Abstract Since European settlement of Australia, substantial areas subtropical rainforest have been cleared. More recently, effort is being made to restore small this biodiverse ecological community.

Wild restored populations these species were sampled compared two neighbouring regions Northeast New South Wales (the Tweed Caldera Big Scrub).

Abstract. Supartono T, Adhya I, Kosasih D, Wildani W. 2023. Tree species diversity adapted to Pinus merkusii forests in Gunung Ciremai National Park, West Java, Indonesia. Biodiversitas 24: 4314-4323. One of the challenges faced rehabilitating pine conservation areas is limited information on plant capable adapting these ecosystems. This study aimed analyze tree that grow and adapt relationship natural with vegetation characteristics forests. The research was conducted bordering far from using sample plot method. recorded 44 27 families seedlings, 46 21 saplings, 25 18 poles, 24 17 trees. Accumulation all growth stages 83 (76 local 7 cultivated species) 39 families. Based accumulation curve, adjacent have more than those Individual family density were also higher two variables Furthermore, both forest forest, each has its own peculiarities. results indicate existence an important role as a source biodiversity for surrounding ecosystem. As implication this study, can level poles trees be recommended rehabilitation plants Jungh. & de Vriese Indonesia because not allelopathy it releases reduce diversity.

Abstract One of the greatest tragedies in Brazilian mining history occurred November 2015 Mariana, Minas Gerais state, when a dam from company Samarco was breached. Millions mine tailings this upstream embankment were dumped over Doce River basin, impacting an area approximately 1469 ha riparian vegetation. Our objective to experimentally investigate whether plant recruitment and establishment are impaired areas affected by six years after deposition. To achieve goal, 2021 we compared soil chemical properties between unaffected areas, performed seed bank experiment controlled conditions, conducted greenhouse growth using two most abundant species. Affected soils presented lower fertility organic matter content. At same time, mean abundance richness emerging plants did not differ soils. Still, exhibited 35% accumulated species (gamma diversity) than ones. The three both represented 34% individuals, being Marsypianthes chamaedrys (Vahl) Kuntze, Ludwigia octovalvis (Jacq.) P.H. Raven Ageratum conyzoides L. In experiment, growing reduced height stem diameter increment ( ) or allocated fewer resources root production aerial parts M. chamaedrys) , potentially response infertility density. Even years, our results showed that tailings- continue experience negative impacts on recruitment, highlighting its adverse effects ecosystem functions services.

Torch ginger – bak-kala (Etlingera elatior (Jack) R.M.SM.) already has been proven an effective traditional medicine by tribes in Aceh Province, Indonesia. Solid primary evidence for the torch ginger, bak-kala’s medicinal properties include healing effects experienced Aceh, when treated illnesses, such as, cough, fever, and sprains. Likewise, it to be a use food ingredients, i.e., vegetables spices enhance taste of food. Much available documented information focused on its biochemical pharmacological aspects. Even though utilization resources is mainly at level diversity, there no genetic diversity Aceh. The high intensity not simultaneous with diversity. On other hand, many uses are specific certain accessions particular benefits. study aimed create classification system variations based inter-simple sequence repeats (ISSR) markers provide Province. 35 were divided into eight populations geographical locations from which they collected. Data recorded analyzed using 10 ISSR primers 77 total bands. molecular characters four major groups. As revealed expected heterozygosity (He), variability among population showed that Simeulu possessed greater than populations. results analysis variation (AMOVA) within was higher (60%) (40%). studies can used plan conservation strategies, optimal species, crop improvement programs future.
