He friend-zones her despite her clear affection for him.

He friend zones everyone who confesses a crush on him, even when he secretly likes them.

The researchers traveled to several demilitarized zones to study how biodiversity recovers in areas free from military activity.

Scientists studying climate change are increasingly concerned about melting ice sheets in frigid zones and the global consequences.

Marine biologists survey intertidal zones at dawn to observe feeding behaviors before the tide changes.

Deep-sea creatures migrate vertically each night to feed in the aphotic zones, returning to darker depths by dawn.

Conservationists mapped the zones of rarity across the island to prioritize habitats for protection.

During the experiment, the researchers mapped the foveal zones to study how attention affects fine-grained vision.

Photic zones support most marine photosynthesis, so nutrient cycles there drive entire coastal ecosystems.

The expedition avoided the lethal zones marked on the map, knowing that a single mistake could be fatal.
