Conserving relics from ancient underground worlds: assessing the influence of cave and landscape features on obligate iron cave dwellers from the Eastern Amazon
Jack Stanford –– Great contribution to the conservation of caves and cave faunas.
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.
The impact of different agroecological conditions on the nutritional composition of quinoa seeds
Alberto Davalos –– Quinoa is a relevant seed for human consumption. Understanding the agronomical characteristics from different varieties cultivated in different places of the world is important in order to promote their widespread cultivation.
Out of Asia: mitochondrial evolutionary history of the globally introduced supralittoral isopod Ligia exotica
Curtis Daehler –– This work provides genetic evidence suggesting the native range of a widely distributed animal that was accidentally spread by humans starting hundreds of years ago.
First endemic freshwater Gammarus from Crete and its evolutionary history—an integrative taxonomy approach
James Reimer –– A taxonomic paper with an interesting story and a solid dataset!
The little shrimp that could: phylogeography of the circumtropical Stenopus hispidus (Crustacea: Decapoda), reveals divergent Atlantic and Pacific lineages
Xavier Pochon –– This study provides the first range-wide phylogeographic study of the banded coral shrimp S. hispidus, extending across more than 27,000 km of the globe. Coalescence analysis brings evidence that an isolated Indo-Pacific lineage evolved from a rare dispersal event from the Atlantic around South Africa via the Benguela Current, thereby colonizing the Indian and Pacific Oceans, followed by dispersal across the Indo-Pacific in the last 200,000 years. Surprisingly, this benthic coral reef associated shrimp shows a single haplotype dominating the largest continuous tropical oceanic expanse on the planet.
Precopulatory behavior and sexual conflict in the desert locust
Ann Hedrick –– It describes behavior that has not previously been documented in an important pest species.
Pharmacokinetics and safety of oral glyburide in dogs with acute spinal cord injury
Minjun Chen –– This is a specific PK study in dogs and the authors have made a good experiment and report
A striking new genus and species of cave-dwelling frog (Amphibia: Anura: Microhylidae: Asterophryinae) from Thailand
Gabriela Parra Olea –– Herpetofauna from Thailand is far from being known or understood. This paper provides very important data to the field. The authors did a great job in using modern tools to evaluate the validity of the taxon and discussed it in the light of more general themes such a Biogeography and Evolution.
Repeatability of glucocorticoid hormones in vertebrates: a meta-analysis
Dany Garant –– Nice overview of published literature on the topic.
