In the years 1994-1996 macrofungi on two permanent plots situated in the phytocoenoses of <i>Galio-Carpinetum typicum</i> and <i>Galio-Carpinetum corydaletosum</i> in the "Dębina" reserve near Wągrowiec were monitored. 213 fungal taxa were found, mainly <i>Agaricales</i> (165 saprotrophic. 43 mycorrhizal and 5 parasitic fungi). Comparison of the results with the mycocoenological observations made 30 years ago revealed significant quantitative and qualitative changes in the ecological groups of macromycetes.

Mycosociological observations were carried out between 1994-1996 on permanent plots within a <i>Tilio-Carpinetum</i> association in the Białowieża National Park. The project was carried out with international cooperation within the "Mycological monitoring in European oak forests" programme which was a result of multiple signals concerning the disappearance of oaks in our continent. Almost 40 years before mycosociological research in the same plant association and at the same plots were carried out. Studies were mainly concerned with analysing the terrestrial macromycetes, predominantly <i>Boletales</i> and <i>Agaricales</i>. They analysed the occurrence of saprotrophic and mycorrhizal fungi. Totaly 215 species from the above listed ecological groups, but there were only 34 species common to both studies. Dominating species within the mycorrhizal group were found.

<p>The mycology of peatlands, with their specific plant communities and numerous rare plant species, has been underexplored and is poorly recognized. The main objectives of this study were to identify the species richness and diversity of macromycetes in raised and transitional bogs of Pomerania and to establish correlations between macroscopic fungi and peatland communities occurring in the area in view of environmental conditions. Investigations spanning a period of ten years were conducted at 134 sites (71 raised and 63 transitional bogs) in eight non-forest peatland communities (<em>Caricetum lasiocarpae</em>, <em>Caricetum limosae</em>, <em>Caricetum rostratae</em>, <em>Eriophoro angustifolii-Sphagnetum recurvi</em>, <em>Rhynchosporetum albae</em>, <em>Erico-Sphagnetum medii</em>, <em>Sphagnetum magellanici</em>, and the <em>Eriophorum vaginatum-Sphagnum fallax</em> community) and two forest communities (<em>Vaccinio uliginosi-Pinetum</em> and <em>Vaccinio uliginosi-Betuletum pubescentis</em>) in which 108 permanent observation plots were established for detailed examinations. A total of 191 macromycete species were recorded in the peatlands. The smallest number of species was recorded in <em>Rhynchosporetum albae</em> (12 species) and <em>Caricetum rostratae</em> (15 species). Phytocoenoses richest in fungi were <em>Vaccinio uliginosi-Pinetum</em> (102 species) and <em>Vaccinio uliginosi-Betuletum pubescentis</em> (121 species). The number of macromycete species recorded in individual peatland communities depends on the community type and is not conditioned by the number of observations and the number and the total area of permanent plots. Five mycosociologico-ecological groups of macroscopic fungi were distinguished based on numerical analyses. Four groups comprise species of fungi associated with a specific phytocoenosis or a group of phytocoenoses. One group consists of fungi with a broader ecological scale. The majority of environmental variables representing the substrate’s chemical properties, humidity and pH show a statistically significant influence on the diversity of macroscopic fungi species in the peatland communities. Cartogram maps of the distribution of 21 species of peatland fungi are included and geographico-ecological features of the species are briefly described.</p>

The densities of adults of the Australian plague locust (Chortoicetes terminifera (Wlk.) were estimated in a network of permanent plots in part of the Bogan-Macquarie outbreak area from 1965 until early 1973. In that area, 2-3 generations are produced between September and April-May, depending on rainfall. C. terminifera is able to maintain a high rate of reproduction in this area. The numbers of adults produced in one generation are directly related to the total rainfall during a period of three weeks at the time of hatching and can be predicted by a linear regression of adult numbers on rainfall. The evidence suggests that rain favours the survival of nymphs immediately after hatching by influencing the growth of food-plants. The ecological factors that cause discrepanices between the observed numbers and those predicted by regression are discussed. Among these are immigration, qualitative changes such as the development of hopper bands and the build-up of natural enemies, combined with errors in the selection of suitable oviposition sites by the locusts themselves. Despite intermittent droughts, the range of fluctuation of numbers of C. terminifera is limited in this region, and in the long term average numbers are high.

The changes in floristic composition, richness, species diversity and ecological groups of a semideciduous seasonal forest located at 14°49′32″S 52°06′20″W in the Cerrado–Amazonian Forest transition, in the area of Nova Xavantina, eastern Mato Grosso, Brazil, were determined between 2003 and 2008. Sixty permanent plots of 10 × 10 m were established, where the individuals with diameter at breast height (dbh) ≥ 5 cm were recorded and identified. The changes in floristic composition over the period were small and species losses and gains were limited to those of low abundance. The species richness and diversity did not change during this period and observations over a longer period will be necessary to determine whether it is a static community or in a succession towards the relatively nearby Amazonian forests. A review of existing works on the transition forest of Mato Grosso is also given.

Aim of the study: To assess structure, recruitment and mortality rates of tree species over almost three decades, 14 years before and 15 years after a forest fire. Material and methods: All trees ≥ 5 cm in DBH were identified and measured in 12 permanent plots (50 m x 50 m), in 1983, 1987, 1989, 1995, 2008, and 2012 of a dense ombrophilous forest in Eastern Amazon, Brazil. The analyses were carried out including all sampled species and their ecological groups: shade-tolerant, light-demanding, and pioneer species. Treatments were compared through a Linear Mixed Effect Model. Main results: The 15-year post-fire period is not enough for the old-growth tropical forest to recover its pre-fire conditions of recruitment and mortality rates. The post-fire recruitment and mortality rates increased, mainly the recruitment of pioneer species (p-value < 0.05). Research highlights: In a period of 15 years after the occurrence of a surface fire, the old-growth tropical forest still has high recruitment rates of shade-tolerant and light-demanding species and high incidence of pioneer species, confirming the persistent fire effects on forest dynamics and species composition in this ecosystem.
