Hábitos Alimenticios De Pygocentrus Cariba Y Chalceus Epakros (Pisces, Characiformes: Characidae) En Dos Localidades De La Baja Orinoquia Colombiana
Memoria de la Fundación La Salle de Ciencias Naturales 2006 (“2005”), 164: 129-141 Hábitos alimenticios de Pygocentrus cariba y Chalceus epakros (Pisces, Characiformes: Characidae) en dos localidades de la baja Orinoquia colombiana Javier A. Maldonado-Ocampo y Hernando Ramírez-Gil Resumen. Este trabajo analiza la dieta de Pygocentrus cariba y Chalceus epakros (Characidae), especies capturadas entre mayo de 1998 y junio de 1999, en sistemas de la baja Orinoquia, Colombia. Para P. cariba se analizaron 156 individuos adultos, encontrándose siete categorías de alimento. A pesar de presentar un espectro variado de ítems alimenticios, unos pocos son dominantes, siendo los restos de peces (IIR= 38,38%; IAi= 91,1%) y los restos de material vegetal (IIR= 3,09%; IAi= 7,3%) los más ingeridos, aunque éste último puede ser consumido accidentalmente. En cuanto a la variación estacional en la dieta, los restos de peces fueron la categoría principal aunque no se encontraron diferencias estadísticamente significativas entre períodos en el índice de importancia relativa (IIR) o en el índice alimentario (IAi). Se analizaron 163 individuos de C. epakros que presentaron cuatro categorías de alimento, de las cuales dos, restos de material vegetal (IIR= 29,88%; IAi= 56,6%) e invertebrados (IIR= 22,72%; IAi= 43%) fueron las de mayor consumo en ambos períodos, no obstante, se presentaron diferencias estadísticamente diferentes entre épocas. Ambas especies presentan una dieta omnívora (oportunista), aunque P. cariba con tendencia piscívora y C. epakros con tendencia herbívora. Palabras clave. Ecología trófica. Arari. Caribe pechi rojo.

Hyperspectral Data As a Biodiversity Screening Tool Can Differentiate
www.nature.com/scientificreports OPEN Hyperspectral data as a biodiversity screening tool can diferentiate among diverse Neotropical fshes M. A. Kolmann1,2*, M. Kalacska3, O. Lucanus4, L. Sousa5, D. Wainwright6, J. P. Arroyo‑Mora7 & M. C. Andrade8 Hyperspectral data encode information from electromagnetic radiation (i.e., color) of any object in the form of a spectral signature; these data can then be used to distinguish among materials or even map whole landscapes. Although hyperspectral data have been mostly used to study landscape ecology, foral diversity and many other applications in the natural sciences, we propose that spectral signatures can be used for rapid assessment of faunal biodiversity, akin to DNA barcoding and metabarcoding. We demonstrate that spectral signatures of individual, live fsh specimens can accurately capture species and clade‑level diferences in fsh coloration, specifcally among piranhas and pacus (Family Serrasalmidae), fshes with a long history of taxonomic confusion. We analyzed 47 serrasalmid species and could distinguish spectra among diferent species and clades, with the method sensitive enough to document changes in fsh coloration over ontogeny. Herbivorous pacu spectra were more like one another than they were to piranhas; however, our method also documented interspecifc variation in pacus that corresponds to cryptic lineages. While spectra do not serve as an alternative to the collection of curated specimens, hyperspectral data of fshes in the feld should help clarify which specimens might be unique or undescribed, complementing existing molecular and morphological techniques. Te biological sciences face two dire and disturbing issues: (1) increases in extinctions of animals across all con- tinents and oceans1–4, as well as (2) a shrinking pool of taxonomists trained to identify these organisms 5–7. -

The objective of this paper was to evaluate the parasitism by nematode larvae at three species of carnivorous fish in the Três Marias Reservoir, Brazil. It was verified 108 individuals of Pygocentrus piraya (Cuvier, 1819), 168 Serrasalmus brandtii Lütken, 1875, and 112 Cichla kelberi Kullander & Ferreira, 2006. A total of 59 individuals of nematode larvae were found in the three hosts and identified as third stage (L3 or infective larvae of definitive host) Spiroxys sp.. The parasitic indexes were more elevated in the P. piraya and S. brandtii, although the prevalence and abundance of Spiroxys sp. were higher in smaller specimens of S. brandtii. This may be explained since these juveniles feed some arthropods, that serve as intermediate hosts and fish parasitized by larvae of Spiroxys sp. while foraging. Just two individuals of C. kelberi were parasitized by Spiroxys sp. and this rare occurrence was shown to be accidental. This record adds to the current knowledge of this nematode’s life cycle and provides evidence that these carnivorous fish serve as paratenic hosts of Spiroxys sp. -

(August 2004) Craig Anthony Layman, B.S., University of Virginia; M.S., University of Virginia Chair of Advisory Committee: Dr. Kirk O. Winemiller Much of the world’s species diversity is located in tropical and sub-tropical ecosystems, and a better understanding of the ecology of these systems is necessary to stem biodiversity loss and assess community- and ecosystem-level responses to anthropogenic impacts. In this dissertation, I endeavored to broaden our understanding of complex ecosystems through research conducted on the Cinaruco River, a floodplain river in Venezuela, with specific emphasis on how a human-induced perturbation, commercial netting activity, may affect food web structure and function. I employed two approaches in this work: (1) comparative analyses based on descriptive food web characteristics, and (2) experimental manipulations within important food web modules. -

(August 2012) Sandra Bibiana Correa Valencia, B.S., Universidad del Valle; M.S., University of Florida Chair of Advisory Committee: Dr. Kirk Winemiller Diverse fish species consume fruits and seeds in the Neotropics, in particular in the lowland reaches of large rivers, such as the Amazon, Orinoco, and Paraná in South America. Floodplains of the Amazon River and its lowland tributaries are characterized by marked hydrological seasonality and diverse assemblages of frugivorous fishes, including closely related and morphologically similar species of several characiform families. Here, I investigated whether or not these fishes are capable of detecting fluctuations in food availability and if they are, how they adjust their feeding strategies.
