TRY plant trait database - enhanced coverage and open access

Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Stakeholder perspectives on ecosystem service supply and ecosystem service demand bundles

Recent developments in Ecosystem Service (ES) research show a growing interest in the concept of ES bundles for informing the effective management of landscapes. While the supply of ES bundles was biophysically assessed, there has been little research about the perception of ES bundles, neither in terms of their supply, nor of their demand. This research investigates how various stakeholders perceive the delivery of ES supply bundles across different landscapes and how this differs from the ES demand bundles they request. A questionnaire survey (n = 858) was carried out on the basis of landscape photographs with local farmers, local inhabitants, and visitors in the region of South Tyrol in the Central Alps. The results show that the different stakeholder groups identify identical ES supply bundles (i.e. experiential service, life maintenance service, agroservice bundle) and associate each with a similar set of landscape types. Stakeholders, however, differ in terms of their expressed demand for ES bundles. These findings suggest that stakeholders experience different (spatial) mismatches between the supply and demand of ES, potentially leading to stakeholder conflicts in landscape management. This study concludes by discussing these potential conflicts across different landscapes and in the context of future land use and management decisions

Biodiversitätsmonitoring im Südtiroler Kräuteranbau = Biodiversity surveys in medicinal and aromatic plant fields in South Tyrol

Medicinal and aromatic plants in mountain regions such as South Tyrol are cultivated on small-scale farms, which are characterized by a high diversity of cultivated crop species grown on a relatively small area. This small-scale cultivation of medicinal and aromatic plants suggests that MAP fields are of high ecological value. However, research on this topic is generally lacking. In this study flower-visiting arthropods were recorded with pan traps in three herb fields during three survey events conducted in 2021. Our results indicate that medicinal and aromatic plant fields are valuable habitats for several taxa. In total 12.570 individuals were collected. Wild bees were particularly species-rich, accounting for 10 % of the regional wild bee species pool. Next to beneficial arthropods, potential pests, such as aphids were also highly abundant. However, natural enemies possibly counteracting pests were also numerous. Overall, we conclude that medicinal and aromatic plant cultivation may act as resource-rich oases for several arthropod groups, thereby promoting biodiversity also on a broader scale.Der Anbau von Arznei- und Gewürzpflanzen zeichnet sich in der Regel durch vielfältige Anbaukulturen auf relativ kleinen Flächen aus. Dies gilt insbesondere für Südtirol, wo diese Kulturen hauptsächlich von kleinen Betrieben im Berggebiet angebaut werden. Dieser kleinflächige Anbau von Arznei- und Gewürzpflanzen lässt vermuten, dass die Betriebe einen hohen ökologischen Wert haben. Es gibt wenige Studien zur Erfassung der Biodiversität im Anbau von Arznei- und Gewürzpflanzen. Daher wurden in dieser Arbeit Kräuteranbau-Betriebe als Lebensraum für blütenbesuchende Arthropoden untersucht. An drei Untersuchungsstandorten wurden im Jahr 2021 jeweils an drei Terminen Farbschalen zur Sammlung von Arthropoden verwendet. Kräuteranbau-Betriebe stellten sich als ein wertvoller Lebensraum für verschiedene Arthropoden heraus. Insgesamt wurden 12.570 Individuen mit den Farbschalen gesammelt. Insbesondere Wildbienen waren mit 10 % des regionalen Artenpools sehr artenreich. Auch potenzielle Schädlinge, wie zum Beispiel Blattläuse, waren sehr häufig anzutreffen, wobei natürliche Feinde, wie zum Beispiel Parasitoide, ebenfalls zahlreich vertreten waren. Insgesamt können Kräuteranbaubetriebe als strukturreiche Oasen für Arthropoden fungieren und sich somit auf einer breiteren Skala positiv auf die Biodiversität auswirken

