sweepstakes dispersal,*sweepstakes dispersal route* A term coined by G. G. Simpson [1] in 1940 to describe a possible route of faunal interchange which is unlikely to be used by most .

Next, we investigated the importance of collective dispersal for detecting sweepstake signatures. We simulated a generalized scenario involving five populations . Overview. sweepstakes route. Quick Reference. A potential migration pathway along which species disperse with difficulty. Chance events play a large role in .Passive wind dispersal is sometimes called "sweepstakes dispersal" because its chance of success is so low, just like a lottery or horse race sweepstakes. Another problem with this method is that most of the .

Next, we investigated the importance of collective dispersal for detecting sweepstake signatures. We simulated a generalized scenario involving five populations . A clade’s evolutionary history is shaped, in part, by geographical range expansion, sweepstakes dispersal and local extinction. A rigorous understanding of historical biogeography may . Abstract. Aim To investigate the validity of Simpson's model of sweepstakes dispersal, particularly as it applies to the colonization of Madagascar by African .The only viable hypotheses that remain entail sweepstakes dispersal across ma-rine barriers by early monkeys on natural rafts.sweepstakes dispersalsweepstake dispersal route. A term coined by G. G. *Simpson in 1940 to describe a possible route of faunal interchange which is unlikely to be used by most animals, but .Here, we study their biogeographic history of continental dispersal events and test whether these are associated with increases in lineage diversification. LOCATION: Asia, India, .

While sweepstakes dispersal, based on irregular, stochastic opportunities, predicts a random model of colonization, Figure 1 indicates a more constrained pattern. The iguanas (Opluridae) and river turtles (Podecnemididae) are likely to have been present on the Gondwanan supercontinent, alongside the extinct Cretaceous fauna (gondwanatheres .

Aim To investigate the validity of Simpson's model of sweepstakes dispersal, particularly as it applies to the colonization of Madagascar by African mammals. We chose lemurs as a classic case. Location The East African coast, the Mozambique Channel and Madagascar.. Methods First, we investigated the assumptions underlying . sweepstake a form of gambling, especially on horse races, in which all the stakes are divided among the winners; the word originally (from the late 14th century) meant someone who ‘sweeps’, or takes the whole of, stakes in a game; in figurative usage, someone who took or appropriated everything. From the 15th to the 17th century, .The only viable hypotheses that remain entail sweepstakes dispersal across marine barriers by early monkeys on natural rafts. Early anthropoids and certain Asian rodent clades seem to have been especially adept at accomplishing sweepstakes dispersal, particularly during the Eocene, although this process has classically been envisioned as .Instead, our analyses reconstruct a southeast Asian origin of the entire clade and independent dispersal events to other continents by snakeheads, anabantids, and spiny eels, with no signal of elevated lineage diversification occurring after these invasions. . Dispersal sweepstakes: biotic interchange propelled air breathing fishes across the .sweepstake dispersal route. A term coined by G. G. *Simpson in 1940 to describe a possible route of faunal interchange which is unlikely to be used by most animals, but which will, by chance, be used by some. It requires a major barrier that is occasionally crossed.

Three scenarios consider different dispersal routes: (1) stepping-stones; (2) single-step; and (3) sweepstakes. Finally, three vectors of dispersion are considered: (1) birds; (2) wind; and (3) floating islands. Evaluation of these scenarios suggests that early-branching lineages of Asteraceae probably dispersed from South America to Africa .Sweepstakes dispersal by various terrestrial mammal clades, especially rodents and primates, was facilitated by Eocene greenhouse climatic conditions, which promoted extreme precipitation events and frequent flooding of major river drainages. Keywords: Eocene Omomyidae Sweepstakes dispersal Pontides Orhaniye Basin Turkey 1. .Writing in 1915, before the recent denials of the existence of centers of dispersal, Matthew took these as universally admitted. . If a sweepstakes route exists, it depends on chance whether a given type of animal that can cross it will really do so, which of two types of animals will cross first, and when any particular types will cross it. . Next, we investigated the importance of collective dispersal for detecting sweepstake signatures. We simulated a generalized scenario involving five populations including a “source” and a “sink” population. Reproduction in the source population followed the sweepstake model described above, with F = 1, K = 1000, and St = 10 .sweepstake dispersal route. A term coined by G. G. *Simpson in 1940 to describe a possible route of faunal interchange which is . Access to the complete content on Oxford Reference requires a subscription or purchase.

sweepstakes dispersal, particularly during the Eocene, although this process has classically been envisioned as highly random and extremely rare. This article identifies and discusses biological and geological factors that make sweepstakes dispersal by certain taxa at given times far less random than previously conceived. 199

Here, we study their biogeographic history of continental dispersal events and test whether these are associated with increases in lineage diversification.Asia, India, Africa freshwater habitats.Synbranchiformes (gouramis, snakeheads, swamp eels, and relatives).We used nearly 1000 ultra‐conserved elements (UCEs) and . Successful “sweepstakes dispersal” , which carries seeds across oceans, may occur once during the course of a species’ lifespan. Sweepstakes dispersal can be inferred from DNA sequence phylogeography and molecular clock methods . If the genetic divergence between disjunct populations is much less than expected under the time . Much like island colonization , explicit modelling of sweepstakes dispersal in addition to range expansion may be more appropriate for continental-level biogeographic analyses, especially in deep time. Furthermore, the fact that analyses employing a geologically reasonable time-stratified adjacency matrix failed to run under DEC owing to .

We would like to show you a description here but the site won’t allow us. Consistently, studies have shown that species with high dispersal potential (planktonic larval dispersal >2 weeks) usually display high temporal genetic instability of populations, because of .
