Extinction Probabilities of Supercritical Decomposable Branching Processes [PDF]
Journal of Applied Probability, 2012 We focus on supercritical decomposable (reducible) multitype branching processes. Types are partitioned into irreducible equivalence classes. In this context, extinction of some classes is possible without the whole process becoming extinct. We derive criteria for the almost-sure extinction of the whole process, as well as of a specific class ...

On the effect of postponing pregnancy in a Zika transmission model
Advances in Difference Equations, 2021 We construct a Zika transmission model to investigate the effect of postponing pregnancy on the infection intensity. We perform analytical and numerical investigations for deterministic and stochastic analysis to obtain the basic reproductive ratio ...

Extinction risk from climate change
Nature, 2004 Climate change over the past ∼30 years has produced numerous shifts in the distributions and abundances of species and has been implicated in one species-level extinction.

Extinction probabilities as a function of temperature for populations of tsetse (Glossina spp.).
PLoS Neglected Tropical Diseases, 2020 Significant reductions in populations of tsetse (Glossina spp) in parts of Zimbabwe have been attributed to increases in temperature over recent decades. Sustained increases in temperature might lead to local extinctions of tsetse populations. Extinction

Probabilities of therapeutic extinction of HIV
Applied Mathematics Letters, 2006 Using branching process principles and recent developments in HIV immunology, a methodology is demonstrated to compute the probability of extinction of HIV in the presence of protease inhibitors.

Geosciences, 2018 We consider the effect of global warming on the coupled plankton-oxygen dynamics in the ocean. The net oxygen production by phytoplankton is known to depend on the water temperature and hence can be disrupted by warming.

Plant DiversityTall clonal grasses commonly display competitive advantages with nitrogen (N) enrichment. However, it is currently unknown whether the height is derived from the vegetative or reproductive module.

Avian Conservation and Ecology, 2022 Conservation reliant species complicate the idealized view of endangered species recovery by depending on perpetual management to maintain viable populations, making the goal of de-listing via threat removal potentially unattainable.

Epidemiological and evolutionary consequences of different types of CRISPR-Cas systems.
PLoS Computational Biology, 2022 Bacteria have adaptive immunity against viruses (phages) in the form of CRISPR-Cas immune systems. Currently, 6 types of CRISPR-Cas systems are known and the molecular study of three of these has revealed important molecular differences. It is unknown if

Shaping the extinction burst: Increasing its probability and preventing its emergence across topographies. [PDF]
J Exp Anal BehavExtinction bursts are traditionally described as transient increases in response rate following the discontinuation of reinforcement. However, their underlying mechanisms remain under debate. This study examined whether extinction bursts are modulated by
