1. Desenvolvimento sustentável na Rio+20: discursos, avanços, retrocessos e novas perspectivas
Depois de quatro décadas da Conferência de Estocolmo sobre o Meio Ambiente Humano, e decorridos apenas alguns meses da Rio+20, este artigo busca se aprofundar no caminho percorrido pela agenda global de desenvolvimento sustentável, a partir de Rio-92 até os desafios, em grande parte frustrados, da conferência recém concluída no Rio de Janeiro.

2. Quasi-experimentation in the study of culture: an analysis of Colapse by Jared Diamond / A quase-experimentação no estudo da cultura: análise da obra Colapso de Jared Diamond
A dificuldade em se estabelecer um programa de pesquisa sobre práticas culturais, cultura e evolução cultural na Análise do Comportamento deve-se em parte a questões conceituais (sobre as unidades de análise pertinentes e a complexidade inerente às culturas) e metodológicas (ausência de procedimentos experimentais adequados e timidez na exploração

3. Sobrevivência ou colapso? B. F. Skinner, J. M. Diamond e o destino das culturas
Um dos aspectos mais interessantes e polêmicos da obra de B. F. Skinner é sua interpretação sobre a evolução das culturas. De acordo com o autor, as conseqüências de práticas culturais retroagem sobre as culturas, no sentido de aumentar ou diminuir suas chances de sobrevivência. O livro "Colapso", do biólogo e geógrafo norte-americano Jared Diamo

4. Comparison of Faunal Equilibrium Turnover Rates on a Tropical Island and a Temperate Island
Rates of immigration and extinction of bird species on a tropical island, Karkar in the southwest Pacific Ocean, have been estimated from surveys made in 1914 and in 1969. Compared to a temperate-zone island of similar size and isolation (Santa Cruz off southern California), Karkar has a similar extinction rate, but a lower immigration rate expressed as a fr

5. Biogeographic Kinetics: Estimation of Relaxation Times for Avifaunas of Southwest Pacific Islands
When species diversity S on an island is displaced from the equilibrium value by injection or removal of species, S relaxes to equilibrium by an imbalance between immigration and extinction rates. Estimates of exponential relaxation times, tr, for avifaunas of New Guinea satellite islands are calculated from analysis of four “experiments of nature”: reco

6. AVIFAUNAL EQUILIBRIA AND SPECIES TURNOVER RATES ON THE CHANNEL ISLANDS OF CALIFORNIA
Insular species diversities, and their dependence on island size and isolation, have been postulated to represent a dynamic equilibrium between species immigration rates and species extinction rates. This interpretation has been tested by determining the land and freshwater birds breeding on the nine Channel Islands off southern California in 1968 and compar

7. Ecological Consequences of Island Colonization by Southwest Pacific Birds, I. Types of Niche Shifts
The land and fresh-water birds of the southwest Pacific islands derive mainly from New Guinea and offer a favorable situation for studying ecological consequences of island invasions. The reduction of competition on species-poor islands permits some colonizing species to expand their niches spatially, by occupying altitudinal bands, types of habitats, and/or

8. Species-distance relation for birds of the Solomon Archipelago, and the paradox of the great speciators
For scattered remote islands and for likely forms of immigration and extinction curves, the equilibrium theory of island biogeography leads to the prediction [unk]2 log S/[unk]A[unk]D > 0, where S is the number of species on an island, A island area, and D island distance from the colonization source. This prediction is confirmed for birds of the Solomon Arc

9. Animal art: Variation in bower decorating style among male bowerbirds Amblyornis inornatus
Courtship bowers of the bowerbird Amblyornis inornatus, the most elaborately decorated structures erected by an animal other than humans, vary geographically and individually. Bowers in the south Kumawa Mountains are tall towers of sticks glued together, resting on a circular mat of dead moss painted black, and decorated with dull objects such as snail shell

10. Ecological Consequences of Island Colonization by Southwest Pacific Birds, II. The Effect of Species Diversity on Total Population Density
Among southwest Pacific birds colonizing a species-poor island from a species-rich island, spatial expansion of the niche to include a wider range of altitudes, habitats, or vertical strata is often an immediate response, while changes in foraging techniques and diet usually occur more slowly and require genotypic change. Despite occupation of spatially broa

11. Species-area relation for birds of the Solomon Archipelago
Accurate values of number of breeding bird species have been obtained for 50 islands of the Solomon Archipelago. From information about species altitudinal distributions on each island, the values are apportioned into number of montane species (Smt) and of species present at sea-level (Slow). Slow increases linearly with the logarithm of island area A over a

12. Effect of species pool size on species occurrence frequencies: Musical chairs on islands
If species interactions affect species distributions, then species occurrence frequencies (νi), defined as the fraction of an archipelago's islands that species i inhabits, should vary with species pool size. A “natural experiment” approximating this test is provided by the Bismarck, Solomon, and New Hebrides archipelagoes, whose bird species pools decr
