![]() ![]() To some extent this is inevitable, given the use of species names as the pivot around which information is organised. Great strides have been made in the past decade establishing a framework for sharing data, where taxonomy and systematics has been perceived as the most prominent discipline involved. These evolutionary patterns imply that the capability to perceive various compounds during host selection was favored during adaptation to diverse host plants.īiodiversity informatics plays a central enabling role in the research community's efforts to address scientific conservation and sustainability issues. Together, our results suggest that frequent gene duplications in GRs, which might be involved in the detection of plant secondary metabolites, were associated with host range expansion in the V. We also identified two taxon-specific subfamilies of GRs, characterized by frequent lineage-specific duplications and higher non-synonymous substitution rates. cardui compared to other specialist lineages. Although the increase of the GR repertoire itself was not observed, we found that the gene birth rate of GRs was the highest in the lineage leading to V. Here, we analyzed the evolutionary dynamics of GRs among related species, including the host generalist Vanessa cardui and three specialists. Since several studies have shown associations between the repertoire sizes of chemosensory gene families and the diversity of resource use, we hypothesized that the increase in the number of genes in the GR family is associated with host range expansion in butterflies. In butterflies, gustatory receptor genes (GRs) play important roles in host plant selection by ovipositing females. ![]() The host plant range of herbivorous insects is a major aspect of insect-plant interaction, but the genetic basis of host range expansion in insects is poorly understood. The process of developing the data portal acted as a driver to implement policies necessary to encourage a culture of data sharing at the NHM. It outlines the development principles adopted for this prototypical project, which subsequently informed new digital project management methodologies at the NHM. This paper describes the technical development of the data portal, from its inception to beta launch in December 2015, its first 2 years of operation, and future plans for the project. To better serve the bespoke needs of user communities outside and within the NHM, a dedicated data portal was developed to surface these data sets and provide a sustainable platform to encourage their citation and reuse. A majority of these data were, until 2015, not widely accessible, and, even when published, were typically hard to find, poorly documented and in formats that impede discovery and integration. ![]() ![]() The Natural History Museum, London (NHM), generates and holds some of the largest global data sets relating to the biological and geological diversity of the natural world. This paper describes the implementation within the Scratchpads VRE of a new ecological interactions module that is capable of handling the needs of these projects, while at the same time is flexible to handle the needs of future projects with different data sources. In addition, the Scratchpad (Smith and Broom 2019), which already contained ecological interaction data, was migrated to the new system. Resources that can be best represented as a single table were moved to the Data Portal, while those best represented in a relational model were transferred to Scratchpads. 2019), depending on the complexity of the existing resource, as both are being sustained by the Informatics Group at the Natural History Museum, London. 2011) or to the museum's Data Portal (Scott et al. The decision was taken to migrate these to either the Scratchpads Virtual Research Environment (VRE) (Smith et al. These databases were generally bespoke software, which has increased the technical work necessary to sustain these resources. 2010) and a database of Dipterocarp Seed Predators. The Natural History Museum, London has a number of online databases that describe interactions between species, including the HOSTS database of lepidopteran host plants (Robinson et al. ![]()
