Periphyton: ecology, exploitation and management

, 2005
This book contains 18 chapters and provides an international review of periphyton ecology, exploitation and management. The ecological aspect focuses on periphyton structure and function in natural systems while the exploitation aspect covers its ...

Food web architecture and basal resources interact to determine biomass and stoichiometric cascades along a benthic food web. [PDF]

PLoS ONE, 2011
Understanding the effects of predators and resources on primary producers has been a major focus of interest in ecology. Within this context, the trophic cascade concept especially concerning the pelagic zone of lakes has been the focus of the majority ...

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Comparison of Periphyton Biomass on Coconut Coir and Bamboo Poles as Natural Substrates in Earthen Lined Pond

International Journal of Bio-Resource and Stress Management, 2020
As a first step in assessing the viability of periphyton-based shrimp production in lined pond aquaculture systems, the effects of natural substrates (split bamboo poles and coconut coir) on development of periphyton were evaluated.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Carbonate sediment production in coastal wetlands: Periphyton contributions and diatom indicators

Ecological Indicators
Coastal ecosystems rapidly transform as sea levels rise faster than ecosystems can build elevation through biological processes that accrete organic matter and inorganic sediment.

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

付着藻類の一次生産および種間競争に関する数値解析 [PDF]

, 2005
A numerical simulation model is presented to describe primary production and species transition of stream periphyton communities, in which the net growth rate of periphyton biomass is estimated by the balance of primary production, immigration ...

THE MASS RATIO OF THE EPIPHYTIC PERIPHYTON OF THE NYÉKI-HOLT-DUNA [PDF]

Acta Geographica Debrecina. Landscape & Environment Series, 2016
The knowledge of the periphytic structure is important for the fact that the composition of epiphytic periphyton indicates the ecologically different habitats, the biological state of water-quality and its changes.

The effects of Bacillus thuringiensis var. israelensis (Bti) on tropical stream food webs vary between two consecutive dry seasons

Insect Conservation and Diversity, EarlyView.
Bti application altered tropical stream food‐web structure through changes in macroinvertebrate functional feeding groups. Collector‐filterers and predators showed context‐dependent responses, with clearer direct and indirect effects detected in 2016, the year with higher rainfall.
