Factors determining natural regeneration of yew (Taxus baccata L.) in the Kórnik Arboretum

All yew plants in the Kórnik Arboretum have been plotted onto maps of individual sectors and analysed with respect to location category (“near trunk”, “under canopy”, “in the open”), size (assumed to reflect age), genus of tree associated with in the “near trunk” category and environmental factors characterising the respective Arboretum sectors. There is practically no regeneration “in the open” (0.2%), most of it 82.5% is “under canopy” and only 17.3% “near the trunk”. It is assumed that thrushes (Turdidae) are primarily responsible for regeneration in the under canopy category (endozoochoria) and nuthatches (Sitta europea L.) in the near trunk category (synzoochoria). Under canopy regeneration exists in all size classes while near the trunk there is a distinct decline in the number of yew plants with increase in size (age) suggesting that conditions for further development there are less favourable. Nutchatches disperse yew seeds in the vicinity of mother plants, for cleaning them preferring trees to shrubs and particularly trees with smooth bark trunks (Fagus, Carpinus), however yew survival near the trunk is better under conifers. Thrushes disperse yew seed over wider areas. Survival of yews is best under loose canopies, in moderate shade, on drier well draining, low pH, soils.

The forest Blackbirds in the Białowieża National Park constitute a migratory, monogamous, double-brooded population with a low frequency of inter-male and inter-female aggression. During most years they meet good feeding conditions reflected in: a large clutch size (4.5, in May even 4.8), high amount of food brought to nestlings, intensivemid-day feeding them, rarity of nestling starvation. Nesting losses (50-92%, mean 68%) were in 98% caused by predation or a threat of it. An average nest produced 1.3 nestlings, at a variable nesting success (8-50%). On average 2.5 young per pair fledged yearly; the most successful pairs reared 8-9 young. Nesting losses varied (50-81%) between habitats, seasons and years. The predators switch to other prey: in a low-rodent year they killed four times more Blackbird nestlings than in a rodent year, and in high-caterpillar years smaller predators left more bird eggs undestroyed. Breeding ecology of Blackbirds in the primaeval forest is shaped mostly by a strong predation pressure varying in space and time.

In the Białowieża National Bark, NE Boland, the Blackbird populates the whole extensive forest as a forest-interior species. The following mean densities were recorded in primaeval stands: 2.5 pairs/10 ha in riparian ash-alder, 2.2 in oak-lime-hornbeam and 0.7 p/10 ha in conifer-dominated stands. An approximate territory size was 1.1 -4.3 ha, usually 22-2.7 ha, which is 11 -43 times smaller of that found in Oxford Botanical Garden and some С-European urban parks. The density along the forest edge was slightly higher in some years only. In primaeval stands the species nests in trees, often in tree-holes, on average 5.3 (0.3-24) m above the ground. Nests placed above 7.5 m were twice more successful than the lower ones. The Blackbird's nesting in low bushes appears to be a feature reinforced under anthropogenic conditions, like its preference for the forest edge or its foraging in the open. It is argued that the Blackbird was primarily a species of old high-stemmed lowland and submontane forest.

A new coccidian species (Protozoa: Apicomplexa: Eimeriidae) are reported from the white-necked thrush Turdus albicollis Vieillot, 1818, a very common species in South America. Isospora massardi sp. nov. oocysts are subspherical, 18.6 × 17.7 μm, with smooth, bilayered wall, ∼0.9 μm. Micropyle, oocyst residuum are absent, but two polar granules are frequently present. Sporocysts are ovoidal, 14.8 × 9.3 μm. Stieda body is knob-like to rounded and substieda body is rounded. Sporocyst residuum is composed of scattered spherules of different sizes. Sporozoites are vermiform with posterior and anterior refractile bodies and a nucleus. This is the sixth description of an isosporoid coccidium infecting a New World turdid bird.
