(3-8) On the Role of the Hypotheses in Zoological Investigations.
Panteleyev P. A. — A large amount of empiric data accumulated in zoology needs
generalization. Generalizations are more productive when there are some hypotheses.
A hypothesis confirmed many times becomes a conception, which elucidates the further
obtaining of knowledge. For example, with the help of two conceptions, the Evolutionary
Role of the Sexes, and the Ecological Bioenergetics, one can see the scientific
achievements obtained on the basis of the hypotheses, the development of which
led to these conceptual ideas.
Key words: evolution, sex, ecological bioenergetics, rodents, variation, origin of species.

(17-22) Life Cycle and Preliminary Stages of Ochyrotylus helvinus
in Middle Asia. Isakov Yu. M. — The preliminary stages of O. helvinus Jakovlev,
1885 are unknown. Collection and observation were made during 1985–1988 in Turkmenistan
and Uzbekistan. Observation of eggs and larvae development were in the nature
and in the laboratory cages. Distribution of the species is reconsidered more
precisely, and its northern margin in Central Asia is determined. Adults hibernate
and start to emerge in April. Oviposition period continues from May up to July.
Young specimens emerge since the middle of July. There are two generations in
a year. Hibernation starts in the middle of August. Each clutch contains 12 eggs
positioned in chess order. Eggs develop 2–4 days. Size of eggs is 0.95 ť 0.65
mm, diameter of cover is 0.42 mm. Calligonum spp. (Polygonaceae), Peganum harmala
(Peganaceae), Salsola australis (Chenopodiaceae), and Stipagrostis pennata (Poaceae)
are the host plants. Preliminary stages of O.helvinus are described.

(23-30) Centuries old dynamics of number of mouse-Similar
rodents in the Black Sea Biosphere Reserve. Selyunina Z. V. — The analysis
of the results of counts of mouse-similar rodents in the reserve shows that periodical
fluctuations in populations numbers of these animals exist. Winter hibernating
species show no evident cyclic dynamics. Depending on this interval 3 cycles exist:
a short-term, a ten-year term, and a 50-year term. The weather dynamics (1936–2001)
also show the 10-year and 50-year term cycles similarly to the mouse-similar mammals.

(31-39) Bats of Tribe Myotini (Mammalia) in the Middle Dnipro
Region: Species Composition, Distribution, and Abundance. Zagorodniuk I. V., Godlevska
O. V. — The tribe is represented in the region by four species. Original data
and collected samples as well as published data verify presence of two Leuconoe
species, namely L. dasycneme, and L. daubentonii. Two other species represented
genus Myotis (M. «mystacinus» and M. nattereri) are recorded by single records
each. Assumptions on the occurrence of two more species of Myotis (M. myotis and
M. bechsteinii) are erroneous. Both Leuconoe species are known to occur in both
winter and autumn-summer time, and they are considered sedentary species. Winter
records of Myotini originate mainly from artificial caves of the steep right bank
of Dnipro River. Total numbers of species records (L. daubentonii, L. dasycneme,
M. nattereri, M. «mystacinus») form a ratio 66 : 14 : 6 : 4, and numbers of their
specimens are 667 : 61 : 29 : 5 respectively.
Key words: bats, fauna, Myotis, Leuconoe, abundance, Ukraine.

(41-50) Current State of the Golden Eagle (Aquila chrysaetso)
Population in the Ukrainian Carpathians. Godovanets B. J. — In Ukraine, the
Golden Eagle (Aquila chrysaetos Linnaeus, 1758) regularly breeds only in the Carpathians.
In that region, the bird is rather poorly studied. A systematic rank of the golden
eagle carpathian breeding population is still undetermined. In 1970–1999, the
species was recorded 109 times in 64 sites in the Ukrainian Carpathians. Most
records are in Chornohora and Svydovets massifs. The Carpathian breeding population
of the golden eagle is about 10–15 pairs. During recent years, a positive tendency
in the Carpathian population is registered. Birds begin to breed in March. Fledglings
leave nest from the mid July to the end of August. The main feed consists of birds,
mammals and carrion. To conserve the golden eagle in the region, a set of measures
should to be implemented as follows: studies of the species, finding and protection
of nests, feeding up birds in winter, attraction with artificial nests, artificial

