Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

open access: yesJournal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Encystation commitment in Giardia duodenalis: a long and winding road

open access: yesParasite, 2009
Cholesterol and bile salts are relevant modulators of Giardia encystation. Although several molecules within signaling cascades have been identified, and changes in their expression observed during giardial encystation, their underlying interactions ...

Influence of prey concentration, light intensity, and temperature on the growth and ingestion of the mixotrophic dinoflagellate Pyrophacus horologium, a predator of the harmful species Heterocapsa niei

open access: yesJournal of Phycology, EarlyView.
Abstract Pyrophacus horologium belongs to the family Pyrocystaceae and was recently identified as a mixotrophic dinoflagellate capable of feeding on other dinoflagellates. In this study, the growth and feeding responses of P. horologium were investigated under various environmental conditions by providing Heterocapsa niei, its preferred prey.

Sub-pixel resolving optofluidic microscope for on-chip cell imaging [PDF]

open access: yes, 2010
We report the implementation of a fully on-chip, lensless, sub-pixel resolving optofluidic microscope (SROFM). The device utilizes microfluidic flow to deliver specimens directly across a complementary metal oxide semiconductor (CMOS) sensor to generate ...

Comparative analysis of canonical and noncanonical rhodopsins in Amphidinium carterae and Karlodinium veneficum

open access: yesJournal of Phycology, EarlyView.
Abstract Rhodopsins are ancient and versatile light‐sensitive proteins, widely distributed across microbial life. In dinoflagellates, however, their diversity and function remain poorly understood, owing to the lineage's extreme genomic divergence. Here, we surveyed the rhodopsin complements of two dinoflagellates, Amphidinium carterae and Karlodinium ...

The LARP6 La module from Tetrabaena socialis reveals structural and functional differences from plant and animal LARP6 homologues

open access: yesRNA Biology
This study identified the LARP6 La Module from Tetrabaena socialis (T. socialis), a four-celled green algae, in an effort to better understand the evolution of LARP6 structure and RNA-binding activity in multicellular eukaryotes.

Information Transfer During Food Choice in the Slime Mold Physarum polycephalum

open access: yesFrontiers in Ecology and Evolution, 2019
Throughout evolution, living systems have developed mechanisms to make adaptive decisions in the face of complex and changing environmental conditions. Most organisms make such decisions despite lacking a neural architecture.
