Environmental Conditions, Air Pollutants, and Airways
2019
Air pollution is a major problem worldwide, which could be even more serious for athletes who train in urban environments. Exercise increases minute ventilation and exposure to pollutants, but the literature on the effects of air pollution in athletes is relatively scarce, with the exception of chlorine exposure in athletes of aquatic sports and air pollution secondary to ice resurfacing in athletes performing in ice arenas. Although air pollution may exert detrimental effects on athletic performance, little has been published on this topic. The largest body of information regards the impact of air pollution during urban active transport, i.e., walking and cycling in cities, due to the pote…
Hallazgo de una población de Quickella arenaria (Potiez & Michaud, 1835) (Mollusca, Gastropoda, Succineidae) en Castilla-La Mancha (España)
2017
Troballa d’una població de Quickella arenaria (Potiez & Michaud, 1835) (Mollusca, Gastropoda, Succineidae) a Castella-la Manxa (Espanya) Després de l’estudi d’un gran nombre de surgències a la província de Conca (Espanya) es comunica la troballa, per primera vegada a Castella-la Manxa, del gasteròpode succineid Quickella arenaria, poc conegut a Espanya. A més a més s’assenyalen les amenaces que suporta la població al lloc on viu i se’n proposa la conservació.
Abiotisko un biotisko faktoru ietekmes analīze veģetācijas eksperimentos ar jūras piekrastes reto un aizsargājamo augu sugām
2017
Darba mērķis bija veikt daudzfaktoru eksperimentus un aprobēt veģetācijas pētījuma metodiku jūras piekrastes reto un aizsargājamo augu sugu fizioloģiskajiem pētījumiem, lai noskaidrotu dabisko faktoru iespējamo ietekmi. Piekrastes zonas ir dinamiski mainīgas vietas, kurās sastopamas daudzas endēmas augu sugas, no kurām liela daļa ir retas un aizsargājamas. Eksperimentos izmantoja četras jūras piekrastes retās un aizsargājamās augu sugas - smiltāja neļķi (Dianthus arenarius), jūrmalas pērkonamoliņu (Anthyllis maritima), jūrmalas ceļteku (Plantago maritima) un jūrmalas āžloku (Triglochin maritimum). Augu sugas pavairoja ar sēklām vai veģetatīvi un atkarībā no sugas ekoloģijas, veica piekraste…
Decomposing issue patterns in crisis communication: the case of the lost airliner
2018
This research explores the relation between a crisis and public discussion on related issues. In organisational crisis communication, a singleissue strategy is often proposed. Such a strategy, however, may not be adequate in more complex crises where the crisis lifecycle is likely to encompass shorter lifecycles of issues that generate media attention. Decomposing the online crisis debate into a pattern of issues supports understanding of public perceptions, and hence of crisis response and communication. This is investigated through an analysis of Facebook posts prompted by the loss of Malaysia Airlines flight MH370 in 2014. The analysis shows that during the life of the crisis a variety o…

Eiropas aizsargājamās sugas Dianthus arenarius subsp. arenarius fizioloģiskā reakcija uz apbēršanu ar smiltīm un nobradāšanu
2019
Smiltāja neļķe ir Eiropas padomes direktīvas aizsargājama suga, kas sastopama piekrastes dzīvotnēs. Nobradāšana un smilšu pārpūšana ir faktori, kas ietekmē augāju kāpu joslā. Darba mērķis ir kontrolētos apstākļos noskaidrot kāda ir smilšu akumulācijas un nobradāšanas ietekme uz smiltāja neļķi un kā mainās sēklu dīgstu parādīšanos, pie dažādām substrāta akumulācijas pakāpēm. Siltumnīcas apstākļos augus izdalīja deviņos dažādos variantos, kombinējot apbēršanas un nobradāšanas faktorus. Sēklu dīgšanas pētīšanai izdalīja četros apbēršanas variantus un vienu kontroles grupu. Secināja, ka gan apbēršana ar smilti, gan nobradāšana negatīvi ietekmē auga vitalitāti un pat neliela apbēršana nepasargā …
Evaluation of Brassicaceae seedlings as trap plants for Bagrada hilaris Burmeister in Caper bush cultivations
2020
The caper bush, Capparis spinosa (Brassicales: Capparaceae), is intensively grown on Pantelleria Island (Trapani, Sicily, Sicilian channel) where it has been granted protected geographical indication (PGI) by the EU. On this island, Bagrada hilaris, a stink bug native of Asia and Africa, is the major pest of caper crops. Recent studies have shown the attraction of B. hilaris to volatiles of brassicaceous plants at the seedling stage. The objective of this study was to evaluate three cotyledon-stage seedlings of host plants, Brassica oleracea var. botrytis (cauliflower), Eruca sativa (rocket) and Brassica carinata (Abyssinian cabbage), as potential trap plants for B. hilaris. The relative pr…

The formation of dominant voice in issue arenas
2011
Abstract The aim of the present study was to map out required changes to current stakeholder thinking in public relations (PR) research and practice for a better suited model for PR professionals. The concept of issue arenas (Luoma-aho & Vos 2009) was adopted for the future direction of stakeholder thinking. Further, a central aspect of PR management on issue arenas is the division of voice – or indirect power – of different players. It was suggested that gaining a dominant voice in an issue arena would facilitate the attainment of organizational goals. Meaning was considered cental in this process. This thesis, focused, on the formation of dominant voice in issue arenas. Two research quest…
<p><strong><em>Scutellospora deformata</em></strong><strong> (Scutellosporaceae), a new species of Gigasporales f…
2021
A new species S. deformata, that occurs in six locations of marine sand dunes along the eastern Mediterranean coast of Spain is described and illustrated from spores. In the field, the species occurred in the rhizosphere of Ammophila arenaria (Poaceae), Elymus farctus (Poaceae), Otanthus maritimus (Asteraceae), and Echinophora spinosa (Apiaceae). Morphological characters related with outer, middle and inner wall of the glomerospores as well as phylogenetic analysis (partial SSU, ITS1-5.8S region and the partial LSU nrDNA) support the hypothesis that the fungus is a new species of the Scutellosporaceae.
