Determining the probability of cyanobacterial blooms: the application of Bayesian networks in multiple lake systems [PDF]
, 2015 A Bayesian network model was developed to assess the combined influence of nutrient conditions and climate on the occurrence of cyanobacterial blooms within lakes of diverse hydrology and nutrient supply.

Limnology and Oceanography: Methods, EarlyView.Abstract Greenhouse gas (GHG) emissions from freshwater ecosystems contribute significantly to global carbon budgets, yet they remain poorly constrained due to limited high‐frequency measurements. We tested a low‐cost, high‐frequency GHG measurement system in a long‐term mesocosm experiment in Lemming, Denmark, over a 7‐month period, focusing on CO2 ...

Resilient Flow Regimes in the Rio Grande—Río Bravo Basin
River Research and Applications, EarlyView.ABSTRACT Water is essential for human development and is an indispensable resource for economic activity and a country's growth. However, current water practices, along with increasing land‐use change, climate change, and agricultural practices, have significantly altered the hydrological cycle and water availability.

Detection and distribution of Craspedacusta sowerbii: Observations of medusae are not enough [PDF]
, 2012 The freshwater cnidarian Craspedacusta sowerbii, native to the Yangtze valley, has invaded lakes and ponds throughout the world. Most distribution records have to date been based on observations of the medusa (jellyfish) stage, including numerous recent ...

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges
River Research and Applications, EarlyView.ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

River Research and Applications, EarlyView.ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that
