A set of medium-scale historical maps was used to reconstruct changes in spatial patterns of forest area during the last 220 years in an agricultural matrix of north-eastern Europe (Zemgale region, Latvia). Changes in total forest area by soils were determined, as well as the time period of continuous forest cover. Proportion of protected area for each soil trophic group was also calculated. Patterns of recent forest development differed between soil trophic groups. Afforestation occurred mainly on wet and poor soils in the 19th and 20th centuries, while the proportion of woodland area on fertile soils typical for nemoral forests was fairly stable. Only 1% of the fertile soil area has been covered by continuous forest for more than 220 years, and only 11% of them are protected. Nemoral deciduous forests cover only 15% of their potential natural vegetation area of forested eutrophic soils. Therefore, in regard to habitat protection that is representative of natural distribution of ecosystems, priority in conservation should be given to forests on fertile soils.

The species richness pattern exhibits a strong altitudinal dependence which may be altered under the influence of land use-related disturbances. The Beskid Niski Mountains are part of the northern Carpathian Mountains – an area that saw a large-scale relocation of certain ethnic groups after World War II. The subsequent rapid decline in the human population level was the main factor shaping the environment in this area, and contributed to a rapid increase in the forest area, also introducing changes in its functioning. The increase in the forest area was not evenly distributed, showing the largest values at higher locations. The present study is focused on changes in the species richness of the Carpathian fir forests along the altitudinal gradient, in relation to socio-economical transformations. The changes indicated an overall decrease in species richness, especially at higher locations. The main reason for these changes seemed to be forest management-related, causing an increase in the share of blackberry, fern and grass species, as well as the disappearance of species diagnostic of the ancient forests, which led to homogenization of vegetation. The increase in the mountain forest area has proven to be insufficient to secure the species richness of forests.

The study was carried out in central and north-eastern Poland in order to assess bat occurrence in small winter roosts located in house-cellars, in relation to the share of the surrounding landscape taken by forest cover and the distance separating the different sites from forests of at least 1 km². Data from single checks in 2243 cellars in 1990–2007 revealed a positive relationship (R² = 0.33, P <0.001) between the percentage of cellars occupied by bats and the forest cover (range: 2–58%) in sections of surrounding landscape covering between 30 and 220 km². Forest cover in the landscape within 1 km of the cellar appeared to have a slight influence on the number of species and species diversity (Simpson’s index; respectively R² = 0.14, P = 0.006 and R² = 0.13, P = 0.011). Both number of species and species diversity were progressively lower with increasing distance from the nearest forest covering an area of 1 km² or more (for both R² = 0.15, P = 0.005). Myotis nattereri (Kuhl, 1817) and Barbastella barbastellus (Schreber, 1774) were significantly more likely to colonise the cellars surrounded by landscape with a higher level of forest cover (P = 0.001 and 0.031), while M. nattereri was also more likely to be found in those at shorter distances from forests (P = 0.005). No such relationships were reported for either Plecotus auritus (Linnaeus, 1758) or Myotis daubentonii (Kuhl, 1817).

Timer decay is caused by primarily enzymatic activities of microorganisms. For the first time fungal diversity of timber degrading fungi was studied in Gujarat, India. Timber Degrading Fungi belonging to Aphyllophorales are economically important as many of these cause serious damage in sawmills of Gujarat. To find out the association of the timber degrading fungi and timber decay problems in sawmills a survey was conducted during 2007 to 2011 in different sawmills of 5 districts of Gujarat i.e. Vadodara, Ahmedabad, Bharuch, Rajkot and Jamnagar. In the present study teak wood present in sawmills was infected with 14 types of fungi in which Lenzites sterioides and Trametes versicolor damaged the wood severely was reported for the first time. In all 94 sawmills were surveyed, the 28 sawmills were from Vadodara, 29 from Ahmedabad, 12 from Bharuch, 21 from Rajkot and 4 from Jamnagar. Out of 94 sawmills survyed, 84 sawmills were having timber rotting fungi associated with wood. Maximum fifteen and thirteen fungal species were observed in saw mills of Chhani road, followed by 11 in Station road, 7 in Dhabhoi road and 6 in Harni, Vadodara. Fours woods uninfected are Beyo, Marinty, Ash, and Arjun. Fourteen different types of fungi were found associated with teak, followed by seven in pinus, madhuca, Acacia nilotica, six in babul, neem, four in tamarind, Pithacoelobium and three in mango, Eucalyptus, African Mahagoni, Kapoor, Peltophoram rouxburghii, Derris pinnata wood respectively. The commonly observed timber decaying fungi were Schizophyllum commune, Flavodon flavus and Ganoderma lucidum belonging to Basidiomycota. Ascomycota members included was Daldinia concentrica and Xylaria polymorpha.

