Conceptual issues in local adaptation
TLDR
This paper advocates multifaceted approaches to the study of local adaptation, and stresses the need for experiments explicitly addressing hypotheses about the role of particular ecological and genetic factors that promote or hinder local adaptation.

Ecology, Epidemiology, and Evolution of Parasitism in Daphnia
Virulence and Local Adaptation of a Horizontally Transmitted Parasite
TLDR
In a horizontally transmitted microparasitic disease in Daphnia, a planktonic crustacean, increasing geographic distance between host and parasite origin was found to be correlated with a decrease in spore production and virulence, which contradicts the hypothesis that long-standing coevolved parasites are less virulent than novel parasites.

Host–parasite ‘Red Queen’ dynamics archived in pond sediment
TLDR
From the moment the parasite was first found in the sediments, the authors observed a steady increase in virulence over time, associated with higher fitness of the parasite, and a coevolutionary model based on negative frequency-dependent selection corroborated these experimental results.

Experimental evolution of parasites.
TLDR
Serial passage experiments show that within-host competition generally drives an increase in a parasite's virulence in a new host, whereas the parasite becomes avirulent to its former host, indicating a trade-off between parasite fitnesses on different hosts.

Development, Life Cycle, Ultrastructure and Phylogenetic Position of Pasteuria ramosa Metchnikoff 1888: Rediscovery of an Obligate Endoparasite of Daphnia magna Straus
TLDR
Suggestions that this parasite is a bacterium are confirmed and refute its previous tentative placement based on its morphological complexity among the Actinomycetales.

The curse of the pharaoh : the evolution of virulence in pathogens with long living propagules
TLDR
For parasites that have recently invaded a susceptible host population, greater propagule longevity may initially favour higher virulence; but once the equilibrium is reached the optimal virulence is independent of propagules longevity.

The Epidemiology and Evolution of Symbionts with Mixed-Mode Transmission
TLDR
This review explores the conceptual issues surrounding the dynamics of mixedmode symbionts by reviewing literature from the entire range of host and symbiont taxa and comparing MMT with the authors' expectations for single-mode strategies.

Intensive fish farming and the evolution of pathogen virulence: the case of columnaris disease in Finland
TLDR
An increase in the occurrence of the bacterial fish disease Flavobacterium columnare in salmon fingerlings at a fish farm in northern Finland over 23 years is shown, hypothesizing that this emergence was owing to evolutionary changes in bacterial virulence.
