Rhizoremediation potential of different wild plant species for total (aliphatic) petroleum hydrocarbon (TPH)-contaminated soils was investigated. Three-week-old seedlings Acacia inaequilatera, pyrifolia, stellaticeps, Banksia seminuda, Chloris truncata, Hakea prostrata, Hardenbergia violacea, and Triodia wiseana were transplanted in a soil contaminated with diesel engine oil as TPH at pollution...

CAM 식물은 야간에 기공을 열어 CO2를 흡수하는 식물로 환기하지 않는 시설 내 발생한 잉여 광합성에 이용할 수 있다. 게발선인장은 다화성으로, 엽상경 수가 많을수록 상품성이 높아진다. 본 연구는 게발선인장의 야간 CO2 시비 적용 가능성을 파악하기 위하여 생육 적정 환경인 생육상과 실제 농가의 환경에 따른 온실에서 엽상경별 광합성 특성을 조사하였다. 생육상 게발선인장 상위 엽상경은 주간에만 흡수를 하는 C3 보였으며, 2차 주/야간 모두 C3–CAM 보였다. 하지 않았으나, 기공전도도와 수분이용효율은 온실 식물에 비하여 모든 엽상경에서 높은 값을 나타냈다. 특성이 나타나는 엽상경에 높았다. 일일 총 흡수율은 식물에서 더 높게 나타났으며, 값이 155mmol·m–2·d–1로 가장 ‘핑크듀’는 성숙한 ...

Analyses of long-term ecosystem dynamics offer insights into the conditions that have led to stability vs. rapid change in the past and the importance of disturbance in regulating community composition. In this study, we (1) used lithology, pollen, and charcoal data from Mallín Casanova (47S) to reconstruct the wetland, vegetation, and fire history of west-central Patagonia; and (2) compared th...

In this paper we present the first automatically constructed LASCO CME catalog, a result of the application of the Computer Aided CME Tracking software (CACTus) on the LASCO archive during the interval September 1997-January 2007. We have studied the CME characteristics and have compared them with similar results obtained by manual detection (CDAW CME catalog). On average CACTus detects less th...

BACKGROUND AND AIMS The endemic tree Nothofagus alessandrii (Fagaceae) has been historically restricted to the coastal range of Region VII of central Chile, and its forests have been increasingly destroyed and fragmented since the end of the 19th century. In this study, the patterns of within- and among-population genetic diversity in seven fragments of this endangered narrowly endemic tree wer...
