Threats to and management of Natura 2000 protected areas relative to agricultural practices
Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

ABSTRACT The synthesis and accumulation of active ingredients in medicinal plants are distributed in specific organs, tissues, and cell types, which are important for the exploitation of medicinal plants. However, the fine distribution of active ingredients is difficult to know. Here, the system of mass spectrometry imaging (MSI) integrated with single‐

Abstract Introduction Temporary ponds in the Mediterranean climate have a high conservation value, but many have been severely destroyed or degraded. Pond restoration and new pond creation have been engaged widely. Evaluations of the success of such operations are generally carried out over 10–15 years and show divergent results over this timeframe. In

Precise modulation of Fe–N4 site distances constructs spin‐regulated Fe–N4 twins, triggering a volcano‐type Fenton‐like activity and promoting oriented singlet oxygen generation. The twin‐site catalyst enables highly selective and efficient hospital wastewater purification with simultaneous pharmaceutical degradation and disinfection under low ...

Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.

A computational model for retinal haemodynamics under gravitational and postural variations
Abstract figure legend The haemodynamic impact of gravitational and postural changes on the retina, and its relevance to spaceflight associated neuro‐ocular syndrome (SANS), remains incompletely characterized. This study assesses retinal haemodynamics from upright to head‐down tilt using a lumped‐parameter model that dynamically couples intraocular ...
