1. Green turtle (Chelonia mydas) genetic diversity at Paranaguá Estuarine Complex feeding grounds in Brazil
Sea turtles are marine reptiles that undertake long migrations through their life, with limited information regarding juvenile stages. Feeding grounds (FGs), where they spend most of their lives, are composed by individuals from different natal origins, known as mixed stock populations. The aim of this study was to assess genetic composition, natal origins a

2. Taxonomic distinctness and conservation of a new high biodiversity subterranean area in Brazil
Subterranean environments, even though they do not possess a primary production (photosynthesis), may present high biodiversity, faunistic originality, endemism, phylogenetic isolations and unique ecological and/or evolution events, in addition to rare taxa. Studies investigating the biological diversity in Neotropical caves are relatively rare and recent, a

3. Community dynamics in a species-rich patch of old-growth forest in a global changing scenario
Ecological theory predicts that, in mature ecosystems, species richness, the number of individuals and the biomass of individuals will remain in a relatively stable state of equilibrium. The aim of this study was to test that theory. In 2001 and 2010, we conducted censuses of all trees with a circumference at breast height > 10 cm in a one-hectare plot in a

4. Macroecologia do zooplâncton continental: padrões latitudinais e componentes locais e regionais na determinação da diversidade global / Macroecology of continental zooplankton: latitudinal patterns and local and regional components in determining global diversity
One of the oldest and best known global biological patterns in ecology is the latitudinal gradient of richness, characterized by a decrease in the number of species from Equator toward the poles. Several hypotheses, even today, attempt to explain the variation that occurs in the pattern of diversity of many animal and plants. Despite the advances that have b

5. Macroecologia do zooplâncton continental: padrões latitudinais e componentes locais e regionais na determinação da diversidade global / Macroecology of continental zooplankton: latitudinal patterns and local and regional components in determining global diversity
Um dos padrões biológicos globais mais antigos e conhecidos em Ecologia é o do gradiente latitudinal de riqueza, caracterizado pela diminuição no número de espécies do Equador em direção aos polos. Várias hipóteses, ainda hoje, tentam explicar esta variação, que ocorre no padrão de diversidade de muitos organismos animais e vegetais. Apesar dos

6. The importance of beta diversity in local gall-inducing arthropod distribution
Many studies over the past twenty years have documented the richness of arthropod galling species around the world, and some have proposed hypotheses to explain local and global patterns of galling species richness. However, few studies have been directed toward understanding how the gall-inducing species are locally distributed. The aim of this study was to

7. Macroecologia do gênero Uca (Crustacea, Decapoda): padrões de diversidade, distribuição e respostas às mudanças climáticas globais / Macroecology of the genus Uca (Crustacea, Decapoda): patterns of diversity, distribution and responses to global climate change
O gênero Uca é composto atualmente por 97 espécies, distribuídas mundialmente, ocupando ambientes costeiros marinhos, principalmente da região tropical. Diversos campos de pesquisa têm desenvolvidos trabalhos usando o gênero Uca como modelo, entretanto, atualmente o conhecimento científico sobre esse grupo apresenta-se disperso, além disso, estudos

8. Biodiversidade e padrões de distribuição da anurofauna do Parque nacional das emas e entorno / Biodiversity and distribution patterns of frogs of the Emas National Park and surrounding
Composition and diversity of anuran amphibians in preserved and disturbed environments in the Cerrado of the State of Goiás, Mid-West Brazil. The Cerrado is the second largest biome of Brazil, with an approximate area of 2 million km, which represents about 23% of the total area of the country. Despite the high conversion of natural areas of the Cerrado in

9. Macroecology of the genus Uca (Crustacea, Decapoda): patterns of diversity, distribution and responses to global climate change / Macroecologia do gênero Uca (Crustacea, Decapoda): padrões de diversidade, distribuição e respostas às mudanças climáticas globais
Macroecology of the genus Uca (Crustacea, Decapoda): Patterns of diversity, distribution and responses to global change. The genus Uca, composed by 97 species, has a worldwide distribution on coastal marine regions, mainly in tropical environments. Many researches have used the genus Uca as a model of study, although the actual scientific knowledge about thi

10. Sucessão ecológica em parcelas orgânicas de madeira, macroalgas e em carcassas de baleia no mar profundo; e similaridade de espécies entre habitats redutores no talude continental da Califórnia (Pacífico Nordeste) / Whales, wood and kelp islands in the deep-sea: ecological succession and species overlap with other chemosynthetic habitats in the Californian continental slope (NE Pacific)
Sunken parcels of macroalgae, wood and whale carcasses provide important oases of organic enrichment at the deep-sea floor, but sediment community structure and succession around these habitat islands are poorly evaluated. We experimentally implanted parcels of kelp and wood falls nearby a 30-ton deep-sea whale-fall at 1670 m in the Santa Cruz Basin (SCr; NE

11. Ecoregion priorization for terrestrial vertebrate conservation / Priorização de ocorregiões para a conservação de vertebrados terrestres
I aimed to identify conservation priorities for terrestrial vertebrates across different spatial scales (from regional/continental to global), using ecoregions as geographic units. I have evaluated, in particular, (1) the congruence between overall richness and endemism patterns among terrestrial vertebrates that occur in Brazil, and the effectiveness of eac

12. Latin American cities: convergence or diversity in the contemporary process of the space production. / Cidades latinoamericanas: convergência ou diversidade no processo de produção contemporânea do espaço.
A pesquisa aborda a produção do espaço urbano das regiões metropolitanas de São Paulo, Buenos Aires e Cidade do México. Inicialmente examina-se a formação histórica dos seus padrões de urbanização, a partir das respectivas dinâmicas socioeconômicas, histórico-políticas e territoriais dominantes ao longo do século XX, e em seguida analisam-se
