Condition corporelle et conséquences sur la plasticité des traits d’histoire de vie chez les petits pélagiques de Méditerranée ArchiMer
Brosset, Pablo.
Multiple changes have been described since 2008 in the Gulf of Lions ecosystem and particularly in small pelagic fish dynamic. In particular, the two main exploited species, i.e. anchovy (Engraulis encrasicolus) and sardine (Sardina pilchardus) are now smaller and in poor condition while a third species, the sprat (Sprattus sprattus) strongly increased in terms of biomass and abundance. This PhD thesis investigated these changes through the analysis of small pelagic fish body condition (i.e individual energy stores) variations, its causes and consequences. Anchovy and sardine body condition was optimal in 2005 and 2006 and decreased after 2008 to remain steady at low level since 2010. Moreover, older sardine have particularly displayed poor body condition...

Densité d'élevage chez la truite arc-en-ciel (Onchorynchus mykiss W.). Conséquences sur la qualité de la chair et l'état apparent ArchiMer
Sampietro Coloh, Sonia.
A triploid strain of rainbow trout (Onchorynchus mykiss) was reared in two experiments testing density effect on growth and flesh quality. Physiological index and corporal condition were also considered. Environmental  parameters were maintained identical between densities. Two fold 20, 50 and 80 Kg m·3 stocking densities were reared at 1.3% daily ration. No differences were found in fish growth neither in fish quality. A second experience compared two densities (50 and 110 kg m-3 ) and oxygen supplementation. Fish were fed ad libitum. Weight gain diminished at higher densities and oxygen supplementation had a favourable effect on fish growth. No differences were found in flesh quality parameters tested.

Development and validation of an objective method for the assessment of body condition scores and selection of beef cows for timed artificial insemination. Repositório Alice
PFEIFER, L. F. M.; CASTRO, N. A.; NEVES, P. M. A.; CESTARO, J. P.; SIQUEIRA, L. G. B..
The objectives of this study were to: 1) evaluate the relationship of the angle formed between the left and right sides of the rump with body condition score (BCS) in cattle; and 2) develop an objective tool to select cows for timed artificial insemination (TAI) based on their BCS. In Experiment 1, 801 lactating Nelore cows, 3?12 years old and weighing 400?625 kg were enrolled. All females were evaluated according to BCS (scale 1?5). In addition, the angle formed between both sides of the rump was measured in all cows with a goniometer. The relationship between BCS and the rump angle was analyzed by linear regression. There was a positive relationship between BCS and rump angle (P<0.0001). The linear regression equation was angle =77.76+9.94 x BCS;...

Evaluation of Three Mathematical Functions to Describe the Relationship Between Body Weight, Body Condition and Testicular Dimensions in Yankasa Sheep International Journal of Morphology
Yakubu,A; Musa-Azara,I. S.
Body size and testicular measurements have been found to be important parameters utilized in breeding soundness evaluation. The present study therefore, aimed at determining the relationship between body weight (BW), body condition score (BCS), testicular length (TL), testicular diameter (TD) and scrotal circumference (SC) in 120 extensively reared Yankasa rams (approximately 30 months old) using linear, quadratic and cubic predictive models. Coefficient of determination (R2), Adjusted R2, the estimate of Mallows' Cp, RMSE (Root mean squares error) and the parsimony principle (p=number of parameters) were used to compare the efficiency of the different models. Strong Pearson's correlation coefficients (r = 0.83-0.94; P<0.01) were found between BW, TL,...

Food in the Sea: Size Also Matters for Pelagic Fish ArchiMer
Queiros, Quentin; Fromentin, Jean-marc; Gasset, Eric; Dutto, Gilbert; Huiban, Camille; Metral, Luisa; Leclerc, Lina; Schull, Quentin; Mckenzie, David; Saraux, Claire.
Small pelagic fish are key components of marine ecosystems and fisheries worldwide. Despite the absence of recruitment failure and overfishing, pelagic fisheries have been in crisis for a decade in the Western Mediterranean Sea because of a marked decline in sardine size and condition. This situation most probably results from bottom-up control and changes in the plankton community toward smaller plankton. To understand such an unusual phenomenon, we developed an original and innovative experimental approach investigating the mechanisms induced by a reduction in the quantity and size of sardine prey. While experimentations offer the unique opportunity to integrate behavior and ecophysiology in understanding key demographic processes, they remain rarely...

Food limitation and low-density populations of sympatric hamster species in North China Naturalis
Xiong, W.; Liang, H.; Yu, X.; Cong, L.; Zhang, Z..
Although food has been proposed as a possible factor on population regulation of small mammals, evidence of food restriction in field conditions is still lacking. Food restriction is generally thought to occur in high-density years of oscillating populations of small mammals. By using two body condition indices (muscle protein concentration and cleaned carcass index), we investigated variations of body condition of the greater long-tailed hamster (Tscherskia triton) and the striped hamster (Cricetulus barabensis) in the Raoyang County of the North China Plain during a population decline- and low-phase from 1998 to 2003. Our laboratory experiments showed that food restriction reduced muscle protein concentration and cleaned carcass index of greater...

