Última Naturalness and Place in River Rehabilitation Ecology and Society Fryirs, Kirstie; Macquarie University; kirstie.fryirs@els.mq.edu.au; Brierley, Gary J; University of Auckland; g.brierley@auckland.ac.nz. An authentic approach to river rehabilitation emphasizes concerns for the natural values of a given place. As landscape considerations fashion the physical template upon which biotic associations take place, various geomorphic issues must be addressed in framing rehabilitation activities that strive to improve river health. An open-ended approach to river classification promotes applications that appreciate the values of a given river, rather than pigeonholing reality. As the geomorphic structure of some rivers is naturally simple, promoting heterogeneity as a basis for management may not always be appropriate. Efforts to protect unique attributes of river systems must be balanced with procedures that look after common features. Concerns for ecosystem...

Ano: 2009 Relationship between germination and bell pepper seed structure assessed by the X-ray test Scientia Agricola Gagliardi,Bruna; Marcos-Filho,Julio. Alternative use of the X-ray test to evaluate seed quality has become increasingly diverse. This study was performed primarily to establish experimental procedures and verify the effectiveness of the X-ray test to detect damage or abnormalities in bell pepper (Capsicum annuum) seed structure associated with germination. Five seed lots each of hybrids Reinger and Sentinel were used. Two hundred seeds per lot were exposed to durations and intensities of X-radiation and visually classified into four categories according to the proportion between the area occupied by the embryo and endosperm in relation to the total cavity area in the internal seed structure, e.g. 0, < 50%, 50-75% and 100%. The last category was subdivided into two others based on the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Seed analysis; Embryo morphology; Physical integrity.
