Stability of Brazilian Seasonally Dry forests under Climate Change: Inferences for Long-Term Conservation

American Journal of Plant Sciences 2013年第4期4卷 792-805页

We identified climatically stable areas of seasonally dry forests (SDfs) from Central Brazil through time and assessed the effectiveness of the current reserves network in representing these climatically stable areas, as well as areas of high suitability in the present or in the future only. We used an ensemble approach based on several methods for ecological niche modelling (ENMs) to obtain potential distributions 16 SDf’ species for past (last glacial maximum), present, and future (end of XXI century) climate scenarios. We then computed how many current Brazilian reserves matched both stable areas (suitable areas for all time periods), present and future geographical ranges alone for each species, in a multi-level gap analysis. We found range shifts due to climate changes for SDf’ species. Although the future geographical range and stable areas for all analyzed species matched at least with one reserve, many protected areas will lose importance in protecting suitable areas for species in the future. Moreover, the current Brazilian reserves cover only a small amount of their climatically stable areas. However, some reserves will be suitable for many SDf’ species (90%) at the same time, but climatically stable for only half of them. Our findings show that vegetation community from SDfs may persist in Brazilian territories until the end of XXI century, and challenges about long-term conservation of the SDfs may be partially reached with already existing Brazilian reserve network, however the reserves should be connected to permit habitat tracking.

Temporal Variations of the Chemical Composition of Three Seaweeds in Two Tropical Coastal Environments

Open Journal of Marine Science 2014年第2期4卷 118-139页

The seaweeds Chaetomorpha antennina, Gymnogongrus griffithsiae and Ulva fasciata were studied regarding tissue concentrations of total nitrogen, total phosphorus, total protein, hydrosoluble protein, total carbohydrate, chlorophyll a and total carotenoid throughout a 39-month survey in two coastal environments of Rio de Janeiro State, Brazil. One of the sites (Itapuca Stone) has high concentrations of dissolved nutrients and an intense long-term process of cultural eutrophication;the second site (Bananal Inlet) is thought to have lower concentrations of dissolved nutrients and no relevant anthropic impact. Seaweeds experienced changes in the concentrations of the substances in the thalli;however they did not show any cyclic seasonal pattern, except for pigments, with lower values in summer in both sites. The differences found for each species in each sampling at the sites were small (e.g. U. fasciata, more total nitrogen at Itapuca Stone) or absent (e.g. C. antennina, no significant differences for hydrosoluble protein in the sites). Differences in the concentrations of dissolved nutrients in the sites did not generate contrasting chemical profiles in the seaweeds. There is no evidence of nitrogen- or phosphorus-limitation in any season. It is presumable that the concentrations of dissolved nutrients at the nutrient-poorer site are sufficient to generate high concentrations of the substances in the thalli of the species tested, similar to the concentrations measured in the eutrophic site. Experimental data are needed to elucidate the factors that promote the success of the species tested under contrasting nutrient availability and environmental disturbance.

Applied Mathematics 2021年第7期12卷 546-555页

作者： José Bavio carina fernández Patricia fernández Beatriz Marrón Depto. de Matemática Universidad Nacional del Sur Bahía Blanca Buenos Aires Argentina IACA Laboratiorios Bahía Blanca Buenos Aires Argentina

In this study, we analyze how vitamin D (VD) serum levels flow with latitude and throughout seasons of the year within a population sample over three years, taking into account that VD is mainly photosynthesized in the skin from sun exposure. Vitamin D levels have been measured in 80,763 patients during 2013, 2014, and 2015. To accomplish the objectives, we first perform some inference tests like two-way Analysis of Variance (ANOVA) followed by post-hoc tests. Secondly, we develop time series techniques including cross correlation calculations. Least than 10% of the sample had healthy VD levels, which should be a fact of public health major concern. The effect of the interaction between the two factors, zones and seasons, was proved by ANOVA. The mean values which are significantly different were determined by post hoc test. furthermore, we find that mean serum VD levels, measured as 25-hydroxy-VD, follow a seasonal lag pattern of 9 weeks, a delay for minimum and maximum values after the respective equinoxes and daily sunlight duration. Reliable estimates of the population are provided in the present study, since one of the strengths is its huge sample size. We have quantitatively characterized the seasonality of serum vitamin D levels in the argentine and the seasonal lag pattern has been determined for the study region.

Static Digits Recognition Using Rotational Signatures and Hu Moments with a Multilayer Perceptron

引用

Engineering（科研） 2014年第11期6卷 692-698页

作者： francisco Solís Margarita Hernández Amelia Pérez carina Toxqui Autonomous University of Mexico State Toluca Mexico Polytechnic University of Tulancingo Tulancingo Mexico

This paper presents two systems for recognizing static signs (digits) from American Sign Language (ASL). These systems avoid the use color marks, or gloves, using instead, low-pass and high-pass filters in space and frequency domains, and color space transformations. first system used rotational signatures based on a correlation operator;minimum distance was used for the classification task. Second system computed the seven Hu invariants from binary images;these descriptors fed to a Multi-Layer Perceptron (MLP) in order to recognize the 9 different classes. first system achieves 100% of recognition rate with leaving-one-out validation and second experiment performs 96.7% of recognition rate with Hu moments and 100% using 36 normalized moments and k-fold cross validation.

本文讨论了波罗的海水体(溶解相)、悬浮颗粒物(SPM)、沉积物捕获物和沉积物中多氯联苯(PCBs)的浓度,及与其有关的有机碳和脂类作为吸附基质的动力学。在沉降过程中,对大多数所研究的PCB来说,悬浮物中PCB的碳和脂含量为基质浓度的增加引起所观测的log K_(DC)值的增加并达到1个数量级以上。看来,沉降颗粒内的疏水性有机化合物(HOCs)被保留,有机碳和脂类被分解,而不是在沉降过程中对多氯联苯持续吸收。然而,对沉积物在长时间维持高浓度的解释,必然归因于在这一些老化过程中,有机基质对HOCs吸附容量的增加。研究结果对HOCs在水环境中迁移转化的现有模型非常重要,并暗示使用单一方程来估计悬浮物中HOCs的平衡浓度将显著低估沉降颗粒中HOCs的浓度。
