Earlier reproductive phenology of restored grasslands
Abstract Introduction Plants introduced to degraded ecosystems during restoration efforts often face novel environmental conditions. Consequently, plant functional traits can differ between restored and reference sites, even within the same species. Studies on such intraspecific variation mainly focused on vegetative traits, while the timing of life ...

Abstract Micarea is a crustose cosmopolitan lichen genus that belongs to the euascomycete class Lecanoromycetes. Recent molecular phylogenies on the genus based on one to three loci have mostly focused on Micarea s.str., including the type species M. prasina, and suggested that Micarea s.l. is paraphyletic.

Reaction of Coniferous Forest Vegetation to Particulate Deposition Under Alkaline Pressure [PDF]
The aim of this study was to determine direction, rate and character of the changes in coniferous forest communities caused by anthropogenic stress factors (alkaline emission and imission) changing with time.

Most terrestrial plants are colonised by arbuscular mycorrhizal fungi but vary in the degree to which they benefit from and depend on these fungi. Here we show that plants can make the interaction with mycorrhizal fungi more beneficial to themselves by regulating the chemical composition of organic compounds released by plant roots into the soil ...

Fern spore dispersal: A methodological review and experimental field study
Abstract Spore dispersal is one of the most important but perhaps the least investigated and understood processes in determining the geographical distribution of fern species. After a methodological review of the aerobiology of fern spores, we examined the impact of spore characteristics and meteorological factors on their airborne dispersal.

Bedeutung der Megaherbivoren-Beweidung für die Renaturierung artenreicher Feuchtgrünländer auf ehemaligen Ackerflächen [PDF]
Species-rich wet grasslands in floodplains are on focus of European nature conservation policy. However, since the seventies of the last century large areas with grasslands in floodplains have been meliorated, ploughed and used for intensive cropping in ...

Investigation into the question of complex processing of bauxites of the srednetimanskoe deposit [PDF]
A new technology of processing raw materials with the use of active alkali is suggested for bauxites of the Srednetimanskoe deposit; bauxite is opened at 300°C for 1 h.

Animal‐mediated seed dispersal: A review of study methods
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

Secondary succession of overgrazed Pannonian sandy grasslands [PDF]
We assessed vegetation changes on acidic sandy soils in permanent plots to follow secondary succession after cessation of intensive goose breeding in E Hungary.We also aimed to estimate the time required for vegetation regeneration and indicate ...
