(Mollusca: Gastropoda
terrestria) of the Telašćica Nature Park (Dugi otok, Croatia). Vol. 13, No. 2., 95-113, 2004,
Zagreb.
In field research into the Telašćica Nature Park (Dugi otok, Croatia), 38 species of terrestrial
snails were determined. Of these, only 14
taxa had been recorded in the literature. Among the
species, particularly
prominent were the narrowly endemic Delima edmibrani (Štamol & Slapnik,
2002) the range of which is restricted exclusively to
the borders of the Park,
the endemic Agathylla lamellosa (Schubert et Wagner, 1829), which has
so far been
known from South Dalmatia and Montenegro, Testacella
scutulum G.
B. Sowerby I, 1820, for which
Telašćica is the second and at the same time the most
southerly site in Croatia, the endemic Chondrina
spelta ventilatoris
(Westerlund, 1875), for which this is the westernmost finding
site, and Paralaoma
servilis (Schuttleworth,
1852),
for which this is the sixth site recorded in Croatia. Because of the
many
visitors whose movements represent a potential threat to the habitats
of
endemic species, it is proposed that this area be protected.

(Gastropoda, Pulmonata, Ellobiidae) of the karst region in Croatia. Records
of the various taxa are listed and a UTM distributional map of Croatia

Terrestrial isopods
(Isopoda: Oniscidea) of Baranya (Croatia). Vol. 13, No. 2., 161-170, 2004, Zagreb.
Pitfall samples were taken during
summer 2003 in 25 habitats of the Baranya triangle (Croatia) to describe the isopod
fauna. The
125 traps caught a total of 2,808 isopods belonging to 11 species: Haplophthalmus danicus, Hyloniscus riparius,
Platyarthrus hoffmannseggii, Cylisticus
convexus, Porcellium collicola, Protracheoniscus
politus, Trachelipus ratzeburgii, Trachelipus
nodulosus, Trachelipus rathkii, Armadillidium
vulgare and Armadillidium zenckeri. The most
characteristic species of the area are A.
vulgare, T. rathkii, P. collicola and H.
riparius. The composition of the isopod assemblage proved to be
similar to
that in the Hungarian part of the Drava lowland.

magnatum growth in Motovun Forest, Istria. Nat.
Croat., Vol. 13,
No. 2, 171-185, 2004, Zagreb.
The
mixed oak forest
located near the town of Motovun is a
well-known white truffle (Tuber magnatum Pico) producing area of the Istria
region. Motovun Forest covers a 900-ha
area in the fluvial plain of the Mirna River, which flows into the
Adriatic Sea
through a hilly landscape originating in a sedimentary sequence of a
Triassic-Eocene carbonatic platform and Eocene-Oligocene Flysch
turbidites. T. magnatum production has been
decreasing in the last 10 years and a study was specifically performed
in an
attempt to explain this. Productive soils of the valley bottom were
compared
with unproductive soils on the slopes, the latter being drier, thinner
and more developed than
the former. T. magnatum carpophores
are not found all over the fluvial plain and Motovun Forest was
further
subdivided into productive, unproductive and occasionally productive
areas. All
soils of the valley bottom
were thick and continuously rejuvenated by the frequent arrival of fine
sediments from slopes, but only unproductive ones were characterized by
water
saturation in some periods of the year. The soil comparison proved the
need of T.
magnatum for an alkaline, moist, very well drained and aerated soil
environment. Moreover, soils suitable for T. magnatum should be
neither
too dry nor too moist. In Motovun Forest, the
decrease in production has been
taking place in conjunction with public works that have modified the
hydraulic
equilibrium of the area causing an overall drying of the forest soil.

E.: The determination and taxonomic problems of palaeogene
fossil macroflora from Slovenia and Croatia. Nat.
Croat., Vol. 13, No. 2., 187-196,
2004, Zagreb.
This paper discusses
the complexity of the
determination and taxonomy of Palaeogene fossil floras from Slovenia (village of
Socka, north of Celje; Sava folds in Central
Slovenia) and Croatia (Central
Dalmatia - Mt
Promina). One of the most
important problems presented by the determination of individual species
of
fossil leaves is connected with the complex classification (species,
genus and
family) of traditional determinations of architecture and leaf
morphology and
also of cuticular studies. In this case, the problems are related to
the
determination of some fossil leaves and the morphological similarities
inside
some families, genera or species and among some families. This is
related to conifers
(Cupressaceae, Taxodiaceae, Araucariaceae), laurels (similarities among
themselves and between some families), the families Myricaceae,
Moraceae,
Rhamnaceae, Proteaceae, Sapotaceae and “Leguminosae” type of leaves. In
spite
of these problems general palaeobotanical conclusions are very close to
composition of classic Palaeogene palaeo-phytoassociations.

molly males (Poecilia mexicana) do
not recognise receptive females without body contact. Nat. Croat., Vol.
13, No.
2., 197-200, 2004, Zagreb.
We investigated the preference of
Cave molly males to associate with a receptive or a non-receptive
female while
body contact was prevented but water-borne cues were allowed to reach
the male.
Both in light and in darkness, males did not prefer the receptive
female. Water-borne chemical cues (pheromones) seem to be absent or
they are not
detected/used by males, respectively.
