Coastal Research

A new alien psyllid Glycaspis brimblecombei, native in Australia, was first discovered in Croatia in 2020. Its presence was also confirmed in the Botanical Garden of the Institute for Marine and Coastal Research (University of Dubrovnik) on the island of Lokrum, using DNA barcoding. Distribution and spreading of this alien species were noted as across the other continents so in Europe. The pest is considered as a threat to forestry, paper industry and could affect ornamental values of the eucalyptus species. It is important to continue with following research on this species because of the potential spreading and ascendant estimation.

Conventional Extraction

AbstractEucalyptus species have found their place in traditional medicine and pharmacological research and they have also been shown to possess a large number of phenolic compounds and antioxidants. The present study sought to implement conventional extraction to yield maximal total phenolic content (TPC), total flavonoid content (TFC), proanthocyanidins, antioxidants, and saponins from E. robusta using different solvents. The most suitable extraction solvent was further employed for extracting phytochemicals from E. saligna, E. microcorys, and E. globulus to select the Eucalyptus species with the greatest bioactive compound content. The results emphasised the efficiency of water in extracting TPC ((150.60 ± 2.47) mg of gallic acid equivalents per g), TFC ((38.83 ± 0.23) mg of rutin equivalents per g), proanthocyanidins ((5.14 ± 0.77) mg of catechin equivalents per g), and antioxidants ABTS ((525.67 ± 1.99) mg of trolox equivalents (TE) per g), DPPH ((378.61 ± 4.72) mg of TE per g); CUPRAC ((607.43 ± 6.69) mg of TE per g) from E. robusta. Moreover, the aqueous extract of E. robusta had the highest TPC, TFC and antioxidant values among the other Eucalyptus species tested. These findings highlighted the efficiency of conventional extraction in extracting natural bioactive compounds from Eucalyptus species for pharmaceutical and nutraceutical applications.

Scrub vegetation encroaches into the proximity of many monuments at Myanmar’s Bagan Cultural Heritage Site, as can be seen at many other monuments on the world. The extensiveness of scrub vegetation can interfere with the integrity of the cultural landscape when ignored by site management. The current study examined how significant the occurrence of scrub vegetation might be, quantifying the canopy coverage with relative occupancy of other components in the sacred compounds. The sacred compounds in Bagan enclose religious monuments in environments classified as farmland, monastic residences, accessways, shrub-hosting areas, and scrub vegetation. The coverage of scrub vegetation was more than a quarter of the area of sacred compounds, whereas that of shrub-hosting patches was about half. The other components occupied less than one-fifth of the area. The associated occurrence of scrub vegetation indicated the invasion of alien species from the drier hinterland to the riverside of Ayeyarwady. While such a situation reveals site management as a priority, the presence of cultivated farmland in the vicinity of monuments represented suppression of weedy growth that may later facilitate the occurrence of scrub-type plants. This study suggests cultivation as a reasonable practice for the integrity of the cultural landscape and safeguarding the monuments in Bagan.

Patella Ferruginea

Patella ferrugineais an endangered marine gastropod, distributed on the western Mediterranean coasts, whose range has progressively contracted, due to intense human exploitation. A genetic analysis was performed on two unidentified young individuals belonging to the genusPatellafound attached to the shell of an adult ofP. ferruginea, with a twofold aim: (i) to achieve their correct taxonomic attribution by means of the DNA barcoding; and (ii) to shed some light on the hypothesized larval philopatry and/or juveniles phoresis inP. ferruginea. The survey was carried out comparing the sequences of the cytochrome c oxidase subunit I (COI) Folmer region obtained for the two juveniles with those obtained for adults ofP. ferruginea, P. caerulea, P. rustica, andP. ulyssiponensis, from different sites of the western Mediterranean, by means of maximum likelihood cluster analysis and a Bayesian-based assignment test. Results obtained evidenced that: (i) COI may be used with confidence as DNA barcoding in the genusPatella; and (ii) the two juveniles studied are not conspecific: one belonged toP. ferruginea, the other toP. rustica.The latter finding raises doubts about the juvenile phoresis and about the occurrence of larval philopatry inP. ferruginea, suggesting that an extensive use of a molecular approach for a better evaluation of the recruitment features of this endangered species should be adopted.

Growing Conditions

In the 1980s, Eucalyptus macarthurii and E. nitens were planted in the colder, higher altitude areas of South Africa to meet the increased demand for pulpwood. To find possible alternatives, six site × species interaction trials were planted in 1990–1991. Based on volume performance and pulping properties, E. badjensis, E. benthamii, E. oreades, E. nobilis, E. smithii, and E. fraxinoides were identified as having good commercial potential. Although the performance of the parent crop is important, the ability to coppice is advantageous because of lower reestablishment costs. To determine this, the ability for these species to coppice was assessed at 10 months after felling at two of the trial sites with widely different growing conditions (Broadholms in Mpumalanga province and Draycott in KwaZulu-Natal province). More than 80% of the living stumps of E. benthamii, E. smithii, E. quadrangulata, E. macarthurii, E. badjensis, E. dunnii, E. cypellocarpa, E. saligna, and E. elata had coppiced at both sites. At Draycott, an exposed, dry site, both E. smithii and E. benthamii could be considered as potential alternative species to E. nitens, because besides having good volume, both species coppiced well. At Broadholms, a more protected and slightly wetter site, the significantly better volume of E. fraxinoides (which did not coppice well) when compared with the other species would mean that a substantial saving in reestablishment costs via coppice regeneration would have to be made before one could consider this method of reestablishment.

