The early Eocene greenhouse world was marked by multiple transient hyperthermal events. The most extreme was the Paleocene-Eocene Thermal Maximum (PETM, ~56 Ma), linked to the extinction of the globally recognised deep-sea benthic foraminiferal Velasco fauna, which led to the development of early Eocene assemblages. This turnover has been studied at high resolution, but faunal development into ...

Avian species composition profile and feeding guilds under the aerobic rice field. In Malaysia, productionsystem is an alternative approach to growing in a water-scarce environment. Like irrigated rice, also cansustain diversity of avian fauna. The current status birds fields Malaysia especially ricecondition has not been widely researched. Therefore, this study aims document richness, guildsof...

Carbon dioxide removal (CDR) figures prominently in modelled pathways to achieve the Paris Agreement's goal of limiting global warming 1.5-2°C compared pre-industrial levels. However, national roles and responsibilities deliver CDR have been informed with quota analyses that focus on developed economies major emitters. This study extends discussion implications for developing countries. For pur...

Studies of whether plant community structure and ecosystem properties depend on the genetic diversity of component populations have been largely restricted to species monocultures and have involved levels of genetic differentiation that do not necessarily correspond to that exhibited by neighboring mature individuals in the field. We established experimental communities of varying intraspecific...

AIM The present study addresses the importance of the manager's role in the development and maintenance of organizational culture. It describes the types of cultures that exist and manager characteristics that are essential to facilitating a healthy workplace. BACKGROUND While many managers do not deny the importance of organizational culture in employee satisfaction, few fail to realize the ...

Variations in fish communities of shallow lakes in the Yangtze basins were investigated from September 2007 to September 2009. Six lakes were chosen for comparative study of species composition and diversity in relation to environmental variations. Lake heterogeneity was described with environmental physico-chemical variables, using principal component analysis. Sixteen families, composed of 75...

Plant diversity is affected by spatial variables as well soil physical and chemical variables. In this study, plant species were investigated in five sites of Tabuk Province (Saudi Arabia), namely Aldesah, Alzetah, Alawz, Harra Sharma, to understand if the spatially structured (pH, electric conductivity (EC), texture, calcium, potassium, phosphorus, phosphate, total organic matter (OM), bicarbo...

Knowledge about the diversity and spatiotemporal variability of epiphytic diatom communities in estuarine meadows has great relevance for coastal ecology and, thus, contributes to understanding impact natural anthropogenic changes on seagrass meadows. The community diatoms Ruppia maritima L. was investigated two environments with different levels nutrient loads. Both impacted non-impacted had s...

Braz. J. Aquat. Sci. Technol. 15(1): 54-63. ISSN 1983-9057. Diatoms are good indicators of water quality in lotic systems. The purpose of this study was to provide information about the effects of natural and artificial substrates on diatom-based water quality assessment. Two artificial substrates (bricks and glass) were placed at 6 sampling sites and left for a month during summer base-flow pe...
