For the first time, morpho-anatomical characters that were congruent with DNA sequence data were used to characterize several genera in Hapalidiaceae —the major eco-engineers of Subarctic carbonate ecosystems. DNA sequencing of three genes (SSU, rbcL, ribulose-1, 5-bisphosphate carboxylase/ oxygenase large subunit gene and psbA, photosystem II D1 protein gene), along with patterns of cell …
By the mid-20th century, widespread concerns were being expressed for the way in which modern human populations and their industrial endeavors and products were affecting both the environment in which they lived and the planet’s wild populations and their ecosystems. Some predictions for the future were dire, and enough environmental activism developed so that some of the more conspicuous pro…
A new species conforming to the generic description of Sporolithon was found forming small (1–3 cm in diameter) rhodoliths at 18–75 m depth on the eastern coast of Brazil. Sporolithon tenue Bahia, Amado-Filho, Maneveldt et W.H. Adey, sp. nov. differs from other species of Sporolithon in having a thin, primary vegetative thallus of only 45–250 μm in thickness composed of up to 20 cell l…
