Pathways for the amplification of agroecology in African sustainable urban agriculture
2020
A growing awareness that highly intensified agricultural systems have made a substantial worldwide contribution to the worsening of the resilience capacity of natural ecosystems has, over the last twenty years, brought general attention to agroecological management models. This aspect is even more evident in industrial agriculture, which is based on the use of multiple chemical products derived from non-natural synthesis. In more developed countries, a new idea of ecology linked to agricultural production has been increasingly developed and, for this reason, there has been a greater diffusion of differentiated agricultural models taking into consideration the environmental impact of product…
The Effect of Predator Population Dynamics on Batesian Mimicry Complexes.
2022
Understanding Batesian mimicry is a classic problem in evolutionary biology. In Batesian mimicry, a defended species (the model) is mimicked by an undefended species (the mimic). Prior theories have emphasized the role of predator behavior and learning as well as evolution in model-mimic complexes but have not examined the role of population dynamics in potentially governing the relative abundances and even persistence of model-mimic systems. Here, we examined the effect of the population dynamics of predators and alternative prey on the prevalence of warning-signaling prey composed of models and mimics. Using optimal foraging theory and signal detection theory, we found that the inclusion …
Regional metacommunities in two coastal systems: spatial structure and drivers of plant assemblages
2014
Aim Biogeographical patterns in metacommunities are still poorly understood, and different processes are expected to occur in different habitats. We analysed the regional plant metacommunities of coastal habitats to test whether (1) the influence of space and climate differs between two habitats differentiated along the seashore–inland gradient, and (2) regional variation in species composition of these habitats can be ascribed to different metacommunity paradigms. Location The entire coast of the Iberian Peninsula, south-western Europe. Methods We collected data on the plant species composition of coastal sites on sand dunes across 3000 km of coastline. The sites were classified into two h…

Mobility of Cultures and Knowledge Management in Contemporary Europe
2012
In the aftermath of the fall of the Iron Curtain, the European Union (EU) has included more and more new member states from Central and Eastern parts of the European continent. This enlargement process has increased the cultural diversity of the European community as new languages and minority groups have been subsumed into the EU. It is the purpose of this article to discuss the challenges that result from the EU's enlargement, together with the added intra-European mobility of cultures, that affect the national knowledge infrastructures. Based on recent social scientific scholarship on mobility and cultures, this article proposes that knowledge management in contemporary Europe is not onl…
¿Existe violencia en las parejas del mismo sexo?
2010
El presente artículo intenta dar respuestas a preguntas relacionadas con la existencia o inexistencia de violencia en parejas del mismo sexo. Al igual que intenta explicar cómo es esta violencia, a qué es debida, y si es similar a la violencia que ejercen los hombres contra las mujeres. Concluyendo el mismo, con diferentes propuestas de trabajo en relación a la violencia que se da dentro de las parejas del mismo sexo a nivel individual, familiar, grupal y comunitario. This article sets out to provide replies to questions connected with the existence or nonexistence of violence in same-sex couples. It likewise attempts to explain what this violence is like, what its causes are, and whether t…
Cultural heritage in social media : Museum of Photography
2012
The research Cultural Heritage in Social Media: Museum of Photography deals with a new form of displaying and preserving cultural heritage in the 21st century by using social media tools. This paper is an analysis of a Romanian cultural heritage blog, Museum of Photography, which contains documentary photography from the end of the 19th century until 1990’s as well as other types of photographs related to the interests’ of Alex Galmeanu – the owner of Museum of Photography. The aim of this research is to demonstrate that cultural heritage exists outside the boundaries of formal institutions, namely museums, thus showing that the meaning of the word “museum” is expanding and that the public …
Tiešsaistes spēles (ne)produktivitāte: gadījuma pētījums par radošumu
2022
Bakalaura pētījums “Tiešsaistes spēles (ne)produktivitāte: gadījuma pētījums par radošumu” fokusējās uz radošajiem procesiem, ko piedzīvo galda spēles Dungeons and Dragons spēlētāji veidojot virtuālās pasaules un veidiem kā radošums izpaužas, kad spēle ir situēta tiešsaistes vidē. Iesaistoties Dungeons and Dragons kopienā, izmantojot līdzdalīgu novērojumu, neformālas diskusijas un daļēji strukturētas intervijas, es pētu dažādus artefaktu veidošanās procesus un digitālo tehnoloģiju ietekmi uz mūsu socializāciju tiešsaistē. Radošums ir improvizēts un ir mūsu sociālās un kultūras dzīves neatņemama sastāvdaļa, kas veido gan mūs pašus, gan esošās struktūras.
Spatiotemporal and gender‐specific parasitism in two species of gobiid fish
2018
Abstract Parasitism is considered a major selective force in natural host populations. Infections can decrease host condition and vigour, and potentially influence, for example, host population dynamics and behavior such as mate choice. We studied parasite infections of two common marine fish species, the sand goby (Pomatoschistus minutus) and the common goby (Pomatoschistus microps), in the brackish water Northern Baltic Sea. We were particularly interested in the occurrence of parasite taxa located in central sensory organs, such as eyes, potentially affecting fish behavior and mate choice. We found that both fish species harbored parasite communities dominated by taxa transmitted to fish…
Citizen Response in Crisis : Individual and Collective Efforts to Enchance Community Resilience
2014
This paper reports on the process and findings of an extensive research project with the aim of investigating present initiatives and approaches within the area of community resilience and citizen involvement. The paper specifically addresses which emerging sociotechnical approaches can be discerned within these initiatives. The discussion is structured within three categories of potential voluntary engagement; organized volunteers, semiorganized individuals, and “nonorganized” individuals. The empirical material assembled in the research project is contrasted with contemporary international research literature regarding sociotechnical means for enhancing community resilience. Swedish appro…
