Infográfico que contém de forma sucinta e atrativa estratégias que os organismos usam para evitar predadores, além da fuga.

Nesse episódio, a apresentadora Mariana Conda discute com o ecólogo Léo Marinho (fictício) estratégias que os organismos possuem para evitar e se proteger dos predadores, dando destaque para um artigo publicado em 2015 sobre o tema. Artigo citado: https://doi.org/10.1371/journal.pone.0120351 Vozes: Mariana Conda - Gabriela Prada Léo Marinho - Pedro Forti

Nesse episódio falamos a respeito da importância da preservação dos tubarões, citamos fontes para maior conhecimento dos animais e incentivamos o público a não consumir e nem pescar tubarões.

Length: 20cm Identification: nightjars are always very difficult to identify as they are nocturnal birds, rarely seen during the day due to their camouflage. On the other hand there are few species inhabitting urban areas and among these the little nightjar is usually the smallest and with the lightest color pattern. Distribution: it is distributed through all the South American countries east to the Andes. Habitat: occurs in a wide range of ecosystems, but is specially common in forest edges surrounded by crops and wetlands. This nightjar spends the whole day quiet and very well camouflaged on the ground and thus is rarely seen at daylight. It only flies during the day ...

10,5 cm. The beak and a mask around the eye are bright red. The body is light brown, finely streaked. There may be a red region in the belly. As in other species of cage birds there is great color variation. Distribution: Originally in Africa but currently found in many places around the world. In Brazil it may be found in most of the country except from the Amazon region (where it may be found in the suburbs of big cities). Habitat: Open landscapes, fields, crops, gardens and parks. Diet: Seeds and occasionally insects. Reproduction: The nest is built by the couple in shrubs. Its walls are thick and made of grass, feathers and cotton. The entrance is hidden. Sometimes a false n...

19 cm. The body is brown, darker in the back and ferruginous in the tail. The ventral part is light brown. Distribution: Northeast, Mideast to South of Brazil, also in Argentina, Paraguay, Uruguay and Bolivia. Has been spreading its distribution along with deforestation. Habitat: Open landscapes, fields, cerrado, lawns and gardens. Diet: Mainly arthropods, sometimes seeds. Reproduction: The couple builds the nest with mud, manure and straw that they carry with their beaks and model with their feet. The nest is usually built on tall trees. Each year a new nest is built, sometimes over the previous ones (up to 11 nests one above the other). The nest has two divisions and the eggs...

30cm Members of the Caprimulgidae family are very difficult to tell apart. The best clues to recognize the Pauraque are its very typical song and the fact that it is one of the few nighthawks to get so close to urban areas. The Pauraque spends the whole day quietly sat on the ground, so well camouflaged that it is almost impossible to see. It remains quiet when approached, but when you are too close the bird flies in a fast zig-zag, and lands few meters away. It is curious to notice that even landing close it is difficult to see. The eggs are laid directly on the ground and have an earthy color. The Pauraque can be easily seen on dirt tracks at night, when its eyes reflect the carsâ...

25 cm. The supercilium is white. The plumage usually shows traces of earth. The male is slightly larger than the female and the belly is lighter. Distribution: From Canada to Tierra del Fuego. Habitat: Open fields, grasslands and suburbs, sometimes in soccer fields. Diet: Feeds mainly on beetles, but also other arthropods. Also consumes small vertebrates. Reproduction: The nest is a deep hole in the ground (1,5 to 3m of depth). Although it is able of digging its own hole it generally uses the ones dug by other animals as the armadillos. The couple lines the nest with grass and dry manure. The female lays up to four eggs. The female incubates and the male takes care of the brood. ...

35 cm. The eyes and the legs are red. Has a topknot in the head and a spur in each wing. There is a black band in the throat that begins in the forehead and ends in the chest. The belly is white, the back and the wings are grayish brown and there are green and ferruginous spots in the wings. Distribution: From Panama to Tierra del Fuego. Habitat: Grasslands, open fields, lawns and sometimes soccer fields. Diet: Insects that it catches on the ground. Sometimes catches small fish in shallow wetlands. Reproduction: The nest is made of dry leaves (mainly grass) and placed in a small depression on the ground. Each male may have two females laying their eggs in the same nest. The femal...

O podcast em questão aborda o mimetismo em borboletas, que consiste em uma estratégia evolutiva que muitas espécies utilizam para se proteger e garantir sua sobrevivência e reprodução. Ao longo do podcast descobriremos o que define o mimetismo, quais são seus tipos, qual a diferença entre mimetismo e camuflagem e exploraremos os padrões de cores, de formas e de comportamentos que as borboletas exibem para enganar seus predadores.
