Patterns of pollination interactions at community-level are related to the type and quantity of floral resources

Péter Török, Edy Fantinato, Judit Sonkoly, Péter Török & Gabriella Buffa
1. A fundamental question in community ecology is how the quantity of floral resources affects pollinator activity and how this relates to the structure and robustness of pollination networks. The issue has been mainly addressed at species level, while at community level several questions are still open. 2. Using a species-rich semi-natural grassland as model ecosystem, we explored the relationship between community-level quantity of floral resources, the number of flower visits at community-level and descriptors...

Avian plumage and eggshell colouration covary with sex-specific contributions to nest building

Jenő Nagy, Mark E. Hauber & Mark C. Mainwaring
Interspecific variation in sex-specific contributions to nest building remain poorly understood. We examine whether the colouration of parents and of eggs influences sex-specific nest building contributions in 521 species of Western Palearctic birds. Having colourful plumage and laying colourful eggs are costly because of the deposition of pigments (in feathers and eggs) and/or forming costly nanostructural substrates (of feathers). We tested the hypotheses that species in which females alone build nests (i) exhibit sexual plumage...

Social groups with diverse personalities mitigate physiological stress in a songbird

Csongor I. Vágási, Attila Fülöp, Gergely Osváth, Péter Pap, Janka Pénzes, Zoltán Benkő, Ádám Lendvai & Zoltán Barta
Social groups often consist of diverse phenotypes, including personality types, and this diversity is known to affect the functioning of the group as a whole. Social selection theory proposes that group composition (i.e. social environment) also influences the performance of individual group members. However, the effect of group behavioural composition on group members remains largely unexplored, and it is still contentious whether individuals benefit more in a social environment with homogeneous or diverse behavioural composition....

Are evolutionary transitions in sexual size dimorphism related to sex determination in reptiles? - Electronic supplementary material

Gergely Katona
Sex determination systems are highly variable in vertebrates, although neither the causes nor the implications of this diversity are fully understood. Theory suggests that sex determination is expected to relate to sexual size dimorphism, because environmental sex determination promotes sex-specific developmental bias in embryonic growth rates. Furthermore, selection for larger size in one sex or the other has been proposed to drive the evolution of different genetic sex determination systems. Here we investigate whether sex...

Data from: Sex-specific contributions to nest building in birds

Mark Mainwaring, Jenó Nagy & Mark Hauber
The causes and consequences of interspecific variation in sex-specific contributions to animal parental care are relatively well understood during pregnancy or incubation and during offspring provisioning, but comparative patterns of sex-biased investment during nest-, den-, or other shelter-building have been almost completely overlooked. This is surprising because birthing shelter properties have important fitness consequences for both parents and offspring. Here, we address this gap in our knowledge by testing predictions concerning sex-specific contributions to avian...

Post-restoration grassland management overrides the effects of restoration methods in propagule-rich landscapes

Csaba Tölgyesi, Csaba Vadász, Róbert Kun, András Csathó, Zoltán Bátori, Alida Hábenczyus, László Erdős & Péter Török
Grassland restoration is gaining momentum worldwide to tackle the loss of biodiversity and associated ecosystem services. Restoration methods and their effects on ecological community reassembly have been extensively studied across various grassland types, while the importance of post-restoration management has so far received less attention. Grassland management is an important surrogate for natural disturbances, which most ancient grasslands have co-evolved with. Thus, without the reintroduction of management-related disturbance, restoration targets are unlikely to be achieved...

Social organization in ungulates: revisiting Jarman's hypotheses

Karola Szemán, András Liker & Tamás Székely
Ungulates (antelopes, deer and relatives) have some of the most diverse social systems among mammals. To understand the evolution of ungulate social organisation, Jarman (1974) proposed an ecological scenario of how distribution of resources, habitat and feeding style may have influenced social organisation. Although Jarman’s scenario makes intuitive sense and remain a textbook example of social evolution, it has not been scrutinised using modern phylogenetic comparative methods. Here we use 230 ungulate species from 10...
