Acid-base accounting is a predictive geochemical method used to quantify the net acid-generating or acid-neutralizing potential of geological or waste materials, particularly in the context of acid mine drainage or acid sulfate soils. It typically involves determining total sulfur or sulfide sulfur concentrations as a proxy for potential acidity, and measuring carbonate or other neutralizing mineral contents to estimate neutralization potential. These parameters are combined, often as net acid producing potential (NAPP) and net neutralization potential (NNP), to classify materials as potentially acid-forming, non-acid-forming, or uncertain, thereby informing management, remediation, and regulatory decisions.
Relatively simple habitat management can influence population genetics, providing conservation managers with the opportunity to support genetic resilience not only through breeding programs or translocations, but also by ...

Many people have probably seen birds picking up small pieces of man-made materials, like strips of a plastic bag or paper litter, and taking them into their nest. This behavior appears to be fairly widespread among birds. ...
A new study from North Carolina State University identifies vertebrate hemoglobin in bone extracts from two dinosaurs and shows that this molecule is original to those animals. The work also shows how heme, a small molecule ...
