EFEK TEMPERATUR TERHADAP RESPIRASI, POLA PIGMENTASI, DAN PERILAKU KATAK POHON JAWA (Rhacophorus margaritifer Schlegel, 1837) DAN KATAK KONGKANG KOLAM (Hylarana chalconota Schlegel, 1837)
No full textMount Merapi is one of the mountain 's most active volcano in Indonesia . The last eruption of the volcano occurred in 2010. The eruption also on the southern slopes of the region. The southern slopes of Mount Merapi are known to have Anura species diversity is high enough. Comparison of the data between 2010 and 2012 showed that the diversity of Anura relatively stable. With these data indicate that the stability Anura located on the southern slope of Mount Merapi can withstand high temperatures as a result of the eruption. Anura mechanism to escape and survive the high temperatures is unknown. This research aims to study the effect of temperature on respiration, pigmentation patterns, and movement behavior and vocalization behavior. Another aim was to study the mechanism of the frog to avoid high temperatures. The sample used in this study were P. aurifasciatus and L. hasseltii. The study was conducted in the laboratory by using variations in temperature. Temperature variation used is the lowest temperature in the environment, the temperature within the normal range, and some degree of temperature above the normal temperature range. Data were collected for respiration , morphology , and behavior to determine the effect of temperature. Morphological observations made primarily against pigmentation patterns. Behavior observations carried on the movement behavior and vocalization behavior. Respiration increases at progressively higher temperatures in R. margaritifer while in H. chalconota will enter a period of rest at high temperatures. The pattern will change colors become brighter at higher temperatures and look good on R. margaritifer and H. chalconota. In R. margaritifer movement will be dominant in land area is compared to the higher regions, while in H. chalconota will more be on the waters. H. chalconota have a more diverse vocalizations when compared R. margaritifer. At high temperatures H. chalconota more concerned with physiological adaptation when compared with the behavior
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Keanekaragaman Spesies Amfibi (Ordo Anura) di Kawasan Cagar Alam Durian Luncuk II Provinsi Jambi
Full text linkIndonesia is home to 449 of the 7,757 Anura species that exist worldwide. An important component of the ecosystem, amphibians play a crucial role in maintaining environmental stability. Amphibians are quite vulnerable to changes in their environmental quality. The Durian Luncuk II Nature Reserve is an amphibian habitat in Batanghari Regency, Jambi Province. Covering 41.37 hectares of forest, this nature reserve was designated by the Minister of Forestry in 1997. Its lowland habitat and vegetation structure create an ideal environment for various amphibian species. This study aims to identify the amphibian species in the Duruan Luncuk II Nature Reserve and to determine the biological index. The research employs the Visual Encounter Survey (VES) method combined with the Line Transect system. The biological indices analyzed include the Diversity Index, Evenness Index, and species Richness Index. Data collection identified 11 amphibian species across four families. The Diversity Index was classified as moderate (2.1), while the Evenness Index indicated an almost uniform distribution (0.9). The species Richness Index was classified as low (2.8). Not all regions of CA Durian Luncuk II have been surveyed for this study. Therefore, a comprehensive survey in habitats that support amphibian encounters is still needed
Ethnozoological Study of Malay Tribal Communities in Mersam Village, Batanghari District
Full text linkMersam Village is located in Mersam District, Batanghari Regency, and has many local wisdoms that are still preserved to this day. The Malay tribe, as the indigenous group, is the primary source of local wisdom in this village. This study aims to identify the species of animals used, describe traditional practices, outline community knowledge, and analyze the reasons why the community continues to maintain these utilization activities. The research method employed is a qualitative descriptive approach, which includes stages of preliminary surveys, interviews, participatory and non-participatory observations, and documentation. The selection of informants used purposive sampling techniques for key informants and snowball sampling techniques for general informants. Documentation and identification of samples were conducted in the field. The results of this study indicate that ethnozoology in Mersam Village utilizes 32 animals species. Ethnozoology in Mersam Village related to consumption utilizes five species, which include customary meanings and unique processing methods. Ethnozoology in Mersam Village in terms of medicine utilizes 17 species, based on hereditary knowledge through treatments provided by shamans.
