Investigation of floristic similarities between Taiwan and terrestrial ecoregions in Asia using GBIF data

Botanical Studies, 2017
Background Floristic compositions of non-endemic plants of continental islands were related to the neighboring continents because non-endemic plant species had historically migrated to continental islands from source areas.

High unexpected genetic diversity of a narrow endemic terrestrial mollusc [PDF]

PeerJ, 2017
The Iberian Peninsula has an extensive record of species displaying strong genetic structure as a result of their survival in isolated pockets throughout the Pleistocene ice ages. We used mitochondrial and nuclear sequence data to analyze phylogeographic

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont

Angewandte Chemie, EarlyView.
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

Artificial intelligence reveals environmental constraints on colour diversity in insects

Nature Communications, 2019
Deep learning has the potential to identify ecological relationships between environment and complex phenotypes that are difficult to quantify. Here, the authors use deep learning to analyse associations among elevation, climate and phenotype across ...

Weak gene–gene interaction facilitates the evolution of gene expression plasticity

BMC Biology, 2023
Background Individual organisms may exhibit phenotypic plasticity when they acclimate to different conditions. Such plastic responses may facilitate or constrain the adaptation of their descendant populations to new environments, complicating their ...

Gapless Complete Genome and Multi‐Omics Illuminate Immune Adaptation and Host‐Virus Interactions in a Coronavirus Reservoir

Advanced Science, EarlyView.
We present a complete T2T genome assembly for a key bat reservoir. Integrating population genomics, comparative genomics, transcriptomics, single‐cell omics, and functional assays, we resolve previously inaccessible genomic regions and identify evolutionary signatures associated with immune adaptation.

Voluntary Collective Action to Address Growing Agricultural Challenges in Two Countries: Experimental Insights and Commonalities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We conducted two framed field economic experiments with citrus farmers in Florida, United States and soybean farmers in Argentina to investigate their willingness to coordinate pest and weed management efforts. Despite the contrast between these two agricultural contexts, we find striking behavioral commonalities.

First record of the genus Eulocastra Butler, 1886 (Lepidoptera, Noctuidae) from the Indochina Peninsula, with notes on the distribution and host associations of Eulocastra sasakii Sugi, 1985 [PDF]

Biodiversity Data Journal
Eulocastra sasakii Sugi, 1985 (Lepidoptera, Noctuidae) was previously known only from Japan and has, therefore, been regarded as a Japanese endemic species. The species is considered threatened in Japan and is currently listed as Vulnerable (Category II)

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...
