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...

Full-text available
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...
Article
Full-text available
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...

Plant species performance in rangelands highly depends on the effect of grazing and also on the occurrence of unpalatable benefactor species that can act as biotic refuges protecting neighboring plants from herbivores. The balance between facilitation and competition may changes with the benefactor density. Despite the high number of studies on the...
Article
Full-text available
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...
Article
Full-text available
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...

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...

The increase in road networks facilitates the dispersal of many species of plants along roadsides. In these special habitats, the use of deicing salt can provide suitable habitat conditions for the establishment of stress-tolerant halophytes. This study investigates the spread of an alien halophyte Cochlearia danica in continental Europe. This spec...

Long-term seed viability is of crucial importance for short-lived species, since persistent seed banks can buffer the fluctuations in the establishment of plants from year to year. Temporarily flooded habitats are an unpredictable environment for plants, and for some species the only chance they have of surviving is the formation of persistent seed...

Régóta ismert tény, hogy a madarak szerepet játszanak számos növényfaj terjesztésében. Charles Darwin A fajok eredete című könyvében leírta azt is, hogy ez a folyamat alapvetően kétféle módon valósulhat meg: a kültakaróra (lábra, tollazatra) tapadt vagy az állat által elfogyasztott, de a tápcsatornájából épségben (megemésztetlenül) előkerülő terjes...

Orchidaceae are a diverse and widespread family of flowering plants. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 25,000 currently accepted species, distributed in ca. 750 genera. Many species of this charismatic group are of key conservation importance. European terrestrial orchids are ideal for studying the effects of pollination mode on flowering phenology, because, although they are mainly self-compatible, they maintain diverse pollination modes: many of them are self-pollinating (including obligate and facultative inbreeders), others reward pollinators with nectar and approximately one-third of the species use various forms of floral deception.
Project
On the one hand, parallel with the decline of interest in taxonomic and systematic studies, some scientists and decision makers have questioned over the last 25 years the importance of biological collections, considering mostly budget limitations. On the other hand, dried and pressed plant specimens stored in biological collections are being used as never before in wide range of scientific researches. Herbaria contain long-term data for a wide range of taxa and provide unique opportunities to evaluate for example the importance of life-history components in driving species-specific responses to climate change. Our aim is to create databases of Hungarian vascular plant collections, including the main attributes of each herbarium specimen, accompanied by digital photos, which may be useful for floristic research or even “new type herbarium utilization” in the near future.
