Colonization and development of Oribatida mite communities (Acari: Oribatida) in the forest reclaimed limestone mine dumps

In order to study the colonization and development of moss mites (Oribatida) communities in a Scots pine forest of a reclaimed limestone mine dump in Northern Poland, 3 plots from the dump were chosen. The selected plots differed in age, 5 years old, 35 and 50 years old. From a total of 30 samples 499 mites (Acari) were extracted in Tullgren funnel from which 262 were Oribatida. Abundance (N) was analyzed in all mites and after determining the species of both, juvenile and adult stages of oribatids, the following indices were analyzed: Abundance (N), Dominance (D), Species diversity (S), Species richness (s) and Shannon’s diversity index (H). Regarding to the results obtained; oribatid mites were dominant with the highest abundance in all assemblages (Plot 1: 139 Oribatida /299 Acari. Plot 2: 40/55 and Plot 3: 83/145). Tectocepheus velatus showed a very high dominance (45,99%) in plot 1; the highest value for Shannon’s diversity index belonged to plot 3. On the other hand, juvenile’s percentage was significantly higher than adult’s percentage, especially at plot 2 (95,02%). These results made us to conclude that the high abundance of oribatids in the youngest forest is due to T. velatus’s high abundance and that plot 3 is the best habitat for mites. Finally, the high occurrence of juvenile stages requires keeping on studying the area.

Kautxu birziklatuzko materialek inpaktura duten erantzunaren simulazioa.

[EU]Ondorengo lanean ingeniaritzaren eremuan aurkitzen den eginkizunik garrantzitsuenetako bat egingo da: material berri bat karakterizatu. Hau da, errealitatean ikusten duguna era matematiko batean idatzi, edo beste era batean esanda, modelo matematiko bat lortu. Jorratuko den materiala kautxu birziklatua izango da, pneumatiko zaharretatik abiatuz egiten dena. Material honek, besteak beste, hurrengo abantailak ditu: produzitzeko erraza (beraz, prezio ekonomikoak, lehengaiak hondakin solidoak direla ikusita) eta inpakturako erantzun ona. Kautxu hau, beste erabileren artean, segurtasun-errailetan erabiltzen da, moto-gidariak ebaketetatik babesteko. Modelo matematikoa edo konstitutiboa lortzeko, lege hiperelastiko eta biskoelastikoetatik abiatuz, portaera bisko-hiperelastikorako lege bat proposatuko da. Lege hau deformazio handietarako eta deformazio abiadura handietarako aplikatu egingo da. Honen oinarria aurreko urteetan eskola honetako beste ikasleek eginiko gradu eta karrera amaierako lanak izango dira. Behin hau izanda, elementu finituetako software baten bidez simulatuko da, eta emaitza numerikoak esperimentalekin alderatuko dira. Honen bidez, modeloa hobetu ahal izango dugu, zehaztasun gehiago lortzeko asmoz.
