This years challenge, based on the 2017 challenge, is held in cooperation with "Thüringer Fernwasserversorgung" which provides their real-world data set. The task of this years competition is to develop an anomaly detection algorithm for the water- and environmental data set. Early identification of anomalies in water quality data is a challenging task. It is important to identify true undesirable variations in the water quality. At the same time, false alarm rates have to be very low.<br> Additionally to the competition, for the first time in GECCO history we are now able to provide the opportunity for all participants to submit 2-page algorithm descriptions for the GECCO Companion.

Oxygen-mediated plasticity confers hypoxia tolerance in a corallivorous polychaete
<p><span>There is mounting evidence that the deoxygenation of coastal marine ecosystems has been underestimated, particularly in the tropics. These physical conditions appear to have far-reaching consequences for marine communities, and have been associated with mass mortalities. Yet little is known about hypoxia in tropical habitats or about the effects it has on reef-associated benthic organisms. We explored patterns of dissolved oxygen (DO) throughout Almirante Bay, Panama and found a hypoxic gradient, with areas closest to the mainland having the largest diel variation in DO, as well as more frequent persistent hypoxia. We then designed a laboratory experiment replicating the most extreme <i>in situ</i> DO regime found on shallow patch reefs (3 m) to assess the response of the corallivorous fireworm, <i>Hermodice carnaculata</i> to hypoxia. Worms were exposed to hypoxic conditions (8 h ~ 1 mg l<sup>-1 </sup>or 3.2 kPa) 16 times over an 8-week period, and at 4 and 8 weeks their oxygen consumption (respiration rates) were measured upon reoxygenation, along with regrowth of severed gills. Exposure to low DO resulted in worms regenerating significantly larger gills compared to worms under normoxia. This response to low DO was coupled with an ability to maintain elevated oxygen consumption/respiration rates after low DO exposure. In contrast, worms from the normoxic treatment had significantly depressed respiration rates after being exposed to low DO (week 8). This indicates that oxygen-mediated plasticity in both gill morphology and physiology may confer tolerance to increasingly frequent and severe hypoxia in one important coral predator associated with reef decline. </span></p>
Data from: Evolutionary renovation of L/M opsin polymorphism confers a fruit discrimination advantage to ateline New World monkeys
New World monkeys exhibit prominent color vision variation due to allelic polymorphism of the long-to-middle wavelength (L/M) opsin gene. The known spectral variation of L/M opsins in primates is broadly determined by amino acid composition at three sites: 180, 277 and 285 (the "three-sites" rule). However, two L/M opsin alleles found in the black-handed spider monkeys (Ateles geoffroyi) are known exceptions, presumably due to novel mutations. The spectral separation of the two L/M photopigments is 1.5 times greater than expected based on the "three-sites" rule. Yet the consequence of this for the visual ecology of the species is unknown, as is the evolutionary mechanism by which spectral shift was achieved. In the present study, we first examine L/M opsins of two other Atelinae species, the long-haired spider monkeys (A. belzebuth) and the common woolly monkeys (Lagothrix lagotricha). By a series of site-directed mutagenesis, we show that a mutation Y213D (tyrosine to aspartic acid at site 213) in the ancestral opsin of the two alleles enabled N294K, which occurred in one allele of the ateline ancestor, and increased the spectral separation between the two alleles. Second, by modeling the chromaticity of dietary fruits and background leaves in a natural habitat of spider monkeys, we demonstrate that chromatic discrimination of fruit from leaves is significantly enhanced by these mutations. This evolutionary renovation of L/M opsin polymorphism in atelines illustrates a previously unappreciated dynamism of opsin genes in shaping primate color vision.
Data from: Genetic diversity confers colony-level benefits due to individual immunity
Several costs and benefits arise as a consequence of eusociality and group-living. With increasing group size, spread of disease among nest-mates poses selective pressure on both individual immunity and group-level mechanisms of disease resistance (social immunity). Another factor known to influence colony-level expression of disease is intracolony genetic diversity, which in honeybees (Apis mellifera) is a direct function of the number of mates of the queen. Colonies headed by queens with higher mating numbers have less variable infections of decreased intensity, though the underlying mechanisms remain unclear. By pathogen-challenging larvae in vitro, we decoupled larval immune response from mechanisms of social immunity. Our results show that baseline immunity and degree of immune response do not vary with genetic diversity. However, intracolony variance in antimicrobial peptide production after pathogen challenge decreases with increasing genetic diversity. This reduction in variability of the larval immune response could drive the mitigation of disease observed in genetically diverse colonies.
