The aim of the research was to study 20-year changes in the floristic richness of the vegetation and soil diaspore bank of agroceonoses and adjacent midfield woodlots, as a result of the intensification of agricultural production, and the role of the ecotone in the preservation of field weeds. The studies were conducted in two periods, the first between 1996 and 1998 and the second between 2016 and 2018, on 12 permanent plots located in a transition zone between agroceonoses and woodlots. The width of the ecotone zone was determined with a linear transect that crossed both communities. The study of vegetation was conducted using the Braun-Blanquet method. During each period, soil diaspore reserves were determined. A large decrease of approximately 30% in the number of species was noted in the agroceonoses, while there were minor changes in the wood communities. With only slight variation during the research, floristic diversity of the soil diaspore bank in those habitats was poorer than vegetation diversity. The ecotone phytoceonoses had the highest species richness. They showed greater floristic similarity to the wood phytoceonoses than to agroceonoses. In the transition zone a clear boundary was observed, dividing those two communities. The ecotone was a refuge for field species, including rare and endangered ones. The species composition of the ecotone soil diaspore bank was poorer than the composition of the flora and showed greater similarity to the species diversity of the agroceonoses. Additionally, a significant relationship between species richness and habitat conditions was noted.

The current study was undertaken to determine long-term population trends (33 years) of ungulate species in the Waterberg National Park (WNP), Namibia, using aerial and waterhole counts of ungulates during the years 1980-2013.We tried to establish how rainfall influences the multi-species population dynamics. During this period sixteen ungulates species were recorded. Among these, eight have shown an increase in numbers during the years 1984-2013, six other decreased, and populations of two other species remained stable. Roan and sable antelope, kudu and warthog were fairly common (with 5-12% of all ungulates recorded). White rhino, black rhino, giraffe, and gemsbok were classified as uncommon (together 11.9%), whilst the remaining eight species were rare (together 1.9%). The eland population showed a weak positive relationship with the annual average rainfall between the years 1981-2013, whereas population sizes of kudu, sable, gemsbok and roan showed a weak negative relationship with the amount of rain. No relationship was detected in giraffe, buffalo and hartebeest populations. We conclude that, irrespective of water supplementation, ungulate densities are to a large extent controlled by rainfall.

The water bodies formed in forest complexes are characterised by a significant degree of isolation from other aquatic environments as well as from urban agglomerations. In industrial areas, they are refuges of biological diversity. The long-term ecological research carried out in woodland ponds has allowed us to identify a new site of the occurrence of Placobdella costata (F. Müller) (Hirudinida: Glossiphoniidae) in Poland, the fourth in the southern part of the country. Furthermore, ecological information about the habitat and accompanying freshwater leeches are given.

Publikacja przedstawia wyniki badań florystycznych przeprowadzonych na poboczach dróg powiatowych w granicach gminy Śliwice. Flora przydroży tego regionu liczy 185 gatunków roślin naczyniowych. Współczynnik różnorodności gatunkowej pojedynczych płatów mieści się w granicach 2- 2,5 i jest niewiele mniejszy niż na łąkach. Zgromadzony materiał obejmuje łącznie 186 gatunków roślin naczyniowych - więcej niż na łąkach tego obszaru. Najliczniej występujące gatunki to: Festuca rubra, Arrheriatherum elatius, Elymus repens i Dactylis glomerata. Poza taksonami pospolitymi na przydrożach występuje szereg gatunków objętych ochroną gatunkową. Należą do nich: Frangula alnus, Helichrysum arenarium, Ononis spinosa, Arctosta-phylos uva-ursi, Convallaria majalis oraz Epipactis helleborine, Botrichium lunaria i Botrichium matricariifolium. Wysoka lesistość i ekstensywne rolnictwo w Borach Tucholskich sprzyjają wysokiej wartości przyrodniczej regionu. Przydroża są specyficznymi, odrębnymi siedliskami w leśnym krajobrazie. Z uwagi na bogatą florę, duży zasób rzadkich i chronionych gatunków, jak również dzięki wysokiej bioróżnorodności każdego badanego płatu, przydroża stają się istotnym elementem lokalnej różnorodności gatunkowej.

The paper presents the results of the floristic research carried out on the roadside verges of the county roads within the borders of Śliwice commune. Roadside verges flora of this area consists of 185 species of vascular plants - more than in the neighbouring biocenoses. The species diversity index ranges from 2 to 2.5 - not much lower than in the meadows. Among the most frequent species to be found: Festuca ruhra, Achillea millefolium, Arrhenatherum elatius, Dactylis glomerata, Artemisia vulgaris, Lolium perenne and Elynius repens. Many rare and protected taxa were also present: Frangula alnus, Helichnjsum arenarium, Ononis spinosa, Arclostaphylos uva-ursi, Convallaria majalis, Epipactis helleborine, Botrichium lunaria and Botrichium matricariifolium. Intensive forestation and extensive agriculture in the Tuchola Pinewoods contribute to high conservation value of the region. The roadside verges have become specific and unique habitats in the forest landscape. Due to rich flora, large stock of rare and protected species, in addition to high diversity of each investigated plot, the roadside verges have turned into a significant element of the local biodiversity.
