For the Poplar Box Grassy Woodland on Alluvial Plains Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) (s266B) Conservation Advice (including listing advice) for the Poplar Box Grassy Woodland on Alluvial Plains 1 The Threatened Species Scientific Committee (the Committee) was established under the EPBC Act to give advice to the Minister for the Environment (the Minister) in relation to the listing and conservation of threatened ecological communities, including under sections 189, 194N and 266B of the EPBC Act. 2. The Committee provided its advice on the Poplar Box Grassy Woodland on Alluvial Plains ecological community to the Minister as a draft of this conservation advice in April 2017, an updated version in April 2018 and also in June 2019. The Committee recommended that: o the ecological community merits listing as endangered under the EPBC Act; and o a recovery plan is not required for the ecological community at this time. 3. A draft conservation advice for this ecological community was made available for expert and public comment for a minimum of 30 business days. The Committee and Minister had regard to all public and expert comment that was relevant to the consideration of the ecological community. 4. In 2019, the Minister accepted the Committee’s advice, adopted this document as the approved conservation advice and agreed no recovery plan is required at this time. The Minister amended the list of threatened ecological communities under section 184 of the EPBC Act to include the Poplar Box Grassy Woodland on Alluvial Plains ecological community in the endangered category. 5. At the time of this advice, components of this ecological community were also listed under the Queensland Vegetation Management Act 1999. 6. This approved conservation advice was based on the best available information at the time it was approved; this includes scientific literature, advice from consultations, and existing plans, records or management prescriptions for this ecological community.

    Nat. Prod. Bioprospect. DOI 10.1007/s13659-017-0123-0 REVIEW The Genus Carissa: An Ethnopharmacological, Phytochemical and Pharmacological Review Joseph Sakah Kaunda . Ying-Jun Zhang Received: 9 December 2016 / Accepted: 13 February 2017 Ó The Author(s) 2017. This article is published with open access at Springerlink.com Abstract Carissa L. is a genus of the family Apocynaceae, with about 36 species as evergreen shrubs or small trees native to tropical and subtropical regions of Africa, Asia and Oceania. Most of Carissa plants have been employed and utilized in traditional medicine for various ailments, such as headache, chest complains, rheumatism, oedema, gonorrhoea, syphilis, rabies. So far, only nine Carissa species have been phytochemically studied, which led to the identification of 123 compounds including terpenes, flavonoids, lignans, sterols, simple phenolic compounds, fatty acids and esters, and so on. Pharmacological studies on Carissa species have also indicated various bioactive potentials. This review covers the peer- reviewed articles between 1954 and 2016, retrieved from Pubmed, ScienceDirect, SciFinder, Wikipedia and Baidu, using ‘‘Carissa’’ as search term (‘‘all fields’’) and with no specific time frame set for search. Fifteen important medicinal or ornamental Carissa species were selected and summarized on their botanical characteristics, geographical distribution, traditional uses, phytochemistry, and pharmacological activities.

E-mail address: [email protected] Keywords: Fruiting phenology, Scrub forest, Eastern Ghats, India ABSTRACT. This paper describes the fruiting phenology of 110 individuals of woody species belonging to 22 taxa (21 species, 1 variety) belonging to 15 families including 2 species of figs in a scrub forest, Thiruporur, Eastern Ghats. Fruiting peak was observed during July 2009 with 11 species in fruiting, a dip was observed during March 2009 where only 2 species were in fruiting. Season wise fruiting peak was observed during South-west and North-east Monsoon while the dip was during summer. 1.INTRODUCTION Phenology is the study of relationship between climatic factors and periodic phenomena in organisms. Periodic behaviour of plants in tropical environments has received much attention in recent years. Tropical forests with their high level of species diversity, display phenological events such as leaf drop, leaf flushing, flowering and fruiting, etc. in relation to time and space [1]. Study of such events is useful in evolving proper management strategy as well as better understanding of natural forest regeneration potential and community level interactions [2].

  • Investigation of Mitochondrial-Derived Plastome Sequences in the Paspalum Lineage (Panicoideae; Poaceae) Sean V
    Burke et al. BMC Plant Biology (2018) 18:152 https://doi.org/10.1186/s12870-018-1379-1 RESEARCH ARTICLE Open Access Investigation of mitochondrial-derived plastome sequences in the Paspalum lineage (Panicoideae; Poaceae) Sean V. Burke1* , Mark C. Ungerer2 and Melvin R. Duvall1 Abstract Background: The grass family (Poaceae), ca. 12,075 species, is a focal point of many recent studies that aim to use complete plastomes to reveal and strengthen relationships within the family. The use of Next Generation Sequencing technology has revealed intricate details in many Poaceae plastomes; specifically the trnI - trnL intergenic spacer region. This study investigates this region and the putative mitochondrial inserts within it in complete plastomes of Paspalum and other Poaceae. Results: Nine newly sequenced plastomes, seven of which contain an insert within the trnI - trnL intergenic spacer, were combined into plastome phylogenomic and divergence date analyses with 52 other species. A robust Paspalum topology was recovered, originating at 10.6 Ma, with the insert arising at 8.7 Ma. The alignment of the insert across Paspalum reveals 21 subregions with pairwise homology in 19. In an analysis of emergent self- organizing maps of tetranucleotide frequencies, the Paspalum insert grouped with mitochondrial DNA. Conclusions: A hypothetical ancestral insert, 17,685 bp in size, was found in the trnI - trnL intergenic spacer for the Paspalum lineage. A different insert, 2808 bp, was found in the same region for Paraneurachne muelleri. Seven different intrastrand deletion events were found within the Paspalum lineage, suggesting selective pressures to remove large portions of noncoding DNA. Finally, a tetranucleotide frequency analysis was used to determine that the origin of the insert in the Paspalum lineage is mitochondrial DNA.
