Biodiversity and Biogeography
As we have seen, life has been important in shaping its own environment throughout its 3.8 Ga* geologically recorded history. It has influenced earth-surface temperatures (Classes 2, 9, 10) through its involvement in the geochemical cycles that determine the world oceans salt content and the atmospheres composition (Classes 7-10). Overall, lifes effects have tended to compensate for the ther...
متن کاملThe Cladid Crinoid Barycrinus from the Burlington Limestone (early Osagean) and the Phylogenetics of Mississippian Botryocrinids
All species of Barycrinus from the early Osagean Burlington Limestone of the United States midcontinent are reviewed. Burlington Barycrinus species include: B. rhombiferus (Owen and Shumard, 1852); B. magister (Hall, 1858); B. spurius (Hall, 1858); B. crassibrachiatus (Hall, 1860); B. scitulus (Meek and Worthen, 1860) n. combination; and B. sampsoni Miller and Gurley, 1896. Cyathocrinus latus H...
متن کاملEvolutionary significance of differential species longevity in Osagean–Meramecian (Mississippian) crinoid clades
—The pattern of differential species longevities among five Osagean–Meramecian crinoid clades is analyzed for its evolutionary significance. Differences in mean species longevity between clades may have resulted from species sorting based on eurytopy (niche breadth). In order to test the relationship between longevity and eurytopy it was first necessary to recognize generalists (eurytopes) vs. ...
متن کاملBiodiversity and biogeography of the atmosphere
The variation of life has predominantly been studied on land and in water, but this focus is changing. There is a resurging interest in the distribution of life in the atmosphere and the processes that underlie patterns in this distribution. Here, we review our current state of knowledge about the biodiversity and biogeography of the atmosphere, with an emphasis on micro-organisms, the numerica...
متن کاملPYCNOIB: Biodiversity and Biogeography of Iberian Pycnogonids
Biodiversity and biogeographic studies comparing the distribution patterns of benthic marine organisms across the Iberian Atlantic and Mediterranean waters are scarce. The Pycnogonida (sea spiders) are a clear example of both endemicity and diversity, and are considered a key taxon to study and monitor biogeographic and biodiversity patterns. This is the first review that compiles data about ab...
