The discovery and characterization of protist communities from diverse environments are crucial for understanding the overall evolutionary history of life on earth. However, major questions about the diversity, ecology, and evolutionary history of protists remain unanswered, notably because data obtained from natural protist communities, especially of heterotrophic species, remain limited. In this review, we discuss the challenges associated with “field protistology”, defined here as the exploration, characterization, and interpretation of microbial eukaryotic suggestions to help fill this important gap in knowledge. We also argue that increased efforts in field studies that combine molecular and microscopical methods offer the most promising path toward (1) the discovery of new lineages that expand the tree of eukaryotes; (2) the recognition of novel evolutionary patterns and processes; (3) the untangling of ecological interactions and functions, and their roles in larger ecosystem processes; and (4) the evaluation of protist adaptations to a changing climate.

An algorithm to estimate unsteady and quasi-steady pressure fields from velocity field measurements Dabiri, John O.; Bose, Sanjeeb; Gemmell, Brad J.; Colin, Sean P.; Costello, John H. (Company of Biologists, 2013-10-10)We describe and characterize a method for estimating the pressure field corresponding to velocity field measurements such as those obtained by using particle image velocimetry. The pressure gradient is estimated from a ...
Deep-sea sediment records of the Laschamp geomagnetic field excursion (∼41,000 calendar years before present) Lund, Steve P.; Schwartz, Martha; Keigwin, Lloyd D.; Johnson, Thomas (American Geophysical Union, 2005-04-02)We have recovered two new high-resolution paleomagnetic records of the Laschamp Excursion (∼41,000 calendar years B.P.) from deep-sea sediments of the western North Atlantic Ocean. The records document that the Laschamp ...
Performance bounds on matched-field methods for source localization and estimation of ocean environmental parameters Xu, Wen (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-06)Matched-field methods concern estimation of source location and/or ocean environmental parameters by exploiting full wave modeling of acoustic waveguide propagation. Typical estimation performance demonstrates two ...
