Invasive species that undergo a founder event may experience a decline in genetic diversity yet still establish successful populations. A possible example is a population of the common wall lizard ( Podarcis muralis ) in Cincinnati, Ohio, USA, which was founded following an introduction in the 1950s of a small number of individuals from Europe. We used whole genome sequences of individuals from source and introduced population...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Dispersal patterns of sandfish (Holothuria scabra) larvae in Manus Province, Papua New GuineaOA Marine
In many tropical nations, coastal communities seek to manage their sea cucumber fisheries by establishing locally managed marine areas on their traditional fishing grounds. These managed areas can protect spawning stocks, however the extent to which they help to replenish nearby sea cucumber fisheries is debated, as nothing is known about the scales at which sea cucumber larvae disperse. In this study, we used genetic parentag...
A rich source of new therapeutics are natural products derived from modular non-ribosomal peptide synthetases (e. g. penicillins, daptomycin). Yet, efficient bioengineering of these often gigantic megaenzymes to generate natural product analogs is a major challenge. Using synthetic zippers, we have established a co-expression strategy that not only simplifies bioengineering, but rapidly increases the biocombinatorial potential...
Pro- and anti-inflammatory macrophages express a sub-type specific purinergic receptor profileNARA Subscribed
Extracellular nucleotides act as danger signals that orchestrate inflammation by purinergic receptor activation. The expression pattern of different purinergic receptors may correlate with a pro- or anti-inflammatory phenotype. Macrophages function as pro-inflammatory M1 macrophages (M1) or anti-inflammatory M2 macrophages (M2). The present study found that murine bone marrow-derived macrophages express a unique purinergic rec...
Key message β-Carotene content in sweetpotato is associated with the Orange and phytoene synthase genes; due to physical linkage of phytoene synthase with sucrose synthase , β-carotene and starch content are negatively correlated. Abstract In populations depending on sweetpotato for food security, starch is an important source of calories, while β-carotene is an important source of provitamin A. The negative association betwee...
Cyclo(tetrahydroxybutyrate) production is sufficient to distinguish between Xenorhabdus and Photorhabdus isolates in ThailandNARA Subscribed
Summary Bacteria of the genera Photorhabdus and Xenorhabdus produce a plethora of natural products to support their similar symbiotic life cycles. For many of these compounds, the specific bioactivities are unknown. One common challenge in natural product research when trying to prioritize research efforts is the rediscovery of identical (or highly similar) compounds from different strains. Linking genome sequence to metabolit...
Photorhabdus ‐nematode symbiosis is dependent on hfq ‐mediated regulation of secondary metabolitesNARA Subscribed
Summary Photorhabdus luminescens maintains a symbiotic relationship with the nematodes Heterorhabditis bacteriophora and together they infect and kill insect larvae. To maintain this symbiotic relationship, the bacteria must produce an array of secondary metabolites to assist in the development and replication of nematodes. The regulatory mechanisms surrounding production of these compounds are mostly unknown. The global post‐...
Large‐scale, multidirectional larval connectivity among coral reef fish populations in the Great Barrier Reef Marine ParkNARA Subscribed
Larval dispersal is the key process by which populations of most marine fishes and invertebrates are connected and replenished. Advances in larval tagging and genetics have enhanced our capacity to track larval dispersal, assess scales of population connectivity, and quantify larval exchange among no‐take marine reserves and fished areas. Recent studies have found that reserves can be a significant source of recruits for popul...
