The environmental filtering paradigm and non‐filtering community assembly processes

Journal of Biogeography
AbstractMotivation for abandoning the ‘environmental filtering’ metaphor has been increasing in the literature, yet it remains a widely used conceptual tool to guide research and education within ecological disciplines. I consider the possible origins of the filtering paradigm through linkages to hypotheses about the potentially oversized role of ...

Arctic root‐associated fungal community composition reflects environmental filtering

Molecular Ecology, 2014
AbstractThere is growing evidence that root‐associated fungi have important roles in Arctic ecosystems. Here, we assess the diversity of fungal communities associated with roots of the ectomycorrhizal perennial herbBistorta viviparaon theArctic archipelago ofSvalbard and investigate whether spatial separation and bioclimatic variation are important ...

Phylogenies are relevant when assessing environmental filtering

Folia Geobotanica, 2016
De Bello et al. contemplate the usefulness of phylogenetic corrections in ecological studies involving species traits. They conclude that it is necessary to consider phylogeny when focusing on the evolution of a trait as an adaptation to the environment, but unnecessary when assessing how the composition of traits across a community of species changes ...

Multilayer Filter Coatings with Improved Environmental Stability

Third Topical Meeting on Optical Interference Coatings, 1984
In this paper we report on reactively sputtered optical coatings which are remarkably stable in wavelength performance after extensive temperature cycling and humidity exposure. This exceptional environmental stability makes them particularly well suited for use in optics systems subjected to harsh environments for extended time periods.

Environmental Agricultural Tractor Cab Filter Efficiency and Field Evaluation

AIHA Journal, 2003
To evaluate filter efficiency and performance of environmental enclosures for tractors, 3- to 4-year-old tractor enclosure combinations (cabs retrofitted to tractors after manufacturing) were studied at a custom pesticide applicators facility. Optical particle counters were used to measure the aerosol number concentration inside and outside the cab ...

Stochastic and deterministic processes drive wetland community assembly across a gradient of environmental filtering

Oikos, 2019
The role of deterministic and stochastic processes in community assembly is a key question in community ecology. We evaluated the effect of an abiotic filter (hydroperiod) on the partitioned diversity of three taxonomic groups (birds, vegetation ...

Environmental filtering explains a U-shape latitudinal pattern in regional β-deviation for eastern North American trees.

Ecology Letters, 2018
The underlying drivers of β-diversity along latitudinal gradients have been unclear. Previous studies have focused on β-diversities calculated at a local scale and shed limited light on regional β-diversity.

Environmental impact: Choosing a green filter medium

Filtration & Separation, 2008
There is a huge variety of materials used to construct a filter medium. But with an eye on the environmental impact of the medium, is there a way to make this part greener? Filtration+Separation spoke to Rottneros, a producer of a naturally sourced and green filter medium.

Thin-film optical coating filter stability under different environmental conditions

Applied Optics, 1992
Multilayer coatings have a propensity for the absorption of moisture depending on the porosity and/or density of the materials making up the thin film structure1. To some extent the degree of absorption can determine the durability of the coating and definitely affects the optical performance as the absorbed water molecules fill voids in the materials ...
