Greenfield Lake in Wilmington, North Carolina has experienced recent problems with algal blooms, low dissolved oxygen levels, and fish kills. Many of these issues have likely been caused by high nutrient loading. This study examined lake sediment as a source and sink for phosphorus, the nutrient most often responsible for freshwater eutrophication.
A capture-recapture survey of bottlenose dolphins (Tursiops truncates) was conducted in the sounds, estuaries and near-shore waters of North Carolina in 2000 and 2006. The abundance of dolphins in this area remained relatively stable between the studies.
Atlantic bumper fish were once common, but rarely caught today in North Carolina. Their decline seems to reflect a response to changing water temperatures, cooler pre-1990 and warmer post-1990.
Pugheadedness is a trait exhibited by fish such as carp and striped bass. A spotted sea trout exhibiting pigheadedness was caught in January of 2013 in Smyrna Creek, a short tributary that enters Core Sound, Carteret County, North Carolina. Reason for the occurrence of this trait remains a mystery.
In North Carolina, dog-day cicadas appear in smaller numbers every year. Observations in a Charlotte, North Carolina suburban neighborhood revealed that the cicadas were being attacked by carpenter ants as they emerged from the ground. Thus, predation is an important regulator of dog-day cicadas.
