According to its owners, the Forest of Seu Nico (FSN) from the Viçosa municipality, Minas Gerais, Brazil, never has been logged and is therefore considered a primary forest. Nevertheless, the forest patch suffered impacts due to selective wood and non-timber extraction, fragmentation and isolation. Aim of this study was to test if the FSN, despite impacts, preserved characteristics of primary forests, which are elevated percentages of non-pioneer (>90%), animal-dispersed (>80 %), understory (>50%) and endemic species (~40%). For that, all trees with diameter at breast height equal or major than 3.2 cm within a plot of 100 x 100 m were identified. With 218 tree species found within this hectare, the FSN's species richness is outstanding for the region. The percentages of non-pioneer (92 %), animal-dispersed (85 %), understory (55 %) and endemic species (39.2 %) from the FSN fulfill the criteria proposed for primary forest. Therefore, we conclude that the FSN maintained its characteristics as a primary forest which highlights its importance for the conservation of biotic resources in the region, where similar fragments are lacking or not described yet.

Karst Citatah region has been known strategies economic value of biotic and a biotic resources. This study investigated plankton biodiversity potency on Cibukur and Cibodas rivers where it already made in Karst Citatah region, particularly on Masigit-Pawon. The result of four stations showed that Karst Masigit-Pawon region was high potency with Plankton biodiversity resources with Diversity and dominancy index almost 1. The numbers of Plankton identified were of 24 species of phytoplankton consist of 9 class and 16 species of zooplankton consists of 6 filum. The high abundance of Plankton was Navicula sp(5.280 species), Synedra sp(4.092 species), dan Cyclops sp(2.904 species) respectively.

The research took place in the Gendol Hill complex, Magelang, Central Java. One of the peaks in the hills complex is Mount Wukir, where a Canggal Inscription was found. The Canggal Inscription mentions an area named Java, rich in agricultural products with many sacred buildings. The term Javanese refers to an area of Gendol Hill complex, which is part of the Kedu–Central Java region. This paper aims to 1) interpret the cultural landscape of the Gendol Hill complex, 2) reconstruct the spatial structure (layout), and its utilization as a settlement area for Javanese society in the 8th century.  This paper interprets the Canggal Inscription and collates information about the potential of both biotic and non-biotic resources. Data processing is conducted through inductive–explanatory analysis. The results suggest that the Cultural Landscape of Gunung Wukir Temple was in a place protecting it from disaster. The complex was protected by Gendol Hills, acting as a barrier against volcanic eruptions from  Mount Merapi. Gendol Hill complex was located in an environment that flourished with both biotic and non-biotic resources. The community cultivated its alluvial plains and established settlements in this area. The denuded structural hills were also perceived as sacred spaces to erect temples with natural resources close by such as andesite rocks available from rivers around the hills.

The pages which follow are a report of the findings from a series of archeological excavations in western Utah. The archeological sites were Danger (42To13), Juke Box (42To20), and Raven (24EK2) caves. Of these three Danger Cave was the most informative and lends its name to the report. Juke Box and Raven provided interesting problems in excavation, but their evidence as to cultural events was meager.The human story inferred in this report was set in one of the most remarkable of North American environments—the desert West. The natural subsistence resources of this land are today quite sparse; the balance between success and failure in survival has always been delicate. The fact that human groups survived in this environment deserves serious ecological note. Although no intensive study of this aspect of the problem is being undertaken here, the cultural data cannot be appreciated or evaluated without a modicum of information regarding the terrain and the biotic resources of the region.

Abstract Antarctic krill (Euphausia superba) is one of the most successful species on Earth and serves as the largest potential protein bank for both Antarctic animals and humans. Research on this species is of great value for exploitation of Antarctic biotic resources. In this study, the metabolomics of E. superba were investigated using the GC-MS method. A total of 293 compounds were initially identified; these compounds could be divided into several classes, including amino acids, sugars and polyols, metabolic intermediates, small molecules and other metabolites. However, a serious problem was that both 2-hydroxybiphenyl and dioctyl phthalate were also detected in these krill tissues. Moreover, some intermediates of pesticides and medicinal or chemical compound products were found in krill tissue as well. This is the first survey to investigate the occurrence of chemical contamination in metabolites of Antarctic krill. These findings suggest that international contracts or policies should be developed to protect the pristine ocean.
