Density-dependent vole damage in silviculture and associated economic losses at a nationwide scale

2009

Voles inflict damage to silviculture by debarking or severing tree seedlings. The large-scale impacts of vole damage to silviculture, both in terms of severity and financial losses are, however, poorly known. In autumn 2005, cyclically fluctuating vole populations were at their highest in Finland for over 15 years, which led to extensive damage to silviculture during the winter 2005/06. We carried out a nationwide assessment of the incidence, spatial extent and economic value of damage and its relation to vole abundance in privately owned forests during this winter. Damage data were obtained with a questionnaire addressed to the directors of all Forest Management Associations (FMAs) operati…

Tourism marketing and local celebrations: A case study in Valencia’s Fallas

2020

El artículo pretende mostrar la necesidad de emplear estrategias de marketing turístico en la oferta de la Fiesta de las Fallas que tienen lugar en Valencia (España), declaradas Patrimonio Cultural Inmaterial de la Humanidad en 2016. Se desarrolla la teoría acerca de esta herramienta, argumentando las características y capacidades del evento y fundamentando su importancia como pieza clave en el desarrollo del turismo cultural valenciano. Los datos recogidos y las entrevistas abiertas realizadas manifiestan que la Fiesta de las Fallas debe considerarse un producto turístico y emplear estrategias que muestren la autenticidad y singularidad de Valencia como destino turístico. The article aims …

Knowledge Sharing Among Tourists via Social Media: A Comparison Between Facebook and TripAdvisor

2016

This paper examines tourists' knowledge sharing behavior in social media. Based on social capital theory, we aim to examine the effects of three dimensions of social capital—structural (social interaction ties), cognitive (shared vision) and relational (trust)—for two different types of social media: Facebook and TripAdvisor. We propose a structural model that connects an antecedent (homophily) and a consequence (knowledge sharing through posting) of these main dimensions of social capital. An online survey is conducted with 1200 Spanish consumers. Based on the full sample, our structural equation modeling supports most of the hypothesized paths, while trust does not affect either social in…

Ethics in biodiversity conservation : The meaning and importance of pluralism

2022

Addressing the global extent of the current biodiversity crisis requires engaging with the existence of multiple equally legitimate values, but also with diverse ethical perspectives underpinning conceptions of right and wrong actions. However, western monist positions have mostly explicitly or implicitly directed conservation strategies by defining the space of legitimate arguments, overlooking solutions that do not fit neatly the chosen approaches. As ignoring diverse ethical positions leads to injustices and reduces the potential of conserving biodiversity, there is a need to recognise and navigate the ethical landscape. Ethical pluralism may provide opportunities to do so. However, the …

The first few months of life is the most vulnerable period for fish and their optimal hatching time with zooplankton prey is favored by natural selection. Traditionally, however, prey abundance (i.e., zooplankton density) has been considered important, whereas prey nutritional composition has been largely neglected in natural settings. High-quality zooplankton, rich in both essential amino acids (EAAs) and fatty acids (FAs), are required as starting prey to initiate development and fast juvenile growth. Prey quality is dependent on environmental conditions, and, for example, eutrophication and browning are two major factors defining primary producer community structures that will directly d…

Soil feedback does not explain mowing effects on vegetation structure in a semi-natural grassland

2009

Due to its ability to create aboveground conditions that favour plant diversity, mowing is often used to preserve the high conservation value of semi-natural species-rich grasslands. However, mowing can also affect belowground conditions. By decreasing plant carbon supply to soil, mowing can suppress the activity of soil decomposers, diminish plant nutrient availability and thus create a feedback on plant growth. In this study, we first documented the effects of three-year mowing on plant community structure in a species-rich grassland. We found that mowing decreased the total areal cover of woody plants and increased the total cover of leguminous forbs. At the species level, mowing further…

The impact of urban development on aquifers in large coastal cities of West Africa: Present status and future challenges

2018

Abstract This paper investigates the coastal cities of Abidjan, Cotonou, Lagos and Douala in West Africa. Published data on these areas were aggregated in order to compare the urban development of some African huge cities and assess their impacts on groundwater. Those urban centers have experienced an exponential demographic expansion since the 1950s, with increased population densities and a geographical coverage expansion as well. The Continental Terminal aquifer, major groundwater resource taped in this region by the national water companies and local populations, shows a continuous downward trend in piezometric levels. Concerning water quality, the evolution up to the current state (sal…
