“…Ao contrário, as plantas C mantiveram um crescimento contínuo em altura e apresentaram um maior investimento em ramos laterais (figura 1C). Um maior investimento no crescimento em altura em ambientes sombreados é uma resposta bastante comum, relatada em vários trabalhos (Cancian & Cordeiro 1998, Poorter 1999, Ferrer & Dillenburg 2000, Jurado et al 2006, inclusive para a espécie em estudo (Inoue & Torres 1980). No entanto, verifica-se que a vantagem de altura das plantas sombreadas sobre as controle é transitória.…”

-(Morphological and physiological adjustments in young plants of Araucaria angustifolia (Bertol.) Kuntze in response to shading). This study evaluated the ability of plants of Araucaria angustifolia in adjusting some aspects of their morphology and physiology to different light conditions. Plants were submitted to full irradiance and shaded (90% reduction) conditions. During the course of a greenhouse experiment, four harvests were made (31, 49, 75 and 158 days after planting) and growth measurements of the shoot and roots were taken. A reduction in dry mass accumulation was observed in the shaded plants. These plants also had an initial enhancement of height growth, accumulated more chlorophyll, and, by the end of the experiment, had branched less and attained a greater leaf area ratio than the control plants. These morphological and physiological changes, which exhibited a temporally discontinuous expression, were interpreted as adjustments towards a more efficient light absorption and resource conservation under shading, which may contribute to the reported hade tolerance of the species.

Este trabalho avaliou a capacidade de plantas de Araucaria angustifolia em ajustar alguns aspectos de sua morfologia e fisiologia a diferentes condições de luz. As plantas foram submetidas a irradiação plena e sombreamento (redução de 90%). Ao longo do experimento, conduzido em casa de vegetação, foram efetuadas quatro avaliações (31, 49, 75 e 158 dias após o plantio) de crescimento na parte aérea e no sistema radicular. Uma redução no acúmulo de massa seca foi verificada nas plantas sombreadas. Estas também exibiram maior crescimento inicial em altura, acumularam mais clorofila e, ao final do experimento, haviam ramificado menos e atingido maior razão de área foliar, quando comparadas às controles. Estas alterações morfológicas e fisiológicas, cujas expressões foram temporalmente descontínuas, foram interpretadas como ajustes para uma absorção mais eficiente de luz e de economia de recursos sob condições de sombreamento, devendo contribuir para a relatada tolerância ao sombreamento da espécie. Palavras-chave: luz, pinheiro brasileiro, tolerância à sombra IntroduçãoAraucaria angustifolia (Bertol.) Kuntze (Araucariaceae), também conhecida como pinheiro brasileiro ou pinheiro-do-paraná, é uma das essências florestais mais importantes no sul do Brasil. A espécie destaca-se pela alta qualidade de sua madeira, fonte de alimento para a fauna e para o homem, como também pela exuberante beleza paisagística na região onde ocorre (Reitz & Klein 1966).A exploração irracional e descontrolada de sua valiosa madeira nos últimos 40 anos reduziu a área de ocupação da espécie, de cerca de 200.000 km 2 para aproximadamente 6.000 km 2 . Essências exóticas (em sua maioria dos gêneros Pinus e Eucalyptus) têm sido selecionadas para projetos de reflorestame...

“…Because abundance of seedlings in arid and semi-arid environments is generally low (García and Jurado, 2003;Flores et al, 2004;Holzapfel et al, 2006;Jurado et al, 2006), the effect of elevation on survival of seedlings has been studied using sown seeds in pots (García et al, 2007) and in local soils at different elevations (García, 2006). In our study, we investigated abundance of seedlings of all naturally occurring species to determine current information on abundance of seedlings, which will form the basis for comparisons in future studies.…”

Citation: Gaertner M, Fisher JL, Sharma GP, Esler KJ (2012) Insights into invasion and restoration ecology: Time to collaborate towards a holistic approach to tackle biological invasions. NeoBiota 12: 57-75. doi: 10.3897/neobiota.12.2123 AbstractThe aim of our study is to provide an integrated framework for the management of alien plant invasions, combining insights and experiences from the fields of invasion and restoration ecology to enable more effective management of invasive species. To determine linkages between the scientific outputs of the two disciplines we used an existing data base on restoration studies between 2000 and 2008 and did a bibliometric analysis. We identified the type of restoration applied, determined by the aim of the study, and conducted a content analysis on 208 selected studies with a link to biological invasions (invasion-restoration studies). We found a total of 1075 articles on ecosystem restoration, with only eight percent of the studies having the main objective to control alien invasions. The content analysis of 208 invasion-restoration studies showed that the majority of the studies focused on causes of degradation other than alien invasions. If invaders were referred to as the main driver of degradation, the prevalent cause for degradation was invaders outcompeting and replacing native species. Mechanical control of alien plant invasions was by far the most common control method used. Measures that went beyond the removal of alien plants were implemented in sixty-five percent of the studies.Although invasion control was not as common as other types of restoration, a closer look at the sub-group of invasion-restoration studies shows a clear link between restoration and invasion ecology. Concerns, as identified in the literature review, are firstly that restoration activities mostly focus on controlling the invader while other underlying causes for degradation are neglected, and secondly that the current approach of dealing with alien invasions lacks a combination of theoretical and practical aspects. NeoBiotaMirijam Gaertner et al. / NeoBiota 12: 57-76 (2012) 58We suggest that closer collaboration between invasion and restoration ecologists can help to improve the management of alien plant invasions. We conclude with a framework and a case study from Perth Western Australia integrating the two disciplines, with the aim of informing restoration practice.
