Ants contribute to pollination but not to reproduction in a rare calcareous grassland forb
Curtis Daehler –– Experiments demonstrate that although ants are frequent floral visitors and they carry pollen, they are not effective pollinators and they may even be detrimental to reproduction in a rare plant.
Optimization of antioxidative peptides from mackerel (Pneumatophorus japonicus) viscera
Carlos Conte-Junior –– There are few papers that explore fish products.
Catchment land use predicts benthic vegetation in small estuaries
Jonathan Tonkin –– The authors find that converting as little as 20% of a catchment to fertilized land can shift estuarine vegetation from seagrass to macroalgae dominated. They find that simple land use measures – in this case, % fertilized land – may act as strong indicators of eutrophication risk to estuaries.
A new slider turtle (Testudines: Emydidae: Deirochelyinae: Trachemys) from the late Hemphillian (late Miocene/early Pliocene) of eastern Tennessee and the evolution of the deirochelyines
Andrew Farke –– Describes a new fossil species from a group of turtles that are ecologically important in North America today.
A simple molecular technique for distinguishing species reveals frequent misidentification of Hawaiian corals in the genus Pocillopora
Xavier Pochon –– This study developed a simple and cost-effective assay that quickly allows for discrimination amongst coral species in the genus Pocillopora using simple PCR amplification followed by digestion with widely available restriction enzymes. Pocilloporid corals exhibit extreme phenotypic plasticity, making morphological identification of species very challenging. The assay was tested on 691 coral samples collected from across the Hawaiian Archipelago and successfully characterised all six Pocillopora species occurring in Hawaii. Compared to sequence-based identification, this method is simple, rapid and represents a cost saving of nearly 95%. This work will benefit future studies of population structure, ecology, biodiversity, evolution and conservation in this challenging coral genus.
Forecasting biodiversity in breeding birds using best practices
James Roper –– Over time, too many models have been applied under the assumption that they are effective without adequately testing whether they indeed do predict anything. This paper illustrates the issues with that approach and lays down a framework under which future models may be developed and tested.
Differential gene expression during early development in recently evolved and sympatric Arctic charr morphs
Marc Robinson-Rechavi –– This study allows to link natural variation in morphology with genetic divergence in expression patterns, thus helping link ecology to molecular genomics.
An Indo-Pacific damselfish (Neopomacentrus cyanomos) in the Gulf of Mexico: origin and mode of introduction
Donald Kramer –– Although only dealing with a single invasive species, it is a very thorough and interesting analysis of the potential for oil rigs to move fish (and potentially other marine species) around the world.
Moving to 3D: relationships between coral planar area, surface area and volume
Ronaldo Francini-Filho –– Tech tools for coral reef research are emerging fast and boosting science
Evaluating the adaptive evolutionary convergence of carnivorous plant taxa through functional genomics
Todd Vision –– This is a novel and innovative approach to studying the genomic correlates of convergent evolution. It is likely to inspire similar studies in other systems and for other kinds of genomic changes, as well as bioinformatic work to refine and extend the methods.