Methods for evaluating crown area profiles of forest stands

Canopy architectures of five structurally complex forest stands and three structurally simple forest stands in southwest Oregon and the Willamette Valley, Oregon, were evaluated and quantified through crown area profiles. Mixed conifer and mixed conifer-hardwood stands across a range of sites were sampled for crown widths and heights. Crown width and shape equations were derived and used to quantify the stand crown area at incremental heights above the forest floor. Crown area profiles describe the spatial arrangement of aboveground forest vegetation and the total pore spaces between crowns. Plot by plot profiles were combined to produce vertical and horizontal displays of the stand crown area distribution. In complex stands, the forest space was moderately occupied by crowns from the forest floor up to heights over 30 m, producing uniform distributions of between-crown porosity. The structurally complex stands had between-crown porosity values of 70% to 90% for more than 23 vertical metres of canopy, and they had total between-crown porosities of 86% to 91%. The structurally simple stands had between-crown porosity values of 70% to 90% for less than 8 vertical metres of canopy, and they had total between-crown porosities of 69% to 85%. Variances in crown area indicate that variation in horizontal crown area (within heights) was larger in complex stands than in simple stands, but vertical crown areas (between heights) varied less in complex stands. The study provides a basis for discriminating between canopy architectures and for quantifying the porosity of forest canopies

Biodiversity surveys in medicinal and aromatic plant fields

Medicinal and aromatic plants (MAPs) in mountain regions are cultivated on smallscale farms, which are characterized by a great diversity of MAPs grown on a relatively small area and by a high degree of habitat complexity. Non-crop elements (e.g., drystone walls, hedges, etc.) are widely present in these cultivated areas and, together with high plant diversity, may provide ideal foraging and breeding habitats for several animal groups. Here we surveyed small-scale MAP fields from a multi-taxonomic perspective considering flower-visiting arthropods, butterflies, grasshoppers, ground-dwelling arthropods, birds, and bats. A total of three MAP fields were surveyed, however not every taxon was surveyed in each MAP field. Pan traps were used in all MAP fields to assess flower-visiting arthropods with special attention to wild bees. In one of the selected fields a Malaise trap was used, and the other taxa were surveyed according to the protocol of the Biodiversity Monitoring South Tyrol. An exception was the bird surveys, which were conducted in two MAP fields. Our results indicate MAP fields to be a valuable habitat for several taxa, especially wild bees, as reflected in the positive correlation of wild bee species richness and flower coverage. Next to beneficial arthropods, potential pests such as aphids were also highly abundant. However, natural enemies (e.g., hymenopteran parasitoids, ground-dwelling predators, etc.) were also numerous and possibly counteracted pests. The butterfly and grasshopper fauna were represented by common and generalist species, while the observed vertebrate communities were relatively diverse in their habitat requirements, most likely using MAP fields for foraging. Overall, we conclude that MAP cultivation sites may act as resourcerich oases for several animal groups, thereby also promoting biodiversity on a broader scal

Meadow orchards as a good practice example for improving biodiversity in intensive apple orchards

Changes in agricultural land use and management are largely responsible for the current global biodiversity crisis. Addressing this crisis necessitates a change in management practices that are considered to limit biodiversity. Comparing intensive land-use forms with their extensive and traditional counterparts can help define good practice example for integrated conservation. We compare remnants of traditional meadow orchards with intensively managed apple orchards in a mountain region by investigating the multi-taxonomic diversity of seven groups (including vascular plants, wild bees, diurnal butterflies, orthopterans, spiders, birds, and bats) and macro-invertebrates inhabiting four habitat strata (soil, ground-dwelling, herb, and tree layer). Each group and stratum was sampled with a target sampling method. We found a consistent trend of higher abundance, diversity, and presence of threatened species in meadow orchards compared to apple orchards. Specifically, wild bees, butterflies, orthopterans, and birds showed significantly lower diversity in apple orchards across different diversity indices. Furthermore, multi-taxonomic indices of all taxa and most habitat strata followed the same trend, supporting the conclusion that these findings are applicable to the entire orchard ecosystem. We conclude that traditional agroforestry systems, such as meadow orchards, could represent a well-suited good-practice example for integrated biodiversity conservation in the agricultural landscape. Finally, we emphasize the importance of maintaining traditional management practices through effective conservation measures such as subsidies as part of agri-environmental scheme

