Fragmentation in Araucaria araucana forests in Chile: quantification and correlation with structural variables [PDF]

, 2016
Landscape fragmentation is one of the main threats to South American temperate forests due to population growth, conversion of native forests to plantations of exotic species and non-sustainable timber harvesting.

Fragmentation of Araucaria Forests in the Chapecó Ecological Corridor, Santa Catarina [PDF]

Biotemas, 2011
In Brazil, only 2% of the Araucaria forest remains, and less than 1% of this forest is protected (as conservation units). In Santa Catarina, the Chapecó River sub-basin was evaluated for the creation of a state ecological corridor. Studies were developed

Chuva de sementes de espécies lenhosas florestais em mosaicos de floresta com Araucária e campos no Sul do Brasil Seed rain of woody species in mosaics of Araucaria forest and grasslands in Southern Brazil

Acta Botânica Brasílica, 2011
Mecanismos de dispersão de diásporos e recrutamento de plântulas evitam a competição intra-específica e possibilitam a colonização de novos ambientes. Em áreas de transição entre florestas e vegetação campestre esses processos não são aleatórios, e sim ...

Evaluation of food safety in the handling of home enteral nutrition based on a new contamination risk classification: A cross‐sectional study

Nutrition in Clinical Practice, EarlyView.
Abstract Background Home enteral nutrition (HEN) offers clinical benefits and is increasingly used, although handling‐related health risks remain unclear. This study assessed food safety in HEN using a new contamination risk classification. Methods First, the inter‐rater reliability of the Food Safety for Handling HEN checklist was analyzed in 25 ...
