Article
Full-text available
Background Urban agriculture is potentially an important piece of the food security puzzle for a rapidly growing urban world population. Community gardening is also promoted as a safe and viable form of exercise for aging populations in crowded settings where opportunities to participate in other action activities may be limited. Knowledge of poten...
Article
Full-text available
Functional traits offer generalizability to the prediction of ecosystem processes such as production, and community-weighted mean trait values are increasingly used for such predictions. However, the underlying causal direction between traits and ecosystem processes are often indirect and sometimes even tenuous. In this study, we aimed to uncover u...
Article
Full-text available
Carbon and nitrogen losses from degraded wetlands and methane emissions from flooded wetlands are both important sources of greenhouse gas emissions. However, the net-exchange dependence on hydrothermal conditions and wetland integrity remains unclear. Using a global-scale in situ database on net greenhouse gas exchanges, we show diverse hydrology-...
Article
We investigated processes contributing to periodic acidification events in headwater streams of Nee Soon Forest Catchment (NSFC) in Singapore by monitoring hydrochemical changes in response to rainfall inputs. Stream chemistry response to most rainfall events was characterised by decreases in pH from means ranging from 5.1 to 5.3 to below 4.8 to 5....
Article
As mountain tourism rapidly expands in remote landscapes, there is a critical need for improved disaster risk management to ensure the safety of tourists and industry workers, safeguard infrastructure designed to support tourism and service industries (e.g., transportation), as well as protect the local economies that have come to depend on tourism...
Article
Full-text available
Peatlands are both responding to and influencing climate change. While numerous studies on peatland carbon dynamics have been published in boreal and temperate regions for decades, a much smaller yet growing body of scientific articles related to tropical peatlands has recently been published, including from previously overlooked regions such as th...
Article
Full-text available
During a university class project related to climate change mitigation strategies, we utilized a university green space as a “living laboratory” for collaborative learning exercise to estimate landscape-level carbon biomass storage. The key objective of the exercise was to foster sustainability awareness with regard to the effectiveness of tree-pla...
Article
Decomposition is a key ecosystem function, and the rate of decomposition in forests affects their carbon storage potentials. Processes and factors determining leaf litter decomposition rates in dry‐land and temperate forests are well understood, but these are generally poorly studied in tropical wetland forests, especially freshwater swamp forests...
Article
Our assessment of 30 water bodies in the vicinity of the Mae Moh coal mine and power station in northern Thailand does not indicate substantial water quality management challenges to developing fisheries/aquaculture in peripheral reservoirs and streams. Negative water quality issues such as high concentrations of arsenic (2-17 μg/L) and ions includ...
Article

The authors wish to make the following correction to this paper: The author name “Zahra Kalantary” should be “Zahra Kalantari” [...]
Article
Full-text available
Wetlands are often vital physical and social components of a country's natural capital, as well as providers of ecosystem services to local and national communities. We performed a network analysis to prioritize Sustainable Development Goal (SDG) targets for sustainable development in iconic wetlands and wetlandscapes around the world. The analysis...
Article
Full-text available
• Freshwater swamp forests are poorly studied but highly threatened freshwater habitats, especially in Southeast Asia. Very little is known about the environmental factors associated with the assembly and spatial distribution of fish communities in these acid‐water habitats, although such knowledge is of immense importance for conservation and mana...
Article
Full-text available
The Nee Soon stream drainage in the Central Catchment Nature Reserve is virtually the last remaining fragment of primary freshwater swamp forest in Singapore. The forest type has been poorly studied in the Southeast Asia. The hydrology, water quality, as well as aquatic flora and fauna all have great theoretical and practical significance. The ecol...
Article
Full-text available
Roads are a pervasive form of disturbance with potential to negatively affect ecohydrological processes. Some of the fastest and most rapid growth is occurring in developing countries, particularly in the tropics, where political agendas are often focused on strengthening the economy, improving infrastructure, bolstering national security, achievin...
Book
Full-text available
Aquatic macroinvertebrates and lower vertebrates were surveyed from the last remaining freshwater swamp forest in Singapore. Ecological data was collated from three years of field work. This book is a guide to the macroinvertebrates and the fish of the Nee Soon Swamp Forest, with identification keys provided as well.
Article
Full-text available
Many degraded ecosystems are subject to restoration attempts, providing new opportunities to unravel the processes of ecological community assembly. Restoration of previously drained northern peatlands, primarily to promote peat and carbon accumulation, has created hundreds of thousands of new open water pools. We assessed the potential benefits of...
Article
Full-text available
Peatlands are found around the world and cover similar to 3.4% of the Earth's surface. In the UK, peatlands cover 17.2% or similar to 1.58 Mha of the land surface and occur mainly in upland areas covering the headwaters of most major British rivers. However, large areas are now subject to prescribed vegetation burning despite policy guidance that r...
Article
Full-text available
Summary Rotational vegetation burning in peatlands is undertaken predominantly to increase habitat suitability and food availability for red grouse Lagopus lagopus (Linnaeus). Red grouse shooting contributes to the upland economy and is seen as a traditional leisure activity. However, there is concern that burning can have detrimental effects on pe...
Article
Full-text available
1. Drainage of peat-dominated catchments across the world has caused widespread degradation of peat and freshwater ecosystem services. In the UK, an estimated £500 million has been spent over the last decade blocking drains to reverse these changes. The practice raises water-tables to induce rewetting and promote peat aggradation. However, the pote...
Article
Full-text available
Headwater stream ecosystems draining blanket peat-dominated catchments occur in many high-latitude river systems. These systems are thought to be very sensitive to threats from climate change, and land-use modification including artificial drainage, overgrazing, afforestation and vegetation burning. This study examined ten peatland streams in the h...
Article
Full-text available
Despite the known importance of water temperature for river ecosystems, the thermal regime of streams and rivers can be heavily modified by afforestation. Although the nature of the heat budget affecting streams in forested catchments shows high variability in space and time, most of the studies of stream temperature response to afforestation have...
Article
Full-text available
Peatlands are important ecosystems for carbon (C) storage, provision of water resources and biodiversity. UK blanket peats represent 10-15% of those found worldwide. While many peatlands continue to be managed through artificial drainage and vegetation burning, it has long been recognized that local habitats and ecological diversity are strongly in...
Conference Paper
Full-text available
Scientists have long recognised that human-induced landscape modifications have altered stream systems by changing the hydrology, geomorphology, water quality and biota. Peatlands are important global systems for carbon storage, water resources and biodiversity. Many UK blanket peats are intensively managed through artificial drainage, rotational h...
Article
Full-text available
Herbivore-induced defences appear ubiquitous across most biomes and habitats. Yet the direct correlation between induced changes in host plant chemistry and the population dynamics of the herbivore remain untested in many systems. In plant-herbivore interactions in the terrestrial environment, indirect or tritrophic interactions appear a successful...
Article
1. It is well understood that herbivory can cause plants to elevate production of defensive chemicals in their tissues. One of the key questions in understanding patterns of potential coevolutionary links between plant and herbivore is `what switches these induced plant defences on?' Until cues are identified, understanding the evolutionary and eco...
