Eaten alive: cannibalism is enhanced by parasites [PDF]
Royal Society Open Science, 2015 Cannibalism is ubiquitous in nature and especially pervasive in consumers with stage-specific resource utilization in resource-limited environments. Cannibalism is thus influential in the structure and functioning of biological communities. Parasites are

On the Saturation of the Magnetorotational Instability via Parasitic Modes [PDF]
Astrophys.J.698:L72-L76,2009, 2009 We investigate the stability of incompressible, exact, non-ideal magnetorotational (MRI) modes against parasitic instabilities. Both Kelvin-Helmholtz and tearing-mode parasitic instabilities may occur in the dissipative regimes accessible to current numerical simulations.

Mathematical model of mating probability and fertilized egg production in helminth parasites [PDF]
arXiv, 2023 In the modeling of parasite transmission dynamics, understanding the reproductive characteristics of these parasites is crucial. This paper presents a mathematical model that explores the reproductive behavior of dioecious parasites and its impact on transmission dynamics.

Numerical study of a three-state host-parasite system on the square lattice [PDF]
Phys. Rev. E 83, 046102 (2011), 2010 We numerically study the phase diagram of a three-state host-parasite model on the square lattice motivated by population biology. The model is an extension of the contact process, and the three states correspond to an empty site, a host, and a parasite. We determine the phase diagram of the model by scaling analysis. In agreement with previous results,

Co-evolution of replicators and their parasites [PDF]
arXiv, 2023 The problem of evolutionary complexification of life is considered one of the fundamental aspects in contemporary evolutionary theory. Parasitism is ubiquitous, inevitable, and arises as soon as the first replicators appear, even during the prebiotic stages of evolution.

What causes the increase in aggregation as a parasite moves up a food chain? [PDF]
Journal of the Royal Society Interface, 13 (2016) 20160102, 2016 General laws in ecological parasitology are scarce. Here we evaluate data published by over 100 authors to determine whether the number of hosts in a life cycle is associated with the degree of aggregation of fish parasites at different stages. Parasite species were grouped taxonomically to produce 20 or more data points per group as far as possible ...
