Severe population collapses and species extinctions in multihost epidemic dynamics.
Most infectious diseases, including more than half of known human pathogens, are not restricted to just one host, yet much of the mathematical modeling of infections has been limited to a single species. We investigate consequences of a single epidemic propagating in multiple species and compare and contrast it with the endemic steady state of the disease. We use the two-species susceptible-inf...
متن کاملOverfishing causes frequent fish population collapses but rare extinctions.
Burgess et al.’s report in PNAS, “Range contraction enables harvesting to extinction” (1), provides a highly valuable perspective on the consequences of species range contractions that maintain local densities of declining populations. The authors suggest that this densitydependent contraction maintains local harvesting yields and economic incentives that enable depleted natural populations of ...
متن کاملPerpetual integrals convergence and extinctions in population dynamics
In this article we use a criterion for the integrability of paths of onedimensional diffusion processes from which we derive new insights on allelic fixation in several situations. This well known criterion involves a simple necessary and sufficient condition based on scale function and speed measure. We provide a new simple proof for this result and also obtain explicit bounds for the moments ...
متن کاملAsymmetric disease dynamics in multihost interconnected networks.
Epidemic spread in single-host systems strongly depends on the population's transmission network. However, little is known regarding the spread of epidemics across networks representing populations of multiple hosts. We explored cross-species transmission in a multilayer network where layers represent populations of two distinct hosts, and disease can spread across intralayer (within-host) and ...
