The value of recreational anglers' ecological knowledge and perceptions have come to prominence in the past few decades. Based on recent studies, their observations might include those of alien organisms and, therefore, might be particularly important in monitoring and revealing the causes of aquatic invasions. Although the number of registered ang...
Nagy, A., Neményi, Zs., Hagyó, A. et al. The knowledge and perceptions of recreational anglers related to alien plant species in freshwater ecosystems: a case study from Hungary. Aquatic Conservation: Marine and Freshwater Ecosystems (2025), https://doi.org/10.1002/aqc.70082 // Supplementary figure // Data
Az elhagyott, elveszített vagy eldobott halász- és horgászeszközök egyaránt szennyezik a tengeri, a partmenti, és az édesvízi ökoszisztémákat, jelentős negatív hatásokat keltve társadalmi, gazdasági és környezetvédelmi vonatkozásokban is. Ezek az eszközök legtöbbször különféle halászhálók, de idesorolható minden olyan felszerelés (kötelek és zsinór...
Az eszköz nélküli halászathoz és rákászathoz köthető hagyományos ökológiai tudás egyes szegmensei élelemszerző, de rekreációs céllal is a világ számos táján napjainkig fennma-radtak. A jelenséget a néprajzi irodalomnak köszönhetően a Kárpát-medencében is közel két év-századon keresztül viszonylagos alapossággal dokumentálták. Mivel a tevékenységet...
The dispersal of fish into distant and isolated habitats remains a topic of continuous discussion in the field of fish biogeography. This is particularly relevant due to the perceived limitation of fish movement to what is known as active dispersal. Fish migration is often confined to interconnected water bodies, underscoring the significance of di...
Nagy, J., Hauber, M. E., Löki, V. & Mainwaring, M. C. (2024) Plumage and eggshell colouration covary with the level of sex-specific parental contributions to nest building in birds. The Science of Nature, 111(2): 12. // Data available at Figshare https://doi.org/10.6084/m9.figshare.25268398.v1
Interspecific variation in sex-specific contributions to prenatal parental care, including avian nest building, is becoming increasingly better understood as we amass more information on more species. We examined whether sex-specific nest building contributions covary with the colouration of parents and their eggs in 521 species of Western Palearct...
Abandoned, lost, or discarded fishing gears (ALDFG) are major pollutants in water ecosystems, however, there is a serious lack of estimates on the loss of recreational fishing gears worldwide. To fill this gap, some recreationists like magnet fishers, who use neodymium magnets to retrieve metal items from water, can provide additional information....
Neményi, Z., Nagy, A., Hagyó, A. et al. Tracking abandoned, lost or discarded fishing gears of anglers by analyzing magnet fishers’ catch. Hydrobiologia (2024). https://doi.org/10.1007/s10750-023-05453-7 // Supplementary figure
Despite broad interest and recent experimentation, there is no single ecological model accounting for the adaptive significance of the diversity of avian eggshell colouration. The often blue-green eggs of Turdus thrushes are a charismatic example of this, having long captured cultural and scientific attention. Although the biology and evolutionary...
The existing plant trait databases’ applicability is limited for studies dealing with the flora and vegetation of the eastern and central part of Europe and for large-scale comparisons across regions, mostly because their geographical data coverage is limited and they incorporate records from several different sources, often from regions with marke...
Facing global climate change is a great challenge for species. Numerous species respond to a changing climate by shifting their geographical ranges, adapting to the local climate or finding microrefugia to persist under unfavorable macroclimatic conditions. Orchids are frequently found in roadside verges, and it was demonstrated that roadsides coul...
Fekete, R., Vincze, O., Nagy, J., Löki, V., Süveges, K., Bódis, J., Malkócs, T., Lovas-Kiss, Á. & Molnár, V. A. (2023) North-facing roadside slopes: anthropogenic climate microrefugia for orchids. Global Ecology and Conservation, 47: e02642. // Content: Raw data // Species information // Detailed results of models
1. The expansion of alien plant species is of global concern, yet our understanding of their dispersal mechanisms is limited. Here we address the potential of alien plant seeds to disperse via ingestion, transport and egestion in waterfowl (endozoo-chory). Based on their general rapid expansions, we expected alien plant species to have several adva...
