Fecal samples from 155 mantled howling monkeys (Alouatta palliata palliata) examined at Centro Ecologico La Pacifica, Guanacaste Province, Costa Rica, revealed 75 (48%) had parasitic infections. A sampling of nine howling monkeys from Santa Rosa National Park. Costa Rica indicated only one infected animal (11%). Only three of 19 (16%) spider monkeys (Ateles geoffroyi) also from Santa Rosa were infected. Controrchis biliophilus, Trypanoxyuris minutus, unidentified strongylid eggs and Isospora sp. oocysts were found. Three monkeys from La Pacifica died and were examined for adult helminths. They were infected with Ascaris lumbricoides, C. biliophilus and T. minutus.

© 2015 Elsevier Ltd.Sedimentological, ichnological and paleontological analyses of the Early Miocene uppermost Monte León Formation and the lower part of the Santa Cruz Formation were carried out in Rincón del Buque (RDB), a fossiliferous locality north of Río Coyle in Santa Cruz Province, Patagonia, Argentina. This locality is of special importance because it contains the basal contact between the Monte Léon (MLF) and the Santa Cruz (SCF) formations and because it preserves a rich fossil assemblage of marine invertebrates and marine trace fossils, and terrestrial vertebrates and plants, which has not been extensively studied. A ~90m-thick section of the MLF and the SCF that crops out at RDB was selected for this study. Eleven facies associations (FA) are described, which are, from base to top: subtidal-intertidal deposits with Crassotrea orbignyi and bioturbation of the Skolithos-Cruziana ichnofacies (FA1); tidal creek deposits with terrestrial fossil mammals and Ophiomorpha isp. burrows (FA2); tidal flat deposits with Glossifungites ichnofacies (FA3); deposits of tidal channels (FA4) and tidal sand flats (FA5) both with and impoverish Skolithos ichnofacies associated; marsh deposits (FA6); tidal point bar deposits recording a depauperate mixture of both the Skolithos and Cruziana ichnofacies (FA7); fluvial channel deposits (FA8); fluvial point bar deposits (FA9); floodplain deposits (FA10); and pyroclastic and volcaniclastic deposits of the floodplain where terrestrial fossil mammal remains occur (FA11).The transition of the MLF-SCF at RDB reflects a changing depositional environment from the outer part of an estuary (FA1) through the central (FA2-6) to inner part of a tide-dominated estuary (FA7). Finally a fluvial system occurs with single channels of relatively low energy and low sinuosity enclosed by a broad, low-energy floodplain dominated by partially edaphized ash-fall, sheet-flood, and overbank deposits (FA8-11). Pyroclastic and volcaniclastic materials throughout the succession must have been deposited as ash-fall distal facies in a fluvial setting and also were carried by fluvial streams and redeposited in both estuarine and fluvial settings. These materials preserve most of the analyzed terrestrial fossil mammals that characterize the Santacrucian age of the RDB's succession. Episodic sedimentation under volcanic influence, high sedimentation rates and a relatively warm and seasonal climate are inferred for the MLF and SCF section.Lateral continuity of the marker horizons at RDB serve for correlation with other coastal localities such as the lower part of the coastal SCF south of Río Coyle (~17.6-17.4Ma) belonging to the Estancia La Costa Member of the SCF.

A new species of polyclad flatworm from Papua New Guinea is described. It is found symbiotic in the ophiuroid Ophiothrix purpurea von Martens, 1867 (Echinodermata: Ophiuroidea). Apparently it belongs to the taxon Discoplana Bock, 1913 and can be distinguished from the six previously described Discoplana species by its very short ejaculatory duct and a penial papilla covered with a penial sheath, but without any true sclerotised structures such as a stylet or spines. The cladistic analysis of the Discoplana/Euplana species, based on morphological features and including two outgroups, reveals that all species of Discoplana, except D. pacificola, form a monophyletic taxon, that is not a synonym of Euplana Girard, 1893. Therefore the name Discoplana is conserved and the new species will be described as Discoplana malagasensis sp. nov. A key for the Discoplana/Euplana group is provided. In this key the biogeographical distribution and possible synonyms are given.

En el negocio de carne ovina argentina hay un desajuste en la cadena comercial, con alta informalidad y productos que no logran satisfacer las necesidades del mercado. A nivel de consumidor, hay una pérdida de hábito de consumo por desabastecimiento y la demanda se ajusta a productos genéricos. En este contexto, la industria formal tiene inconveniente para competir y desarrollarse. Por tanto, en el presente trabajo se planteo realizar un diagnóstico del subsistema de carne ovina Argentina, en general, y de La Pampa en particular para identificar las herramientas comerciales que permitan al Frigorífico Santa Isabel mejorar su posición en el mercado interno. Se realizó una investigación del tipo descriptiva en base a fuentes de información primaria y secundaria y se abordo metodológicamente utilizando las herramientas que brinda el plan de marketing. Se aplicaron conceptos de comercialización, estrategias de marketing y de análisis de los sectores industriales. Se observo que el sector de carne ovina de La Pampa se encuentra con bajo nivel de integración, desarrollo productivo y que Santa Isabel mantiene una posición competitiva deficiente frente a una industria nacional concentrada y desarrollada. Por otra parte, existe una demanda insatisfecha en la región de Cuyo que se proporciona como un mercado potencial para esta empresa. De acuerdo a las características de la demanda y del sector, se planteo una estrategia comercial centrada en la diferenciación. No obstante, será de suma importancia desarrollar tácticas tendientes a mejorar la coordinación del sistema de carne ovina en su conjunto.
