Abstract: En el presente trabajo se analizó la estructura de tallas de ejemplares de tortuga pico de loro Lepidochelys olivacea, varados y capturados incidentalmente en las playas de Tumbes, Perú (3o38’9,5”S – 80o36’2,48”W y 3o57’21,3”S – 80o57’45,72”W), desde noviembre de 2006 a octubre de 2011. El área de estudio se dividió en tres zonas contiguas, limitadas por las quebradas más activas (Bocapán, El Rubio y Pe a Negra). Se registraron 39 ejemplares (74,4% varados y 25,6% capturados incidentalmente), cuyas tallas variaron de 45 a 75 cm LCC (62,5±5,7 cm LCC). El 64,1% correspondió a individuos sub-adultos (<65 cm LCC; n= 25). Espacialmente la mayor cantidad de registros ocurrieron en las zonas 3 y 2, en las cuales porcentajes superiores al 60% se consideraron sub-adultos; mientras que en la zona 1, el 83% fue adulto. Temporalmente en la época lluviosa se registró la mayoría de las observaciones (59%), en la cual el 78,3% de ejemplares se consideró sub–adulto; siendo mayor que en la época seca (43,8%). Las tallas presentaron diferencias significativas entre zonas y épocas climáticas. Se corroboró el patrón de distribución latitudinal por estados de madurez aparente (más adultos en el norte). La presencia del componente adulto indicaría que el litoral de Tumbes sería una potencial zona de anidamiento de L. olivacea, con mayores probabilidades de ovoposición en época seca, corroborada por los eventos de anidamiento recientes. In this paper we analyzed the size structure of Olive Ridley turtle Lepidochelys olivacea, from individuals stranded and incidentally caught in beaches of Tumbes, Peru (3o38’9.5”S – 80o36’2.48”W; 3o57’21.3”S – 80o57’45.72”W), since November 2006 to October 2011. The study area was divided into three contiguous areas, which were limited by the most active streams (Bocapan, El Rubio and Pe a Negra). There were 39 individuals (74.4% stranded and 25.6% caught incidentally), with sizes ranged from 45 to 75 cm CCL (62.5±5.7 cm CCL). 64.1% was considered sub-adult individuals (<65 cm CCL, n= 25). Spatially the largest number of records occurred in zones 3 and 2, in which percentages above 60% were considered sub-adults, while in zone 1, 83% was adult. Temporarily in the rainy season were registered the majority of the observations (59%), in which 78.3% of specimens was sub-adult, being higher than in the dry season (43.8%). Sizes showed significant differences between zones and climatic seasons. It was confirmed the latitudinal distribution pattern by apparent maturity stages (more adults in the north). Adults’ occurrences suggest that Tumbes coast w

Abstract: Con el objetivo de determinar la flora normal aerobia, cloacal y nasal de la tortuga lora (Lepidochelys olivacea ), entre los meses de julio y agosto del 2002,se colectaron muestras bacteriológicas de 45 quelonios aparentemente sanos,durante el desove en Playa Nancite,Parque Nacional Santa Rosa, Costa Rica, a través del uso de hisopos estériles que se introdujeron en la cloaca y en uno de los conductos nasales. De las muestras recolectadas se obtuvieron e identificaron un total de 99 aislamientos, incluyendo 10 grupos de Gram-negativos y 5 de Gram-positivos. De cada tortuga se obtuvo un promedio de 0.7 bacterias de la cloaca y 1.4 de las cavidades nasales. Las bacterias más frecuente halladas fueron Aeromonas spp.(13/45) y Citrobacter freundi (6/45) en la cloaca, y Bacillus spp. (32/45),Staphylococcus aureus (6/45)y Corynebacterium spp.(5/45)en las cavidades nasales. En este investigación, la flora microbiana de las tortugas lora resultó constituida por microorganismos potencialmente patógenos para el ser humano y las tortugas.

Abstract: Por su potencial como fuente alimenticia, se analizó la composición química de huevo de Lepidochelys olivácea en La Escobilla, Oaxaca, México. El Instituto de Ciencias del Mar y Limnología de la Universidad Nacional Autónoma de México proporcionó 250 muestras de huevo liofilizado de 25 tortugas, que se analizaron siguiendo métodos oficiales para humedad, cenizas, proteína, grasa, lípidos totales(LT) y análisis microbiológicos; además de ácidos grasos(AG) por cromatografía de gases, aminoácidos(AA), vitaminas y colesterol(col) por HPLC. Los resultados fueron los siguientes: (g/100g) humedad(4.7), cenizas(3.8), proteína(53.7) y grasa(47.4). AA esenciales (g aa/100g Proteína): Ile (4.4), Lys(6.6), Leu(7.4), Met+Cys (8.8), Phe+Tyr (10.8); retinol (340μg/100g), colecalciferol (5.9 μg/100g), tocoferol (8.6), tiamina (0.3) y riboflavina (1.1) (mg/100g). Y los de (LT), (AG) y (Col) se concentraron en tres grupos por peso de tortuga: (LT) (44.3-48.7-49.1g/100g), (Col) (518.4-522.5-728.7 mg/100g). Entonces se identificaron 17 AGSaturados, 8 AGMonoinsaturados y 11 AGPoliinsaturados. Los AGS más abundantes (mg/100g): C16:0 (485-1263), AGM: C16:1 (456-716), C18:1n-9c (904- 1754) y AGP: C20:4n-6 (105-217), EPA (48-103) y HA (97-189). También, existió diferencia significativa (Fisher, p<0.05) para (Col), AG totales, AGS, AGM, AGP y AG n-3 (EPA+DHA). No se detectó presencia de agentes microbiológicos. El huevo liofilizado de L. olivacea es una opción para el desarrollo de productos alimenticios por su proteína de alto valor biológico y ácidos grasos n-3.

Abstract: the variation in moisture and temperature was analized in the hatching of olive ridley turtle lepidochelys olivacea eggs, during the 1992-1993 season in ?el verde? beach (sinaloa, mexico). this variation was compared for different incubation environments (natural nests, corrals and polystyrene boxes). the results show that the average temperature was 33.6°c in natural nests, 32.8°c in corral and 32.1°c in boxes. moisture percentage fell between 59.6% to 23.4% as calculated by the weight method and for saturation of 22.9 ml g-1 to 8.8 ml g-1. hatching percentage was 67.9% in natural nests, 64.1% in corral and 46.9% in boxes. a granulometric study of sand showed differences in sand grain for nests areas. for this season the incubation average temperature was 32.7°c; for this reason, the hatchlings were females. the moisture levels registered in each incubation environment in this experiment apparently were not a determinant factor for the hatching success
