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...

Interactions among native and invasive species may affect management outcomes and goals. We implemented different mowing regimes to control the invasive Solidago gigantea and restore natural diversity, and also examined interactions between Solidago and a European native competitor, Tanacetum vulgare in the context of these regimes. Experimentally...

This paper examines Badenian (middle Miocene) macroinvertebrates – corals and molluscs – from the Pécs-Danitzpuszta sand pit (Mecsek Mts, SW Hungary) in order to extend our knowledge on Miocene normal marine deposits of the Mecsek region. Corals occur reworked in the upper Miocene sand that was deposited in the brackish Lake Pannon, and presumably...

Developing invasive plant management strategies is an important task in modern ecology, conservation biology and land management. Solidago gigantea is considered a problematic invader in Europe and Asia, where it forms dominant stands that can decrease species diversity. There is, therefore, an urgent need for effective management to reduce S. giga...

Plant succession is a well-studied phenomenon in plant ecology, yet the effects of disturbance and its influence on initial plant composition received little attention in this process. From many of the potential reasons we investigated the effect of soil fungi on early succession. At each site a total of 60 permanent plots were established and fung...

Giant goldenrod (Solidago gigantea) significantly reduces species diversity by forming dense monocultures in its invaded range. Solidago is one of the most aggressive invasive neophytes in Central Europe. The plant occupies mainly wet habitats but can also take over semi-dry and disturbed areas. It spreads long-distance by seed dispersal and locall...

Background: The adobe bricks of old buildings can preserve diaspores of cultivated and weed species associated with arable fields. Recovery of these plant remains can provide insight into historical agriculture, and former weed flora. Aims: This study aims to describe and evaluate the changes in the weed flora in south-western Hungary, based on arc...

With the increasing sophistication of paleoethnobotanical methods, it is now possible to reconstruct new aspects of the day-to-day life of past peoples, and, ultimately, gain information about their cultivated plants, land-use practices, architecture, diet, and trade. Reliable identification of plant remains, however, remains essential to the study...

Earth buildings are among the richest sources of archaeobotanical materials from the recent past. Thus, mudbrick constructions are extremely rich in plant materials, especially chaff, straw, fruits and seeds. Recovery of these remains enables us to gain a comprehensive insight into the contemporary floras of past settlements and their surroundings....

Based on the abundant archaeobotanical findings and the Nationwide Weed Surveys, the weed vegetation of Hungary is especially explored in Europe. However, only little is known about the weed flora of the period between the late middle ages and the Second World War. Examination of plant content of natural building materials (e.g. earth, mud and adob...

A földépítészet, így a vályogépítés is több ezer éves múltra tekint vissza az emberiség történetében, Magyarországon azonban csak a 17. században vált jelentősebbé. A vályogépítéssel az építészet és néprajz is sokat foglalkozott az elmúlt évtizedekben, a régi vályogtéglák ugyanakkor a botanika számára is érdekes vizsgálati objektumnak tekinthetők....

Vineyards are among the most intensively cultivated agricultural areas. The weed vegetation of vineyards in certain Hungarian regions is still lacking in detailed descriptions. The environmental and management factors have a great impact not only on the quality of the vine grape but also on its weed flora. Therefore it is impossible to determine wh...

Most of Hungarian vineyards can be found in wine-districts with different ecological conditions. The environmental factors have a great impact not only on the vine grape but also on its weed flora. Therefore it is impossible to determine what kind of weed communities are generally characteristic for certain vineyards, respectively which are the mos...

Segetal weed vegetation in Hungary has changed greatly in recent decades, mainly through diversity decrease of arable field flora. Our research was carried out in Southwestern Hungary, within the frame of the Fifth Nationwide Arable Weed Survey, between 2007 and 2008. In total 720 relevés were collected in four periods. Cereals, stubble fields and...

In this study floristic records of endangered and other interesting weed species are published from the Southern Transdanubian region. Our data were collected between 2000-2009 from arable fields, vineyards and ruderal habitats. The enumeration enlists the occurrences of earlier described/recently confirmed data, and also our new findings. 172 plan...

The aim of our research is to detect changes in weed composition on the basis of three nationwide weed surveys in Baranya county. We conducted our field work within the frame of the Fifth Nationwide Arable Weed Survey, between 2007 and 2008 and compared our results to the datasets of the second (1969-1971) and third (1987-1988) surveys. Comparing t...
