The Amazon River Basin and its tributaries are characterized by extensive forested areas that become flooded every rainy season, where specimens listed above have been collected. Diagnosis. Males of Centroctenus varzea sp. n. resemble those of C. acara (Brescovit 1996: figs 25–26) by the size and position of median apophysis, but can be distinguished by median apophysis curved at tip, non-sinuous embolus, cymbium basally narrow, and by the large tip of the RTA (Fig. 9A). Females of Centroctenus varzea sp. n. resemble those of C. acara (Brescovit 1996: fig 27) by the lateral lobes conic, but can be distinguished by the lateral lobes projected posteriorly and the subquadrangular median sector of the epigynum (Fig. 9B). Description. Male (holotype).

Palp (Fig. 9A): tibia as long as cymbium; RTA close to tibial apex, elongated, cylindrical proximally and laminar and wide distally; cymbium elongate, with basal excavation; tegulum not projected; embolus with large base, with retrolateral basal projection and cylindrical distally; median apophysis cup-shaped and short; conductor hyaline, round and laminar. Female (paratype, MPEG 1187) . Coloration as described in male, excepted by the venter of the abdomen entirely yellow, covered by short black and white setae and elongated white setae (Fig. 11C, D, F). Total length 22.0. Carapace 9.7 long and 7.2 wide. Clypeus 0.42 high. Eye diameters: AME 0.37, ALE 0.25, PME 0.42, PLE 0.42. Chelicerae with 3 promarginal teeth, median larger; 4 retromarginal teeth, with same size, and 2 small proximal teeth; with intermarginal denticles (Fig. 10D).

Natural history. Centroctenus varzea sp. n. is one of the most abundant spiders in the flooded forests (várzea) of the Amazon River (Rego et al. 2009). Eighty-nine specimens were collected in samples scattered approximately 3,000 km along the river, at both margins and at the end of the flood season (from September to early November/2003). C. varzea sp. n. is a nocturnal wandering spider, found foraging at the leaf litter near rivers, lakes and streams. Few specimens were collected at night on beaches and ravines, and three individuals (less than 4% of the total) were caught during the daylight on shrubs and bare soil in non-flooded forest (terra-firme). The high abundance of juveniles and adults even in wet soil after flooding suggests that C. varzea sp. n. returns to flooded forests as the water descends into the Amazon River and its tributaries. Distribution. North of Brazil in the Amazon River basin (Fig. 12C).Published as part of Brescovit, Antonio D., Torres, Richard A., Rego, Felipe N. A.

No full textFoi revisada a morfologia de Crepidobothrium eirasi Rego and Chambrier, 1995, e feita uma análise cladística das seis espécies de Crepidobothrium Monticelli, 1900 [ viz. C. eirasi, C. gerrardi (Baird, 1860, C. viperis (Beddard, 1913), C. dollfusi Freze, 1965, C. garzoni de Chambrier, 1988 e C.lachesidis (MacCallum, 1921)], utilizando-se 23 caracteres e um grupo externo. Obtiveram-se duas árvores com parcimônia e 0,76 de indice de consistência. Ambas as árvores coincidem na posição de C. eirasi, o que sugere que Crepidobothrium é monofilético apenas quando C. eirasi é excluído do gênero. O novo gênero Pseudocrepidobothrium é proposto para alojar C. eirasi, e assim a monofilia de Crepidobothrium pode ser mantida. Pseudocrepidobothrium eirasi comb. n. é a única espécie parasita de peixe que possui ventosas sulcadas, enquanto todas as espécies de Crepidobothrium são parasitas de répteis da América do Su

Quantile-based fuzzy C-means clustering of multivariate time series: Robust techniques
No full textRobust fuzzy clustering of multivariate time series is addressed when the clustering purpose is grouping together series generated from similar stochastic processes. Robustness to the presence of anomalous series is attained by considering three well-known robust versions of a fuzzy C-means model based on a spectral dissimilarity measure with high discriminatory power. The dissimilarity measure compares principal component scores obtained from estimates of quantile cross-spectral densities, and the robust techniques follow the so-called metric, noise and trimmed approaches. The metric approach incorporates in the objective function a distance aimed at neutralizing the effect of the outliers, the noise approach builds an artificial cluster expected to contain the outlying series, and the trimmed approach removes the most atypical series in the dataset. As result, the proposed clustering methods take advantage of both the robust nature of these techniques and the capability of the quantile cross-spectral density to identify complex dependence structures. An extensive simulation study including multivariate linear, nonlinear and GARCH processes shows that the algorithms are substantially effective in coping with the presence of outlying series, clearly outperforming other alternative procedures. Two specific applications regarding financial and environmental series illustrate the usefulness of the presented methods. (c) 2022 The Author(s). Published by Elsevier Inc
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
