Nonlinear thinking in ecology and evolution: applying the threshold elemental ratio across levels of ecological organization Open
Nonlinear dynamics govern ecological processes; thus, understanding thresholds is important for measuring and forecasting the effects of climate change and management of natural resources. However, identifying whether and how such threshol…

Spatial distribution of rare and common phytoplankton taxa is controlled by geospatial and physicochemical variables Open
Phytoplankton are commonly used as an ecological tool in assessing water quality and indicating ecosystem health. The purpose of this study was to explore the effects of geospatial and physicochemical variables on variation in phytoplankto…

Current and Historical Resource Nitrogen Supply Affects the Eco‐Physiological Traits and the Ionome of a Diazotrophic Cyanobacterium Open
Diazotrophic cyanobacteria can overcome nitrogen (N)‐limitation by fixing atmospheric N 2 ; however, this increases their energetic, iron, molybdenum, and boron costs. It is unknown how current and historic N‐supplies affect cyanobacterial…

Diazotrophy modulates cyanobacteria stoichiometry through functional traits that determine bloom magnitude and toxin production Open
Harmful cyanobacterial blooms are an increasing threat to water quality. The interactions between two ecophysiological functional traits of cyanobacteria, diazotrophy (nitrogen [N]‐fixation) and N‐rich cyanotoxin synthesis, have never been…

The effects of salinity and N : P on N‐rich toxins by both an N‐fixing and non‐N‐fixing cyanobacteria Open
Freshwater ecosystems are experiencing increased salinization. Adaptive management of harmful algal blooms (HABs) contributes to eutrophication/salinization interactions through the hydrologic transport of blooms to coastal environments. W…

Developing and Assessing Empathy through Study of Christian Heresies in an Introductory Christian History and Theology Course Open
Empathy is a nebulous concept that is nonetheless touted in many schools’ curricular goals and striven for by many instructors. Unfortunately, lack of a shared definition and reliable measures for empathy hamper efforts to determine whethe…

Biological Stoichiometry Regulates Toxin Production in Microcystis aeruginosa (UTEX 2385) Open
Harmful algal blooms (HABs) are increasing in magnitude, frequency, and duration globally. Even though a limited number of phytoplankton species can be toxic, they are becoming one of the greatest water quality threats to public health and…
