•The canopy presents higher richness compared to the trunk.•The composition exhibited similarity both among the vegetation types Dwarf cloud forest and the strata.•The vegetation type with more wind ...incidence and short phorophytes presented lower richness.•The stratification of the Bromeliaceae and Polypodiaceae families played a significant role in the species distribution pattern.
Vascular epiphytes are plants that grow on phorophytes, and their distribution may vary both horizontally and vertically. Understanding the factors shaping epiphyte distribution and their relationship with alpha and beta diversities is crucial for understanding richness and composition patterns. We investigated alpha and beta diversity variation in the vertical and horizontal stratification of epiphyte communities across different vegetation types in a dwarf cloud forest. Twenty-four 20 × 10 m plots were established in three vegetation types defined by distinct soil characteristics, different phorophyte height and differences in tree species composition in Parque Estadual do Ibitipoca, Minas Gerais, Brazil. Phorophytes were divided into four strata: (A) base of the trunk, (B) lower trunk, (C) inner canopy, and (D) outer canopy. Alpha and beta diversity analyses were performed for each site. We found a reduced stratification in the area, indicating minimal composition differences between the strata. However, the canopy exhibited greater species richness than the trunk. Vegetation types F1 and F2 displayed higher richness compared to F3. Orchidaceae was the richest family overall, while Bromeliaceae and Polypodiaceae were more frequent. Holoepiphytes were highly representative, demonstrating consistent patterns of richness, composition, and dispersion, with anemochorous species being the most abundant. This study highlights the unique patterns of epiphyte stratification, emphasizing the importance of biotic and abiotic characteristics in colonization processes. Despite the low canopy of the forest, the non-uniformity in stratification demonstrates that formation characteristics, such as height, play a significant role in shaping epiphyte richness and composition patterns.
On behalf of the Program Committee, a very warm welcome to the Seventh Italian Conference on Computational Linguistics (CLiC-it 2020). This edition of the conference is held in Bologna and organised ...by the University of Bologna. The CLiC-it conference series is an initiative of the Italian Association for Computational Linguistics (AILC) which, after six years of activity, has clearly established itself as the premier national forum for research and development in the fields of Computational Linguistics and Natural Language Processing, where leading researchers and practitioners from academia and industry meet to share their research results, experiences, and challenges.

Los socorristas utilizan, como parte del rescate acuático, el estilo crol y crol con la cabeza fuera del agua. Los estudios sobre gasto energético y variables fisiológicas complementarias obtenidas ...durante estrategias de rescate acuático son escasos. El objetivo de este estudio fue comparar la energética y el rendimiento del estilo crol y crol con la cabeza fuera del agua realizado por socorristas. En este estudio participaron voluntariamente 21 socorristas militares. Se realizaron dos tests a máxima intensidad: 100 metros en crol y en crol con la cabeza fuera del agua. En cada test se identificaron datos fisiológicos (medición directa de consumo de oxígeno, lactoacidemia y frecuencia cardíaca), la escala de esfuerzo percibido y la velocidad media de natación (análisis de vídeo bidimensional). Se calculó la contribución de cada fuente de energía y el coste energético. Se utilizaron estadísticos descriptivos e inferenciales para α < .05. El rendimiento fue mejor en crol, los resultados fisiológicos fueron similares entre crol y crol con la cabeza fuera del agua y el coste energético fue mayor en crol con la cabeza fuera del agua (1.90 ± 0.33 kJ·m-1), comparado con el crol (1.51 ± 0.33 kJ·m-1). En conclusión, el estilo crol con la cabeza fuera del agua es menos eficiente que el crol.
Lymphocyte activities were determined in a population of 26 institutionalized aged subjects, selected as healthy according to the SENIEUR protocol and previously reported to display immunological and ...endocrinological abnormalities correlated with depressive disorders. The lymphocyte mitotic response to PHA, which was reduced in aged as compared to adult subjects, was found to be significantly lower and negatively correlated with the depression score in the elderly subjects. In supernatants of PHA-stimulated lymphocyte culture from aged subjects, IL-2, IL-4 and gamma-IFN levels were very low and more severely affected in the depressed aged group. Each cytokine production was negatively correlated with age and depression score. NK activity was lower in the aged and it could be augmented by the addition of IL-2 or alpha-IFN, even though to a lesser extent than in the adult subjects. The nondepressed aged displayed higher levels of IL-2 inducible NK activity than the depressed aged subjects. IL-2 and alpha-IFN stimulated NK activities were negatively correlated with depression score. The present work indicates that the psychological status could affect lymphocyte reactivity in the aged. Given the relatively high frequency of affective disorders in these subjects, the psychological status should be considered in studies of immune senescence.
