Esquemas de principais tipos de flores, evidenciando características morfológicas que são o padrão geral observado nos principais grupos taxonômicos de angiospermas. Cores auxiliam na interpretação comparativa das peças florais em diferentes flores.

Podcast curto que explica sobre classificação biológica (o que é e como é feita), com ênfase em plantas com flores. Não há continuação em próximos episódios, o nome do Podcast é fictício.

Programa de áudio que aborda a vida e a atuação de Chico Mendes.

Edge effect: periphery areas of forest fragments are more suceptive to external impacts, leading to environment degradation from the outside towards the inside.

Esse infográfico aborda, resumidamente, as diversas fontes de evidências utilizadas para a construção de uma árvore filogenética. É apresentada uma filogenia simplificada dos principais grupos de angiospermas e tendências gerais do padrão morfológico de suas flores.

O infográfico e o ilustração retratam a biodiversidade e a sua preservação, no qual tem como objetivo defender a importância das natureza e a sua preservação. Admitindo que as ações do homem são devastadoras para as florestas.

Breve exemplo ilustrativo de polinização por dois insetos distintos, com o intuito de utilização como material complementar, não sendo suficiente para explicação do conceito por si só.

O podcast aborda a preservação da biodiversidade da Amazônia, no qual duas mulheres discorrem sobre o assunto.

Ilustração feita a partir de imagens e figuras a fim de demonstrar o passado do bioma Mata Atlântica, com sua riqueza de espécies e de cores, em comparação com seu presente e futuro, dado que grande parte do bioma já foi degradado.

Length: 9,5cm Identification: the back is bright green, the tail and part of the wings are dark blue. The throat and the chest is sapphire-blue. The belly is white and there is a white line splitting the chest. The two sexes look alike. It is one of the main pollinators of several plant species, including some introduced ones. It is territorialist and visit the flowering patches at predictable times. It explores even the lowest flowers. This hummingbird usually explores feeders where it fights against the bananaquits ( Coereba flaveola ) and the swallow-tailed hummingbird ( Eupetomena macroura ). The bow-shaped nest usually shelters two eggs.

Physical appearance: 11 cm. The upper parts are dark and the inferior parts yellow. There is a white bar in the supercilium. The females are smaller than the males. The immature individuals have grey belly and do not have the bar above the eye. Distribution: From Mexico to Chile. Habitat: Inhabits various environments provided there is plenty of trees and flowers. Diet: Feeds mainly on nectar. Also eats insects. Visits hummingbird feeders. Reproduction: Builds two kinds of nest. A breeding one that is compact with thick walls and a resting nest made of leaves, grass and spider webs. Lays two or three white eggs. Only the female incubates. The male helps feeding the brood with i...

Physical appearance: 26 cm. The upper parts are green, somewhat yellow, barred in black. The inferior parts are buffy or white, also barred. The tail and the top of the head are black. The male has a red spot below the eye while in the female this spot is black. Distribution: From Eastern Amazon to Uruguay and Argentina. Habitat: Forest borders, gallery and secondary forests, woods and parks in cities. Diet: Feeds on ants and insect larva, mainly beetles. Also eats fruits. Reproduction: After courtship the couple builds a nest inside an old tree, sometimes palm trees and others. The nest is generally downwards, avoiding the water when it rains. Two to four eggs are laid and the ...

62 cm in length, 143 cm of wingspan. The feathers are absent in the head and neck. The body is black, with white spots near the tip of the wings (seen only when flying). Distribution: From central U.S.A to central Argentina. Habitat: Virtually in any kind of landscape, preferably in open areas. Absent in large areas of dense vegetation. Diet: Mainly carrion. Does not hunt, but kills injured or young animals, such as turtle eggs and hatchlings, even newly born big mammals like calves. May eat fruits. The excellent eyesight helps finding carrion at long distances. Reproduction: The courtship consists of movements of the male jumping on the ground with the wings opened and then...

48cm Identification: the body is mostly cinnamon with dark streaks on the wings. It may be locally the commonest duck, especially in Southern Brazil wetlands, where its hunting is allowed provided the state’s quotas are respected. Regarding its habitat this species tends occur in open wetlands, surrounded by grasslands. Feeds mainly by grazing small grasses on the lake shores or underwater but also eats aquatic plants, aquatic insects and small fish. It may build the nest either in a tree hole or on the aquatic plants. The female lays from 8 to 14 eggs that are sat for about one month. The offspring start to fly within 55 days after hatching.

16cm Identification: the genus Elaenia is well known among the ornithologists for being one of the most difficult groups when it comes to species identification. Nevertheless Elaenia flavogaster is the easiest species to be identified, first for its yellow belly, second for the crest on the head (not always visible), third for the absence of white patches on the face and crest and last for its conspicuous behavior. It is more easily heard than seen and its song reminds the one of the kiskadee. It inhabits parks, backyards, coffee crops and secondary forest edges. The yellow bellied elaenia spends most of its time in the medium height trees and shrubs. Feeds mainly on insects and be...

19 cm. The Variegated Flycatcher is one of 3 widespread flycatchers that are streaked below. The Variegated is larger than the Piratic Flycatcher (Legatus leucophaius), has a longer bill, more rufous on the tail and whiter edging to its wing feathers. On the other hand, it is smaller than the Streaked Flycatcher (Myiodynastes maculatus) with darker upperparts and less well defined streaking below. Distribution: Throughout South America, mainly in the south. Habitat: Lives in forest borders and open areas provided there are tall trees in which it can perch. Diet: Flying insects, insects in the foliage and sometimes small fruits. Reproduction: The couple takes care of each other’s...

15cm Identification: it is one of the largest hummingbirds. It is easily identified by the forked tail, reminding a pair of scissors. Unmistakably Brazilian’s best known hummingbird, this magnificent animal is also one of the most belligerent ones. It fiercely defends its territory – usually consisting of a flowering patch – against other birds, especially the bananaquit ( Coereba flaveola ). It sucks sweet water from feeders even if these are place in the interior of the houses, fearlessly entering the rooms. Like other hummingbirds it feeds mostly on nectar but also on insects. The female lays 2 or 3 eggs in a small bow-shaped nest and feeds the nestlings mainly with arthropods.

35cm Identification: the head is dark with a bege band on the eyebrows and another one on the neck. The throat is white, but unlike Falco rufigularis this ribbon is not extended up to the back of the neck. The chest is light brown with black dots, unlike Falco deiroleucus which presents this region orange. The belly is dark with white spots and there is a red patch near the tail. The tail is dark with three white bars. It is one of Brazilian commonest falcons since it inhabits open landscapes, included those disturbed by men. Feeds on small rodents and birds, reptiles and large insects. Like other falcons these are monogamous birds with fixed breeding grounds. The nest is built o...

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...

21cm May be confused with the Piratic Flycatcher and the Variegated Flycatcher ( Empidonomus varius ), but is larger than both. It is a solitary and quiet species which sings mostly at twilight. This flycatcher spends most of the time perched in forest edges. Feeds mainly on flying insects, but also takes berries. The nest is usually built in a forked branch or in tree holes. The female builds the nest and incubates the eggs, which hatch within 16 – 17 days. The couple takes shifts to feed the nestlings which leave the nest within 18-21 days. Migrates to lower latitudes in the winter.
