Ecologia política: onde está a ecologia?

Desenvolvimento E Meio Ambiente, 2011
RESUMO Enquanto a ecologia política avançou, sua coerência como campo de estudo e suas contribuições intelectuais centrais permanecem tema de debates por vezes controversos.

Da Ecologia Geral à Ecologia Humana [PDF]

Forum Sociológico, 2007
Apesar da ancestralidade e perenidade das relações Homem-Ambiente o seu tratamento científico tardou, sendo preciso chegar-se ao início do século passado para que tal começasse a alterar-se.

Ecologia

Revista Eclesiástica Brasileira, 1992
Indiscutivelmente a Ecologia encontra-se entre as grandes questões da atualidade. Dados alarmantes apontam para a seriedade do problema. Consequentemente multiplicam-se congressos, simpósios, artigos e livros, em todos os níveis e para todos os gostos. Tudo isso está provocando uma consciência bastante generalizada das ameaças que pairam sobre todas as

Fine‐scale genetic structure of the cloud forest tree Ocotea psychotrioides revealed by genome‐wide SNP data

American Journal of Botany, EarlyView.
Abstract Premise Recent advances in genomic technologies now enable the reconstruction of evolutionary histories at fine spatial scales, illuminating the complex dynamics that shape biodiversity patterns in naturally discontinuous, archipelago‐like ecosystems such as cloud forests.

refloraR: An R package for efficiently retrieving and analyzing plant specimen data from the Herbário Virtual Reflora

Applications in Plant Sciences, EarlyView.
Abstract Premise Advances in the digitization of herbarium collections are enabling open access to specimen data for research and conservation. In Brazil, the Herbário Virtual Reflora (HVR) hosts over 4.8 million high‐resolution images of botanical specimens and their associated data from 86 national and international herbaria.

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

The lower deciduous dentition of protodidelphids (Mammalia, Marsupialia) from the Itaboraí Basin (lower Eocene), Brazil, and the validity of “Riolestes capricornicus” (Goin et al., 2009)

The Anatomical Record, EarlyView.
Abstract The Itaboraí Basin, Southeastern Brazil, preserved one of the most diverse mammalian faunas from the Paleogene, with Metatheria comprising more than 60% of its diversity. Among identified metatherian clades, it has been argued that Paucituberculata is represented by “Riolestes capricornicus”.

Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...
