Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

Oikos, EarlyView.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

The influence of sand extraction on fish assemblages in campinarana streams in Cruzeiro do Sul – AC, Brazil

Biotemas, 2019
Habitat destruction promoted by sand extraction from streambeds can cause the loss of some species and change the dynamics of fish assemblages. The present study investigated the effect of sand extraction on fish assemblages in campinarana streams in ...

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Recurrent and bilateral inverted sinonasal papilloma with intraorbital and intracranial extension. A case report

Iatreia, 2016
Inverted papilloma (IP) is a relatively rare neoplasm of the nasal cavity and paranasal sinuses. Although it is considered a benign tumor, its biological behavior is not so benign because of local aggressive growth, high recurrence rate, and risk of ...

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

DESENVOLVIMENTO DA CULTURA DO MILHO SOB EFEITOS DE DIFERENTES PROFUNDIDADES DE COMPACTAÇÃO DO SOLO

Revista de Agricultura Neotropical, 2016
A compactação do solo determina, de certa maneira, as relações entre ar, água e temperatura, e estas influenciam praticamente em todas as fases do desenvolvimento vegetal.
