Management of Alluvial Forests Included in Natura 2000 91E0* Habitat Type in Maramureş Mountains Nature Park
2015
Abstract The Natura 2000 habitat type 91E0* Alluvial forests of Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae) include three subtypes of forests. In the Maramureș Mountains Nature Park (MMNP) the alluvial forests are represented by Alnus incana forest situated on the banks of mountain rivers. Starting from 2007, 70% of the MMNP is also a Natura 2000 site of community interest. In the standard form for the site are listed 18 Natura 2000 habitat types, but that of alluvial forests 91E0* is not listed either due to an error or lack of available research data. Our study seeks to provide information regarding this high conservation value habitat such as: str…
Spatiotemporal monitoring of the rare northern dragonhead (Dracocephalum ruyschiana, Lamiaceae) — SNP genotyping and environmental niche modeling her…
2022
The species we have studied the spatiotemporal genetic change in the northern dragonhead, a plant species that has experienced a drastic population decline and habitat loss in Europe. We have added a temporal perspective to the monitoring of northern dragonhead in Norway by genotyping herbarium specimens up to 200 years old. We have also assessed whether northern dragonhead has achieved its potential distribution in Norway. To obtain the genotype data from 130 herbarium specimens collected from 1820 to 2008, mainly from Norway (83) but also beyond (47), we applied a microfluidic array consisting of 96 SNP markers. To assess temporal genetic change, we compared our new genotype data with exi…
Sequence variation and regulatory variation in acetylcholinesterase genes contribute to insecticide resistance in different populations of Leptinotar…
2021
Abstract Although insect herbivores are known to evolve resistance to insecticides through multiple genetic mechanisms, resistance in individual species has been assumed to follow the same mechanism. While both mutations in the target site insensitivity and increased amplification are known to contribute to insecticide resistance, little is known about the degree to which geographic populations of the same species differ at the target site in a response to insecticides. We tested structural (e.g., mutation profiles) and regulatory (e.g., the gene expression of Ldace1 and Ldace2, AChE activity) differences between two populations (Vermont, USA and Belchow, Poland) of the Colorado potato beet…
Reed Warbler Hosts Do Not Fine-Tune Mobbing Defenses During the Breeding Season, Even When Cuckoos Are Rare
2021
Hosts of brood parasitic cuckoos often employ mobbing attacks to defend their nests and, when mobbing is costly, hosts are predicted to adjust their mobbing to match parasitism risk. While evidence exists for fine-tuned plasticity, it remains unclear why mobbing does not track larger seasonal changes in parasitism risk. Here we test a possible explanation from parental investment theory: parents should defend their current brood more intensively as the opportunity to replace it declines (re-nesting potential), and therefore “counteract” any apparent seasonal decline to match parasitism risk. We take advantage of mobbing experiments conducted at two sites where reed warblers (Acrocephalus sc…
DETERMINANTS OF EDUCATIONAL ADVANCEMENT OF RURAL AREAS IN POLAND
2017
The article is an aimed attempt at the diagnosis and evaluation of the educational level (character) of rural population in Poland perceived as educational advancement as well as of its environment (background). Growing importance of education in improving professional opportunities, changing educational aspirations and parents’ support as well as positive internal migration trends were emphasised. Rural regions are still lagging behind urban areas, though optimistic characteristics indicate receding stigmatisation and marginalisation of the Polish country with internal migration of young and educated individuals, including affluent ones (potential luxury goods buyers), to rural area…
How alternative food networks work in a metropolitan area? An analysis of Solidarity Purchase Groups in Northern Italy
2019
AbstractOur paper focuses on Solidarity Purchase Group (SPG) participants located in a highly urbanized area, with the aim to investigate the main motivations underlining their participation in a SPG and provide a characterization of them. To this end, we carried out a survey of 795 participants involved in 125 SPGs in the metropolitan area of Milan (Italy). Taking advantage of a questionnaire with 39 questions, we run a factor analysis and a two-step cluster analysis to identify different profiles of SPG participants. Our results show that the system of values animating metropolitan SPG practitioners does not fully conform to that traditionally attributed to an alternative food network (AF…
Remote sensing:A case for moving space data towards the public good
2008
This paper discusses whether current international and national regulation of remote sensing activities achieves a true balance between proprietary interests of producers of remote sensing data and information and the needs of the community in accessing that data and information. By subjecting remote sensing data to general copyright restrictions that are often coupled with exclusive licences, irrespective of type or use of data and/or information, the development of important secondary information markets could be negatively hampered. In the long run, over-regulating access to space data may prove counter-productive in the information age. Using examples of different modes of information d…
Indicadores de responsabilidad tributaria en las fundaciones acogidas a la Ley 49/2002. Especial referencia a las fundaciones de competencia estatal
2017
En este presente trabajo se formulan indicadores de responsabilidad tributaria de las fundaciones como mecanismo de prevención de las contingencias fiscales que pudieran recaer tanto sobre estas entidades como sobre sus patronos y mecenas. Se completa así la literatura existente centrada en los ámbitos de gestión y financiero. Paralelamente, una actuación transparente de las fundaciones exige que el grado de cumplimiento de estos indicadores, sea visible por los terceros en general y por los donantes o mecenas en particular, debiéndose dar razón de dicho cumplimiento atendiendo a los distintos destinatarios de la información a suministrar. A tal fin, y siguiendo la metodología utilizada por…
Commoning of territorial heritage and tools of participated sustainability for the production and enhancement of agro-environmental public goods
2021
AbstractThe purpose of this paper is to analyze how the commoning heritage processes find application for the production of agro-environmental public goods in contexts of high socio-economic marginality and environmental vulnerability, characterized by abandonment and from the consumption of agricultural land for food use. The purpose is to understand how these processes are able to influence, at local level, the governance processes for the implementation of environmental protection strategies. The survey made it possible to verify how the commoning processes aimed at the production of agro-environmental goods generate territorial resilience, understood as a community competence able to st…
La Educación Secundaria Superior Europea. Aspiraciones utópicas, tendencias reales y cuestiones a debate.
2001
El presente artículo pretende reflex ionar, a partir del análisis realizado sobre la educación secundaria superior en Europa, sobre la di scusión actual que se genera en tomo a este nivel educativo, en un contexto marcado por las incesantes transfomaciones y a la vez por la necesidad de recapitular ante el efecto inevitable del cambio de siglo. Para cumplir su objetivo, el artículo se divide en tres apartados, cuya conexión entre sí resulta inexcusable. En el primer apartado, de carácter introductorio, se discute sobre el papel que ha de cumplir la escuela en el momento en que se vincula al binomio educación y trabajo, tratando de romper algunos esquemas predetenninados, y a la vez de redef…