IGF-1 y actividad ovárica en la fase folicular tardía de cabras suplementadas con proteina no degradable en rumen en diferente condición corporal Colegio de Postgraduados
Guerra García, Minerva.
La influencia de la nutrición en la función ovárica se clasifica como “efecto estático”, “efecto dinámico” (Meza-Herrera et al., 2004) y “efecto agudo” (Scaramuzzi et al., 2006). Dichos efectos son mediados por cambios en los niveles de hormonas metabólicas y de la superfamilia de factores de crecimiento (Meza-Herrera et al., 2006), pero su importancia relativa y rutas de acción necesitan ser dilucidados (Martin et al., 2004). Se utilizaron 32 cabras de 19 meses de edad, F1 (AlpinoxNubia), sometidas a un periodo de adaptación de 40 días, registrando los pesos corporales y la condición corporal (Russel et al., 1969), al inicio y cada quince días en ayunas. A partir del día 40, la dieta consistió de heno de alfalfa molido y dos niveles de...

Maternal oxidative stress and reproduction: testing the constraint, cost and shielding hypotheses in a wild mammal ArchiMer
Viblanc, Vincent A.; Schull, Quentin; Roth, Jeffrey D.; Rabdeau, Juliette; Saraux, Claire; Uhlrich, Pierre; Criscuolo, François; Dobson, F. Stephen.
1.Oxidative stress has been proposed as a central causal mechanism underlying the life history trade-off between current and future reproduction and survival in wild animals. 2.Whereas mixed evidence suggests that maternal oxidative stress may act both as a constraint and a cost to reproduction, some studies have reported a lack of association between reproduction and maternal oxidative stress. 3.The oxidative shielding hypothesis offers an alternative explanation, suggesting that mothers may pre-emptively mitigate the oxidative costs of reproduction by increasing antioxidant defences prior to reproduction. 4.We tested the oxidative constraint, cost, and shielding hypotheses using a longitudinal field study of oxidative stress levels in a species that...

Negative effects of wind speed on individual foraging performance and breeding success in little penguins ArchiMer
Saraux, Claire; Chiaradia, Andre; Salton, Marcus; Dann, Peter; Viblanc, Vincent A..
Most effects of environmental and climate variability on predator life history traits and population dynamics result from indirect effects mediated through the food chain. There is growing evidence that wind strength might affect seabirds while foraging at sea. Here, we investigated the effect of wind speed on the foraging performance of a flightless marine predator, the little penguin (Eudyptula minor). To this end, we used satellite-derived wind data collected over 11 breeding seasons during which the daily attendance and body mass changes of more than 200 penguins breeding at Phillip Island (Victoria, Australia) were recorded by an automated penguin monitoring system. Over 17 363 foraging trips, we found that wind speed had important effects on foraging...

ARRAES, D. R. dos S.; TAVARES-DIAS, M..
Predation and alteration of microhabitats may represent high risk for nesting of Amazonian turtles. This study aimed at investigating the nesting and body parameters of neonates of Podocnemis unifilis in the Araguari River basin, State of Amapá, Brazil. The spawning sites of this turtle were monitored along the Falsino River (a region with two reserves) and in the urban area of the Porto Grande city along the Araguari River, from August to December 2011. A total of 180 nests were found and the nesting occurred from September to November, with prevalence in October. Eggs hatching occurred in December. The mean incubation period was 63.5 ± 5.2 days and the eggs hatching success was 25%. However, approximately 80% of the nests had suffered predation mainly by...

TANCREDO, K. R.; MARCHIORI, N. C.; ROUMBEDAKIS, K.; CERQUEIRA, V. R.; TAVARES-DIAS, M.; MARTINS, M. L..
The metazoan parasite fauna of snooks, Centropomus parallelus and Centropomus undecimalis, cultured in southern Brazil and parasite?s influence on the relative condition factor (Kn), are investigated. Snooks were parasitized by two species of gill monogeneans belonging to Rhabdosynochus (Diplectanidae) genus and by one endoparasitic digenean species Acanthocollaritrema umbilicatum (Acanthocollaritrematidae). Centropomus parallelus and C. undecimalis showed similar prevalence rates of Rhabdosynochus spp., but greater mean intensity and abundance rates were found in C. parallelus. On the other hand, there was no significant difference on prevalence, mean intensity and abundance of A. umbilicatumfor both hosts. The mean abundance of Rhabdosynochusspp....

Relationship among body condition at parturition, decrease of backfat thickness and weight during the lactation and the interval from weaning to oestrus of sows Braz. J. Vet. Res. Anim. Sci.
GUEDES,Roberto Maurício Carvalho; NOGUEIRA,Raimundo Hilton Girão.
The main objectives of this study were to verify the relationship among body condition at parturition, decrease of backfat thickness and weight during the lactation and the interval from weaning to oestrus of sows. It was performed with 10 gilts and 10 fifth, sixth and seventh parity Camborough sows. The average breeding age and weight of the gilts were respectively 231 days and 149.5 kg. During lactation all females were fed a wet diet (3.34 Mcal/kg, 17% CP), ad libitum. The average daily food consumption was 5.233 for gilts and 5.721 kg for multiparous sows. Ultrasonic measurements of backfat at the P2 site were recorded on day 6 before and days 2, 7, 14, 21 and 25 after parturition. Body weight was recorded on the same dates, except the day before...
