Multiparasitism and repeated parasitism by the great spotted cuckoo Clamator glandarius on its main host, the magpie Pica pica: effects on reproductive success, nest desertion and nest predation

open access: yesJournal of Avian Biology, 2023
Brood parasites are expected to lay only one egg per parasitized nest, as the existence of several parasitic nestlings in a brood increases competition and can lead the starvation of some of them.

Reed Warbler Hosts Do Not Fine-Tune Mobbing Defenses During the Breeding Season, Even When Cuckoos Are Rare

open access: yesFrontiers in Ecology and Evolution, 2021
Hosts of brood parasitic cuckoos often employ mobbing attacks to defend their nests and, when mobbing is costly, hosts are predicted to adjust their mobbing to match parasitism risk. While evidence exists for fine-tuned plasticity, it remains unclear why

The Supercooling Responses of the Solitary Bee Osmia excavata (Hymenoptera: Megachilidae) under the Biological Stress of Its Brood Parasite, Sapyga coma (Hymenoptera: Sapygidae)

open access: yesInsects, 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:

Evolutionary origins and patterns of diversification in animal brood parasitism

open access: yes, 2023
Brood parasitism involves the exploitation of host parental care rather than the extraction of resources directly from hosts. Although often excluded, we show that brood parasitism fits within existing frameworks of parasitic strategies, and formulate ...

Evidence for Interspecific Brood Parasite Detection and Removal in Burying Beetles

open access: yesPsyche: A Journal of Entomology, 2018
We tested whether brood parasitism could be successful between two co-occurring species of burying beetles, Nicrophorus guttula and Nicrophorus marginatus, and whether these species exhibit an adaptive response to brood parasitism by detecting and ...

An Experimental Test of Defenses Against Avian Brood Parasitism in a Recent Host

open access: yesFrontiers in Ecology and Evolution, 2021
Theoretical studies predict that hosts of avian brood parasites should evolve defenses against parasitism in a matter of decades. However, opportunities to test these predictions are limited because brood parasites rarely switch to naïve hosts.

Reproductive Strategies Change With Time in a Newly Founded Colony of Spotless Starlings (Sturnus unicolor)

open access: yesFrontiers in Ecology and Evolution, 2021
Variation in avian reproductive strategies is often studied from a comparative perspective, since even closely-related taxa differ greatly in the degree of polygyny, extra-pair paternity (EPP) or intra-specific brood-parasitism.

Generalists and specialists of brood parasitism in spider wasps (Hymenoptera: Pompilidae)

open access: yes, 2023
Based on emergence records from trap nests and naturally occurring nests, we determined the brood parasitism behaviour of Irenangelus punctipleuris (Pompilidae: Ceropalinae) for the first time and that of Dipogon (Nipponodipogon) nagasei (Pompilidae ...
