Amblyomma cajennense Sensu Stricto (Fabricius, 1787) and Amblyomma sculptum (Berlese, 1888) Tick Saliva Elicit Immune‐Modulatory Activity in Isolated Murine Macrophages With an Insight Into Proteomic Analysis

Parasite Immunology, Volume 48, Issue 3, March 2026.
ABSTRACT Tick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.). The impact of saliva from these species on murine macrophages remains unclear.

Development and Characterization of Microsatellite Genetic Markers for Hyalomma rufipes, a Tick Vector of Crimean‐Congo Hemorrhagic Fever Virus

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study developed and validated 14 polymorphic microsatellite markers to investigate the population genetics of Hyalomma rufipes, a tick species that transmits Crimean‐Congo Hemorrhagic Fever Virus (CCHFV) in East Africa. Ticks collected from livestock in northern Kenya were morphologically and genetically identified, followed by genome sequencing ...

Forest harvest and natural stressors compound to reduce juvenile ungulate survival

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
Anthropogenic disturbances, such as forest harvest, create risky landscapes for juveniles by increasing their vulnerability to predation and hunting, and when combined with natural stressors like parasitism, likely drive population declines. Managing landscapes with a species‐centric approach that addresses the cumulative effects of human and natural ...

Predation vs. Parasitism: A Case Study of Indigenous Co‐Stewardship and Science Co‐Production to Measure Temporal Shifts in Moose Mortality on Ancestral Lands of the Grand Portage Ojibwe

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study, led by the Grand Portage Band of Lake Superior Chippewa, tracks survival and examines causes of adult moose mortality from 2010 to 2022 on the Grand Portage Indian Reservation and in Voyageurs National Park. Using a Bayesian framework, we integrated multiple contributing factors to accurately estimate cause‐specific mortality probabilities ...

Geographical distribution of Dermacentor marginatus and Dermacentor reticulatus in Europe

Ticks and Tick-borne Diseases, 2016
The goal of this paper is to present up-to-date maps depicting the geographical distribution of Dermacentor species in Europe based on georeferenced sampling sites. Therefore, a dataset was compiled, resulting in 1286 D. marginatus (Sulzer, 1776) and 1209 D. reticulatus (Fabricius, 1794) locations.
