Polarization devices play a key role in many optical technologies and applications. However, traditional polarization devices are often large and lack integration, and achieving polarization conversion typically requires combining multiple devices, which makes it challenging to realize integrated optical systems. Following the current trend of optical devices, we propose a method using polarization holographic exposure to prepare polarization conversion devices.

Human overexploitation contributed strongly to the loss of hundreds of bird species across Oceania, including nine giant, flightless birds called moa. The inevitability of anthropogenic moa extinctions in New Zealand has been fiercely debated. However, we can now rigorously evaluate their extinction drivers using spatially explicit demographic models capturing species-specific interactions between moa, natural climates and landscapes, and human colonists.

The four honeybee species native to Cambodia-, , , -play a vital role in ecosystem health and agricultural productivity through their pollination activities. Beekeeping in Cambodia has primarily developed around the introduced species . However, it remains underdeveloped compared to neighboring countries, with wild honey collection continuing to play a significant role.

The abiotic stresses to which plants are exposed, especially in times of climate change, can result in the disruption of natural plant physiological processes. Sudden atmospheric phenomena may increase the risk of failure in protecting rare and extinction-threatened plant species by translocation. This study aimed to determine the effect of extreme ambient temperatures on the condition and physiological response of plantlets used for their reintroduction into the natural habitat.
