Data from: What is behind the variation in mate quality dependent sex ratio adjustment? – A meta-analysis

Eszter Szász, László Z. Garamszegi & Balázs Rosivall
Theory predicts that parents adjust the sex ratio of their brood to the sexually selected traits of their mate because the reproductive success of sons may be more dependent on inherited paternal attractiveness than that of daughters. Empirical studies vary in terms of whether they support the theory, and this variation has often been regarded as evidence against sex ratio adjustment or has been ascribed to methodological differences. Applying phylogenetic meta-analyses, we aimed to find...

Data from: Color polarization vision mediates the strength of an evolutionary trap

Bruce A. Robertson & Gábor Horváth
Evolutionary traps are scenarios in which animals are fooled by rapidly changing conditions into preferring poor-quality resources over those that better improve survival and reproductive success. The maladaptive attraction of aquatic insects to artificial sources of horizontally polarized light (e.g. glass buildings, asphalt roads) has become a first model system by which scientists can investigate the behavioral mechanisms that cause traps to occur. We employ this field-based system to experimentally investigate 1) in which portion(s)...

Data from: Eggshell spotting pattern is related to hatching asynchrony, hematocrit value and growth of nestling great tits (Parus major)

Rita Hargitai, Márton Herényi, Gergely Nagy & János Török
Eggshell pigmentation may signal the quality of the egg, that of the female and the environment, and thus nestling development may be related to this egg trait. However, so far, few studies have investigated the relationship between eggshell pigmentation and nestling development. Our aim was to study in a partial cross-fostering experiment whether the protoporphyrin-based eggshell pigmentation (spot intensity and spot distribution) showed any significant associations with several traits related to the development of nestling...

Data from: Interspecific transfer of parasites following a range-shift in Ficedula flycatchers

William Jones, Katarzyna Kulma, Staffan Bensch, Mariusz Cichoń, Anvar Kerimov, Miloš Krist, Toni Laaksonen, Juan Moreno, Pavel Munclinger, Fred Slater, Eszter Szöllősi, Marcel E. Visser, Anna Qvarnström & Fred M. Slater
Human-induced climate change is expected to cause major biotic changes in species distributions and thereby including escalation of novel host-parasite associations. Closely related host species that come into secondary contact are especially likely to exchange parasites and pathogens. Two competing theories, the Enemy Release Hypothesis, where invading hosts escape their original parasites; and the Novel Weapon Hypothesis, where invading hosts bring new parasites that have detrimental effects on native hosts, have been described to predict...

Data from: Optimized flocking of autonomous drones in confined environments

Gábor Vásárhelyi, Csaba Virágh, Gergő Somorjai, Tamás Nepusz, Agoston E. Eiben & Tamás Vicsek
We address a fundamental issue of collective motion of aerial robots: how to ensure that large flocks of autonomous drones seamlessly navigate in confined spaces. The numerous existing flocking models are rarely tested on actual hardware because they typically neglect some crucial aspects of multirobot systems. Constrained motion and communication capabilities, delays, perturbations, or the presence of barriers should be modeled and treated explicitly because they have large effects on collective behavior during the cooperation...

Data from: Experience during development triggers between-individual variation in behavioural plasticity

Tamás János Urszán, Laszlo Zsolt Garamszegi, Gergely Nagy, Attila Hettyey, Janos Torok & Gábor Herczeg
1. Behavioural consistency within and across behaviours (animal personality and behavioural syndrome, respectively) have been vigorously studied in the last decade, leading to the emergence of ’animal personality’ research. It has been proposed recently that not only mean behaviour (behavioural type), but the environmentally induced behavioural change (behavioural plasticity) might also differ between individuals within populations. 2. While case studies presenting between-individual variation in behavioural plasticity have started to accumulate, the mechanisms behind its emergence...

Data from: Evolution of patterned plumage as a sexual signal in estrildid finches

Masayo Soma & Laszlo Zsolt Garamszegi
Colour patterns, such as bars or dots, that cover the body surface of animals are generally thought to play roles in signalling and camouflage. In birds, however, the macroscopic aspects of plumage colouration are less well understood, as past studies typically described plumage colourations by using spectrophotometric analyses. To provide insight into the evolution of plumage patterns as sexual signals, we characterised interspecific and intersexual variations in the plumage patterns of estrildid finches and tested...

Data from: MHC-mediated sexual selection on bird song: generic polymorphism, particular alleles and acoustic signals

László Z. Garamszegi, Magdalena Zagalska-Neubauer, David Canal, György Blázi, Miklós Laczi, Gergely Nagy, Eszter Szöllősi, Éva Vaskuti, János Török & Sándor Zsebők
Several hypotheses predict that the major histocompatibility complex (MHC) drives mating preference in females. Olfactory, color or morphological traits are often found as reliable signals of the MHC profile, but the role of avian song mediating MHC-based female choice remains largely unexplored. We investigated the relationship between several MHC and acoustic features in the collared flycatcher (Ficedula albicollis) a European passerine with complex songs. We screened a fragment of the class IIB 2nd exon of...

Data from: Brain size predicts behavioural plasticity in guppies (Poecilia reticulata): an experiment

Gabor Herczeg, Tamás J. Urszán, Stephanie Orf, Gergely Nagy, Alexander Kotrschal & Niclas Kolm
Understanding how animal personality (consistent between-individual behavioural differences) arises has become a central topic in behavioural sciences. This endeavour is complicated by the fact that not only the mean behaviour of individuals (behavioural type), but also the strength of their reaction to environmental change (behavioural plasticity) varies consistently. Personality and cognitive abilities are linked and we suggest that behavioural plasticity could also be explained by differences in brain size (a proxy for cognitive abilities), since...
