Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana

Limnology and Oceanography: Methods, EarlyView.
Abstract Climate change is accelerating the deoxygenation of aquatic ecosystems, so understanding its effects on biological processes is increasingly critical. An emerging method for inducing hypoxia during experimentation utilizes sodium sulfite (SSI) to scavenge oxygen; however, it remains unclear if hypoxia‐inducing concentrations of SSI are toxic ...

Simulating controlled drainage and hydrological connections in a cultivated peatland field

Vadose Zone Journal
Cultivated peatlands are increasingly regarded as hot spots due to climate change and other environmental concerns. Flexible water management, such as controlled drainage, is proposed to optimize cultivation and reduce environmental risks in peatland ...

Long-term effect of forest renewal on the water regime in the small experimental watershed Červík

Soil and Water Research, 2009
The small, fully forested watershed Červík (CE) is situated in the part of the Beskydy Mts called the Zadní hory Mts Since November 1953, water balance has been measured in this place with the goal to find out experimentally the changes of the outflow ...

The role of tropical forests in supporting biodiversity and hydrological integrity: a synoptic overview [PDF]

Conservation of high-biodiversity tropical forests is sometimes justified on the basis of assumed hydrological benefits - in particular, the reduction of flooding hazards for downstream floodplain populations.

Flow cytometric phytoplankton concentration and optical properties across instruments and laboratories

Limnology and Oceanography: Methods, EarlyView.
Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

Limnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

Limnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...
