Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

Integrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

Integrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Late Holocene moisture variability in Arctic Alaska from chitin δ18O

Boreas, EarlyView.
Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

Modelling the monthly abundance of Culicoides biting midges in nine European countries using Random Forests machine learning

Parasites & Vectors, 2020
Culicoides biting midges transmit viruses resulting in disease in ruminants and equids such as bluetongue, Schmallenberg disease and African horse sickness.

Monitoring of Putative Vectors of Bluetongue Virus Serotype 8, Germany

Emerging Infectious Diseases, 2009
To identify the vectors of bluetongue virus (BTV) in Germany, we monitored Culicoides spp. biting midges during April 2007–May 2008. Molecular characterization of batches of midges that tested positive for BTV suggests C.

“CONSCIENCE AND THE ENDS OF HUMANITY: CHRISTIAN HUMANISM AND ARTIFICIAL INTELLIGENCE”

Modern Theology, EarlyView.
Abstract The astonishing speed of the development of Artificial Intelligence (AI) has sparked reflections by theologians and philosophers on what distinctiveness, if any, human beings possess as individuals and as a species. This article addresses this question with respect to an ancient idea in Christian thought reaching back to St.

Impact of Gut Bacteria on the Infection and Transmission of Pathogenic Arboviruses by Biting Midges and Mosquitoes

Microbial Ecology, 2020
Tripartite interactions among insect vectors, midgut bacteria, and viruses may determine the ability of insects to transmit pathogenic arboviruses. Here, we investigated the impact of gut bacteria on the susceptibility of Culicoides nubeculosus and ...

Feeding Site Specificity in Frog-biting Midges (Corethrellidae)

Journal of Insect Behavior, 2022
AbstractHematophagous arthropods often choose predictable feeding sites on their hosts´ body, presumably to maximize blood uptake while minimizing costs. Feeding sites can be host-specific, mediated by intrinsic host characters and/or specific preferences of the blood feeder. We investigated feeding site specificity in a community of frog-biting midges

Investigation of the global transportation of Culicoides biting midges, vectors of livestock and equid arboviruses, from flower‐packing plants in Kenya

Medical and Veterinary Entomology, EarlyView.
Arboviral diseases spread by Culicoides biting midges have been introduced into Europe by unknown means. A possible route is the carriage of midges with cut flowers shipped to flower markets. We sampled Culicoides in and around a cut flower farm in Kenya; midges were caught in the vicinity and a greenhouse, but not where flowers are processed.
