Fig. 1 in Growth and reproduction in captivity unveils remarkable life-history plasticity in the smallnose fanskate, Sympterygia bonapartii (Chondrichthyes: Rajiformes)
Fig. 1. Growth of Sympterygia bonapartii born at Temaikèn Aquarium (Argentina). Individual growth trajectories (n = 21 males and 13 females) are shown as grey lines. The Logistic model (bold black line) is the one with the best fit to the data (lowest Akaike Information Criterion). Other models fitted are von Bertalanffy with size at birth (VB1), von Bertalanffy with t0 parameter (VB2), and Gompertz models. The best model describing the growth of wild S. bonapartii (bold dashed line) from off northern Argentina, as estimated by Hozbor and Massa (2015), has the same form as VB1.
Decoupling the effects of food and density on life history plasticity of wild animals using field experiments: Insights from the steward who sits in the shadow of its tail, the North American red squirrel
<p>Long-term studies of wild animals provide the opportunity to investigate how phenotypic plasticity is used to cope with environmental fluctuations, and how the relationships between phenotypes and fitness can be dependent upon the ecological context.</p> <p>Most previous studies have only investigated life history plasticity in response to changes in temperature, yet wild animals often experience multiple environmental fluctuations simultaneously. This requires field experiments to decouple which ecological factor induces plasticity in fitness-relevant traits to better understand their population-level responses to those environmental fluctuations.</p> <p>For the past 32 years, we have conducted a long-term integrative study of individually marked North American red squirrels (<i>Tamiasciurus hudsonicus </i>Erxleben) in the Yukon, Canada. We have used multi-year field experiments to examine the physiological and life history responses of individual red squirrels to fluctuations in food abundance and conspecific density.</p> <p>Our long-term observational study and field experiments show that squirrels can anticipate increases in food availability and density, thereby decoupling the usual pattern where animals respond to, rather than anticipate, an ecological change.</p> <p>As in many other study systems, ecological factors that can induce plasticity (such as food and density) co-vary. However, our field experiments that manipulate food availability and social cues of density (frequency of territorial vocalizations) indicate that increases in social (acoustic) cues of density in the absence of additional food can induce similar life history plasticity, as does experimental food supplementation.</p> <p>Changes in the levels of metabolic hormones (glucocorticoids) in response to variation in food and density are one mechanism that seems to induce this adaptive life history plasticity. </p> <p>Although we have not yet investigated the energetic response of squirrels to elevated density or its association with life history plasticity, energetics research in red squirrels has overturned several standard pillars of knowledge in physiological ecology.</p> <p>We show how a tractable model species combined with integrative studies can reveal how animals cope with resource fluctuations through life history plasticity.</p>
A three year trans-generational plasticity in life history traits
<p>1. Environmental conditions of maternal plants influence adaptive strategies of their progeny via the seed phenotype. Although traditionally, studies have explained patterns of reproduction traits in response to stresses, such as the changes in seed mass and seed germinability under different maternal conditions. However, it is still unclear how maternal effects affect progeny dispersal and germination strategy or how many generations plasticity persists.</p> <p><span>2. Plants from diaspore types A and C of the diaspore-heteromorphic annual halophyte <i>Atriplex centralasiatica</i> were grown in low (favorable) vs. high (stressful) salinities over three generations in a fully factorial design. We measured life history traits and reproductive characteristics of progeny plants for a three-year transgenerational plasticity (TGP) experiment covering F0, F1, and F</span></p> <p><span>3. TGP of plants grown in favorable vs. stressful salinities decreased from F2 → F1 → F0. Compared to the favorable condition, the stressful condition decreased the length of the vegetative period, extended length of reproductive time and increased reproductive allocation and size of progeny diaspores. Salinity tolerance and phenotypic plasticity were higher in plants from diaspore A than in those from diaspore C. In the stressful condition, plants produced less plant biomass, larger diaspores, a higher proportion of type C diaspores with dormancy and higher dispersal potential, but lower proportion of type A diaspores with nondormancy and lower dispersal potential. In addition, production of the proportion of type C diaspores increased with increase in number of previous generations that experienced stress. </span></p> <p>4. Synthesis: The trade-off of reproductive allocation between diaspores A versus C enables plants to develop divergent strategies via both high diaspore C allocation to disperse progeny spatiotemporally across wide areas in stress conditions and high diaspore A allocation to limit progeny near maternal plants in favorable habitats. These findings provide evidence for the "escape strategy" by which the progeny of <i>A. centralasiatica</i> diffused spatially (dispersal) and temporally (dormancy) by TGP, thus allowing them to survive environmental heterogeneity in their cold desert habitats.</p>