The loss of plant functional diversity associated with biological invasion is a main subject of invasion biology, but still understudied in case of aquatic plants. We calculated functional richness, evenness, divergence and community-weighted mean trait values of aquatic plant communities for 20 plots, half invaded and half non-invaded by alien spe...
Olive and olive oil production is one of the main agricultural activities in the Mediterranean region. Besides their economic importance, traditional and organic olive groves were also hypothesized to contribute to biodiversity conservation. For instance, the presence of terrestrial orchids in olive groves has long been known. It is, however, not w...
We present PADAPT 1.0, the Pannonian Database of Plant Traits which relies on regional data sources and integrates existing data and new measurements on a wide range of traits and attributes of the plant species of the Pannonian Biogeographical Region and makes it freely accessible at www.padapt.eu. The current version covers the species of the reg...
Poplar monocultures are some of the most common short-rotation coppices. While they are most often considered of low environmental value, they have recently gained recognition for their multifaceted role in ecological engineering, such as carbon sinks, soil remediators or green energy producers. Nonetheless, the biodiversity of poplar plantations r...

A hagyományos és helyi ökológiai tudás – a nemzetközi szakirodalomban traditional ecological knowledge és local ecological knowledge – alaposabb megismerése a XXI. század leggyorsabban fejlődő tudományágai közé tartozik. A hagyományos tudásanyag elsősorban a tájjal legszorosabb kapcsolatban élő gazdálkodók, pásztorok, halászok természet megfigyelés...
Trait-based ecology is gaining ground nowadays on species-based ecology: the number of research and publication focusing on the ecological role of taxa instead of the species themselves increased significantly in the last two decades. One great advantage of this approach is that communities with different species composition due to great geographic...
The expansion of alien plant species is of global concern, yet our understanding of their dispersal mechanisms is limited, especially regarding the role of migratory birds. We hypothesize that invasiveness of alien wetland plants might depend on specific adaptations that ensure high seed survival in the digestive tract of waterfowl, ensuring their...
Törökország orchideaflórájára jellemző, hogy egyrészt az egyik leggazdagabb a Mediterrán térségben, másrészt a mezőgazdaság intenzívebbé válása, a tájhasználat megváltozása, az élőhelyek átalakulása, a túllegeltetés és a gumók kiásásával járó szálep-gyűjtés miatt rendkívül veszélyeztetett. Közleményünkben szeretnénk felhívni a figyelmet a gazdasági...
In order to explore their orchid flora, we performed surveys of 96 Azerbaijani burial places in 2018 and 2019. Altogether, 28 orchid taxa were found in 37 visited cemeteries. In the orchid diversity a remarkable pattern was observed: geographic latitude was significantly and positively related to the number of taxa and number of individuals. The mo...

The role of anthropogenically influenced habitats in conserving elements of the original wildlife has increased worldwide simultaneously with the disappearance of natural sites. Burial places are able to conserve original elements of the wildlife, and this fact has been known for at least a century. To this day, little is known about long‐time chan...
Fish have somehow colonized isolated water bodies all over the world without human assistance. It has long been speculated that these colonization events are assisted by waterbirds, transporting fish eggs attached to their feet and feathers, yet empirical support for this is lacking. Recently, it was suggested that endozoochory (i.e., internal tran...
For 491 vascular plant species we provide original data of five leaf traits: fresh mass, dry mass, leaf area (LA), specific leaf area (SLA) and leaf dry matter content (LDMC). We are focusing on species that are rare and/or endemic to the Pannonian Ecoregion. We provide data on more than 200 species, which are not yet included in the TRY database....
Epipactis tallosii is considered as one of the highly threatened European orchid species due to its local distribution and small isolated populations that are characterized by decreasing trends. The species is now enlisted in the endangered (EN) category of the Red List. Nevertheless, during the last decade, multiple new populations of the species...

