How Science Suppresses the Sex Lives of Republicans
by Johnny in Ecographica
According to Utah State Representative Mike Noel, global climate change is a conspiracy theory. He insists that the whole idea of shifting climates was put together by the world’s biologists, climatologists and other scientists as an elaborate effort to control his sex life.

Tree Plantations as Biological Deserts
by Johnny in Ecographica
If I had a nickel for every time a biologist told me that tree plantations are nothing but “biological deserts” I’d be a rich man!
Well, at least a rich-er man anyway…

Arrested Development in Socratic Parasites
by Johnny in Ecographica
An irreducibly complex rant using developmental biology (arrested development) to connect the shortfalls of the Greek Philosopher Socrates to failed creationist arguments; includes a detailed account of a parasitic worm’s lifecycle (Alaria marcianae), and of course, endangered Florida Panthers and Mexican axolotls… A well rounded post!

The Poetry of the Convergent Lizards
by Johnny in Ecographica
Whiptails and fencers scurry and make haste,
cross White Sands their paths converge and pace.
Tho' differing by both origin and type,
their causal genotypes follow trace.
Independent mutations had aligned,
and were by adaptation refined.

Shield Pennywort - Hydrocotyle
by Johnny in Ecographica
Shield pennywort represents but one of about a hundred different species that belong to the Genus Hydrocotyle, a.k.a the ‘water pennyworts.’ Though often found listed as members of the Apiaceae Family, the Hydrocotyle group is now included in the ‘Ivy Family’ (Araliaceae). The genus as whole enjoys a worldwide distribution; however, the Facultative Wet H. verticillata is native to the Americas where can be found occupying floodplains, swamps, ditches, and just about any........

The Splendor of a Saprotrophic Stinkhorn
by Johnny in Ecographica
While in field last week, I encountered a species of fungus with a rather unique set of morphological and ecological characteristics. The aptly named ‘stinkhorn’ fungus (Clathrus columnatus) belongs to the Phallaceae Family of fungi and produces a distinctive gelatinous spore mass that gives off a lovely perfume. Well, lovely to insects anyway, to me it reeked of rotting meat and dung. The stinkhorn’s ‘aroma’ serves as an attractant for flies and other insects vit........ Read more »

An Imminent Creationist Feeding Frenzy, Courtesy of Nature
by Johnny in Ecographica
An article just published to Nature has turned the world of evolutionary biology topsy-turvy!Or, so they’d like us to believe…The paper’s authors Chris Venditti, Andrew Meade and Mark Pagel have devised a new model that shows that evolution is not driven by natural selection or through the accumulative effects of random genetic drift. Rather than incremental and gradual change, their study suggests that the vast bulk of speciation results from rare stochastic events. They call this new the........ Read more »

Wetland Plant of the Week #37
by Johnny in Ecographica
Helianthus angustifolius is a branched perennial plant that is native to North America. This Facultative Wet species can found in hydric flatwoods and marsh communities as well as along the sides of ditches and roads that have mesic to saturated soils. Its brilliantly colored disk flowers make it easily recognizable as a member of the Asteraceae’s sunflower group – the Genus Helianthus. The swamp sunflower’s tall domesticated cousin, ‘the’ sunflower Helianthus an........ Read more »

What an Unlearned Presidential Hopeful can teach us about Evolution
by Johnny in Ecographica
One of the common misconceptions about biological evolution is that the process pushes organisms towards a pinnacle of perfection in which the ‘most evolved species’ maintain dominance over ‘less evolved’ or ‘lower organisms.’ Often closely associated with this mistaken belief is the erroneous idea that, by virtue of braininess, our own species – Homo sapiens - currently holds sovereignty over evolution’s hypothetical pinnacle. These egocentric a........ Read more »
