Analysis website

The analysis town consists of c. dos kilometres 2 regarding varieties-rich lifeless calcareous grassland inside the western Estonia (°Letter, °E). The fresh grasslands set up usually on account of long-term thorough administration, rather grazing from the residential dogs, collecting hay and reducing shrubs and you will woods getting stamina. , 1999 ). The latest grasslands usually got an optimum juniper (Juniperus communis) safeguards from 29%, however they are today even more overgrown which have Scots oak (Pinus sylvestris; around 80% cover).

Sampling construction

Testing is actually presented in the on web sites where consistently addressed (mown) discover grassland stands (GR) had been enclosed by really stands out of differing amounts of over growing: transformation grasslands (TR) and young oak woods (FO). The 3 successional levels (GR, TR, FO) mode a temporal sequence from regeneration sequence covering c. 60 yr, and are generally characterised by the a progressive over growing regarding unlock grasslands because of the bushes and you may woods, that’s normal to have abandoned calcareous grasslands from the studies part (Neuenkamp ainsi que al., 2016 ; Help Recommendations Fig. S1). During the transformation grasslands administration ceased c. 30–thirty-five year in advance of sampling and you can grasslands was basically partially overgrown of the oak and you may juniper; young oak forest were previous grasslands in which management stopped c. sixty yr in advance of testing and that have been completely overgrown by pine and you may juniper. An internet site is actually identified as a location in which the about three successional level were found contained in this 50 yards of every almost every other (GR–TR–FO). Completely, twenty five internet was sampled. A randomly located step 1 ? step one yards area is actually established in each successional phase (GR, TR, FO) of every web site, ultimately causing a maximum of 75 plots (twenty five internet sites ? around three successional amounts). The next features was indeed discussed for each and every area: industry coating plant society, Was fungal organizations (in plant origins, and you may rhizosphere crushed) and you can environment details.

Data collection

For each 1 ? 1 meters plot, all the vascular bush varieties on floor-coating people were filed and their wealth was estimated just like the fee defense (Peet & Roberts, 2013 ). At the same time, percentage defense prices out of shrubbery and woods contained in this a great 10 ? 10 yards city up to for every single spot were recorded. Hereafter, the floor-level bush neighborhood is referred to as ‘bush community’ and all analyses try used using this type of people except if expressed otherwise.

An effective 10 ? ten ? ten cm crushed center are accumulated throughout the heart of any patch and you may bush sources had been split regarding soil, dehydrated to have twenty four h within 50°C and you can held dry for additional unit studies off options-colonising Was fungus. Are fungal assortment in plant roots ended up being analysed from mixed options products. Sources within the per take to was crushed playing with liquid nitrogen and you can carefully blended as described because of the Garcia de- Leon mais aussi al. ( 2016 ). Good subsample regarding 70 milligrams of every combined sources shot is actually useful unit analyses.

Bush groups have been demonstrated within a bigger spatial measure compared with In the morning yeast groups, that size is always to approximately mirror the latest bush means area caught from the an excellent ten ? ten ? ten cm crushed center. Small-size plant range within the grasslands was large underground than over crushed (Hiiesalu mais aussi al., 2014 ), partially while the spacious root system and you will long rhizomes of many grassland vegetation link brand new origins present in a localised soil key with significantly more than-ground body organs increasing 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).
