Evaluation of the murine immune response to Xenopsylla cheopis flea saliva and its effect on transmission of Yersinia pestis.

open access: yesPLoS Neglected Tropical Diseases, 2014
Background/aimsArthropod-borne pathogens are transmitted into a unique intradermal microenvironment that includes the saliva of their vectors. Immunomodulatory factors in the saliva can enhance infectivity; however, in some cases the immune response that

Impact of Environmental Microparticles on Insect Olfaction

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Comparing the Effects of Microplastics From Conventional Cigarette Butts and Heated Tobacco Device: The Role of UV‐Induced Aging

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Despite the widespread presence of cigarette butts in the environment, the potential toxicological effects posed by microplastics (MPs) derived from them remain poorly understood. In this study, we compared the effects of MPs from conventional cigarette butts (cellulose acetate) and heated tobacco devices (cellulose acetate and polylactic acid

Relationships between functional alpha and beta diversities of flea parasites and their small mammalian hosts

open access: yesParasitology
We studied the relationships between functional alpha and beta diversities of fleas and their small mammalian hosts in 4 biogeographic realms (the Afrotropics, the Nearctic, the Neotropics and the Palearctic), considering 3 components of alpha diversity (

Interactions between prairie dogs and arthropods in grassland ecosystems: a review and research gaps

open access: yesWildlife Biology, EarlyView.
Prairie dogs (Cynomys spp.) are an important component of grassland ecosystems of North America where they can alter vegetation composition/structure and physical attributes of grassland habitats through their feeding and burrowing behavior. Impacts of prairie dog presence on many wildlife and plant taxa have been widely studied but research on prairie

Introgressed Brassica napus × Sinapis alba enhance resistance to the crucifer flea beetle (Phyllotreta cruciferae). [PDF]

open access: yesPest Manag Sci
This study demonstrates that Brassica napus lines with Sinapis alba introgressions enhanced resistance against Phyllotreta cruciferae, resulting in reduced feeding damage and improved seedling physiological performance. The introgressed lines showed strong potential as genetic resources for developing more resilient and sustainable canola varieties ...

From landscapes to lesions: Pathology's role in wildlife mortality investigations and conservation health

open access: yesWildlife Society Bulletin, EarlyView.
Wildlife mortality investigations are important toward understanding health threats to wildlife and management considerations. The who, what, why and how are critical pieces of these investigations. Wildlife pathologists play a central role in this process in elucidating causes and contributors to mortality. Abstract To effectively recognize and manage
