Estimating intraspecific genetic diversity from community DNA metabarcoding data [PDF]

open access: yesPeerJ, 2018
Background DNA metabarcoding is used to generate species composition data for entire communities. However, sequencing errors in high-throughput sequencing instruments are fairly common, usually requiring reads to be clustered into operational taxonomic ...

A coupled terrestrial and aquatic biogeophysical model of the Upper Merrimack River watershed, New Hampshire, to inform ecosystem services evaluation and management under climate and land-cover change [PDF]

open access: yes, 2017
Accurate quantification of ecosystem services (ES) at regional scales is increasingly important for making informed decisions in the face of environmental change.

Biodiversity, community structure and function of biofilms in stream ecosystems [PDF]

open access: yes, 2015
Multi-species, surface-attached biofilms often dominate microbial life in streams and rivers, where they contribute substantially to biogeochemical processes.

Horizontal cooling towers: riverine ecosystem services and the fate of thermoelectric heat in the contemporary Northeast US [PDF]

open access: yes, 2013
The electricity sector is dependent on rivers to provide ecosystem services that help regulate excess heat, either through provision of water for evaporative cooling or by conveying, diluting and attenuating waste heat inputs. Reliance on these ecosystem

What lies beneath: Predicting seagrass below-ground biomass from above-ground biomass, environmental conditions and seagrass community composition

open access: yesEcological Indicators, 2021
Seagrass condition, resilience and ecosystem services are affected by the below-ground tissues (BGr) but these are rarely monitored. In this study we compiled historical data across northern Australia to investigate biomass allocation strategies in 13 ...

Linking movement and dive data to prey distribution models: new insights in foraging behaviour and potential pitfalls of movement analyses

open access: yesMovement Ecology, 2023
Background Animal movement data are regularly used to infer foraging behaviour and relationships to environmental characteristics, often to help identify critical habitat.

Shifts in leaf litter breakdown along a forest–pasture–urban gradient in Andean streams [PDF]

open access: yes, 2016
Tropical montane ecosystems of the Andes are critically threatened by a rapid land-use change which can potentially affect stream variables, aquatic communities, and ecosystem processes such as leaf litter breakdown.

Temporal variations in macroinvertebrate communities from the tributaries in the Three Gorges Reservoir Catchment, China

open access: yesRevista Chilena de Historia Natural, 2017
Background The seasonal variations in macroinvertebrate communities in tropical, temperate and subarctic regions have been observed and well documented to date, but similar studies conducted in subtropical rivers at the regional scale are relatively rare.

Drivers of multi-decadal nitrate regime shifts in a large European catchment

open access: yesEnvironmental Research Letters, 2022
Long-term monitoring shows evidence of persistent changes in the magnitude and timing of the seasonal pattern of nitrate concentrations in streams, with possibly grave effects on aquatic ecosystems. Seasonal patterns of stream nutrient concentrations are

Observational evidence for the convective transport of dust over the central United States [PDF]

open access: yes, 2016
Bulk aerosol composition and aerosol size distributions measured aboard the DC-8 aircraft during the Deep Convective Clouds and Chemistry Experiment mission in May/June 2012 were used to investigate the transport of mineral dust through nine storms ...
