Increased resistance to thermal shock in pacific white shrimp fed on green algae and its effect in conjunction with probiotics
<p>This study aimed to evaluate the <em>in vivo </em>effect of the macroalgae <em>Ulva ohnoi, </em>alone and combined with the probiotic <em>Lactobacillus plantarum, </em>on zootechnical, immunological, and microbiological performance, thermal resistance and survival of <em>Litopenaeus vannamei </em>challenged with <em>Vibrio parahaemolyticus. </em>The shrimp were fed four diets: control, seaweed, probiotic, and a combination of seaweed + probiotic. After six weeks, a significant difference between the control and probiotic, and the control and seaweed treatments was demonstrated in shrimp challenged with <em>Vibrio</em>, with the highest percentage of mortality being observed in the group fed only with seaweed, followed by probiotic, seaweed + probiotic, and control. The control and seaweed treatment groups also showed a significant difference in resistance to hermal shock. The animals treated with the control diet had the highest mortality rate, followed by seaweed + probiotic, probiotic, and seaweed. The zootechnical, immunological, and microbiological parameters</p>

Data from: Growth responses of a green alga to multiple environmental drivers
One feature of global change is that biota must respond not to single, but to multiple environmental drivers. By growing a model photosynthetic microbe in environments containing between one and eight different drivers, including changes in CO2, temperature, and pH, in different combinations, we show that the number as well as the identities of drivers explain shifts in population growth rates. This is because the biotic response to multiple environmental drivers depends on the response to the single dominant driver, and the chance of a driver of large effect being present increases with the number of drivers. Interactions between drivers slightly counteract the expected drop in growth. Our results demonstrate that population growth declines in a predictable way with the number of environmental drivers, and provide an empirically supported model for scaling up from studies on organismal responses to single drivers to predict responses to large numbers of environmental drivers.
Data from: Distinctive architecture of the chloroplast genome in the chlorodendrophycean green algae Scherffelia dub and Tetraselmis sp. CCMP 881
The Chlorodendrophyceae is a small class of green algae belonging to the core Chlorophyta, an assemblage that also comprises the Pedinophyceae, Trebouxiophyceae, Ulvophyceae and Chlorophyceae. Here we describe for the first time the chloroplast genomes of chlorodendrophycean algae (Scherffelia dubia, 137,161 bp; Tetraselmis sp. CCMP 881, 100,264 bp). Characterized by a very small single-copy (SSC) region devoid of any gene and an unusually large inverted repeat (IR), the quadripartite structures of the Scherffelia and Tetraselmis genomes are unique among all core chlorophytes examined thus far. The lack of genes in the SSC region is offset by the rich and atypical gene complement of the IR, which includes genes from the SSC and large single-copy regions of prasinophyte and streptophyte chloroplast genomes having retained an ancestral quadripartite structure. Remarkably, seven of the atypical IR-encoded genes have also been observed in the IRs of pedinophycean and trebouxiophycean chloroplast genomes, suggesting that they were already present in the IR of the common ancestor of all core chlorophytes. Considering that the relationships among the main lineages of the core Chlorophyta are still unresolved, we evaluated the impact of including the Chlorodendrophyceae in chloroplast phylogenomic analyses. The trees we inferred using data sets of 79 and 108 genes from 71 chlorophytes indicate that the Chlorodendrophyceae is a deep-diverging lineage of the core Chlorophyta, although the placement of this class relative to the Pedinophyceae remains ambiguous. Interestingly, some of our phylogenomic trees together with our comparative analysis of gene order data support the monophyly of the Trebouxiophyceae, thus offering further evidence that the previously observed affiliation between the Chlorellales and Pedinophyceae is the result of systematic errors in phylogenetic reconstruction.
