Megjegyzések: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 policy makers. We used the possible future statements from the Hungarian Environmental Foresight Report for 2050 which identified region-specific problems. To highlight likely future environmental and conservation questions, in this study we asked researchers from the fields of ecology and conservation to define research questions addressing these future statements in line with international research trends and challenges. The study resulted in fourteen priority research topics, split into seven clusters relevant to biological conservation that should be targeted by stakeholders, primarily policy makers and funders to focus research capacity to these topics. The main overarching themes identified here include a wide range of approaches and solutions such as innovative technologies, involvement of local stakeholders and citizen scientists, legislation, and issues related to human health. These indicate that solutions to conservation challenges require a multidisciplinary approach in design and a multi-actor approach in implementation. Although the identified research priorities were listed for Hungary, they are in line with European and global biodiversity strategies, and can be tailored to suit other Central and Eastern European countries as well. We believe that our prioritisation can help science?policy discussion, and will eventually contribute to healthy and well-functioning ecosystems.

Cím:Grassland restoration benefits declining farmland birds: A landscape-scale before-after-control-impact experiment / Szabolcs Lengyel, Gergő Nagy, Máté Tóth, Gábor Mészáros, Csaba P. Nagy, Edvárd Mizsei, Márton Szabolcs, Béla Mester, Thomas O. Mérő

Megjegyzések:The decline of farmland bird populations starting in the 1980s has induced intense research on farmland biodiversity conservation in Europe. Although many studies assessing the effectiveness of agri-environmental schemes have concentrated on birds, farmland birds, surprisingly, have not yet been targeted directly by permanent, landscape-scale restoration of grassland ecosystems on former croplands in Europe. We compared farmland bird responses to grassland restoration by grass sowing, alfalfa sowing followed by spontaneous grassland recovery, and hay transfer (impact sites) with responses to extensive, low-intensity cropland cultivation (controls) in a Before-After-Control-Impact design, and also compared extensive croplands against a baseline reference of intensive croplands. Point counts in 69 sites on 910 ha in at least two years before and three years after the interventions showed that farmland bird species richness increased in both restored grasslands and in extensive croplands, whereas abundance and Shannon diversity increased only in restored grasslands but not in extensive croplands. Abundance increased in restored grasslands for five farmland species and two species of conservation importance, and in extensive croplands for one farmland and one species of conservation importance. Active restoration by grass sowing increased both species richness and diversity and active restoration by hay transfer increased abundance, while passive restoration targeting spontaneous grassland recovery after alfalfa sowing increased richness and abundance. Extensive croplands had four-five times more species and individuals than intensive croplands. Our results suggest that landscape-scale grassland restoration can locally reverse regional farmland bird declines and can thus be a promising tool in farmland biodiversity conservation.

Cím:Spatiotemporally variable management by grazing and burning increases marsh diversity and benefits amphibians: A field experiment / Mester Béla, Szalai Mónika, Mérő Thomas Oliver, Puky Miklós, Lengyel Szabolcs
Dátum:2015
ISSN:0006-3207
Megjegyzések:Ecosystem management often aims to maintain a diversity of habitats to benefit a large number of species within a landscape. We studied the effects of wetland management by low-intensity cattle-grazing and late-summer burning on marsh vegetation and globally declining anuran amphibians (frogs and toads) in a previously homogeneous reedbed. Burning effectively removed old reed and increased the variability of reed cover and marsh vegetation by the next spring. However, reed grew back strong in areas burned 2 or 3 years before the study, indicating that fire rejuvenates reedbeds. In contrast, cattle-grazing kept reed cover homogeneously low and created open water surfaces. The number of amphibian species and individuals decreased with mean reed cover and old reed density, and increased with variability in reed cover. Correspondingly, amphibian richness and counts were greatest in newly burned areas the next spring. In contrast, a year later, richness and counts were greatest in grazed-only areas, with large decreases in newly burned and control areas. Our results suggest that combined management with grazing and burning can create different habitat patches, some of which will be optimal for amphibians in one year, whereas other patches may become suitable in a subsequent year when successional changes alter previously optimal patches. To maximize optimal habitats, mosaic management should repeat burning once every 2 or 3 years in a rotational manner, and also maintain low-intensity cattle-grazing, which controls reeds and benefits amphibians more sustainably. Our study supports spatiotemporally varied management to facilitate habitat heterogeneity and complexity in dynamic landscapes.

Cím:Restoring grassland biodiversity : Sowing low-diversity seed mixtures can lead to rapid favourable changes / Péter Török, Balázs Deák, Enikő Vida, Orsolya Valkó, Szabolcs Lengyel, Béla Tóthmérész
Dátum:2010
Megjegyzések:We studied the effect of sowing low-diversity seed mixtures (containing 2-3 competitive grass species)on the regeneration of vegetation on croplands previously used as alfalfa fields. In four permanent plots in10 restored fields (four with alkali and six with loess seed mixture) the cover of flowering plants wasrecorded and phytomass was measured between 2006 and 2008. We asked three questions: (i) How fastwill weedy, short-lived species decrease in abundance during secondary succession enhanced by sowinglow-diversity seed mixtures? (ii) Can weeds be suppressed by sowing competitive native grasses, followedup by management by mowing? (iii) Can succession towards the target native grasslands be acceleratedby sowing only low-diversity seed mixtures compared to set-aside old field succession? Ourresults showed that in just two years a vegetation dominated by perennial grasses has developed, whichsuccessfully prevented the establishment of weed species. These results suggested that sowing seeds oftwo or three competitive grass species is an effective tool to eliminate weed domination and to leadtowards the restoration of species poor grasslands with grass domination such as alkali grasslands. However,the developed dense perennial grass cover and the accumulated litter may hamper the immigrationof specialist species characteristic to reference grasslands. Therefore, the restoration of species-rich grasslandsrequires the facilitation of the immigration of grassland specialist species by further management(grazing, mowing and/or hay-transport).