Lymphadenopathy after BCG vaccination in a child with chronic granulomatous disease

We report a 15-month-old boy who developed an ulcer in the left axillary fold following bacillus Calmette-Guerin vaccination. Subsequent immunologic and genetic studies led to the diagnosis of chronic granulomatous disease. His mother had "lupus-like" lesions, described in some carriers of this disease, that were thus related to her son's diagnosis. Although in healthy subjects this vaccination is usually harmless, in instances of impaired immunity it may cause adverse reactions. When a vaccine-related complication occurs, an underlying immunodeficiency should be sough

Rituximab in refractory Vogt–Koyanagi–Harada disease

IntroductionVogt–Koyanagi–Harada (VKH) prognosis depends on early recognition and treatment; chronic disease may be developed when either delayed or inadequate treatment is performed, whereas other cases despite correct treatment are refractory to different drugs and also become chronic. We report a case of refractory VKH controlled with rituximab treatment.Case reportA 41-year-old female with painful visual loss and headache was examined. (VA 0.4 in RE and hand movements (HM) in LE). Retinal examination demonstrated multiple serous retinal detachments in both eyes. High-dose oral steroids were started, followed by progressive tapering of prednisone. New acute anterior and posterior relapses were achieved, and other immunommodulators were progressively added—new high-dose steroid treatment, adalimumab, cyclosporine, and methotrexate—but patient had new anterior and posterior recurrences associated with tinnitus and headache. Thus, an infusion of 1 g of rituximab was administered after 15 months follow-up; the VA was 0.2 in RE and counting fingers in LE. Three additional doses of 1 g each were administered 1, 6, and 16 months later. We have achieved a final VA after 34 months follow-up of 0.2 in RE and HM in LE, with definitive control of inflammation, without acute relapses since rituximab was administered.ConclusionAfter searching PubMed/Medline, this is the first report of VKH disease treated with rituximab. Additional studies are warranted to confirm the efficacy of this new approach for inflammatory control in refractory cases of VKH disease

Antifibrotic effects of tocotrienols on human Tenon's fibroblasts

Antifibrotic effects of α- (40, 60, 80, 100, and 120 μM), γ- (10, 20, 30, and 40 μM) and δ-tocotrienol (10, 20, 30, and 40 μM) on hTf cultures were evaluated by performing proliferation, migration and collagen synthesis assays. Whereas for vitamin E the exposure time was set to 7 days to mimic subconjunctival application, cultures were exposed only 5 min to mitomycin C 100 μg/ml to mimic intraoperative administration. Cell morphology (phase contrast microscopy) as an assessment for cytotoxicity and cell density by measuring DNA content in a fluorometric assay to determine proliferation inhibition was performed on day 0, 4, and 7. Migration ability and collagen synthesis of fibroblasts were measured. Results All tested tocotrienol isoforms were able to significantly inhibit hTf proliferation in a dose-dependent manner (maximal inhibitory effect without relevant morphological changes at day 4 for α-tocotrienol 80 μM with 36.7% and at day 7 for α-tocotrienol 80 μM with 42.6% compared to control). Degenerative cell changes were observed in cultures with concentrations above 80 μM for α- and above 30 μM for γ- and δ-tocotrienol. The highest collagen synthesis inhibition has been found with 80 µM α-tocotrienol (62.4%) and no significant inhibition for mitomycin C (2.5%). Migration ability was significantly reduced in cultures exposed to 80 µM α- and 30 µM γ-tocotrienol (inhibition of 82.2% and 79.5%, respectively, compared to control) and also after mitomycin C treatment (60.0%). Complete growth inhibition without significant degenerative cell changes could only be achieved with mitomycin C. Conclusion In vitro, all tested tocotrienol isoforms were able to inhibit proliferation, migration and collagen synthesis of human Tenon’s fibroblasts and therefore may have the potential as an anti-scarring agent in filtrating glaucoma surge
