Homeostatic control of body fluid CO2 is essential in animals but poorly understood. C. elegans relies on diffusion for gas exchange and avoids environments with elevated CO2. We show that temperature, O2, salt-sensing neurons are also sensors mediating avoidance. AFD thermosensors respond to increasing by a fall then rise Ca2+ spike when decreases. BAG O2 ASE salt both activated remain tonically active while high persists. CO2-evoked responses require cGMP-gated ion channels. Atypical...
Brains organize behavior and physiology to optimize the response threats or opportunities. We dissect how 21% O2, an indicator of surface exposure, reprograms C. elegans' global state, inducing sustained locomotory arousal altering expression neuropeptides, metabolic enzymes, other non-neural genes. The URX O2-sensing neurons drive at O2 by tonically activating RMG interneurons. Stimulating is sufficient switch behavioral state. Ablating ASH, ADL, ASK sensory connected gap junctions does not...
Invasive alien plant species are usually disliked due to their high pressure on native communities. However, ecological effects pollinators complex: some provide abundant floral resources, boosting the number of pollinators, while they often disrupt plant-pollinator interactions by outcompeting plants. Our direct knowledge is mainly based single-species studies, understanding mechanism these complex needs multi-species field-based approaches. It also imperative clarify pros and cons invasive...
Pollinators are declining rapidly, largely due to land conversion and intensification of agriculture. To mitigate their crisis, low-disturbance habitats, such as sown wildflower plantings, could promote pollinators by restoration resources. However, comprehensive knowledge is lacking on how landscape context, spatial configuration age seasonality flower composition affect pollinator communities, especially from East-Central Europe. understand these effects, we established diverse native...
Mosquitoes, as vectors of various pathogens, have been a public health risk for centuries. Human activities such international travel and trade, along with climate change, facilitated the spread invasive mosquitoes novel pathogens across Europe, increasing mosquito-borne disease introduction their spread. Despite this threat, mosquito control in Hungary still relies predominantly on chemical treatments, which poses developing insecticide resistance local populations. While pyrethroid has...
<title>Abstract</title> Mosquitoes harbour diverse bacterial communities that are influenced by a number of factors, e.g., geography, host species, and developmental stage. Understanding these microbiotas is crucial for assessing their role as vectors in pathogen dissemination. Here, we compared the <italic>Aedes albopictus</italic> japonicus</italic> across eight countries: six Europe, plus USA Japan, from both adults larval stages when possible, using 16S rRNA amplicon sequencing. We found...
cGMP signaling is widespread in the nervous system. However, it has proved difficult to visualize and genetically probe endogenously evoked dynamics neurons vivo. Here, we combine Ca(2+) biosensors image dissect a network Caenorhabditis elegans oxygen-sensing neuron. We show that rise O2 can evoke tonic increase requires an atypical O2-binding soluble guanylate cyclase sustained until oxygen levels fall. Increased leads response neuron depends on cGMP-gated ion channels. Elevated of...
Aerobic animals constantly monitor and adapt to changes in O 2 levels. The molecular mechanisms involved sensing are, however, incompletely understood. Previous studies showed that a hexacoordinated globin called GLB-5 tunes the dynamic range of -sensing neurons natural C. elegans isolates, but is defective N2 lab reference strain (McGrath et al., 2009; Persson 2009). enables sharp behavioral switch when between 21 17%. Here, we show also confers rapid cellular recovery from exposure...
Uranotaenia unguiculata Edwards, 1913 is a species of mosquito (Diptera: Culicidae) native to central Europe. Recently novel lineage the West Nile virus (WNV-lineage 4c) was identified in pools adult female Ur. unguiculata. To increase body knowledge about this species, various trapping methods were evaluated determine most efficient method for capturing unguiculata.Sound traps collected equivalent numbers as low-hanging light-baited downdraft traps. Hosts Pelophylax lessonae and P....
Background The mosquito Aedes koreicus (Edwards, 1917) is a recent invader on the European continent that was introduced to several new places since its first detection in 2008. Compared other exotic mosquitoes with public health significance invaded Europe during last decades, this species’ biology, behavior, and dispersal patterns were poorly investigated date. Methodology/Principal findings To understand population relationships within Europe, fragment of cytochrome oxidase I (COI or...
Human and animal vector-borne diseases, particularly mosquito-borne are emerging or re-emerging worldwide. Six Aedes invasive mosquito (AIM) species were introduced to Europe since the 1970s: aegypti, Ae. albopictus, japonicus, koreicus, atropalpus triseriatus. Here, we report results of AIMSurv2020, first pan-European surveillance effort for AIMs. Implemented by 42 volunteer teams from 24 countries. And presented in form a dataset named "AIMSurv Invasive Mosquito harmonized Europe. AIM-COST...
