    In this research, we report the predation of Boana raniceps (Cope, 1862) by Leptophis ahaetulla (Linnaeus, 1758) in the rural area of Candeias do Jamari municipality, Rondônia state, southwestern Brazilian Amazon. Leptophis ahaetulla is a diurnal arboreal snake that can be found in a variety of environments such as dryland forests, flooded forests, and plantations. Its diet consists mainly of anurans and may include lizards. Boana raniceps belongs to the B. albopuncatata group.  There are few well-described reports on the predatory behavior of anurans by L. ahaetulla, as studies are generally based on stomach contents and not on photographic records. There are also few reports on the defensive behaviors of B. raniceps. In this research, predation of Boana raniceps was by Leptophis ahaetulla lasted about 15 minutes until complete ingestion and occurred at 2:00 PM on July 05, 2020. During predation, B. raniceps performed the defensive behavior, making distress calls. Recording this predation is essential to improve knowledge about the natural history of the species described here.Keywords: Predation; amphibian; behavior; diet; snakes.Nesta pesquisa, relatamos a predação de Boana raniceps (Cope, 1862) por Leptophis ahaetulla (Linnaeus, 1758) na área rural do município de Candeias do Jamari, estado de Rondônia, sudoeste da Amazônia brasileira.

    Get PDF
    Leadership paradigms are the attributes that a leader must possess for efficient and innovative leadership. Theory U is used as an argument in this discussion. The objective of this essay is to consider the paradigms of transformational leadership for the consolidation of a culture of innovation in the organization. This task of qualitative and exploratory research. The results of the present study suggest that consolidating a culture of innovation in the organization implies an impressive change in the modus operandi, with an open-minded team, also essential as a agent of change, led in an appropriate and creative environment. To make this possible, leadership must use the paradigms of transformational leadership as well as the culture-creativity-team trilogy. In addition, the change agent must disseminate the values of creativity and innovation in the everyday activities of the team, besides instigating internal actions that invigorate this culture

    SMEs need to develop approaches to innovation, with defined directions for developing processes based on innovation structures, and integrated with the innovation management approach. Few authors have discussed the measurement and development of scales applied in the area of administration, which provide the preliminary steps for validating measurement scales. What procedures are required to carry out the validation of scales and which constructs measure innovation and creativity? The method adopted in this theoretical essay was that of content analysis. The general objective of this work was to carry out a theoretical-conceptual study of the quantitative method in the measurement of innovation and creativity; and, as specific objectives, 1) to characterize the theoretical-conceptual evolution of a valid quantitative method for measuring innovation and creativity; 2) to develop concepts of ways to validate the quantitative methods used in the academic work on innovation and creativity; and to present constructs that would indicate the presence of innovation and creativity for the generation of modeling. To tackle the problem, the following question is proposed: how can innovation and creativity be validly measured? To answer this question, we first carried out a theoretical-conceptual review of the existing literature. We then used the review to conceptualize innovation and creativity, search for the main instruments to measure innovation and creativity, and set out the steps needed to validate a measurement scale for them. This work is directed to researchers in the area of ​​measurement and the development of scales

    UTAUT 2 is a model designed to be a starting point for investigating IT adoption and can be used to identify the factors that influence the intention to use it, as well as to be adopted by an organization. The main objective of this research is to validate the Unified Theory of Acceptance and Use of Technology (UTAUT2) model by applying the questionnaire to students of a university that has gone through the process of implementing a virtual learning environment. The method is the quantitative one, through the survey strategy. As for the time horizon of the survey, a transversal cut was chosen. The techniques and procedures adopted were the modeling of structural equations with partial least squares in the Smart-PLS 3 software. The instrument used in this article is an adaptation of the questionnaire of Venkatesh et al (2012). The results point to evidence of converging and descriminating validity. This research contributes to the Unified Theory of Technology Acceptance and Use (UTAUT) as it is applied in different environments, evidencing characteristics that may allow its generalization. Finally, in the practical scope, it is possible to use this tool to evaluate and plan the acceptance of a new technology in the organizational scope

