Although citizenship’s literacy in biodiversity is a promising way of confronting its loss, the unawareness about this topic is generalised particularly regarding plants. The latter phenomenon, named Plant Blindness (PB), not only refers to the inability to notice and identify the surrounding plants, but also to the lack of knowledge about the basics of plant biology and to the subsequent ignorance of the value of plants. Hence, the aim of this research has been to assess whether secondary students experience PB and to analyse if this phenomenon can be interrelated with their conceptualisation and attitudes towards biodiversity. For this purpose, 63 secondary students took a mixed closed- and open-ended questionnaire on different aspects of biodiversity and plant biology. The results revealed that, despite conceptualisation of biodiversity and plant literacy increased during secondary education, most students presented PB ‘symptoms’. Moreover, some of the dimensions studied were interrelated, such as comprehension of biodiversity and different aspects of plant knowledge. Therefore, these results indicate that PB has multiple branches which are not only related to plant topics sensu stricto, but also include biodiversity; which can provide novel insights into the appropriate approach to the plant blindness issue from an educational perspective.

The serious and growing impacts of invasive alien species (IAS) on the planet make it necessary to include this issue with greater determination in educational programs, with the aim of generating citizens capable of dealing with this environmental problem in a sustainable way. Likewise, the management of IAS represents a clear socio-scientific issue (SSI), which gives greater interest to its inclusion in school. At this point, future teachers play a key role, so that their knowledge, perceptions and attitudes on the subject must be evaluated. In order to deal with this objective, a questionnaire was filled out by 400 students of the degrees in early childhood education and primary education of the Universities of La Rioja (UR) and the Basque Country (UPV/EHU), Spain. Our results show that pre-service teachers do not perceive impacts of different types generated by IAS, and they show a clear lack of knowledge about transmission vectors. Likewise, they do not support various control measures, especially slaughter of invasive vertebrates, related to affective dimensions. These results highlight the need to work toward an appropriate integration of this issue at different educational levels, training students and educators, fostering favorable attitudes toward a sustainable management of IAS.

The aim of this study was to determine the flood-risk knowledge and awareness of students in their last year of baccalaureate studies. The study was conducted with three schools from the Basque Autonomous Community, which had different levels of flood-risk. In those schools there were some students who studied flood-risks in Earth and Environmental Sciences subject. Comparisons about students’ perceptions and knowledge were made among the students who lived in places exposed to different levels of flood-risk. In addition, a comparison was made to know if the students who studied Earth and Environmental Sciences in school were more aware and had more knowledge about flood-risks. Results showed that overall there was little knowledge and risk perception among the students. Moreover, the study was focused on designing an inquiry based teaching and learning sequence about flood-risk, in order to enhance risk perceptions and knowledge. There, floods are studied as part of the streams´ dynamics, where students ask questions to themselves, use digital resources, conduct small researches and critically reflect and argue about this socio-scientific issue.

Mycorrhizal inoculation of conifer roots is a key strategy to optimize establishment and performance of forest tree species under both natural and cultivated conditions and also to mitigate transplantation shock. However, despite being a common practice, inoculation in outdoor nursery conditions has been poorly studied. Here, we have evaluated effectiveness of four fungal species (Lactarius deliciosus, Lactarius quieticolor, Pisolithus arhizus, and Suillus luteus) in the production of mycorrhizal Pinus pinaster seedlings in an outdoor commercial nursery and their ability to improve seedling physiology and field performance. All inoculated seedlings showed a significant increase in growth at the end of the nursery stage and these differences remained after 3 years of growth in the field. Differences observed in the content of malondialdehyde, total chlorophyll, carotenoids, anthocyanins, and phenolic compounds from needles of mycorrhizal and control seedlings may reflect a different sensitivity to photo-oxidative damage. We conclude that ectomycorrhizal inoculation improves adaptability to changeable growing conditions of an outdoor nursery and produces a higher quality nursery stock, thereby enhancing seedling performance after planting.

The response to drought of 20 open-pollinated families from four Pinus pinaster Ait. populations covering a latitudinal cline (France, Central and Southern Spain, and Morocco) was assessed. The seedlings were cultivated in a greenhouse under controlled temperature and vapor pressure deficit for 120 days, and subjected to two watering regimes for 60 days. Different biomass partitioning variables, pre-dawn water potential, and isotopic discrimination of 13C in needles (Δ) as surrogate of long-term water use efficiency were estimated for each seedling at the end of the experiment. In response to the imposed drought, there was no change in the root biomass partitioning, but the overall Δ values decreased in response to water stress. All the families of the population from Morocco showed the highest investment in roots, regardless of the watering regime imposed. Inter-family differences within populations were also significant for most parameters as confirmed by the heritability values estimated (higher under the well-watered treatment). The studied P. pinaster populations showed different strategies of response to drought. This may represent an important mechanism by local populations in facing future climatic change. The results could be of value in forest conservation and breeding programs of maritime pine in the future.

We have investigated the effect of storage conditions (duration: 1, 8 or 15 days; temperature: 4°C or 10°C) and root coverage [bare root (BR) or soil-plugged root (PR)] on the water status, electrolyte leakage and root growth potential (number of new roots and new root length) of radiata pine (Pinus radiata D. Don) seedlings. We have also examined the effects that storage causes on plant quality and initial survival potential and their usefulness for detecting physiological damage to seedlings. We observed a gradual decrease of seedling water status and an increase in electrolyte leakage, both in root and shoot, with duration of storage, the latter indicating damage to membranes. Both storage temperature and duration influenced the ability of radiata pine seedlings to initiate and elongate new roots. The effect was more pronounced in BR than in container seedlings, suggesting that the rooting-plug medium provides protection against desiccation. The close relationship (r=0.923, P<0.05) between root growth potential and predawn xylem water potential before transplanting shows that water potential at the time of transplanting is a reliable predictor of the ability to generate new roots. Finally, we have observed a close relationship between survival and parameters such as electrolyte conductivity, post-storage water potential, new root length and root growth potential.
