Distribution And Ecology

In the framework of a long-term project launched by the Stelvio National Park for monitoring the spatio-temporal patterns in plant, arthropod and vertebrate species assemblages, the results on the sampled cholevid species are reported. The abundance of specimens and the distribution of species has been studied in relation to nine environmental variables. Five species of the tribe Cholevini were sampled during this research: Apocatops nigrita, Catops coracinus, Catops fuliginosu, Catops nigricans and Catops tristis. The most abundant and frequent species were Apocatops nigrita and Catops coracinus. The effect of the environmental variables on the distribution of two of the most abundant species (C. coracinus, A. nigrita) was tested and described. Updated information about the distribution and ecology of the five sampled species were provided.

Different Seasons

Cyclic fluctations in the popu]ation density of rnicrotine rodents have been known since antiquity. However, factors responsible for this phenomenon are not known. The objectives of this long term study are essentially threefold: 1. characterize those environmental variables that might affect Microtus montanus in different seasons of the year; 2. record the growth, maturation and reproductive activity of the voles under natural conditions; and 3. determine the maturational, as well as, the seasonal pelage changes of these rodents. The data resulting from the execution of the above objectives would be correlated in an attempt to determine the causes undedying the multiannual fluctuations in the population density of these microtine rodents in Grand Teton National Park.

Fish assemblages were sampled at nine sites in the lower Vaal River in the Vaalbos National Park and adjacent properties. A total of 1543 fish from 10 species was recorded. Ordination revealed spatial variation in assemblage structure, with the distinction primarily between communities in rapids and deep pools. Flow velocity, depth and percentage cover were important determinants offish assemblage structure. The length frequency distribution of abundant species indicated successful recruitment. Several differences in the species compliment compared to earlier studies were evident, including high abundance of Barbus paludinosus and Austro^lanis sclateri, and the absence of Barbus anoplus. The length-mass relationships of large cyprmids indicated long-term declines in the physical condition of fish.

Little is known about the distribution and ecology of the cryptic and unique marsupial mole. In this paper we report on the habitat preferences and surfacing behaviour of marsupial moles on the basis of surface sign surveys conducted in Uluru-Kata Tjuta National Park and Ayers Rock Resort over a 12-month period by Uluru-Kata Tjuta National Park staff and traditional owners. A key aim of the study was to assess the potential viability of using surface sign as a rapid, non-intrusive alternative to traditional survey methods. We found that surfacing occurred widely across the study area, but that it was highly variable both across survey sites and over time. Significant relationships existed between surface sign counts and environmental variables, including fire age, timing of significant rainfall events, presence of infrastructure and the cumulative rainfall received in the preceding three months. We concluded that the use of marsupial mole surface sign is likely to be a useful method for monitoring the distribution, abundance and habitat requirements of this cryptic species.

Rodent Populations

Fluctuations in the composition and abundance of a small-mammal assemblage were studied in a hummock grassland dominated by Plectrachne schinzii at Watarrka National Park from 1988 to 1993. During this period an experiment was conducted to examine the short-term effects of fire on the rodents. We caught three species of rodent (Pseudomys hermannsburgensis, Notomys alexis and Mus domesticus). All species reached their greatest density in spring 1989 during an exceptionally wet period that extended from mid- 1988 to 1990. P. hermannsburgensis was the most abundant species and showed a 10-fold fluctuation in numbers over the sample period; N. alexis was the next most abundant species and showed a 5-fold increase but the population took longer to decline. M. domesticus was recorded only during the period of high rainfall. The number of M. domesticus was significantly less on the burnt plots than on the unburnt plots. Neither P. hermannsburgensis nor N. alexis showed significant differences between burnt and unburnt plots. This study illustrates the impact of rainfall events on the composition and density of small-mammal populations in spinifex grasslands in central Australia. Our results lead to the prediction that rodent populations will achieve densities in the order of 10 individuals ha-' or more in regions that experience three consecutive 6-month periods each with rainfall at 150% of the long-term average. This sequence apparently needs to follow a dry period where rainfall is no more than 85% of the long-term annual average for two consecutive 12-month periods.

Water Spread

Knowledge of changes in wetlands is becoming a very important issue for sustainable management of natural resources. The present work has been carried out: in Keoladeo Ghana National Park (KNP), a RAMSAR site to study the dynamics of wetlands with reference to long-term and seasonal changes in extent of water spread, vegetation types and to build a spatial database on wetlands. Multi-temporal satellite data of Landsat MSS (1977), Landsat TM data (1989), IRS P6 AWIFS (2005) and IRS P6 LISS III data (2005-2006) was used for mapping and spatial analysis. Comparisons between 1977 and 2005 indicated that changes in overall wetland areas were significant. The total area of wetland in March 1977 was 186 hectares and in March 2005 it was found to be 7.5 ha. There is a drastic reduction in spatial extent of water spread from October to May and results indicated that the total area ranged from 528 ha (October 2005) to 7.5 ha (March-May 2005). The study clearly points that Geoinformatics have become very effective tool for wetlands mapping and monitoring.

Gran Paradiso National Park

The last Capricorns (Capra ibex ibex) in the Alps survived during the nineteenth century in the Aosta valley thanks to the royal hunting reservation (today Gran Paradiso national park). Capricorns from this reservation were successfully re-introduced in Switzerland after its Capricorn population had disappeared. Currently in Switzerland there are 13200 Capricorns. Every year 1000 are hunted in order to prevent a large variation and overaging of their population and the damage of pasture. In contrast, in the Gran Paradiso national park the game population regulates itself naturally for over eighty years. There are large fluctuations in the Capricorn population (2600–5000) which are most likely due to the climate, amount of snow, population density and to the interactions of these factors. The long-term surveys in the Gran Paradiso national park and the investigations of the capacity of this area are a valuable example for the optimal management of the ibexes in Switzerland.
