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.

Architecture of Paradiplozoon homoion: A diplozoid monogenean exhibiting highly-developed equipment for ectoparasitism. [PDF]
PLoS ONE, 2018 Diplozoidae (Monogenea) are blood-feeding freshwater fish gill ectoparasites with extraordinary body architecture and a unique sexual behaviour in which two larval worms fuse and transform into one functioning individual.

Біологічні студії, 2022 Background. Over 700 species of ticks are characterised by moderate to high host specificity, and a handful by very high host specificity, parasitizing upon a single host species. The rest are not host specific. One of them is the castor bean tick, which

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.

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

Avian Research, 2022 Several ectoparasites parasitise nestlings decreasing their body condition, growth and survival. To minimise any loss of fitness due to ectoparasites, birds have developed a wide variety of defence mechanisms, potentially including hatching asynchrony ...

Ectoparasitism and infections in the exoskeletons of large fossil cingulates. [PDF]
PLoS ONE, 2018 Studies on paleopathological alterations in fossil vertebrates, including damages caused by infections and ectoparasites, are important because they are potential sources of paleoecological information. Analyzing exoskeleton material (isolated osteoderms,
