“…Both causes also explain why specialisation in abandoned fields decreased during succession. It is generally known that at the beginning of succession in abandoned fields numerous but rare archaeophyte weeds may occur but disappear quickly (Osbornová et al, 1990). Similar trends were seen in the other secondary successions, that is in burnt forests and fishpond islands and barriers (the latter seres can be considered to be intermediate between primary and secondary succession because organic substrate with diaspores may prevail — see Prach et al, 2016): in burnt forests, some early species adapted to forest clearings occur (Adámek et al, 2015), in the fishpond habitats, species typical of exposed pond bottoms are often present (Šumberová et al, 2006).…”

QuestionsConservation and restoration efforts can greatly benefit from understanding how plant community specialisation changes after disturbance. This paper addresses general successional patterns concerning the following questions: How does community specialisation change during succession? What are the general patterns in the occurrence of generalists and specialists? What are the general ecological strategies of generalists and specialists? Are threatened species better represented among specialists, as generally expected?LocationCzech Republic, central Europe.MethodsWe assessed trends in plant community specialisation as well as the participation of generalists and specialists in 12 types of successional series based on a large data set of dated plots of spontaneously established vegetation at various disturbed sites. We classified species into generalists and specialists using a co‐occurrence specialisation metric, determined overall community specialisation at the plot level, and assessed trends in response to successional age for each of the seres using regression analyses, community‐weighted means and the fourth‐corner approach. We also examined the differences between generalists and specialists during succession by comparing their ecological strategies (competitive, stress‐tolerant and ruderal) and conservation status.ResultsCommunity specialisation generally increased during succession, mainly due to a decline in generalists and an increase in typical species of particular habitats such as grasslands, woodlands and wetlands. Despite the general increase in community specialisation, specialists peaked in early and old successional stages and were always less abundant than generalists. During succession, generalists were more stable in their ecological strategies and were predominantly competitive. Specialists varied more, being mostly competitive stress tolerators but also ruderals in early successional stages. Specialists were proportionally more threatened than generalists.ConclusionsGeneralists and specialists differ in their successional patterns, ecological strategies and conservation status. Assessing the spatio‐temporal changes in community specialisation helps to evaluate and track successional trends, and to determine the conservation and restoration status of degraded areas.

The effect of plant species diversity on productivity and competitive ability was studied in an experiment carried out simultaneously in five European countries: Czech Republic (CZ), the Netherlands (NL), Sweden (SE), Spain (SP), and United Kingdom (UK). The aim was to separate the 'chance' or 'sampling effect' (increasing the number of sown species increases the probability that a species able 'to do a job' will be included) from the complementarity effect (species-rich communities are better able to exploit resources and to take care of ecosystem functions than species-poor communities). In the experiment, low diversity (LD) and high diversity (HD) mixtures of grassland species were sown into fields taken out of arable cultivation. The HD mixture consisted of five grass species, five legumes and five other forbs. The LD mixtures consisted of two grasses, one legume and one other forb, with different plant species combinations in each replicate block. The design of the experiment was constructed in such a way that the total number of seeds of each species over all the replications was exactly the same in HD and LD treatments, and the total number of grass seeds, leguminous seeds and other forb seeds were the same in both LD and HD. The responses measured were the total above-ground biomass (as a measure of productivity) and the average number of naturally establishing species in a plot (as a measure of the competitive ability of the mixture), both measured in the third year of the experiment. The results show that, on average, the HD plots performed better (i...

Aththorick TA, Setiadi D, Purwanto Y, Guhardja E. 2012. Vegetation stands structure and aboveground biomass after the shifting cultivation practices of Karo People in Leuser Ecosystem,. Vegetation stands structure and aboveground biomass after the shifting cultivation practices of Karo People in Leuser Ecosystem, North Sumatra. Shifting cultivation has been practiced by Karo People in Leuser Ecosystem for a very long time and caused a mosaic of patches that shift over time between traditional agriculture and secondary forest. The objectives of this study were to investigate the recovery of vegetation stands structure and aboveground biomass in four age classes of secondary forest, i.e. 5-years old, 10-years old, 20-years old, 30-years old and primary forest as a control. In total, 496 subplots were surveyed. Saplings contributed 62.82% of basal area in 5-years forest and still important in 10 and 20-years forest, but density decreased in 30-years and primer forest whereas tree stands dominated in 30-years and primary forest and shared basal area of 96.36% and 97.03%, respectively. Aboveground biomass of trees achieved its highest values in primary forest, i.e. 659.22 t/ha and contributed to total aboveground biomass of 99.38%.
