Data from: Genome assembly of the ragweed leaf beetle, a step forward to better predict rapid evolution of a weed biocontrol agent to environmental novelties

Rapid evolution of weed biological control agents (BCAs) to new biotic and abiotic conditions is poorly understood and so far, only little considered both in pre-release and post-release studies, despite potential major negative or positive implications for risks of non-targeted attacks or for colonizing yet unsuitable habitats, respectively. Provision of genetic resources, such as assembled and annotated genomes, is essential to assess potential adaptive processes by identifying underlying genetic mechanisms. Here, we provide the first sequenced genome of a phytophagous insect used as a BCA, i.e. the leaf beetle Ophraella communa, a promising BCA of common ragweed, recently and accidentally introduced into Europe. A total 33.98 Gb of raw DNA sequences, representing c. 43-fold coverage, were obtained using the PacBio SMRT-Cell sequencing approach. Among the five different assemblers tested, the SMARTdenovo assembly displaying the best scores was then corrected with Illumina short reads. A final genome of 774 Mb containing 7,003 scaffolds was obtained. The reliability of the final assembly was then assessed by benchmarking universal single-copy orthologous genes (> 96.0% of the 1,658 expected insect genes) and by remapping tests of Illumina short reads (average of 98.6% ± 0.7% without filtering). The number of protein-coding genes of 75,642, representing 82% of the published antennal transcriptome, and the phylogenetic analyses based on 825 orthologous genes placing O. communa in the monophyletic group of Chrysomelidae, confirm the relevance of our genome assembly. Overall, the genome provides a valuable resource for studying potential risks and benefits of this BCA facing environmental novelties.

Data from: Foraging sparrows exhibit individual differences but not a syndrome when responding to multiple types of novelty

Differences between individuals in correlated responses across contexts have both functional and mechanistic implications. Such syndromes may have either beneficial or harmful consequences when novel changes in the environment occur. We used wild-caught house sparrows, Passer domesticus, to test in functionally relevant circumstances, whether neophobia (initial fear of novelty), habituation, and the learning of novel cues (discriminant learning) were linked by a common underlying mechanism or reflected separate processes. We repeatedly measured individual latencies to approach and also to feed from a familiar feeding site in three contexts: a baseline control for mild disturbance, in the presence of a novel object, and to a novel cue indicating hidden food. House sparrows on average exhibited neophobia, habituated to novel objects, and learned to associate new cues to a reward. We also found evidence for consistent individual differences in in both latencies within most contexts, but there was no evidence of individual differences in plasticity with repeated trials within either the novel object (habituation) or novel cue (learning) contexts. There was also little or no correlation between the two latencies within individuals within contexts. Individual differences in latencies to arrive at the food station exhibited strong correlations across contexts, but latencies to feed were weaker. These results suggest a personality trait that exists regardless of novelty, but no syndrome affecting reactions to different forms of novelty. House sparrows appear strongly plastic when responding to novel environments. Such plasticity is likely favored by the varied consequences of novelty across environments.

Data from: Emergence patterns of novelty in European vegetation assemblages over the past 15,000 years

Plant communities are not stable over time and biological novelty is predicted to emerge due to climate change, the introduction of exotic species and land-use change. However, the rate at which this novelty may arise over longer time periods has so far received little attention. We reconstruct the emergence of novelty in Europe for a set of baseline conditions over the past 15 000 years to assess past rates of emergence and investigate underlying causes. The emergence of novelty is baseline specific and, during the early-Holocene, was mitigated by the rapid spread of plant taxa. Although novelty generally increases as a function of time, climate and human-induced landscape changes contributed to a non-linear post-glacial trajectory of novelty with jumps corresponding to periods of rapid changes. Emergence of novelty accelerated during the past 1000 years. Historical cultural landscapes experienced a faster novelty development due to the contribution from anthropogenic land-cover changes.

Electronic supplementary information: Independent and adaptive evolution of phenotypic novelties is driven by coral symbiosis in barnacle larvae

The invasion of novel habitats is recognized as a major promotor of adaptive trait evolution in animals. We tested whether similar ecological niches entail independent and adaptive evolution of key phenotypic structures related to larval host invasion in distantly related taxa. We use disparately related clades of coral barnacles as our model system (Acrothoracica: Berndtia and Thoracica: Pyrgomatidae). We analyze the larval antennular phenotypes and functional morphologies facilitating host invasion. Extensive video recordings show that coral host invasion is carried out exclusively by cypris larvae with spear-shaped antennules. These first exercise a series of complex probing behaviors followed by repeated antennular penetration of the soft host tissues, which subsequently facilitates permanent invasion. Phylogenetic mapping of larval form and function related to niche invasion in 99 species of barnacles (Thecostraca) compellingly shows that the spear-phenotype is uniquely associated with corals and penetrative behaviors. These features evolved independently in the two coral barnacle clades and from ancestors with fundamentally different antennular phenotypes. The larval host invasion system in coral barnacles likely evolved adaptively across millions of years for overcoming challenges associated with invading and entering demanding coral hosts. Key words: adaptive host invasion, larval phenotypes, coral barnacle, barnacle phylogeny