Derived Demand

Derived demand for roundwood created by the three major forest-products industries in Ontario from 1952 to 1980 was estimated from the production functions of the industries. The Cobb–Douglas function represents the lumber and the veneer and plywood industries, and the constant elasticity of substitution (CES) function represents the pulp and paper industry. In all three industries, the derived demand for roundwood is price inelastic. A theorem that the sum of partial price elasticities of derived demand when output of the final product is held constant is equal to zero has been proved. Demand by the lumber industry showed regular fluctuations throughout the 29-year period of study, while that by the other two industries rose steadily except for a few slumps.

Resumen El objetivo de este trabajo es doble. En primer lugar, estudiamos la figura y la obra del médico y naturalista Ángel Guirao Navarro al frente del Instituto Provincial de Segunda Enseñanza de Murcia. Este polifacético profesor tuvo un importante rol en el desarrollo de los espacios escolares para la enseñanza práctica de la Historia Natural, dándoles contenido con la aportación de objetos naturales recolectados por él o adquiridos por el Instituto. También analizamos los materiales de apoyo para esa enseñanza como: los libros de texto, el herbario y las láminas de pared. Por otro lado, estudiamos el espacio utilizado para la enseñanza práctica de la Botánica y la Agricultura. El papel de Ángel Guirao en el desarrollo del Jardín Botánico fue clave para que este se convirtiera en uno de los jardines educativos más completos de España con la construcción de invernaderos de cristal, umbráculos, pabellón docente y la adquisición de plantas y semillas facilitadas por el Jardín Botánico de Valencia, el Real Jardín Botánico de Madrid y el Instituto Agronómico de la Moncloa. Abstract The goal of this paper is twofold. First, we study the figure and work of the medicine doctor and naturalist Ángel Guirao Navarro, head of the Secondary School of Murcia. This versatile teacher played an important role in the development of scholar spaces for the practical teaching of Natural History by contributing with natural objects collected by him or acquired by the Secondary School of Murcia. We also analyse the pedagogical materials for this teaching such as: textbooks, herbarium and wall papers. On the other hand, we study the space used for the practical teaching of botany and agriculture. The role of Ángel Guirao in the development of the Botanical Garden was key for it to become one of the most complete educative gardens of Spain with the construction of glass greenhouses, shade structures, one teaching pavilion, as well as the acquisition of plants and seeds provided by the Botanical Garden of Valencia, the Royal Botanic Garden of Madrid and the Agronomic Institute of La Moncloa.

Drosophila lini and its two sibling species, D. ohnishii and D. ogumai, are hardly distinguishable from one another in morphology. These species are more or less reproductively isolated. The mitochondrial ND2 and COI-COII and the nuclear ITS1-ITS2 regions were sequenced to seek for the possibility of DNA barcoding and to reconstruct the phylogeny of them. The character-based approach for DNA barcoding detected some diagnostic nucleotides only for monophyletic D. ogumai, but no informative sites for the other two very closely species, D. lini and D. ohnishii, of which strains intermingled in the molecular phylogenetic trees. Thus, this study provides another case of limited applicability of DNA barcoding in species delineation, as in other cases of related Drosophila species. The molecular phylogenetic tree inferred from the concatenated sequences strongly supported the monophyly of the cluster of the three species, that is, the lini clade. We propose some hypotheses of evolutionary events in this clade.

Hydrodistillation of the fresh leaves of E.grandis×E.urophylla hybrids and pure species E.grandis, E.urophylla, E.pellita, E.camaldulensis, E. dunni, and E.saligna collected from the trees grown in Guangxi Huangmian Forest (China), afforded essential oils in yields varying from 0.24±0.15% to 5.36±0.28%, according to the species. Analysis by GC (FID) and GC/MS allowed the identification of 67 compounds, representing 82.55% to 91.03% of the total oil composition. The dominant compounds were 1,8-cineole in E.saligna, E.urophylla, E.grandis×E.urophylla, E.grandis, E.pellita and E. dunni (67.48, 57.12, 48.21, 23.64, 20.34, 20.22%), p-Cymene in E.camaldulensis,E. dunni and E.grandis(21.32, 14.74, 13.38%), α-pinene in E.grandis and E.grandis×E.urophylla (21.77, 15.55%), α-terpinene in E. dunni and E.grandis (17.96, 9.35%), α-terpineol in E.pellita and E.saligna (19.24,11.54%), respectively. Hierarchical Cluster Analysis separated the characterized essential oils into two groups, each constituting a chemotype. E.grandis×E.urophylla and E.urophylla were classified in the same group, while E.grandis in the other.
