Is Haemoproteus gabaldoni a valid species? An approach from morphology and molecular tools applied to parasites of Anseriformes

Acta Tropica (2022)

Angie D. González Ingrid Astrid Lotta-Arévalo Gustavo Andrés Fuentes-Rodríguez Jhon Macías-Zacipa Luz Dary Acevedo-Cendales

Currently, there are three recognized species of haemoproteids infecting Anseriformes: Haemoproteus nettionis, H. macrovacuolatus, and H. greineri. Unfortunately, genetic information associated with a morphotype is available only for H. macrovacuolatus. We recently found a parasite morphologically compatible with Haemoproteus gabaldoni, a species Bennet (1993) described in a Cairina moschata (Muscovy duck) from Venezuela. This species was synonymized to H. nettionis by Valkiūnas (2005), arguing not enough morphological differentiation between them; it was said that H. greineri could be as well a synonym of H. nettionis. In this study, we aimed to provide evidence to determine if Haemoproteus gabaldoni is a different species of H. nettionis and help to clarify other species status. We first performed morphological and morphometrical analyses and compared this information against the parahapantotypes of H. greineri, H. gabaldoni and material diagnosed as H. nettionis provided by the International Reference center for Avian Haematozoa (IRCAH), and H. macrovacuolatus from the Host-Parasite Relationship Study Group (GERPH, in Spanish Grupo de Estudio Relación Parásito Hospedero) biological collection. We used Principal Component Analysis (PCA) of dimensionless standard morphometrical variables from gametocytes. Furthermore, we amplified a small fragment of cytochrome b (cyt b) to compare the sequence with information in GenBank and Malavi through phylogenetic analyses and haplotype networks. PCA analyses revealed the presence of three distinct groups in the samples studied, supported in the morphological traits of each parasite species analyzed; phylogenetic analyses grouped parasite lineages separately according to the host and continent of provenance. Such results indicate that, H. gabaldoni, is a different species from H. nettionis. One more time, it is demonstrated the importance of linking barcode surveys to morphological studies. Finally, it is highlighted the importance of biological collections as repositories of worldwide biodiversity.

Análisis del branded content de la marca Mattelsa en Instagram para caracterizar a los Millennials

instname:Universidad Autónoma de Occidente (2019)

Angie D. González Valentina Cajiao Arcila

Los formatos de publicidad estan en constante evolucion, asi como el consumo tanto de medios como de publicidad se ha ido acoplando de acuerdo a las necesidades que el mercado Millennial demanda, ya que el contenido que estos consumen debe ser acorde a sus preferencias. El objetivo de este estudio es caracterizar a los Millennials a traves del analisis del branded content en Instagram de la marca Mattelsa. Con este fin, la pregunta de investigacion es la siguiente: ?Cuales son las caracteristicas del Millennial que consume los contenidos de Instagram de la marca Mattelsa? En este contexto, la caracterizacion de dicho consumidor es de suma importancia ya que nos permite dejar en evidencia el tipo de contenidos con los que sienten afinidad los Millennials. La pregunta de investigacion se respondera a traves de una matriz de analisis que implica diferentes variables con las cuales los Millennials actuan en las plataformas digitales, en este caso la red social Instagram, especificamente de la marca Colombiana Mattelsa

Biodiversidad 2015. Reporte de Estado y Tendencias de la Biodiversidad Continental de Colombia

Andrés R. Acosta‐Galvis Mauricio Aguilar-Garavito Daniel Amariles Paula Amaya Ángela Andrade

