Középiskolás koromban határoztam el, hogy a hazai növényvilág ritka és szépséges fajait szeretném fényképezni és vizsgálni. Érdeklődésemet legelőször a kosborfélék keltették fel, és ez a „szerelem” a mai napig megmaradt. Ugyanakkor a kezdetektől kiemelt figyelmet szenteltem a veszélyeztetett fajoknak, amelyek kutatását hivatásomul választottam. Enn...

Although long-distance dispersal (LDD) events are rare and stochastic, they are disproportionately important and drive several large-scale ecological processes; yet, we have a very limited understanding of their frequency, extent and consequences. Humanity intentionally spreads several species, which is associated with the accidental dispersal of o...

Road management practices, such as winter de-icing create ideal habitats and competitive advantage for salt-tolerant species. We aimed to map the occurrences of halophytes along roads in Hungary. Furthermore, we tested factors that might play a role in the roadside occurrences of five chosen native halophytes from rare to common, we encountered dur...

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...

Although long-distance dispersal (LDD) events are considered to be rare and highly stochastic, they are disproportionately important and drive several large-scale ecological processes. The realisation of the disproportionate importance of LDD has led to an upsurge in studies of this phenomenon; yet, we still have a very limited understanding of its...

One of the main goals of the EU Biodiversity Strategy for 2030 is to avoid further loss of biodiversity and to restore ecosystems. These efforts can be facilitated by compiling the main research topics related to conservation biology to provide new evidence for the most urgent knowledge gaps, and publicise it to researchers, research funders and po...

A temetkezési helyekre az elmúlás és az emlékezés helyszíneként tekintünk, amelyek tájképi, történeti és kulturális értéket is képviselnek. Arról azonban sokáig kevés átfogó ismeretünk volt, hogy természeti értékek sokaságának is otthont adnak. Cikkünk szerzőjének vezetésével ezen változtatott az a 2013-ban indult hosszú távú kutatási program, amel...

This paper reports the occurrence of a North American salt-tolerant taxon, Diplachne fusca subsp. fascicularis (Lam.) P.M.Peterson et N.Snow in Hungary (Central-Europe). Two earlier Hungarian observations of D. fusca were known from 1915, near Győr (West Transdanubia), later the taxon was collected by Pénzes in 1958, in downtown Budatétény (central...

The spread of alien species with the expansion of road networks and increasing traffic is a well-known phenomenon globally. Besides their corridor effects, road maintenance practices, such as the use of de-icing salts during winter facilitate the spread of halophyte (salt tolerant) species along roads. A good example is Plantago coronopus, a mainly...

Seminatural habitats are declining throughout the world; thus, the role of small an-thropogenic habitats in the preservation of plants is becoming increasingly appreciated. Here, we surveyed the orchid flora of roadside verges in five Central European countries (Austria, Hungary, Romania, Slovakia, and Slovenia) and tested how the surrounding lands...

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...

Fen pondweed (Potamogeton coloratus) is a characteristic species of oligotrophicwaters, therefore, one of the rarest and most endangered aquatic plants in Europe because of habitat loss and population decline all over the continent. In Hungary, all of its populations disappeared during the 1950s and 1960s and then dramatically recovered in recent y...

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....

Field studies have shown that waterbirds, especially members of the Anatidae family, are major vectors of dispersal by endozoochory for a broad range of plants lacking a fleshy fruit, yet whose propagules can survive gut passage. Widely adopted dispersal syndromes ignore this dispersal mechanism, and we currently have little understanding of what t...

Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research sp...

The widely accepted “endozoochory syndrome” is assigned to angiosperm diaspores with a fleshy, attractive tissue and implies the existence of adaptations for protection against digestion during gut passage. This syndrome has led diaspore fleshiness to be emphasized as the exclusive indicator of endozoochory in much of the ecology and biogeography r...

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).

Ant-plant interactions such as myrmecochory, i.e. mutualistic, ant mediated seed dispersal, are interesting in evolutionary biology, ecology and conservation. Many plant species are known to have developed nutrient-rich attachments to seeds (elaiosomes) in order to attract ants. This interaction is obligatory and essential for the plant, hence a be...

The increase in road networks facilitates the dispersal of many species of plants along roadsides.

1. Modern literature on plant dispersal by birds focuses mainly on the importance of frugivory and scatter-hoarding, yet recent studies show that endozoochory by migratory waterbirds is an important mechanism of long-distance dispersal for a broad range of plants. Nevertheless, there is a lack of empirical field studies that identify the plants dis...

We aimed to introduce and test the "seed mass-distribution range trade-off" hypothesis , that is, that range size is negatively related to seed mass due to the generally better dispersal ability of smaller seeds.
