Between The Lashes of Your Eyes

“Re-examine all you have been told at school or church or in any book, dismiss whatever insults your own soul; and your very flesh shall be a great poem, and have the richest fluency, not only in its words, but in the silent lines of its lips and face, and between the lashes of your eyes, and in every motion and joint of your body.”

Walt Whitman, Leaves of Grass

Backcountry with a view! [Explored] by Steve Flowers on Flickr.

So if someone comes and visits me we can go climb up to blue lakes. Half day hike and backpack and climb around the area. Sneffles peak is just to the right of this pic and its a colorado 14ner.

siphonophora:

Diatoms are a major group of typically unicellular algae, and are one of the most common varieties of phytoplankton. Unique to diatoms, their cells are encased in a cell wall of silica (silicon dioxide), which is responsible for their crystalline appearance. Diatoms are autotrophic, meaning they derive their nutrition from their surroundings by means of photosynthesis or chemosynthesis. This places them in the role of producers in the food chain.

Classification:
Eukaryota > Chromalveolata > Heterokontophyta > Bacillariophyceae

The impact of climate change on the structure of Pleistocene food webs across the mammoth steppe

by Justin D. Yeakel, Paulo R. Guimarães Jr, Hervé Bocherens and Paul L. Koch

“Species interactions form food webs, impacting community structure and, potentially, ecological dynamics. It is likely that global climatic perturbations that occur over long periods of time have a significant influence on species interaction patterns. Here, we integrate stable isotope analysis and network theory to reconstruct patterns of trophic interactions for six independent mammalian communities that inhabited mammoth steppe environments spanning western Europe to eastern Alaska (Beringia) during the Late Pleistocene. We use a Bayesian mixing model to quantify the contribution of prey to the diets of local predators, and assess how the structure of trophic interactions changed across space and the Last Glacial Maximum (LGM), a global climatic event that severely impacted mammoth steppe communities. We find that large felids had diets that were more constrained than those of co-occurring predators, and largely influenced by an increase in Rangifer abundance after the LGM. Moreover, the structural organization of Beringian and European communities strongly differed: compared with Europe, species interactions in Beringian communities before—and possibly after—the LGM were highly modular. We suggest that this difference in modularity may have been driven by the geographical insularity of Beringian communities” (read more/not open access).