Using data from the National Wolf Census, carried out in Poland in 2000–2001, and GIS techniques we analysed habitat selection by wolvesCanis lupus Linnaeus, 1758 in uplands and mountains of southern Poland. We compared ten habitat variables and two parameters related to wolf abundance in 52 circular plots (154 km2 each) with recorded wolves and 97 randomly selected plots with no signs of wolf presence. Wolf plots were characterized by higher elevation and closer location to the state border than wolf-free plots. Furthermore, wolf plots had higher forest cover, but smaller number of villages and towns and shorter railways and roads than plots without wolves. The best model explaining wolf distribution included forest cover, number of villages, length of roads and railway lines. Compared to northern Poland, the southern part of the country offers worse habitats for wolves due to significantly denser network of settlements and transportation routes.

Distribution and occupancy of setts by badgers Meles meles (Linnaeus, 1758) were surveyed in Białowieża Primeval Forest (1450 km ), one of the best preserved temperate lowland forests in Europe, in 1946-1961 and 1979-1999. In the Belarussian part of BPF in 1946-1951, badger density was estimated as 0.33 setts and 1.27 individuals/10 km . After predator control in the late 1950s, the number of active setts decreased to 0.09/10 km2 in 1961. Since the 1970s, badger population has been recovering; in 1979-1999, it averaged 0.16 setts and 0.61 ind/10 km . In Lhe Polish part of BPF, where badgers were not hunted, the densities in 1996-1999 were estimated as 0.41 setts and 1.57 ind/10 kra . I n the whole BPF, badger main setts were spaced regularly, with the nearest neighbour distance between active setts varying from 2.2 to 13.3 km (mean = 5.3 km, SD = 2.1). Surveys of 21 main setts during 1979-1999 (totally 171 sett-years) revealed that badgers occupied the setts in 68.4% of cases, raccoon dogs Nyctereules procyonoides in 12.9%, and red foxes Vulpes vulpes in 7%. Joint utilisation of the same setts by badgers and raccoon dogs was recorded in 5.3% of cases. Reviewing the literature on badger densities in 35 localities in the Palaeartic region showed that badgers attained rather high densities on the British Isles (14.9 setts/10 km , range 1.1-45.5; and 93.8 ind/10 km , range 8.6-307.0) compared to continental Eurasia (1.7 setts/10 km2, range 0.4-6.5; and 6.3 ind/10 km2, range 1.6-15.2). The number of badgers inhabiting a sett increased with log density of setts. Densities of badger setts did not depend on latitude but were negatively correlated with forest cover (p = 0.22, p - 0.008). We proposed that the biological mechanism behind this relationship was the higher biomass and availability of earthworms in open pastures and grasslands than in forests.

Celem pracy było określenie zróżnicowania flory wzdłuż wybranych szlaków pieszych zlokalizowanych w zbiorowisku żyznej buczyny karpackiej na terenie Ciężkowicko-Rożnowskiego Parku Krajobrazowego. Badania terenowe i kameralne przeprowadzono w latach 2006–2012. Każdego roku wykonano 700 zdjęć fitosocjologicznych zarówno wzdłuż szlaków turystycznych, jak i wewnątrz zbiorowiska leśnego. Wyniki badań wykazały, iż w obu strefach badawczych dominują gatunki leśne z klasy Querco-Fagetea. Z kolei udział roślin ze zbiorowisk trawiastych z klasy Molinio-Arrhenatheretea oraz synantropijnych z klas Stelarietea mediae i Artemisietea vulgaris był większy wzdłuż szlaków turystycznych niż wewnątrz buczyny karpackiej. Stwierdzono, iż presja turystyczna ma wpływ na kształtowanie się flory wzdłuż wybranych szlaków pieszych.

The paper is a review and it focuses on the most important factors responsible for the process of colonization of recent, post-agricultural woods by woodland species. Furthermore, it presents the results of the studies on habitat conditions and on the pace of the colonization by woodland herbs of post-agricultural black alder woods in the Oleśnica Plain and Żmigród Valley. Migration of woodland species into recent woods is a combined result of dispersal and recruitment limitation. However, in alder woods the herb layer recovery proceeds faster than in forests with lower fertility and moisture content. An important condition for the effective formation of understory in alder woods is the direct proximity of ancient forests, the establishment of shady conditions and the maintenance or restoration of natural high water levels. A high groundwater level suppresses the negative impact of competitive species, which otherwise develop vigorously in drained, eutrophic woods with a high illumination level on their forest floor. A better understanding of the mechanisms responsible for the biotic diversity of forests is possible due to the knowledge of their history, especially when we know the length of their existence in the landscape.
