Effects Of Ecologically Relevant Concentrations Of Nitrate On Behavior In Betta Splendens, Sarah Janson
Effects Of Ecologically Relevant Concentrations Of Nitrate On Behavior In Betta Splendens, Sarah Janson
Honors College
Nitrate is a ubiquitous pollutant that is becoming more prevalent in both fresh and saltwater environments. Short term effects are often studied, but an organism’s response to stress can change due to whatever the stressor is. In order to research this, a study was run using environmentally relevant nitrate treatments (0 mg/L, 10 mg/L NO3-N, and 100 mg/L NO3-N) to see the effect of nitrate on scototaxis behaviors, a measure of anxiety. This study used Betta splendens because they are easy to rear and have very well documented behaviors. In addition to the scototaxis, the effect of temperature on mortality …

Nitrates are an important compound in nature. However, through a number of human activities, nitrate concentrations have exponentially increased in nature. Most of the anthropogenic nitrates come from fertilizers, sewage water, and other wastewater. These nitrates contaminate the water which can get into lakes, rivers, ponds, and other natural bodies of water. Betta splendens are a well studied species in the animal behavior community. They have defined and quantifiable displays and characteristics during aggressive and mating ritual behavior. Betta splendens live in freshwater habitats that have most likely come in contact with the increased levels of nitrates. This study observed …
