Small mammal microhabitat use in lowland rain forest of north-east Madagascar

Powiązania:
Acta Theriologica
Opis:
This study describes a systematic small mammal trapping programme in the lowland rain forest of Anandrivola, north-east Madagascar. Trapping in both primary and secondary forest revealed the presence of nine small mammal species. Twenty-six habitat variables measured around each trap site were used to determine microhabitat preferences in the three most common small mammal species.

Dead wood as microhabitat for myxomycetes in selected forest communities in the Polish Carpathian Mts.

Bochynek, Anna
Opis:
The myxomycete biota of two forest complexes in the Polish Carpathian Mts. in the vicinity of Wyrchczadeczka in the Beskid Śląski Mts and the Żłobina Couloir in the Pieniny National Park was investigated. The preservation rate and the species composition of the tree stands differ considerably. A spruce monoculture has developed in the managed forest near Wyrchczadeczka while the Żłobina Couloir is covered by TilioCarpinetum and Dentario glandulosae-Fagetum. Twenty two species were recorded in both areas, seven species only in Wyrchczadeczka and twenty one species only in the Żłobina Couloir. The range of microhabitats favourable for the development of myxomycetes is greater in the multi-species tree stand in the Żłobina Couloir than in the spruce monoculture in Wyrchczadeczka.

Opis:
In arid environments, protist diversity is higher in soil covered by vegetation than in bare soil and is also likely to vary in line with the marked seasonal patterns; however, these patterns have not been explored in detail in arid zones. Herein, we used culture – and morphological-based approaches to describe patterns of amoeboid protist diversity in  vegetated and bare soil areas from the intertropical desert of Tehuacán, Mexico, during dry and wet seasons. Overall, 27 protist species belonging to Amoebozoa, Discoba and Rhizaria were retrieved using culture-dependent methods. Among the soil protist groups found, Discoba (principally represented by Heterolobosea) was always the most prevalent taxa. Protist diversity was different between soil with vegetation and bare soil, principally during the dry season. Moreover, the electrical conductivity and pH of the soil were correlated with the protist species during the wet season. Our results support the hypothesis that soil protist diversity patterns exhibit a seasonal variation between dry  and wet seasons. This seasonal variation likely relies on water availability, although the role of other environmental factors cannot be completely ruled out. In addition, the soils with vegetation could be a refuge for the amoeboid protists during the harsh soil conditions of dry seasons.

Opis:
Floristic studies were carried out in eight botanical gardens in Poland in the years 1992-1999. It was demonstrated that the spontaneous synanthropic flora of the gardens consisted of 1092 taxa in the rank of a genus or lower, among which alien species constituted 55% of the flora studied. Ergasiophygophytes, of which the introduction is closely associated with the activities of the botanical gardens, dominated in the latter group of species. It appeared that the flora of the studied botanical gardens was rather similar. However, the structure of the flora of different spatial units (six types of microhabitats) distinguished in the particular gardens varied, which was associated with the various management practices. The flora of microhabitats identified in the gardens differed with respect to the number of taxa and spectra of geographical-historical groups of species and life forms. Ruderal sites, arable lands and roadsides supported the highest number of taxa (the flora of the above spatial units was represented by 646, 645 and 597 taxa, respectively). Moreover, they were characterized by a high proportion of annual plants in the flora (43, 38 and 34%, respectively) and by a relatively small representation of apophytes (39% in all the three types of microhabitats). The flora of wet areas and parks was, however, poor in species (154 and 403 species, respectively), but relatively rich in apophytes (72 and 55% of the flora, respectively) and with a low contribution of therophytes (19 and 20%, respectively). The present data were compared with the findings of other authors who investigated the synanthropic flora of cities in which the botanical gardens were located. The comparative analysis of the flora of Poznań and Łódź showed a great richness of species (in relation to size of the area studied) and a high incidence of aliens (especially those, which had not become established permanently) in the botanical gardens. However comparative studies of the flora of Warsaw and that of the two botanical gardens established in the city revealed that the proportion of alien species was lower in case of these gardens. In Warsaw the flora of areas, which had been managed in the same way as those of the botanical gardens, was also investigated. It was found that the botanical gardens in Warsaw were more similar to cemeteries with respect to the structure of flora than they were to the allotments. The present study showed that the high variability of flora within the particular gardens is attributed to the different ways the area is utilized.

Populations of Phyllitis scolopendrium (L.) Newm. display a clumped spatial structure. The distribution pattern mainly depends on the mosaic of gruss. There is a significant negative relationship between the occurrence or hart's tongue clusters and light intensity. Tree stand clearing do not limit the development of the population. A decisive role in shading of hart's tongue is played by the rich forest floor vegetation which retains 43.3-71.8% of light penetrating through tree crowns. In the population from the Gorce Mts. the density of individuals is positively correlated with their size. Analysis of the size structure of individuals indicates that the leaves of the juveniles do not exceed a 6-cm length and that the juveniles form no more than 8 leaves.

Opis:
The microhabitat selection of two hand-reared polecats, Mustela putorius Linnaeus, 1758, was investigated in an experimental outdoor enclosure. The animals showed a finely-scaled preference for densley structured microhabitats even within a habitat offering cover (oak forest). Experimental modifications of the vegetation cover resulted in significant changes of microhabitat use.

Opis:
In the years 1997-1999, studies on the intensity of the slug Arion lusitanicus occurring in different microhabitats were carried out on the territory of Podkarpackie province. Observations were performed in the environments of vegetable gardens, arable fields and non-crop areas. The intensity of the slug occurrence varied greatly in arable crops of different plant species and in other microhabitats. Vegetable crops and areas adjacent to them were inhabited by the slug most numerously. Considerably less slugs occurred in agricultural plant crops.
W latach 1997-1999 na terenie województwa podkarpackiego przeprowadzono badania nad nasileniem występowania ślimaka Arion lusitanicus w różnych mikrosiedliskach. Obserwacje wykonano w środowiskach ogrodów, pól uprawnych oraz na terenach nieuprawnych. W miejscach licznej obecności ślimaka (uprawy roślin, parki, cmentarze, brzegi rzek, nieużytki, śmietniska) obserwowano jego zagęszczenia w przeliczeniu na m² powierzchni. Nasilenie występowania ślimaka było silnie zróżnicowane w uprawach różnych gatunków roślin oraz w innych mikrosiedliskach. Najliczniej zasiedlane przez ślimaka były uprawy warzyw i tereny do nich przyległe. Licznie zasiedlane były także uprawy kwiatów oraz bylin, łąki i zachwaszczone pola. Natomiast znacznie mniej ślimaków stwierdzono w uprawach roślin rolniczych.