    Human consumption of meat from roadkilled animals in the Southwestern Amazon

    The harvest of meat from wild animals is essential for the nutrition of many human populations in the Neotropics. Specific techniques are used to access wild meat, but collecting meat from road killed animals, or purposely run over animals to kill and consume the meat have not been documented so far. In this study we interviewed four residents of the state of Rondônia who claimed to consume roadkilled animals. Respondents cited only medium and large mammals (10 species in total) as the group from which wild meat is harvested, with one respondent claiming to intentionally run over the animals. The interviewees analyse the smell/putrefaction, swelling and exposure of viscera as criteria for not collecting the meat. The meat from roadkilled animals may pose a risk to the health of humans who consume it due to the foodborne diseases it may spread after the decomposition process. In addition, the practice of running over animals for consumption of their meat can cause potential impacts to the fauna and humans since it can reduce animal numbers and also cause serious accidents. Further investigations are needed to clarify whether this is widespread phenomenon occurring in other places of the Amazon and of the Neotropics

    This report adds information on the reproduction of Xenodon rabdocephalus (Wied-Neuwied, 1824) and describes the clutch size in a little-studied region of the Brazilian Amazon. We conducted field observations at the Military Jungle Police Base in the municipality of Porto Velho, state of Rondônia, southwestern Brazilian Amazon (9°5'31.56"S, 64°1'40.08"W). This individual of X. rabdocephalus was found to have a clutch of 11 eggs, with a size range of 26-36 mm (mean 29.36 ± 3.23 mm). The specimen analyzed in this report was deposited in the Coleção Herpetológica da Universidade Federal de Rondônia. We indicate the need for studies focused on the variation in the reproductive behaviour of the species in relation to seasonal fluctuation. Finally, reports of this kind help to understand the reproductive habits of X. rabdocephalus in nature.Keywords: false fer-de-lance; Eggs; Reproductive Behaviour; Natural history; Reproduction.Este relato acrescenta informação sobre a reprodução de Xenodon rabdocephalus (Wied-Neuwied, 1824) e descreve o tamanho da ninhada desta espécie numa região pouco estudada da Amazônia brasileira.

    Get PDF
    With the evolution of management practices, new management methods and tools were adopted in public entities in order to optimize the delivery of services to their steakholders. In this scenario, the Balanced Scorecard (BSC) offers an important tool to assist in the strategic management of public entities. Therefore, this work aims to generate a bibliometric analysis of the scientific production on the BSC tool in the public sector in the period of five years (2014-2018), to clarify the functionalities and to survey data through the Web Database of Science. The procedure to perform this review of scientific production involved, initially, access to the database, followed by research by the terms "BSC and Government" and "BSC and Public Management". Afterwards, they were exported and ordered in the matrix in order to perform the analysis of the elements obtained. The methodology used was of a descriptive and quantitative nature. The main results emphasize that the production registered in the database used is scarce, observing that only 27 publications were found in the studied temporal cutout. It also indicates that, in the range comprised, the Brazilian production was on a large scale together with the Australian and Portuguese production equated to other countries contained in the research and, finally, that there is an inconstancy in the publication of articles related to this subject. This article is structured as follows: introduction, theoretical reference, methodology, results and discussions and conclusion

    We report the opportunistic predation of Roadside Hawk (Rupornis magnirostris - Accipitridae) on subterranean termite (Coptotermes testaceus - Rhinotermitidae). This predatory behaviour was observed during an avifauna survey in the municipality of Candeias do Jamari, Rondônia, Brazil, in the southwestern Brazilian Amazon. There was a great abundance of C. testaceus alates because of heavy rainfall. This is the season when C. testaceus colonies produce alates in large numbers to found new colonies. The Roadside Hawk stayed on its perch and captured winged termites with little energy expenditure. The bird in question appeared to take advantage of the termite mating flight to feed opportunistically on the abundant alates. Although feeding on insects by R. magnirostris is well known, this is the first documentation of feeding on termite alates.Informamos de la depredación oportunista de Coptotermes testaceus (Rhinotermitidae) por Rupornis magnirostris (Accipitridae). Este comportamiento depredador fue observado durante un estudio de la avifauna en el municipio de Candeias do Jamari, Rondônia, Brasil, en el suroeste de la Amazonia brasileña. Había una gran abundancia de formas aladas de C. testaceus debido a las fuertes lluvias. Es el momento en que las colonias de C. testaceus producen formas aladas en gran número para fundar nuevas colonias. El aguilucho permaneció en su percha y capturó termitas aladas con poco gasto de energía. El ave en cuestión parecía aprovechar el vuelo de apareamiento de las termitas para alimentarse de forma oportunista de las abundantes termitas aladas durante los vuelos de apareamiento. Aunque la alimentación de insectos por parte de R. magnirostris es bien conocida, ésta es la primera documentación de alimentación de termitas aladas
