Floral expression and pollen germination ability in productive mountain papaya ( Vasconcellea pubescens A.DC.) orchards

Mountain papaya ( Vasconcellea pubescens A.DC.) is described as trioecious in the centers of origin of Ecuador, Colombia, and Peru. However, under cultivation conditions in La Serena (30° S, 70° W), Chile, it is found to be dioecious and monoecious. The objective was to learn about the variations in floral expression of mountain papaya. Flowers from monoecious and dioecious plants were therefore identified and quantified during two seasons. In vitro pollen germination ability was also evaluated based on the factors of site, season, and plant sex. Monoecious plant inflorescences are polygamous; female and male flowers are observed, as well as bisexual flowers that are usually deformed. This condition allows them to be classified as an ambisexual plant. The existence of flowers of different sexes appears to depend on the season; the female dioecious plant is maintained as such, independently of climatic conditions. Pollen from male flowers, from both ambisexual and male plants, germinates 75% in summer, while germination decreases to 56% in spring (P ≤ 0.05). Flowering of female plants coincides with the permanent occurrence of male flowers in ambisexual plants, which ensures pollination without the need for male plants as pollinators in orchards. Based on this information, some management practices and possible lines of research about this species are proposed.

Este es un estudio descriptivo, en el cual se analizaron elementos culturales y marcas coloniales y anticoloniales en la traducci?n de ingl?s a espa?ol de la obra teatral ?Dream on Monkey Mountain? [Sue?o en la Monta?a del Mono] de Derek Walcott. Para llevarlo a cabo se utiliz? el m?todo cualitativo, aunque varios datos son presentados de forma cuantitativa. Parte de la informaci?n fue recogida a trav?s de observaci?n participante en los ensayos de los estudiantes de Arte Dram?tico de la Escuela de Artes Integradas de la Universidad del Valle (Cali, Colombia). Otros datos fueron obtenidos a partir del texto objeto de la traducci?n y la traducci?n misma. En cuanto al proceso de traducci?n, ?ste se sirvi? del m?todo filol?gico o traducci?n cr?tica anotada, m?todo libre y m?todo interpretativo-comunicativo; y se utilizaron t?cnicas tanto de la traducci?n directa como de la traducci?n oblicua. Se identificaron los elementos culturales, elementos coloniales y anticoloniales en el texto de partida y se usaron las t?cnicas de traducci?n que permitieron transferir o no transferir estos elementos a la cultura receptora. Mediante el an?lisis hecho se identificaron 24 diferentes categor?as de culturemas en la obra. Para traducir el texto y procesar los culturemas identificados se utilizaron 19 tipos de t?cnicas de traducci?n. Las t?cnicas utilizadas revelan que la estrategia principal usada por el traductor es domesticaci?n, es decir, en la mayor?a de los casos se opt? por adaptar los culturemas a la cultura receptora con el prop?sito de crear ?en ?sta?el mismo efecto que el texto de partida busc? crear en esa cultura.

Running Mechanics During the World's Most Challenging Mountain Ultramarathon

The aim of study was to examine the effects of the world's most challenging mountain ultramarathon (Tor des Geants [TdG]) on running mechanics. Mechanical measurements were undertaken in male runners (n = 16) and a control group (n = 8) before (PRE), during (MID), and after (POST) the TdG. Contact (tc) and aerial (ta) times, step frequency (f), and running velocity (v) were sampled. Spring-mass parameters of peak vertical ground-reaction force (Fmax), vertical downward displacement of the center of mass (Deltaz), leg-length change (DeltaL), and vertical (kvert) and leg (kleg) stiffness were computed. Significant decreases were observed in runners between PRE and MID for ta (P < .001), Fmax (P < .001), Deltaz (P < .05), and kleg (P < .01). In contrast, f significantly increased (P < .05) between PRE and MID-TdG. No further changes were observed at POST for any of those variables, with the exception of kleg, which went back to PRE. During the TdG, experienced runners modified their running pattern and spring-mass behavior mainly during the first half. The current results suggest that these mechanical changes aim at minimizing the pain occurring in lower limbs mainly during the eccentric phases. One cannot rule out that this switch to a "safer" technique may also aim to anticipate further damages.

Estimating social carrying capacity in protected Mediterranean mountain areas. Methodological orientation

The concept of social carrying capacity, though opens to debate and critique, is a valuable tool that enhances the management of recreational use in protected natural areas. In this study, conducted in Sierra de las Nieves natural park (Spain), we first categorised the hikers making use of the park and then, from the profiles obtained, analysed their perception of crowding on the trails. This assessment was subsequently used to assess levels of user satisfaction and thus to determine the psychosocial carrying capacity of the park. The results obtained can be extrapolated to most of the Spanish natural parks in Mediterranean mountain areas, due to their comparable levels of visitor numbers and to the prevalence of recreational hiking use. The results suggest that management efforts should be directed toward relocating trails outside the core areas, such that user preferences may be satisfied while less impact is made on the areas of highest environmental value.

Soil associated with rock outcrops in the Brazilian mountain ranges Mantiqueira and Espinhaço.

