Word of the Month: Myrmecomorphy
by Kevin Zelnio in EvoEcoLab
Myrmecomorphy Part of the fun in natural history is playing word detective! Naturalists speak in greek and latin and love mashing together parts of these languages to create new, yet often very descriptive, words. This month, I want to talk a little about an awesome word – MYRMECOMORPHY. This beauteous etymological wonder is derived from from the root [...]

Prescribing Gene Flow
by Kevin Zelnio in EvoEcoLab
When ecosystems are sick, who prescribes the cure? Its not as straight-forward as it is in medicine. A doctor diagnoses a problem and prescribes some medication or treatments to ease the pain or kill infectious agents. Sometimes we battle the insurance agents over the necessity of treatments. This is simplified of course. In applied ecology, [...]

The Reality and Utility of Bear Paternity Tests
by Kevin Zelnio in EvoEcoLab
It was summer of 2008 and the rhetoric was getting as hot as a globally warmed hood on a ’91 Chevy Camaro RS (my 2nd car, with t-tops of course). While you might fry an egg on the hood, you could broil a few cornish hens on the hot tin roof that encapsulated the election [...]

Whale Bone-Devouring Worm Into More Than Just Whales
by Kevin Zelnio in Deep Sea News
We have a long history of being HUGE fans of the “bone-devouring zombie worm from hell”. Osedax species were described less than 10 years ago and much work on their reproduction, evolution and ecology has yielded incredible insights into a unique and bizarre way of life!

From the Editor’s Desk: The Grand Challenge of Ocean Acidification and Fisheries
by Kevin Zelnio in Deep Sea News
Anthropogenic climate change has been hypothesized for centuries (discussed in Le Treut 2007) before the careful measurements of scientists in the mid-20th century. From 1833 to 1997, Stanhill (2001) calculated that the climate change science doubled every 11 years. The impact of carbon dioxide concentrations in the ocean was recognized early on with measurements and . . . → Read More: From the Editor’s Desk: The Grand Challenge of Ocean Acidification and Fisheries...

Barnacle Evolution I: Phylogeny Served Without Plates

Barnacle evolution was recently rewritten by a large effort of Perez-Losada and colleagues in 2008. Using a combination of genes and morphological traits they rejected some of the ideas that were foundational to barnacle biology and taxonomy, while giving new support for other ideas.

Confronting Climate Contrarianism II: Methane Accumulation in the Atmosphere
by Kevin Zelnio in Deep Sea News
Confronting Climate Contrarianism looks into the claims made climate contrarians and how they (mis)use the scientific literature.
—————————————————————–
In a textbook example of climate contrarians misusing the primary literature for an anti-scientific agenda, Robinson et al. (2007) are seemingly flippant about decades of research showing how humans have affected the climate since the onset of the Industrial Revolution. . . . → Read More: Confronting Climate Contrarianism II: Methane Accumulation in the Atmosphere...

New Fossil Anemone Reveals Innard Secrets

Continuing its trend as one of the top destinations for out-of-this-world fossil finds, China is yielding yet another piece to the evolutionary jigsaw puzzle.

Sea Squirts, SLOSS, and Sex

Long time readers will know how perverse and socially inappropriate the unseemly sea squirt is. But there is an interesting property of sea squirt pornography and local oceanography that may have consequences in the debates surrounding marine reserve design.

Assassin Bugs Use Their Victims as Shields
by Kevin Zelnio in The Online Laboratory of Kevin Zelnio
When we think of ‘prey’ we generally think of nourishment, but prey has other use too.

Masking to avoid [...]... Read more »

Penguins Immediately Benefit From MPA

There is much buzz these days about marine protected areas (MPAs) and no-take zones. We are approaching the age of assessment. There has been enough time passed where we should see a signal of improvement to verify conservation theory. While the data has been trickling in for many MPAs and there is in general an improvement . . . → Read More: Penguins Immediately Benefit From MPA... Read more »

First New Snail Larval Form Discovered Since 1878

Yicaris – Progenitor of the Crustacea
by Kevin Zelnio in Deep Sea News
Finding any new fossil is rare. Finding invertebrate fossils is made even more rare because of the squishy nature of most invertebrates. Sometimes the wandering paleontologist, toiling away with utmost care through dust and debris, can find parts of squishy invertebrates like scolodonts (polychaete jaws), coral rubble, carbonate shell cement, or maybe sea star or sponge . . . → Read More: Yicaris – Progenitor of the Crustacea...
