Ecological and Evolutionary Drivers of Geographic Variation in Species Diversity (2015, unknown): “…hypothesis have suggested that recent glaciation events cannot serve as a general explanation for the latitudinal diversity gradient (Mittelbach et al. 2007), because strong latitudinal diversity gradients have been reported from paleontological studies much farther back in time (e.g., Crame 2001).”
Seasonality, the latitudinal gradient of diversity, and Eocene insects (2010, background): “Tournaisian brachiopods show a steep latitudinal diversity gradient, but this becomes extremely shallow later in the Carboniferous (Dinantian, Namurian) (Raymond et al. 1989; Kelley et al. 1990; Crame 2001).”
Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography. (2007, background): “Recently, Jablonski et al. (2006) Review and Synthesis Evolution and the latitudinal gradient 323 Ó 2007 Blackwell Publishing Ltd/CNRS examined the combined effects of origination and extinction rates, plus shifts in taxon range limits, in a global analysis of marine bivalve genera over the past 11 ”
How can a knowledge of the past help to conserve the future? Biodiversity conservation and the relevance of long-term ecological studies (2007, background): “Throughout Earth’s history, there has always been a latitudinal cline in diversity and, similar to present, the low latitudes and in particular the tropical rainforests have harboured the greatest taxonomic diversity (Crame 2001; Willis & McElwain 2002).”
Evolution and diversity of the benthic fauna of the Southern Ocean continental shelf (2004, background): “Such faunas, which were not necessarily continuous through time, show two consistent features: they are invariably less diverse than their lower latitude counterparts (Crame 2001), and they are characterized by bipolar elements (Shi & Grunt 2000).”
Incumbency, diversity, and latitudinal gradients (2008, background): “However, the LDG has been at least a semi-permanent feature of the marine biosphere for much of the geologic past and seems to have been present in something like its current form not just in the Neogene, but since the Mesozoic breakup of Pangaea (Crame 2001, 2002), though evidently with a lower slo”
Why are there so many species in the tropics? (2013, background): “…of the tropics’ dynamics and phylogenetic niche conservatism of lineages can be reconciled with the fact that the LDG is an ancient pattern, reflecting a steady-state relationship to climate dating back hundreds of millions of years (e.g. Stehli et al., 1969; Crane & Lidgard, 1989; Crame, 2001).”
