Megjegyzések:	Experimentation is at the heart of classical and modern behavioral ecologyresearch. The manipulation of natural cues allows us to establish causa-tion between aspects of the environment, both internal and external toorganisms, and their effects on animals' behaviors. In recognition systemsresearch, including the quest to understand the coevolution of sensorycues and decision rules underlying the rejection of foreign eggs by hosts ofavian brood parasites, artificial stimuli have been used extensively, butnot without controversy. In response to repeated criticism about the valueof artificial stimuli, we describe four potential benefits of using them inegg recognition research, two each at the proximate and ultimate levels ofanalysis: (1) the standardization of stimuli for developmental studies and(2) the disassociation of correlated traits of egg phenotypes used for sensory discrimination, as well as (3) the estimation of the strength of selection on parasitic egg mimicry and (4) the establishment of the evolved limits of sensory and cognitive plasticity. We also highlight constraints ofthe artificial stimulus approach and provide a specific test of whetherresponses to artificial cues can accurately predict responses to naturalcues. Artificial stimuli have a general value in ethological research beyondresearch in brood parasitism and may be especially critical in field studiesinvolving the manipulation of a single parameter, where other, confoundingvariables are difficult or impossible to control experimentally or statistically.

Cím:	Multiple parasitism reduces egg rejection in the host (Acrocephalus arundinaceus) of a mimetic avian brood parasite (Cuculus canorus). / Manna Thomas J., Moskát Csaba, Tong Lainga, Bán Miklós, Aidala Zachary, Low, Jason, Hauber Márk E.

Megjegyzések:	A host that has been targeted by an avian brood parasite can recover most of its potential fitness loss by ejecting the foreign egg(s) from its nest. The propensity for some hosts to engage in egg rejection behavior has put selective pressure on their parasites to evolve mimetic eggshells resembling the host's own shell colors and maculation. In turn, hosts have counterevolved increasingly more sophisticated detection methods such as narrowing visual egg acceptance thresholds or using social cues to recognize parasitism. However, multiple cognitive mechanisms acting simultaneously could theoretically interfere with one another and ultimately decrease egg rejection accuracy, especially if these heuristics yield differing targets for rejection. By painting hosts own eggs, we studied a host species of the common cuckoo Cuculus canorus, the great reed warbler Acrocephalus arundinaceus, and tested its responses to the presence of "foreign" eggs of varying quantity, colors, and uniformity. Using reflectance spectra of egg background coloration and avian perceptual modeling, we then estimated the sensory thresholds triggering egg rejection by this host for each treatment. As previously reported, rejection rates were positively related to the perceptual distance between own and foreign eggs in the nests in all treatments. However, rejection thresholds were more permissive (error prone) both with greater proportions of foreign eggs per clutch and/or when the suite of foreign eggs was perceptually more variable within the nest. These results suggest that parasites, through multiple parasitism, can partially overcome the evolution of hosts' recognition of mimetic parasite eggs.

Megjegyzések:	Egg discrimination by hosts is an antiparasitic defence to reject foreign eggsfrom the nest. Even when mimetic, the presence of brood parasitic egg(s)typically alters the overall similarity of all eggs in a clutch, producing a dis-cordant clutch compared to more homogenous clutches of composed onlyof hosts' own eggs. In multiple parasitism, the more foreign eggs are laidin the nest, the more heterogeneous the overall clutch appears. Perceptualfilters and recognition templates cannot explain the known pattern oflower rejection rates of foreign eggs in multiple vs. single parasitism. Wetherefore assessed the role of clutch homogeneity and manipulated thecolour of one or more eggs in the clutches of great reed warbler (Acroceph-alus arundinaceus) hosts of common cuckoos (Cuculus canorus). Varying thecolours of both the majority and the minority eggs caused predictableshifts in the rejection of the focal egg(s), and ejection rates of the minorityegg colour consistently increased but only when it belonged to a moremimetic egg colour, relative to the less mimetic colour of majority eggs.The results imply that in addition to sensory filters, and template-basedcognitive decision rules, discordancy-based rejection is affected by theoverall clutch appearance and interacts with specific colours varying inthe extent of mimicry, to contribute to the recognition decisions of hosts to reject parasitic eggs.