Data from: Bacterial motility confers fitness advantage in the presence of phages
Dispersal provides the opportunity to escape harm and colonize new patches, enabling populations to expand and persist. However, the benefits of dispersal associated with escaping harm will be dependent on the structure of the environment and the likelihood of escape. Here, we empirically investigate how the spatial distribution of a parasite influences the evolution of host dispersal. Bacteriophages are a strong and common threat for bacteria in natural environments and offer a good system with which to explore parasite-mediated selection on host dispersal. We used two transposon mutants of the opportunistic bacteria, Pseudomonas aeruginosa, which varied in their motility (a disperser and a nondisperser), and the lytic bacteriophage ФKZ. The phage was distributed either in the central point of colony inoculation only, thus offering an escape route for the dispersing bacteria; or, present throughout the agar, where benefits of dispersal might be lost. Surprisingly, we found dispersal to be equally advantageous under both phage conditions relative to when phages were absent. A general explanation is that dispersal decreased the spatial structuring of host population, reducing opportunities for parasite transmission, but other more idiosyncratic mechanisms may also have contributed. This study highlights the crucial role the parasites can play on the evolution of dispersal and, more specifically, that bacteriophages, which are ubiquitous, are likely to select for bacterial motility.
Data from: Evidence for specificity in symbiont-conferred protection against parasitoids
Many insects harbour facultative symbiotic bacteria, some of which have been shown to provide resistance against natural enemies. One of the best-known protective symbionts is Hamiltonella defensa, which in pea aphid (Acyrthosiphon pisum) confers resistance against attack by parasitoid wasps in the genus Aphidius (Braconidae). We asked (i) whether this symbiont also confers protection against a phylogenetically distant group of parasitoids (Aphelinidae) and (ii) whether there are consistent differences in the effects of bacteria found in pea aphid biotypes adapted to different host plants. We found that some H. defensa strains do provide protection against an aphelinid parasitoid Aphelinus abdominalis. Hamiltonella defensa from the Lotus biotype provided high resistance to A. abdominalis and moderate to low resistance to Aphidius ervi, while the reverse was seen from Medicago biotype isolates. Aphids from Ononis showed no evidence of symbiont-mediated protection against either wasp species and were relatively vulnerable to both. Our results may reflect the different selection pressures exerted by the parasitoid community on aphids feeding on different host plants, and could help explain the maintenance of genetic diversity in bacterial symbionts.
Data from: Visual landmarks sharpen grid cell metric and confer context specificity to neurons of the medial entorhinal cortex
Neurons of the medial entorhinal cortex (MEC) provide spatial representations critical for navigation. In this network, the periodic firing fields of grid cells act as a metric element for position. The location of the grid firing fields depends on interactions between self-motion information, geometrical properties of the environment and nonmetric contextual cues. Here, we test whether visual information, including nonmetric contextual cues, also regulates the firing rate of MEC neurons. Removal of visual landmarks caused a profound impairment in grid cell periodicity. Moreover, the speed code of MEC neurons changed in darkness and the activity of border cells became less confined to environmental boundaries. Half of the MEC neurons changed their firing rate in darkness. Manipulations of nonmetric visual cues that left the boundaries of a 1D environment in place caused rate changes in grid cells. These findings reveal context specificity in the rate code of MEC neurons.
Data from: Diet complementation as a frequency‐dependent mechanism conferring advantages to rare plants via dispersal
1. We used an agent-based model to test the hypothesis that diet complementation by frugivores can promote the persistence of rare plant species in communities (DCH). 2. Models simulated bird movement, frugivory, seed-dispersal, and plant recruitment on landscapes that differed in their degree of fragmentation and in their degree of fruiting species mixing at the scale of frugivores' foraging decisions. 3. Diet complementation promoted the dispersal of rare-species without the need of a priori preference from birds. The effects of landscape structure on the dispersal of rare plants were small (<5%) compared to positive effects of diet complementation because birds tracked the nutrients contained in rare fruits to balance their diets. However, resource-tracking of rare fruits increased foraging costs up to 20% of net energy intakes. 4. During post-dispersal stages, density-dependent mortality only conferred advantages to rare plants when located within hetero-specific plant patches. Still, thanks to rare-biased dispersal, rare plants showed the highest seed dispersal effectiveness irrespectively of landscape configuration. 5. Our theoretical approach presents a behavioral mechanism by which fruit choice can act as a frequency-dependent mechanism conferring rare-species advantages as important as classic post-dispersal density-dependent processes. 6. We hope that this study stimulates future work aimed at evaluating the importance of diet complementation in structuring the composition and spatial patterning of plant communities.

