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

Journal 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.

Betweenness centrality as neurophysiological marker of DMN functional connectivity in asymptomatic carriers of PSEN1 E280A for ADAD

Alzheimer's &Dementia, Volume 21, Issue S2, December 2025.
Abstract Background Graph metrics have been used to evaluate functional connectivity in Alzheimer's disease (AD). It has been found that nodal and global graph metrics are altered in subjects with AD and MCI compared to controls. In subjects with mutations associated with autosomal dominant Alzheimer's disease (ADAD), these metrics may vary depending ...

Periodic and Aperiodic EEG Parameters During Transitions from Wakefulness to Light Sleep: Preliminary Results on Patients with Mild Cognitive Impairment Due to Alzheimer's Disease vs. Healthy Elderly

Alzheimer's &Dementia, Volume 21, Issue S2, December 2025.
Abstract Background The periodic (e.g., EEG alpha power density) and aperiodic (offset and slope of EEG power density) components of resting‐state EEG rhythms reflect different aspects of global neural dynamics and have been linked to excitatory/inhibitory balance.

Ecosystem services provided by spiders

Biological Reviews, Volume 100, Issue 6, Page 2217-2236, December 2025.
ABSTRACT Spiders, ubiquitous and abundant predators in terrestrial ecosystems, often are the subjects of an unjust negative perception. However, these remarkable creatures stand as unsung heroes within our ecosystems, contributing a multitude of ecosystem services critical to human well‐being.

Learning to avoid: The long‐term effects of adolescent welfare participation on voting habits in adulthood

Policy Studies Journal, Volume 53, Issue 4, Page 1065-1087, November 2025.
Abstract Welfare participation is associated with lower turnout among adults. For many citizens, however, their first experiences with welfare occur during a critical time of political development in adolescence. Does growing up on welfare lower turnout in young adulthood?

Psychometric Properties of Eating Behaviour Instruments for Older Adults: A Systematic Review

Journal of Human Nutrition and Dietetics, Volume 38, Issue 5, October 2025.
ABSTRACT Introduction Although eating behaviour in children, adolescents and adults has been linked to changes in body mass, eating disorders and non‐communicable diseases, there is still uncertainty about how this behaviour has been measured in populations aged 60 and over, who are often exposed to age‐related physiological and cognitive changes ...

High‐Phenolic Cocoa Enhances Drug‐Induced Reinstatement of Cocaine‐Conditioned Place Preference Independently of Increasing Adult Hippocampal Neurogenesis

Food Science &Nutrition, Volume 13, Issue 9, September 2025.
High‐phenolic cocoa consumption enhanced cocaine‐induced reinstatement in a conditioned place preference paradigm. While cocoa promoted adult hippocampal neurogenesis, this effect did not mediate drug‐seeking behavior, suggesting a complex interaction between cocoa and cocaine on the reward system ABSTRACT Cocaine is a powerful psychostimulant that ...

Cuon Versus Canis: A Comparative Guide to the Morphological Distinction of Postcranial Bones and Its Archaeo‐Paleontological Implications

International Journal of Osteoarchaeology, Volume 35, Issue 5, Page 263-283, September/October 2025.
ABSTRACT The genera Cuon and Canis are part of the carnivore guild during the late Middle and Late Pleistocene in Europe. However, most identifications in archaeo‐palaeontological contexts are made on cranial and dental elements as these are taxonomically the most diagnostic anatomical regions.

Allometric Constraint Predominates Over the Acoustic Adaptation Hypothesis in a Radiation of Neotropical Treefrogs

Integrative Zoology, Volume 20, Issue 4, Page 763-773, July 2025.
Male frogs emit calls to attract mates and deter conspecific rivals. The evolution of these calls is thought to be linked to anatomical constraints and the acoustic characteristics of their surroundings. We tested these two factors in a radiation of 112 species of Neotropical treefrogs and found that body size and calling site affect peak frequency but
