Abstract
The first arrival dates during the spring migration and the timing of breeding of starlings were recorded for the years 1980–2003 in the village of Mokrice (46°00'N, 15°55'E) in NW Croatia. The correlation between first arrival date and timing of breeding was not statistically significant.

Abstract
The altitudinal distribution of bats of four Plecotus species in Croatia was analysed. P. austriacus and P. kolombatovici are restricted to lower altitudes, under 800 m a.s.l.. P. auritus inhabits continental forest habitats, preferably beech forests, with the exception of Pannonian lowland riparian forests of common oak which also lie under 100 m a.s.l.. As distinct from the other three Plecotus species, Croatian specimens of P. macrobullaris have an extremely wide altitudinal distribution, ranging from sea level to mountain tops, but with most localities under 800 m a.s.l.

Abstract
Algal occurrence, with particular emphasis on diatoms, was investigated over a two-year period on the travertine barriers of the Krka River in Slovenia. The purpose of the investigation was to establish qualitative composition and the relative abundance of the periphyton. In 1999 and 2000, basic physical and chemical parameters were measured. Altogether, 81 algal taxa were determined. Most of them belonged to Bacillariophyceae. Fifteen species and subspecies were new to Slovenia, 14 of them belonging to Bacillariophyceae and one to Cyanobacteria. Most of the new species and subspecies belonged to genera Nitzschia (5) and Navicula (4).

Abstract
A review of the development of the vegetation in the inland area of Croatia includes the period of the Postglacial, and is based on a synthesis of previous archaeobotanical research, including pollen analysis, and analysis of plant macro-fossils. Changes in vegetation through individual postglacial periods are shown, particular attention being devoted to anthropogenic impacts on the vegetation.

Abstract
The relationship between morphometric measurements (15) and meristic characters (8) were examined in 237 specimens of Mediterranean horse mackerel (105 females, 101 males and 31 immature specimens) caught in the central Adriatic Sea. The goal of this paper was to investigate: whether there are morphological differences between males and females; the existence of homogenous or heterogeneous morphology stock; changes in morphometric characters with an increase in body length. Morphological differences between males and females were not marked. Modal values specific for Trachurus species morphologic characters, such as number of lateral line scales, maximum height of scales in anterior and posterior part of lateral line, point at which dorsal accessory lateral line is terminated and values of other biometric properties indicated a possible homogeneous morphology stock of T. mediterraneus in the central Adriatic Sea. Changes in some morphometric characters obtained in conjunction with an increase in body length showed that smaller specimens have longer head, anal and ventral fin than adult specimens. On the other hand, with an increase in total length, the fish have larger preorbital and postorbital distance, smaller eye and maximum height of scales in the lateral line than smaller fishes. The negative correlation recorded for the maximum and minimum body depth indicates that the body becomes progressively elongated.

Abstract
During the summers from 1995–2000 the benthos was studied at 63 sites by scuba- and skin-divers. Polyplacophora molluscs were recorded at 36 sites. Ten species were identified, i.e. 63 % of the Adriatic Sea chitons, and 34 % of taxa recorded in the Mediterranean. Synonyms, habitat, depth range and general distribution are noted for each species. With the aim of updating the distributional pattern of chitons in the Adriatic Sea, the authors’ unpublished records of a number of species have been appended.

Abstract
Croatodirus casalei Giachino & Jal`i}, new species from N Velebit, Lubenovac, Slova~ka jama pothole, and C. ozimeci Casale, Giachino & Jal`i} new species, from Lokve, Lokvarka {pilja cave, are described. The morphological features of the new taxa are compared with those of the type species of the genus (C. bozicevici Casale, Giachino & Jal`i}, 2000). The genus is confirmed as a homogeneous, well characterized and monophyletic unit, and is attributed to the phyletic lineage of Anthroherpon. Velebitodromus, new genus, smidai new species, is described from N Velebit, Lubenovac, Mali kuk, Slova~ka jama pothole. Owing to both external features and structures of male and female genitalia, the genus is attributed to the phyletic lineage of Anthroherpon, and is recognized as related to the genera Anthroherpon Reitter, 1889, and Paranthrophilon Reitter, 1889.
