  Охарактеризовано видовий склад, проективне вкриття, трапляння, рясність та запаси трав’яного вкриття на землях, які вийшли із сільськогосподарського користування в умовах Західного Полісся України. Для можливого створення вольєри та утримання оленя лісового виділено п’ять біотопів: свіжі суходільні луки, вологі луки, сирі луки, зарості верби з очеретом, сільськогосподарські землі (рілля). Наведено характеристику відносного поїдання виявлених видів трав’яних рослин оленем. У межах колишніх сільськогосподарських земель обліковано 71 вид судинних рослин. Найбільшу кількість видів трав відзначено на пробних площах суходільного та вологого лугу, відповідно, 27 і 25 видів. В умовах суходолу за проективним вкриттям переважають п’ять видів рослин, загальне проективне вкриття яких становить 53%. Домінуючими травами вологих лук є Solidago canadensis L., Juncus conglomeratus L., Calamagrostis epigeios (L.) Roth, Deschampsia caespitosa (L.), Phalaroides arundinacea (L.) Rausch. Загальне проективне вкриття панівних трав становить 71%. У верболозах, де ростуть ламка, козяча та сіра верби, а також зрідка трапляється слива, зареєстровано найменше видове різноманіття трав. Тут переважає Phragmites vulgaris Samp., трапляння якого досягає 80%, а проективне вкриття  – 60%. Рясність трав’яного вкриття у межах лучної ділянки поступово зменшується від 87% у верболозах до 76% в умовах вологого та 65% – суходільного лугу. У приболотній смузі видова насиченість літньо-осінніх трав становить лише 10 видів з домінуванням гідрофільної рослини Phalaroides arundinacea (L.). В умовах сирого сугруду (болото) та вологого субору (вологі луки) зареєстровано найбільшу масу трав’яних рослин, відповідно 2,5 кг/м2  та 1,3 кг/м2. Найменша маса трав є характерною для свіжого лугу та верболозів із заростями очерету: 0,45 та 1,09 кг/м2. Більшість видів трав’яних рослин, що ростуть у різних досліджуваних лучних біотопах Західного Полісся, поїдають олені і можуть бути використані для забезпечення їхніх кормових потреб у вольєрному розведенні.

Abstract Weeds competing with seedlings of trees for nutrients, moisture, light and space, drown out their growth in nurseries and forest crops. Currently, in forestry, weed control is mainly carried out in forest nurseries, less often during the preparation of the area intended for afforestation, but sporadically in forest crops. The most important species of weeds threatening seedlings of forest trees include Senecio vulgaris, S. silvaticus, Deschampsia caespitosa, Pteridium aquilinum, Agropyron repens, Calamagrostis epigeios and Equisetum arvense. In Poland, herbicides have the largest share (about 50%) in the sale of plant protection products, but the scale of their use in forests is small, compared to agriculture. In 2012, 915 herbicides were registered in the country, out of which only 14 products (0.5%) were for use in forestry. In the years 1999–2019, 31 herbicides were registered for the protection of forest nurseries and crops, which included 13 active substances belonging to 11 chemical groups, of which 9 active substances have been used up to now. Most herbicides (15–16) were used in the years 2004–2006, the lowest in 1999–2000 and in 2014 (4 products). The most popular active substance has been glyphosate contained in 18 products.

Taxonomic Relationships

During the nineteenth century, scientific literature and official reports recorded the occurrence of a population of red deer, Cervus elaphus, on the island of Lampedusa (Pelagian Archipelago, Italy). Osteological specimens collected by the zoologist Enrico Hillier Giglioli towards the end of the century confirmed these references. Since cervids are not found among the fossil fauna of the island, the red deer must have been introduced by man although we do not yet know precisely when. The former existence of the species on Lampedusa is discussed by comparison of literary material and bone evidence. The population's probable origins and its taxonomic relationships with other Mediterranean red deer populations are also analysed.

The role of interferon in early pregnancy in red deer was investigated by (a) measuring production of interferon by the conceptus, (b) testing the anti-luteolytic effect of recombinant interferon-tau in non-pregnant hinds, and (c) treatment of hinds with interferon after asynchronous embryo transfer. Blastocysts were collected from 34 hinds by uterine flushing 14 (n = 2), 16 (n = 2), 18 (n = 8), 20 (n = 13) or 22 (n = 9) days after synchronization of oestrus with progesterone withdrawal. Interferon anti-viral activity was detectable in uterine flushings from day 16 to day 22, and increased with duration of gestation (P < 0.01) and developmental stage (P < 0.01). When interferon-tau was administered daily between day 14 and day 20 to non-pregnant hinds to mimic natural blastocyst production, luteolysis was delayed by a dose of 0.2 mg day(-1) (27.3 +/- 1.3 days after synchronization, n = 4 versus 21 +/- 0 days in control hinds, n = 3; P < 0.05). Interferon-tau was administered to hinds after asynchronous embryo transfer to determine whether it protects the conceptus against early pregnancy loss. Embryos (n = 24) collected on day 6 from naturally mated, superovulated donors (n = 15) were transferred into synchronized recipients on day 10 or day 11. Interferon-tau treatment (0.2 mg daily from day 14 to 20) increased calving rate from 0 to 64% in all recipients (0/11 versus 7/11, P < 0.005), and from 0 to 67% in day 10 recipients (0/8 versus 6/9, P < 0.01). The increased success rate of asynchronous embryo transfer after interferon-tau treatment in cervids may be of benefit where mismatched embryo-maternal signalling leads to failure in the establishment of pregnancy.

The population of Red Deer (Cervus elaphus L., 1758) in Tulcea county (Romania) The presence of the Red Deer in the North-western parts of Tulcea County is an example of the natural expansion of a species spreading area. In North Dobrogea, this mammal first occurred only forty years ago. The first specimens were spotted on Cocoşul Hill (on the territory of Niculiţel area) in 1970. Peak numbers (68 individuals) were registered in the spring of 1987. The deer population (67 specimens in 2007) of this county extended along 10 km from West to East and 20 km from North to South over a total of 23,000 ha (55% of which was forest land) in the East of the Măcin Mountains and in the West of the Niculiţel Plateau.
