Erot spatiaalisissa ja ajallisissa reaktionormeissa kevään ja syksyn fenologisille tapahtumille

For species to stay temporally tuned to their environment, they use cues such as the accumulation of degree-days. The relationships between the timing of a phenological event in a population and its environmental cue can be described by a population-level reaction norm. Variation in reaction norms along environmental gradients may either intensify the envi- ronmental effects on timing (cogradient variation) or attenu- ate the effects (countergradient variation). To resolve spatial and seasonal variation in species’ response, we use a unique dataset of 91 taxa and 178 phenological events observed across a network of 472 monitoring sites, spread across the nations of the former Soviet Union. We show that compared to local rates of advancement of phenological events with the advancement of temperature-related cues (i.e., variation within site over years), spatial variation in reaction normsPeer reviewe

Phenological shifts of abiotic events, producers and consumers across a continent

Ongoing climate change can shift organism phenology in ways that vary depending on species, habitats and climate factors studied. To probe for large-scale patterns in associated phenological change, we use 70,709 observations from six decades of systematic monitoring across the former Union of Soviet Socialist Republics. Among 110 phenological events related to plants, birds, insects, amphibians and fungi, we find a mosaic of change, defying simple predictions of earlier springs, later autumns and stronger changes at higher latitudes and elevations. Site mean temperature emerged as a strong predictor of local phenology, but the magnitude and direction of change varied with trophic level and the relative timing of an event. Beyond temperature-associated variation, we uncover high variation among both sites and years, with some sites being characterized by disproportionately long seasons and others by short ones. Our findings emphasize concerns regarding ecosystem integrity and highlight the difficulty of predicting climate change outcomes. The authors use systematic monitoring across the former USSR to investigate phenological changes across taxa. The long-term mean temperature of a site emerged as a strong predictor of phenological change, with further imprints of trophic level, event timing, site, year and biotic interactions.Peer reviewe

Chronicles of nature calendar, a long-term and large-scale multitaxon database on phenology

We present an extensive, large-scale, long-term and multitaxon database on phenological and climatic variation, involving 506,186 observation dates acquired in 471 localities in Russian Federation, Ukraine, Uzbekistan, Belarus and Kyrgyzstan. The data cover the period 1890-2018, with 96% of the data being from 1960 onwards. The database is rich in plants, birds and climatic events, but also includes insects, amphibians, reptiles and fungi. The database includes multiple events per species, such as the onset days of leaf unfolding and leaf fall for plants, and the days for first spring and last autumn occurrences for birds. The data were acquired using standardized methods by permanent staff of national parks and nature reserves (87% of the data) and members of a phenological observation network (13% of the data). The database is valuable for exploring how species respond in their phenology to climate change. Large-scale analyses of spatial variation in phenological response can help to better predict the consequences of species and community responses to climate change.Peer reviewe

Современная численность и распространение скопы на побережьях крупных водоёмов Северо-запада России

Обширная территория (от верховьев р. Волга до севера Кольского полуострова) обследовалась в ходе летних и зимних экспедиций в период с 1998 по 2018 гг. Территория Вологодского Поозерья дополнительно обследовалась с вертолета в 1988, 1993, 1999, 2002 и 2008 гг. (38 летных часов). Всего за время работ пройдено 53060 км, в том числе: 6860 км водных маршрутов, 22500 км автомобильных маршрутов, 2370 км на снегоходе. В весенний период проводились поиски гнёзд с использованием параплана. За последние 20 лет отмечается заметное увеличению численности скопы (Pandion haliaetus) на побережье большинства крупных водоемов Северо-Запада России

Stability of Territorial Bounds in Birds of Prey as Indicator of Their Life Strategies

The level of stability of territorial bounds can act as an integral index of a life strategy, considering the ability of raptors to actively move in space as an evolutionary result of optimizing relations with the environment

Особенности осеннего миграционного поведения скоп, обитающих на Северо-западе России

С 2015 по 2017 гг. мы изучали осенние миграции скопы (Pandion haliaetus) населяющей Дарвинский государственный природный биосферный заповедник (расположен на берегу Рыбинского водохранилища в 50 км южнее города Череповец, Северо-Запад России) и его окрестности (включая побережье Онежского озера). Было помечено 4 скопы из 4 разных гнезд

Результаты работы Центра кольцевания хищных птиц Российской сети изучения и охраны пернатых хищников в 2016 году

В работе Центра кольцевания хищных птиц Российской сети изучения и охраны пернатых хищников в 2016 г. участвовали 30 орнитологов-исследователей и любителей птиц, которые окольцевали 295 птиц 23 видов соколообразных и сов в 19 субъектах Российской Федерации (Вологодская, Московская, Новосибирская, Псковская, Нижегородская, Свердловская, Ярославская, Ульяновская, Самарская, Волгоградская, Оренбургская области, Республика Алтай, Республика Татарстан, Удмуртская Республика, Чувашская Республика, Республика Тыва, Республика Хакасия, Алтайский край, Красноярский край).