Azerbajdzsánról ma kapásból a gazdag szénhidrogénkészletek és néhány politikai manőver juthat az eszünkbe. Ugyanakkor az ország - éppen a gazdag kőolaj-és földgázkészleteinek köszönhetően - a nyugati típusú fejlődés útjára lépett, ám a vidéki Azerbajdzsán máig fenntartható, zömében önnfenntartó módon gazdálkodik természeti kincseivel. Bár Baku felh...
Several important habitats have become threatened in the last few centuries in the Mediterranean Basin due to major changes adopted in land‐use practices. The consequent loss of natural and seminatural orchid habitats leads to the appreciation of small anthropogenic habitats, such as cemeteries and roadside verges. Colonization of cemeteries and ro...
During the past centuries human-induced land use changes resulted in a considerable loss of natural habitats worldwide. In transformed landscapes historical burial places such as cemeteries and churchyards can have the potential for biodiversity conservation. In our review we aimed at evaluating the conservation role of these sites and at revealing...
In the face of worldwide habitat loss, the role of human-shaped habitats in conserving biodiversity is becoming increasingly important. Due to their special cultural role, cemeteries can preserve parts of the native vegetation when the surrounding landscape becomes degraded. However, these special refuges are threatened by human encroachment and ch...
Front and back cover of the book entitled "Life after death. Wildlife of cemeteries".
Cemeteries are mostly perceived as undisturbed places where we can remember the deceased loved ones. From another perspective, they also represent historical and cultural values throughout the world. It has only recently been demonstrated that cemeteries are home to signifcant natural values, of which we have very little knowledge in general, and t...
Maps connecting to the book entitled "Life after death. Wildlife of cemeteries".
Despite huge habitat losses caused by agricultural intensification, dry grasslands still represent one of the most diverse ecosystems in Europe. Their highly fragmented remnants are often preserved in man-made or human-influenced habitats (e.g., kurgans, roadside verges or cemeteries). In recent decades the significance of cemeteries as suitable ha...
Disappearing botanical and cultural heritage of wooden headboard-graveyards in Eastern-Hungary and Transylvania (Romania)
Degradation or disappearance of natural habitats are global phenomena nowadays, hence the role of small and secondary (seminatural) habitats like cemeteries in preserving natural values are more and more appreciated. The botani...
Harvest of orchid tubers for salep production is widespread in southwestern Asia and the Balkans and constitutes a major conservation risk for wild orchid populations. Synanthropic habitats, such as graveyards, are important refuges for orchids and other organisms and could offer protection from salep harvesting because of their special cultural ro...
Alterations in traditional land use practices have led to severe declines in the area of semi-natural grasslands, thereby seriously threatening plant and animal species dependent on these habitats. Small anthropogenic managed habitats, like roadsides can act as refuges and might play an important role in conserving these species. Colonization of ro...

p> Sustainable (and adaptive) management of natural resources is usually based on long term local experiences with nature. Local traditional communities often possess rich ecological knowledge connected to nature and traditional resource use and management. This knowledge can provide unexpected new information for researchers, and show new opportun...
Elatine gussonei (Sommier) Brullo et al. is a rare freshwater plant previously assumed to be endemic to Lampedusa and the Maltase archipelago. Taxonomic uncertainties within the Elatine genus may have caused E. gussonei populations to be overlooked in the Mediterranean region. To clarify the distribution of E. gussonei, we reviewed Elatine specimen...
Spiraea crenata was categorised as a species extinct from Hungary at the end of the 20 th century. This steppe-relic species was rediscovered in 2000 in a rural graveyard (Pusztamonostor). As a result of our recent survey of 294 Pannonian graveyards, we found further 12 localities of S. crenata. We also found 27 populations of further protected pla...
Graveyards are unique habitats and well-known as refugia for many organisms, as traditional habitat management of graveyards lends them serious conservational value. However, the impact of religious affiliation to the natural values of graveyards has not been evaluated yet, although religion can have an impact on them through different habits and m...
