Culver Climatic and tectonic drivers shaped the tropical distribution of coral reefs. . Differential extinction and the contrasting structure of polar marine faunas. The end-Permian extinction, closure of lapetus, together with warming, appears to have set in motion an unparalleled, explosive, gymnosperm radiation; whilst the Late Triassic extinction dramatically curtailed it. - 194.249.1.182.

Geology Science The distribution of biodiversity in the 5 My after the mass extinction event was characterized by a flat gradient, with no tropical peak, which is critical to determining which . Early attempts to construct diversity curves through time and space were based on literal readings of the fossil record, with numbers of taxa summed for each temporal or spatial bin. Nat. Although Laurentia is more diverse than the other palaeocontinents both before and after the boundary, the magnitude of this difference is increased during the glaciation, as a result of higher origination rates and increased dispersal into tropically buffered Laurentia. S. extinction, invasion, and extirpation components of the brachiopod latitudinal biodiversity gradient through the Phanerozoic Eon. J.E. Evolution (1987) 42-50 Perspectiva Mundial sobre Diversidad Biolgica. Sampling-mediated diversity of Late OrdovicianEarly Silurian invertebrate genera for three palaeocontinents (which existed before the formation of the supercontinent Pangaea, which later fragmented to form the present-day continents), shown on a Late Ordovician palaeogeographic reconstruction and plotted against geological time. Global patterns and predictors of marine biodiversity across taxa. K. Evol., 29 (2014), pp. Scotese (eds) Palaeozoic Palaeogeography and Biogeography, Geol. (1997) . A phylogeny of one productidine clade demonstrates that many lineages contracted, rather than expanded, their ranges over time. Consequently, support for the cradle and museum hypotheses, or some combination of them, is controversial. Population divergence in plant species reflects latitudinal diversity gradients. 2006 Oct 6;314(5796):102-6. doi: 10.1126/science.1130880. However, the latitudinal gradient does not correspond simply with the precipitation gradient that is responsible for a concomitant reduction in biodiversity. (1960) A dynamic null model for latitudinal gradients of species diversity. 61 7076 Marine Zoogeography . Subsampling methods enable comparisons of taxonomic richness between samples of different sizes through the simulation of uniform sample size (i.e., sample-based rarefaction; The quality of the fossil record and the accuracy of phylogenetic inferences about sampling and diversity.

The bimodal LDG likely emerged before the Anthropocene and industrialization, and perhaps 15,000 y ago, indicating a strong environmental control of tropical diversity even before the start of anthropogenic warming, however, model projections suggest that future Anthropogenic warming further diminishes tropical pelagic diversity to a level not seen in millions of years. ArticleTitleAspect diversity in moths: a temperate-tropical comparison Using both paleontological and distributional data, we compare the origination, extinction and immigration levels between low and high latitudes since the earliest proliferation of the group during the midTriassic . 6481, K.W. Proc. The latitudinal biodiversity gradient through deep time. Fischer It is suggested that the latitudinal diversity gradient clearly recognised today, where species richness increases towards the tropics, may have been partly reversed during phases of Hot House climate. 2022 Jun 24;73(12):4079-4093. doi: 10.1093/jxb/erac149.

The results suggest that the modern-day LBG on land was only established 30 million years ago, following a significant post-Eocene recalibration, potentially related to increased seasonality. Spatial species-richness gradients across scales: a meta-analysis. Occurrence Crocodilian diversity in space and time: the role of climate in paleoecology and its implication for understanding K/T extinctions. we present first results from the latitudinal HAUSGARTEN gradient, consisting of three different stations (N3, HG-IV, S3) between 7830N and 7945N (2351-2788 m depth), obtained . Veizer J.W. J. Linnean Soc. Biological Reviews, 2013. Out of the tropics: evolutionary dynamics of the latitudinal diversity gradient. 1013, K. After mediating for biases in fossil record sampling, a tropical biodiversity peak is only recognised during intervals of the Palaeozoic and the past 30myr (, There are numerous avenues for further exploration of the evolution of the LBG.

The latitudinal biodiversity gradient (LBG), in which species richness increases from the poles to tropical regions, is one of the most pervasive biodiversity patterns today. Biodivers.
