Assessing predictive accuracy of species abundance models in dynamic systems
Abstract Cascading human pressures and environmental change are affecting the natural dynamics of animal populations. Forecasting population abundances from time‐series data provides an important avenue for testing competing ecological theories and for supporting conservation planning and sustainable use, yet changing system dynamics may lead to ...

Abstract Background and objectives Epididymal transit renders key competence to mammalian spermatozoa for fertilizing eggs. Generally, the two paralogs of glycogen synthase kinase 3, GSK3α and GSK3β, functionally overlap except in testis and sperm. We showed that GSK3α is essential for epididymal sperm maturation and fertilization.

Default mode network (DMN) consists, in part, of the frontal (FC), precuneus (PreC), and posterior cingulate cortex (PCC), which plays a critical role in episodic memory and retrieval of autobiographical memories, displays spatiotemporal differences in the onset of amyloid and hypometabolism that reflects tau neurodegeneration and loss of connectivity ...

Algal‐farming damselfish in high‐quality habitats with more neighbours and smaller territories did not differ in their defence costs to those in poorer habitats with larger territories and fewer neighbours. While overall intrusion and attack frequencies were similar between these two habitat areas, territory holders interacted differently with ...

Long‐Term Mobility of a Harvested, Rocky‐Reef Gastropod
ABSTRACT Stocks of Turbo militaris (Turbinidae) are under increasing harvesting pressure, but management is currently hampered by data deficiency. Management decisions for rocky‐reef gastropod fisheries should consider long‐term species mobility, yet this is often poorly understood. Therefore, mark‐recapture was used to evaluate annual displacement and
