Nonlinear effects of temperature on mosquito parasite infection across a large geographic climate gradientNARA Subscribed
Temperature drives ectothermic host–parasite interactions, making them particularly sensitive to climatic variation and change. To isolate the role of temperature, lab‐based studies are increasingly used to assess and forecast disease risk under current and future climate conditions. However, in the field, the effects of temperature on parasitism may be mediated by other sources of variation, including local adaptation of host...
A Scoping Review of Mosquito Vector Range Shifts: Widespread Expansions and Evidence Gaps in Climate AttributionNARA Subscribed
As global temperatures rise, concerns about shifting mosquito ranges—and accompanying changes in the transmission of malaria, dengue, and other diseases—are mounting. However, systematic evidence for climate‐driven changes in mosquito ranges remains limited. We conducted a scoping review following PRISMA ‐ ScR guidelines of studies documenting expansions or contractions in medically important mosquito species. In total, 178 st...
How Much Warming Can Mosquito Vectors Tolerate?NARA Subscribed
Climate warming is expected to substantially impact the global landscape of mosquito‐borne disease, but these impacts will vary across disease systems and regions. Understanding which diseases, and where within their distributions, these impacts are most likely to occur is critical for preparing public health interventions. While research has centered on potential warming‐driven expansions in vector transmission, less is known...
A vector's susceptibility and ability to transmit a pathogen—termed vector competency—determines disease outcomes, yet the ecological factors influencing tick vector competency remain largely unknown. Ixodes pacificus , the tick vector of Borrelia burgdorferi ( Bb ) in the western U.S., feeds on rodents, birds, and lizards. Rodents and birds are reservoirs for Bb and infect juvenile ticks, while lizards are refractory to Bb an...
Multiyear drought exacerbates long‐term effects of climate on an invasive ant speciesNARA Subscribed
Invasive species threaten biodiversity, ecosystem function, and human health, but the long‐term drivers of invasion dynamics remain poorly understood. We use data from a 28‐yr ongoing survey of a Northern California ant community invaded by the Argentine ant ( Linepithema humile ) to investigate the influence of abiotic and biotic factors on invasion dynamics. We found that the distribution of L . humile retracted following an...
Vector‐borne diseases (VBDs) are embedded within complex socio‐ecological systems. While research has traditionally focused on the direct effects of VBDs on human morbidity and mortality, it is increasingly clear that their impacts are much more pervasive. VBDs are dynamically linked to feedbacks between environmental conditions, vector ecology, disease burden, and societal responses that drive transmission. As a result, VBDs...
Lyme disease is the most common vector‐borne disease in temperate zones and a growing public health threat in the United States (US). The life cycles of the tick vectors and spirochete pathogen are highly sensitive to climate, but determining the impact of climate change on Lyme disease burden has been challenging due to the complex ecology of the disease and the presence of multiple, interacting drivers of transmission. Here...
