Extinction in population dynamics [PDF]
Physical Review E, 2004 We study a generic reaction-diffusion model for single-species population dynamics that includes reproduction, death, and competition. The population is assumed to be confined in a refuge beyond which conditions are so harsh that they lead to certain extinction.

Experimental evolution of a pheromone signal
Ecology and Evolution, 2022 Sexual signals are important in speciation, but understanding their evolution is complex as these signals are often composed of multiple, genetically interdependent components.

Interactions With Plant Defences Isolate Sympatric Populations of an Herbivorous Mite
Frontiers in Ecology and Evolution, 2022 Host plant specialisation can promote evolutionary divergence between herbivore populations associated with different plant species. While the mechanisms by which specialist species exploit their hosts have been studied widely across taxa, less is known ...

BMC Public Health, 2020 Background Of all lifestyle behaviours, smoking caused the most deaths in the last century. Because of the time lag between the act of smoking and dying from smoking, and because males generally take up smoking before females do, male and female smoking ...

Population Dynamics in River Networks [PDF]
Journal of Nonlinear Science, 2019 Natural rivers connect to each other to form networks. The geometric structure of a river network can significantly influence spatial dynamics of populations in the system. We consider a process-oriented model to describe population dynamics in river networks of trees, establish the fundamental theories of the corresponding parabolic problems and ...

A Dynamical Model for Human Population [PDF]
Proceedings of the National Academy of Sciences, 1974 We analyze a simple, deterministic model of the dynamics of population changes in a bisexual, reproductive system based on marriage. Our model is one of a general class, special cases of which have been previously discussed within the framework of population biology by D. G. Kendall, L. A. Goodman, J. H. Pollard, and others.

Juvenile Spider Mites Induce Salicylate Defenses, but Not Jasmonate Defenses, Unlike Adults
Frontiers in Plant Science, 2020 When plants detect herbivores they strengthen their defenses. As a consequence, some herbivores evolved the means to suppress these defenses. Research on induction and suppression of plant defenses usually makes use of particular life stages of ...

Stratification in health and survival after age 100: evidence from Danish centenarians
BMC Geriatrics, 2021 Background The existence of a super-select group of centenarians that demonstrates increased survivorship has been hypothesized. However, it is unknown if this super-select group possesses similar characteristics apart from extreme longevity.
