The use of chronosequences in studies of ecological succession and soil development

open access: yes, 2010
1. Chronosequences and associated space‐for‐time substitutions are an important and often necessary tool for studying temporal dynamics of plant communities and soil development across multiple time‐scales.

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

open access: yesAdvanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

A simple protocol for cultivating the bacterivorous soil nematode Caenorhabditis elegans in its natural ecology in the laboratory

open access: yesFrontiers in Microbiology
The complex interplay between an animal and its surrounding environment requires constant attentive observation in natural settings. Moreover, how ecological interactions are affected by an animal’s genes is difficult to ascertain outside the laboratory.

Explaining the geographic origins of seasonal influenza A (H3N2) [PDF]

open access: yesarXiv, 2016
Most antigenically novel and evolutionarily successful strains of seasonal influenza A (H3N2) originate in East, South, and Southeast Asia. To understand this pattern, we simulated the ecological and evolutionary dynamics of influenza in a host metapopulation representing the temperate north, tropics, and temperate south.

Ultra–Efficient and Selective Gold Separation via Second–Sphere Coordination of Aurous Dihalide Using a Nonporous Amorphous Superadsorbent

open access: yesAdvanced Science, EarlyView.
A covalent organic superphane cage serves as a nonporous amorphous superadsorbent for highly efficient and selective gold separation. This material uniquely captures linear aurous dihalide ions, achieving exceptional uptake capacity and selectivity, and proving effective even in seawater, offering a scalable, eco–friendly solution to gold scarcity ...

EIGEN: Ecologically-Inspired GENetic Approach for Neural Network Structure Searching from Scratch [PDF]

open access: yesarXiv, 2018
Designing the structure of neural networks is considered one of the most challenging tasks in deep learning, especially when there is few prior knowledge about the task domain. In this paper, we propose an Ecologically-Inspired GENetic (EIGEN) approach that uses the concept of succession, extinction, mimicry, and gene duplication to search neural ...

Functional Divergence of Plant‐Derived Thaumatin‐Like Protein Genes in Two Closely Related Whitefly Species

open access: yesAdvanced Science, EarlyView.
Two closely related whitefly species, Trialeurodes vaporariorum and Bemisia tabaci, are found to each possess a plant‐derived TLP gene, but with entirely different functions. This finding of functional divergence challenges the notion that HGT genes maintain similar functions across species and shows that they can follow unique evolutionary paths that ...
