Mosquito Host Selection Varies Seasonally with Host Availability and Mosquito Density [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2011
Host selection by vector mosquitoes is a critical component of virus proliferation, particularly for viruses such as West Nile (WNV) that are transmitted enzootically to a variety of avian hosts, and tangentially to dead-end hosts such as humans. Culex tarsalis is a principal vector of WNV in rural areas of western North America. Based on previous work,

Chemical cues mediating aphid location by natural enemies

open access: yesEuropean Journal of Entomology, 2008
There is increasing evidence that chemical cues play a pivotal role in host selection by the natural enemies of aphids. We use Vinson's (1976) division of the host selection process into habitat location, host location and host acceptance for both ...

Planets spinning up their host stars: a twist on the age-activity relationship

open access: yes, 2013
It is a long-standing question in exoplanet research if Hot Jupiters can influence the magnetic activity of their host stars. While cool stars usually spin down with age and become inactive, an input of angular momentum through tidal interaction, as seen

Plant Host-Associated Mechanisms for Microbial Selection

open access: yesFrontiers in Plant Science, 2019
Plants serve as host to numerous microorganisms. The members of these microbial communities interact among each other and with the plant, and there is increasing evidence to suggest that the microbial community may promote plant growth, improve drought ...

Host Plant Specialization Driven by Sexual Selection [PDF]

open access: yesThe American Naturalist, 2007
We propose a new mechanism based on sexual selection to explain the evolution of diet breadth in insects. More specifically, we show that mate choice in females for certain diet-derived male pheromones can be exploited by maternal effect genes that preferentially place offspring on a specific host plant, resulting in specialization.

The role of multilevel selection in host microbiome evolution

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance All animals carry microbes that can affect their health by providing essential nutrients or other services. There is an active debate about how hosts and their microbes coevolve.
