Exploring the cyanobacterial diversity in Portugal: Description of four new genera from LEGE-CC using the polyphasic approach.

Culture collections such as the Blue Biotechnology and Ecotoxicology Culture Collection (LEGE-CC) hold approximately 1200 cyanobacterial strains and are critical community resources. However, many isolates in this and other collections have not been described with a polyphasic approach, and this limits further study. Here, we employed a polyphasic methodology that integrates 16S rRNA gene phylogenetic analyses, similarity (p-distance), 16S-23S ITS rRNA region secondary structures, morphological analyses, and habitat assessments to describe four novel cyanobacterial genera from the LEGE-CC, Portugal.

Is bedding material a more effective thermal insulator than trap cover for small mammal trapping? A field experiment.

Live trapping is a key technique for conducting ecological studies on small mammals. All-metal live traps are popular in monitoring schemes owing to their tested performance, lightweight design (aluminium) and foldability. However, capture represents a stressful situation for small mammals, particularly during cold seasons, when individuals are susceptible to cold weather starvation resulting from low temperature and insufficient food to maintain body temperature.

The role of the perioperative prone position in the low recurrence of pressure injuries in the pelvic region.

Objective: A pressure injury (PI) is a localised area of damage to the skin and/or underlying soft tissue as a result of a sustained mechanical loading. There are three key aetiological mechanisms to PI formation-direct cell deformation, inflammatory oedema and ischaemic damage-which are typically activated sequentially to drive a spiral of injury. This article discusses the role of the perioperative prone position as a rational approach to reducing the recurrence of pelvic PI after reconstructive surgery.
