Divergent Genetic Pathways Underlying Convergent Parasitic Behaviours in Blowflies

open access: yesMolecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT Blowfly (Diptera: Calliphoridae) exhibit diverse feeding strategies, with most species developing on decomposing organic matter. However, parasitism has evolved within the family, and some species convergently gained the ability to explore the tissues of living vertebrate hosts, which imposes critical veterinary, medical, and agricultural ...

ECTOPARASITISM AS A CAUSE OF NATAL DISPERSAL IN CLIFF SWALLOWS [PDF]

open access: yes, 1992
Nestling Cliff Swallows (Hirundo pyrrhonota) in southwestern Nebraska that were relatively heavily parasitized by hematophagous fleas (Ceratophyllus celsus) and swallow bugs (Oeciacus vicarius) dispersed to nonnatal colonies to breed the subsequent year,

Spotless starlings prefer spotless eggs: conspecific brood parasites cue on eggshell spottiness to avoid ectoparasites

open access: yes, 2020
Avian brood parasites are expected to select host nests according to characteristics that maximize offspring fitness, such as reduced probability of ectoparasitism.

Ectoparasite Presence, Density, And Unit Load In Relation To Tent-roosting Behavior Of Neotropical Bats [PDF]

open access: yes, 2009
Behavioral defenses have evolved in response to the negative effects caused by ectoparasitism. Within neotropical bats, roosting behaviors have been studied as a possible reaction to the presence of parasitic bat flies and mites. Tent-making, the process

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 ...

Phentolamine Infusion for the Treatment of Norepinephrine Extravasation in a Dog

open access: yesJournal of Veterinary Emergency and Critical Care, Volume 35, Issue 2, Page 156-161, March/April 2025.
ABSTRACT Objective To describe a case of clinically significant norepinephrine extravasation in a dog with a successful outcome following the use of subcutaneous phentolamine infusion. Case Summary An 8‐year‐old male neutered Labrador Retriever experienced norepinephrine extravasation from a cephalic, peripheral intravenous catheter while under ...

Influence of seasonal and edaphic factors on the diversity of scolopendromorph centipedes (Chilopoda: Scolopendromorpha) and general observations on their ecology from Kerala, India

open access: yesJournal of Threatened Taxa, 2017
Scolopendromorph centipedes (Chilopoda: Scolopendromorpha) are a diverse group of invertebrate communities, which play significant, but often poorly acknowledged or understood roles in the delivery of soil ecosystem services.

Hair fragility (trichorrhexis nodosa) in alopecic Pomeranian dogs

open access: yesVeterinary Dermatology, Volume 36, Issue 1, Page 64-73, February 2025.
Background – Alopecia associated with hair cycle arrest (HCA, Alopecia X) is well‐recognised in Pomeranian dogs. The authors are unaware of reports of hair fragility in affected dogs. Hypothesis/Objectives – Following the observation of frequent hair shaft abnormalities in alopecic Pomeranians, we hypothesised that hair fragility events would be more ...

Costs of Franklin’s ground squirrel (Poliocitellusfranklinii) ectoparasitism reveal adaptive sex allocation [PDF]

open access: yes, 2017
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

Pet and Stray Dogs’ Contribution to Zoonotic Transmission Pathways: A Bibliometric Review

open access: yesTransboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Based on a large‐scale bibliometric dataset, domestic dogs (Canis lupus familiaris) emerge as the most frequently cited host species in the context of zoonoses, being mentioned in at least 10% of publications for nearly a quarter of the pathogens recognized as zoonotic to humans.
