The importance of trees for an invasive Mediterranean cellar slug, Limacus flavus , was studied within one block of a residential area in Kyiv city (Central Ukraine) from spring of 2020 to spring of 2021. Slugs tended to occur in the old poplars ( Populus nigra var. italica ). Live animals or their traces were found on the 71 of 320 poplars and on 17 trees of other species in the studied area. Slugs often go up to at least 12 m above the ground on these poplars and feed on the lichens there. Animals breed and spend the daytime inside at least some of these trees under the bark. Slugs were wintering in some of these trees in 2020-2021 and probably also at least in 2019-2020, while previously L. flavus was reported from Eastern Europe only in connection to cellars, basements and greenhouses. Apparently these slugs are occupying additional habitats in response to climate change and their occurrence in the trees may become common in Eastern Europe with the warming of climate. The colouration of L. flavus and closely related L. maculatus is discussed. Various differences of the colouration were suggested in the literature to distinguish the two species, most notably the central light stripe on the back of L. flavus , but this character is absent in most of the studied specimens and, therefore, the overall colouration overlaps in the studied populations of the two species.

The Standardized Precipitation Index

 Drought is one of the natural hazard risks which badly affects both agricultural and socio-economic sectors. Hungary, which is located in Eastern Europe has been suffering from different drought cycles; therefore, the aim of this study is to analyse the rainfall data obtained from ten metrological stations (Békéscsaba, Budapest, Debrecen, Győr, Kékestető, Miskolc, Pápa, Pécs, Szeged, Siófok, Szolnok) between 1985 and 2016, by using the Standardized Precipitation Index (SPI). The results showed that 2011 was recorded as the worst drought cycle of the studied period, where the SPI ranged between -0.22 (extreme drought) in Siófok, and 0.15 (no drought) in Miskolc. In a similar vein, the study highlighted the year 2010 to be the best hydrological year, when the SPI reached 0.73 (mildly wet) on average. Interestingly, the Mann-Kendall trend test for the drought cycle showed no positive trends in the study area. Finally, more investigation should be conducted into the climate change spatial drought cycle in Europe.

<p>This study focuses on the impact of climate change on rainfall-runoff pattern, and to assess the surface runoff and groundwater recharge potential from the intensified rainfall for the effective management of surface and groundwater resources in Tirunelveli city. The rainfall contribution is consistent, dependent, maximum and intensified during the month of November followed by October and December. The intensified rainfall in these months causes a temperature decrease and the climate becomes more and more colder than ever. The indices SPI and DI clear show that there is a change in climatic pattern. Landuse Landcover (LULC) analysis shows that the residential area and mining area is on the increasing trend, Village area is slightly increasing, agricultural area and dense scrub area is on the decreasing trend. The present capacity of the storage tanks available in Tirunelveli city is less than the maximum runoff generated during the month of November. The increase in residential area in LULC reflects the direct linear relation with the population increase of the city. The impact of urbanization leads to LULC change with the loss of agricultural land and water bodies.</p>

Resumen: La rapidez en el crecimiento de nuestras ciudades y municipios, y el aumento vertiginoso en la demanda de suelo urbanizable, ha originado la impermeabilización del suelo urbanizado, lo que ha producido un aumento en los caudales de escorrentía. Por otro lado, el cambio climático impone nuevos desafíos en materia de gestión del drenaje pluvial para nuestras ciudades y municipios. El municipio de Turbaco vive una problemática en materia de drenaje pluvial, por causa del aumento en la demanda de suelo urbanizable y por la impermeabilización del suelo urbanizado. Los embalses de retención y las canales verdes surgen como una alternativa para la gestión de las aguas pluviales. Estos sistemas son de fácil adaptación al medio y son soluciones que van en favor del medio ambiente, al tiempo que constituyen parte del paisaje urbano. ___Palabras clave: Inundaciones, embalses, canales verdes, análisis hidrológico, planificación urbana. ___Abstract: The rapid growth of our cities and municipalities, and the rapid increase in the demand for urbanizable land, has led to the waterproofing of urbanized land, which has led to an increase in runoff flows. On the other hand, climate change imposes new challenges in the management of storm drainage for our cities and municipalities. The municipality of Turbaco lives a problem in the matter of rainwater drainage, due to the increase in the demand of urbanizable land and the waterproofing of the urbanized land. Retention reservoirs and green channels emerge as an alternative to stormwater management. These systems are easy to adapt to the environment and are solutions that are in favor of the environment, while being part of the urban landscape. ___Keywords: Floods, reservoirs, green channels, hydrological analysis, urban planning. ___Recibido: 13 abril 2016.
