Creating Successful Campus Partnerships for Teaching Communication in Biology Courses and Labs
Creating and teaching successful writing and communication assignments for biology undergraduate students can be challenging for faculty trying to balance the teaching of technical content. The growing body of published research and scholarship on effective teaching of writing and communication in biology can help inform such work, but there are also local resources available to support writing within biology courses that may be unfamiliar to science faculty and instructors. In this article, we discuss common on-campus resources biology faculty can make use of when incorporating writing and communication into their teaching. We present the missions, histories, and potential collaboration outcomes of three major on-campus writing resources: writing across the curriculum and writing in the disciplines initiatives (WAC/WID), writing programs, and writing centers. We explain some of the common misconceptions about these resources in order to help biology faculty understand their uses and limits, and we offer guiding questions faculty might ask the directors of these resources to start productive conversations. Collaboration with these resources will likely save faculty time and effort on curriculum development and, more importantly, will help biology students develop and improve their critical reading, writing, and communication skills

Development of a Mobile Ecogenomic Sensor
Abstract-Modern ocean microbial research utilizes advanced molecular analytical techniques, such as polymerase chain reaction (PCR), DNA and protein probe arrays, and nucleic acid sequencing (etc.). Applying or at least initiating these techniques at the point and time of sample collection can enhance their effectiveness. To that end, in-situ sample processing and real-time molecular detection schemes have been implemented using deployable autonomous systems that can be operated in diverse ocean environments from shallow coastal waters to the deep sea. Such devices have been termed "ecogenomic sensors." The size of these instruments currently requires that they be moored in a fixed location or passively mobile, drifting at fixed depth and observing microbial communities in a moving frame of reference with ocean currents. With the highly dynamic motion of open water and microbial life, the next frontier of ocean microbial research requires the improved capability of an actively mobile asset. A mobile ecogenomic sensor encompasses a fully maneuverable vehicle with weeks of persistence, environmental data analysis, detection of physical and biological features, autonomous sampling and in situ analysis, and near-real-time data reporting. This system is now being developed by integrating three components: a compact molecular analytical instrument (the 3rd generation Environmental Sample Processor), a long-range autonomous underwater vehicle, and software algorithms for AUV-based feature detection and sampling. A summary of the system and its initial application is presented.

The definitive version was published in Harmful Algae 78 (2018): 129-141, doi:10.1016/j.hal.2018.08.006.Monterey Bay, California experiences near-annual blooms of Pseudo-nitzschia that can
affect marine animal health and the economy, including impacts to tourism and
commercial/recreational fisheries. One species in particular, P. australis, has been
implicated in the most toxic of events, however other species within the genus can
contribute to widespread variability in community structure and associated toxicity across
years. Current monitoring methods are limited in their spatial coverage as well as their
ability to capture the full suite of species present, thereby hindering understanding of
HAB events and limiting predictive accuracy. An integrated deployment of multiple in
situ platforms, some with autonomous adaptive sampling capabilities, occurred during
two divergent bloom years in the bay, and uncovered detailed aspects of population and
toxicity dynamics. A bloom in 2013 was characterized by spatial differences in Pseudo39
nitzschia populations, with the low-toxin producer P. fraudulenta dominating the inshore
community and toxic P. australis dominating the offshore community. An exceptionally
toxic bloom in 2015 developed as a diverse Pseudo-nitzschia community abruptly
transitioned into a bloom of highly toxic P. australis within the time frame of a week.
Increases in cell density and proliferation coincided with strong upwelling of nutrients.
High toxicity was driven by silicate limitation of the dense bloom. This temporal shift in
species composition mirrored the shift observed further north in the California Current
System off Oregon and Washington. The broad scope of sampling and unique platform
capabilities employed during these studies revealed important patterns in bloom
formation and persistence for Pseudo-nitzschia. Results underscore the benefit of
expanded biological observing capabilities and targeted sampling methods to capture
more comprehensive spatial and temporal scales for studying and predicting future
events.This work was

Positive and Negative Parenting in Conduct Disorder with High versus Low Levels of Callous-Unemotional Traits
Less is known about the relationship between conduct disorder (CD), callous-unemotional (CU) traits and positive and negative parenting in adolescence compared to early childhood. We combined traditional univariate analyses with a novel machine learning classifier (Angle-based Generalised Matrix Learning Vector Quantisation) to classify youth (N = 756; 9-18 years) into typically-developing (TD) or CD groups with or without elevated CU traits (CD/HCU, CD/LCU respectively) using youth- and parent-report measures of parenting behaviour. At the group level, both CD/HCU and CD/LCU were associated with high negative and low positive parenting relative to TD. However, only positive parenting differed between the CD/HCU and CD/LCU groups. In classification analyses, performance was best when distinguishing CD/HCU from TD groups and poorest when distinguishing CD/HCU from CD/LCU groups. Positive and negative parenting were both relevant when distinguishing CD/HCU from TD, negative parenting was most relevant when distinguishing between CD/LCU from TD, and positive parenting was most relevant when distinguishing CD/HCU from CD/LCU groups. These findings suggest that while positive parenting distinguishes between CD/HCU and CD/LCU, negative parenting is associated with both CD subtypes. These results highlight the importance of considering multiple parenting behaviours in CD with varying levels of CU traits in late childhood or adolescence
SARS and Pregnancy: A Case Report
We report a laboratory-confirmed case of severe acute respiratory syndrome (SARS) in a pregnant woman. Although the patient had respiratory failure, a healthy infant was subsequently delivered, and the mother is now well. There was no evidence of viral shedding at delivery. Antibodies to SARS virus were detected in cord blood and breast milk

Autonomous tracking and sampling of the deep chlorophyll maximum layer in an open-ocean eddy by a long-range autonomous underwater vehicle. IEEE Journal of Oceanic Engineering, 45(4), (2020): 1308-1321, doi:10.1109/JOE.2019.2920217.Phytoplankton communities residing in the open ocean, the largest habitat on Earth, play a key role in global primary production. Through their influence on nutrient supply to the euphotic zone, open-ocean eddies impact the magnitude of primary production and its spatial and temporal distributions. It is important to gain a deeper understanding of the microbial ecology of marine ecosystems under the influence of eddy physics with the aid of advanced technologies. In March and April 2018, we deployed autonomous underwater and surface vehicles in a cyclonic eddy in the North Pacific Subtropical Gyre to investigate the variability of the microbial community in the deep chlorophyll maximum (DCM) layer. One long-range autonomous underwater vehicle (LRAUV) carrying a third-generation Environmental Sample Processor (3G-ESP) autonomously tracked and sampled the DCM layer for four days without surfacing. The sampling LRAUV's vertical position in the DCM layer was maintained by locking onto the isotherm corresponding to the chlorophyll peak. The vehicle ran on tight circles while drifting with the eddy current. This mode of operation enabled a quasi-Lagrangian time series focused on sampling the temporal variation of the DCM population. A companion LRAUV surveyed a cylindrical volume around the sampling LRAUV to monitor spatial and temporal variation in contextual water column properties. The simultaneous sampling and mapping enabled observation of DCM microbial community in its natural frame of reference.10.13039/501100008982 - National Science Foundation