Data from: Plastic responses of some life history traits and cellular components of body size in Aphidius ervi as related to the age of its host Acyrthosiphon pisum
Phenotypic plasticity of wing size and shape has been evaluated in Aphidius ervi developing in its host, Acyrthosiphon pisum, parasitized at seven different ages. The parasitoid wing size was used as an estimator of both whole body size and its cellular composition. No size difference was observed in A. ervi adults emerged from aphids 1, 2 or 3 days old at parasitization. Body size then increased in A. ervi emerged from hosts older at parasitization. Body size values as related to host age at parasitization were achieved by adjusting developmental time, developmental rate or both. Parasitoids of similar size, but developed in hosts parasitized at different ages, had different wing cellular composition, while the increase of parasitoid body size was related to a general increase in both cell area and cell number. These results seem to suggest a trade-off between adult size and developmental time, at least for parasitoids developed at the two extremes of host ages at parasitization, and that A. ervi can reach the same adult size via different trajectories, adapting its ontogenetic processes. Wing shape was typical for all the different parasitoid classes considered and differed strongly between males and females, independent of their size. Parasitoid males (haploids) and females (diploids) did not differ in either cell area or cell number, suggesting a possible sex-determined dosage compensation in somatic tissue endoreplication.
Data from: Extreme climate-induced life-history plasticity in an amphibian
Age specific survival and reproduction are closely linked to fitness and therefore subject to strong selection that typically limits their variability within species. Furthermore, adult survival rate in vertebrate populations is typically less variable over time than other life history traits, such as fecundity or recruitment. Hence, adult survival is often conserved within a population over time, compared to the variation in survival found across taxa. In stark contrast to this general pattern, we report evidence of extreme short-term variation of adult survival in Rose's Mountain Toadlet (Capensibufo rosei), which is apparently climate-induced. Over seven years, annual survival rate varied between 0.04 and 0.92, and 94% of this variation was explained by variation in breeding-season rainfall. Preliminary results suggest that this variation reflects adaptive life-history plasticity to a degree thus far unrecorded for any vertebrate, rather than direct rainfall induced mortality. In wet years, these toads appeared to achieve increased reproduction at the expense of their own survival whereas in dry years, their survival increased at the expense of reproduction. Such environmentally induced plasticity may reflect a diversity of life-history strategies not previously appreciated among vertebrates.
Data from: The plastic fly: the effect of sustained fluctuations in adult food supply on life history traits
Many adult traits in Drosophila melanogaster show phenotypic plasticity, and the effects of diet on traits such as lifespan and reproduction are well explored. Although plasticity in response to food is still present in older flies, it is unknown how sustained environmental variation affects life-history traits. Here, we explore how such life-long fluctuations of food supply affect weight and survival in groups of flies and affect weight, survival and reproduction in individual flies. In both experiments, we kept adults on constant high or low food and compared these to flies that experienced fluctuations of food either once or twice a week. For these 'yoyo' groups, the initial food level and the duration of the dietary variation differed during adulthood, creating four 'yoyo' fly groups. In groups of flies, survival and weight were affected by adult food. However, for individuals, survival and reproduction, but not weight, were affected by adult food, indicating that single and group housing of female flies affects life-history trajectories. Remarkably, both the manner and extent to which life-history traits varied in relation to food depended on whether flies initially experienced high or low food after eclosion. We therefore conclude that the expression of life-history traits in adult life is affected not only by adult plasticity, but also by early adult life experiences. This is an important but often overlooked factor in studies of life-history evolution and may explain variation in life-history experiments.
