Abstract Photo observations are a highly valuable but rarely used source of citizen science (CS) data. Recently, the number publicly available photo has increased strongly, for example, due to use smartphone applications species identification. This enabled raising ecological insights in poorly studied subjects. One fields with highest potential benefit from is phenology. We propose workflow iPhenology, track phenological events at large scales. The comprises data acquisition, cleaning...
The nitrogen‐fixing legume Lupinus polyphyllus invaded semi‐natural mountainous grasslands across Europe during the last decades. This invasion resulted in degraded habitats through changes structure and function of mountain meadow vegetation. In our study, we analyzed (1) effects increasing cover L. on seed bank meadows, (2) potential these stands for active restoration meadows terms species composition number . We conducted a analysis 84 plots with three mountain‐meadow types Rhön...
The invasive herb Lupinus polyphyllus has been focus of a number fact sheets worldwide but comprehensive summary the species' taxonomy and morphology, distribution, habitat requirements, biology lacking. This paper gives thorough account systematic position taxonomy, highlighting difficulties to delimit taxa, which is related interbreeding among members this genus. However, L. var. apparently taxon that naturalized regionally in temperate-humid climates worldwide. We also present an updated...
Restoration of floodplain meadows remains a challenge, as many degraded sites suffer from seed limitation. The transfer seed-containing plant material species-rich donor is widely used method to restore semi-natural grasslands. However, most studies on the success such restoration projects comprise limited time frames. As factors determining may only become evident after years, long-term observations are crucial. We re-investigated 20 restored grassland in Northern Upper Rhine 13–16 years...
In Central Europe, species-rich grasslands have strongly diminished over the last century. The transfer of seed-containing plant material from donor sites with a desired species composition to restoration is well-established method restore grasslands. Despite plethora available literature, projects often fail or do not reach planned goals. Practitioners' knowledge highly important but underexplored source information on factors deciding about success projects. At same time, it unclear which...
In semi-natural grasslands, mowing leads to the dispersal of species that have viable seeds at right time. For invasive plant in by should be avoided, and information on effect cutting date germination is needed. We investigated legume Lupinus polyphyllus Lindl. depending date. measured seed traits associated with successful can assessed managers for an improved timing control measures. To this end, we sampled L. six dates analyzed these climate chambers under ambient weather conditions....
Plant phenology, i. e. the timing of life cycle events, is related to individual fitness and species distribution ranges. Temperature one most important drivers plant phenology together with day length. The adaptation their may be for success invasive species. present study aims at understanding how performance legume Lupinus polyphyllus vary latitude. We sampled data across a >2000 km latitudinal gradient from Central Northern Europe. quantified variation in flowering fruiting L....
Abstract Aim We assessed the role of mowing machinery and endozoochory by migratory sheep as dispersal vectors in semi‐natural grasslands comparing species compositions traits found to regional above‐ground vegetation soil seed bank. Furthermore, we discuss how their interplay may affect conservation grasslands. Location Rhön Mountains, central Europe. Methods Plant material from mowers ( n = 12 one date) dung samples 39 13 dates) were collected dispersed plant determined using emergence...
Semi‐natural grasslands invaded by the legume Lupinus polyphyllus need introduction of target species in order to promote highly endangered native plant communities. However, which techniques are best suited achieve both invader control and at same time? Few studies have investigated restoration that support communities mountain meadows simultaneously. We employed seed bank activation green hay transfer combination with manual removal invasive L. on three types grassland ( Nardus grassland,...
Seed rain, the amount of seeds reaching an area via primary or secondary dispersal, affects regeneration plant communities and shapes trajectory future community composition. In agricultural grasslands, composition density in seed rain are mainly driven by land use, but drivers quality quantity along land-use gradients poorly understood. We studied effects intensity (LUI), its components (i.e. fertilization, mowing, grazing), productivity, aboveground vegetation richness on rain. collected...
