“…TBT is an organotin compound used commonly as a biocide in antifouling paints applied to boats and marine structures and was historically found at high concentrations in aquatic environments ( Mcallister and Kime, 2003 ). Though the International Maritime Organization banned the use of TBT in anti-fouling paints in 2008 ( Showalter and Savarese, 2004 ; Gipperth, 2009 ; IMO, 2019 ), which lead to reduced environmental levels ( Liang et al, 2017 ) and wildlife recovery ( Jones and Ross, 2018 ), recent reports identify spikes in TBT levels (µg/g) in coastal areas off of Latin America, Norway, and Panama ( Batista-Andrade et al, 2018 ; Schoyen et al, 2019 ; Castro et al, 2021 ) and TBT-based paint is still sold ( Uc-Peraza et al, 2022 ), suggesting continued exposure. TBT is not readily biodegradable ( Mcallister and Kime, 2003 ) and, once ingested, bioaccumulates and crosses the blood brain barrier, concentrating in areas of the brain that receive sensory inputs ( Roulea et al, 2003 ).…”

The Role of Estrogen and Thyroid Hormones in Zebrafish Visual System Function

Visual system development is a highly complex process involving coordination of environmental cues, cell pathways, and integration of functional circuits. Consequently, a change to any step, due to a mutation or chemical exposure, can lead to deleterious consequences. One class of chemicals known to have both overt and subtle effects on the visual system is endocrine disrupting compounds (EDCs). EDCs are environmental contaminants which alter hormonal signaling by either preventing compound synthesis or binding to postsynaptic receptors. Interestingly, recent work has identified neuronal and sensory systems, particularly vision, as targets for EDCs. In particular, estrogenic and thyroidogenic signaling have been identified as critical modulators of proper visual system development and function. Here, we summarize and review this work, from our lab and others, focusing on behavioral, physiological, and molecular data collected in zebrafish. We also discuss different exposure regimes used, including long-lasting effects of developmental exposure. Overall, zebrafish are a model of choice to examine the impact of EDCs and other compounds targeting estrogen and thyroid signaling and the consequences of exposure in visual system development and function.

“…Protected areas, such as national parks, are created for conservation purposes and seek to protect the local biodiversity. Recent studies have demonstrated chemical impacts within protected zones severely threatening local species despite low contaminant concentrations [68,69]. Considering that water quality parameters adopted worldwide were developed based on urban areas, those limits may fail to assure environmental protection to pristine zones [68].…”

Since 2013, there has been an increase (>23%) in naval traffic using maritime routes and ports on the coastal fringe of Santa Marta, Colombia. Of major concern, and described by several studies, is the relationship between maritime traffic and coastal contamination. This study proposed a maritime traffic indicator considering the simultaneous effects of several relevant measurements of water quality parameters to estimate the impact of naval activity. The approach involved developing a model including the number of vessels, hull length, and permanence time in berths. In addition, water quality variables, considering climatic seasons, were used to verify association with maritime traffic and touristic activities. The high concentrations of total coliforms (TC) and dissolved/dispersed petroleum hydrocarbons in chrysene equivalents (DDPH) reported by the International Marina of Santa Marta (SM) were affected by the local anthropic activities, including tourism, naval traffic, and urban wastewater discharges. Moreover, our results suggest the occurrence of multiple chemical impacts within Tayrona National Natural Park (PNNT) affecting conservation goals. The estimation of the maritime traffic indicator proposed in this study may be an easy and more complete tool for future studies evaluating the impact of naval activities on environmental quality.

“…En reconocimiento a su importancia, las islas fueron designadas Patrimonio Cultural de la Humanidad en 1976, Reserva de la Biosfera Archipiélago de Colón en 1984 y sitio Ramsar en 2001 (Muñoz-Barriga y Maldonado Pérez, 2020; Ishwaran, 2010;Castro et al, 2021). Las islas Galápagos albergan una diversa gama de ecosistemas, creados no solo por las condiciones oceanográficas únicas sino también por su aislamiento y origen volcánico (Bastille-Rousseau et al, 2019;Edgar et al, 2010;Rivas-Torres et al, 2018).…”

Los censos son una fuente primaria más importante y amplia de información estadística, dada su periodicidad se puede evaluar su evolución, además los censos son un instrumento con un conjunto de variables a las que se las transforma en indicadores de cumplimiento de los objetivos de desarrollo sostenible a nivel nacional, provincial, cantonal, etc. los objetivos planteados fueron: i) Caracterizar las condiciones sociodemográficas en las islas Galápagos a partir de datos censales, ii) Identificar los indicadores de los Objetivos de Desarrollo Sostenible (ODS) en el marco de la Agenda 2030, desagregado por área urbana y rural a partir del registro censal. La zona de estudio fueron las islas Galápagos, subdividida en los tres cantones y segmentada en zona urbana y rural. Se utilizó el programa REDATAM versión 7, creado por Centro Latinoamericano y Caribeño de Demografía, y se utilizó los datos censales del 2015 de Galápagos. Se identificaron ocho variables demográficas y dos indicadores de vivienda: 1) población que dispone de servicios de suministro de agua y 2) población con acceso a la electricidad. En la pirámide poblacional de los tres cantones Isabela, San Cristóbal, Santa Cruz. Se identificaron dinámicas similares, donde existen potenciales procesos migratorios en la población joven; la tasa de población en Santa Cruz es de 130 hab/km2, mayor a las existentes en San Cristóbal e Isabela, entre los tres cantones la tasa promedio de hijos por mujer es de 0,32. Existen 13 tipologías de viviendas distribuidas de manera heterogénea en el área de estudio, la proporción de viviendas que disponen de agua potable gestionados de manera segura es mayor en el sector urbano que el rural y Santa Cruz es el área de mayor desarrollo que los otros cantones, mientras que en la proporción de la población que tiene acceso a la electricidad en el sector rural a nivel cantonal 4.7 veces menor que el sector urbano. Se identificaron puntos críticos para el desarrollo del sector urbano y rural de Galápagos, siendo una fortaleza para la toma de decisiones de los gestores políticos a nivel cantonal y sectorial.
