Intruder (DD38E), a recently evolved sibling family of DD34E/Tc1 transposons in animals

Mobile DNA, 2020
Background A family of Tc1/mariner transposons with a characteristic DD38E triad of catalytic amino acid residues, named Intruder (IT), was previously discovered in sturgeon genomes, but their evolutionary landscapes remain largely unknown. Results Here,

Benchmarking the Taxonomic Resolution of Fish eDNA Metabarcodes Against COI Barcodes

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Even though environmental DNA metabarcoding is revolutionizing biomonitoring, many critical steps remain unstandardized, leading to arbitrary choices, particularly regarding the selection of metabarcode, clustering method and similarity threshold, among others.

Fast, Flexible, Feasible: A Transparent Framework for Evaluating eDNA Workflow Trade‐Offs in Resource‐Limited Settings

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Environmental DNA (eDNA) analysis enables biodiversity monitoring by detecting organisms from trace genetic material, but high reagent costs, cold‐chain logistics and computational demands limit its broader use, particularly in resource‐limited settings.

Ontogeny and potential function of poacher armor (Actinopterygii: Agonidae)

Journal of Morphology, 2020
AbstractMany vertebrates are armored over all or part of their body. The armor may serve several functional roles including defense, offense, visual display, and signal of experience/capability. Different roles imply different tradeoffs; for example, defensive armor usually trades resistance to attack for maneuverability.

Non‐invasive reconstruction of complete mitochondrial genomes from aquatic environmental DNA using PCR‐free long‐read sequencing

Methods in Ecology and Evolution, Volume 17, Issue 1, Page 99-110, January 2026.
Abstract Environmental DNA (eDNA) enables non‐invasive assessment of aquatic biodiversity. Because eDNA is typically diluted and fragmented, most applications rely on short mitochondrial amplicons, which often fail to resolve closely related species and do not support individual‐level inference. However, intact or near‐full‐length mitochondrial genomes
