Data from: Cascading effects of thermally-induced anemone bleaching on associated anemonefish hormonal stress response and reproduction
Organisms can behaviorally, physiologically, and morphologically adjust to environmental variation via integrative hormonal mechanisms, ultimately allowing animals to cope with environmental change. The stress response to environmental and social changes commonly promotes survival at the expense of reproduction. However, despite climate change impacts on population declines and diversity loss, few studies have attributed hormonal stress responses, or their regulatory effects, to climate change in the wild. Here, we report hormonal and fitness responses of individual wild fish to a recent large-scale sea warming event that caused widespread bleaching on coral reefs. This 14-month monitoring study shows a strong correlation between anemone bleaching (zooxanthellae loss), anemonefish stress response, and reproductive hormones that decreased fecundity by 73%. These findings suggest that hormone stress responses play a crucial role in changes to population demography following climate change and plasticity in hormonal responsiveness may be a key mechanism enabling individual acclimation to climate change.
Evaluation of assisted reproductive technology treatment outcomes based on stimulation dosages and anti-mullerian hormone levels
<p><span>Background: </span><span>Serum concentrations of anti-mullerian hormone (AMH) correlate with ovarian response during assisted reproductive (ART) treatment cycles. This prospective study was attempted to evaluate the selection of ovarian stimulation protocols based on serum AMH levels in patients and its impact on the results of ART.</span></p> <p><span>Results</span></p> <p><span>According to the AMH levels, majority of the patients were normal responders (52.4%) followed by high responders (29.8%) and low responders (17.8%). The average FSH, HMG per day and number of days HMG required was found to be significant among the different responders. Further, retrieval rate and blastulation rate was found to be significant among the different responders. A positive correlation was found between AMH and number of oocytes retrieved and number of oocytes successfully fertilized and it was found to be significant. In addition, there was a significant inverse relationship between AMH levels and age.</span></p> <p><span>Conclusion</span></p> <p><span>The study outcome reveals that retrieval rate, maturation rate, fertilization rate, embryo utilization rate and blasturation rate were higher among the high responders as compared to low responders. Thus, proper increase in dosages of ovarian stimulation protocol is required among the low responders to achieve quality embryos. </span></p>

Data from: Pleiotropic effects of juvenile hormone in ant queens and the escape from the reproduction-immunocompetence trade-off
The ubiquitous trade-off between survival and costly reproduction is one of the most fundamental constraints governing life-history evolution. In numerous animals, gonadotropic hormones antagonistically suppressing immunocompetence cause this trade-off. The queens of many social insects defy the reproduction-survival trade-off, achieving both an extraordinarily long life and high reproductive output, but how they achieve this is unknown. Here we show experimentally, by integrating quantification of gene expression, physiology and behaviour, that the long-lived queens of the ant Lasius niger have escaped the reproduction-immunocompetence trade-off by decoupling the effects of a key endocrine regulator of fertility and immunocompetence in solitary insects, juvenile hormone (JH). This modification of the regulatory architecture enables queens to sustain a high reproductive output without elevated JH titres and suppressed immunocompetence, providing an escape from the reproduction-immunocompetence trade-off that may contribute to the extraordinary lifespan of many social insect queens.
Juvenile hormone pathway in honey bee larvae: a source of possible signal molecules for the reproductive behavior of Varroa destructor
<p>The parasitic mite <i>Varroa destructor </i>devastates honey bee (<i>Apis mellifera</i>) colonies around the world. Entering a brood cell shortly before capping, the <i>Varroa</i> mother feeds on the honey bee larvae. The hormones 20-hydroxyecdysone (20E) and juvenile hormone (JH), acquired from the host, have been considered to play a key role in initiating <i>Varroa</i>'s reproductive cycle. This study focuses on differential expression of the genes involved in the biosynthesis of JH and ecdysone at 6 time points during the first 30 hours after cell capping in both drone and worker larvae of <i>A. mellifera</i>. This time frame, covering the conclusion of the honey bee brood cell invasion and the start of <i>Varroa</i>'s ovogenesis, is critical to the successful initiation of a reproductive cycle. Our findings support a later activation of the ecdysteroid cascade in honey bee drones compared to worker larvae, which could account for the increased egg production of <i>Varroa</i> in <i>A. mellifera</i> drones. The JH pathway was generally downregulated confirming its activity is antagonistic to the ecdysteroid pathway during the larva development. Nevertheless, the genes involved in JH synthesis revealed an increased expression in drones. The upregulation of <i>jhamt</i> gene involved in methyl farnesoate (MF) synthesis came into attention since the MF is not only a precursor of JH but it is also an insect pheromone in its own right as well as JH-like hormone in Acari. This could indicate a possible kairomone effect of MF for attracting the mites into the drone brood cells, along with its potential involvement in ovogenesis after the cell capping, stimulating <i>Varroa</i>'s initiation of egg laying.</p>
Figure 2 in Intragonadal evaluation of sexual steroid hormones during three reproductive events in two species of Peromyscus (Rodentia: Cricetidae)
Figure 2. Production and biotransformation profiles in four selected SSH of the ∆4 pathway by reproductive event in two species of Peromyscus. Mean intraovarian concentrations of sexual steroid hormones ([SSH]: progesterone, P4; androstenedione, A, testosterone, T; estradiol, E2) were assessed in free-living, adult females of P. melanotis (A) and P. difficilis (B), during estrous cycle (PRO, proestrus; EST, estrus; MET, metestrus; DIE, diestrus), pregnancy (early gestation, G1; late gestation, G2), and overall lactation. Bars depict mean [SSH] and vertical whiskers the respective standard errors; arrows signal which [SSH] had significant differences with others; when more than one [SSH] was statistically different in ANOVA analyzes, horizontal lines were added and arrows below and above them signal the respective [SSH]; number of asterisks indicate degree of significance in p-values (see Methods, Results, and the ANOVA in Table S1): * = significant; ** = very significant; *** = extremely significant; the plus sign (+) shows an almost statistically significant instance. Note that scales of plots differ.
