dispersal strategies of residing organisms. Landscape, however, changes, and dispersal strategies evolve with it. It is unclear how these biological and geomorphological changes interplay to affect biodiversity patterns. Here we develop metacommunity models that allow for dispersal evolution and implement them in river networks with different structures, mimicking the geomorphological dynamics of fluvial landscape. For a given dispersal kernel, a...

Spatial and topical imbalances in biodiversity research.

The rapid erosion of biodiversity is among the biggest challenges human society is facing. Concurrently, major efforts are in place to quantify changes in biodiversity, to understand the consequences for ecosystem functioning and human wellbeing, and to develop sustainable management strategies. Based on comprehensive bibliometric analyses covering 134,321 publications, we report systematic spatial biases in biodiversity-related research. Research is dominated by wealthy countries, while major research defi...

Overcoming the dichotomy of implementing societal flood risk management while conserving instream fish habitat - A long-term study from a highly modified urban river.

Flood Risk Management (FRM) is often essential to reduce the risk of flooding to properties and infrastructure in urban landscapes, but typically degrades the habitats required by many aquatic animals for foraging, refuge and reproduction. This conflict between flood risk management and biodiversity is driven by conflicting directives, such as the EU Floods and Water Framework Directives, and has led to a requirement for synergistic solutions for FRM that integrate river restoration actions. Unfortunately, ...
