Species diversityRelationships between species diversity and other species-density and species-richness metrics were investigated in the seagrass macrobenthos of Knysna estuarine bay, South Africa. Although a wide range of species density occurred across sites, neither Hill-Shannon nor Hill-Simpson ...

Overfitting: When an AI model becomes too tuned into the training data sets, it can lock into those specifics rather than being capable of handling diversity and surprises. That phenomenon is known as “overfitting,” and it prevents accurate predictions in the future. An example of overfitting...
More than a half-century ago, the ‘cognitive revolution’, with the influential tenet ‘cognition is computation’, launched the investigation of the mind through a multidisciplinary endeavour called cognitive science. Despite significant diversity of views regarding its definition and intended scope, th...
Not only do the destructive actions of humans have the potential to erode our quality of life in the long term, but their ripple effects could eventually upend our success as a species, according to Ceballos. “When we lose genera, we’re losing more genetic diversity, we’re losing more ...