Moving academic conferences online: understanding patterns of delegate engagement
Scientific conferences are a key component of academic communication and development. During the COVID-19 pandemic in-person conferences are rapidly moving online, yet these virtual events may not provide the same opportunities as in-person conferences. If virtual meetings are to continue to provide effective communication and networking between researchers and stakeholders, they must be adapted to increase delegate engagement and enthusiasm. Here we present a case study of a recent medium-sized online conference. We assessed the behaviour and engagement of delegates with different components of the meeting using data from website analytics and post-conference surveys. Behaviour was variable across the available events, with talks being particularly popular but engagement with social and networking opportunities was variable. Our conclusions have been summarised in six recommendations to support future online conference organisers in enhancing engagement with their events.
Salinity Legacy: Foliar microbiome's history affects mutualist-conferred salinity tolerance
<p>The rapid human-driven changes in the environment during the Anthropocene have placed extreme stress on many plants and animals. Beneficial interactions with microorganisms may be crucial for ameliorating these stressors and facilitating the ecosystem services host organisms provide. Foliar endophytes, microorganisms that reside within leaves, are found in essentially all plants and can provide important benefits (e.g., enhanced drought tolerance or resistance to herbivory). However, it remains unclear how important the legacy effects of the abiotic stressors that select on these microbiomes are for affecting the degree of stress amelioration provided to their hosts. To elucidate foliar endophytes' role in host plant salt-tolerance, especially if salinity experienced in the field selects for endophytes that are better suited to improve salt-tolerance of their hosts, we combined field collections of 90 endophyte communities from 30 sites across the coastal Everglades with a manipulative growth experiment assessing endophyte inoculation effects on host plant performance. Specifically, we grew >350 red mangrove (Rhizophora mangle) seedlings in a factorial design that manipulated the salinity environment the seedlings experienced (freshwater vs. saltwater), the introduction of field-collected endophytes (live vs. sterilized inoculum), and the legacy of salinity stress experienced by these introduced endophytes [ranging from no salt stress (0 ppt salinity) to high salt stress (40 ppt) environments]. We found that inoculation with field-collected endophytes significantly increased mangrove performance across almost all metrics examined (15-20% increase on average) and these beneficial effects typically occurred when grown in saltwater. Importantly, our study revealed the novel result that endophyte-conferred salinity tolerance depended on microbiome salinity legacy in a key coastal foundation species. Salt-stressed mangroves inoculated with endophyte microbiomes from high salinity environments performed, on average, as well as plants grown in low-stress freshwater, while endophytes from freshwater environments did not relieve host salinity stress. Given the increasing salinity stress imposed by sea level rise and the importance of foundation species like mangroves for ecosystem services, our results indicate that consideration of endophytic associations and their salinity legacy may be critical for successful restoration and management of coastal habitats.</p>
Genome assembly of a commercial tomato hybrid (Funtelle) for haplotyping an introgression that confers TMV resistance
<p>Plant crop genome assemblies facilitate the characterization of genetically diverse cultivated and wild germplasm. </p> <p>The cultivated tomato (Solanum lycopersicum) has been improved through the introgression of genetic material from related wild species, including genetic resistance to pandemic strains of Tobacco Mosaic virus (TMV) and tomato mosaic virus (ToMV) originating from Solanum peruvianum. The exact size and the structure of the introgression from Solanum peruvianum containing the TMV/ToMV resistance gene (Tm-2^2 gene) has remained unknown, although it was known to include at least half of the physical length of chromosome 9.<br> <br> We selected a commercial cultivated tomato cultivar called Funtelle, which contains the Tm-2^2 resistance introgression in a hemizygous state, and generated Oxford Nanopore sequencing reads. Using Flye, a genome assembly tool, we assembled the reads. The assembled DNA sequences (contigs) from the Flye assembly are made available here. Subsequently, as described in detail in the associated manuscript, we made use of the assembled contigs for comprehensive haplotyping of the chromosome 9 introgression region in this commercial hybrid.<br> <br> The raw Oxford Nanopore sequencing reads of the Funtelle variety are available via the European Nucleotide Archive under project number PRJEB44956.</p>

Moving academic conferences online: aids and barriers to delegate participation
<p>In-person academic conferences are important to disseminate research and provide networking opportunities. Whether academics attend in-person conferences is based on the cost, accessibility, and safety of the event. Therefore, in-person conferences are less accessible to academics and stakeholders that are unable to overcome some of these factors, which then act as a barrier to equal and inclusive participation. Additionally, the carbon footprint of conference travel is increasingly becoming a factor in deciding on whether to attend a conference. Online conferences may provide opportunities to mitigate these challenges. Here, we illustrate how a learned society can move their conference online. Then comparing data acquired from the virtual conference and previous in-person conferences we explore the in the aids and barriers influencing the decision of delegates to attend the meetings. Ultimately, moving meetings online aids delegate participation by removing concerns about travel, cost, and carbon emissions, but there remains a barrier to participation with online meeting being perceived as less effective for networking and social opportunities.</p>
