Astrocytes: Orchestrators of brain gas exchange and oxygen homeostasis

open access: yesThe Journal of Physiology, Volume 604, Issue 4, Page 1682-1694, 15 February 2026.
Abstract figure legend Oxygen and carbon dioxide enter the body via breathing; in the brain astrocytes play a key role balancing oxygen delivery with carbon dioxide removal. Abstract If we consider neurons like muscles during exercise, the demand for oxygen (O2) and carbon dioxide (CO2) elimination is constantly changing.

Morphological traits and environmental preferences of the Blunt‐headed tree snake Imantodes cenchoa: the effects of sex and ontogeny

open access: yesJournal of Zoology, Volume 328, Issue 1, Page 41-51, January 2026.
Understanding how animals interact with their environment across life stages is key for conservation. In our long‐term study of the Blunt‐headed tree snake (Imantodes cenchoa) in the tropical rainforest of Los Tuxtlas, Mexico, we tracked over 240 individuals and found age‐related differences in environmental preferences.

Divergent Paths, Convergent Heads: Morphological Adaptation of Head Shape to Habitat Use and Diet in Snakes

open access: yesJournal of Morphology, Volume 286, Issue 11, November 2025.
Snake head shape is weakly constrained by phylogeny but strongly influenced by ecology. Significant convergence was detected in fossorial and aquatic snakes, while diet mainly drove morphological variation without convergence. ABSTRACT Morphological convergence—where distantly related species evolve similar traits in response to shared ecological ...

Generation of Anti-Boa Immunoglobulin Antibodies for Serodiagnostic Applications, and Their Use to Detect Anti-Reptarenavirus Antibodies in Boa Constrictor. [PDF]

open access: yesPLoS ONE, 2016
Immunoglobulins (Igs), the key effectors of the adaptive immune system, mediate the specific recognition of foreign structures, i.e. antigens. In mammals, IgM production commonly precedes the production of IgG in the response to an infection.
