Протягом 30-ї польської та 10-ї української експедицій, з 09,11,2005 по 09,02,2006 р., закладено дев’ять стаціонарних ділянок, які охоплювали практично весь спектр умов вільної від льоду території біля польської антарктичної станції Г.

За особливостями трав’яних угруповань, які залежать від екологічних умов у градієнті відстані від краю льодовика, виділено три окремі колонізаційні зони. Ймовірно, зона I (прибережні локалітети) є вихідною колонізаційною зоною далена від льодовика й океану, — оптимальна для існування судинних рослин на сучасному етапі тарктичної трав’яної тундрової формації на нові території.
Изучена зависимость распространения антарктической тундры в градиенте экологических условий, сформировавшихся в процессе отступления ледников. Во время 30-й польской и 10-й украинской экспедиций, с 09.11.2005 по 09.02.2006, заложено девять стационарных площадок, которые охватывали практически весь спектр условий свободной ото льда территории в окрестностях польской антарктической станции Г. Арцтовского на острове Короля Георга (Южные Шотландские о-ва). Основываясь на особенностях травяных сообществ, зависящих от экологических условий в градиенте расстояния от края ледника, выделено три колонизационные зоны. Вероятно, зона I (прибрежные локалитеты) — исходная зона колонизации; зона II, равноотдаленная от ледника и океана, оптимальна для сосудистых растений на современном этапе; зона III, расположенная в непосредственной близости от края отступающего ледника, отражает экспансию антарктической травяной тундровой формации на новые территории.

ANTARCTIC HERB TUNDRA
COLONIZATION ZONES IN THE
CONTEXT OF ECOLOGICAL GRADIENT
OF GLACIAL RETREAT
K e y w o r d s: Antarctic herb tundra formation, colonization
zones, King George Island
Inroduction
Only 2 species of vascular plants can be found in the native recent flora of the
Maritime Antarctic: Deschamps³a antarct³ca Desv. (Poaceae) and Colobanthus
qu³tens³s (Kunth) Bartl. (Caryophyllaceae) [9]. Both species form the following
associations of Antarctic herb tundra formation: Deschamps³a antarct³ca-Colobanthus
qu³tens³s, Deschamps³a antarct³ca and Deschamps³a antarct³ca-Polytr³chum p³l³ferum
[11, 13, 14]. Mosses (Bryophyta) are a significant part of the latter association. Usually
lichens are not included in Antarctic herb tundra formation, they are considered to
form separate associations [11, 13]. Island glaciers continue to melt and new territories
are released from ice in the consequence of warming in Maritime Antarctic [12].
Glacier expansions, which alternated by warming periods, are known to have occurred
in Antarctic since Pliocene [7]. Glacial areas altered periodically during Quaternary
climate fluctuations [20] reducing or expanding areas available for vegetation. Present
retreat of the Ecology glacier in the environs of the H. Arctowski Polish Antarctic
Station (King George Island, South Shetland Archipelago) forms an environmental
gradient from the edge of the glacier to the ocean coast. Thus, studying the
peculiarities of Antarctic herb tundra formation in this gradient became the goal of
the current investigation. We tried to elucidate vegetation colonization zones in the
direction from the ocean coast to the edge of the glacier.
Methods
Study area
During the 30-th Polish and the 10-th Ukrainian expeditions (09.11.2005—
09.02.2006) nine stationary study plots (Fig. 1) were established near the Polish
Antarctic H. Arctowski Station at the King George Island of South Shetland Islands.
The coordinates of the plots were determined using portative GPS.

As a criterion to select a plot we used presence of at least one species of vascular
plants that determine the Antarctic herb tundra formation. The plots were established
at different distances between the glacier and coastal zone in order to cover the
whole gradient of environmental conditions on the ice-free area. The survey did
not cover the bottom of the central hollow (so-called Krokiew, Fig. 1), which was
not accessible during the investigation.
All plots are briefly described in Table 1.
Study approach
The size of the plots varied from 9 m2 (1, 4, 5, 8, 9) to 4 m2 (2, 3) to 1 m2 (6, 7)
due to the relief specifics. Phytocenological relevees were made for each site and its
environs. Species diversity for Bryophyta (mosses and liverworts) and macrophyte
alga was also studied. The samples of mosses and liverworts were identified using
standard methods and specific identification keys [2, 15, 17]. Individual cover was
noted for every species of vascular plants at the plots. The age structures of both
vascular plants’ populations were determined according to the scheme shown in
Figures 2, 3.
An satellite photo of the area of the Arctowski Station and a topographic map
at a scale of 1:12.500 by R. Pudelko [16] were used for the analysis of relief,

