Data webpages

The research area includes c. dos kilometres dos out of variety-rich dry calcareous grassland during the western Estonia (°Letter, °E). Brand new grasslands install typically due to much time-title detailed management, significantly grazing from the residential pets, meeting existe and reducing bushes and you will trees to own strength. , 1999 ). The latest grasslands traditionally got a max juniper (Juniperus communis) shelter away from 31%, but are now all the more overgrown that have Scots oak (Pinus sylvestris; as much as 80% cover).

Sampling build

Sampling are presented into the during the websites in which constantly handled (mown) unlock grassland really stands (GR) was indeed surrounded by stands of different amounts of overgrowth: transitional grasslands (TR) and you will younger pine forests (FO). The 3 successional grade (GR, https://datingranking.net/cs/beetalk-recenze/ TR, FO) form a temporal sequence away from regeneration series covering c. sixty year, and generally are characterised because of the a progressive over growing away from unlock grasslands because of the shrubs and woods, that is typical to possess quit calcareous grasslands throughout the studies part (Neuenkamp ainsi que al., 2016 ; Supporting Advice Fig. S1). From inside the transformation grasslands government stopped c. 30–thirty-five yr ahead of testing and grasslands was basically partly overgrown because of the pine and you can juniper; younger pine woods was indeed former grasslands in which administration stopped c. 60 yr just before testing and you can which have been entirely overgrown by pine and you can juniper. An online site was defined as an area in which most of the around three successional degrees have been receive contained in this fifty yards of every most other (GR–TR–FO). Altogether, 25 internet was in fact tested. An arbitrarily discovered step 1 ? step 1 m plot is created in for each successional stage (GR, TR, FO) of each and every site, ultimately causing a maximum of 75 plots (twenty-five websites ? three successional stages). The following services was indeed described per plot: industry layer bush society, In the morning yeast communities (in-plant roots, and you may rhizosphere surface) and you may environment variables.

Data range

Per step 1 ? 1 meters plot, the vascular bush species in the floor-coating people was basically filed in addition to their abundance try estimated as fee coverage (Peet & Roberts, 2013 ). At the same time, commission cover estimates from shrubs and you can trees in this an effective ten ? 10 m urban area doing per spot was indeed registered. Hereafter, a floor-layer plant community is known as ‘bush community’ and all sorts of analyses was conducted using this people until shown or even.

An effective 10 ? ten ? 10 cm floor center try gathered about centre of every spot and bush root was basically split in the surface, dried having 24 h in the 50°C and you can held dry for additional molecular studies out-of supply-colonising Was fungus. Have always been fungal range in-plant root was then analysed out-of blended resources trials. Roots in per test have been crushed using water nitrogen and you can very carefully combined while the described by the Garcia de Leon ainsi que al. ( 2016 ). A subsample off 70 mg of every mixed sources take to was employed for molecular analyses.

Plant groups was basically described in the a larger spatial measure in contrast to In the morning fungal organizations, since this measure should as much as mirror brand new plant resources area caught from the an effective ten ? 10 ? ten cm floor core. Small-size plant range into the grasslands is higher underground than a lot more than surface (Hiiesalu mais aussi al., 2014 ), partially once the large resources system and you may a lot of time rhizomes of numerous grassland flowers connect the fresh roots present in a localised surface core which have over-ground organs broadening several ).

To characterise AM fungal diversity in the soil, 10 g of soil was collected from each soil core, dried with silica gel and stored airtight at room temperature. A second subsample of 10 g of soil was collected from each soil core for measuring the concentration of an AM fungal neutral lipid fatty acid fungal abundance in the soil. This second soil sample was freeze-dried for 15 h at ?80°C and stored airtight at room temperature. The remainder of each soil core was air-dried for analysis of soil chemical properties (pHKCl, Ntot, P, K, Mg, Ca, Corg) following International Organization for Standardization (ISO) protocols (see Methods S1).
