Orchestrating ubiquitous learning situations about Cultural Heritage with Casual Learn mobile application

Producción CientíficaCultural Heritage learners can highly benefit from ubiquitous learning approaches that connect in-classroom activities with active on-site learning opportunities. However, teachers face the problem that the current landscape of technological support for learning Cultural Heritage mostly consists of mobile applications for informal contexts, completely decoupled from curricular activities. This paper presents the results of an exploratory-sequential mixed-methods study that focuses on the feasibility, for non-technical expert teachers, of repurposing an existing mobile application in formal Cultural Heritage ubiquitous learning situations. Such feasibility is explored from the perspective of the orchestration metaphor. More specifically, we used the “5+3 aspects orchestration framework” to understand the orchestration challenges of four ubiquitous learning situations about Cultural Heritage carried out in two secondary schools. These situations involved five teachers and 139 students who used a mobile application called Casual Learn for several weeks. The results of the study suggest that, after a brief training, teachers can design, enact, and orchestrate ubiquitous learning situations that involve both in-classroom and out-classroom activities. The teachers were able to transfer to the students most of the orchestration load of out-classroom activities. The results also showed that the flow of learning artifacts and information between in- and out-classroom activities is a critical issue that needs to be addressed by developers of ubiquitous learning technological solutions.Junta de Castilla y Leon - Fondo Europeo de Desarrollo Regional (project VA257P18)Agencia Estatal de Investigación - Fondo Europeo de Desarrollo Regional (project TIN2017-85179-C3-2-R

Defining the importance of landscape metrics for large branchiopod biodiversity and conservation: the case of the Iberian Peninsula and Balearic Islands

The deficiency in the distributional data of invertebrate taxa is one of the major impediments acting on the bias towards the low awareness of its conservation status. The present study sets a basic framework to understand the large branchiopods distribution in the Iberian Peninsula and Balearic Islands. Since the extensive surveys performed in the late 1980s, no more studies existed updating the information for the whole studied area. The present study fills the gap, gathering together all available information on large branchiopods distribution since 1995, and analysing the effect of human population density and several landscape characteristics on their distribution, taking into consideration different spatial scales (100 m, 1 km and 10 km). In overall, 28 large branchiopod taxa (17 anostracans, 7 notostracans and 4 spinicaudatans) are known to occur in the area. Approximately 30% of the sites hosted multiple species, with a maximum of 6 species. Significant positive co-occurring species pairs were found clustered together, forming 4 different associations of large branchiopod species. In general, species clustered in the same group showed similar responses to analysed landscape characteristics, usually showing a better fit at higher spatial scales.Brazilian Conselho Nacional de Desenvolvimento Cientifico e Tecnologico-CNPq [401045/2014-5]Spanish Ministry of Education, Culture and Sport [FPU014/06783]info:eu-repo/semantics/publishedVersio

Producción CientíficaThis paper presents a case study that analyzes the orchestration of a ubiquitous learning situation involving a teacher and 89 secondary-school students using Casual Learn. This case study allows us to illustrate how teachers can use Casual Learn to orchestrate ubiquitous learning situations to learn Cultural Heritage. During the case study, Casual Learn played a key role as it enabled to bridge in- and out-classroom activities across physical and virtual learning spaces.Junta de Castilla y León - Fondo Europeo de Desarrollo Regional (project VA257P18)Agencia Estatal de Investigación - Fondo Europeo de Desarrollo Regional (project TIN2017-85179-C3-2-R

Crayfish invasion facilitates dispersal of plants and invertebrates by gulls

The red swamp crayfish (Procambarus clarkii), originally from North America, is one of the world's worst aquatic invaders. It is a favoured prey item for waterbirds, but the influence of this novel predator–prey relationship on dispersal of other organisms has not previously been considered. We investigated the potential for dispersal of plants and invertebrates by migratory waterbirds feeding on alien P. clarkii in European ricefields at harvest time. In November–December of 2014–2015, we collected propagules from the outside of 13 crayfish captured as they moved out of ricefields during harvest in Doñana, south‐west Spain. We also collected excreta (N = 76 faeces, 14 pellets) of lesser‐black backed gull (Larus fuscus). We recorded diaspores from at least 11 plant species (161 seeds from 10 angiosperm taxa, and 14 charophyte oogonia) on the outside of crayfish, together with 54 eggs from eight aquatic invertebrate taxa. Adults and juveniles of at least nine microcrustaceans, including the alien ostracods Hemicypris reticulata and Ankylocythere sinuosa, were also recovered from crayfish. No intact propagules were present in the digestive system of the crayfish. Contents of regurgitated pellets confirmed P. clarkii as the main food item for gulls. Diaspores from at least 12 plant species (154 seeds from 11 angiosperm taxa, and 17 charophyte oogonia) were recovered from gull excreta, together with 129 eggs of 12 aquatic invertebrate taxa. A statoblast of the alien bryozoan Plumatella vaihiriae was found in gull faeces. Seven of the plant species are important agricultural weeds, and two are alien to Spain. Diaspores from six plant taxa were germinated, confirming viability. These propagules were from a similar set of plants and invertebrates to those found on the outside of crayfish, suggesting that propagules in gull excreta were ingested inadvertently with their crayfish prey. Ricefields constitute a major artificial aquatic habitat covering an increasing proportion of the world's land surface and typically support native or alien crayfish. Crayfish invasion can lead to novel secondary dispersal pathways for plants and invertebrates through interactions with their predators, promoting the expansion of alien and native species (including weeds) through long‐distance dispersal via migratory waterbirds and increasing connectivity of organisms between artificial and natural ecosystems. This represents a previously overlooked impact of crayfish invasion on ecosystem services. Supporting InformationPeer reviewe
