Intensity and mode of Lindera melissifolia reproduction are affected by flooding and light availability
<p>A water impoundment facility was used to control the duration of soil flooding (0, 45, or 90 days) and shade houses were used to control light availability (high = 72 %, intermediate = 33 %, or low = 2 % of ambient light) received by L. melissifolia established on native soil of the MAV. A completely randomized, split-plot design was used to evaluate the effects of soil flooding and light availability on L. melissifolia reproductive intensity and mode. Analyses were conducted on plot means using PROC GLIMMIX with an adjustment in the error term for the whole-plot factor (SAS 9.4, SAS Institute, Inc., Cary, North Carolina, USA). PROC UNIVARIATE was used to test data normality for each response variable, and residual errors were normalized with Box-Cox, natural log, or square root transformations where appropriate prior to the PROC GLIMMIX analyses. Significance was accepted at ∝ = 0.05, and we used the least significant difference (LSD) test to separate significant treatment effect means. When a soil flooding and light availability interaction was significant, separation of soil flooding level means was conducted by light availability level, and separation of light availability level means was conducted by soil flooding level.</p>
Data for: Experimental test of the influence of light availability on the evolution of eye size and behavior in Daphnia
<p>There exists extensive variation in eye size. Much work has provided a connection between light availability and differences in eye size across taxa. Experimental tests of the role of the light environment on the evolution of eye size are lacking. Here we performed a selection experiment that examined the influence of light availability on shifts in eye size and the connection between eye size and phototactic (anti-predator) behavior in <em>Daphnia</em>. We set up replicate experimental populations of <em>Daphnia</em>, repeatedly evaluated phenotypic shifts in eye size during the ~50-day experiment and performed a common garden experiment at the end of the experiment to test for evolutionary shifts in eye size and behavior. Our phenotypic analyses showed that eye size rapidly diverged between the light treatments; relative eye size was consistently larger in the low versus high light treatments. Selection on eye size was also modified by variation in density as increases in <em>Daphnia</em> density favored a larger eye. However, we did not observe differences in eye size between the light treatments following two generations of common garden rearing at the end of the experiment. We instead observed strong shifts in anti-predator behavior. <em>Daphnia</em> from the low light treatment exhibited decreased phototactic responses to light. Our results show that decreased light relaxes selection on anti-predator behavior. Such trends provide new insights into selection on eye size and behavior. </p>

Tree light availability:FAB 1 : Forests and Biodiversity Experiment - High density diversity
A forest biodiversity experiment (FAB) focused on trees of our region investigates the consequences of multiple dimensions of tree diversity for soil, food webs, plant communities and ecosystems. FAB is designed to unravel effects of three forms of biological diversity: species richness (SR), functional diversity (FD), and phylogenetic diversity (PD). We define FD as the representation of multiple traits of leaves, roots, seeds, and the whole organism that are correlated with species positions along gradients of resource supply, growth, and decomposition. PD is the representation of evolutionary lineages measured as the genetic distances between species. While PD and FD are often correlated, convergent evolution and adaptive differentiation can decouple them. When functional traits that drive specific ecosystem functions are not phylogenetically conserved, PD and FD may give contrasting predictions. SR, PD, and FD are not independent, and we posit that PD may help explain SR effects, and FD may help explain both PD and SR effects. Thus FAB is designed to examine the separate and combined effects of all three components of diversity for multiple ecosystem functions and to distinguish between ???sampling??? and ???complementarity??? effects of biodiversity. Due to the long lag between planting tree seedlings and determining effects of tree composition and diversity on ecosystem functioning, fewer experiments have been established to elucidate the role of biodiversity in the functioning of forest ecosystems than grassland experiments. FAB will contribute to this gap and is a member of the IDENT and TreeDiv network of forest biodiversity experiments (www.treedivnet.ugent.be). Hypotheses: 1. PD, FD, and SR will all contribute to increased productivity, stability, and diversity of other trophic levels (herbivores, predators, parasitoids, soil microbes, soil flora and fauna) as well as to greater soil C sequestration. 2. Because PD incorporates both the number of species a
Light availability and rhizobium variation interactively mediate the outcomes of legume-rhizobium symbiosis
<p><span><span><span><span><span><span><span><span><span><span><span><b>Premise of the study:</b> Nutrients, light, water, and temperature are key factors limiting the growth of individual plants in nature. Mutualistic interactions between plants and microbes often mediate resource limitation for both partners. In the mutualism between legumes and rhizobia, plants provide rhizobia with carbon in exchange for fixed nitrogen.</span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span>Because partner quality in mutualisms is genotype-dependent, within-species genetic variation is expected to alter the responses of mutualists to changes in the resource environment. Here we ask whether partner quality variation in rhizobia mediates the response of host plants to changing light availability, and conversely, whether light alters the expression of partner quality variation. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Methods:</b> We inoculated clover hosts with 11 rhizobium strains that differed in partner quality, grew plants under either ambient or low light conditions in the greenhouse, and measured plant growth, nodule traits, and foliar nutrient composition. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Key results:</b> Light availability and rhizobium inocula interactively determined plant growth, and rhizobium partner quality variation was more apparent in ambient light. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Conclusions:</b> Our results suggest that variation in the costs and benefits of rhizobium symbionts mediate host responses to light availability, and that rhizobium variation might more important in higher-light environments.

Figure 3 - Example of a new name established in a chaotically arranged early zoological work. Detail of Hartmann (1821: p. 231), with the original description of Helix ruderata Hartmann, 1821 (currently Discus ruderatus). For the non-insider it is very difficult to see that a new name was established here. It is necessary to understand precisely the content of the German text: "s. meine Tab. II. f. 11. Der vorigen ähnlich, aber aufgeblasener, rauher, weniger Umgänge" (= see my plate II, figure 11. Similar to the previous one, but more inflated, rougher, fewer whorls).

Figure 1 - Number of names. Total number of taxonomic names listed in Sherborn's Index Animalium and in AnimalBase (2011) plotted in 5-year intervals. It must be taken into account that Sherborn's numbers included a proportion of 30% of names that were not new, while in AnimalBase this proportion was much lower (less than 5 %).
