Temperature is a poor proxy for synergistic climate forcing of plankton evolution
- Environmental Science, GeographyProceedings of the Royal Society B: Biological Sciences
- 2018
The results caution against the use of a ‘silver bullet’ environmental parameter to represent global climate while studying evolutionary responses to abiotic change, and show that more comprehensive reconstruction of palaeobiological dynamics requires multiple biotic and abiotic dimensions.
A positive relationship between functional redundancy and temperature in Cenozoic marine ecosystems
- Environmental ScienceScience
- 2021
There is a positive relationship between the number of species in an area, theNumber of ecological functional groups, and oceanic temperature in the shallow-marine fossil record of New Zealand over a time span of ~40 million years, revealing a long-lived and persistent association between the spatial structuring of biodiversity, the temperature-dependence of functional redundancy, and shallow- marine biodiversity in mid-latitudes.
A twofold role for global energy gradients in marine biodiversity trends
- Environmental Science
- 2015
Marine systems break some of the confounding correlations among temperature, latitude and biodiversity that typify the terrestrial systems, and suggest that ecological specialization underlies the similarly high diversities in the shallow tropics and deep sea.
Evolutionary history and its relevance in understanding and conserving southern African biodiversity

Abstract :
Understanding how biodiversity is distributed is central to any conservation effort and has traditionally been based on niche modeling and the causal relationship between spatial…
Loss of Biodiversity Dimensions through Shifting Climates and Ancient Mass Extinctions.
- Environmental Science, GeographyIntegrative and comparative biology
- 2018
The fossil record raises a key issue: whether the biotic consequences of present-day stresses will more closely resemble the long-term effects of past climate changes or those that cascaded from the mass extinctions.
Shaping the Latitudinal Diversity Gradient: New Perspectives from a Synthesis of Paleobiology and Biogeography
- Environmental Science, GeographyThe American Naturalist
- 2017
It is argued that many of the most dramatic biotic patterns, past and present, are likely to have been generated by diverse, mutually reinforcing drivers.
What causes latitudinal gradients in species diversity? Evolutionary processes and ecological constraints on swallowtail biodiversity.
- Environmental ScienceEcology letters
- 2012
The latitudinal diversity gradient (LDG) observed in swallowtail butterflies is caused by climatically driven changes in both clades based on evidence of responses to cooling and warming events, and distinct biogeographical histories constrained by tropical niche conservatism and niche evolution.
Diversity in neotropical wet forests during the Cenozoic is linked more to atmospheric CO2 than temperature
- Environmental Science, GeographyProceedings of the Royal Society B: Biological Sciences
- 2013
Pollen morphospecies richness in an angiosperm-dominated record from the Palaeogene and early Neogene of Colombia and Venezuela correlates positively to CO2 much more strongly than to temperature, a prediction supported by analyses if productivity is linked to species richness.
A model for global diversity in response to temperature change over geological time scales, with reference to planktic organisms.

Biodiversity tracks temperature over time
- Environmental ScienceProceedings of the National Academy of Sciences
- 2012
This work analyzes marine invertebrate biodiversity patterns for the Phanerozoic Eon while controlling for sampling effort to suggest a convergence of global scale macroevolutionary and macroecological pattern for the biodiversity-temperature relationship.

Ecological and Evolutionary Responses to Recent Climate Change
- Environmental Science
- 2006
Range-restricted species, particularly polar and mountaintop species, show severe range contractions and have been the first groups in which entire species have gone extinct due to recent climate change.
A long-term association between global temperature and biodiversity, origination and extinction in the fossil record
- Environmental Science, GeographyProceedings of the Royal Society B: Biological Sciences
- 2007
Global biodiversity (the richness of families and genera) is related to temperature and has been relatively low during warm ‘greenhouse’ phases, while during the same phases extinction and origination rates of taxonomic lineages have been relatively high.
Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography.
- Environmental Science, GeographyEcology letters
- 2007
Two major hypotheses for the origin of the latitudinal diversity gradient are reviewed, including the time and area hypothesis and the diversification rate hypothesis, which hold that tropical regions diversify faster due to higher rates of speciation, or due to lower extinction rates.
Assessing latitudinal gradients in speciation rates and biodiversity at the global scale.
- Environmental ScienceEcology letters
- 2006
It is shown for the first time that latitudinal biodiversity gradients exhibit strong positive correlations with speciation rates even after explicitly controlling for variation in sampling effort and for increases in habitat area towards the equator, providing compelling evidence that geographical variation in macroevolutionary dynamics is a primary determinant of contemporary biodiversity gradient, as predicted by dispersal-assembly theory.
Evidence for a Time‐Integrated Species‐Area Effect on the Latitudinal Gradient in Tree Diversity
- Environmental ScienceThe American Naturalist
- 2006
This work correlates estimates of current tree species diversity with a composite parameter integrating area over geological time for each continent’s tropical, temperate, and boreal biomes and finds significant positive correlations between current tree diversity and area‐time for periods since the Eocene, Oligocene, and Miocene.

It is often claimed that we do not understand the forces driving the global diversity gradient. However, an extensive literature suggests that contemporary climate constrains terrestrial taxonomic…
The tropics as a source of evolutionary novelty through geological time
- Environmental ScienceNature
- 1993
A new palaeontological analysis of post-Palaeozoic marine orders shows significantly more first appearances in tropical waters, whether defined latitudinally or biogeographically, than expected from sampling alone, providing direct evidence that tropical regions have been a major source of evolutionary novelty, and not simply a refuge that accumulated diversity owing to low extinction rates.
Climate, energy and diversity

It is concluded that there is no single species/energy mechanism; fundamentally different processes link energy to abundance in plants and animals, and diversity is affected secondarily.
The road from Santa Rosalia: A faster tempo of evolution in tropical climates
- BiologyProceedings of the National Academy of Sciences of the United States of America
- 2006
Test the prediction by K. Rohde that the tempo of molecular evolution in the tropics is greater than at higher latitudes and found the relationship continued to hold for genera with the same number of, or more, species in temperate latitudes, suggesting that greater rates of speciation in the Tropics do not cause higher rates of Molecular evolution.
The Species Richness-Energy Hypothesis in a System Where Historical Factors Are Thought to Prevail: Coral Reefs
- Environmental ScienceThe American Naturalist
- 1996
A relationship between coral richness and up-current island density that is consistent with vicariance models of speciation and theories of coral dispersal is found, and little evidence is found supporting other ecological hypotheses, including the hypotheses that disturbance or environmental stability is an important control of diversity.