El proposito de este documento es fortalecer la capacidad de agentes publicos y privados para la aplicacion de la PNGIBSE, que constituye en si misma una apuesta de interfaz entre ciencia, politica y sociedad en la perspectiva de construir sostenibilidad en el desarrollo. Ademas de ello, representa un insumo para el seguimiento a los compromisos del pais frente a convenios e iniciativas internacionales (CDB, IPBES, OCDE), asi como un mecanismo pedagogico para generar interes, conciencia y apropiacion de las diferentes dimensiones de la biodiversidad del pais. En esta oportunidad, el reporte avanza en el desarrollo de nuevas infografias vinculadas con diferentes fuentes de informacion que garantizan la calidad de los datos con los que se propone y representa el estado de la biodiversidad y de su gestion en Colombia. Incluye como novedad la presentacion de material en portal web dedicado (reporte.humboldt.org.co), de manera que todas las personas puedan apropiarse e interactuar con el contenido de manera mas efectiva. La perspectiva es construir un modelo en tiempo real del trabajo que se desarrolla en el pais para conocer, proteger, utilizar o restaurar su biodiversidad y servicios ecosistemicos, promoviendo la apropiacion de todos los ciudadanos e instituciones en la tarea. Biodiversidad 2015, es evidente, aun no esta en capacidad de dar cuenta de todos los procesos de gestion de biodiversidad que se dan en Colombia, liderados por multiples actores y a todas las escalas. Paulatinamente esperamos poder abrir el espacio para incrementar la visibilidad de todas y cada una de las iniciativas que se adelanten, a sabiendas de que la posibilidad de encontrar nuevas respuestas y mejores practicas no depende del Instituto ni de ninguna instancia en particular, sino de la capacidad colectiva de aprendizaje. Asi, esperamos que este nuevo paso en la construccion de un producto colaborativo sea del interes de todos y nos permita avanzar en esa direccion. reporte.humboldt.org.co

Avian hemoparasites distribution in an altitudinal transect in Colombia

The Biologist (2012)

Estela Nubia Matta Angie D. González Ligia Inés Moncada

The hemoparasites present in birds from the Otun river high basin, were studied in four locations forming an altitudinal transect between 2100 and 3950 masl. The birds were captured using mist nets from April 2010 to January 2012, totaling 7253 hours-net sample effort making 783 captures that represent 100 species from 21 families. Blood samples were collected by distal nail cut or brachial vein puncture, for each bird three blood smears were made, and diagnosed by light microscopy. The genus: Plasmodium, Haemoproteus, Leucocytozoon and Trypanosoma were determined, with overall frequency of 6%. At 2400 masl the higher hemoparasite frequency (18%) was founded, decreasing to 2% at 3950 masl where only parasites belonging to the Leucocytozoon genus were founded. These genus infection frequencies varied according altitude and host family and species. The species: Hemispingus atropileus, Hemispingus superciliaris, Zonotrichia capensis, Turdus fuscater, Atlapetes pallidinucha, Atlapetes albinucha, Arremon brunneinucha, Anisognatus somptuosus, Dacnis cayana were the most frequently infected. The altitude effect on hemoparasite distribution is associated with abiotic conditions that could affect vectors and birds distribution, because, the parasite, host, vector relationship requires the sympatric and synchronic circulation of its components. Worldwide, this study is pioneer at this altitude.

Identification ofPlasmodium (Haemamoeba) lutzi(Lucena, 1939) fromTurdus fuscater(Great Thrush) in Colombia

Journal of Parasitology (2013)

Juan S. Mantilla Nubia E. Matta M. Andreína Pacheco Ananías A. Escalante Angie D. González

This study reports a broadening of the altitudinal range and a new host for Plasmodium (Haemamoeba) lutzi in Colombia. The study was conducted in the city of Bogotá, located in the Eastern Cordillera of Colombia at 2,560 m asl (meters above sea level) with an average annual temperature of 15 C. In total, 156 specimens of birds belonging to 25 species and 14 families were captured using mist nets. The blood samples were collected through venipuncture and analyzed by light microscopy. Plasmodium (H.) lutzi was only found in 2 individuals of Turdus fuscater (Great Thrush). This parasite has previously been reported in Aramides cajaneus (before: Aramides cajanea) (Grey-Necked Wood Rail), a bird found in the lowlands of Brazil, Venezuela, and Colombia. This finding provides evidence for a broad host range for P. lutzi that include 2 different orders, Gruiformes and Passeriformes, and also altitudinal expansion of its distribution. The blood stages were compared with the parasite's original descriptions, and the sequence of the parasite's mitochondrial genome (mtDNA) confirms that P. lutzi is a sister taxa of Plasmodium relictum, as previously proposed.
