Analysis of the Transdanubian region of Hungary according to plant species diversity and floristic geoelement categories

Abstract

The aim of this study was to describe the proportion of floristic geoelements and plant biodiversity in the macroregions of Transdanubia. The core data source used for the analysis was the database of the Hungarian Flora Mapping Programme. The analysed data were summarized in tables and distribution maps. The percentage of continental elements was higher in dry areas, whereas the proportion of circumboreal elements was higher in humid and rainy parts of Transdanubia. According to the climatic zones, the highest value of continental geoelement group occurred in the forest-steppe zone. The plant species diversity and geoelements were analysed also on a lower scale, with Transdanubia specified into five macroregions. The highest diversity values were found in the Transdanubian Mountain and West-Transdanubian regions because of the climatic, topographic, and habitat diversity.

Zooplankton communities in three adjacent softwater lobelia lakes of slightly differentiated morphology and trophic state

Abstract

The paper presents the results of an investigation of physical-chemical features of water as well as rotifer and crustacean abundance and diversity measures, relating to the taxonomic richness and species diversity index, in three lobelia lakes differing in trophic status and morphometric features. The main purpose of this study was to establish the diversity of zooplankton communities in the open water area of lobelia lakes, including extracting species common for each lake and also to find environmental predictors which are responsible for the development of zooplankton communities. Despite the fact that the three studied lakes are of the same origin, located in the same vicinity and have generally similar environmental factors, zooplankton community structure revealed a great variation in reference to species diversity (only ca. 20% of the species were common for all lakes) and particularly in inhabiting species. Obrowo Lake had the most diverse assemblages of both rotifers and crustaceans compared to Modre and Pomysko lakes. In the taxonomic structure species that are rare for the Polish fauna, such as e.g. Holopedium gibberum and Heterocope appendiculata, occurred. Even though the examined lobelia lakes are ecosystems that undergo varying human-induced impacts, they still remain taxonomically very variable aquatic ecosystems, containing rare species of very high ecological status. The observed symptoms of deterioration of water quality, reflected in the zooplankton biocoenotic features, showed that the best conditions were attributed to Obrowo Lake in comparison with the two remaining lakes – Modre and Pomysko. Total nitrogen and chlorophyll a concentration were decisive for the distribution of zooplankton species in Pomysko and Obrowo lakes, while in case of Modre lake water reactivity and conductivity were of higher impact.

Bird Species Diversity of the Mitidja Plain (Northern Algeria) with Emphasis on the Dynamics of Invasive and Expanding Species

Abstract

This treatise investigates the poorly studied bird fauna of Mitidja Plain (Northern Algeria), with particular notes on the occurrence and expansion of new and alien species. Direct observations, supported by ornithological surveys carried out by Progressive Frequential Sampling (PFS), a version of a point count method, have allowed us to identify 125 bird species. These represent 31% of all species known from Algeria. The species recorded belong to 14 orders, 39 families and 37 genera. According to their biogeographic origins, 36 are Mediterranean, 32 Palearctic, 24 Holarctic, 17 European and 16 of European-Turkestani origin. The Mitidja Plain holds 60 resident-breeder species (48% of all registered species) and is a transit zone for many migratory species (summer and winter migrants constituting 20% and 14% of the total, respectively) and occasional visitors (RA = 12%). Among recently expanding species (introduced or local), the Collared Dove Streptopelia decaocto and Wood Pigeon Columba palumbus, sampled by the spot-mapping method, experienced a very rapid population growth. The first observations of the former were made in 1996 in Algiers. Its numbers experienced a steep increase after 2002, starting from 5.75 pairs/10 ha to reach up to 31.5 pairs/10 ha in 2006. The same applies for the Rose-ringed Parakeet Psittacula krameri, surveyed by direct-count at roosting sites. This species has been able to increase and reproduce since its first introduction into the wild in 1996. The increase in study species populations, especially the Rose-ringed Parakeet, may derive from good weather conditions that favoured the species through providing better feeding conditions, thus high reproduction outcomes.
