Introduction
I am currently studying phytoplankton dynamics in mountain lakes and drivers of cyanobacteria blooms. I am more broadly interested in the drivers of algal community composition and nutrient dynamics in freshwater systems as well as bioindicators of water quality.

Article
Small, isolated, depressional wetlands increasingly exist in developed landscapes and are highly vulnerable to hydrologic alterations and eutrophication. Globally, grazing lands contain a significant number of these wetlands, and the practices of grazing, prescribed fire and fertilizing have all been shown separately to influence wetland nutrient d...

Flow regulation by dams can reduce hydrologic variability, and subsequently, alter river food webs. This study compared the summer algal and macroinvertebrate assemblages from the mainstem Eel River (Mainstem) below Cape Horn Dam to that of the unregulated Middle Fork Eel River (Middle Fork). Despite above average rainfall in 2017, flow regulation...

Understanding patterns and drivers of species distributions and abundances, and thus biodiversity, is a core goal of ecology. Despite advances in recent decades, research into these patterns and processes is currently limited by a lack of standardized, high-quality, empirical data that spans large spatial scales and long time periods. The National...

It is a critical time to reflect on the National Ecological Observatory Network (NEON) science to date as well as envision what research can be done right now with NEON (and other) data and what training is needed to enable a diverse user community. NEON became fully operational in May 2019 and has pivoted from planning and construction to operatio...
