Sustainable Ecotourism through Cutting-Edge Technologies

Tourism is a phenomenon that dates back to ancient times. Ancient Greek philosophers recognised, adopted, and promoted the concept of rest-based tourism. Ecotourism is a particular type of tourism that connects with activities that take place in nature, without harming it, along with the herbal and animal wealth. According to estimates, the global ecotourism industry is currently booming due to various reasons, and it is becoming an important factor of sustainable regional development. This article presents the vision, work, and outcomes of project AdVENt, a project focusing natively in sustainable ecotourism through natural science and technological innovation. AdVENt’s study area includes the National Parks of Oiti (or Oeta) and Parnassus in Central Greece, where there is a remarkable native flora with a high endemism rate integrated with areas of cultural value and national and European hiking routes and paths of varying difficulty.

EFFECTS OF GLYPHOSATE ON GERMINATION AND PHOTOSYNTHESIS IN Prosopis alba G.: A BIOCHEMICAL APPROACH

In recent decades, the phytogeographic region of the Western Chaco has been subjected to heavy deforestation. The native forest was gradually replaced by agricultural crops using high doses of herbicides. Glyphosate is the most widely used herbicide, and its impact on the surrounding native flora is unknown. The aim of this work was to determine the effect of glyphosate on the germination of Prosopis alba seeds and the photosynthesis of seedlings. Seeds were placed between paper towels, moistened with solutions of 0, 10, 20, 20, 30 and 40 mg a.i. glyphosate l-1, in a growth chamber at 25 oC and a 12 h photoperiod. The percentage of germinated seeds and the mean germination time were calculated. The respiratory rate was measured in these seeds, and the activity of complexes I and III of the respiratory chain was quantified. The shikimate concentration and antioxidant response of the seeds were also quantified. Chlorophyll a fluorescence emission variables were measured in the cotyledons. It was concluded that glyphosate inhibits germination in P. alba seeds and decreases the speed of the process. This effect can partly be explained by inhibition of respiration, mainly at the level of complex III of the mitochondrial electron transport chain. It is also due to oxidative stress produced by the herbicide, since the antioxidant response of the seeds fails to compensate for the high production of reactive oxygen species. Glyphosate inhibits the photochemical stage of photosynthesis on P. alba cotyledons.

Plants of the Siberian Flora exposition of the N.V. Tsitsin Main Botanical Garden RAS, listed in the Red Book of Russia

The strategy and key principles of setting up natural flora exhibits were conceptualized by the founder and first manager of the Flora Department, Prof. M. Kultiasov based on the ecological and historical method of plant introduction. The Siberian flora exhibit was among the first created by the Laboratory. Nowadays it comprises 111 species (131 specimens) belonging to 68 genera of 39 families of plants. This collection includes 5 species of plants listed in the Red Data Book of Russia, namely Anemonastrum baicalense (Turcz.) Mosyakin, Cotoneaster acutifolius Turcz., Erythronium sibiricum (Fisch. & C.A. Mey.) Krylov, Paeonia tenuifolia L., Leuzea carthamoides (Willd.) DC. By category of rareness, out of five these species, one (Paeonia tenuifolia) belongs to Category Two (threatened) and four species (Anemonastrum baicalense, Cotoneaster acutifolius, Erythronium sibiricum, Leuzea carthamoides) belong to Category Three (rare). By category of integrated introductory resistance, all the species introduced may be categorized as ‘resistant in a controlled environment’.

Pollinator-friendly flora in rangelands following control of cheatgrass (Bromus tectorum): a case study

Invasive winter annual grasses, such as cheatgrass (Bromus tectorum L.) are considered serious threats to regional biodiversity. Pollinator populations that depend on the native flora are likely to be negatively impacted as these native species may be displaced by the invasive grass species. Colonization by cheatgrass is also predicted to increase risk of wildfires, as dead plant parts provide fuel in the already dry and arid regions of the western United States. Biocontrol, grazing, prescribed burning, or use of broad-spectrum nonselective herbicides have been suggested as possible means to control B. tectorum. Efficient control may facilitate regrowth of native flora that could in turn support other ecosystem functions. Reporting our findings as a case study, we describe here the results of the application of a preemergent herbicide, indaziflam, that limits germination of B. tectorum seeds. Herbicide was applied to the study locations during the months of December 2016, January 2017, and February 2017. The data reported here on the diversity of flowering plants were collected between May through September 2018. Herbicide-treated plots showed an increase in diversity and abundance of flowering plants compared to the untreated control within two seasons after cheatgrass control was implemented, suggesting that effective reduction of the population of the invasive annual cheatgrass may help facilitate the growth of native forbs. Further studies are necessary to understand mechanisms that facilitate reestablishment of native flowering species, the long-term consequences of reducing invasive annual grasses and to document any residual effects of the herbicide on ground-nesting pollinators.

