Data from: The importance of phytoplankton biomolecule availability for secondary production
2018
The growth and reproduction of animals is affected by their access to resources. In aquatic ecosystems, the availability of essential biomolecules for filter-feeding zooplankton depends greatly on phytoplankton. Here, we analyzed the biochemical composition, i.e., the fatty acid, sterol and amino acid profiles and concentrations as well as protein, carbon, nitrogen, and phosphorus content of 17 phytoplankton monocultures representing the seven most abundant phytoplankton classes in boreal and sub-arctic lakes. To examine how the differences in the biochemical composition between phytoplankton classes affect their nutritional quality for consumers, we assessed the performance of Daphnia, on …
Eutrophication reduces the nutritional value of phytoplankton in boreal lakes
2019
Eutrophication (as an increase in total phosphorus [TP]) increases harmful algal blooms and reduces the proportion of high-quality phytoplankton in seston and the content of ω-3 long-chain polyunsaturated fatty acids (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) in fish. However, it is not well-known how eutrophication affects the overall nutritional value of phytoplankton. Therefore, we studied the impact of eutrophication on the production (as concentration; μg L−1) and content (μg mg C−1) of amino acids, EPA, DHA, and sterols, i.e., the nutritional value of phytoplankton in 107 boreal lakes. The lakes were categorized in seven TP concentration categories ranging from ultra…
A land of mystical beauty, living wonder and unrivalled adventure : representation of New Zealand through adventure tourism websites
2009
Matkailu on yksi suurimmista elinkeinoista maailmassa, ja se on kasvanut huomattavalla vauhdilla viimeisten vuosikymmenten aikana. Myös Uudessa-Seelannissa matkailu on yksi maan tärkeimmistä elinkeinoaloista ja työllistäjistä. Uudesta-Seelannista löytyy useita erilaisiin aktiviteetteihin erikoistuneita matkailuyrityksiä. Seikkailumatkailulla on merkittävä rooli matkailussa, esimerkiksi benji-hypystä on tullut yksi maan matkailuikoneista. Tässä tutkimuksessa keskiössä oli seikkailumatkailun rooli Uuden- Seelannin matkailullisen imagon luomisessa. Internet tarjoaa nykypäivänä tärkeän markkinointikanavan, erityisesti matkailuyrityksille. Matkailuesitteiden määrä ja merkitys on vähentynyt huom…
How hotel websites may discursively adjust to customer preferences using online criticism
2019
This paper explores discursive ways in which hotels may improve their own websites using online criticism to adjust to customer preferences. To this end, a combined method was used, consisting of a netnographic approach (Kozinet, 2010; Mkono, 2011, 2012) together with an interpersonal discourse framework (Hyland, 2008) applied to e-tourism genres (Suau-Jiménez, 2012, 2016). Four hotel websites, together with 200 corresponding negative reviews from TripAdvisor, were diachronically analyzed to identify common topics. Attitudinals were sough, being the core markers of online critiques, as well as boosters, acting as enhancing markers in hotel websites and paralleling criticized topics. Results…
The Role of Reputation on Trust and Loyalty : A Cross-Cultural Analysis of Tablet E-Tailing
2018
The purpose of this article is to empirically examine the role of online retailer's website reputation on tablet commerce and to compare the trust arbitration between reputation and loyalty in two cultures - Finland and Nigeria. Data was collected from Finland and Nigeria, using purposive and snowball sampling methods. This article uses Structural Equation Modelling and mediation analysis. The results reveal that the reputation of online retailer's website is not a direct determinant of loyalty for online shopping while trust colligates with ease of use. The effect of an online retailer's website reputation is stronger in Nigeria than in Finland and trust is a strong predictor of ease of us…
"Experience the real New Zealand - Maori culture as it is today" : representations of New Zealand and Maoris in Maori tourism websites
2012
Matkailu on maailmanlaajuisesti merkittävä ja kasvava ala. Uudessa-Seelannissa matkailulla on ollut jo pitkään merkittävä vaikutus talouteen ja koko yhteiskuntaan. Maorit ovat Uuden-Seelannin alkuperäiskansa ja vähemmistökulttuuri, sillä heitä on noin 15 prosenttia maan väestöstä. Tähän vähemmistöasemaan liittyen onkin mielenkiintoista tutkia minkälaisia representaatioita he luovat itse omasta kulttuuristaan. Matkailuun liittyy vahvasti mielikuvien luominen, sillä useimmat kulttuureihin liittyvistä matkailutuotteista perustuvat elämysten tarjoamiseen konkreettisten tuotteiden sijaan. Nämä mielikuvat ja representaatiot ovatkin tutkielman keskiössä. Tämän tutkielman tavoitteena on selvittää, …
Quelles stratégies pour les musées sur internet ? Entre " click and mortar " et " mortar and click "
2011
Many companies now use the Internet as part of a click & mortar strategy. This strategy is also used in the museum field, but its consequences have not been evaluated yet. A quantitative study carried out on a sample of 388 visitors, at the Bibracte Museum (France), indicates that the quality of an internet website, as well as the satisfaction and trust experienced by Internet users when browsing, have direct positive influence on word-of mouth and the actual museum visit. It seems therefore appropriate to integrate the internet website to the whole management of cultural and artistic activities, without forgetting to take into account the specificities of this particular field.
COVID-19: Relationship and Impact on Breastfeeding-A Systematic Review.
2021
COVID-19 is an infectious disease caused by the SARS-CoV-2 virus that was declared a Public Health Emergency of International Concern by the World Health Organization (WHO). One major problem faced is whether breastfeeding by mothers infected with the virus is safe. The objective of this work is to study the impact that the SARS-CoV-2 virus can have on breastfeeding, and whether the virus or antibodies can be transmitted from mother to child through milk. We carried out a systematic review of studies focusing on the impact of SARS-CoV-2 on breastfeeding by mothers infected with the virus. The bibliographic search was done through Medline (Pubmed), MedlinePlus and Google Scholar. From 292 re…
EVOLUZIONE DELLA LAGUNA DI TONNARELLA (MAZARA DEL VALLO, TRAPANI) E SUO ATTUALE VALORE ORNITOLOGICO
2016
Temporal changing of Tonnarella lagoon (Mazara del Vallo, Trapani) and its current ornithological value. Aims of this work were to highlight the importance of a small and artificial recently formed wetland area, that presents different interesting ornithological peculiarities. The Tonnarella lagoon is a breeding site of Little Tern Sternula albifrons and Kentish Plover Charadrius alexandrinus, both classified as “endangered” species in 2011 by the Red List of breeding birds in Italy; the site is considered of “national importance“ for Kentish Plover and “recorded site“ for the Sandwich Tern Sterna sandvicensis, due to the consistency of its wintering populations. Besides, the ornithological…
Benthic‐pelagic coupling and trophic relationships in northern Baltic Sea food webs
2020
Understanding marine ecosystem structure and functioning is crucial in supporting sustainable management of natural resources and monitoring the health of marine ecosystems. The current study utilized stable isotope (SI) mixing models and trophic position models to examine energy flow, trophic relationships, and benthic‐pelagic coupling between food web components. Roughly 1900 samples from different trophic levels in the food web, collected during 2001–2010 from four northern and central sub‐basins of the Baltic Sea, were analyzed for SI ratios of carbon and nitrogen. Trophic structure of the food webs among the sub‐basins was consistent, but there were differences between the proportions …
