Figures & Tables

Fig 1.

Map with the location of the sampling site and meteorological station. In the inset is shown the location of the sampling site in Poland.

Fig 2.

(A) Amount of pine deadwood removed from the forest before and after drought in 2015; (B) Mean monthly values of precipitation and maximum monthly temperatures (with a fitted smoothing spline line) for the vegetation period (April–October) (data from the Opole meteorological station (IMGW-PIB, 2022)).

Fig 3.

Representation of anatomical features as LA and CWT. CWT, cell wall thickness; LA, lumen area.

Fig 4.

(A) RWI chronology for healthy and declining trees; (B) Comparison of mean RWI values for two groups of trees (healthy and declining) in two time periods. RWI, Ring Width Index.

Fig 5.

Static correlation coefficients for the relationship between relative humidity, maximum temperature, mean temperature, mean monthly precipitation, SPEI and RWI chronologies for declining and healthy trees. Months in lowercase refer to the previous year, while months in uppercase refer to the current year. The point represents the mean correlation, while the error bar represents the 95% confidence interval of the correlation based on 1000 bootstrap samples (Zang and Biondi, 2015). RWI, Ring Width Index; SPEI, Standardised Precipitation–Evapotranspiration Index.

Fig 6.

Comparison of: (A) mean LA and (B) mean CWT values for two groups of trees (healthy and declining) in two time periods. CWT, cell wall thickness; LA, lumen area.
