title: Anatomical study of Orchidaceae epiphytes species occurring in indigenous territory in the Parque Estadual da Serra do Tabuleiro (P.E.S.T.), Santa Catarina, Brazil

description: Abstract Besides their ecological importance, epiphytic species of Orchidaceae play economic and social roles through their commercialization and some are at great risk of extinction. The objectives of this study were to characterize the leaf and root anatomy of fourteen epiphytic Orchidaceae species, which occur in indigenous territory in the Parque Estadual da Serra do Tabuleiro (P.E.S.T.), Santa Catarina, Brazil and to identify adaptive anatomical characteristics related to the epiphytic habit. The species are commercialized by the Guarani and were collected during interviews and guided tours with Guarani in the indigenous territory. The results reveal the species have many morphoanatomical structures that are useful during water shortages resulting from the epiphytic habit. Notable characteristics are related to reserving water (i.e., pseudobulbs and a hypodermis with water-storage cells) and resistance to desiccation in the leaf (i.e., conspicuous cuticle, suprastomatic chamber and extraxylary and pericyclic fibers) and root (i.e., tilosomes and/or exodermal thickening and cortex cells with phi thickenings or sclereids). Descriptions and the identification of adaptive characteristics of epiphytic plant species are useful for conservation and cultivation studies, especially for plants commercially used by the Guarani Indians.

title: Prior fertilization enables higher survival of relocated terricolous orchids?

description: Abstract The construction of highways causes several impacts on the environment, including, the suppression of vegetation, which can lead to reduced biodiversity. One mitigating measure involves reallocating plant to protected areas and orchids might be important for this use. An example could be the terricolous orchid Sauroglossum nitidum. In an attempt to optimize the survival of S. nitidum following reallocation, the aim of this study was to investigate whether the fertilization can increase the survival of this orchid. For this, five lots with ten plants per lot were randomly separated, with five plants submitted to soluble fertilization with NPK 10-52-10 (1 g.L-1), spraying each plant with 1 mL of the fertilizer, and the other five sprayed with the same volume of distilled water. This treatment was repeated fortnightly for two months before reallocation. The plants were relocated in September 2015 and monitored monthly until November 2016. Overall orchid survival was 92%. Additionally, flowering was observed to be significantly higher in fertilized plants. In conclusion, reallocation of S. nitidum with previous NPK fertilization is recommended.

title: Temporal occurrence of Ceratium furcoides (Dinophyceae: Ceratiaceae) during an extreme drought season in Pernambuco state, Northeast Brazil

description: Abstract Ceratium furcoides is an invasive species that has caused ecological imbalance in several reservoirs in Brazil. This study investigates the main factors that may favor the occurrence of Ceratium furcoides blooms in a tropical reservoir from the Northeast Brazil, during an extreme drought season. Samples containing phytoplankton were collected monthly from February to September 2017. Quantitative analysis of C. furcoides was performed and the cell volume was estimated using geometric formulas. Mean biovolume of C. furcoides showed significant differences, ranging from 0.78 mm3 L-1 to 11.29 mm3 L-1 reported in March and September, respectively. Environmental parameters presented low oscillation throughout the study, except the conductivity. Significant relationships among the C. furcoides biovolume, water temperature and soluble reactive phosphate were observed. The findings reported here suggest that adverse conditions caused by a drought season did not negatively affect this species.

title: Phanerogamic flora of central-north coastal of Rio Grande do Sul state, Brazil

description: Abstract An inventory of phanerogams from the central-north coastal plain of Rio Grande do Sul, Brazil, is presented here. During two years, all the phytophysiognomies of the municipalities of Cidreira, Balneário Pinhal and Palmares do Sul were sampled. The species were classified according to the environment of occurrence, preferential habit, naturalness and degree of threat. A total of 383 species were collected from 92 families, of which 365 (95%) native and 18 (5%) were exotic. The richest families were Asteraceae (45), Poaceae (30), Cyperaceae (24) and Fabaceae (23). The field formations presented the highest floristic richness (146), followed by forest (132) and wetland (17). The preferred habits were herbaceous and shrub (68%), habit tree (20%), climbers (6%), epiphytes (6%) and parasites (1%). In all, 18 species were registered in some threat category. The data found represent a high species richness for the region, and are compatible with the estimates and those found by other authors in coastal areas, and are basically due to the phytophysiognomic and geographic mosaic of the region and the influence of the Mata Atlântica and Pampa biomes. Threats to the local flora were evidenced, mainly related to the degradation of the natural habitats by the agricultural and silvicultural crops.

title: Evaluation of Unmanned Aerial Vehicles Cooperative Combat Effectiveness Based on Conditional Entropy Combination Weight Method

description: ABSTRACT For evaluating the cooperative combat effectiveness of unmanned aerial vehicles (UAVs), traditional entropy methods have an undue weight coefficient of the index due to its high degree of dispersion, and the interrelationship between the indices are not considered. To deal with this problem, this paper proposes a conditional entropy combination weighting method for evaluating the cooperative combat effectiveness of UAVs. Firstly, with the aim of establishing the UAV cooperative combat index system, the modified Delphi method has been combined with analytic hierarchy process (AHP) and interval estimation. This method has been used for estimating the degree of contribution of each index and to remove the indices that have a low contribution. Secondly, the principle of conditional entropy has been introduced for modifying the entropy method with the consideration of the interrelation between the indices. Finally, the modified entropy and AHP have been combined to assign the final weight in the UAV cooperative combat system. Testing results demonstrate that the index system established by this method is more comprehensive and reasonable as compared to that established by the traditional Delphi method. Compared with the single weighted method, this method is more suitable for the evaluation system of UAVs cooperative combat effectiveness.

title: The Evaluation of Effectiveness for the Collaborative Combat of an Unmanned Aerial Vehicle Based on Grey Minimum Entropy

description: ABSTRACT The main points to the evaluation of effectiveness for the collaborative combat of the unmanned aerial vehicle (UAV) lie within the construction of a reasonable indicator system and an accurate contribution model. As for point one, this article introduces a new method combining the Delphi consulting method and the principal component analysis method to avoid the underlying subjective and time-consuming defects of the existing methods. As for another point, a weighting method is adopted combining the subjective and objective parameters to minimize the errors caused by a single entity. Firstly, the modified grey relational degree analysis method is used to obtain the subjective weight, which can reduce the influence of the extreme values and outliers by enhancing the selection process of the reference sequence. Secondly, this paper adopts the weight of minimum entropy weight method to obtain the objective weight; it can avoid the information loss caused by the original method, which only determines the weight based on the frequency of each element present in the effective combination. At last, the principle of minimum relative entropy is adopted to obtain a more reasonable weight distribution coefficient. The simulation experiments established the rationality and effectiveness of the proposed method.
