Introduction Maternal effects are defined as modifications of offspring phenotype caused by the maternal phenotype or the environment that mothers experience [1]. Maternal effects are a prime mechanism in the control of phenotypic variation [1] and have been demonstrated across a wide variety of living organisms in both plants e. Of the many potential mediators of maternal effects, maternally-derived hormones [7] — [10] are especially interesting since hormones are well-known to play a major role in organizing phenotypic differentiation and regulating physiological functions [11]. Among maternally-derived hormones, testosterone T has received particular attention [12] — [14] since it can have profound effects on embryo development [7] , [15] — [18] with short- and long-term consequences for both offspring and adult behaviour [19] — [25]. High concentrations of maternally-derived T may increase post-natal growth [17] , [26] — [29] and offspring competitiveness in sibling interactions [16] , [28] , [30] — [33].

Its anabolic properties [34] may lead, for instance, to accelerated growth of the neck muscles involved in begging or sucking [35] — [37]. Besides these beneficial effects, high levels of maternal T have also been shown to have costs [7] , [38] — [40]. Yolk T may directly suppress immune functions [41—44, but see 45], contribute to metabolic dysfunctions e.

Whether deposition of high levels of T in the yolk comes at a cost for the females is still debated. Some studies found that transferring high amounts of T to the embryo or into the eggs may inflict costs to the mother reviewed by [21] , [22] , while others provide evidence that the deposition of high levels of T in the yolk does not require elevated levels of circulating androgens, thus suggesting no cost to the female [9] , [50].

Multiple Choice Questions (MCQ) On Clutch
Posted on 23-May-2021
Nevertheless, owing to the potentially opposing costs and benefits of maternally-derived T for offspring, and to some extent for females, mothers are expected to optimize the allocation of testosterone to the embryo or egg reviewed in [9] , [21]. Strategic allocation of T would then underlie variation in the levels of T found in the egg yolk or in the blood of neonates across clutches or litters produced by different mothers [16] , [51]. Furthermore, it may also underlie variation in the levels of T found in the egg yolk or in the blood of neonates within the clutch or the litter of a given mother [7] , [52] , [53]. This latter pattern of variation in the levels of maternally-derived T across eggs or neonates is mostly seen in oviparous and ovoviviparous species where mechanisms allowing the mother to adjust the amount of T deposited into each of the eggs are more likely to have evolved [7] , [14] , [21] , [28].

Questions And Answers Of CLUTCH
Posted on 3-May-2021
Asynchronous hatching establishes an age hierarchy within a brood, which may then result in a competitive advantage for older, first-hatched chicks over their younger siblings [60]. The combination of hatching asynchrony and varying levels of yolk T can influence offspring growth and begging ability, and may thus allow mothers to adaptively tune the survival prospects of the offspring to the conditions prevailing during egg laying and anticipated conditions during brood rearing [61]. It has been hypothesized that by depositing higher levels of T with increasing laying order, females could mitigate the negative consequences of sibling asymmetry by increasing the competitive ability of the chicks hatched from the last-laid eggs when food is plentiful, or handicap those chicks when food is scarce [7] , [14] , [28] , [58] , [62]. Higher T-levels induce metabolic costs e.

These costs may be more than compensated by the benefits of T-induced higher competitiveness under good food conditions, but become a handicap under bad conditions [7] , [58]. The opposite pattern, i. In this latter case, the higher levels of maternally-derived T in the first-laid eggs would boost the competitive ability of the first-hatched chicks and precipitate brood reduction via the death of the less competitive chick s hatched from the last-laid egg s [9] , [56]. The fact that strong natural variation in T concentration occurs within clutches is of importance since it potentially affects the dynamics of family interaction and sibling competition by creating variation in competitive ability. It may thus lead to a different outcome than the more frequently studied variation in T concentrations among clutches where all siblings are potentially rendered more or less competitive.

To our knowledge, only a few studies manipulated the levels of yolk T within clutches directly, and investigated the adaptive significance of varying concentrations of yolk T in relation to the laying order in a context of hatching asynchrony. Examples include Black-headed gulls [31] , [62] , Canaries [64] , American kestrels [65] , and Zebra finches [66]. Although it is generally assumed that within-clutch variation in maternal T serves to mitigate the negative effects of hatching asynchrony on last-hatched offspring, contradictory findings mainly due to differences in methods used, call for additional work to better understand the functional significance of within-clutch variation in T concentration. Most of the previous studies tested the effects of T by experimental creation of clutches were T in first-laid eggs was increased to the levels of the last-laid eggs.