Description of two new species and phylogenetic placement of recent taxonomic novelties in the Chilean endemic genus Miersia (Gilliesieae, Allioideae, Amaryllidaceae)

Abstract: Two new species in the Chilean endemic genus Miersia (Gilliesieae, Allioideae, Amaryllidaceae) are introduced: M. stellata and M. raucoana. A morphological description, distribution map, illustration, and the assessment of their conservation status are provided for each new taxon, along with an updated key to all species in Miersia. Additionally, analyses of DNA sequences were performed to inquire the evolutionary affinities of both new species and the recently described, M. putaendensis, within Gilliesieae phylogenetic framework. Data from multiple single-copy nuclear genes, as well as the inclusion of Trichlora and Schickendantziella, are necessary to corroborate the tribe’s phylogeny and reassess its generic classification. Dataset description: Two phylip alignment files were uploaded: 1) Miersia_nov_ITS_3.0.phy, includes sequences of nrDNA ITS (nrITS) region, and 2) Miersia_nov_cpDNA_3.0.phy, includes concatenated sequences of two chloroplast (cpDNA) markers, trnL-F and rbcL. Sequences were aligned using MAFFT v.1.4.0. Three *.bestTree.tre files for 1) nrITS, 2) cpDNA, and 3) concatenated dataset of all loci (nrITS, trnL-F, rbcL). All were inferred using RAxML-NG v.1.1.0 (Kozlov et al. 2019), GTR+Γ as the model of molecular evolution (--model GTR+G), and partitioned by locus. nrITS and cpDNA analyses were performed conducting 50 tree searches using 25 random and 25 parsimony-based starting trees to pick the best-scoring topology (--tree pars{25},rand{25}), and the concatenated analysis included 100 tree searches using 50 random and 50 parsimony-based starting trees (--tree pars{50},rand{50}).  Also, the respective boostrap trees (*.bootstraps.tre) were uploaded for each analysis. Likelihood bootstrap analyses were conducted in RAxML-NG v.1.1.0 with 1,000 pseudoreplicates (--bs-trees 1000). We also uploaded two Nexus files which correspond to sequence data from Escobar et al. (2020, Bot. J. Linn. Soc. 194: 84–99), considering that these are currently not available in TreeBase.

Pelagiella exigua, an early Cambrian stem gastropod with chaetae: lophotrochozoan heritage and conchiferan novelty

Exceptionally well-preserved impressions of two bundles of bristles protrude from the apertures of small, spiral shells of Pelagiella exigua, recovered from the Kinzers Formation (Cambrian, Stage 4, "Olenellus Zone", ~ 512 Ma) of Pennsylvania. These impressions are inferred to represent clusters of chitinous chaetae, comparable to those borne by annelid parapodia and some larval brachiopods. They provide an affirmative test in the early metazoan fossil record of the inference, from phylogenetic analyses of living taxa, that chitinous chaetae are a shared early attribute of the Lophotrochozoa. Shells of Pelagiella exhibit logarithmic spiral growth, microstructural fabrics, distinctive external sculptures, and muscle scars characteristic of molluscs. Hence, Pelagiella has been regarded as a stem mollusc, a helcionelloid expressing partial torsion, an untorted paragastropod, or a fully torted basal member of the gastropod crown group. The inference that its chaeta-bearing appendages were anterior-lateral, based on their probable functions, prompts a new reconstruction of the anatomy of Pelagiella, with a mainly anterior mantle cavity. Under this hypothesis, two lateral-dorsal grooves, uniquely preserved in Pelagiella atlantoides, are interpreted as sites of attachment for a long left ctenidium and a short one, anteriorly on the right. The orientation of Pelagiella and the asymmetry of its gills, comparable to features of several living vetigastropods, nominate it as the earliest fossil mollusc known to exhibit evidence of the developmental torsion characteristic of gastropods. This key adaptation facilitated an evolutionary radiation, slow at first and rapid during the Ordovician that gave rise to the remarkable diversification of the Gastropoda.
