Radiographic Assessment of Bone Maturation: A Tool to Estimate Sexual Maturity in Common Dolphins (Delphinus delphis)?

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Accurate inference of sexual maturity is fundamental to interpreting marine mammal life histories and population structure. Using Bayesian logistic regression models with a hierarchical ordinal (HOF‐style) parameterisation and canonical analysis of principal coordinates (CAP), we evaluate skeletal metrics in the pectoral flippers of common ...

Stable Isotope Analysis (δ13C and δ15N) of Baleen Plates Reveals Feeding Patterns in Stranded Humpback Whales (Megaptera novaeangliae) Along the Brazilian Coast

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Humpback whales (Megaptera novaeangliae) from breeding stock A migrate annually between Antarctic feeding grounds (~65° S) and Brazilian breeding areas (~17° S). Traditionally considered to fast during migration, recent feeding observations and increased strandings along southeastern Brazil (~23° S) raise questions about possible shifts in ...

An Evaluation of Mortality Rates and Their Determinants in a Cohort of Former Asbestos Miners in South Africa

open access: yesAmerican Journal of Industrial Medicine, Volume 69, Issue 6, Page 446-460, June 2026.
ABSTRACT Background A causal association between occupational asbestos exposure and lung disease, including pneumoconiosis and mesothelioma, is well established. Elevated mortality among former asbestos miners is expected. However, large‐scale South African studies examining all‐cause mortality in this population are lacking.

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Perinatal mortality in eastern Africa: A systematic review and meta‐analysis

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 173, Issue 3, Page 1207-1222, June 2026.
Abstract Background Every day, over 5000 stillbirths and more than 6000 newborn deaths are estimated to occur worldwide, the majority in sub‐Saharan Africa and South Asia. Estimates, however, rely on data that might underestimate these deaths. Further, outside major categories such as preterm birth, infection, and complications at delivery, little is ...

Knowledge, attitudes, and practices of abattoir workers about Taenia solium cysticercosis in the Eastern Cape Province, South Africa

open access: yesNatural Sciences Education, Volume 55, Issue 1, June 2026.
Abstract The tapeworm, Taenia solium, is the cause of cysticercosis, a neglected zoonotic disease that poses a significant global threat to animal and public health. Data were collected between May and June 2024 using a structured, interviewer‐administered questionnaire (n = 152) comprising demographic items and sections on knowledge, attitudes, and ...

An inquiry‐based activity to teach about insects of medico‐legal importance: Lessons from Redi's landmark experiment

open access: yesNatural Sciences Education, Volume 55, Issue 1, June 2026.
Abstract In this article, we describe an inquiry‐based teaching activity developed in a public high school in Brazil. The objectives were to (a) develop an experimental activity grounded on the students’ autonomy for formulating and testing hypotheses, (b) address Biology topics from a historical and multidisciplinary perspective, (c) stimulate skills ...

Structural analysis of Cu/Zn‐superoxide dismutase linked to neurodegenerative disease by antibody‐guided cryo‐EM

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Accumulation of misfolded proteins is a hallmark of many neurodegenerative diseases. To characterize such misfolded species in vivo, conformation‐specific antibodies are widely used; however, limited knowledge of antibody–epitope interactions often hampers mechanistic insight.
