Roteiro de aula prática sobre cinética enzimática com fosfatase de levedura e de batata.

Diferentes tipos de muros limitam as cidades, podem ser reais e invisíveis, físicos, naturais, sociais, culturais, políticos e econômicos. Dentro desta temática, apresenta-se uma proposta pedagógica que trabalha os muros no mundo, na cidade de Campinas/SP e na bacia do ribeirão Anhumas. A atividade teve seu princípio de elaboração pelo grupo de pesquisa de professores Linguagens e Representações (professores da E.E. Ana Rita Godinho Pousa), no projeto colaborativo universidade-escola Ribeirão Anhumas na Escola,  com um maior foco em conteúdos de Geografia e Português. Apesar da especificidade local do desenvolvimento do trabalho, a ideia básica poderá servir de auxílio à outros professores q...

A ilustração destaca interações comuns no ambiente urbano, oferecendo uma compreensão mais profunda das relações ecológicas. Ela retrata parasitismo, hemiparasitismo e epifitismo em um cenário típico das cidades, frequentemente ignorado por olhares menos atentos.

O presente estudo teve como objetivo determinar as alternativas viáveis para a implantação de sistemas de captação e aproveitamento de água de chuva no município de Joinville-SC. Trata-se de um estudo de percepção ambiental direcionado para o aproveitamento de água de chuva em Joinville e região, com uma amostra composta por atores sociais representativos dos diversos segmentos da sociedade (órgãos governamentais e não governamentais, instituições de ensino, entidades ambientalistas, secretarias regionais, associações de moradores e iniciativa privada). Os dados para a realização do estudo foram coletados através de questionários entregues pessoalmente nas instituições e, em alguns casos, en...

O meio rural não é mais um espaço onde são desenvolvidas atividades exclusivamente agrícolas, já que, tem passado por intensas mudanças, que induzem a pluriatividade, fazendo com que o espaço seja tido como um continuum da zona urbana. Estas mudanças que assemelham o rural do urbano trazem, a reboque desta reestruturação, mazelas há muito discutidas e pouco solucionadas, das “cidades”, como uso e ocupação do solo de maneira desregrada, ausência de saneamento básico, entre outras. A respeito do saneamento, o Gerenciamento Integrado de Resíduo Sólido ainda é uma realidade bem distante, para as comunidades rurais, mesmo para aquelas juntas às zonas urbanas. Desta forma, o objetivo deste trabalh...

It may have up to four broods a year, eac...

37cm It is a unique bird that can only be confused with other Potoos, from which it differs by being mostly gray. Not like any other bird, the Potoo is one of the best camouflaged birds on earth. It spends the whole day quietly perched on a carefully chosen branch in a way it blends with the substrate as the bird seems to be part of the tree. The large orange eyes, which could be a flaw for the camouflage are wisely covered by eyelids with a tiny fold in the middle, from which the bird can see the surroundings as the pupil is exposed while the orange iris is hidden. In the night the bird leaves its perch flying as a falcon in hunt for flying insects that it catches with its huge mouth...

24cm In urban areas there is only one other species of owl about the same size of the Screech Owl, that is the Burrowing Owl ( Athene cunicularia ), but while the Burrowing Owl is a diurnal species which lives mostly in open areas and spends most of the time on the ground, the Screech Owl lives on trees and has a pair of ``ears´´. The song reminds that of the Rococo Toad ( Bufo ictericus ). The Screech Owl feeds mainly on large insects but may also take mice, frogs and lizards. The nest is built in tree holes or in artificial boxes.

13,5cm The most distinguishing features of this species are the yellowish-orange head and the grayish-green body. This shades of color may vary depending on the subspecies, given that this bird is distributed thoughout the tropical region South to the Amazon river and East to the Andes. There is also a curiously isolated population in the Orinoco river basin. It lives in secondary forest, forest edges and even in cities with plenty of trees. Spends most of its time in the canopy, rarely coming to the ground. This bird moves in a very typical way, climbing the branches in a fast zig-zag, up to the tip and then letting itself fall onto the base of the next branch. It feeds mainly on s...

18cm Unlike the Red-crested Cardinal ( Paroaria coronata ) the Red-cowled Cardinal does not have a crest and the absence of black patches on the head and throat distinguishes this from the other Brazilian cardinals. This bird is endemic to the Brazilian Northeastern semi-arid region called ``Caatinga´´ where it is undoubtedly one of the most beautiful songbirds. Its beaty often costs its freedom as thousands of these birds are captured in the wild to be kept as cage birds. There is large illegal traffic of these birds throughout Brazil and even to other countries. Several specimens, and even established breeding populations have been reported considerably far from its original distrib...

60 cm. The tail is very long. The general color is reddish brown. The tail feathers are pale in their tips and in the inferior side. The head has a lighter coloration. The chest is gray. The young individuals have shorter tails. Distribution: From Mexico to Argentina. Habitat: Lives in the canopy of secondary forests, cerrado and urban areas with plenty of trees. Diet: Feeds on grasshoppers, bugs, caterpillars, spiders, etc. Also feeds on small vertebrates as treefrogs. Reproduction: In the breeding season the male sings restlessly 96 times a minute. Before mating gives the female a caterpillar. The nest looks like a frying pan made of loosely crossed branches and is placed in a tall...

22 cm. The beak is strong and black. The chest and the belly are bright yellow and the back is brown. The throat is white and the head black, with a white band above the eyes. Male and female are similar. Distribution: From Texas (U.S.A) to Patagonia. Habitat: It is one of the most generalist birds. Thrives in environments as different as rocky beaches and semi-arid landscapes. It is very common in cities. Does not penetrate dense vegetation, but may be found in forests near the riverbanks or in the borders. Diet: Also very generalist in the diet, consumes mainly insects, but also fruits, learns to catch small fish and tadpoles (as from the author’s tanks), hunts hatchlings and e...

19cm. The plumage is squamous. The general coloration is brown with some grayish parts. There is a white wingbar (when closed). When flying it shows a pattern of white in the wings and tail. Distribution: From Venezuela to Argentina. Habitat: Inhabits dry fields, cerrado, caatinga and parks in urban areas. Diet: Feeds on grains and fruits on the ground. Reproduction: It is monogamous. Builds a sparse nest in the shape of a cup, 1 or 2m from the ground, sometimes on the ground. The hatchlings (generally 2) are fed on pigeon’s milk that is rich in fat, proteins and lectines. They leave the nest after 15 days. The vocalization is very characteristic and in many places it is named a...

16cm. Identification: The male is practically unmistakably recognized for the fully barred body and a black crest in the head. The female is ferruginous and has a crest and is barred in the head. It is currently the only antshrike which lives in really urban and disturbed areas. It is worth reminding that this bird has only recently conquered the urban environment. In the early 80s the first records of this antshrike in large cities were so unexpected that they yielded notes in scientific papers. Like other antshrikes it lives in couples, leaping and flying from branch to branch, usually through the short trees’ canopy in search for the small arthropods it feeds on. In the breeding seas...
