Data from: AmpuBase: a transcriptome database for eight species of apple snails (Gastropoda: Ampullariidae)

Jack C. H. Ip, Huawei Mu, Qian Chen, Jin Sun, Santiago Ituarte, Horacio Heras, Bert Van Bocxlaer, Monthon Ganmanee, Xin Huang & Jian-Wen Qiu
Background: Gastropoda, with approximately 80,000 living species, is the largest class of Mollusca. Among gastropods, apple snails (family Ampullariidae) have members that are widely distributed in tropical and subtropical freshwater ecosystems and are ecologically and economically important. They exhibit various morphological and physiological adaptations to their respective habitats, which make them ideal candidates for studying adaptation, population divergence, speciation, and larger-scale patterns of diversity, including biogeography of native and invasive populations. The limited availability of...

Climatic and Vegetational Drivers of Insect Beta Diversity at the Continental Scale

Douglas Chesters, Douglas Chesters, Philip Beckschäfer, Michael Orr, Sarah Adamowicz, Kwok-Pan Chun & Chao-Dong ZHU
Aim We construct a framework for mapping pattern and drivers of insect diversity at the continental scale, and use it to test whether and which environmental gradients drive insect beta diversity. Location Global; North and Central America; Western Europe Time period 21st century Major taxa studied Insects Methods An informatics system was developed to integrate terrestrial data on insects with environmental parameters. We mined repositories of data for distribution, climatic data was retrieved (WorldClim), and...

Data from: Adaptation to deep-sea chemosynthetic environments as revealed by mussel genomes

Jin Sun, Yu Zhang, Ting Xu, Yang Zhang, Huawei Mu, Yanjie Zhang, Yi Lan, Christopher J. Fields, Jerome H. L. Hui, Wei-Peng Zhang, Runsheng Li, Wenyan Nong, Fiona K. M. Cheung, Jian-Wen Qiu & Pei-Yuan Qian
Hydrothermal vents and methane seeps are extreme deep-sea ecosystems that support dense populations of specialised macrobenthos such as mussels. But lack of genome information hinders understanding of the adaptation of these animals to such inhospitable environment. Here we report the genomes of a deep-sea vent/seep mussel Bathymodiolus platifrons and a shallow-water mussel Modiolus philippinarum. Phylogenetic analysis shows that these mussel species diverged approximately 110.4 million years ago. Many gene families, especially those for stabilising protein...

Data from: DIY meteorology: use of citizen science to monitor snow dynamics in a data-sparse city

Willemijn M. Appels, Lori Bradford, Kwok Pan Chun, Anna E. Coles & Graham Strickert
Cities are under pressure to operate their services effectively and project costs of operations across various timeframes. In high-latitude and high-altitude urban centers, snow management is one of the larger unknowns and has both operational and budgetary limitations. Snowfall and snow depth observations within urban environments are important to plan snow clearing and prepare for the effects of spring runoff on cities’ drainage systems. In-house research functions are expensive, but one way to overcome that...

Data from: Signatures of divergence, invasiveness and terrestralization revealed by four apple snail genomes

Jin Sun, Huawei Mu, Jack C. H. Ip, Runsheng Li, Ting Xu, Alice Accorsi, Alejandro Sánchez Alvarado, Eric Ross, Yi Lan, Yanan Sun, Alfredo Castro-Vazquez, Israel A. Vega, Horacio Heras, Santiago Ituarte, Bert Van Bocxlaer, Kenneth A. Hayes, Robert H. Cowie, Zhongying Zhao, Yu Zhang, Pei-Yuan Qian & Jian-Wen Qiu
The family Ampullariidae includes both aquatic and amphibious apple snails. They are an emerging model for evolutionary studies due to the high diversity, ancient history and wide geographical distribution. Insight into drivers of ampullariid evolution is hampered, however, by the lack of genomic resources. Here we report the genomes of four ampullariids spanning the Old World (Lanistes nyassanus) and New World (Pomacea canaliculata, Pomacea maculata and Marisa cornuarietis) clades. The ampullariid genomes have conserved ancient...

Data from: De novo assembly of the transcriptome of an invasive snail and its multiple ecological applications

Jin Sun, Mingling Wang, Hao Wang, Huoming Zhang, Xianglong Zhang, Vengatesen Thiyagarajan, Pei-Yuan Qian, Jian-Wen Qiu, J. W. Qiu & P. Y. Qian
Studying how invasive species respond to environmental stress at the molecular level can help us assess their impact and predict their range expansion. Development of markers of genetic polymorphism can help us reconstruct their invasive route. However, to conduct such studies requires the presence of substantial amount of genomic resources. This study aimed to generate and characterize genomic resources using high throughput transcriptome sequencing for Pomacea canaliculata, a non-model gastropod indigenous to Argentina that has...

Data from: Why we need more nature at work: effects of natural elements and sunlight on employee mental health and work attitudes

Mihyang An, Stephen M. Colarelli, Kimberly O'Brien & Melanie E. Boyajian
This study investigated the effects of natural elements and direct and indirect sunlight exposure on employee mental health and work attitudes. We recruited participants via an online panel from the United States and India, and analyzed data from 444 employees. Natural elements and sunlight exposure related positively to job satisfaction and organizational commitment, and negatively to depressed mood and anxiety. Direct sunlight was a dominant predictor of anxiety; indirect sunlight was a dominant predictor of...

Data from: Understanding the transition from water to land: insights from multi-omic analyses of the perivitelline fluid of apple snail eggs

Jack C.H. Ip, Huawei Mu, Yanjie Zhang, Jin Sun, Horacio Heras, Ka Hou Chu & Jian-Wen Qiu
Most gastropods deposit their eggs either on land or underwater, but the family Ampullariidae includes members that exhibit both underwater and aerial oviposition, making it an ideal model for understanding mechanisms underlying the evolutionary transition from water to land. We applied SDS-PAGE and LC-MS/MS to analyse the proteome of the egg perivitelline fluid (PVF) of Marisa cornuarietis – an aquatic ovipositing ampullariid. Comparison with the reported PVF proteomes of two aerial ovipositing ampullariids (Pomacea canaliculata...

Large-scale metabolic interaction network of the mouse and human gut microbiota

Roktaek Lim, Josephine Jill T. Cabatbat, Thomas L. P. Martin, Haneul Kim, Seunghyeon Kim, Jaeyun Sung, Cheol-Min Ghim & Pan-Jun Kim
The role of our gut microbiota in health and disease is largely attributed to the collective metabolic activities of the inhabitant microbes. A system-level framework of the microbial community structure, mediated through metabolite transport, would provide important insights into the complex microbe-microbe and host-microbe chemical interactions. This framework, if adaptable to both mouse and human systems, would be useful for mechanistic interpretations of the vast amounts of experimental data from gut microbiomes in murine animal...
