“…The mean sodium levels were 139.6 ± 3.5 mequiv/l; Table 1 ), similar to those in reports for nesting sea turtles ( Deem et al , 2006 , 2009 ; Goldberg et al , 2011 ; Honarvar et al , 2011 ). Mean potassium levels were also similar to those reported in the literature for nesting sea turtles ( Deem et al , 2006 , 2009 ; Honarvar et al , 2011 ).…”

“…To our knowledge, this is the first study in the literature to report on biochemical reference intervals for nesting hawksbills in the South Atlantic Ocean. The triglyceride concentrations (1033 ± 202 mg/dl; Table 1 ) were significantly higher than those found in other sea turtle species ( Hasbún et al , 1998 ; Goldberg et al , 2011 ). Cholesterol levels (287 ± 42 mg/dl) fall within the range found by Hasbún et al (1998) for female green turtles in the United Arab Emirates (226.08 ± 123.06 mg/dl) and by Goldberg et al (2011) for nesting loggerheads in Brazil (247.75 ± 48.52 mg/dl).…”

Levels of triglycerides and cholesterol are likely to be elevated in nesting females due to vitellogenesis ( Derickson, 1976 ).…”

Ghrelin and leptin modulate the feeding behaviour of the hawksbill turtle Eretmochelys imbricata during nesting season

Female sea turtles rarely have been observed foraging during the nesting season. We investigated the levels of ghrelin, leptin and other physiological and nutritional parameters in nesting hawksbill sea turtles in Brazil. We found that levels of serum leptin (appetite-suppressing protein) decreased over the nesting season, while an increasing trend was observed in ghrelin (hunger-stimulating peptide). Both findings are consistent with the prediction that post-nesting females will begin to forage after the nesting season, , either during or just after their post-nesting migration.

“…The survival rate of rehabilitated animals once released back into the wild could be lower than that of wild turtles, further reducing overall success rates in terms of the potential for individuals to contribute to the population (Cardona et al 2012). Widespread rehabilitation of sick or injured turtles currently supplements other conservation efforts (IUCN 1995, Casal & Orós 2009, Goldberg et al 2011, Mestre et al 2014), but we still have a poor understanding of the conservation potential of rehabilitation in terms of numbers of healthy animals released (even without knowing their longer-term individual survival; Cardona et al 2012, Mestre et al 2014.…”

Wildlife rehabilitation can contribute to species conservation by releasing healthy individuals back into the wild and educating the public about threatening processes. Rehabilitation has substantial financial costs, however, and thus it is important to understand the success rates of these potential conservation management actions. We quantified the success rates for 1700 sea turtles admitted to rehabilitation facilities in Florida (USA) between 1986 and 2004. Rehabilitation success was low: 61.5% of turtles died in rehabilitation and only 36.8% were released back into the wild. A further 1.6% of turtles were maintained in captivity permanently due to the severe nature of their injuries. Most mortality occurred early during the rehabilitation process (within a few weeks), and successful rehabilitation often took several months to more than 3 yr. Loggerhead turtles Caretta caretta were most likely to survive rehabilitation, followed by Kemp's ridleys Lepidochelys kempii and green turtles Chelonia mydas; for all 3 species, larger individuals had an increased chance of successful rehabilitation. At face value, the low rates of rehabilitated turtles successfully released back into the wild may contribute only modestly to conservation in terms of contributing to population viability. However, many rehabilitation facilities provide important educational experiences that increase public awareness of the threats facing animals and highlight potential conservation solutions. Media coverage highlighting the release of rehabilitated animals further extends the conservation value of these efforts. Wildlife rehabilitation provides important direct benefits that, combined with social benefits, together may justify the expense and difficulty of rehabilitating individual animals.

“…McFadden et al (2014), found an average of 0.9 mg/dL (± 0.5), as well as Caliendo et al (2010) 1.7 mg/dL (±0.4), in this study, close values were found for hawksbill turtle 1.06 mg/dL (± 0.69). However, in loggerhead sea turtles, that have a different feed, mean uric acid values were found that ranged between 0.3 mg/dL and 1.2 mg/dL (mean 0.62 mg/dL ± 0.21) (GOLDBERG et al, 2011).…”

To obtain plasma biochemistry values, blood was collected for 47 nesting females of apparently healthy Eretmochelys imbricata sea turtles using sodium heparin as an anticoagulant. Blood samples were collected in April-Jun for two years (nesting season). Hematologic characteristics, including packed cell volume, white blood cell counts, red blood cell count and hemoglobin level; and plasma chemistry values, including creatinine, blood urea nitrogen, uric acid, triglyceride, total cholesterol, and glucose were measured. The data generated from this study may be useful for clinical assessment of health and disease of wild hawksbill sea turtles on nearshore habitats in the Gulf of Mexico, thus contributing to a conservation of this species. Keywords: Eretmochelys imbricata. Hematology. Plasma chemistry. Conservation. ResumoPara obter valores da bioquímica plasmática, foram coletadas amostras de sangue durante a desova de 47 tartarugas marinhas fêmeas aparentemente saudáveis da espécie Eretmochelys imbricata, utilizando heparina sódica como anticoagulante. Amostras de sangue foram coletadas durante dois anos entre os meses de abril e junho (época de nidificação). Mediu-se os parâmetros hematológicos (incluindo hematócrito, contagem de glóbulos brancos e vermelhos e nível de hemoglobina) e os valores da bioquímica plasmática (incluindo creatinina, ureia, ácido úrico, triglicérides, colesterol total e glicose). Os dados gerados a partir deste estudo podem ser úteis para a avaliação clínica de saúde e de doença em tartarugas-de-pente em habitats próximos ao litoral no Golfo do México, contribuindo para a conservação dessa espécie.

Abstract: Sea turtles are threatened to the point of extinction. The major goal of rehabilitating sick individuals is to eventually reintroduce them back into their habitat. In this way, they contribute to species preservation, as well as maintaining
