| 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... |

| Host-parasite interactions between crustaceans and six fish species (Psectrogaster falcata, Ageneiosus ucayalensis, Acestrorhynchus falcirostris, Hemiodus unimaculatus, Serrasalmus gibbus and Geophagus proximus) from a reservoir in eastern Amazon, northern Brazil, were investigated. Eight hundred and seventy-eight parasites belonging to three crustacean species, Excorallana berbicensis, Argulus chicomendesi and Ergasilus turucuyus, which parasitized the hosts’ mouth, gills and tegument, were collected from 295 fish and examined. High infestation levels were caused by E. berbicensis on the body surface of the hosts. Excorallana berbicensis showed aggregate dispersion, except in S. gibbus, while E. turucuyus showed random dispersion in A. falcirostris. The... |

| Abstract: The immune state is an essential component of survival as it directly influences physiological performance and health status. Variation in the leukocyte profile, a significantly increase in body temperature, and a detriment of the eco-physiological performance are among the possible consequences of an unhealthy state. In this study we analyse and discuss how field body temperature, preferred body temperature, the speed for sprint and long runs, locomotor stamina, and body condition can be affected by the immunological state (i.e. leukocyte profile) in a wild population of Liolaemus sarmentoi. Juveniles and adult males with a high percentage of eosinophils, basophils, and a low percentage of monocytes preferred higher body temperatures in a... |

| 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... |

| Studies with human beings and animals have shown that dietary conjugated linoleic acid (CLA) promotes changes in body structure, markedly, body fat reduction. This research aimed to assess the effect of CLA (60% of conjugated linoleic acid methyl ester, at the proportion of 1:1 of the 9, 11: 10, 12 isomers) on changes in body weight, subcutaneous tissue thickness, body fat mass and concentration of serum lipids (triacylglycerols, total cholesterol, LDL and HDL) in overweight dogs. Dogs of different breeds weighting 16.85±7.13 assigned in a randomized assay. Two types of diets were offered for 120 days: control (-CLA) and test (+CLA, 0.3%). There was no difference between control and test groups considering body weight and serum levels of triacylglycerols,... |

| 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... |

| 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... |

| Age and size at maturation appear as key parameters governing the dynamics of a population as they affect growth rate, fecundity, and survival. The expression of such life history traits is determined by genetic make-up and modulated by environmental factors mainly through phenotypic plasticity. Moreover, fishing, besides decreasing population size and changing demographic composition can alter allelic frequencies through fisheries-induced evolution by selecting for some particular traits. In the Bay of Biscay, a decreasing trend in both sardine body condition and size-at-age has recently been pointed out at the population level. The Probabilistic Maturation Reaction Norm (PMRN) approach was applied to help disentangle phenotypic plasticity and genetic... |

| 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... |

| Growing evidence suggests that telomeres, non-coding DNA sequences that shorten with age and stress, are related in an undefined way to individual breeding performances and survival rates in several species. Short telomeres and elevated shortening rates are typically associated with life stress and low health. As such, telomeres could serve as an integrative proxy of individual quality, describing the overall biological state of an individual at a given age. Telomere length could be associated with the decline of an array of physiological traits in age-controlled individuals. Here, we investigated the links between individuals' relative telomere length, breeding performance and various physiological (body condition, natural antibody levels) and life... |

| 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... |

| The change of animal biometrics (body mass and body size) can reveal important information about their living environment as well as determine the survival potential and reproductive success of individuals and thus the persistence of populations. However, weighing individuals like marine turtles in the field presents important logistical difficulties. In this context, estimating body mass based on body size is a crucial issue. Furthermore, the determinants of the variability of the parameters for this relationship can provide information about the quality of the environment and the manner in which individuals exploit the available resources. This is of particular importance in young individuals which growth quality might be a determinant of adult fitness.... |

| 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. |

| 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... |