West Nile virus (WNV) is a widely distributed mosquito-borne flavivirus. WNV strains are classified into several genetic lineages on the basis of phylogenetic differences. Whereas lineage 1 viruses worldwide, 2 was first detected outside Africa in Hungary 2004. Since then, WNV-associated disease and mortality animal human hosts have been documented periodically Hungary. After detection from pool Culex pipiens mosquitoes 2010, samples were collated sources tested 2-year monitoring program....
Urbanization can be a significant contributor to the spread of invasive mosquito vector species, and diseases they carry, as urbanized habitats provide access great density food resources (humans domestic animals) offer abundant breeding sites for these vectors. Although anthropogenic landscapes are often associated with presence we still have little understanding about relationships between some built environment. This study explores association urbanization level occurrence Aedes...
Abstract Expertise in biodiversity research (taxonomy, faunistics, conservation with taxonomic background) appears to decline worldwide. While the “taxonomic impediment” is discussed extensively literature, much fewer papers focus on identification crisis, i.e., decreasing number of experts who can identify species, and species-based research. As a test case explore gravity we chose Hungary, Central European country strong history comprehensive expertise output. We set out answer two main...
Abstract Plant invasions can lead to homogeneous communities with decreased functional diversity. However, invasive plants, various morphological and phenological traits, may drive pollinator in a less predictable, more complex way. They promote pollinators compatible their floral while leaving others without foraging resources. Our observational study on 10 herbaceous species applied trait‐based approach investigate plant invasion‐driven changes resources, hoverfly bee communities. We...
Abstract Climate change, intensified tourism and trade activity have resulted in several exotic mosquito species invading the temperate zone, with considerable ecological economic consequences, as well threats to human health, due pathogen‐transmitting role of these organisms. Accordingly, three invasive ( Aedes albopictus , Ae. japonicus koreicus ) been described last decade Hungary, a Central European country. It is crucial understand how are introduced their distribution expanded at...
Avian host species have different roles in the amplification and maintenance of West Nile virus (WNV), therefore identifying key taxa is vital understanding WNV epidemics. Here, we present a comprehensive case study conducted on red-footed falcons, where host-vector, vector-virus host-virus interactions were simultaneously studied to evaluate contribution circulation qualitatively. Mosquitoes trapped inside falcon nest-boxes by method originally developed for capture blackflies midges. We...
Wild bees, hoverflies and wasps are valuable ecosystem service providers in agricultural systems through pollination biological control, their species richness, abundance reproductive success well indicate health. However, they often limited by foraging nesting resources that major drivers behind steep decline. Although agri-environmental measurements improve for these groups, wider landscape-scale impacts basically unknown. Here, we questioned whether 2–3 years old, sown set-aside fields...
Abstract Invasive plants modify native plant communities with serious consequences on plant-pollinator interactions. Invasion by common milkweed ( Asclepias syriaca L.) threatens natural and agricultural habitats in Europe, unknown effects pollinators. Its special flower structure, habitat requirements phenology offer novel insights into pollination ecology aspects of invasion. We compared flowering pollinator between invaded control sites, the visitors milkweed. Wild bees hoverflies did not...
ABSTRACT Biodiversity declines in an unprecedented way, mostly due to land use change. Restoration interventions proved be one of the most effective tools halt decline, especially ecosystems such as agricultural fields. Evidence-based, locally adapted recommendations on grassland restoration, however, are often missing, so we present a novel approach for that can implemented anywhere and based scientific rigor. In recently started long-term field ecological study, established 0.5 ha...
The Red-footed Falcon (Falco vespertinus) is a strictly protected raptor species in Hungary (ca 600 pairs).It naturally breeds rook, crow or magpie nests that are rebuilt every year, however, most of these disappeared by the end 20th century.In early 2000's more than 3,000 artificial nest boxes were installed country, increasing number breeding pairs considerably.This prompts question whether birds might face an increased nest-dwelling ectoparasites due to annual re-use nesting sites.The...
Abstract Due to their potential role in pathogen transmission, invasive mosquitoes pose considerable threats human and animal health. Several studies have identified the most important ecological drivers mediating establishment spread of key mosquito species (e.g., Aedes aegypti , Ae. albopictus ), made predictions for future distribution. We evaluated effect an exhaustive list environmental predictors on distribution three Hungary ( japonicus, koreicus) by using same standards data...
Nature conservation–related citizen science (NCCS) has grown rapidly worldwide in previous years. In Hungary, a few (CS) projects have been operating for years and some only recently launched. Our aim herein is to assess the performance of eight Hungarian NCCS three dimensions: a) science, b) nature conservation, c) participants’ development. An evaluation framework was developed assessment. results show that Common Bird Monitoring Program performed best overall. This also oldest project...
ABSTRACT Semi‐natural grasslands and their biodiversity decline rapidly, although they are key elements of agricultural landscapes. Therefore, there is a need for the re‐establishment semi‐natural in intensively managed farmlands (e.g., via sowing wildflower seeds). Our knowledge, however, limited on how different arthropod groups may respond to such newly established fields. This knowledge gap especially relevant Pannonian biogeographical region, more generally Central Europe, where little...