Darwin’s naturalization conundrum disentangled: the role of phylogenetic relatedness depends on the invasion stages

Darwin’s naturalization hypothesis predicts successful invaders to be distantly related to native species, whereas his pre-adaptation hypothesis predicts the opposite. It has been suggested that depending on the invasion stage (i.e. introduction, naturalization, and invasiveness), both hypotheses, now known as Darwin’s naturalization conundrum, could hold true. We tested this by analysing whether the likelihood of introduction for cultivation as well as subsequent stages of naturalization and invasion of species alien to Southern Africa are correlated with their phylogenetic distance to the native flora of this region. While species were more likely to be introduced for cultivation if they are distantly related to the native flora, the probability of subsequent naturalization was higher for species closely related to the native flora. Furthermore, the probability of becoming invasive was higher for naturalized species distantly related to the native flora. These results were consistent across three different metrics of phylogenetic distance. Our study reveals that the relationship between phylogenetic distance to the native flora and success of an alien species depends on the invasion stage.

The Urewera Notebook: Scholarly edition

<p>This thesis is a scholarly edition of Katherine Mansfield’s Urewera Notebook. The General Introduction summarises the purpose to which the notebook has been put by previous editors and biographers, as evidence for Mansfield’s happiness or unhappiness in New Zealand throughout 1906-8. It then offers an overview of the historical context in which the notebook was written, in order to demonstrate the social complexity and geographical diversity of the terrain that Mansfield covered during her 1907 camping holiday. This is followed by an analysis of Mansfield’s attitudes towards colonials, Maori and the New Zealand landscape. Mansfield’s notebook is permeated by a sense of disdain for colonials, especially when encountered as tourists, but also a fascination with ‘back-block ’settlers and a sense of camaraderie with her travelling companions. Mansfield repeatedly romanticised Maori as a noble ‘dying race’ with a mythic past, but was also insightfully observant of the predicament of Maori incontemporary colonial society. Her persistent references to European flora, fauna and ‘high culture’, and her delight in conventionally picturesque English gardens, reveal a certain disconnect from the New Zealand landscape, yet occasional vivid depictionsof the country hint at a developing facility for evokingNew Zealand through literature.In the Textual Introduction I discuss the approaches of the three prior editors of the notebook: John Middleton Murry polished, and selectively reproduced, the Urewera Notebook, to depict Mansfield as an eloquent diarist; Ian A. Gordon rearranged his transcription and couched it within an historical commentary which was interspersed with subjective observation, to argue that Mansfield was an innate short story writer invigorated by her homeland. Margaret Scott was a technically faithful transcriber who providedaccuracy at the level of sentence structure but whoseminimal scholarly apparatus has madeher edition of the notebook difficult to navigate,and has obscured what Mansfield wrote. I have re-transcribed the notebook, deciphering many words and phrases differently from prior editors. The Editorial Procedures are intended as an improvement on the editorial methods of prior editors.The transcription itself is supported by a collation of all significant variant readings of prior editions. Arunning commentary describesthe notebook’s physical composition, identifies colonial and Maori people mentioned in the text, and explains ambiguous historical and literary allusions, native flora and fauna,and expressions in Te Reo Maori. The Itinerary uses historical documents to provide a factually accurate description of the route that Mansfield followed, and revises the itinerary suggested by Gordon in 1978. A biographical register explains the social background of the camping party. This thesis is based on fresh archival research of primary history material in the Alexander Turnbull Library, legal land ownership documents at Archives New Zealand, historical newspapersand information from discussions with Warbrick and Bird family descendants.A map sourced from the Turnbull Cartography Collection shows contemporary features and settlements, with the route of the camping party superimposed. Facsimiles of pages from the notebook are included to illustrate Mansfield’s handwriting and idiosyncratic entries.

