Biodiversity, as a biological phenomenon, denotes the variability and complexity of life across genes, species, populations, communities, and ecosystems, including their functional traits and phylogenetic relationships. It emerges from evolutionary processes such as mutation, selection, gene flow, and drift, and is structured by ecological interactions, environmental gradients, and spatiotemporal dynamics. Biodiversity influences and reflects ecosystem functioning, stability, and resilience through mechanisms like complementarity, redundancy, and trophic interactions. It is quantitatively characterized using metrics of richness, evenness, turnover, and functional or phylogenetic diversity, and its patterns are central to understanding biogeography, ecosystem processes, and responses to environmental change.
In ecology, the principle holds that the more diverse and heterogeneous a habitat is, the more different species it supports. To promote species diversity in forests, clearings are therefore created for nature conservation ...

Most of my ecology and evolution undergraduates have never held a pair of binoculars or looked at a bug through a magnifying glass. They don't know how to use a key to identify a plant or insect, let alone why they should ...
