ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Performance Evaluation of Resource Management in Cloud Computing Environments.

Cloud computing is a computational model in which resource providers can offer on-demand services to clients in a transparent way. However, to be able to guarantee quality of service without limiting the number of accepted requests, providers must be able to dynamically manage the available resources so that they can be optimized. This dynamic resource management is not a trivial task, since it involves meeting several challenges related to workload modeling, virtualization, performance modeling, deployment and monitoring of applications on virtualized resources. This paper carries out a performance evaluation of a module for resource management in a cloud environment that includes handling available resources during execution time and ensuring the quality of service defined in the service level agreement. An analysis was conducted of different resource configurations to define which dimension of resource scaling has a real influence on client requests. The results were used to model and implement a simulated cloud system, in which the allocated resource can be changed on-the-fly, with a corresponding change in price. In this way, the proposed module seeks to satisfy both the client by ensuring quality of service, and the provider by ensuring the best use of resources at a fair price

A coleta seletiva de resíduos sólidos: uma ação aplicada no Projeto Rondon com crianças de Santa Luzia do Itanhi - SE

During 13 days of january and february 2011, the State University of Ponta Grossa took part in Project Rondon performing actions in the Santa Luzia do Itanhi city in Sergipe state. One of the biggest problems facing for the local population is about the solid residue spread all over the city. The task was propose interactive activities to 6 to 11 years old children in order to deal with the selective collection of solid residue. The results were productive, because it was realized children understood the activities� purpose and they�ve run them properly, allowing developing attitudes of care for the living space to protect and improve it. From Project Rondon�s actions was possible to deal with a multidisciplinary team to create knowledge multipliers and develop skills in searching for alternatives to environmental problems.Durante 13 dias dos meses de janeiro e fevereiro de 2011, a Universidade Estadual de Ponta Grossa participou do Projeto Rondon, realizando ações no município de Santa Luzia do Itanhi no estado de Sergipe. Um dos maiores problemas enfrentados pela população luziense é em relação aos resíduos sólidos distribuídos por vários pontos da cidade. O objetivo deste trabalho foi realizar, com crianças de 6 a 11 anos, atividades interativas para que se pudesse trabalhar a coleta seletiva de resíduos sólidos. O resultado foi produtivo, pois com o desenvolvimento do trabalho percebeu-se que as crianças compreendiam o objetivo das atividades e as executavam corretamente, possibilitando desenvolver atitudes de cuidado com o espaço em que vivem para protegê-lo e melhorá-lo. Com a ação do Projeto Rondon foi possível trabalhar com uma equipe multidisciplinar, criar multiplicadores de conhecimento, e desenvolver habilidades na busca de alternativas para os problemas ambientais

Smallpt analysis.

<p>As new vCPUs were added, the competition for physical resources was greater, and this reduced the execution mean time. However this only occurred until the vCPUs number was less than, or equal to, the physical CPU number. After this point, there were increases in the response variable.</p

Factors analysis.

<p>As the power of the instance increased, the EMT was reduced. This behavior has a direct bearing on the cost and the amount of resources that are used.</p

Results of the Execution Mean Time.

<p>Different applications were executed by different instances in environments with and without ReMM.</p

Analysis of the influence of factors.

<p>In this analysis the levels in the number of vCPUs factor were combined in 2–2 to define the influence of each factor on the number of served requests per second by taking account of environments with 1 and 4 VMs.</p

Use of the processor.

<p>The way that the Credit Scheduler combines the vCPUs and the CPUs creates situations in which the physical cores can be idle, balanced or overloaded.</p

Monitoring and scalability process.

<p>At intervals of time, the Performance Monitor collects information about the execution and sends it to ReMM. ReMM analyses the performance information and may or may not apply the resources scalability, which affect the costs.</p