Results and Discussion
The area near Arctowski Station is
unique in comparison with other
ice-free territories on King George
Island. First of all the originality of
this area is determined by relief:
mountain ridges form a peculiar
enclosed «quadrangle» (Krokiew,
Fig. 1); depressions join the ridges (Italia Valley and coastal depressions near the
station). Meltwater flow is isolated from the «quadrangle» by its south-eastern walls
(Fig. 4).
Water balance on the majority of ice-free territory near Arctowski Station is
formed by thawing permafrost and snow that accumulates in the «quadrangle». Melt
waters from the «quadrangle» form six creek watersheds [18]. The water flows along
the walls of mountain ridges framing the «quadrangle» to the coast. A lot of moisture
is accumulated at the bottom of the «quadrangle», thus establishing favourable
conditions for the existence of Antarctic herb tundra formation. Notably, coastal
localities of Antarctic herb tundra are additionally moistened by the ocean air [18].
At present time there is distinct evidence of expansion of the tundra into the
areas adjacent to the glacier (Fig. 1; the 9th plot is located on the territory where
the glacier was noted in 1979 [16]).
According to the environmental gradient from the edge of the glacier to the
ocean coast, we divided the research sites into three localities. We supposed that
their localization demonstrates subsequent stages of postglacial colonization. These
localities were conventionally named as colonization zones. The first zone (I)
included plots 1—5 (coastal localities), the second one (II) — plots 6—8, which are
equally remote from the coastal line and glacier. Only the plot 9 belongs to the
third zone (III) near Ecology Glacier where the environment is quite homogenous.
Only the site 9 belongs to the third zone (III) near Ecology Glacier where the
environment is quite homogenous.
Notably, vascular plants as well as Bryophyta were found in all three colonization
zones. All three taxa along with lichens seem to be primary colonizers in all studied
sites. Also, C. qu³tens³s was scarce in comparison with D. antarct³ca in all zones,
probably because its reproductive success and rate of ramification were lower
regardless of the growth zone.
Zone I is characterized by considerable moistening and swamping. Total
vegetation cover varied from 56 to 98 %; green alga Pras³ola cr³spa (L³ghtf.) Menegh

was present. This zone was the first one to become free from the glacier and is
relatively stable. The glacier only slightly affects this zone, as it is separated from it
by high mountain ridges. As a result of warm current running along the western
coast of Antarctic Peninsula this zone could have remained free from the glacier
even during the period of maximal Pleistocene glaciation. Perhaps, gradual expansion
of the formation to the nearby territories during continuous glacial retreat occurred
from this very area.
Coastal localities of Deschamps³a antarct³ca — Polytr³chum p³l³ferum association,
found at the Fildes Peninsula [8], hardly depend on glacial water because of the
considerable distance from the edge of glacial sheet. We assume that they are similar
to zone I on the area around Arctowski Station.
Zone II is characterized by moderate moistening, as melt water is drained into
streams, flowing to the ocean along the hollows. Total vegetation cover was 100 %
in all sites here. About a half of it formed by Bryophyta; D. antarct³ca considerably
prevailed over C. qu³tens³s (5:1, respectively).
Zone III is situated outside the coastal area at the edge of the glacier and is a
rocky postglacial moraine, 5—10 m a.s.l. Total vegetation cover here was about 56 %
(50 % for mosses, 3 % for D. antarct³ca and 3 % for C. qu³tens³s).

Thus, colonization zones can be identified on the basis of certain parameters.
The first one is combined vegetation cover of both species of vascular plants. At the
same time, individual cover of D. antarct³ca and C. qu³tens³s cannot be used to identify
a colonization zone (see Table 2).
Another parameter is reflected by the variety of higher plants. Thus, the maximal
diversity of mosses and presence of liverworts was observed in zone II, as compared
with the other two ones (Table 3).
One can thus suppose that at the present time Zone II is the most favourable
for the Deschamps³a antarct³ca — Polytr³chum p³l³ferum association of Antarctic herb
tundra formation, probably due to optimal combination of humidity and insolation.

