Alexander von Humboldt of course made lasting contributions to the fields of physical geography and 'biogeography' , adding to our knowledge of plants, animals, and the earth.
By using trilobite examples they push cladistic 'biogeography' beyond the typical scope because the focus is a marine taxon whose evolutionary history predates the fragmentation of Pangea.
One of his previous books on natural history, The Song of the Dodo, dealt with island 'biogeography' and endangered species.
In addition to this one method, we have DNA testing, comparative anatomy, 'biogeography' , embryology, and comparisons between molecular structures.
This result is inconsistent with the assumption of the equilibrium theory of island 'biogeography' that animal density is independent of island area.
We would like to thank Michael L. May for many helpful discussions of damselfly biology and 'biogeography' .
Chapter 3 focuses on evolution, systematics, and 'biogeography' .
The foregoing is not to say that Newton does not appreciate the fact that a phylogenetic hypothesis can be important in 'biogeography' .
So long as its shortcomings are recognized, this book has a wealth of information on the distribution and ecological 'biogeography' of birds.
The lasting contribution of the book is in its summary of avian distributions and natural history, not in the phylogenetic interpretation of speciation and 'biogeography' .
Platnick and Nelson, who introduced the concepts of cladistic 'biogeography' , required that all taxa used must occur in three or more similar areas.
Uncertainties in history, archeology, 'biogeography' , anthropology and biosystematics obscure the dates and places of the first domestication of cultivated crops.
The main subdisciplines represented in conservation biology are population genetics, population biology, landscape ecology and 'biogeography' .
No observations from the fossil record or genomics or 'biogeography' or comparative anatomy that undermine standard evolutionary thinking.
Darwin's third line of evidence came from 'biogeography' , the study of the geographic distribution of plants and animals.
Historical 'biogeography' deals with phylogenetic patterns among species and higher lineages attributable to relatively ancient events in earth history.
Nicotiana is one of the most comprehensively studied flowering plant genera with numerous studies having accumulated a large body of information concerning evolution, cytology, taxonomy and 'biogeography' .
Despite its very promising beginnings, we agree with the assessment of Nelson and Ladiges that cladistic 'biogeography' has yielded few genuinely new insights over the last twenty years.
Nothofagus, the southern beech, is a classic example of plant 'biogeography' .
She then moved to the American Museum of Natural History in New York for postdoctoral work on the systematics, 'biogeography' , and conservation of Caribbean birds.
Artists, photographers, filmmakers, kids doing nature study, 'biogeographers' , conservation biologists, and activists, as well as taxonomists, shuffle through them for the sake of beauty, curiosity, and amazement.
‘The changes [in ocean acidity] aren't huge,’ said John Guinotte, a marine 'biogeographer' at the Marine Conservation Biology Institute in Bellevue, Washington.
The existence of a clade formed by the Spanish species is supported also by 'biogeographical' data, so that these species are geographically isolated from other species.
This paper is the first in a series of studies re-describing echinoderm taxa from these 'biogeographically' important Paleozoic assemblages.
Williams et al. compare the 'biogeographic' signal in mitochondrial and nuclear DNA sequences in Indo-West Pacific starfish and snapping shrimp.
Second, the results of standard cladistic 'biogeographic' analyses, which may combine groups of different ages, cannot be unambiguously attributed to any particular cause.
Clearly, raising each unique sequence type to the level of a strain is not biologically informative as each ‘strain’ will map to a terminal branch in a phylogeny and little can be inferred 'biogeographically' or evolutionarily.
But because they do not advocate this practice, they review island biogeography and 'biogeographic' principles of reserve design in separate, widely spaced chapters.
The objective is to bring ecologists, paleontologists, geneticists, 'biogeographers' , and others together to think ambitiously and work on evolutionary problems on a broad scale.
Furthermore, trilobite faunas in the Early Cambrian were already differentiated 'biogeographically' .
