Metabolic plasticity of mixotrophic algae is key for their persistence in browning environments
2022
Light availability is the main regulator of primary production, shaping photosynthetic communities and their production of ecologically important biomolecules. In freshwater ecosystems, increasing dissolved organic carbon concentrations, commonly known as browning, leads to lower light availability and the proliferation of mixotrophic phytoplankton. Here, a mixotrophic algal species (Cryptomonas sp.) was grown under five increasing dissolved organic carbon concentrations to uncover the plastic responses behind the success of mixotrophs in browning environments and their effect in the availability of nutritionally important biomolecules. In addition to the browning treatments, phototrophic, …
L’esprit de patrimoine
2010
« Esprit objectif » (Paul Veyne), le patrimoine est de ces institutions de production de significations qui instituent une sorte de familière étrangeté, nécessaire, toujours disponible et jamais épuisée. Aujourd’hui il traverse l’art, l’architecture, l’histoire, la mémoire, la culture, la nature, met en jeu tout à la fois les droits à la mémoire, au temps, à la culture comme un devoir de gestion négociée de la nature et se concrétise dans autant de topiques qui coexistent sans forcément s’accorder. On en parcourt ici quatre : le monument, le lieu, la culture et le vivant, en suivant le fil de la pédagogie : « À quoi ça conduit ? », « comment ça agit ? » De l’examen de quelques « objets », s…
Genome-wide mapping of signatures of selection using a high-density array identified candidate genes for growth traits and local adaptation in chicke…
2023
Abstract Background Availability of single nucleotide polymorphism (SNP) genotyping arrays and progress in statistical analyses have allowed the identification of genomic regions and genes under selection in chicken. In this study, SNP data from the 600 K Affymetrix chicken array were used to detect signatures of selection in 23 local Italian chicken populations. The populations were categorized into four groups for comparative analysis based on live weight (heavy vs light) and geographical area (Northern vs Southern Italy). Putative signatures of selection were investigated by combining three extended haplotype homozygosity (EHH) statistical approaches to quantify excess of haplotype homoz…
Environmental Conflicts and Social Innovation on the Balearic Islands (Spain)
2022
New environmental conflicts arise all the time as a consequence of the industrial economy and economic growth. The search for new energy and new materials jeopardizes the margin to promote sustainable development in many local communities. In this paper, we examine a conflict related to hydrocarbons projects in the Balearic Sea (Spain) from the social innovation perspective. This novel approach allows us to focus on how socially innovative responses can be triggered by environmental threats. A set of mixed methods (qualitative analysis and social network analysis) are implemented to study the emergence and development of Alianza Mar Blava in Ibiza–Formentera. This is an initiative that succ…
Assessment of microplastics and other contaminants in marine vertebrates from the Western Mediterranean Sea
2023
Mediterranean marine biodiversity is under threat by pollution. For this reason, the main objective of this thesis was to analyse the presence of pollutants of concern in Mediterranean marine species. These studies are located in the Valencian Community (Spain), where we find loggerhead turtles, striped dolphins, and jewel lanternfish. Hence, we: 1. Analysed pesticides, heavy metals and phthalates in tissues of loggerhead turtles. 2. Studied microdebris present in beaches that are sporadically used as nesting grounds by loggerhead turtles. 3. Analysed striped dolphins# exposure to microplastics. 4. Quantified jewel lanternfish exposure to microplastics and tested their role as bioindicators…
Impact of Conservation Policies on Households’ Deforestation Decisions in Protected and Open-Access Forests: Cases of Moribane Forest Reserve and Ser…
2022
Tropical deforestation is considered a global priority due to its environmental, social, and economic impacts at international, national, and household levels. Conservation policies constitute one of the pathways to reverse this scenario. This paper examines the influence of forest protection measures on local communities’ livelihood decisions regarding forest clearing. It compares deforestation, access to forest resources, and households’ strategies in protected and open-access forests: the Moribane Forest Reserve (MFR) and Serra Chôa (SCH), two environmentally sensitive areas with different conservation statuses in Manica Province, central Mozambique. Socioeconomic data were collected fro…
Environmental values in industrial marketing relationships
2017
Concern for the natural environment has become an issue that virtually all companies have to address. Literature suggests that an environmentally oriented marketing strategy, such as an environmental brand image, yields competitive advantage for the supplier in the form of improved customer outcomes and financial performance. At the same time, key barriers to environmental purchasing are found to be related to higher perceived cost and lack of environmental interest among purchasing professionals. In addition, research has repeatedly revealed a gap between customers’ environmental values and attitudes and their manifestation in purchasing behavior. This dissertation contributes to the inter…

W pułapce samotności : pracownik socjalny wobec wykluczenia samotnych seniorów z lokalnej przestrzeni społecznej
2017
Pracownicy socjalni w swojej codziennej pracy spotykają ludzi, którzy nie radzą sobie sami z otaczającą ich rzeczywistością. Starają się więc pomóc im w samodzielnym pokonywaniu napotkanych trudności. Czynią to na różne sposoby przy zastosowaniu metod pracy socjalnej, z których najczęściej stosowane są metody pracy z indywidualnym przypadkiem i grupą (rodziną). Najrzadziej wykorzystują w realizacji powierzonych im zadań metodę organizowania środowiska. Jedną z przyczyn wykluczenia społecznego jednostki jest brak trafnej diagnozy powodów, dla których jednostki izolują się od funkcjonujących w ich przestrzeni społecznej innych ludzi. Zamykają się w swoich domach, izolują od życia w szerszych …
