A population biology perspective on the stepwise infection process of the bacterial pathogen Pasteuria ramosa in Daphnia

D Ebert, D Duneau, MD Hall, P Luijckx, JP Andras… - Advances in …, 2016 - Elsevier
The infection process of many diseases can be divided into series of steps, each one
required to successfully complete the parasite's life and transmission cycle. This approach …

Long-term balancing selection for pathogen resistance maintains trans-species polymorphisms in a planktonic crustacean

L Cornetti, PD Fields, L Du Pasquier, D Ebert - Nature Communications, 2024 - nature.com
Balancing selection is an evolutionary process that maintains genetic polymorphisms at
selected loci and strongly reduces the likelihood of allele fixation. When allelic …

Metschnikowia: half tetrads, a regicide and the fountain of youth

MA Lachance - Yeast, 2016 - Wiley Online Library
The purpose of this review is to introduce Metschnikowia to the yeast researcher community

Within-host priority effects systematically alter pathogen coexistence

PA Clay, K Dhir, VHW Rudolf… - The American …, 2019 - journals.uchicago.edu

evolution. Because pathogens compete for limiting resources, whether multiple pathogens …

Out of the 'host'box: extreme off-host conditions alter the infectivity and virulence of a parasitic bacterium

E Marcus, T Dagan, W Asli… - … Transactions of the …, 2023 - royalsocietypublishing.org

Red Queen dynamics in multi-host and multi-parasite interaction system

JF Rabajante, JM Tubay, T Uehara, S Morita… - Scientific Reports, 2015 - nature.com
In host-parasite systems, dominant host types are expected to be eventually replaced by
other hosts due to the elevated potency of their specific parasites. This leads to changes in …

Predators and patterns of within-host growth can mediate both among-host competition and evolution of transmission potential of parasites

SKJR Auld, SR Hall, J Housley Ochs… - The American …, 2014 - journals.uchicago.edu
Parasite prevalence shows tremendous spatiotemporal variation. Theory indicates that this
variation might stem from life-history characteristics of parasites and key ecological factors …

Variation in costs of parasite resistance among natural host populations

S Auld, RM Penczykowski… - Journal of …, 2013 - academic.oup.com
Organisms that can resist parasitic infection often have lower fitness in the absence of
parasites. These costs of resistance can mediate host evolution during parasite epidemics …

Context-dependent host-symbiont interactions: Shifts along the parasitism-mutualism continuum

MA Rogalski, T Stewart Merrill… - The American …, 2021 - journals.uchicago.edu
Symbiotic interactions can shift along a mutualism-parasitism continuum. While there are
many studies examining dynamics typically considered to be mutualistic that sometimes shift …

Population‐level effects of parasitism on a freshwater ecosystem engineer, the unionid mussel Anodonta anatina

JI Brian, SE Dunne, CL Ellis, DC Aldridge - Freshwater Biology, 2021 - Wiley Online Library
Parasites can negatively affect hosts at individual, population, and species‐level scales.
However, the link between individual‐and population‐level impacts is often poorly …
