Hot Topic Article: Variability of marine climate on the North Icelandic Shelf in a 1357-year proxy archive based on growth increments in the bivalve Arctica islandica.

This interesting paper by an international team of scientists utilizes accurate aging of the bivalve Arctic islandica to track and age changes in the North Icelandic benthic environment over the last 1300-plus years. As part of the research the scientists have worked with a number of incredibly long-lived animals, some over 300 years of age,  Read More

Hot Topic Article: An unusual cuticular tumor-like growth on the abdomen of a lobster, Homarus americanus.

This interesting case report by two researchers from the Virginia Institute of Marine Science provides details of an unusual crustacean tumor called a hamartoma. This is the first reported case of such a neoplasm in a lobster and only the second crustacean hamartoma on record. The authors hypothesize that the tumor resulted from wound  Read More

Hot Topic Article: Winter Loss Survey 2012 – 2013: Preliminary Results: Preliminary Results: Honey Bee Colony Losses in the United States, Winter 2012-2013.

A multi-institutional group of experts provide a summary of preliminary results on honey bee colony losses this past winter. While the 2012-2013 losses (approx. 31% of over 2.6 million colonies) ) exceeded those of the previous winter by over 40% they were consistent with the average colony loss since the winter of 2006-2007. Most professional beekeepers consider a 15%  Read More

Hot Topic Article: Disposable penis and its replenishment in a simultaneous hermaphrodite.

Ayami Sekizawa of the Department of Biology and Geosciences, Osaka City University, Osaka Japan and colleagues have discovered that a species of nudibranch can autotomize its penis after copulating, and via "penis replenishment," is able to
copulate again in less than 24 hours. Following copulation penis autotomy occurred within 30 minutes. The authors observed and recorded over 30 reciprocal copulations for this study. Like many gastropods, Chromodoris reticulata is a simultaneous hermaphrodite, but this mating  Read More

Hot Topic Article: Differential expression of American lobster (Homarus americanus) immune related genes during infection of Aerococcus viridans var. homari, the causative agent of Gaffkemia

The American lobster is the most economically important fishery in Canadian Atlantic Ocean waters. This interesting article describes the first broad attempt at characterizing the American lobster's immunological genetic make-up by identifying thousands of genes from the lobster hepatopancreas. The authors then focused on 148 genes involved in the immune response to an in vivo  Read More
