Nonadditive Interaction

We assessed the extent to which temperature interacts with maternal contributions to egg size to affect development time and size of yellowtail flounder (Pleuronectes ferrugineus) larvae at hatch. Maternal effects contributed significantly to differences in egg sizes produced by four females. Eggs from each female were incubated at five temperatures. Development time was most significantly affected by temperature, and female effects were minimal. However, the variance in development time within a population was significantly affected by an interaction between female and temperature effects. Average length at hatch varied significantly among temperatures and females, as did the variance in hatching length within a population. Variance in hatching length explained by maternal effects peaked at intermediate temperatures (~38% explained variance at 7°C), while variance explained by covariation with development time increased linearly with temperature, explaining ~40% variance at 13°C. Overall, the nonadditive interaction between maternal contributions and the environment suggests that female effects must be considered over the entire range of environmental conditions experienced by their progeny. In addition, our results support the idea that it is inappropriate to quantify female effects among eggs and extrapolate these differences to larvae.

Phylogenetic Lineages

Genus- and species-level differences characterize the pattern of life-history variation in two distinct phylogenetic lineages of chrysopids, Chrysopa and Chrysoperla. Species in the genus Chrysopa exhibit significant variation in egg size, and this variation is positively correlated with the ability of hatchlings to withstand periods of food and water deprivation prior to their initial feeding. The variation is also significantly correlated with larval size, as measured by the tibial length of first-instar larvae. Although the six Chrysopa species differ in several other life-history traits (i.e, the incubation period and rate of first-instar larval development), the variation is unrelated to egg size. It appears that maternal allocation of resources to eggs largely serves to enhance embryonic growth and the survival of hatchlings during searching. That is, within the Chrysopa lineage egg size varies; larger eggs yield larger, more robust hatchlings. These hatchlings may or may not develop faster than congeners from small eggs. In comparison with Chrysopa, the genus Chrysoperla has less variability in egg size and developmental rate. Furthermore, although Chrysoperla eggs are relatively small, the ability of hatchlings to endure periods of food or water deprivation is at least as great as it is in the Chrysopa species with large eggs. We conclude that maternal investment in larval fitness has different ontogenetic pathways, ecological roles, and phylogenetic histories in the two genera.

Transgenerational effects are important for phenotypic plasticity and adaptation of marine invertebrates in the changing ocean. Ultraviolet-B (UV-B) radiation is an increasing threat to marine invertebrates. For the first time, we reported positive and negative transgenerational effects of UV-B radiation on egg size, fertilization, hatchability and larval size of a marine invertebrate. Strongylocentrotus intermedius exposed to UV-B radiation showed positive transgenerational effects and adaptation on egg size, hatching rate and post-oral arm length of larvae. Negative transgenerational effects were found in body length, stomach length and stomach width of larvae whose parents were exposed to UV-B radiation. Sires probably play important roles in transgenerational effects of UV-B. The present study provides valuable information into transgenerational effects of UV-B radiation on fitness related traits of sea urchins (at least Strongylocentrotus intermedius).

Indirect Genetic Effects

With global temperatures projected to surpass the limits of thermal tolerance for many species, evaluating the heritable variation underlying thermal tolerance is critical for understanding the potential for adaptation to climate change. We examined the evolutionary potential of thermal tolerance within a population of chinook salmon ( Oncorhynchus tshawytscha ) by conducting a full-factorial breeding design and measuring the thermal performance of cardiac function and the critical thermal maximum (CT max ) of offspring from each family. Additive genetic variation in offspring phenotype was mostly negligible, although these direct genetic effects explained 53% of the variation in resting heart rate ( f H ). Conversely, maternal effects had a significant influence on resting f H , scope for f H , cardiac arrhythmia temperature and CT max . These maternal effects were associated with egg size, as indicated by strong relationships between the mean egg diameter of mothers and offspring thermal tolerance. Because egg size can be highly heritable in chinook salmon, our finding indicates that the maternal effects of egg size constitute an indirect genetic effect contributing to thermal tolerance. Such indirect genetic effects could accelerate evolutionary responses to the selection imposed by rising temperatures and could contribute to the population-specific thermal tolerance that has recently been uncovered among Pacific salmon populations.

AbstractChameleons lay flexible-shelled eggs that are affected by environmental characteristics during incubation. We incubated eggs of six clutches under four treatments using two different constant temperatures (25 and 29°C) and water potentials (-150 kPa and-600 kPa). Eggs gained mass in all treatments, especially under the wetter and warmer conditions. Temperature, not water potential, affected hatching rate, which was 100% under 25°C and 64% under 29°C. Development time was considered as the period during which eggs were incubated under both constant temperatures and differed between treatments, from an average length of 98.8 days in the wettest and warmest media to 144.2 days in the driest and coldest one. Differences in hatchling phenotype were mostly explained by clutch identity, although it was also affected by incubation treatments, with bigger and heavier hatchlings in colder treatments. Incubation conditions did not affect hatchling growth nor survival rates, but survivors were differentiated by their higher increase in egg mass during incubation. Los huevos de los camaleones tienen la cáscara flexible, estando influidos por las características del medio en que se encuentran. Se incubaron huevos de seis puestas en cuatro tratamientos, usando dos temperaturas de incubación constantes (25 y 29°C) y dos potenciales hídricos (-150 kPa y-600 kPa). Los huevos incrementaron de peso en todos los tratamientos, principalmente en los de condiciones más húmedas y cálidas. La tasa de eclosión resultó influida por el efecto de la temperatura, pero no por el del potencial hídrico. Eclosionó el 100% de los huevos incubados a 25°C y el 64% de los incubados a 29°C. Se apreciaron diferencias en la duración del desarrollo entre los huevos incubados en los distintos tratamientos, variando el promedio entre 98.8 días (en las condiciones más húmedas y cálidas) y 144.2 días (en el más seco y frío). Las diferencias apreciadas en el fenotipo de las crías se atribuyen principalmente a su origen materno, aunque también se apreciaron influencias de las condiciones de incubación, resultando crías de mayor tamaño y peso en los tratamientos de menor temperatura. Las condiciones de incubación no afectaron al crecimiento ni a la supervivencia de las crías, sobreviviendo las que procedían de huevos con mayor incremento de peso durante la incubación.

Hormonally mediated maternal effects link maternal phenotype and environmental conditions to offspring phenotype. The production of lipid-rich maternal yolk precursors may provide a mechanism by which lipophilic steroid hormones can be transported to developing yolks, thus predicting a positive correlation between yolk precursors in mothers and androgen levels in eggs. Using rockhopper penguins ( Eudyptes chrysocome ), which produce a two-egg clutch characterized by extreme egg-size dimorphism, reversed hatching asynchrony and brood-reduction, we examined correlations between circulating concentrations of the primary yolk-precursor vitellogenin (VTG) and levels of yolk androgens. Previous work in Eudyptes penguins has shown that egg-size dimorphism is the product of migratory constraints on yolk precursor production. We predicted that if yolk precursors are constrained, androgen transport to developing yolks would be similarly constrained. We reveal positive linear relationships between maternal VTG and androgens in small A-eggs but not larger B-eggs, which is consistent with a migratory constraint operating on the A-egg. Results suggest that intra-clutch variation in total yolk androgen levels depends on the production and uptake of yolk precursors. The brood reduction strategy common to Eudyptes might thus be best described as the result of a migratory constraint.
