Dilution effects in disease ecology

F Keesing, RS Ostfeld - Ecology Letters, 2021 - Wiley Online Library
For decades, people have reduced the transmission of pathogens by adding low‐quality
hosts to managed environments like agricultural fields. More recently, there has been …

Linked within-host and between-host models and data for infectious diseases: a systematic review

LM Childs, F El Moustaid, Z Gajewski, S Kadelka… - PeerJ, 2019 - peerj.com
The observed dynamics of infectious diseases are driven by processes across multiple
scales. Here we focus on two: within-host, that is, how an infection progresses inside a …

Breaking beta: deconstructing the parasite transmission function

H McCallum, A Fenton, PJ Hudson… - … of the Royal …, 2017 - royalsocietypublishing.org
Transmission is a fundamental step in the life cycle of every parasite but it is also one of the
most challenging processes to model and quantify. In most host–parasite models, the …

Transmission risk predicts avoidance of infected conspecifics in Trinidadian guppies

JF Stephenson, SE Perkins… - Journal of Animal …, 2018 - Wiley Online Library
Associating with conspecifics afflicted with infectious diseases increases the risk of
becoming infected, but engaging in avoidance behaviour incurs the cost of lost social …

Parasite-induced plasticity in host social behaviour depends on sex and susceptibility

JF Stephenson - Biology letters, 2019 - royalsocietypublishing.org
Understanding the effects of parasites on host behaviour, of host behaviour on parasite
infection, and the reciprocal interactions between these processes is vital to improving our …

Aggregation of symbionts on hosts depends on interaction type and host traits

DR Clark, KA Young, J Kitzes, PJ Moore, AJ Evans… - …, 2023 - Wiley Online Library
Symbionts tend to be aggregated on their hosts, such that few hosts harbor the majority of
symbionts. This ubiquitous pattern can result from stochastic processes, but aggregation …

Shoaling guppies evade predation but have deadlier parasites

JC Walsman, MJ Janecka, DR Clark… - Nature Ecology & …, 2022 - nature.com
Parasites exploit hosts to replicate and transmit, but overexploitation kills both host and
parasite. Predators may shift this cost–benefit balance by consuming infected hosts or …

The size, symmetry, and color saturation of a male guppy's ornaments forecast his resistance to parasites

JF Stephenson, M Stevens… - The American …, 2020 - journals.uchicago.edu
Sexually selected ornaments range from highly dynamic traits to those that are fixed during
development and relatively static throughout sexual maturity. Ornaments along this …

Urine DNA (uDNA) as a non‐lethal method for endoparasite biomonitoring: Development and validation

E Duval, S Blanchet, E Quéméré, L Jacquin… - Environmental …, 2021 - Wiley Online Library
Abstract Changes in environmental conditions alter host–parasite interactions, raising the
need for effective epidemiological surveillance. Developing operational, accurate, and cost …
