The contribution of nonecological factors to global patterns in diversity is evident when species richness differs between regions with similar habitats and geographic area. Mangrove environments in the Eastern Hemisphere harbor six times as many species of trees and shrubs as similar environments in the New World. Genetic divergence of mangrove lineages from terrestrial relatives, in combination with fossil evidence, suggests that mangrove diversity is limited by evolutionary transition into…

High tropical net diversification drives the New World latitudinal gradient in palm (Arecaceae) species richness
TLDR
The geographical patterns in palm species richness appear to be predominantly the result of elevated net diversification rates towards the equator and in warm, wet climates, sustained throughout most of the Tertiary.
Recent assembly of the Cerrado, a neotropical plant diversity hotspot, by in situ evolution of adaptations to fire
TLDR
These findings imply that the Cerrado formed in situ via recent and frequent adaptive shifts to resist fire, rather than via dispersal of lineages already adapted to fire, and add to growing evidence that the origins and historical assembly of species-rich biomes have been idiosyncratic.
Explaining disparities in species richness between Mediterranean floristic regions: a case study in Gladiolus (Iridaceae)
TLDR
The results suggest that regions at comparable latitudes and/or with similar climate may not converge in diversity levels due to heterogeneity of diversification rates and contrasting biogeographical histories.
Mosaics in the mangroves: allopatric diversification of tree-climbing mudwhelks (Gastropoda: Potamididae: Cerithidea) in the Indo-West Pacific
TLDR
These allopatric mosaic distributions suggest that speciation may have been driven by isolation during low sea-level stands, during episodes preceding the Plio-Pleistocene glaciations.
Taxon recruitment of the arctic flora: an analysis of phylogenies.
The Arctic is the endpoint of many climatic gradients and is presently occupied by c. 2200 vascular plant species. Glaciation started in the Middle Eocene but a significant expansion of the Greenland…
Energy and the tempo of evolution in amphibians
TLDR
The consistency of these results with the previous studies that used quite different organisms – and in this instance also using different genes – suggests that this is a ubiquitous pattern in nature consistent with the predictions of the ESH.
Mangroves: A Global Perspective on the Evolution and Conservation of Their Terrestrial Vertebrates
Mangrove ecosystems are found globally along tropical and subtropical coastlines. They exhibit a steep environmental gradient between inland and marine systems, providing a unique, selective…
Phylogeographic pattern of Rhizophora (Rhizophoraceae) reveals the importance of both vicariance and long-distance oceanic dispersal to modern mangrove distribution
TLDR
This study demonstrates that neither vicariance nor dispersal alone could explain the observed global occurrences of Rhizophora, but a combination of vicariant events and oceanic long-distance dispersals can account for historical diversification and present-day biogeographic patterns of mangroves.
Clade Age and Diversification Rate Variation Explain Disparity in Species Richness among Water Scavenger Beetle (Hydrophilidae) Lineages
TLDR
Diversification in water scavenger beetles (Hydrophilidae), which vary in species richness among major lineages by as much as 20 fold, is investigated and it is found that Amphiopini, an old clade, is significantly more species poor than expected, possibly due to its restricted geographic range.
History and Diversity: Explorations at the Intersection of Ecology and Evolution

TLDR
The ecological interactions between populations within regions brings the timescale of species sorting and species production close to each other and emphasizes the important interaction of ecological and evolutionary processes in shaping ecological systems.

Origins of mangrove ecosystems and the mangrove biodiversity anomaly
TLDR
Patterns of nestedness at the community and species-level both point towards three independent regions of diversification of mangrove ecosystems: South-east Asia, the Caribbean and Eastern Pacific, and the Indian Ocean region.
Large-scale processes and the Asian bias in species diversity of temperate plants
TLDR
The most probable cause of the EAS-ENA anomaly in diversity is the extreme physiographical heterogeneity of temperate eastern Asia, especially compared with eastern North America, which in conjunction with climate and sea-level change has provided abundant opportunities for evolutionary radiation through allopatric speciation.
Mangrove vegetation: an evolutionary perspective
TLDR
There are several historical and modern processes which in combination, have resulted in the present day distribution of mangroves, which is analysed particularly in relation to regions of endemism, vicariance among species, discontinuous distributions, hybridization and divergence.
Evolutionary diversification and the origin of the diversity-environment relationship.
TLDR
To assess the relative roles of local ecological constraint vs. regional and historical unfolding of diversity-environment relationships, ecologists must abandon localized concepts of the community and adopt historical and geographic methods to evaluate the evolution of diversity within large regions and its influence on diversity at local scales.
ABSOLUTE DIVERSIFICATION RATES IN ANGIOSPERM CLADES
TLDR
The phylogenetic distribution of clades with an exceedingly high number of species suggests that traits that confer high rates of diversification evolved independently in different instances and do not characterize the angiosperms as a whole.
Global patterns of tree species richness in moist forests : energy-diversity theory does not account for variation in species richness.
TLDR
Evidence is presented that the number of tree species on 26 large areas of moist temperate forest show continental differences unrelated to geographical patterns in evapotranspiration, and that likewise cannot be attributed to eeoeraohi.
Diversification of Gulf/Caribbean Mangrove Communities through Cenozoic Time1
  • A. Graham

TLDR
The fossil record identifies a trend of increasing diversity that can be assessed as new assemblages are studied, and provides a first quantitative estimate of Neotropical history through the Cenozoic Era.
Historical biogeography, ecology and species richness.
Introduction and synthesis: Plant phylogeny and the origin of major biomes.
TLDR
Dated plant phylogenies for angiosperm families indicate that long-distance, transoceanic dispersal has played an important role in shaping their distributions, and that this can obscure any effect of tectonic history.
Community Diversity: Relative Roles of Local and Regional Processes
TLDR
Observations suggest that regional and historical processes, as well as unique events and circumstances, profoundly influence local community structure and ecologists must broaden their concepts of community processes and incorporate data from systematics, biogeography, and paleontology into analyses of ecological patterns and tests of community theory.
