Experimental parameters defining ultra-low biomass bioaerosol analysis

npj Biofilms and Microbiomes, 2021
Investigation of the microbial ecology of terrestrial, aquatic and atmospheric ecosystems requires specific sampling and analytical technologies, owing to vastly different biomass densities typically encountered.

Sustainable Power Production in a Membrane-less and Mediator-less Wastewater Microbial Fuel Cell [PDF]

, 2009
Microbial fuel cells (MFCs) fed with wastewater are currently considered a feasible strategy for production of renewable electricity at low cost. A membrane-less MFC with biological cathode was built from a compact wastewater treatment reactor.

Species richness and food-web structure jointly drive community biomass and its temporal stability in fish communities.

Ecology Letters, 2021
Biodiversity-ecosystem functioning and food-web complexity-stability relationships are central to ecology. However, they remain largely untested in natural contexts.

Evidence for an ecological cost of enhanced herbicide metabolism in Lolium rigidum [PDF]

, 2009
1. In some cases, evaluation of resource competitive interactions between herbicide resistant vs. susceptible weed ecotypes provides evidence for the expression of fitness costs associated with evolved herbicide-resistant gene traits. Such fitness costs

Estimating ecological production from biomass [PDF]

Ecosphere, 2015
Productivity‐diversity relationships (P/D) are a vital theme in ecology, but productivity is typically not measured directly in that research. Instead, biomass (B) is the most common proxy for productivity, often as a 1:1 substitute. Unfortunately, this practice may cause error and uncertainty in P/D research, due to the fundamental difference between ...

Sources and modes of action of invasive knotweed allelopathy : the effects of leaf litter and trained soil on the germination and growth of native plants [PDF]

, 2012
Invasive knotweeds, native to Eastern Asia, are among the most dominant plant invaders of European and North American temperate ecosystems. Recent studies indicate that one cause of this dominance might be allelopathy, but the possible sources and modes ...

The biomass–density relationship in seagrasses and its use as an ecological indicator [PDF]

BMC Ecology, 2018
Biomass-density relations have been at the centre of a search for an index which describes the health of seagrass meadows. However, this search has been complicated by the intricacy of seagrass demographics and their complex biomass-density relations, a consequence mainly of their modular growth and clonality.

How self-regulation, the storage effect and their interaction contribute to coexistence in stochastic and seasonal environments [PDF]

, 2019
Explaining coexistence in species-rich communities of primary producers remains a challenge for ecologists because of their likely competition for shared resources.

Effects of Environmental Factors on Plant Productivity in the Mountain Grassland of the Mountain Zebra National Park, Eastern Cape, South Africa

Ecologies, 2023
The relationship between plant productivity, measured according to biomass and species richness, is a fundamental focal point in community ecology, as it provides the basis for understanding plant responses or adaptive strategies.

The Pongola Bush: Tree diversity assessment in a KwaZulu-Natal forest patch

Koedoe: African Protected Area Conservation and Science, 2022
The Pongola Bush Nature Reserve lies in a narrow band along the escarpment between Mpumalanga and KwaZulu-Natal (KZN). Although referred to as ‘bush’, this vegetation type may be considered to fit into the intersection of two types of scarp forest: the ...
