Food restriction delays breeding and affects insulin-like growth factor-1, oxidative damage, and haematocrit value before egg-laying in female canaries

Rita Hargitai, Nóra Boross, Zsófia Tóth & Ádám Lendvai
Environmental challenges, such as fluctuations in food availability, could influence reproductive investment. If resource availability is poor, individuals need to decide in which life-history process they invest more energy and vital compounds, which determine the cost of reproduction. In resource allocation, the physiological pathways have important roles. The aim of our study was to examine whether food availability influenced physiological traits (insulin-like growth factor-1 (IGF-1) concentration, antioxidant capacity (OXY), level of oxidative damage (ROM) and...

Data from: Foraging decisions with conservation consequences: Interaction between beavers and invasive tree species

Erika Juhász, Ákos Bede-Fazekas, Krisztián Katona, Zsolt Molnár & Marianna Biró
Herbivore species can either hinder or accelerate the invasion of woody species through selective utilization. Therefore, an exploration of foraging decisions can contribute to the understanding and forecasting of woody plant invasions. Despite the large distribution range and rapidly growing abundance of beaver species across the Northern Hemisphere, only a few studies focus on the interaction between the beaver and invasive woody plants. We collected data on the woody plant supply and utilization at 20...

Data from: White plumage color as an honest indicator: feather macrostructure links reflectance with reproductive effort and success

Miklós Laczi, Mónika Jablonszky, Gábor Markó, Gergely Nagy, Gyula Szabó, Sándor Zsebők, János Török & Gergely Hegyi
The structural condition of feathers may generally have a decisive role in shaping the color properties of the plumage. However, the information content of structurally mediated color differences is poorly known. This makes it particularly hard to determine the meaning of color variation in pigment-free white plumage patches. The white wing patch of the collared flycatcher (Ficedula albicollis) is an important sexual trait, and changes in its reflectance are partly due to macrostructural condition. We...

Differences in dogs’ event related potentials in response to human and dog vocal stimuli: A non-invasive study

Anna Bálint, Huba Eleőd, Lilla Magyari, Anna Kis & Márta Gácsi
Recent advances in the field of canine neuro-cognition allow for the non-invasive research of brain mechanisms in family dogs. Considering the striking similarities between dog’s and human (infant)’s socio-cognition at the behavioural level, both similarities and differences in neural background can be of particular relevance. The current study investigates brain responses of N=17 family dogs to human and conspecific emotional vocalisations using a fully non-invasive ERP paradigm. We found that similarly to humans, dogs show...

Simulated trapping and trawling exert similar selection on fish morphology

Davide Thambithurai, Anita Rácz, Jan Lindström, Kevin Parsons & Shaun Killen
Commercial fishery harvest can influence the evolution of wild fish populations. Our knowledge of selection on morphology is however limited, with most previous studies focusing on body size, age and maturation. Within species, variation in morphology can influence locomotor ability, possibly making some individuals more vulnerable to capture by fishing gears. Additionally, selection on morphology has the potential to influence other foraging, behavioural, and life-history related traits. Here we carried out simulated fishing using two...

Multilocus molecular phylogenetic-led discovery and formal recognition of four novel root-colonizing Fusarium species from northern Kazakhstan and the phylogenetically divergent Fusarium steppicola lineage

Galiya K. Akhmetova, Dániel G. Knapp, Göksel Özer, Kerry O’Donnell, Imane Laraba, Aldabergen Kiyas, Vladimir Zabolotskich, Gábor M. Kovács & Orsolya Molnár
In this study, DNA sequence data were used to characterize 290 Fusarium strains isolated during a survey of root-colonizing endophytic fungi of agricultural and nonagricultural plants in northern Kazakhstan. The Fusarium collection was screened for species identity using partial translation elongation factor 1-α (TEF1) gene sequences. Altogether, 16 different Fusarium species were identified, including eight known and four novel species, as well as the discovery of the phylogenetically divergent F. steppicola lineage. Isolates of the...

Data from: Are brood sex ratios adaptive? The effect of experimentally altered brood sex ratio on nestling growth, mortality, and recruitment

Eszter Szász, Fanni Sarkadi, Eszter Szöllősi, Renáta Kopena, János Török & Balázs Rosivall
Brood sex ratios (BSRs) have often been found to be non-random in respect of parental and environmental quality, and many hypotheses suggest that non-random sex ratios can be adaptive. To specifically test the adaptive value of biased BSRs, it is crucial to disentangle the consequences of BSR and maternal effects. In multiparous species, this requires cross-fostering experiments where foster parents rear offspring originating from multiple broods, and where the interactive effect of original and manipulated...

Effects of chronic and acute predation risk on sexual ornamentation and mating preferences

Joachim G. Frommen, Timo Thuenken, Francesca Santostefano, Valentina Balzarini & Attila Hettyey
Phenotypic plasticity is wide-spread in animals, but how plastic responses to predation threat affect traits under sexual selection and influence mating preferences is not well understood. Here, we examined how chronic predation risk during development and acute predation risk during mate choice affect the expression of male secondary sexual traits and female mating preference in the three-spined stickleback, Gasterosteus aculeatus. Males reared under chronic predation risk developed less intense red breeding colouration but showed higher...

Functional integration of multiple sexual ornaments: signal coherence and sexual selection

Gergely Hegyi, Miklós Laczi, Márton Herényi, Gábor Markó, Gergely Nagy, Balázs Rosivall, Eszter Szász & János Török
The sexual ornamentation of animals typically consists of multiple distinct traits. The classical research approach focuses on differences among these traits, but this approach may often be misleading because of correlations among distinct sexual traits of similar origins. There are many published studies on the correlation structures of sexual traits, but the way receivers take into account the components of an integrated, multi-component trait system remains mostly unknown. Here we propose a general analytical framework...

Data from: An integrative skeletal and paleogenomic analysis of stature variation suggests relatively reduced health for early European farmers

Perry
Human culture, biology, and health were shaped dramatically by the onset of agriculture ~12,000 years before present (BP). This shift is hypothesized to have resulted in increased individual fitness and population growth as evidenced by archaeological and population genomic data alongside a decline in physiological health as inferred from skeletal remains. Here, we consider osteological and ancient DNA data from the same prehistoric individuals to study human stature variation as a proxy for health across...

Data for: Individual differences in song plasticity in response to social stimuli and singing position

Mónika Jablonszky, David Canal, Gergely Hegyi, Katalin Krenhardt, Miklós Laczi, Gábor Markó, Gergely Nagy, Balázs Rosivall, Eszter Szász, Sándor Zsebők & László Zsolt Garamszegi
Individual animals can react to the changes in their environment by exhibiting behaviours in an individual-specific way leading to individual differences in phenotypic plasticity. However, the effect of multiple environmental factors on multiple traits is rarely tested. Such a complex approach is necessary to assess the generality of plasticity and to understand how among-individual differences in the ability to adapt to changing environments evolve. This study examined whether individuals adjust different song traits to varying...
