Tavole di cubatura di popolamento per i soprassuoli forestali della Sicilia.
2009
Obiettivo del lavoro e la messa a punto di tavole di cubatura di popolamento per la stima statistica, in maniera rapida, facilmente applicabile e con adeguata attendibilita, delle masse legnose dei boschi ordinariamente governati a ceduo e a fustaia. Nella presente nota viene illustrata l’analisi statistica condotta per la preparazione dei modelli matematici di predizione del volume della massa legnosa a ettaro, vengono riportati i risultati ottenuti e sono discusse le modalita di applicazione dei modelli elaborati. L’impiego delle tavole di popolamento e indicato soprattutto nelle situazioni in cui sia possibile adottare procedure speditive per la determinazione dell’area basimetrica per u…
Verifica del merito creditizio, responsabilità del finanziatore e "indebitamento incauto"
2014
La tesi analizza la nuova disciplina europea sul credito ai consumatori, introdotta dalla direttiva 2008/48/Ce, recepita nel nostro ordinamento con il d.lgs. n. 141/2010, che ha modificato il Testo unico bancario (d.lgs n. 385/1993). In particolare, si sofferma sull'obbligo di verifica del merito creditizio, previsto dall'art. 124 bis Tub, e sulla responsabilità del finanziatore che concede credito senza osservare il disposto della norma suddetta. Dopo aver ascritto alla responsabilità "da contatto sociale" la condotta del prestatore che concede credito in maniera poco accorta (non senza precisare che in ultima istanza la concessione disinvolta di credito avrà riflessi sulle condizioni cont…

WHO BEARS THE COSTS OF INTERSPECIFIC COMPETITION IN AN AGE-STRUCTURED POPULATION?
2003
Social and density-dependent life history processes may differ according to age and the reproductive history of individuals. Arvicoline rodents have a typical, season-dependent, bimodal, age distribution of breeding individuals within a population. This distribution may influence population fluctuations. In this study, we measured effects of interspecific competition from field voles (Microtus agrestis) on various fitness components of female bank voles (Clethrionomys glareolus) in an age-structured breeding population in large (0.25 ha) outdoor enclosures. We monitored survival, reproduction, and space use of experimental bank vole populations with females from two different age groups. Wi…
Effects of fragmented breeding habitat and resource distribution on behavior and survival of the bank vole ( Myodes glareolus )
2010
Habitat fragmentation causes negative population trends or even local extinction in many species. Understanding the role of fragmentation on behavior and space use of animals is an essential part of revealing the mechanism behind observed population declines. We studied experimentally the effects of small-scale habitat fragmentation on the distribution and movement of bank voles (Myodes glareolus) in seminatural enclosures. We predicted that besides habitat structure, availability of two resources, food for both sexes, and receptive females for males, determine individual distribution. We manipulated female density (either 0, 4, or 12 per enclosure) and followed movements of radio-collared …
Social overwintering and food distribution in the bank vole Clethrionomys glareolus
1991
We studied overwintering in the bank vole Clethrionomys glareolus in four 0.5 ha enclosures in an abandoned field in central Finland in the winter 1987/88. In two of the enclosures food was offered evenly distributed over the whole enclosed area (Even Enclosures = EE), in the two others food was offered in one feeding patch with four feeding chambers 2 m apart (Patchy Enclosures = PE). Food was provided in about the same amount in both enclosures. The experiment commenced in early October, with 13 females and 11 males in EEs and 12 + 13 voles in PEs. After two months the voles in the PEs were concentrated around the feeding patches. Territoriality was not observed in EEs, instead the voles …
Food resources and intestinal parasites as limiting factors for boreal vole populations during winter
2014
Processes limiting the growth of cyclic vole populations have stimulated considerable research and debate over several decades. In Fennoscandia, the peak density of cyclic vole populations occurs in fall, and is followed by a severe winter decline. Food availability and intestinal parasites have been demonstrated to independently and synergistically limit wildlife populations. The purpose of this study was to directly compare competing food and parasite hypotheses on the limitation of overwintering high-density vole populations. Moreover, we evaluated the ability of food limitation and nematode infection to interact and thereby intensify population declines. A two-factor experiment with foo…
Breeding suppression in the bank vole as antipredatory adaptation in a predictable environment
1994
In northern Fennoscandia, microtine rodent populations fluctuate cyclically. The environment of an individual vole can be considered to be predictable when the risks of predation and intra- and interspecific competition change with the cycle, such that both are high during the population highs of voles. The risk of predation is also high during the vole crash. After the crash, the vole population is characterized by low intra- and interspecific competition and low predation pressure. The main predators affecting voles during the crash are the small mustelids, least weasel and stoat. The density of these specialist predators declines drastically during the winter after the vole crash. We stu…
