Volatiles of symbiotic bacterial origin explain ectoparasitism and fledging success of hoopoes [PDF]
Animal MicrobiomeBackground Some parasites use olfactory cues to detect their hosts and, since bacterial symbionts are partially responsible for animal odours, they could influence host parasitism.

Chigger mite (Eutrombicula alfreddugesi) ectoparasitism does not contribute to sex differences in growth rate in eastern fence lizards (Sceloporus undulatus) [PDF]
Ecology and Evolution, 2023 Parasitism is nearly ubiquitous in animals and is frequently associated with fitness costs in host organisms, including reduced growth, foraging, and reproduction.

Prevalence of Ectoparasitism on Small Ruminants in Kelantan, Malaysia. [PDF]
Trop Life Sci Res, 2020 Kelantan is a chiefly agrarian state with abundant small-holder ruminant farms in the East Coast economic Region of Malaysia. Ectoparasitism affects small ruminant production in Malaysia.

Extreme adaptations for aquatic ectoparasitism in a Jurassic fly larva [PDF]
eLife, 2014 The reconstruction of ancient insect ectoparasitism is challenging, mostly because of the extreme scarcity of fossils with obvious ectoparasitic features such as sucking-piercing mouthparts and specialized attachment organs.

International Journal for Parasitology: Parasites and Wildlife, 2015 Within many species, males are often more heavily parasitised than females. Several hypotheses have been proposed to explain this phenomenon, including immunocompetence handicaps, sexual size dimorphism and behavioural differences.

British Red Squirrels (S. vulgaris) With Leprosy Develop Skeletal Lesions [PDF]
Interdisciplinary Perspectives on Infectious Diseases, Volume 2026, Issue 1, 2026.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.

Ectoparasitism and the gut microbiota: a cross-fostering experiment in a wild passerine. [PDF]
FEMS Microbiol EcolThe gut microbiota plays a key role in host development, physiology, and immunity, and is likely shaped by hosts’ genetic and environmental factors, including ectoparasitism and, thus, host health. Here, we experimentally manipulated ectoparasite (Carnus

Amblyomma sculptum ticks on a giant otter from the Brazilian Pantanal [PDF]
Revista Brasileira de Parasitologia Veterinária, 2023 The giant otter (Pteronura brasiliensis) is a semiaquatic carnivore and a top predator in the trophic chain, considered a sentinel of freshwater ecosystems. Ticks are common ectoparasites of worldwide distribution and potential vectors of diseases.

Ectoparasitism shortens the breeding season in a colonial bird [PDF]
Royal Society Open Science, 2015 When blood-feeding parasites increase seasonally, their deleterious effects may prevent some host species, especially those living in large groups where parasites are numerous, from reproducing later in the summer. Yet the role of parasites in regulating

The role of southern red-backed voles, Myodes gapperi, and Peromyscus mice in the enzootic maintenance of Lyme disease spirochetes in North Dakota, USA [PDF]
Ticks and Tick-Borne DiseasesLyme disease has expanded into the Great Plains of the USA. To investigate local enzootic transmission, small mammals were trapped in two forested tracts in northeastern North Dakota during 2012 and 2013.