However the manipulated clutches contained eggs originating from different mothers, with the potential problems of an inflation of within-brood variance in offspring traits through genetic effects and gene-by-environment effects, a modification of the clutch sex-ratio and a disruption of within-clutch T-allocation patterns. To our knowledge, only one study compared the effects of high yolk T in a context of hatching asynchrony by manipulating levels of T in both first and last-laid eggs at the same time [64]. We conducted a field experiment where we manipulated within-clutch T concentration in great tit Parus major eggs in order to assess whether higher levels of yolk T enhance the growth and survival of the first- or last-hatched chicks and thus would be compatible with a brood reduction or a compensatory strategy respectively.

We created three types of clutches: 1 clutches where the first three eggs were injected with T and the remaining eggs with sesame oil, 2 clutches where the last three eggs were injected with T and the remaining eggs with sesame oil, and 3 control clutches where all eggs were injected with sesame oil. We thus manipulated yolk hormone concentrations of eggs to mimic the natural variation in yolk T with laying order within clutches.

The experimental design and predictions are based on the findings e. In this study hatching success was reduced following injection see below , and thus inadvertently created an experimental situation where food conditions were improved and sibling competition weakened. Reduced brood size is well known to have strong positive effects on chick quality, fledging success and parental condition in great tits [68]. Consequently, we decided to narrow our predictions down to the situation of good food conditions. Therefore, we predicted that in broods where T is injected into the first-laid eggs, first-hatched chicks should achieve higher fitness grow larger and heavier and have higher fledging success than last-hatched chicks within the same brood. Compared to first-hatched chicks in control broods, T-injected first-hatched chicks may perform equally well or better depending on how strongly additional yolk T will alter their ability to monopolize food and parental care.

Eggs were injected after clutch completion to limit the disturbance to females during egg laying and to keep our workload within feasible daily limits. To ensure correct statistical analyses and mimic higher levels of T in either the first- or last-laid eggs, we have chosen to inject more than one egg. The amount of T injected in this study fits into the range of concentrations of yolk T previously found in the same species e. Also, a precursor of testosterone, androstenedione A4, is found in considerably higher quantities than T in all three studies mentioned e. Since A4 can be converted to T by the embryo even at early stages [9] , [71] , the injected dose of T may thus be in a physiological range that is relevant for addressing its functions in brood reduction. A previous study injected this exact amount into egg yolks and found positive effects on chick growth [45].

All injections were performed in the field. During manipulation, the eggs were replaced with dummy eggs in the nest for approximately a half hour. Within a clutch, the eggs of the different treatments T or sesame oil received different colours. The colorant sticks to the hatchling and is visible after hatching and thus allows individual identification. The colour used with respect to treatment and position in the laying sequence was assigned randomly red or green. A total of eggs were injected, out of which chicks hatched. The overall hatching success, as measured by the number of hatched chicks over clutch size, was Nest Monitoring Around the predicted date of hatching, we visited the nests every day to determine the hatching date of the first chicks in the brood day 0.

In our study population hatching spread was 0. On day 3, when all chicks had hatched, we individually marked chicks by removing specific combinations of tuft feathers, and could assign them unequivocally to the previous treatment since the colorants were still clearly visible. Chicks were ringed 8 days after hatching with an aluminium ring Vogelwarte, Sempach, Switzerland. Thirteen days after hatching chicks were weighed to the nearest 0. Nests were checked daily from day 16 onwards to record the number of young fledged and the fledging date.

They were then shaken for 30 min and again frozen overnight. The next day, samples were thawed, centrifuged for 15 min at G, and 1 ml of the supernatant transferred into a new vial. Sensitivity of the assay was 0. Minimum detectable hormone level was 1. To test whether the amount of yolk T varied according to the laying order we used linear mixed models with normal distribution of errors. To overcome the potential bias that would be generated by a positive covariation between clutch size and overall T levels in the eggs i. Laying order of eggs ranging from 4 to 11 was included in the model as a covariate and brood identity as a random factor. Additionally, we tested whether the average amount of T was related to clutch size using a general linear model with normal distribution of the error.

To test the randomisation of our treatments for clutch size, we used a generalized linear model with Poisson errors where treatment was included as a fixed factor. A general linear model with normal distribution of errors was used to investigate whether brood size on day 3 differed according to the treatments. To test whether laying order of eggs predicts hatching order of the chicks we used generalized mixed models with binomial errors. Hatching spread was limited in our study with only 2.

We therefore pooled the later hatched chicks to create a binary response variable: hatched first vs. Fixed factors and covariates were as follows: position of the egg in the laying sequence two levels factor: first or last , clutch size and laying date of the first egg in the clutch. The brood identity was entered as a random factor. To investigate the effects of elevated levels of yolk T in first- and last-laid eggs on chick morphology we conducted two types of comparisons. First, we did within-brood comparisons where we tested the effects of T on chicks in relation to the laying position of the eggs from which those chicks hatched. Second, we conducted all pair-wise comparisons between broods to test our predictions see Introduction and to investigate the performance of each type of chick relative to all other chicks from control and T-injected broods.
