To assess the coextinction of species (the loss of a species upon the loss of another), we present a probabilistic model, scaled with empirical data. The model examines the relationship between coextinction levels (proportion of species extinct) of affiliates and their hosts across a wide range of coevolved interspecific systems: pollinating Ficus wasps and Ficus, parasites and their hosts, butterflies and their larval host plants, and ant butterflies and their host ants. Applying a nomographic…

Coextinction and persistence of dependent species in a changing world

Based on primary extinctions and interactions among species, network models explore extinction cascades and predict and historical evidence reveals that the threat of coextinction is influenced by both host a...

Estimates of coextinction risk: how anuran parasites respond to the extinction of their hosts.

The sixth mass coextinction: are most endangered species parasites and mutualists?

This work discusses the interactions and synergies between coextinction and other drivers of species loss, particularly climate change, and suggests the way forward for understanding the phenomenon of co Extinction, which may well be the most insidious threat to global biodiversity.

Fish parasites resolve the paradox of missing coextinctions

Analysis of the coextinction risk of 12,141 fish parasite species finds that highly specific parasites are not the most endangered, because they tend to use hosts with low vulnerability to extinction.

among island populations of an endangered species

It is found that ectoparasite attributes including diversity and intensity varied among host populations, and it is shown that knowing the parasite composition of the host can identify its population of origin, due to unique host–parasite interactions.

Biodiversity loss decreases parasite diversity: theory and patterns

In empirical food webs with random removals of free- Living species, the relationship between free-living species richness and parasite richness was, on average, quasi-linear, suggesting biodiversity loss reduces parasite diversity more than previously thought.

Managing coextinction of insects in a changing climate

The primary reason for the development of the framework was to provide adaptation actions in the face of climate change, and the framework can be used when insects require conservation action to ameliorate impacts of other threatening processes.

Current Constraints and Future Directions in Estimating Coextinction

Without synergistic development of better empirical data and more realistic models to estimate the number of cothreatened species and coextinction rates, the contribution of co Extinction to global declines in biodiversity will remain unknown and unmanaged.

Which host-dependent insects are most prone to coextinction under changed climates?

The aim of this review was to provide a platform for future research, directing efforts toward taxa and habitats at greatest risk of species loss through coextinction accelerated by climate change.

Co‐Extinctions of Tropical Butterflies and their Hostplants

This simulation shows that the number of extinct butterfly species is expected to increase exponentially with that of extinct hostplants, and suggests that the preservation of whole habitats is urgently needed if the possible cascading effects of species (co-)extinctions are to be avoided.

Environmental Changes, Coextinction, and Patterns in the Fossil Record

A new model for large scale evolution and extinction in which species are organized into food webs, which is able to reproduce the empirical observations without defining a fitness function or invoking competition between species.

Habitat fragmentation, percolation theory and the conservation of a keystone species

Many species survive in specialized habitats. When these habitats are destroyed or fragmented the threat of extinction looms. In this paper, we use percolation theory to consider how an environment…

Catastrophic extinctions follow deforestation in Singapore

Extrapolations of the observed and inferred local extinction data imply that the current unprecedented rate of habitat destruction in Southeast Asia will result in the loss of 13–42% of regional populations over the next century, at least half of which will represent global species extinctions.

Nonrandom extinction and the loss of evolutionary history.

It is estimated that the prospective extra loss of mammalian evolutionary history alone would be equivalent to losing a monotypic phylum, and the potentially severe implications of the clumped nature of threat for the loss of biodiversity are shown.

Extinction and the loss of evolutionary history.

It is shown that approximately 80 percent of the underlying tree of life can survive even when approximately 95 percent of species are lost, and that algorithms that maximize the amount of evolutionary history preserved are not much better than choosing the survivors at random.

Biodiversity: Extinction by numbers

New work documents the uneven, highly clumped distribution of vulnerable species on the Earth, and pinpoints 25 so-called ‘biodiversity hotspots’, which should enable resources for conservation to be better focused.
