Processo da crise da biodiversidade e da perda dos habitats naturais. Foto com biodiversidade, foto com desmatamento e queimadas, foto com local urbanizado

nesse epsódio tratamos de temas como a biodiversidade, sua importância e os impactos de sua destruição, com convidados especialistas no assunto (fictícios).

trata-se de um folheto contendo conteúdo didático que aborda as questões da crise da biodiversidade e a perda de habitas naturais.

15 cm. The body is white with a band around the eye, the wing and the tail black. Distribution: From Northeastern Brazil to São Paulo. It is currently spreading its distribution southwards. Habitat: Lives in riverbanks, muddy places near lakes and ponds. Diet: Feeds mainly on arthropods, sometimes small fruits. Reproduction: The male exhibits himself standing on the body and opening the tail and the wings. The nest is spherical with a lateral entrance. It is built on small trees above the water. The white eggs are incubated by the female. Natural history: Runs on the aquatic plants, catching insects among them. Attacks other birds that enter its territory. Some people and eve...

11,5cm. Identification: there is no other Brazilian species like this bird, at least not in urban and disturbed areas. Formerly all the house wren populations ranging from Canada to Chile were considered as a single species, but after several studies the populations south to Mexico were renamed as the Tropical House Wren (Troglodytes musculus ). This hyperactive bird hops non-stop on the ground in search for the small invertebrates it feeds on, reminding a mouse (musculus = mouse ). It only perches to rest or to sing. Its song is very complex and melodic, like other well known members of the Troglodytidae family. It is famous for the breeding behavior, as this bird may nest in the mos...

40cm. Identification: its most typical characteristic is the long forked tail. The only species it can be confused with is the Fork-tailed Flycatcher ( Tyrannus savana ), which has the lower parts in white, the head in black and the long tail feathers are broader. Very little is known about this species although it is distributed throughout central and southern Brazil even in disturbed habitats. It is usually found alone or in pairs, near wetlands. This bird spends most of its time perched. Feeds mainly on flying insects that it hunts in short flights from the perch It seems to be seasonal, but the migration routes are mostly unknown.

A forma do bico das aves é adaptada para a alimentação específica de cada espécie, permitindo a sobrevivência em seus habitats. Bicos longos e finos alcançam o néctar das flores, enquanto bicos curtos e robustos quebram sementes. Assim, o habitat influencia a diversidade de bicos, facilitando a captura de alimentos.

O presente material discute de forma contextualizada os impactos das ações humanas sobre a vida selvagem no Brasil, destacando os efeitos do desmatamento, da poluição, da fragmentação de habitats e de outras formas de degradação ambiental. A partir de uma perspectiva biológica e ecológica, são analisadas as consequências dessas atividades para a biodiversidade e para o equilíbrio dos ecossistemas. O conteúdo também propõe reflexões sobre práticas sustentáveis e ações de conservação, visando promover a conscientização ambiental e o engajamento dos estudantes na proteção das espécies nativas e dos ambientes naturais.
