We present a revision of Glebionis coronaria in the Mediterranean area based on: a) micro-morphology of the disc floret cypselas observed with a high-resolution confocal microscopy; b) measurements of the disc cypsela with a stereoscopic microscope - duly scaled; c) its distribution in several bioclimatic belts; d) field observations; e) comparisons of herbarium samples. Because of this study, ...
Many machine learning (ML) approaches are widely used to generate bioclimatic models for prediction of geographic range of organism as a function of climate. Applications such as prediction of range shift in organism, range of invasive species influenced by climate change are important parameters in understanding the impact of climate change. However, success of machine learning-based approache...
This paper deals with 8 new species of Phlugiolopsis from Yunnan and Guizhou, China, supplements the images of P ventralis Wang, Li & Liu, 2012 and details the morphology of male stridulatory files and mandibles for 9 Phlugiolopsis known species. Distribution of poorly known species and new species are presented. A key to all known species is provided. Based on the known distribution of Phlugio...
Gypsophila bermejoi G. López is an allopolyploid species derived from the parental G. struthium L. subsp. struthium and G. tomentosa L. All these plants are gypsophytes endemic to the Iberian Peninsula of particular ecological, evolutionary and biochemical interest. In this study, we present evidence of a possible repression on the process of G. bermejoi speciation by climatic factors. We model...
In terms of ecology forecast effects of desertification, the purpose of this study is to develop a predictive model of growth and adaptation of species in arid environment and bioclimatic conditions. The impact of climate change and the desertification phenomena is the result of combined effects in magnitude and frequency of these phenomena. Like the data involved in the phytopathogenic process...
We present a method for visual and interactive geospatial redescription mining. The goal of geospatial redescription mining is to characterize geospatial areas using two different descriptions, such as their bioclimatic features and fauna. Indeed, one application of geospatial redescription mining is finding bioclimatic niches, i.e. explaining the distribution of species using their bioclimatic...
Correspondence analysis was applied to sand fly sampling in 865 stations from the Western Mediterranean basin. The position of each of 24 species was determined with respect to the bioclimatic belts. Thus, the multidimensional analyses manifest clear correlations between bioclimatic belts and their expression in the area, the phytosociological groupings, and vector species of visceral and cutan...
The influence of the bioclimatic elements upon the building behavior is analyzed using Matlab/ Simulink and toolbox HAMBASE. However, this software does not take into account a crucial element characteristic of these bioclimatic buildings, the air density. We propose an enhancement of existing computer code by adding a model to calculate the air density characteristic along the already existing...
abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
This paper presents various aspects, which characterise the traditional architecture in the town of Florina, north-western Greece, and can be related to bioclimatic and environmental architecture. The study is based on the documentation and the analysis of the architectural and bioclimatic aspects of a sample of forty (40) remaining houses of the 19th and the beginning of the 20th century. The ...
