Diet specialization and brood parasitism in cuckoo species [PDF]

open access: yesEcology 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.

Rare insights into intraspecific brood parasitism and apparent quasi–parasitism in black–capped chickadees [PDF]

open access: yesAnimal Biodiversity and Conservation, 2011
Genetic analysis of passerine birds often finds evidence of extra–pair copulations within species, but genetic evidence of intraspecific brood parasitism (IBP) and quasi–parasitism (Q–P) are relatively rare. Further, it is even rarer for genetic patterns

Red‐winged blackbirds nesting nearer to yellow warbler and conspecific nests experience less brood parasitism [PDF]

open access: yesEcology and Evolution, 2023
In functionally referential communication systems, the signaler's message intended for a conspecific receiver may be intercepted and used by a heterospecific eavesdropper for its own benefit. For example, yellow warblers (Setophaga petechia) produce seet

Model eggs fail to detect egg recognition in host populations after brood parasitism is relaxed [PDF]

open access: yesFrontiers in Zoology, 2020
Background Obligate brood parasites exert strong selective pressure on target hosts. In response, hosts typically evolve anti-parasitism strategies, of which egg recognition is one of the most efficient.

Importance of cooperation: How host nest defenses effectively prevent brood parasitism from the cuckoos [PDF]

open access: yesiScience, 2023
Summary: As the frontline defense against avian brood parasitism, nest defense is important in reducing nest parasitism and increasing host fitness.

Individual experience as a key to success for the cuckoo catfish brood parasitism [PDF]

open access: yesNature Communications, 2022
The importance of learning for brood parasites is explored using cuckoo catfish. The catfish increase their parasitism success as they gain experience, mainly by improving their social coordination and timing of intrusions to cichlid host spawnings.

Beyond genes‐for‐behaviour: The potential for genomics to resolve long‐standing questions in avian brood parasitism [PDF]

open access: yesEcology and Evolution
Behavioural ecology by definition of its founding ‘Tinbergian framework’ is an integrative field, however, it lags behind in incorporating genomic methods. ‘Finding the gene/s for a behaviour’ is still rarely feasible or cost‐effective in the wild but as

Avian brood parasitism in Italy: another perspective

open access: yesAvocetta, 2020
We present a quantitative analysis of the data reported in the only published review of parasitism frequency on hosts of Common Cuckoo Cuculus canorus in a Mediterranean area. We first eliminated a bias potentially introduced by the method by which data

Corallorhiza striata is the first example of a pseudocopulatory orchid in North America and an instance of "double deception" in fully mycoheterotrophic plants. [PDF]

open access: yesAm J Bot
Abstract Premise Orchids have many pollination strategies, from highly species‐specific mutualisms with insects to deceit pollination, including sexual deception. The family also has the most leafless, parasitic species (mycoheterotrophs) of any plant family.

Conventional oil and natural gas infrastructure increases brown-headed cowbird (Molothrus ater) relative abundance and parasitism in mixed-grass prairie [PDF]

open access: yesRoyal Society Open Science, 2017
The rapid expansion of oil and natural gas development across the Northern Great Plains has contributed to habitat fragmentation, which may facilitate brood parasitism of ground-nesting grassland songbird nests by brown-headed cowbirds (Molothrus ater ...
