Cryptic Biodiversity Abounds in Los Angeles

Cities are often perceived as biodiversity wastelands. Adding to that perception is the common result of research surveys of urban biodiversity, which often report limited and declining numbers of species (1). Concealed by that preconception, however, is the extraordinary undiscovered biodiversity that still exists, even in the most urban of environments. Much of this biodiversity … Continue reading Cryptic Biodiversity Abounds in Los Angeles
