Dietary differentiation of two co‐occurring common bat species (Eptesicus nilssonii and Pipistrellus pygmaeus)

open access: yesWildlife Biology, EarlyView.
Sympatric bat species can co‐exist and avoid interspecific competition via niche differentiation e.g. diet. Detecting dietary differences can be achieved by comparing dietary niches of sympatric and allopatric populations. If dietary overlap is higher in sympatry versus allopatry, co‐occurrence may be altering the dietary niche of the species.

Biting midges and their patogens [PDF]

open access: yes, 2015
This thesis deals with biting midges of the genus Culicoides, which are tiny nematoceran insects belonging to the Diptera, and their parasites. Biting midges partake in transmissions of several parasitical organisms of various groups.

Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies

open access: yesWildlife Biology, EarlyView.
Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

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

open access: yesIntegrative 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

open access: yesIntegrative 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.

Monitoring of Putative Vectors of Bluetongue Virus Serotype 8, Germany

open access: yesEmerging 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.

Urbanization and Vector Species Shape Avian Malaria Prevalence in Mosquitoes

open access: yesIntegrative Zoology, EarlyView.
Avian malaria prevalence was assessed in two mosquito species across urban and peri‐urban habitats. No infections were detected in either species in urban areas, while a 2.53% prevalence was found in the native Culex pipiens from peri‐urban sites, highlighting the influence of urbanization on parasite transmission dynamics.

Late Holocene moisture variability in Arctic Alaska from chitin δ18O

open access: yesBoreas, 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

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

open access: yesModern 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.
