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

open access: yesEnvironmental 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

open access: yesKnowledge 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 ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

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

open access: yesEnvironmental 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,

Identification of orb-web spider species and their food source through environmental DNA analysis

open access: yesJournal of Ecology and Environment
Spiders play a vital role in agricultural ecosystems by capturing and preying on small insects, thereby controlling the pests around crops. However, without directly collecting the specimen, it is challenging to accurately determine the species of the ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Environmental and wider economic implications of modifications to environmental tax reform [PDF]

open access: yes, 2002
The most common definition of Environmental Tax Reform (ETR) is the use of the revenue from environmental taxes to reduce distortionary labour taxes. However, the PETRAS project has shown that there are a number of social and political impediments to ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.
