The aim of this study was to make the first characterization of the electrocardiogram (ECG) of the Burmeister porpoise (Phocoena sipinipinnis). A total of three ECGs were made in one, wild juvenile female (body weight = 32.5 kg, Lt = 1.45 m), temporarily held in captivity for rehabilitation at Mar del Plata Aquarium (Argentina). For ECG recordings,...
Article
The mammalian heart has been described as a highly evolutionarily conserved structure and the cardiovascular system allometry has been fully studied among many mammalian species, but few of these studies have been focused on marine mammals. Previously reported electrocardiogram (ECG) of anesthetized Southern sea lions (SSL; n = 13) and South Americ...

La ballena jorobada solía tener una presencia esporádica a lo largo de la costa de la Provincia de Buenos Aires (PBA), Argentina. A partir del año 2018 los avistamientos y varamientos han aumentado notablemente. El objetivo del presente trabajo es realizar una recopilación de los registros de ballena jorobada en la PBA, identificando: tendencias, e...

In this paper, we analyze the occurrence, abundance, and type of plastic debris (PD) present on the digestive tracts of 65 white croakers (Micropogonias furnieri) catches from Rio de la Plata Estuary System (RLPES). Eighty percent of individuals analyzed had ingested PD, of which 156 were thread-like plastics (FO = 83.9 %) and 30 were fragments (FO...

Male-only hauling grounds occur in close association to breeding colonies in several otariids. The occasional use of human-built infrastructure by these groups is also common. We observed permanent male aggregations of southern sea lions, Otaria flavescens, in urban contexts, such as two of the main fishing harbors in Argentina and investigated how...

The goal of this study was to characterize the Electrocardiogram (ECG) of anesthetized South American Fur Seals (SAFS). Nineteen wild SAFS females were anesthetized with isofluorane at Isla de Lobos (Uruguay). ECG recording was performed at ventral recumbence following standardized procedures. All animals showed normal sinus rhythm. Amplitude and d...

La Foca Leopardo (Hydrurga leptonyx) es una especie de pinnípedo antártico, con presencia ocasional en las costas argentinas, cuya histología está escasamente descripta, particularmente del corazón. El objetivo es presentar resultados preliminares del análisis histológico e histomorfométrico de corazón en dicha especie. Se tomaron muestras (n=9) de...

Existe limitada bibliografía sobre descripciones histológicas, en particular del corazón, de la Foca Leopardo (Hydrurga leptonyx), pinnípedo característico del continente Antártico. Esto se debe en gran parte a la dificultad de recolectar muestras de esta especie. El estudio de los componentes tisulares del corazón es importante para conocer adapta...

The goal of this study was to test transthoracic echocardiography as a method to characterize heart morphology and function in the southern sea lion (SSL) (Otaria flavescens) for health evaluation. Four clinically healthy captive SSLs (mean weight 110 ± 17.5 kg) were trained to be examined by transthoracic echocardiography at Mar del Plata Aquarium...
