Abstract: the species c. externa, c. defreitasi, c. raimundoi and c. genanigra (neuroptera, chrysopidae) have great differences in the genitalia. these species were studied morphometrically by the distances between points of the head (eight linear measurements) to better identify them. the results, analyzed by multivariate statistics, showed that it is possible to identify measures that distinguish the individual, although some species are more distinguishable by morphometry. the canonical analysis showed that three of the four species, c. raimundoi, c. genanigra and c. externa, showed no major overlap between them, and their possible discrimination within the group, only c. defreitasi presented a low resolution according to this analysis, being overlapped with c. externa and c. genanigra, however, it is totally broken in c. raimundoi. the measures that contributed most to differentiation are related to the size of the head and especially the length of wrasse on the edge of the head, until the level of the eyes and antenna.

Abstract: The goal of this study was to analyze the diet of Moenkhausia intermedia (Eigenmann, 1908)from Diogo Lake, Rio Mogi-Gua u basin, municipality of Luís Ant nio, State of S o Paulo, southeastern Brazil.Sixteen stomachs were examined using the method of frequency of occurrence (%FO). According to our analysis28.79% of the food items were autochthonous, 48.48% allochthonous and 22.73% from non identified origins.Our results indicate that M. intermedia belongs to the omnivorous food guild, with a tendency to insectivory.The allochthonous items were the most frequent, with seeds showing a 100% frequency of occurrence andterrestrial insects 68.75%. Hence, an intact riparian vegetation is considered of great importance as a source offood for most aquatic invertebrates and fish.O presente trabalho teve como objetivo analisar a dieta de Moenkhausia intermedia (Eigenmann,1908), provenientes da Lagoa do Diogo, bacia do rio Mogi-Gua u, município de Luís Ant nio, S o Paulo.Foram examinados 16 est magos através do método de freqüência de ocorrência (%FO). A análise mostrou que28,79% dos itens alimentares s o autóctones, 48,48% alóctones e 22,73% de origem n o identificada. Osresultados indicam que M. intermedia pertence a guilda alimentar onívora, com tendência à insetivoria. Os itensalóctones foram os mais freqüentes, sendo que as sementes perfizeram 100% de freqüência de ocorrência e osinsetos terrestres 68,75%. Por isso, se considera de grande importancia fontes alóctones de alimento, sendonecessária a vegeta o marginal íntegra como fonte de recurso alimentar para a maioria dos invertebradosaquáticos e peixes.

Abstract: The goal of this work was to study the diet of Astyanax lineatus from the Taquara u Stream, inthe region of Serra da Bodoquena, State of Mato Grosso do Sul, central Brazil. The fish were caught using acombination of electric fishing, seines and hoop nets. The stomach contents of 15 specimens was analyzed usingthe frequency of occurrence, in which the number of fish that contain certain item is expressed as percentage oftotal number of fish examined with the content. Our results indicate that A. lineatus is an euryphagic species,with a tendency to insectivory, with a predominance of aquatic insects in its diet.O presente trabalho teve por objetivo avaliar e conhecer a dieta alimentar de Astyanax lineatus,provenientes do Córrego do Taquara u, Serra da Bodoquena (MS, Brasil), os peixes foram capturados por meiode pesca elétrica, redes de arrasto e peneiras metálicas. Foi analisado o conteúdo estomacal de 15 espécimesutilizando o método de freqüência de ocorrência, no qual o número de peixes que contém determinado item éexpresso como porcentagem do total de peixes examinados com conteúdo. De acordo com os dados, A. lineatusfoi considerada uma espécie eurifágica com tendência à insetivoria, com predominancia de insetos aquáticos emsua dieta.
Christian attitudes in scholarship: The role of worldviews
Renato Coletto
Koers : Bulletin for Christian Scholarship , 2012, DOI: 10.4102/koers.v77i1.33
Abstract: This article starts from the realisation that a few different approaches to science and scholarship are implemented within different Christian traditions. In an attempt at identifying the reasons behind such differences, it is argued that the approach to science and scholarship adopted in each Christian tradition corresponds to a considerable extent to the worldview accepted in that tradition. In this article, several versions of the main Christian worldviews are identified and related to the work of authors (e.g. Murphy, the Theonomic movement, Barbour, Van Huyssteen, Wolterstorff) who were not discussed in previous works on this topic. The possibility of ‘mixing’ the worldviews (thus adopting an eclectic approach) is also discussed. The proposed taxonomy may be used to understand at a deeper level both individual authors and trends, and also to sketch a ‘map’ of the different movements, contributors and available options. It is argued that the different worldviews are not equally valuable and that the reformational worldview should be regarded as more integrally and originally biblical. The article ends with a call to consistency for the sake of sound Christian scholarship.
