The Given

Differences in abundance and spatial distribution of small terrestrial mammals were compared between the forest interior and clearing. In total, seven micromammalian species were detected. Of them, only three species were captured within the forest interior, whereas six species were recorded on the clearing. Apodemus flavicollis and Clethrionomys glareolus were dominant species. Another five species were recorded scarcely. Abundance of Apodemus flavicollis reached significantly (P < 0.001) the highest value in the forest interior. On the contrary, Clethrionomys glareolus was significantly (P < 0.001) attracted by the clearing. The distribution of two dominant rodent species probably reflected the high beechnut supply in the given period. The relationships between food supply and microhabitat preferences of Apodemus flavicollis and Clethrionomys glareolus were discussed.

The Impact

Little is known about the impact of small terrestrial mammals on forest regeneration as yet. In order to determine the level of small rodent impact on artificial forest regeneration, 508 saplings have been researched in a spruce monoculture in the Drahany Uplands. With the objective to hone the interpretation of the data, small terrestrial rodents were trapped to help determine species spectrum. The occurrence of Apodemus flavicollis, Clethrionomys glareolus and Sorex araneus was verified. In 52 cases damage to the trunk caused by small rodents was monitored (10.1% of all saplings). 8 specimens (1.6%) had their branches nibbled and 9 saplings (1.8%) had tips of branches or trunk tops browsed. Browsing by Lepus europaeus – 423 (83.3%) of all damaged specimens was significant.

The research has been conducted in 3 biggest cemeteries of Chisinau city: Central (“Armenian”), “Saint Lazarus” (“Doina”) and Jewish. We found 9 species of small mammals (7 species of rodents and 2 shrews). Species of rodents were Clethrionomys glareolus, Microtus rossiaemeridionalis, Apodemus flavicollis, A. sylvaticus, A. uralensis, Rattus norvegicus and Mus musculus and 2 shrew species – Sorex araneus and Crocidura suaveolens. A.sylvaticus was dominant species, followed by M. rossiaemeridionalis and A. flavicollis.

In the years 2006–2011 was studied community of small terrestrial mammals in the Drahanská vrchovina Upland. There were compared four stands of different age and tree species composition (30 years old spruce stand; 105 years old spruce forest; 125 years old mixed stand, and 40 years old beech stand). Totally 276 individuals of small terrestrial mammals were trapped and analyzed. The vast majority of cases were Apodemus flavicollis (163), Clethrionomys glareolus (81 specimen), and Apodemus sylvaticus (28). Besides previous species has been confirmed Sorex araneus (2) and Microtus arvalis (1). At all sites the most numerous species was A. flavicollis. Changes in species abundance were synchronized not only among themselves, but also in comparison to southern Moravia. The smallest amplitude and thus the smallest variation showed a population of mammals in old mixed forest. The highest population densities were found in younger spruce stand. The highest biodiversity according to all aspects except the number of species has been found among spruce stands.

Interesting Species

Communities of small terrestrial mammals were studied in the specific environment of two pheasantries in southern Moravia with different intensity of pheasant management and different diversity of biotopes (RB &minus; intensive pheasantry, HJ &minus; extensive pheasantry). In total, ten species from the order Rodentia and Insectivora were found there in 2002&minus;2005. The rodents <i>Apodemus flavicollis</i>, <i>A. sylvaticus</i> and <i>Clethrionomys glareolus</i> dominated in these habitats. On the other hand, the populations of insectivores were very low, <i>Crocidura leucodon</i> and <i>C. suaveolens</i> being interesting species. RB with the higher variety of biotopes showed significantly higher diversity (<i>P</i> < 0.05) of small mammals (<i>H</i>&prime; = 1.284, ten species determined) than HJ (<i>H</i>&prime; = 1.112, five species determined). The higher intensity of management (the amount of chickens released per unit area and the amount of served food) in RB compared to HJ was not reflected in the relative abundance of the community of small terrestrial mammals (<i>rA</i> in RB = 11.82, in HJ = 11.85) nor in their evenness (<i>E</i>). The probability of difference was <i>P</i> > 0.05. A difference in the diversity of compared communities was conditioned by different diversity of biotopes.

Amphibiotic Insects

The peculiarities of biotope differentiation of amphibiotic insects ecomorphs spectra (Insecta: Ephemeroptera, Plecoptera, Odonata) in hydroecosystems of Ukrainian Carpathians are established. Among Ephemeroptera ecomorphs, the dominant species (in the number of species) were: subclass ploskotili velykoziabrovi zbyrachi-ziskobliuvachi ta khyzhaky; subclass siflonuroidni dribno ziabrovi zbyrachi-ziskobliuvachi. For epirytral, the dominant ecomorphs among the freckles are kryptobionty shchilyn briofily (35%); for metarytral – fitofilni kryptobionty podribniuvachi (61%); litofilni kryptobionty, yaki poliuiut iz zasidky (71%) – predominate in hiporytral. The spatial distribution of ecomorph groups of mayflies and stoneflies in Ukrainian Carpathians is subject to the general tendencies of vertical zonal distribution of trophic groups of zoobenthos, and is consistent with the basic provisions of the theory of river continuum of R. Vannot.

Prevalence and abundance of Cryptosporodium parvum and Giardia spp. were studied in 3 species of rodents from forests and abandoned agricultural fields in N.E. Poland (Clethrionomys glareolus n = 459; Microtus arvalis n = 274; Apodemus flavicollis n = 209). Overall prevalence was consistently higher in the voles compared with A. flavicollis (70·6, 73·0 and 27·8% respectively for C. parvum and 93·9, 96·3 and 48·3% respectively for Giardia spp.). Prevalence and abundance of infection also varied markedly across 3 years with 1998 being a year of higher prevalence and abundance with both species. Fewer older animals (especially C. glareolus and M. arvalis) carried infection with C. parvum and infections in these animals were relatively milder. Although seasonal differences were significant, no consistent pattern of changes was apparent. Host sex did not influence prevalence or abundance of infection with C. parvum, but made a small contribution to a 4-way interaction (in 5-way ANOVA) with other factors in the case of Giardia spp. The 2 species co-occurred significantly and in animals carrying both parasites there was a highly significant positive correlation between abundance of infection with each, even with between-year, seasonal, host age, sex and species differences taken into account. Quantitative associations were confined to the 2 vole species in the study. These results are discussed in relation to the importance of wild rodents as reservoir hosts and sources of infection for local human communities.

Planktonic Communities

The temporal dynamics and spatial distributions of zooplankton in the tidal freshwater portion of the Hudson River were studied over a 3-yr period. We tested the hypothesis that advective transport regulates zooplankton biomass in the Hudson and in lakes, estuaries, and rivers for which we have published values. In the Hudson, zooplankton biomass was negatively correlated with discharge over the entire season (P < 0.0001) as well as during the warmer period of the year (P = 0.007) when biomass was greatest. The spatial distribution of zooplankton over 160-km transects was heterogeneous. Downstream changes in the abundance of a dominant species, Bosmina longirostris, indicate that certain areas of the river support net population growth whereas other areas are population sinks. We infer that zooplankton biomass in the Hudson is a function of the balance between reproduction determined by resources and losses due to advection. Zooplankton biomass differs among lakes, estuaries, and rivers in a manner consistent with the differences in water residence time. Biomass is highest in lakes, lower in saline estuaries and tidal rivers, and lowest in rivers. Advective losses appear to be important in explaining differences between planktonic communities in lentic and lotic environments.