A Serra do Espinhaço e a Serra da Mantiqueira são duas cadeias de grande importância para o Brasil. Nas partes mais altas destas serras encontramse ecossistemas com características singulares, associados aos afloramentos rochosos, denominados Complexos Rupestres de Altitude. Esses ambientes apresentam características do solo e da vegetação distintas das áreas adjacentes. Os solos são em geral rasos, arenosos, com alta saturação de alumínio e teores variados de matéria orgânica. Neossolos Litólicos, Cambissolos e Organossolos são as classes de solo dominantes, diretamente associadas aos afloramentos, formando um mosaico de solos. Alguns solos encontrados nestes ambientes são endêmicos, em função das características peculiares da rocha matriz, da topografia e da vegetação, e sua preservação é estratégica por se tratar de solos raros e ameaçados de extinção. A matéria orgânica desses solos apresenta alto grau de humificação, com grande quantidade de frações solúveis, e a presença generalizada de fragmentos de carvão. Horizontes espódicos e rios negros estão tipicamente associados às áreas de afloramento de arenito e quartzito, sendo formados pela iluviação de compostos orgânicos, e sendo menos comuns nas áreas de granito. O oligotrofismo destes solos, associado a outras limitações de ordem química e física, induzem o desenvolvimento de estratégias de adaptação fisiológica e morfológica por parte da vegetação. A maioria destes ecossistemas é instável sob a condição climática atual, e a intervenção antrópica é um fator de aceleração do processo de degradação. A descrição detalhada dos solos nestes ambientes é fundamental para um melhor entendimento do seu papel nos processos ecológicos e para o desenvolvimento de políticas de conservação.

Genesis and classification of soils from subtropical mountain regions of Southern Brazil.

Soils formed in high mountainous regions in southern Brazil are characterized by great accumulation of organic matter (OM) in the surface horizons and variation in the degree of development. We hypothesized that soil properties and genesis are influenced by the interaction of parent materials and climate factors, which differ depending on the location along the altitudinal gradient. The goal of this study was to characterize and classify the soil, evaluate soil distribution, and determine the interactive effects of soil-forming factors in the subtropical mountain regions in Santa Catarina state. Soil samples were collected in areas known for wine production, for a total of 38 modal profiles. Based on morphological, physical, and chemical properties, soils were evaluated for pedogenesis and classified according to the Brazilian System of Soil Classification, with equivalent classes in the World Reference Basis (WRB). The results indicated that pedogenesis was strongly influenced by the parent material, weather, and relief. In the areas where basic effusive rocks (basalt) were observed, there was formation of extensive areas of clayey soils with reddish color and higher iron oxide contents. There was a predominance of Nitossolos Vermelhos and Háplicos (Nitisols), Latossolos Vermelhos (Ferralsols), and Cambissolos Háplicos (Cambisols), highlighting the pedogenetic processes of eluviation, illuviation of clay, and latosolization in conditions of year-long, large-volume, well-distributed rainfall and stability of land forms. In areas with acid effusive rocks (rhyodacites), medial or clayey soils were observed with lower iron oxide content, invariably acidic, and with low base content. For these soils, relief promoted substantial removal of material, resulting in intense rejuvenation, with a predominance of Cambissolos Háplicos (Cambisols) and lesser occurrence of Nitossolos Brunos (Nitisols) and Neossolos Litólicos (Leptosols). Soils formed from sedimentary rocks also tended to be more acidic, but with higher sand content, and the soils identified were Cambissolos Háplicos and Húmicos (Cambisols). Cluster analysis separated the soil profiles into three groups: the first and largest was formed by profiles originating from sedimentary rocks and rhyodacites; the second, smaller group was formed by four profiles in the Água Doce region (acidic rocks); and the third was formed by profiles derived from basalt. Discriminant analysis was effective in grouping soil classes. Thus, the study highlighted the importance of geology in the formation of soils in this landscape associated with climate and relief.

The experience of waterfalls

Landscape beauty has long been a concern of geographers and other scholars, but relatively little work has been done on the aesthetic analysis of specific landscape features such as mountain peaks and waterfalls. In Australia, as in many other parts of the world, waterfalls are popular scenic attractions, and this paper attempts to explain the widespread appeal of these landforms by examining them in the light of theories of landscape aesthetics, from the Picturesque and Sublime to arousal and prospect-refuge. While no single theory offers a complete explanation of our experience of waterfalls, this paper suggests that by using several theoretical approaches to the subject we are more likely to gain a full understanding of the way we respond to these landscape features.

Innovative ways to assist young anxious children

Although anxiety disorders have been shown to be one of the most common psychological disorders of childhood, aggressive, acting-out children are more often referred for treatment. This continues to be the case even though anxious distress in children affects both social adjustment and academic performance and has a widespread interference in most areas of their lives. This paper explores the incorporation of play therapy techniques into developmentally appropriate, educationally sound programs which recognise and cater for individual differences.

The response to dryness in Australia

The drought Australia now faces is leading to shifts in the perception of the continent, of Australians and the world. The ideals of lush green landscapes are making way for landscape designs in which dryness is a quality of the design. On a map of the world, Australia is enormous, and seems empty because development is concentrated around its edges. Its heart must be red, in the cultural projections of the world from images of Uluru, 'the rock', set in a flat desert with no relief. Of course the country is not really all desert - surely? - with low shrubs pretty much throughout. Inhabitation seems to cling to the edges where teh continent feels microclimatic effects from the adjacent oceans and edging mountain ranges, which screen the population from the real state of the environment - dry, harsh, amazing and unique. Australia is rightly proud of this harsh difference from its edges, but prefers the harshness to be 'out there'. At the moment however, the country is pretty much universally in drought, and the contrast between green and brown, that it has celebrated, even built its identity around, is disappearing to become brown throughout. Without the browning of Australia, some areas, such as tropical Queensland, are having their designed public landscapes and gardens revealed as an elaborate mythology, a landscape fraud.
