Spatial and temporal variability of macrobenthic communities in Chalus Shore of the Caspian Sea

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2011
The changes in density and biomass of macrobenthos were seasonally investigated from winter 2005 till fall 2006 in southern Caspian Sea. Samples were taken with a 225cm2 Van Veen grab from depths of 7 and 20 meters along two transects: Line 8 area ...

Nitrogen additions and microbial biomass: a meta-analysis of ecosystem studies.

open access: yesEcology Letters, 2008
Nitrogen (N) enrichment is an element of global change that could influence the growth and abundance of many organisms. In this meta-analysis, I synthesized responses of microbial biomass to N additions in 82 published field studies.

Biomass‐Derived Metal‐Free Nanostructured Carbon Electrocatalysts for High‐Performance Rechargeable Zinc–Air Batteries

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The study discusses synthesis strategies of metal‐free heteroatom‐doped nanocarbon materials from biomass for use in rechargeable zinc–air batteries. It also covers the significance of these materials as electrocatalysts and electrodes for improving the oxygen reduction and evolution reactionsin.

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Environmental variation, functional diversity and identity predicting community biomass in an old-growth subtropical broad-leaved forest

open access: yesGlobal Ecology and Conservation, 2020
The relationship between biodiversity and ecosystem functioning (BEF) has emerged as a central issue in ecosystem ecology. Two broad classes of hypotheses, the mass ratio and niche complementarity effects, are proposed to explain the positive relation ...
