Top view of DR1/DR2 double riffle, each section contains a spawning ground made up of eight gravel-filled trays, a rest area. The "double riffle" was designed to accommodate two groups from 25 to 50 specimens of broodstock in strictly identical conditions. The spawning grounds are equipped with waterproof, motion-sensing cameras with infrared night vision, connected to a 1000 Gb recorder. The diurnal and nocturnal activities of the two groups can therefore be simultaneously recorded over a long period. in Reproduction of Zingel asper (Linnaeus, 1758) in controlled conditions: an assessment of the experiences realized since 2005 at the Besançon Natural History Museum

Fig. 2. Anti-tumour necrosis factor (TNF) activity in tick salivary glands during feeding. Salivary gland extract (SGE) was prepared from females of Ixodes ricinus (Linnaeus, 1758) either unfed (day 0) or fed for 2, 4, 6 and 8 days. Various concentrations of SGE protein were preincubated for 1.5 h with 2 ng/ml of mouse recombinant TNF before the cytokine ELISA was performed. PBS instead of SGE was added into negative control. Results are presented as the mean ± SD of triplicate wells. *The difference between saliva-treated and untreated group was signif- icant at P <0.05.

Dataset for the study Sensitive period for the plasticity of alpha activity in humans
<p>Raw EEG data in european data format (EDF) format. Descriptive and clinical data of the subjects in textual tab delimited format. Columns report for each subject: group (blind/severely impaired, BSI or sighted, S), code, gender, age expressed in decimal years, age bin, degree of visual impairment, diagnosis, motor coordination impairment classification (MCI, 1 = not impaired, 2 = impaired), and hypotonia classification (1 = not impaired, 2 = impaired). NA correspond to undefined classification.</p> <p>Visual experience is crucial for the development of neural processing. For example, alpha activity development is a vision-dependent mechanism. Indeed, studies report no alpha activity is present in blind adults. Nevertheless, studies have not investigated the developmental trajectory of this activity in infants and children with blindness. Here, we hypothesize that the difference in neural activity of blind compared to sighted subjects is: absent at birth, progressive with age, specifically occipital and linked to a gradual motor impairment. Therefore, we consider spectral power of resting-state EEG and its association with motor impairment indices, in blind subjects and in sighted controls between 0 and 11 years of age. Blind subjects show posterior alpha activity during the first three years of life, although weaker and slower maturing compared to sighted subjects. The first great differentiation between blind and sighted subjects occurs between 3 and 6 years of age. Starting in this period, reduced alpha activity increases the probability of motor impairment in blind subjects, likely because of impaired perception/interaction. These results show that visual experience mediates the neural mechanisms generating alpha oscillations during the first years of life, suggesting that it is a sensitive period for the plasticity of this process.</p>
Data from: Immune challenge reduces daily activity period in free-living birds for three weeks
<p>Non-lethal infections are common in free-living animals and the associated sickness behaviours can impact crucial life-history trade-offs. However, little is known about the duration and extent of such sickness behaviours in free-living animals, and consequently how this affects life-history decisions. Here, free-living Eurasian blackbirds <em>Turdus merula</em> were immune-challenged with lipopolysaccharide (LPS) to mimic a bacterial infection, and their behaviour was monitored for up to 48 days using accelerometers. As expected, immune-challenged birds were less active than controls within the first 24 hours. Unexpectedly, this reduced activity remained detectable for 20 days, before both groups returned to similar activity levels. Furthermore, activity was positively correlated with a pre-experimental index of complement activity, but only in immune-challenged birds, suggesting that sickness behaviors are modulated by constitutive immune function. Differences in daily activity levels stemmed from immune-challenged birds resting earlier at dusk than control birds, while activity levels between groups were similar during core daytime hours. Overall, activity was reduced by 19% in immune-challenged birds and they were on average almost 1 hour less active per day for 20 days. This unexpected longevity in sickness behaviour may have severe implications during energy-intense annual-cycle stages (e.g., breeding, migration, winter). Thus, our data help to understand the consequences of non-lethal infections on free-living animals.</p>
Water loss, not overheating, limits the activity period of an endothermic Sonoran Desert bee
<ol> <li>Desert animals must manage the physiological stresses of heat and desiccation; evaporative heat loss mitigates overheating but exacerbates water stress. Small endothermic flying insects may be particularly vulnerable to overheating and water stress as a result of high surface area to volume ratios, but we lack quantitative understanding of the relative magnitude of these abiotic stressors in flying desert invertebrates, despite their ecological importance.</li> <li>During the hottest and driest weeks of the year, many thousands of males of the Sonoran Desert digger bee (<em>Centris</em> <em>caesalpiniae</em>) flew near-continuously at elevated thorax temperatures for hours at mating aggregation sites, while occasionally fighting other males and digging for females.</li> <li>To determine whether incapacitating high temperatures or water loss limited the activity period of male <em>C. caesalpiniae</em>, we assessed wet and dry body mass and water content through the activity period, crop volume and sugar content, microclimate selection, water loss rate and metabolic water production during flight, critical water content, and maximum critical temperature.</li> <li>Body masses and sizes of males declined through the morning and smaller bees had higher fractional water contents. Crop volume and sugar content did not vary through the day or with bee size.</li> <li>Maximum critical temperature during flight was 51°C, similar to those measured for other bees, and well above temperatures reached in the field, suggesting that avoidance of over-heating does not limit activity in this desert bee.</li> <li>The critical water content of <em>Centris</em> bees averaged 50%. Measures of net water loss rate indicated that males approached lethal water loss limits within four hours, suggesting that desiccation tolerance limits activity. Remarkably, male <em>C. caesalpiniae </em>were not observed to forage at floral or water sources during the activity period, and foraged over multiple days, suggesting selection to maintain reproductive success and that these males have a mechanism to rehydrate when not at the mating aggregation.</li> </ol>
