aEstimates of current and future extinction rates suggest that we will lose double-digit percentages of the existing species on the Earth in this century 现在和未来绝种率的估计建议我们在地球上将丢失现有的种类的双数字百分比在本世纪[translate]
Phylogenies are used to estimate rates of speciation and extinction, reconstruct historical diversification scenarios, and link these to ecological and evolutionary factors, such as climate or organismal traits. Recent models can now estimate the effects of binary, multistate, continuous, and biogeographic...

[66,67]. In this case, greater rates of molecular evolution could lead to faster development of reproductive isolation during periods of isolation, leading to a greater average rate of speciation [68,69]. Alternatively, higher substitution rates could reduce extinction rates by accumulating more ...
Molecular phylogenies are increasingly being used to investigate the patterns and mechanisms of macroevolution. In particular, node heights in a phylogeny can be used to detect changes in rates of diversification over time. Such analyses rest on the assumption that node heights in a phylogeny represen...
monitored for 3Â years postrelease. We first predicted population growth and probability of extinction assuming no temporal variation in vital rates, then compared projections to those obtained when temporal variation was estimated with uniform priors or wit...
In contrast to ecological studies, where increased sampling effort leads to more reliable diversity estimates, the proportion of erroneous singletons in HTS studies is expected to approach 100% asymptotically with increased sequencing depth, even with low (1%) error rates25. Apart from the direct di...
because the survey uses the presence or absence of species to monitor changes in populations. Including false positives in the analysis, if not accounted for, can produce a serious bias in these population estimates. USGS has published on how to handle false positives and false negatives in asses...
