Filamentous cyanobacteria preserved in masses of fungal hyphae from the Triassic of Antarctica
Craig Moyer –– This manuscript documents the first Mesozoic cyanobacterial fossils preserved in fungal hyphal masses within a leaf-rich permineralized (silicified) peat and represents a novel finding from the Triassic of Antarctica.
Postmortem transport in fossil and modern shelled cephalopods
Kenneth De Baets –– The manuscript introduces a new metric for drift potential of cephalopod shells relevant for paleontologist and biologists. When applying it on fossil ammonoids and modern nautilids, the author demonstrates that long post-mortem drift is more than sometimes claimed and that their geographic ranges are reasonable proxies for geographic range during life making it also of great interest to biogeographers and ecologists. The results also suggest the presence modern or recently extirpated populations of Nautilus in the Indian ocean, which is of relevance for conservation efforts.
Evolutionary persistence in Gunnera and the contribution of southern plant groups to the tropical Andes biodiversity hotspot
Luis Eguiarte –– Gunnera is a genus of plants that have fascinated scientist for a long time, in particular for the very large leaves of some species and because its symbiotic relationship with the nitrogen fixing cyanobacteria Nostoc. For a many years, some botanists suspected it to be a very old, primitive genus, perhaps basal in the phylogeny of the Angiosperms. While latter molecular phylogenies did not support this position, this paper shows that indeed Gunnera is an old genus, with a complex evolutionary and phylogeographic history, and a recent radiation in the Andes. All these new results are relevant for understanding why the Neotropics have so many plant species, more than any other similar region in the planet.
Molecular phylogenetics of swimming crabs (Portunoidea Rafinesque, 1815) supports a revised family-level classification and suggests a single derived origin of symbiotic taxa
Mohammad Shamsur Rahman –– very much fantastic work in the field of taxonomy, both in classical and molecular approach!
Translating genomics into practice for real-time surveillance and response to carbapenemase-producing Enterobacteriaceae: evidence from a complex multi-institutional KPC outbreak
Nicholas Loman –– This is a really well worked example of how whole genome sequencing is transforming public health surveillance of infectious diseases.
Introgression between ecologically distinct species following increased salinity in the Colorado Delta- Worldwide implications for impacted estuary diversity
Therese Markow –– It's a first and the data are very strong/
Genome-wide identification of ABA receptor PYL family and expression analysis of PYLs in response to ABA and osmotic stress in Gossypium
Pankaj Jaiswal –– It contributes to PYL gene family annotation in cotton.
Cell wall composition and lignin biosynthetic gene expression along a developmental gradient in an Australian sugarcane cultivar
Pankaj Jaiswal –– It is an important piece of work describing the cell wall composition from an agronomic food crop that is also a potential bioenergy feedstock.
Adult zebra finches rehearse highly variable song patterns during sleep
Lesley Rogers –– Rehearsal during sleep and memory consolidation is a big issue. This is an excellent paper.
A massive update of non-indigenous species records in Mediterranean marinas
Mark Costello –– Due to the Suez Canal, the Mediterranean has more introduced species than any other sea area. However, there are often misidentifications and species suggested as "invasive" which are not (they may be rarely recorded but native). Thus a synthesis of this knowledge is timely and of wide international interest.
