Genomic Signatures of Influenza A Pandemic (H1N1) 2009 Virus

Emerging Infectious Diseases, 2009
Adaptive mutations that have contributed to the emergence of influenza A pandemic (H1N1) 2009 virus, which can replicate and transmit among humans, remain unknown.

Multi-species count transformation models [PDF]

arXiv, 2022
By extending single-species distribution models, multi-species distribution models and joint species distribution models are able to describe the relationship between environmental variables and a community of species. It is also possible to model either the marginal distribution of each species (multi-species models) in the community or their joint ...

Divergence of Fecal Microbiota and Their Associations With Host Phylogeny in Cervinae

Frontiers in Microbiology, 2018
Gastrointestinal microbiota may shape the adaptation of their hosts to different habitats and lifestyles, thereby driving their evolutionary diversification.

Evolutionary Limitation and Opportunities for Developing tRNA Synthetase Inhibitors with 5-Binding-Mode Classification

Life, 2015
Aminoacyl-tRNA synthetases (aaRSs) are enzymes that catalyze the transfer of amino acids to their cognate tRNAs as building blocks for translation. Each of the aaRS families plays a pivotal role in protein biosynthesis and is indispensable for cell ...

Host-adaptation of the rare Enterocytozoon bieneusi genotype CHN4 in Myocastor coypus (Rodentia: Echimyidae) in China

Parasites & Vectors, 2020
Background Enterocytozoon bieneusi is a zoonotic gastrointestinal pathogen and can infect both humans and animals. The coypu (Myocastor coypus) is a semi-aquatic rodent, in which few E.

The theory of games and microbe ecology [PDF]

Theor. Ecol. 12, 1-15 (2019), 2020
Using game theory we provide mathematical proof that if a species of asexually reproducing microbes does not possess maximum variability in competitive abilities amongst its individual organisms, then that species is vulnerable to replacement by competitors.

Plant abundance, but not plant evolutionary history, shapes patterns of host specificity in foliar fungal endophytes

Ecosphere, 2022
Understanding the origins and maintenance of host specificity, or why horizontally‐acquired symbionts associate with some hosts but not others, remains elusive.

Symbiotic Culture of Three Closely Related Dendrobium Species Reveals a Growth Bottleneck and Differences in Mycorrhizal Specificity at Early Developmental Stages

Diversity, 2022
Mycorrhizal specificity, i.e., the range of fungi allowing mycorrhizal partnerships, differs among orchid species, but that at early developmental stages is unclear.

Birds of a Feather: Capturing Avian Shape Models from Images [PDF]

arXiv, 2021
Animals are diverse in shape, but building a deformable shape model for a new species is not always possible due to the lack of 3D data. We present a method to capture new species using an articulated template and images of that species. In this work, we focus mainly on birds.
