A good hypothesis to research would be: "toxic substances in the human environment"

Me ha encantado el hilo, muy didáctico

They adapted to life on land approximately 460 million years ago, evolving from green algae, and quickly began colonizing humid areas on a rocky, barren Earth. Since they lack vascular tissues like modern plants, they cannot grow large and rely on water for reproduction.

These primitive plants have unique characteristics that reflect their evolutionary origin. They adapted to life on land approximately 460 million years ago, evolving from green algae during the Ordovician period, and quickly began colonizing humid areas on a rocky, barren Earth.

Although its population is stable and classified as "Least Concern," it faces threats such as wetland degradation and the impact of intensive agriculture. Protecting these habitats is essential for its conservation and for maintaining the biodiversity they harbor.

In Spain, it is common in coastal and inland wetlands, such as Doñana, the Ebro Delta, or La Mancha Húmeda, but can also be observed in rivers and reservoirs in the central peninsula, like the Alberche.

Additionally, their black and white plumage is not only elegant but also helps them blend into open areas and reflect sunlight. This wader plays a crucial ecological role in wetlands, controlling populations of aquatic invertebrates and acting as an indicator of the health of these ecosystems.

These wading birds are a fascinating example of evolutionary adaptation: their long, red legs allow them to wade with ease, while their fine, straight beak is designed to catch insects, mollusks, and small crustaceans.

As seed dispersers, cranes contribute to the regeneration of holm oak forests and the ecological balance of the dehesas However, agricultural intensification and habitat loss threaten this ancient bond between birds and landscape Protecting the dehesas means protecting their history and their future

Here, they feed primarily on acorns but also on roots, insects, and small invertebrates, taking advantage of the rich biodiversity of the ecosystem. Although they breed in the wet boreal forests and northern taigas, the dehesas are their temporary home.
