Pilgerodendron uviferum (D. Don) Florin is an endemic, threatened conifer that grows in South America. In the sub-Antarctic territory, one of the most isolated places in the world, some forest patches remain untouched since the last glaciation. In this study, we analyze the tree structure and tree diversity and characterize the environmental conditions where P. uviferum-dominated stands develop within the Magellanic islands in Kawésqar National Park, Chile. An environmental matrix using the databases WorldClim and SoilGrids and local topography variables was used to identify the main environmental variables that explain the P. uviferum-dominated stands. PCA was used to reduce the environmental variables, and PERMANOVA and nMDS were used to evaluate differences among forest communities. The results show that two forest communities are present within the Magellanic islands. Both forest communities share the fact that they can persist over time due to the high water table that limits the competitive effect from other tree species less tolerant to high soil water table and organic matter. Our results contribute to knowledge of the species’ environmental preference and design conservation programs.

Seasonal Aspects

The investigations on the role of macromycetes in various forest communities of the Świętokrzyski National ark were performed in the years 1964-1968. Fruit bodies growing on the soil, in the litter and on wood were studied on 13 permanent plots. Attention was paid to effects of atmospheric conditions on the fruiting of fungi and to the seasonal aspects of macromycetes.

Phytosociological Relevés

Non-forest communities in the western part of the Kampinos National Park were studied in the years 1991 – 1998 with regard to their phytosociological diversity and dynamic processes currently underway in them. A total of 323 phytosociological releves were prepared by the widely used method of Braun-Blanquet. These releves served as basis for identification of 31 associations and 7 meadow and sedge communities of undetermined level. 15 syntaxa were recorded in the <em>Phragmitetea</em> class, 18 syntaxa – in the <em>Molinio-Arrhenatheretea</em> class, 2 associations in the <em>Scheuchzerio-Caricetea</em> class, as well as 3 grassland associations from <em>Koelerio glaucae-Corynephoretea canescentis</em> and <em>Nardo-Callunetea</em> classes. In order to determine the character and direction of changes in phytocoenoses, 4 basic ecological processes have been distinguished – fluctuation, degeneration, regeneration and secondary succession. Within secondary succession, recreative, creative and anthropogenically forced secondary succession were distinguished.

Germination Behaviour

AbstractAbies cephalonicacone and seed morphometric characteristics as well as seed germination behaviour were investigated during an 8-year-long diachronic study (2007–2015). The research was carried out in Parnitha National Park, in the part of this Greek endemic, silver fir population that was spared from an unprecedented wildfire (2007). A statistically significant interannual and among-tree variation of cone traits has been identified, except for cone diameter. Cone length is correlated to the number of seeds per cone, while the percentage of empty seeds has been consistently high, with extreme values of 29.3 and 81.8% in a masting (2015) and lean crop (2009) year, respectively. There is also a considerable proportion of dead (including infected) and non-germinated seeds, and the eventual germinable fraction is well below 25% with spikes in masting years (39.4 and 60.9% in 2010 and 2015, respectively). Untreated seeds have been tested at a wide range of constant and alternating temperatures and germination is completed within 4–5 weeks atT≥ 15°C andca15 weeks at 5–10°C. A chilling pretreatment of 4–8 weeks (at 2–4°C) concludes germination at 15–20°C within 2 weeks. A significant white light requirement has been observed for untreated seeds at 15–20°C, while germination was light indifferent at lower or higher temperatures. Data obtained in this study confirm the present, field seed germination during springtime; we may also predict an earlier germination (late autumn to mid-winter) in forest gaps, under the predicted, warmer conditions in the future.

Point Pelee National Park

The Emerald Ash Borer (EAB) is a wood-boring beetle native to Asia that now infests and kills ash trees (Fraxinus spp.) in North America. Many ecological communities will be dramatically altered by the mortality of ash trees caused by this invasive insect. The EAB recently colonized Point Pelee National Park of Canada in extreme southwestern Ontario, Canada, a site famous for its unusual plant and animal diversity as well as its extraordinary bird migrations. We conducted a census of breeding birds in two ash-rich mature forests at Point Pelee in order to obtain baseline data on the breeding bird communities prior to changes in forest communities that are likely to be caused by the EAB. Here we report the results of the bird census and review possible changes to the breeding bird fauna of Point Pelee that may result from ash tree mortality and the associated disruption of forest communities.

Compositional Changes

Ponderosa pine (Pinusponderosa Laws.) forest communities in Glacier National Park, Montana, were investigated to determine the effects of fire exclusion. Analysis of age data in these fire-dependent communities indicates that ponderosa pine is not reproducing itself as well as other mesophytic conifers invading these stands. In addition to these compositional changes, it was determined that fuel accumulations are greater in these park communities compared with similar wilderness area pine communities subject to more recent burning.
