Koedoe: African Protected Area Conservation and Science – A retrospection: 1958 to 2018

Koedoe: African Protected Area Conservation and Science, 2019
In 2018, Koedoe celebrated an unbroken publication record of 60 years. From uncertain beginnings in 1958, it is now a mature and important internationally recognised scientific journal focussing on conservation and science in national parks in South ...

Assessing critical population thresholds under periodic disturbances

Ecosphere, 2023
Population responses to repeated environmental or anthropogenic disturbances depend on complicated interactions between the disturbance regime, population structure, and differential stage susceptibility.

High-Resolution Multiband 3D Imaging of Egyptian Papyri: Integrating Ultra-Close-Range Photogrammetry and Reflectance Transformation Imaging for Enhanced Documentation

Sensors
Egyptian papyri are commonly documented using high-resolution two-dimensional imaging, which enhances legibility but does not adequately capture the micrometric surface morphology required for material and conservation studies. To address this limitation,

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Intersecting Social Science and Conservation

Frontiers in Marine Science, 2021
There is a growing consensus that current conservation strategies are unable to cope with the acceleration of human-caused environmental degradation. The philosophies that underpin and shape traditional conservation initiatives have begun to shift toward

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

The sacred deer conflict of management after a 1000‐year history: Hunting in the name of conservation or loss of their genetic identity

Conservation Science and Practice
Human–wildlife conflict involves diverse stakeholders with conflicting values. Resolving such conflicts necessitates the development of management plans rooted in scientific knowledge and establishing of social consensus.
