Rediscovering the lost: eDNA detection of freshwater decapods on Réunion Island

Knowledge and Management of Aquatic Ecosystems
Freshwater ecosystems on tropical oceanic islands host unique biodiversity. On Réunion Island, freshwater decapod crustaceans are key indicators of ecosystem health, yet their distribution and conservation status remain poorly documented.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Comparative analysis of diet composition and gut parasite diversity in bar-headed geese and ruddy shelducks using environmental dna metabarcoding [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi
We comprehensively analyzed the dietary preferences and intestinal parasite diversity of two waterbirds, the Ruddy shelduck (Tadorna ferruginea) and the Bar-headed goose (Anser indicus), using environmental DNA metabarcoding with the 18S rDNA V9 (for ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

A qPCR Assay for the Threatened Pilbara Olive Python (Liasis olivaceus barroni)

Environmental DNA
The Pilbara olive python (Liasis olivaceus barroni) is endemic to the Pilbara region of Western Australia and listed as threatened. Despite being a priority conservation target, they are difficult to monitor as their cryptic nature complicates ...

Genomic resources for the monitoring and management of Tometes trilobatus, Hoplias aimara and Myloplus rhomboidalis, three exploited freshwater fish species in French Guiana

Knowledge and Management of Aquatic Ecosystems
The Neotropical region, hosts a quarter of all freshwater fish species, while providing important food resources for local human populations. The management of neotropical freshwater ecosystems is thus of primary importance for both biodiversity ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Evaluation of Extraction Methods for the Recovery of Vertebrate DNA From Spider Webs

Environmental DNA
Spider webs have recently been recognized as an excellent source of vertebrate eDNA. Here we compare four sample preparation methods and three commercially available DNA extraction kits to optimize vertebrate eDNA recovery. We assessed DNA yield, purity,
