“…The frequency of juveniles stranded with ingested debris in Uruguay (South America) has been estimated at 73%, but reached 90% in Rio de la Plata -for both margins (Uruguay and Argentina/ GONZÁLEZ-CARMAN et al, 2014;TERYDA, 2015). Similarly, high frequencies of debris ingestion were observed along the Brazilian coast, and varied from ~60% to 100% in Rio Grande do Sul, southern Brazil (BUGONI et al, 2001;TOURINHO et al, 2010), 70% in Paraná state, southern Brazil (GUEBERT- BARTHOLO et al, 2011;GAMA et al, 2016), from 45% to 70% in São Paulo state, southeastern Brazil (BEZERRA, 2014;MENDES et al, 2015), ~60% from Rio de Janeiro to Espírito Santo state, southeastern Brazil (DiBENEDITTO; AWABDI, 2014;SANTOS et al, 2015) and 70% in Sergipe state, northeastern Brazil (SANTOS et al, 2015). It is interesting to note that the large frequencies of debris ingestion observed in Uruguay, Argentina and Brazil are a warning for the conservation of C. mydas, because these areas are considered to be part of an important migratory corridor in the southwestern Atlantic Ocean.…”

The green turtle Chelonia mydas as a marine and coastal environmental sentinels: anthropogenic activities and diseases Tartaruga-verde, Chelonia mydas, como sentinela do ambiente marinho e costeiro: atividades antrópicas e enfermidades AbstractThe green turtle Chelonia mydas is a widely distributed, slowly maturing species with a complex life cycle, using both oceanic and coastal environments. The species is exposed to different threats and is considered an environmental sentinel that indicates variation among, and the severity of hazards to marine ecosystems. This study aimed to describe both anthropogenic impacts, and infectious and parasitic diseases in C. mydas -including cases along the Brazilian coast -and implications for conservation. Bycatch is reported as the main threat to the conservation of this species, followed by debris ingestion, collisions with boats, dredging, and chronic environmental contamination. All of these impacts may directly or indirectly cause death, by facilitating contact with pathological agents and by increasing vulnerability to secondary diseases. The pathological agents associated with lesions include viruses, bacteria, fungi, protozoa, and helminths. Fibropapillomatosis is an example of a chronic disease characterized by cutaneous and visceral tumors that affects mostly juvenile C. mydas worldwide and is associated with the Chelonid herpesvirus 5. The bacterias Vibrio alginolyticus, Aeromonas hydrophila, and Pseudomonas fluorescens are found in the aquatic environment and among C. mydas lesions in various organs. Trematode adults and eggs of the family Spirorchiidae are also frequent in systemic cardiovascular diseases of C. mydas. The direct impacts of anthropogenic activities and diseases are synergistic and may affect the specie's health and conservation. Therefore, the monitoring and systematic diagnosing of diseases and causes of death -including necropsy, histopathology, and molecular exams -are necessary to assess a population's health, to support appropriate decisions of coastal management and to target future research topics that optimize C. mydas conservation. Key words: Bycatch. Conservation. Debris ingestion. Morbidity. Pathogenic agents. Sea turtle. ResumoA tartaruga-verde, Chelonia mydas, possui ampla distribuição geográfica, reprodução tardia e complexo ciclo de vida, habitando áreas costeiras e oceânicas. Devido a essas características, a espécie está exposta a diferentes tipos de ameaças e pode sinalizar sobre variações e a gravidade desses impactos ao longo do tempo no ecossistema, sendo considerada sentinela ambiental. Este trabalho teve por objetivo discorrer sobre relatos de atividades antrópicas impactantes e doenças infecciosas e parasitárias em C. mydas, com ênfase nas ocorrências no litoral brasileiro. A captura acidental em petrechos de pesca é uma das principais ameaças à conservação desses animais, assim como a ingestão de resíduos sólidos, colisão com embarcações, dragagens e bioacumulação de contaminantes químicos, os quais podem atuar diretament...

“…As a result, there is a rising concern about the negative effects that this form of pollution may have on sea life (Thompson et al, 2004;Moore, 2015). The levels of vulnerability and exposure of organisms to debris have been poorly explored (Moore, 2015), especially in the tropical oceans (Di Beneditto and Awabdi, 2014). Entanglements and ingestions are well documented for marine vertebrates such as fish, sea turtles, cetaceans, and seabirds (Hammer et al, 2012).…”

“…Debris ingestion has been documented in all sea turtle species and in all ocean basins, with an high variability of occurrence among different studies (Nelms et al, 2015;Schuyler et al, 2014a). Debris may be accidentally ingested if mixed with natural food (e.g., Di Beneditto and Awabdi, 2014), actively selected because similar to natural preys, like jellyfish (Hoarau et al, 2014;Schuyler et al, 2012;Schuyler et al, 2014b) or because encrusted by natural prey (Frick et al, 2009). Debris can obstruct, damage or cause inflammation of the digestive tract (Bjorndal et al, 1994;Di Beneditto and Awabdi, 2014;McCauley and Bjorndal, 1999;Vélez-Rubio et al, 2013), causing a reduced digestive capability and even death.…”

Even a small quantity of ingested debris can be lethal, at least in the green turtle Chelonia mydas (e.g., Bjorndal et al, 1994;Bugoni et al, 2001;Santos et al, 2015).…”
