Use of multi-modelling methods to inform conservation and reintroductions of pine marten in Britain.

The successful onset of recovery of the European pine marten () in some parts of Britain through range expansion and, more recently translocation for reintroductions, has resulted in a strong interest in reintroduction projects throughout the country. However, the geographic scope and conservation goals of these initiatives are often local and lack consideration of how they fit within the wider context of national-scale pine marten conservation. Here, we aim to maximize conservation benefit strategically at a national level by developing a simple, transparent, and transferable framework based on landscape modelling methods and spatially explicit population viability analyses.

Blocking microtubule deacetylation inhibits anaphase chromosome movements in crane-fly spermatocytes.

Chromosome movement speeds during anaphase are regulated by depolymerization of microtubules. Several models describe chromosome movement during cell division but none of them consider post-translational modifications of tubulin, even though such modifications help specify microtubules for unique cellular activities. Among these modifications, acetylation of Lysine 40 is one of the common post-translational modifications.

Robotic and Laparoscopic Adrenalectomy for Pheochromocytoma: An International Multicenter Study.

Background And Objective: Robotic adrenalectomy (RA) has attracted interest as an alternative to laparoscopic adrenalectomy (LA) for patients with pheochromocytoma, although its beneficial effects are uncertain. Our aim was to compare RA and LA outcomes for these patients.

Methods: Data for patients who underwent RA or LA for pheochromocytoma in 46 international centers between 2012 and 2022 were reviewed.

The effects of winter cold on acute copper bioaccumulation and toxicity in brook char (Salvelinus fontinalis).

Freshwater fish that are acutely exposed to copper (Cu) can experience disturbances of ion regulation and ammonia excretion. Temperature has been shown to affect Cu bioaccumulation and toxicity in fish, but the focus has largely been on warm temperature effects. Yet, acclimation of freshwater fish to near-freezing temperatures encountered during the winter of temperate regions can challenge fish condition and physiology, including ion regulation.