Quantifying the Invasive Secondary Metabolome

Invasive plants drive ecosystem degradation through developing aggressive phenotypes that can outcompete native flora. Several hypotheses explain this, like the Evolution of Increased Competitive Ability hypothesis and the Novel Weapons Hypothesis, but none have been proven conclusively. Changes in plant metabolites are critical to these hypotheses, but complete invasive secondary metabolomes have not been quantified. Here, statistical and unsupervised machine-learning approaches were used to analyse chemotype-to-phenotype relationships in invasive and non-invasive populations in species Ageratum conyzoides, Lantana camara, Melaleuca quinquenervia and Psidium cattleainum and on a family level analysing Asteraceae, Myrtaceae and Verbenaceae. Invasive metabolomes evolved according to the EICA and NWH, involving optimisation of aggressive strategies present in native populations and local adaptation.Abstract Figure

Sand Dune Restoration in New Zealand: Methods, Motives, and Monitoring

<p>Sand dunes are critically endangered ecosystems, supporting a wide variety of specialist native flora and fauna. They have declined significantly in the past century, due to coastal development, exotic invasions, and stabilization using marram grass (Ammophilia arenaria). An increasing number of restoration groups have carried out small scale rehabilitations of using native sand binding plants spinifex (Spinifex sericeus) and pingao (Desmoschoenus spiralis). However like many other restoration ventures, efforts are not formally monitored, despite the potential for conservation of species in decline. This thesis seeks to investigate the social and ecological aspects of sand dune restoration in New Zealand. Firstly, the status of restoration in New Zealand was examined using web based surveys of dune restoration groups, identifying motivations, methods, and the use of monitoring in the restoration process. Secondly, the ecology of restored and marram dominated sand dunes was assessed. Vegetation surveys were conducted using transects of the width and length of dunes, measuring community composition. Invertebrates were caught using pitfall traps and sweep netting, sorted to order, and spiders, beetles and ants identified down to Recognizable Taxonomic Units (RTUs) or species where possible. Lizards were caught in pitfall traps, and tracking tunnels tracked the presence of small mammals in the dunes. Analysis of each variable involved the comparison of biodiversity data between restored and marram dominated dunes, at six sites across the Wellington region. The survey of dune restoration practitioners confirmed that restoration was generally based on the motivation of erosion protection and foreshore stabilization, however an increasing number of groups were interested in the conservation of flora. Conservation of fauna was a priority for only one of the respondents. Informal monitoring of restoration attempts was carried out by the majority of groups, but specific biodiversity monitoring or monitoring using systematic scientific methods was carried by only a small proportion of groups. Re-vegetation of dunes commonly used a small suite of native sand binding species mostly pingao and spinifex. Species in decline such as sand tussock (Austrofestuca littoralis) and sand daphne (Pimelia arenaria) were only planted at a small proportion of sites. Restoration of dune ecosystems has the potential to not only enhance erosion protection and sand stabilization mechanisms, but to benefit native flora and fauna endemic to sand dunes. Identifying biological change and carrying out biodiversity monitoring may be beneficial in maximizing the ecological effectiveness of restoration attempts. Marram dunes contained higher foliage cover, vegetation height and vegetation species diversity than restored dunes. Abundance and diversity of beetle, spider, and ant families were higher in marram dominated dunes. Estimated population size of common skink (O. nigraplantare polychroma) and mouse population density was also higher in marram dunes. These results were positively correlated with the percentage of vegetation foliage cover and vegetation species diversity, suggesting that the habitat conditions created by marram grass were favored by fauna. These results suggest that for maximum biodiversity gains, future dune restoration attempts should increase vegetation cover, and include a wider range of plant species. Species in decline known to be important for fauna, such as pohuehue (Muehlenbeckia spp.), sand pimelia, and sand coprosma (Coprosma acerosa) should also be included for reciprocal benefits for conservation of flora and fauna. Marram grass could also be incorporated into restoration, as its mass removal may have considerable consequences for fauna using it as a refuge, and it appears to provide desirable habitat for fauna.</p>