Noteworthy, all plots greatly differed in steepness and exposition of slopes and the
distribution of the tundra formation, which corresponds with data in the literature [13].

To find the most optimal zone for these species’ existence in the environs of
H. Arctowski Station we analysed population parameters of D. antarct³ca and
C. qu³tens³s in all plots. The analysis of age structure shows that adult (G2) and old
(G3) generative plants dominated in D. antarct³ca population of zone I. In zones II
and III there were much more pregenerative (J, Im and V stages) plants (Fig. 2);
here dominates the invasion strategy. It reflects the invasive nature of D. antarctica
of both zones and its potential ability to occupy new areas and reproduce. This was
not so for C. qu³tens³s.
It should be noted here, that accidental nitrification, which obviously effects
the individual cover of D. antarct³ca and C. qu³tens³s and the diversity of other plants,
considerably hampers all efforts to identify colonization zones and to search for
optimum ones. Mosaic supplies of organic substances by birds and sea mammals
produce heterogeneity even within a single hypothetic colonization zone. Moreover,
it forms an additional ecological gradient that is described in detail in [19]. We think
that variability of population status of C. qu³tens³s is caused mainly by heterogeneity
of organic supply. Another indicator of the heterogeneity is the expansion of green
alga Pras³ola cr³spa, which is known to be a marker for high nitrification [19]. The
presence of both nitrophilous species is of intrazonal nature.
Conclusions
1. Distinct colonization zones were revealed as a result of heterogeneity analysis of
vascular plants formation in ecological gradient from the edge of the glacier to the
ocean.
2. Three colonization zones can be distinguished in the study area. Possibly,
zone I is the initial one, and zone II, which is equally distanced from the ocean
and glacier, is optimal for higher plants at the present time.
3. Zone III, which is the closest to the glacier, reflects the expansion of Antarctic
herb tundra formation to new areas released from the glacier.

Inozemtseva, O.V. Tyschenko, O. Mustafa, I.A. Kozeretska // Укр. ботан. журн. — 2008. — Т. 65, № 4. — С. 504-512. — Бібліогр.: 20 назв. — англ. 0372-4123 https://nasplib.isofts.kiev.ua/handle/123456789/9835 Досліджено залежність поширення антарктичної тундри в градієнті екологічних умов, який сформувався у процесі відступу льодовиків. Протягом 30-ї польської та 10-ї української експедицій, з 09,11,2005 по 09,02,2006 р., закладено дев’ять стаціонарних ділянок, які охоплювали практично весь спектр умов вільної від льоду території біля польської антарктичної станції Г. Арцтовського на острові Короля Георга (Південні Шотландські о-ви). За особливостями трав’яних угруповань, які залежать від екологічних умов у градієнті відстані від краю льодовика, виділено три окремі колонізаційні зони. Ймовірно, зона I (прибережні локалітети) є вихідною колонізаційною зоною далена від льодовика й океану, — оптимальна для існування судинних рослин на сучасному етапі тарктичної трав’яної тундрової формації на нові території. Изучена зависимость распространения антарктической тундры в градиенте экологических условий, сформировавшихся в процессе отступления ледников. Во время 30-й польской и 10-й украинской экспедиций, с 09.11.2005 по 09.02.2006, заложено девять стационарных площадок, которые охватывали практически весь спектр условий свободной ото льда территории в окрестностях польской антарктической станции Г. Арцтовского на острове Короля Георга (Южные Шотландские о-ва). Основываясь на особенностях травяных сообществ, зависящих от экологических условий в градиенте расстояния от края ледника, выделено три колонизационные зоны. Вероятно, зона I (прибрежные локалитеты) — исходная зона колонизации; зона II, равноотдаленная от ледника и океана, оптимальна для сосудистых растений на современном этапе; зона III, расположенная в непосредственной близости от края отступающего ледника, отражает экспансию антарктической травяной тундровой формации на новые территории. en Інститут ботаніки ім.
