Spatial relatedness and brood parasitism in a female-philopatric bird
, 2008 The spatial structure of relatedness between individuals in a population can be crucial for social selection and evolution. Here we analyze a female alternative reproductive tactic, conspecific brood parasitism, in relation to spatial relatedness among ...

Agricultural and Forest Entomology, EarlyView.Twenty‐four bark beetle biocontrol programmes involving 41 natural enemy introductions are reported globally. A total of 36.6% of agents were established and 9.8% were reported effective, while many agent establishments and impacts often remained unassessed and incomparable across regions.

Do nest size and shape characteristics affect nest parasitism rates?
Wildlife Society Bulletin, 2016 Brown‐headed cowbirds (Molothrus ater) are obligate brood parasites that lay eggs in host species’ nests. Studies on effects of host nest characteristics (e.g., nest placement, concealment, nest size) on parasitism rates by brown‐headed cowbirds have ...

Larval character evolution in Holometabola (Insecta)
Cladistics, EarlyView.Abstract Larvae, a novel type of immature stage, are a crucial innovation of the Holometabola. Larval features therefore provide key evidence for reconstructing evolutionary transformations in this megadiverse group. Here we present the first formal reconstruction of larval character evolution, using maximum parsimony and Bayesian ancestral‐state ...

The importance of genetic evidence for identifying intra-specific brood parasitism
, 2006 Intra-specific brood parasitism is widespread among birds. When genetic evidence is not available, criteria like super-normal clutch size, high within-clutch variance in egg morphology, and shorter than normal laying intervals have been used to identify ...

Entomologia Experimentalis et Applicata, EarlyView.Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.

Brood parasitism and proximity to human habitation
, 2017 Humans provide safe refuge against many species such as birds of prey because such species keep a safe distance from humans. We hypothesized that many suitable host species for brood parasites similarly seek refuge in the proximity of humans to avoid ...

Timing pattern of Common Cuckoo parasitism and its relation to host nest attendance
Ibis, EarlyView.Classical works show the adaptive importance of precise timing of egg‐laying in brood parasitic Common Cuckoos Cuculus canorus to ensure sufficient incubation time and successful hatching. Laying in the late afternoon has been suggested to increase the chance of secretive parasitism and therefore escape the aggressive mobbing by hosts, yet this ...
