“…Frogs and other amphibians are poikilothermic and also fairly sedentary (Tryjanowski et al, 2003). Their inability to regulate their own body temperature makes them particularly sensitive to the temperature of their environment (Tryjanowski et al, 2003;Chadwick et al, 2006;Sparks et al, 2007a). It has been shown that there is a strong relationship between air and water temperature and amphibian life-cycle events such as emergence from hibernation and initiation of breeding (Beebee, 1995;Reading, 1998;Carey & Alexander, 2003;Tryjanowski et al, 2003;Chadwick et al, 2006).…”

Between 1998 and 2007, the UK Phenology Network collected nearly 70 000 records of the first spawn dates of the common frog Rana temporaria. Annual national mean dates varied by more than 2 weeks and were closely related to January-March temperatures. A 1 1C increase in Central England Temperature advanced national mean spawning by 5.1 days. The temporal pattern of spawning records varied between years; sometimes unimodal in form, sometimes multimodal, seemingly associated with steady or erratic rises in spring temperatures, respectively. Spatial patterns of frogspawn were similar in different years, the earliest records occurring in the southwest with records progressively later in the north and east. On average, 100 km of eastwards progression took 7.4 days and 100 km of northwards progression took 4.7 days. A composite map for the 1998-2007 period is constructed and compared with an earlier published map based on data 60 years previously. The similarity and dissimilarity of these two maps is discussed; the general progression pattern of frogspawn phenology is similar but an advance of a 10-day contour category is apparent. We anticipate further advances of frog spawning dates in the future and an increase in the numbers of pre-January 1 records of frog breeding.

“…Причем, температурные адаптации локальных по-пуляций конкретных видов, особенно у холоднокровных животных, могут быть существенны для оценки масштабов временного сдвига фенологических фаз ре-продуктивного цикла (Sparks et al, 2007). Исследование многолетней динамики фенологии периода зимовки позволит оценить влияние трансформации климата в течение продолжительного периода времени, а также провести анализ последствий этих изменений для современного экологического состояния и перспектив локаль-ных популяций конкретных видов бесхвостых амфибий.…”

Поступила в редакцию 18.08.15 г.Фенологические изменения зимовки чесночницы обыкновенной -Pelobates fuscus (Pelobatidae, Amphibia) в условиях трансформации климата на севере Нижнего По-волжья. -Ермохин М. В., Табачишин В. Г., Иванов Г. А. -Рассматриваются закономер-ности изменения календарных дат начала, окончания и продолжительности зимовки чес-ночницы обыкновенной (Pelobates fuscus) в долине р. Медведица (Лысогорский район, Са-ратовская область) в период с 1892 до 2014 г. Показано сокращение продолжительности зи-мовки в среднем на 7 сут. за последние 120 лет, обусловленное сдвигом даты начала зимов-ки на более поздние сроки и даты окончания зимовки на более ранние сроки. Изменения да-ты окончания зимовки начали формироваться в основном с 1950-х гг., а начала зимовки -в 1980-х гг. и значительно ускорились в 2002 -2014 гг. Периодичность изменения даты нача-ла и окончания зимовки обусловлена в основном циклами суровости зим (8-9 лет) и водно-сти -засушливости (циклы Брикнера: 36 -38 лет). В результате анализа температурного режима в почвенном профиле показано, что сокращение продолжительности зимовки обу-словлено в основном за счет более раннего начала нерестовых миграций половозрелых осо-бей данного вида в весенний период. Глубина залегания особей данного вида в почвенном профиле устойчиво сокращается с начала 1980-х гг. до 2014 г. Разработаны прогностиче-ские модели, позволяющие предполагать прекращение перемещения особей данного вида в почвенном профиле из горизонтов, в которых они находятся в период активности, к 2050 г., а также значительное сокращение продолжительности зимовки или даже возможное ее пол-ное исчезновение как фазы годового цикла в течение 315 лет при сохранении современного климатического тренда.Ключевые слова: Pelobates fuscus, фенология, зимовка, трансформация климата, Сара-товская область.Phenological changes of the wintering of Pelobates fuscus (Pelobatidae, Amphibia) in the climate transformation conditions of the northern Lower-Volga region. -Yermokhin M. V., Tabachishin V. G., and Ivanov G. A. -Regularities of the changes of calendar dates of the start, end and duration of Pelobates fuscus wintering in the Medveditsa river valley (Lysogorsky district, Saratov region) within the period from 1892 until 2014 are considered. A reduction of the wintering duration by 7 days (on the average) over the last 120 years is shown, due to a shift of the start wintering date to a later date and that of the end wintering date to an earlier date. Such changes of the end and start wintering dates mainly began to emerge since the 1950s and 1980s, respectively,

“…Common species with wide distributions are useful for research, as it is relatively easy to obtain sufficiently large samples and to conduct research on a large spatial scale (Sparks et al 2007). In Europe, including Poland, one of the most widespread species, but also one of the most vulnerable to road mortality, is the common toad Bufo bufo (Głowaciński and Rafiński 2003; Elzanowski et al 2009; Temple and Cox 2009) .…”

Every spring, many of amphibians are killed by motor vehicles on roads. These road-killed animals can be used as valuable material for non-invasive studies showing the effect of environmental pollution on amphibian populations. The aims of our research were to check whether the phalanges of road-killed toads may be useful as material for histological analysis, and whether various degrees of human impact influence the level in bone abnormalities in the common toad. We also examined whether the sex and age structure of toads can differ significantly depending in the different sites. We chose three toad breeding sites where road-killed individuals had been observed: near the centre of a city, the outskirts of a city, and a rural site. We collected dead individuals during spring migration in 2013. The sex of each individual was determined and the toes were used to determine age using the skeletochronology method. While performing age estimates, we looked for abnormalities in relation to normal bone tissue structure. In urban site, females dominate males (sex ratio 2.6:1), but in populations from rural and semi-urban sites, sex ratio was reverse (1:2.2 and 1:1.4, respectively). However, we did not find any significant differences between age structure of all populations (average age of each population: approximately 4 years). We observed abnormalities in more than 80 % of all toads from the city, compared to approximately 20 % from the rural and semi-urban sites. In particular, we found hypertrophic bone cells, misaligned intercellular substance, and irregular outer edges of bones. We suggest that these malformations are caused by different pollution, e.g. with heavy metals.
