Urbanization creates novel environments for wild animals where selection pressures may differ drastically from those in natural habitats. Adaptation to urban life involves changes various traits, including behavior. Behavioral traits often vary consistently among individuals, and these so-called personality can be correlated with each other, forming behavioral syndromes. Despite their adaptive significance potential act as constraints, little is known about the role of animal syndromes...
The Avars settled the Carpathian Basin in 567/68 CE, establishing an empire lasting over 200 years. Who they were and where came from is highly debated. Contemporaries have disagreed about whether were, as claimed, direct successors of Mongolian Steppe Rouran that was destroyed by Turks ∼550 CE. Here, we analyze new genome-wide data 66 pre-Avar Avar-period individuals, including 8 richest burials further elite sites Avar's core region. Our results provide support for a rapid long-distance...
Predators influence the behaviour of prey and by doing so they potentially reduce pathogen transmission a vector. Arthropod predators have been shown to consumption plant biomass pest herbivores, but their cascading non-consumptive effect on vector insects' feeding subsequent has not investigated experimentally before. Here we examined predator-mediated mechanisms using Wheat Dwarf Virus that is transmitted leafhopper, Psammotettix alienus. We applied in situ hybridization localize which...
Abstract Social foraging is thought to provide the possibility of information transmission between individuals, but this advantage has been proved only in a handful species and contexts. We investigated how social connections captive flocks house sparrows ( Passer domesticus ) affected discovery (i.e. feeding for first time from) two hidden food patches presence informed flock-mates. At first-discovered most-exploited patch birds order presumably contributed greater exploitation patch....
Social network theory provides a perfect tool to better understand the population-level consequences of how individuals interact and make their decisions; however, this approach is generally overlooked among evolutionary biologists interested in social relationships. Here, we used analysis examine patterns leader-follower interactions relation individual characteristics foraging groups free-living rock sparrows (Petronia petronia). We found that yellow feather ornamentation, carotenoid-based...
Phenotypic plasticity is extremely widespread in the behaviour, morphology and life‐history of animals. However, inducible changes production defensive chemicals are described mostly plants surprisingly little known about similar chemical defences Inducible may be common animals because many to produce toxins, synthesis toxins likely costly, there a few cases adjusting their toxin environmental conditions. We outline what occurrence argue that immense potential for progress this field....
Non-consumptive effects (NCEs) of predators are part the complex interactions among insect natural enemies and prey. NCEs have been shown to significantly affect prey foraging feeding. Leafhopper's (Auchenorrhyncha) lengthy phloem feeding bouts may play a role in pathogen transmission vector species also exposes them predation risk. However, on leafhoppers scarcely studied, we lack basic information about how anti-predator behaviour influences these species. Here report study non-consumptive...
Genetically highly divergent picornavirus (Newt/2013/HUN, KP770140) was detected using viral metagenomics in faecal samples of free-living smooth newts (Lissotriton vulgaris). Newt identified by reverse transcription-polymerase chain reaction (RT-PCR) six (25 %) the 24 originating from individuals caught two out investigated natural ponds Hungary. The first amphibians expands host range members Picornaviridae, and opens a new research field evolution lower vertebrates. represents novel...
Abstract Due to recent changes in regulation, acetamiprid has become the only neonicotinoid that can be applied without restrictions and open field cultivations EU from 2021. We provide an overview of current knowledge on effects this insecticide bumblebees assessed whether available empirical evidence supports claim poses negligible risk these pollinators. found there is limited data lethal sublethal pesticide bumblebees. While assessment results suggest field-realistic concentrations have...
Social behaviour of group-living animals is often influenced by the relatedness individuals, thus understanding genetic structure groups important for interpretation costs and benefits social interactions. In this study, we investigated in feeding aggregations free-living house sparrows (Passer domesticus) during nonbreeding season. This species a frequent model system studies (e.g. aggression, foraging), but lack adequate information on kin sparrow flocks. During two winters, ringed...
Abstract About one‐third of human papillomavirus (HPV) types infect the anogenital tract. High‐risk genital HPV (such as 16, 18, 31, 33, and 35) are linked causally to development cervical cancer. The long control region (LCR) genome regulates replication transcription viral genome. In this study, functional significance nucleotide sequence variation within LCR 31 was investigated. amplified by polymerase chain reaction (PCR) from 41 positive samples Hungarian women.

1. Inducible defences are ubiquitous in the animal kingdom, but little is known about facultative changes chemical response to predators, especially so vertebrates. 2. We tested for predator-induced toxin production of larval common toads (Bufo bufo), which synthesize bufadienolide compounds. 3. The experiment included larvae originating from three permanent and temporary ponds reared presence or absence cues predators: dragonfly larvae, newts fish. 4. Tadpoles raised with predation risk...
Recent findings indicate that the utilization of social information, produced inadvertently by other individuals through their spatial location and/or interaction with environment, may be ubiquitous in animal kingdom. If so, information-mediated effects on population growth and interspecies interactions more prevalent than previously thought. However, little is known about how information spread among non-grouping individuals, i.e., animals do not form cohesive groups therefore attraction...
Abstract Although pesticide-free techniques have been developed in agriculture, pesticides are still routinely used against weeds, pests, and pathogens worldwide. These agrochemicals pollute the environment can negatively impact human health, biodiversity ecosystem services. Acetamiprid, an approved neonicotinoid pesticide EU, may exert sub-lethal effects on pollinators other organisms. However, our knowledge scope severity of such is incomplete. Our experiments focused insecticide...
Abstract Semenogelin I and II (Sgs) are the major component of human semen coagulum. The protein is rapidly cleaved after ejaculation by a prostate‐specific antigen, resulting in liquefaction coagulum progressive release motile spermatozoa. Sgs inhibit sperm motility; however, there currently no information on its effect membrane. This study investigated role motility through regulation membrane potential permeability. Fresh samples were obtained from normozoospermic volunteers, studies...
