Maternal exercise could be a potent modifier of maternal behavior (MB). Regular physical exercise is widely recommended but is frequently modified during pregnancy, so we tested whether stopping, starting, reducing, or maintaining the running intensity during pregnancy can protect dams from MS-induced behavior and memory alterations, as well as influence mother-pup bonding. Female rats were divided into six groups: non-exercised mothers that were not submitted to MS (Control); non-exercised mothers submitted to MS (MS); mothers that ran (physical exercise) only before pregnancy and were submitted to MS (PRE+MS); mothers that started to run at the beginning of pregnancy submitted to MS (GEST+MS); mothers that ran before pregnancy and reduced the running intensity during pregnancy and were submitted to MS (RED+MS); and, mothers that ran at the same intensity before and during pregnancy and were submitted to MS (EQUAL+MS). We performed MS from PND 1 to 10, three hours per day. We assessed MB for 30 min after MS from PND 1 to 5. We assessed object recognition (OR) memory before and during pregnancy and after weaning. We assessed maternal preference (MP) one week after weaning. We measured hippocampal lipid peroxidation and catalase levels 24 h after the ending of all tests. PRE+MS leads to detraining and memory deficits at the end of pregnancy and after weaning. MS, PRE+MS, and RED+MS increased the time spent in the nest. GEST+MS mothers preferred contact with their male and female offspring after weaning. GEST+MS prevents OR deficit after weaning. PRE+MS showed increased lipid peroxidation after weaning.

Here we examine how the BTBR mouse responds to various non-photic treatments. Because activity levels can modulate the FRP, we first examined if the shorter FRP of BTBR mice resulted from their higher activity levels. While overall activity was lower when housed without a running wheel, this did not significantly alter their FRP. When housed in constant light, exposure to a 6 h dark pulse improved the quality of the locomotor rhythms for both BTBR and C57 mice. BTBR mice had significantly smaller phase shifts to midday treatments with either a 3 h sleep deprivation procedure or an injection of the serotonin 1A/7 receptor agonist (±) 8-OH-DPAT than did the comparison C57BL/6J strain. However, BTBR mice did exhibit larger responses to midday refeeding pulses following 18 h food deprivation.

The timing of host immune responses and concomitant changes in behavior may be jointly underpinned by an increase in glucocorticoid hormones. The temporal and causal links between these interrelated responses to infection remain equivocal in many host-pathogen systems. Here, using a fungal pathogen implicated in global amphibian declines, <em>Batrachochytrium dendrobatidis</em> (<em>Bd</em>), we examined sublethal consequences of infection in the Cuban tree frog (<em>Osteopilus septentrionalis</em>). Specifically, we tracked changes in the neuroendocrine stress response by measuring urinary corticosterone (CORT) metabolites as well as immunological activation via neutrophil/lymphocyte (N/L) ratios over three consecutive rounds of <em>Bd</em> exposure. Additionally, we measured both exploratory behavior and activity level in open field arenas to evaluate whether infection-mediated changes in behavior and stress physiology coincided. Pathogen-exposed individuals began testing positive for <em>Bd</em> after two rounds of exposure. After the third exposure, <em>Bd</em>-positive frogs had higher CORT levels compared to control frogs. While infection load was not associated with N/L ratio, CORT concentrations showed a negative correlation with N/L ratio, suggesting a link between endocrine activity and immune regulation. Furthermore, there were no differences in exploratory behaviors or activity levels between control and <em>Bd</em>-exposed frogs. The lack of a relationship between N/L ratios and infection load may indicate a lag between neuroendocrine and immunological responses in this host-parasite system. This is further supported by the delayed increase in CORT levels only after three rounds of pathogen exposure. Alternatively, the lack of a relationship may be due to the immunosuppressive capability of <em>Bd</em>.
