Literature as a representation of changes in urban landscapes after 1945 (on Polish, Czech and Slovak examples)
2018
The paper focuses on changes of urban and cultural landscapes after 1945 under the communist regime in a way that they were presented in Polish, Czech and Slovak literature published after 1989 (when a climate for talking about politically uncomfortable topics has changed). The main subject of the author‟s interest is how surrounding landscape influences people‟s behaviour demonstrated in literary pieces. The destruction caused during the WWII in Polish (former German) towns like Gdańsk, Szczecin or Wrocław and decision of contemporary authorities not to restore anything for many decades forced citizens to live in increasingly decaying surroundings. In Czechoslovakia, due to expulsion of Ge…

Soils, Past Landscapes and Cultural Heritage: Phytoliths as Indicators of Ancient Crops
La costruzione del paesaggio ibleo: reti deboli, segni forti
2017
The contribution deals with the theme of the dry stone walls’ landscape which characterizes the rural “Koinè” of the Hyblean plateau in South-Eastern Sicily. The essay analyses the main political-economic, social-territorial, constructive and typological features which make the dry walls network the landmark of the Ragusa province. Because of the modification of the economic-cultural context that produced it, the loss of knowledge of the construction techniques and the lack of public resources, the definition of an axiology of the contemporary landscape as premise for the establishment of adequate terms of value for the safeguard of this heritage is required.
A mate to die for? A model of conditional monogyny in cannibalistic spiders.
2012
Monogynous males in various species actively limit themselves to mating with a single female in their lifetime. Whereas previous models have considered monogyny as an obligate mating strategy, here we explore the potential of monogyny to evolve as a context-specific (conditional) behavior. Using a state-dependent dynamic game model based on the biology of the cannibalistic spider Argiope bruennichi, we confirm that conditional monogyny can evolve under broad conditions, including an even sex ratio. We predict that males should make a terminal investment when mating with large, virgin females, especially if population density is low and the encounter occurs late in the season. We encourage e…
Analysing gene flow in heterogeneous landscapes: why and how to use genetic graphs?
2019
International audience; In heterogeneous landscapes, when species occupy discrete habitat patches, ecological connectivity is influenced by populations’ topology. Graph-theoretic methods constitute a relevant tool to reveal this topology and better analyse gene flow. Despite growing interest in genetic graphs, a better understanding of when and how to use them is lacking.To fill this gap, we simulated gene flow between 50 populations in different landscape configurations and constructed genetic graphs using various genetic distances and pruning (link selection) methods. We then compared metrics derived from these graphs to analogous metrics describing the topology and connectivity of the di…
Un Parco nella Sicilia più nascosta
2021
Le aree interne della Sicilia sono caratterizzate, oltre che dalle tipiche crisi delle aree marginali, da altri fattori peculiari quali una costante arretratezza tecnologica e uno disfattismo di gattopardesca memoria. Esse sono anche però il luogo ove lo sviluppo locale potrebbe riportare i suoi migliori esiti, trasformandole da luoghi del sottosviluppo in luoghi di rinnovata e viva identità. Ciò in virtù dalla immensa potenzialità che luoghi naturali come i Parchi possiedono intrinsecamente per avviare uno sviluppo sostenibile che riesca a mantenere le componenti identitarie e paesaggistiche di un luogo e al contempo risollevarne le sorti. Il caso studio, ivi presentato, riguarda il Parco …
Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
University Exchange Students’ Practices of Learning Finnish: A Language Ecological Approach to Affordances in Linguistic Landscapes
2020
In linguistic landscape (LL) studies, various projects have demonstrated how language learners benefit from tasks that involve the documentation and interpretation of the LL. In this chapter, we investigate how Finnish as a second language learner exchange students turned the local LL into affordances during their time abroad in Finland. While language awareness and its relation to learning and teaching have been extensively discussed, it has often been regarded as a property of an individual consciousness: a faculty or a tendency of a particular person to perceive, notice and reflect upon the linguistic features present in their environments. In contrast, we argue for an approach that cont…
Tourism-related informal interaction in Chembe, Malawi : an ethnographic study
2016
Tutkielmassa tarkastellaan turismin liittyvää vapaamuotoista kanssakäymistä paikallisten malawilaisten sekä ulkomaalaisten asukkaiden ja matkailijoiden välillä. Etnografinen pääaineisto on kerätty Malawissa keväällä 2013 ja se koostuu haastatteluista ja muistiinpanoista. Tosisijainen aineisto koostuu raporteista ja asiakirjoista, joiden tarkoitus on hahmotella ruohonjuuritason vuorovaikutukselle laajempi yhteiskunnallinen konteksti. Metodologisesti tutkielma hyödyntää ranskalaisen sosiologin ja etnologin Pierre Bourdieun esittelemää käytännön teoriaa ja sen keskeisiäkäsitteitä, jotka ovat kenttä, pääoma ja habitus. Tutkielman tarkoitus on valottaa niitä tekijöitä, jotka määrittävät eri toim…
The size and shape of shells used by hermit crabs: A multivariate analysis of Clibanarius erythropus
2009
Shell attributes such as weight and shape affect the reproduction, growth, predator avoidance and behaviour of several hermit crab species. Although the importance of these attributes has been extensively investigated, it is still difficult to assess the relative role of size and shape. Multivariate techniques allow concise and efficient quantitative analysis of these multidimensional properties, and this paper aims to understand their role in determining patterns of hermit crab shell use. To this end, a multivariate approach based on a combination of size-unconstrained (shape) PCA and RDA ordination was used to model the biometrics of southern Mediterranean Clibanarius erythropus populatio…
