Flower Visitation through the Lens: Exploring the Foraging Behaviour of Bombus ...
Varga-Szilay, Zsófia; Szövényi, Gergely; Pozsgai, GaborTo understand the processes behind pollinator declines and for the conservation of pollination services, we need to understand fundamental drivers influencing pollinator behaviour. Here, we aimed to elucidate how wild bumblebees interact with three plant species and investigated their foraging behaviour with varying flower densities. We video-recorded Bombus terrestris in 60 × 60 cm quadrats of Lotus creticus, ...
Bridging biodiversity and gardening: Unravelling the interplay of socio-demogra...
Varga-Szilay, Zsófia; Fetykó, Kinga Gabriela; Szövényi, Gergely; Pozsgai, GaborThe expansion of urban areas threatens biodiversity and disrupts ecological relationships, thereby impeding key ecosystem services. To avert irreversible consequences, there is a focus on improving the biodiversity value of domestic gardens. We employ machine learning and network analysis and examine gardening practices and garden owners’ environmental consciousness in Hungary through a questionnaire-based stud...
Biodiversity loss impacts top-down regulation of insect herbivores across ecosy...
Wyckhuys, Kris A.G.; Pozsgai, Gabor; Ben Othman, Ibtissem; Sanchez-Garcia, Francisco J.; Elkahky, MagedBiodiversity loss, as driven by anthropogenic global change, imperils biosphere intactness and integrity. Ecosystem services such as top-down regulation (or biological control; BC) are susceptible to loss of extinction-prone taxa at upper trophic levels and secondary ‘support’ species e.g., herbivores. Here, drawing upon curated open-access interaction data, we structurally analyze trophic networks centered on ...
Improving biodiversity in Central and Eastern European domestic gardens needs r...
Varga-Szilay, Zsófia; Barševskis, Arvids; Benedek, Klára; Bevk, Danilo; Jojczyk, Agata; Kristin, Anton; Růžičková, Jana; Seric Jelaska, LucijaAmid ongoing urbanisation and increasing anthropogenic activities, domestic gardens, while cannot replace natural habitats, play a crucial role in enhancing urban biodiversity by supporting green areas and as parts of ecological corridors. Moreover, these biodiversity-friendly gardens also improve human well-being and foster a connection between nature and people. We circulated an online questionnaire between 2...
The BALA project: A pioneering monitoring of Azorean forest invertebrates over ...
Pozsgai, Gabor; Lhoumeau, Sébastien; Rosário, Isabel Amorim Do; Boieiro, Mário; Cardoso, Pedro; Costa, Ricardo; Ferreira, Maria Teresa; Leite, AbrãoGlobally, there is a concerning decline in many insect populations, and this trend likely extends to all arthropods, potentially impacting unique island biota. Native non-endemic and endemic species on islands are under threat due to habitat destruction, with the introduction of exotic, and potentially invasive, species, further contributing to this decline. While long-term studies of plants and vertebrate faun...
New findings of terrestrial arthropods from the Azorean Islands
Boieiro, Mário; Varga-Szilay, Zsófia; Costa, Ricardo; Crespo, Luis; Leite, Abrão; Oliveira, Raúl; Pozsgai, Gabor; Rego, Carla; Calado, HugoThe knowledge on taxonomic diversity of arthropods is key to better understanding the biodiversity patterns and processes and guiding sustainable conservation strategies and practices. In the Azores, terrestrial arthropods are relatively well-inventoried following the publication of comprehensive checklists that have been regularly updated. Nevertheless, every year, new species are found as a result of new arri...
Functional structure of the natural enemy community of the fall armyworm, Spodo...
Wyckhuys, Kris A.G.; Akutse, Komivi S.; Amalin, Divina M.; Araj, Salah-Eddin; Barrera, Gloria; Joy B. Beltran, Marie; Ben Fekih, IbtissemEcosystem functions such as biological pest control are mediated by the richness and abundance of service providers i.e., biological control agents (BCAs), relative contributions of individual taxa and community structure. This is especially relevant in the native range of agricultural herbivores, where a speciose community of co-evolved BCAs can prevent them from attaining pest status. Here, we use a powerful ...
Arthropod traits as proxies for abundance trends in the Azorean Islands
Oyarzabal, Guilherme; Cardoso, Pedro; Rigal, François; Boieiro, Mário; Santos, Ana M. C.; Amorim do Rosário, Isabel; Malumbres-Olarte, JagobaHuman activities drive ecological transformation, impacting island ecosystems from species diversity to ecological traits, mainly through habitat degradation and invasive species. Using two unique long-term datasets we aim to evaluate whether species traits (body size, trophic level, dispersal capacity and habitat occupancy) can predict temporal variations in the abundance of endemic, indigenous (endemic and na...
Flower visitation through the lens: Exploring the foraging behaviour of Bombus ...
Varga-Szilay, Zsófia; Szövényi, Gergely; Pozsgai, GaborTo understand the processes behind pollinator declines, and thus to maintain pollination efficiency, we also have to understand fundamental drivers influencing pollinator behaviour. In this study, we aim to explore the foraging behaviour of wild bumblebees, recognizing its importance from economic and conservation perspectives. We recorded Bombus terrestris on Lotus creticus, Persicaria capitata, and Trifolium ...
