Biogeography, first published in 1983, is one of the most comprehensive text and general reference books in the natural sciences. The fifth edition builds on the strengths of previous editions to provide an insightful and integrative explanation of how geographic variation across terrestrial and marine environments has influenced the fundamental processes of immigration, extinction, and evolution to shape species distributions and nearly all patterns of biological diversity. It is an empirically and conceptually rich text that illustrates general patterns and processes using examples from a broad diversity of life forms, time periods and aquatic and terrestrial ecosystems. Biogeography, Fifth Edition, is written as a primary text for undergraduate and graduate courses, and is also an invaluable reference for biogeographers, ecologists, evolutionary biologists, and conservation biologists. Its fundamental assertion is that patterns in biological diversity make little sense unless viewed within an explicit geographic context. Starting from principal patterns and fundamental principles, and assuming only a rudimentary knowledge of biology, geography, and Earth history, the text explains the relationships between geographic variation in biological diversity and the geological, ecological, and evolutionary processes that have produced them. The use of color illustrations, evaluated and optimized for colorblind readers, has transformed our abilities to illustrate key concepts and empirical patterns in the geography of nature. By providing a description of the historical development of biogeography, evolution and ecology, along with a comprehensive account of the principal patterns, fundamental principles and recent advances in each of these fields of science, our ultimate vision is for Biogeography to serve as the centerpiece of a one- or two-semester core course in biological diversity.
The acquisition of evidence pertaining to island syndrome often relies on opportunistic observations, yet prior researchers have gradually compiled a body of examples that collectively shed light on its occurrence patterns and dynamics. Our comprehensive literature review revealed that island syndrome dominantly occurs in angiosperms on oceanic islands, with a notable abundance of taxa exhibiting high endemism and possessing functional traits associated with facultative and generalized biotic interactions. While acknowledging the influence of unequal research interest and sampling efforts on the observed patterns, deviations from prevailing sampling biases evident in global plant databases and herbarium collections lend credence to genuine differences in the occurrence of island syndrome. The disproportionate incidence of island syndrome, delineated by taxonomic groups, traits, and specific islands, can be ascribed to the distinct biogeography of oceanic islands and the presence of idiosyncratic ecological and evolutionary processes that contribute to its development. Within an evolutionary framework, our overarching hypothesis posits island syndrome as a transformative trajectory away from the diverse strategies adopted by mainland plants to the alternative strategies exhibited on islands due to their isolation and ecological simplicity. This perspective fosters a more holistic perspective, encompassing the myriad and graded responses of plants to evolutionary pressures encountered on islands. Rather than dismissing the biased occurrence patterns in the examples of island syndrome, we contend that their underlying insights hold substantial value in formulating a general, mechanistic model that enhances our understanding of the development of island syndrome and its evolutionary implications.
In 2015, we called upon our colleagues to address a glaring oversight of a potentially transformative frontier in biogeography \u2013 the geography of sound (Lomolino et al. 2015). Our purpose here is to lay the conceptual foundations, based on the fundamental unifying principles of biogeography, to guide the development of the nascent field of sonoric geography. We define sonoric geography as an emerging subdiscipline of biogeography that attempts to discover and articulate patterns of geographic variation in the acoustic properties of biological communities and identify the underlying, causal explanations for those patterns.
We see at least two major benefits to this initiative. First, it will advance the field of biogeography by expanding the spectrum of biological properties studied \u2013 demonstrating how the field\u2019s fundamental, unifying principles can be applied to a novel component of biological diversity \u2013 sound and acoustic assemblages across the principal geographic dimensions (area, isolation, elevation/depth, and latitude). Second, a research program in sonoric geography will, in synergism, advance the fields of soundscape ecology (Pijanowski et al. 2011, Slabbekoorn 2018) and acoustic ecology (Wrightson 2000) by integrating an explicit geographic context into their conceptual foundations, empirical investigations, and applications for conserving biological diversity, sensu lato\u2014again, all this guided by the fundamental unifying principles of biogeography.
Whether the species-area curve (rather than the mere qualitativerelation) has any empirical support remains a matter of contention.[60] In the 1950s, Preston was a strong advocate of the power law modelwhich he believed to be the result of a dynamic equilibrium of theexchange of species between isolated habitat patches.[61] (The same idea had been worked out in some detail much earlier byMunroe but did not receive any attention.)[62] Preston's work was extended by MacArthur and Wilson to construct thetheory of island biogeography.[63] According to this theory, the number of species in islands with thesame habitat (at the same latitude) depends only on the size of theisland and its isolation. There is a dynamic equilibrium in the sensethat this number does not change over time though there is a turnoverof species which changes the composition of the community.[64] The equilibrium is supposed to be a result of a balance betweenimmigration and extinction. The immigration rate varies inversely withthe degree of isolation while the extinction rate decreases witharea. Thus, this theory incorporates the second mechanism for thespecies-area relation mentioned in the last paragraph. While someinitial experimental evidence seemed to support the theory, by themid-1970s its status had become controversial.[65]
The Lomolino model (SSlomolino) isAsym/(1 + slope^log(xmid/area)) (Lomolino 2000, Dengler 2009).Parameter Asym is the asymptotic maximum number of species,slope is the maximum slope of increase of richness, andxmid is the area where half of the maximum richness isachieved.
