- DNA sequencing efforts of environmental and other biological samples disclose unprecedented and largely untapped opportunities for advances in the taxonomy, ecology, and geographical distributions of our living world. To realise this potential, DNA-derived occurrence data (notably sequences with dates and coordinates) – much like traditional specimens and observations – need to be discoverable and interpretable through biodiversity data platforms. The Global Biodiversity Information Facility (GBIF) recently headed a community effort to assemble a set of guidelines for publishing DNA-derived data. These guidelines target the principles and approaches of exposing DNA-derived occurrence data in the context of broader biodiversity data. They cover a choice of terms using a controlled vocabulary, common pitfalls, and good practices, without going into platform-specific details. Our hope is that they will benefit anyone interested in better exposure of DNA-derived occurrence data through general biodiversity data platforms, including national biodiversity portals. This paper provides a brief rationale and an overview of the guidelines, an up-to-date version of which is maintained at https://doi.org/10.35035/doc-vf1a-nr22. User feedback and interaction are encouraged as new techniques and best practices emerge.

Fungal associates of the tree-killing bark beetle, Ips typographus, vary in virulence, ability to degrade conifer phenolics and influence bark beetle tunning behavior

- The bark beetle Ips typographus carries numerous fungi that could be assisting the beetle in colonizing live Norway spruce (Picea abies) trees. Phenolic defenses in spruce phloem are degraded by the beetle's major tree-killing fungus Endoconidiophora polonica, but it is unknown if other beetle associates can also catabolize these compounds. We compared the ability of five fungi commonly associated with I. typographus to degrade phenolic compounds in Norway spruce phloem. Grosmannia penicillata and Grosmannia europhioides were able to degrade stilbenes and flavonoids faster than E. polonica and grow on minimal growth medium with spruce bark constituents as the only nutrients. Furthermore, beetles avoided medium amended with phenolics but marginally preferred medium colonized by fungi. Taken together our results show that different bark beetle-associated fungi have complementary roles in degrading host metabolites and thus might improve this insect's persistence in well defended host tissues.

Phenotypic evolution of dispersal-enhancing traits in insular voles
- 2011

Tidskriftsartikel (refereegranskat)abstract
- Evolutionary theory predicts that in metapopulations subject to rapid extinction-recolonization dynamics, natural selection should favour evolution of traits that enhance dispersal and recolonization ability. Metapopulations of field voles (Microtus agrestis) on islands in the Stockholm archipelago, Sweden, are characterized by frequent local extinction and recolonization of subpopulations. Here, we show that voles on the islands were larger and had longer feet than expected for their body size, compared with voles from the mainland; that body size and size-specific foot length increased with increasing geographical isolation and distance from mainland; and that the differences in body size and size-specific foot length were genetically based. These findings provide rare evidence for relatively recent (less than 1000 years) and rapid (corresponding to 100-250 darwins) evolution of traits facilitating dispersal and recolonization in island metapopulations.

Rethinking the thermal melanism hypothesis: rearing temperature and coloration in pygmy grasshoppers

Tidskriftsartikel (refereegranskat)abstract
- Selection for efficient conversion of solar radiation to body heat has favored theevolution of dark coloration in many ectotherms. The thermal melanism hypothesis positsthat dark coloration is beneficial under conditions of low ambient temperatures because itresults in faster heating rates and higher body temperatures. Fast heating rates, however,may come at a cost of overheating unless compensated for by thermal physiology orbehaviour. Pygmy grasshopper (Orthoptera, Tetrigidae) populations that inhabit fire-ravagedareas characterized by blackened backgrounds and hot surface temperatures due tohigh absorbance of solar radiation show an increased frequency of black phenotypes. Iraised the progeny of wild-captured Tetrix undulata in cold and hot temperatures and useddata on color patterns and survival in a greenhouse to examine whether a cold thermalenvironment triggered the development of melanic coloration or differently affected survivalof melanic versus non-melanic individuals. My results indicate that melanism was notinfluenced by rearing temperature but by genes or epigenetic maternal effects. Temperaturealso did not affect survival. However, melanic individuals produced by melanic motherssurvived longer than melanic individuals produced by non- melanic mothers, whereas nonmelanicindividuals produced by non-black mothers survived longer than melanic individualsproduced by non-black mothers. This suggests a mismatch between color andphysiology in offspring belonging to a different color morph than their mother. Futureinvestigations into the evolution of melanism should consider conflicting selection pressureson thermal capacity and camouflage as well as the influence of correlated responsesto selection on traits associated with coloration.
