Overwinter users of nest cavities affect breeding birds via nest‐dwelling ectoparasites

open access: yesEcosphere, 2023
Cavities used for avian reproduction in spring often host other organisms for roosting during winter, which should affect their microclimatic conditions and, then, the patterns of emergence of nest‐dwelling ectoparasites of birds and successful ...

Costs of Franklin’s ground squirrel (Poliocitellus franklinii) ectoparasitism reveal adaptive sex allocation

open access: yesCanadian Journal of Zoology, 2018
Parasite infestation may impose direct costs of blood, nutrient, and energy depletion, along with indirect costs of increased immune response upon hosts. We investigated how ectoparasitism influences body mass and reproduction in a free-living population

Ectoparasitism during an avian disease outbreak: An experiment with Mycoplasma-infected house finches and ticks

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2020
Hosts are typically co-parasitized by multiple species. Parasites can benefit or suffer from the presence of other parasites, which can reduce or increase the overall virulence due to competition or facilitation.

Priming for protection: inducible attachment-resistance to ectoparasitic mites in Drosophila [PDF]

open access: yesParasitology
Ectoparasites are ubiquitous and are often harmful to host fitness. Whereas protective responses to ectoparasitism in vertebrate hosts are well documented, our understanding of such defences in invertebrates remains limited.

Water boatman survival and fecundity are related to ectoparasitism and salinity stress.

open access: yesPLoS ONE, 2019
Salinity is increasing in aquatic ecosystems in the Mediterranean region due to global change, and this is likely to have an important impact on host-parasite interactions.

Dehydrating microhabitats increase mite activity and intensify ectoparasitism of Drosophila. [PDF]

open access: yesJ Comp Physiol B
Parasites interact with their host in variable environments that are often subject to water scarcity and dehydration. Drosophila fruit flies and associated ectoparasitic mites interact across a range of microhabitats, typically in decaying organic matter,

British Red Squirrels (<i>S. vulgaris</i>) With Leprosy Develop Skeletal Lesions. [PDF]

open access: yesInterdiscip Perspect Infect Dis
Leprosy, caused by Mycobacterium lepromatosis or Mycobacterium leprae, has been reported in red squirrels in Britain from Scotland to the south of England. However, there has been no attempt to determine whether lesions caused by leprosy can be detected in the skeletons of infected animals.

Benefits and Costs of Mixed-Species Aggregations in Harvestmen (Arachnida: Opiliones)

open access: yesFrontiers in Ecology and Evolution, 2022
Many animals form aggregations with individuals of the same species (single-species aggregations, SSA). Less frequently, individuals may also aggregate with individuals of other species (mixed-species aggregations, MSA).

Host-Pathogen-Vector Continuum in a Changing Landscape: Potential Transmission Pathways for <i>Bartonella</i> in a Small Mammal Community. [PDF]

open access: yesEcol Evol
This study focuses on Bartonella spp. (a Gram‐negative bacteria) in small mammals and their ectoparasites within a rainforest human‐use landscape. We found that a high proportion (40.56%) of the tested small mammals across five species and two sites carry Bartonella, with prevalence being positively correlated with aggregated ectoparasite load. Despite

Microbiota and the volatile profile of avian nests are associated with each other and with the intensity of parasitism. [PDF]

open access: yesFEMS Microbiol Ecol
Bacteria have been suggested as being partially responsible for avian nest odours and, thus, volatiles from their metabolism could influence the intensity of selection pressures due to parasites detecting olfactory cues of their hosts.
