Scientific Opinion on the evaluation of the pest risk analysis on Pomacea insularum, the island apple snail, prepared by the Spanish Ministry of Environment and Rural and Marine Affairs

open access: yesEFSA Journal, 2012
The Panel considers the Spanish pest risk analysis (PRA) to be clear and to provide appropriate supporting evidence. However, (i) the environmental impact assessment is incomplete and (ii) the estimates for the potentially endangered area are too limited.

Wetlands as natural assets [PDF]

open access: yesHydrological Sciences Journal, 2011
Abstract As the services of wetlands are uniquely related to hydrological processes, they result in a wide range of benefits to humankind. Although this facilitates the characterization of wetlands as natural assets, there are measurement problems. Because wetland services are nearly always non-marketed, they need to be explicitly valued to determine ...

Natural wetland emissions of methylated trace elements [PDF]

open access: yesNature Communications, 2014
Natural wetlands are well known for their significant methane emissions. However, trace element emissions via biomethylation and subsequent volatilization from pristine wetlands are virtually unstudied, even though wetlands constitute large reservoirs for trace elements. Here we show that the average volatile fluxes of selenium (

Restoration enhances wetland biodiversity and ecosystem service supply, but results are context-dependent: a meta-analysis. [PDF]

open access: yesPLoS ONE, 2014
Wetlands are valuable ecosystems because they harbor a huge biodiversity and provide key services to societies. When natural or human factors degrade wetlands, ecological restoration is often carried out to recover biodiversity and ecosystem services (ES)

Amphibian population responses to mitigation: Relative importance of wetland age and design

open access: yesEcological Indicators, 2021
Wetland creation is a common practice to mitigate for the loss of natural wetlands. However, there is still uncertainty about how effectively created wetlands replace habitat provided by natural wetlands.

Are the Romanian natural protected areas properly covering the wetland? [PDF]

open access: yesScientific Annals of the Danube Delta Institute, 2020
Wetlands host an important biodiversity, provide important ecosystem services, and are threatened and vulnerable ecosystems, representing a priority for the conservation of biodiversity.

Reproductive Ecology and Nesting Site Characteristics of Four-Toed Salamanders (Hemidactylium scutatum) in Natural and Constructed Upland-Embedded Wetlands on the Appalachian Plateau, Kentucky

open access: yesDiversity, 2022
Many forested freshwater wetlands have been altered or destroyed, and wetlands are constructed to offset loss. However, they do not always replace the function of natural wetlands.

Temporal and Spatial Variation of Wetland CH4 Emissions from the Qinghai–Tibet Plateau under Future Climate Change Scenarios

open access: yesAtmosphere, 2022
Wetlands are an important natural source of methane (CH4), so it is important to quantify how their emissions may vary under future climate change conditions. The Qinghai–Tibet Plateau contains more than a third of China’s wetlands.