(51-59) Formation of the altricial type development of birds.
Kovtun M. F., Shatkovska O. V., Shatkovsky Yu. V. — The revision of traditional
hypothesis of origin of the types development birds, using data on the limbs skeletal
and skull embryogenesis of some altricial and precocial birds (Corvus frugilegus,
Riparia riparia, Coturnix japonica, Larus argentatus), was carried out. It was
shown that the appearance and the development (to stage 36) of the skeletal elements
limbs of altricial and precocial birds pass synchronously. This fact refutes the
assertion that development of the skeleton of altricial birds is more intensive
and early. After stage 36 the substitution of the cartilaginous tissue by bone
one is more intensive in the precocial birds. Perhaps that the reorganization
of the embryogenesis of altricial birds lain in change of last stages of embryonic

(67-72) Transmission triggers and pathways in Gyrodactylus
sphinx (Monogenea, Gyrodactylidae). Dmitrieva E. V. — The ratio between the
different ontogenetic stages of gyrodactylids transferred from infected to uninfected
hosts was studied. 72% of transmitted individuals have a functional male reproductive
system and can reproduce only sexually. Therefore, in Gyrodactylus sphinx Dmitrieva
et Gerasev, 2000 transmission mainly involves individuals with a functional male
reproductive system. It is likely that the sexual maturation of gyrodactylids
provides the trigger for migratory behaviour. The restricted occurrence of G.
sphinx on one host species in nature is a result of innate host specificity. Both
the behavioural patterns of G. sphinx and physiological parameters of the fish
uphold the search for a suitable host.
Key words: Gyrodactylidae, Gyrodactylus, transmission, trigger, host specificity.

(77-79) A New Species of the Genus Typhlodromus (Parasitiformes,
Phytoseiidae) from South-Ost Crimea. Kolodochka L. A. — Typhlodromus difficilis
Kolodochka, sp.n. from juniper (Juniperus rufescens Link) is described and figured
(type locality: Crimea, Karadagh State Reserve). A new species is closely related
to Typhlodromus beglarovi Kuznetsov, 1984 and T. laurae Arutunjan, 1974. It differs
from them by the ratio of lengths of setae PV and PM3 (in T. beglarovi setae PV
longer then PM3, in T. laurae these setae almost equal in length as well as in
the new species PM3 shorter then PV), and by relative length of setae PL2 and
PM2 (in T. beglarovi seta PM2 is equal or shorter than PL2, in T. laurae seta
PM2 is shorter than PL2, whereas in the new species seta PM2 is longer then seta
PL2), and by some other minor characters.

(81-84) The State of the Fat Body and the Lifetime of Honey
Bees (Apis mellifera) Invaded by Varroa jacobsoni. Nemkova S. N., Rudenko E. V.
— The fat body cells of the honey bees Apis mellifera Linnaeus, 1758 is shown
to be reduced at the invasion intensity 1–2 (1153.01 ± 139.05 mkm2) and 3–4 mites
Varroa jacobsoni Oudemans, 1904 per bee (952.68 ± 137.72 mkm2) comparing to uninvaded
bees (3030.31 ± 336.87 mkm2), and as the consequence, the lifetime of the bees
invaded by mite decreases. The increasing of extensiveness of the invasion in
bee families raise up to 15.61 ± 1.18% (in September) that leads to 30.4% shortening
of the lifetime of invaded bees on, and 12.5% shortening of uninvaded comparing
to individuals from the colonies with the extensiveness of the mite infestation
1.03 ± 0.31%.

(97-99) Feeding ecology of Curlew Sandpiper, Calidris ferruginea,
during spring stopover in the Sivash Bay (Ukraine). Khomenko S. V. — Curlew
Sandpipers, Calidris ferruginea Pontoppidan, 1763, gathering in the galinic part
of the Sivash are able to efficiently forage on Brine Shrimps (Artemia salina)
using it as a main food. It has been proved, that the birds feed exclusively in
day-time (up to 80% of the observation time). Additional energy income makes on
average 146.3 ± 38.4 kJ/day. At the expense of this, sandpipers increase body
mass at an average rate of 4.3 ± 1.1 g/day. During 5–6 day’s stay at the Sivash
their total body mass increases up to 33–41% compared to the average lean (winter)
body mass. It is the Brine Shrimps, highly abundant and easily available food,
that attracts tens of thousand migratory Curlew Sandpipers to the Sivash.
