Background: Native to the Amazon region, Copaifera multijuga Hayne is a large tree (≈ 36 m in height) that is heavily exploited for extraction of its oleoresin. Many studies have addressed the phytochemical properties and applications of this raw material; however, there are few initiatives that have focused on the genetic characterization of native populations of this species. To this end, our objective was to develop microsatellite markers for C.

Objective: In some regions of the globe, accidental food confusion regarding plants can cause severe poisoning events and deaths. The aim of this study was to report on those confusions from the Marseille Poison Control Centre's (PCC) experience from 2002 to 2023.
Results: Over 22 years, 2197 food confusion events were managed with 321 different species.
The frog fauna of New Guinea is exceptionally diverse but very poorly known. Here we describe a new species of pelodryadid treefrog that is currently known only from two specimens from a single site in Hela Province in the highlands of Papua New Guinea. Genetic data show that the new species is closely related to the torrent-breeding species Litoria angiana (Boulenger, 1915) from which it can be readily distinguished by its more slender body and limbs, relatively long forelimbs, and aspects of body colouration and tuberculation.

Accurate knowledge of species distributions is foundational for effective conservation efforts. Bats are a diverse group of mammals, with important roles in ecosystem functioning. However, our understanding of bats and their ecological importance is hindered by poorly defined ranges, mostly as a result of under-recording.

Article Synopsis
- Mammalian prions are infectious proteins formed from misfolded variants of the normal prion protein (PrP), exhibiting different conformations that can self-propagate and cause various prion diseases.
- Research demonstrates that fibrillar assemblies from recombinant PrP (rPrP) derived from various species (hamster, mouse, human, and bovine) show distinct pathogenic behaviors and strain properties when tested in transgenic mice.
- The findings indicate that rPrP assemblies can be used to study the transmission of prions and their strain diversity, as they can mimic the adaptation processes of genuine prions despite lacking certain crucial amino acid regions for infectivity.
