The Supercooling Responses of the Solitary Bee Osmia excavata (Hymenoptera: Megachilidae) under the Biological Stress of Its Brood Parasite, Sapyga coma (Hymenoptera: Sapygidae) [PDF]
Insects, 2022 (1) Background: Many insects have evolved different strategies to adapt to subzero temperatures and parasites, but the supercooling response of pollinator populations under the brood parasitism pressure has not been sufficiently investigated. (2) Methods:

The overlooked complexity of avian brood parasite–host relationships [PDF]
Ecology Letters, 2022 The relationships between avian brood parasites and their hosts are widely recognised as model systems for studying coevolution. However, while most brood parasites are known to parasitise multiple species of host and hosts are often subject to ...

The ghosts of parasitism past: lingering frontline anti-brood parasite defenses in a former host. [PDF]
Environmental Epigenetics, 2021 Coevolutionary arms races between brood parasites and hosts provide tractable systems for understanding antagonistic coevolution in nature; however, little is known about the fate of frontline antiparasite defenses when the host “wins” the coevolutionary

Coevolution in action: disruptive selection on egg colour in an avian brood parasite and its host. [PDF]
PLoS ONE, 2010 Trait polymorphism can evolve as a consequence of frequency-dependent selection. Coevolutionary interactions between hosts and parasites may lead to selection on both to evolve extreme phenotypes deviating from the norm, through disruptive selection.Here,

PLoS ONE, 2020 The fitness and virulence of parasites is often determined by how many resources they can wrangle out of their hosts. Host defenses that help to keep resources from the parasites will then reduce virulence and parasite fitness.

Diet specialization and brood parasitism in cuckoo species [PDF]
Ecology and Evolution, 2020 Brood parasitism is a breeding strategy adopted by many species of cuckoos across the world. This breeding strategy influences the evolution of life histories of brood parasite species.

Gayana, 2023 The Screaming Cowbird (Molothrus rufoaxillaris) is a brood-parasite specialized in parasitizing the Grayish Baywing (Agelaioides badius). Recently, it started to parasite a new host, the Austral Blackbird (Curaeus curaeus), which has driven the ...

Persistence, Seasonal Dynamics, and Regional Differentiation of the Parasitic Mite Tropilaelaps mercedesae in Apis mellifera L. Colonies Under Non-Endemic Climatic Conditions [PDF]
InsectsTropilaelaps mercedesae is an emerging parasite of Apis mellifera L. that is expanding beyond its traditional tropical range, yet its ecology in temperate regions remains poorly understood.

Personality of hosts and their brood parasites [PDF]
Current Zoology, 2021 AbstractBrood parasites such as the common cuckoo Cuculus canorus exploit the parental abilities of their hosts, hosts avoid brood parasitism and predation by showing specific behavior such as loss of feathers, emission of fear screams and contact calls, displaying wriggle behavior to avoid hosts or potential prey, pecking at hosts and prey, and ...

Defences against brood parasites from a social immunity perspective [PDF]
, 2019 Parasitic interactions are so ubiquitous that all multicellular organisms have evolved a system of defences to reduce their costs, whether the parasites they encounter are the classic parasites which feed on the individual, or brood parasites which usurp
