Kaitlyn Dawson, Katherine Maunder, Lucas Eckert, Marlene Kraml, Chloe Dean-Moore, Christopher Eckert. (in press). Viral-induced colour change reveals that Turnip Mosaic Virus infection prevalence increases with urbanization in the invasive mustart Hersperis matronalis. International Journal of Plant Sciences.
Understanding the factors that influence pathogen prevalence is essential to mitigating the negative consequences of disease. Infection prevalence should be influenced by the demography of hosts, yet tests of this general expectation from natural populations are few. Furthermore, human activity is profoundly altering the distribution and abundance of species, which may have consequences for the pathogens that are associated with them...
David Ensing, Tyler Nelson, Chandra Moffat, Lauryn Joslin, Lucas Eckert, Marlene Kraml, Christopher Eckert. (in press). Together again: the invasive mustard Hesperis matronalis suffers devastating seed predation by a recently adventive specialist weevil. BioControl.
The enemy release hypothesis predicts explosive population growth of species that invade new locations in the absence of the natural enemies that provide top-down population control in their native range. This theory underpins classical (or importation) biological control as a management technique for invasive species, and has had resounding success when prospective control agents have been subject to appropriate screening before release. Occasionally however, natural enemies have been reunited with their hosts accidentally...
Lucas Eckert, Jessica Miller, John Fitzpatrick, Sigal Balshine, Ben Bolker. (in press). Parental care drives the evolution of male reproductive accessory glands across ray-finned fishes. Evolution.
Reproductive accessory glands are organs involved in reproduction that do not directly produce or release gametes but can play crucial roles in securing reproductive success. In fishes, the two leading hypotheses about why accessory glands evolved are 1) in response to sperm competition, or 2) to facilitate parental care activities. Here, we investigate the evolutionary history of accessory glands and test these hypotheses by estimating quantitative differences in evolutionary rates... read more
Eckert et al. 2025 - EvolutionKevin Neumann, Lucas Eckert, Damaris Miranda, Andrew Kemp, Alison Bell. 2025. Collective behavior evolves independently of benthic-limnetic divergence in stickleback. Behavioral Ecology and Sociobiology.
Comparing populations across replicate environments or habitat types can help us understand the role of ecology in evolutionary processes. If similar phenotypes are favored in similar environments, parallel evolution may occur. Collective behavior, including collective movement and social networks, can play a key role in the adaptation by animals to different environments... read more
Neumann et al. 2025 – Behavioral Ecology and SociobiologyCaitlyn Synyshyn, Lucas Eckert, Adrienne McLean, Megan Cyr, Sigal Balshine. 2023. Subtle fisheries gear model differences substantially influence catch rate of an invasive fish. Fisheries Research.
When sampling wild animals, the collection methods used can impact the number, sex, size, and behaviour of individuals captured and it is important to understand these impacts when making inferences about populations. While biases between different types of sampling gear are well recognized, biases that arise from using different models of the same gear type are often not considered... read more
