Borneo coral reefs subject to high sediment loads show evidence of resilience to various environmental stressors [PDF]

open access: yes, 2019
For reefs in South East Asia the synergistic effects of rapid land development, insufficient environmental policies and a lack of enforcement has led to poor water quality and compromised coral health from increased sediment and pollution.

A Hybrid Particle Swarm Optimisation-Genetic Algorithm for Multi-objective Reservoir Ecological Dispatching

open access: yesWater Resources Management, 2022
Abstract Reservoir ecological dispatching is a complex system problem with multi-objective, multiple-criteria and multiple-phase. This study establishes a multi-objective ecological dispatching model in Changchun city of Yinma River Basin based on the water demand of social economic development, river ecology, and the constraint of reservoir ...

Can aggregate quarry silt lagoons provide resources for wading birds? [PDF]

open access: yes, 2017
Wading birds have declined across Europe as the intensification of lowland agriculture has resulted in the loss and degradation of wetland areas. Lowland aggregate extraction sites that incorporate areas of fine, waste sediments deposited in silt lagoons

Study on Characteristic Spectrum and Multiple Classifier Fusion With Different Particle Size in Marine Sediments

open access: yesIEEE Access, 2020
Marine sediments record much information of the ecological process, which highly correlated with global and local environmental change. Particle size and its distributions of sediments indicate different ecological functions, thus are the key questions ...

Spatial patterns of competing random walkers [PDF]

open access: yes, 2014
We review recent results obtained from simple individual-based models of biological competition in which birth and death rates of an organism depend on the presence of other competing organisms close to it.

On predicting particle capture rates in aquatic ecosystems.

open access: yesPLoS ONE, 2021
Recent advances in understanding the capture of moving suspended particles in aquatic ecosystems have opened up new possibilities for predicting rates of suspension feeding, larval settlement, seagrass pollination and sediment removal. Drawing on results

Suspended particulates mediate bacterial community coalescence in different habitats of a large sediment-laden river

open access: yesEcological Indicators, 2022
Many studies have reported the influence of dispersal processes on aquatic bacterial communities, but the role of community coalescence is still unknown in sediment-laden rivers.

Density-and trait-mediated effects of a parasite and a predator in a tri-trophic food web [PDF]

open access: yes, 2014
1. Despite growing interest in ecological consequences of parasitism in food webs, relatively little is known about effects of parasites on long-term population dynamics of non-host species or about whether such effects are density- or trait- mediated ...
