Abstract Biogeographical transition zones are areas of overlap, replacement or partial segregation between different biotas, which sets taxa sharing similar geographical distributions as a result common evolutionary history and ecological affinities. Transition occur in few particular the world where historically contingent processes have allowed biotic elements to coexist interact. Evolutionary historical biogeographers traditionally characterized by overlap elements. More recently, authors applying track analyses detected presence nodes conflicting results cladistic biogeographic analyses. Ecological taken approach, usually quantitative methods, for example, species turnover indices analyse strength breadth zones. Some consider represent outstanding analysing principles shaping assembly, whereas others dismissed them, sometimes artificial. particularly interesting truly integrative biogeography, being natural laboratories interaction can be analysed fruitfully, especially appropriate an epistemologically grounded pluralism. A coherent conceptual framework zones, however, is still lacking.

Abstract The Andean mountains stand out for their striking species richness and endemicity that characterize many emblematic Neotropical clades distributed in or around these mountains. radiation of the Sigmodontinae subfamily, most diversified mammalian group Neotropics, has been historically related to orogenesis. We aim evaluate this interplay between geological processes biological responses through diversification dynamics, biogeographical history, range evolution subfamily. For these, we built comprehensive phylogeny gathered 14,836 occurrences identified one shift speciation rate genus Akodon , which suffered after arrival non-Andean ancestors. Our biogeographic analyses show multiple dispersal paths throughout allowed subfamily colonize all Neotropics. Northern Andes Central-Southern were important sources diversity. In addition, relevant sink, receiving highest number lineages. region exhibited higher turnover rates than regions. Thus, our results support crucial role Mountains radiation, acting as a "macroevolutionary cradle" "species attractor" several sigmodontine lineages at different times, pump" becoming source widely neotropical Then, complex macroevolutionary dynamics would explain rodents' high extant diversity wide distribution

Amphibian Speciation Rates Support a General Role of Mountains as Biodiversity Pumps

The American Naturalist, Год журнала: 2021, Номер 198(3), С. E68 - E79

AbstractContinental mountain areas cover <15% of global land surface, yet these regions concentrate >80% terrestrial diversity. One prominent hypothesis to explain this pattern proposes that high diversities could be explained by higher diversification rates in topographic complexity (HTC). While speciation mountains has been detected for particular clades and regions, the extent which lineages experience faster remains unknown. Here we addressed issue using amphibians as a model system (>7,000 species), found families showing contain proportion species distributed mountains. Moreover, inhabiting HTC speciate than occupying are topographically less complex. When comparing across identified same five biogeographical realms where associated with levels complex topography. Low-magnitude differences between some low topographies suggest diversity is also affected extinction and/or colonization rates. Nevertheless, our results bolster importance engines at different geographical scales highlight their conservation biodiversity.

Research on land‐use evolution and ecosystem services value response in mountainous counties based on the SD‐PLUS model

Ecology and Evolution, Год журнала: 2022, Номер 12(10)

Rapid urbanization has caused changes in climate and environment threatened the ecosystem with multiple risks. The services capacity shown a downward trend accordingly. It is significant to explore spatio-temporal evolution of land use value (ESV) mountainous counties at small scales, as it coordinates economic growth ecological protection, promotes sustainable high-quality development. Based on SD-PLUS model, study simulated three scenarios land-use change Qianshan city from 2019 2035: high-growth rate, medium-growth low-growth studied impacts ESV. Results showed that: (1) Under scenarios, construction area increased significantly, forest water have decreasing trend, scale gardens partly increased. (2) In urban built-up areas, amount centrally expanded, whereas, regions, exhibits sporadic point expansion. And among various factors that influence change, impact roads all levels most significant, followed by elevation. (3) overall ESV shows rate scenario dropping least (4.91%). distribution little space scale, different regions demonstrate degrees change. From perspective type, service values conservation waste treatment are significantly reduced, while food production relatively stable; lands their ESV, cultivated remain stable. results can provide technical ideas for coordinated development protection cities boost implementation green
