“…Thus, regular feeding of reindeer every winter may lead to a biased selection of individuals that prefer feeding in front of natural pasture, while reducing the selection pressure on important traits needed for winter survival on natural pasture (Schmidt & Hoi 2002;Rodriguez-Hidalgo et al 2010). A long-term effect of regular feeding may therefore be selection of animals with a tolerance for anthropogenic conditions (feeding) and animals acquiring new adaptions, such as searching for feed provided by herders rather than selection for animals possessing the skills to find natural forage (Shydlovskyy & Kuzyo 2016), another form of evolutionary trap. This is beneficial if feeding continues to be used on a regular basis, and to buffer density and climate effects, but risks reducing natural selection pressure and the phenotypic plasticity needed for animals to survive under natural conditions by buffering against environmental variation.…”

Winter feeding of reindeer (Rangifer tarandus tarandus) has become an increasingly common management action in reindeer husbandry in Sweden, Finland, and Norway when natural grazing resources are unavailable due to the loss of grazing grounds, disturbances, and icing events. In the short term, feeding increases survival and reproduction, but the long-term effects on reindeer’s ability to utilize natural pastures have not been investigated. Herders have raised concerns that fed reindeer, especially calves, do not utilize natural pastures as efficiently as other reindeer. In this thesis, I investigated the short- and long-term effects of winter feeding on reindeer with focus on habitat selection and future foraging behaviour. Interviews were conducted to collect experience-based knowledge on the effects of feeding among reindeer herders. An experimental study was conducted to test how winter feeding of calves during their first winter affects future habitat selection, foraging behaviour, and body weight. I found that there are several unintended effects of feeding that may compromise reindeer’s ability to use the natural pastures efficiently. In the interviews, the effects identified by herders were related to physical traits or behaviour; the reported effects varied between herders, as did the perception of whether an effect was positive or negative. In the experimental study, I found that reindeer calves which were fed in enclosures during their first winter of life were less likely to select areas with higher lichen abundance when on natural pasture compared to reindeer that had spent their first winter on natural pasture. Although, the control animals were also provided feed on pasture to some extent their first winter. Understanding the long-term impacts of winter feeding on reindeer and their ability to utilize natural pastures and adapt to changes in the environment may be crucial when evaluating the effects of different external forces on reindeer husbandry. Knowledge of the short- and long-term effects of feeding on reindeer is important for herders when evaluating if, when and how to feed their reindeer.

Introduction. Information on historical changes in the fauna of geographical regions and biota habitats is important for understanding the processes that take place in ecosystems. The results of such an analysis in combination with modern research can indicate not only the global trends in changes of animal associations and the status of particular populations of species, but also reveal the reasons that caused the situation. Materials and discussion. The first lists of bird species in the 18th – early 19th centuries showed the nesting of 12 species of waders. However, during the 19th century 37 species of waders were found, 12 of which were nesting. 13 wader species were permanent migratory and 8 – rare migratory species. In the first half of the 20th century, there were 27 species of waders on the territory of Prykarpattia, and 25 in Volyn, among which there is a larger list of migratory and vagrant species in the foothills of the Carpathians. In the second half of the 20th century, 39 species of waders were described within the western regions of Ukraine, of which 17 were nesting, and four of them were recorded during the last decade. Conclusions. There are 42 species of waders (39 of them are recent) registered in the western part of Ukraine. Among them 17 species are nesting, 15 – migratory and seven – vagrant species. During the 20th–21st centuries, 23 species of waders, including only 7 nesting species, have not changed their status of stay. However, it has changed for 17 species: two species have disappeared; four – have become vagrant; the Ruff Calidris pugnax and the Marsh Sandpiper Tringa stagnatilis have changed their status from nesting to migratory. The Northern Lapwing Vanellus vanellus, the Green Sandpiper Tringa ochropus and the Wood Sandpiper T. glareola that were common, somewhere numerous bird, – have become few in numbers; and the Great Snipe Gallinago media and the Black-tailed Gotwit Limosa limosa – have become rare. The Jack Snipe Lymnocryptes minimus has become migratory. The nesting of sandpipers, with a southern area of distribution, in the western regions of Ukraine proves the fact of the global warming. However, the drop of the water level, drying out of wet meadows and swamps and, as a consequence, plant succession, have terminated the nesting of such species as the Ruff and the Marsh Sandpiper; the Black-tailed, the Great Snipe and the Wood Sandpiper become rare; the Northern Lapwing and the Green Sandpiper have become much less numerous.

“…In recent decades the Northern Lapwing Vanellus vanellus, (hereafter: lapwing) has, along with many other European ground-nesting waders, experienced a strong decline across Europe (Milsom 2005, Donald et al 2006, Roodbergen et al 2012, Plard et al 2020), including the central and eastern lowlands, which are traditionally known to support strong grassland wader populations (Žídková et al 2007, Ławicki et al 2011, Shydlovskyy & Kuzyo 2016, Mischenko 2020). The European lapwing population is currently estimated at about 1.59-2.58 million pairs, with a substantial decreasing trend of 30-49% over the last 27 years (BirdLife International 2021).…”

The field studies were conducted in three ephemeral river islets of the middle Pripyat River, southern Belarus in 2006–2007. Nestlings of the Northern Lapwing (Vanellus vanellus) were ringed soon after hatching, and reencountered during subsequent visits. Post-hatching survival was estimated by capture-mark-recapture models. Daily survival rates of the Northern Lapwing chicks were very high, varying between 0.90 and 0.99, and the cumulative survival rates over 35 days between hatching and fledging were 0.54 and 0.70 in 2006 and 2007, respectively. Survival rate was lower in the first ten days of life, which is similar to that reported in other precocial species. The key factor supporting this high breeding success is low predation due to nesting of lapwings on periodic river islets that naturally restrict access by mammalian predators and apparent scarcity of terrestrial and avian predators. River islet habitats with co-occurrence of dry and wet fertile microhabitats provide optimum feeding conditions for the Lapwing chicks with a wide range of aquatic, ground and surface invertebrates. Moreover, semicolonial breeding of the Northern Lapwing (about 30 nests/ha) with other waders, terns and gulls increases the effectiveness of anti-predator behaviour. Consequently as a result of low predation pressure and good foraging conditions, in 2006 and 2007, productivity was 2.1 and 2.8 fledged young per single nest with four chicks respectively, a value hardly reported in Europe, except in managed sites.