Wolterstorff’s critique of the reformational view of scholarship in his essay On Christian learning
R. Coletto
Koers : Bulletin for Christian Scholarship , 2009, DOI: 10.4102/koers.v74i3.131
Abstract: In this article I analyse Wolterstorff’s criticism of aspects of the reformational approach to science and scholarship as expressed in his essay “On Christian learning” (Wolterstorff, 1989). I argue that those allegations by Wolterstorff are not always well-founded, fully justified or supported by rigorous arguments. In particular, I examine Wolterstorff’s complaints concerning the “connection between religion and scholarship”, religious “totalism”, expressivism and the issue of a “uni-directional” view of science and religion. The purpose of this article is to remove obstacles that would hamper dialogue and cooperation between scholars in the traditions of reformational philosophy (Dooyeweerd et al.) and reformed epistemology (Wolterstorff et al.).
Towards a theory of presuppositions: Kuyperian contributions
R. Coletto
Koers : Bulletin for Christian Scholarship , 2011, DOI: 10.4102/koers.v76i1.8
Abstract: One of the most important themes of contemporary philosophy of science was the discovery of presuppositional beliefs and frameworks as factors influencing scientific research. This article explores the development of a theory of presuppositions within Kuyperian philosophy. The authors discussed in this study represent a few Kuyperian families: Dooyeweerd, Vollenhoven (briefly), Wolterstorff, Klapwijk, Duvenage and Botha. The perspective is both historical and systematic. Historically, it refers to the main authors who contributed to establishing the basic features of such a theory. Systematically, the article tries to evaluate the proposals of each contributor by assessing their value and limits. In doing so, the author often defends his own preferences and indicates the directions to be followed.
Traces of neo-Calvinism in France and Italy
R. Coletto
Koers : Bulletin for Christian Scholarship , 2010, DOI: 10.4102/koers.v75i1.77
Abstract: This article deals with the history of the neo-Calvinist movement in France and Italy. The efforts of the Dutch Reformational movement to communicate with French (mainly reformed) Christians are highlighted. A brief overview of the achievements of the few French scholars involved in this development is sketched and their publications are mentioned, together with a few conferences and organisations. Neo-Calvinism reached Italy as well, via the input of French lecturers and publications. The few developments of neo-Calvinism in Italy are recorded as well. Also, the gradual drift towards vantilian and reconstructionist positions (in both countries) is detected and discussed. An evaluation of these developments is provided, together with a few final considerations and questions which should help learning lessons from the past and preparing better strategies for the future.
The re-appreciation of the humanities in contemporary philosophy of science: From recognition to exaggeration?
Renato Coletto
Koers : Bulletin for Christian Scholarship , 2013, DOI: http://dx.doi.org/10.4102/koers.v78i2.64
Abstract: In the course of the centuries, the ‘reputation’ and status attributed to the humanities underwent different phases. One of their lowest moments can be traced during the positivist period. This article explored the reasons underlying the gradual re-evaluation of the scientific status and relevance of the humanities in the philosophy of science of the 20th century. On the basis of a historical analysis it was argued that on the one hand such recognition is positive because it abolishes an unjustified prejudice that restricted the status of ‘science’ to the natural sciences. On the other hand it was argued that the reasons behind such recognition might not always be sound and may be inspired by (and lead to) a certain relativism harbouring undesired consequences. In the final part of this article (dedicated to Prof. J.J. [Ponti] Venter) a brief ‘postscript’ sketched his evaluation of the role of philosophy.
Presuppositions and the challenge to objectivity in late-modern philosophy of science: causes and possible remedies
R. Coletto
Koers : Bulletin for Christian Scholarship , 2007, DOI: 10.4102/koers.v72i4.216
Abstract: The history of late-modern philosophy of science introduces us to a growing emphasis on presuppositions accompanied by a growing relativistic attitude concerning the possibility of scientific objectivity. Aspects of the latter historical developments are traced in some of the most important philosophers of science of the 20th century. An analysis of the possible causes of the phenomenon is also provided. The predominance of the freedom- pole of the humanist ground motive requires a conception of science in which the creative presuppositions of the knowing agent play an increasingly crucial role. Two “remedies” for a more balanced understanding of the role of presuppositions are indicated. The first one has to do with the recognition of a broad variety of ideological standpoints, stemming from different religious commitments. The second one recommends the recognition of the universal order for reality, which implies two consequences. First, our presuppositions do not have the power of determining our scientific observations of reality completely. Second, scientific research does not proceed only according to our presuppositional frameworks but follows a structural order. A few reflections on the nature of scientific objectivity conclude the article.
When 'paradigms' differ: scientific communication between skepticism and hope in recent philosophy of science
R. Coletto
Koers : Bulletin for Christian Scholarship , 2008, DOI: 10.4102/koers.v73i3.169
Abstract: The first half of this article illustrates how contemporary humanist philosophy of science got caught up in a gradual loss of confidence concerning the possibility of sound communication among scholars holding on to different paradigms or presuppositions. The second half is dedicated to the responses provided by a Christian school of philosophy to the bleak possibility of a communication crisis. The resources deployed by the reformational school of philosophy are argued to constitute valuable instruments to create a more hopeful attitude towards scientific dialogue. A final note is dedicated to the possible causes of the difficulties experienced in this area of reflection by contemporary humanist philosophy of science.
