Abstract As the United Nations develops a post-2020 global biodiversity framework for Convention on Biological Diversity, attention is focusing how new goals and targets ecosystem conservation might serve its vision of ‘living in harmony with nature’ 1,2 . Advancing dual imperatives to conserve sustain services requires reliable resilient generalizations predictions about responses environmental change management 3 Ecosystems vary their biota 4 , service provision 5 relative exposure risks 6...
Catchment urbanization can alter physical, chemical, and biological attributes of stream ecosystems. In particular, changes in land use may affect the dynamics organic matter decomposition, a measure ecosystem function. We examined leaf-litter decomposition 18 tributaries St. Johns River, Florida, USA. Land all catchments ranged from 0% to 93% urban which translated 66% total impervious area (TIA). Using litter-bag technique, we measured mass loss, fungal biomass, macroinvertebrate biomass...

The spatial extent of seagrass is poorly mapped, and knowledge historical loss limited. Here, we collated empirical qualitative data using systematic review methods to provide unique analysis on occurrence in the United Kingdom. We document 8,493 ha recently mapped Kingdom since 1998. This equates an estimated 0.9 Mt carbon, which, current carbon market represents about £22 million. Using simple models estimate declines triangulated against habitat suitability models, evidence catastrophic...
Repeat observations underpin our understanding of environmental processes, but financial constraints often limit scientists’ ability to deploy dense networks conventional commercial instrumentation. Rapid growth in the Internet-Of-Things (IoT) and maker movement is paving way for low-cost electronic sensors transform global monitoring. Accessible inexpensive sensor construction also fostering exciting opportunities citizen science participatory research. Drawing on 6 years developmental work...

Promoting a fish as flagship species (i.e. charismatic animal that promotes awareness) is management tool to improve the effectiveness of conservation measures. However, be successful this approach requires strong stakeholder support. To investigate feasibility and degree support in India, semi‐structured interviews were conducted with forest managers, anglers village members U ttarakhand. Stakeholders supportive golden mahseer was favoured because economic benefits associated recreational angling.
ABSTRACTABSTRACTNon-native and invasive species of plants animals represent a major threat to global biodiversity associated ecosystem services. Developing an understanding processes, impacts controls invasions is important challenge for biogeographers ecologists. Within the rapidly-expanding knowledge invasions, urban ecosystems remain curiously under-explored. Despite paucity research it known that cities, with their unique socio-ecological environmental characteristics, exhibit high...
Waterfalls are geomorphic features that often partition streams into discrete zones. Our study examined aquatic communities, litter decomposition and periphyton growth rates for above- below-waterfall pools in Ulu Temburong National Park, Brunei. We observed higher fish densities (0.24 m−2 vs. 0.02 above-waterfall pools) shrimp abundance (eight shrimp/pool less than one pools). However, macroinvertebrate (excluding shrimp) were similar among both pool types. Ambient was 2013 (4.3 2.8 g 2014...
Accurate hydrological data with high spatial resolution is important for flood risk and water resource management, particularly under the context of climate change. The cost monitoring networks, as well characteristics environment itself, can be a barrier to meeting these requirements, however. This study covers design testing low-cost, "build-it-yourself", instream depth sensor providing an assessment its potential in future projects. low-cost was built using Arduino microcontroller,...
Summary 1. The effect of channel drying on macroinvertebrate production was studied at the habitat and reach scale in a catchment drained by intermittent streams Maine, U.S.A. includes two first‐order their second‐order confluence. Six reaches were selected for study based differences slope cover (bedrock, riffle/run, debris dam pool). Stream water each acidic oligotrophic. 2. had different degrees drying. In reaches, surface flow ceased earlier season longer periods than reaches. Regardless...
Seagrass meadows provide a multitude of ecosystem services, including capacity to sequester carbon dioxide (CO2) within their sediments. research in the UK is lacking and there no published data on sediment (C) seagrass meadows. We sampled 13 Zostera marina along southwest coast assess variability sedimentary organic (OC) stocks. The study sites were considered representative sub-tidal Z. UK, spanning gradient sheltered exposed sites, varying formation, size density, but found same...
Abstract Freshwater crayfish can be successful invaders that threaten native biota and aquatic ecosystems in numerous countries worldwide. Nonetheless, the inability of conventional survey techniques like trapping handsearching to yield quantitative population data has limited understanding invasion biology associated ecological impacts. Here, we employed a novel ‘triple drawdown’ (TDD) method sample invasive populations signal Pacifastacus leniusculus headwater stream Northern England. The...
Historically studies have equated the presence of litter to act littering; however, results a disposal behaviour analysis suggest that connection is not as straightforward. In this study concept polite littering was established, where if there are no means for disposal, placed neatly in creative spaces lieu littering. As common perception towards it done flagrant and untidy way, littering, individuals negotiate their actions non-contributory. Ultimately, found methods accidental accounted...
