Bioaccumulation and Trophic Transfer of Emerging Organophosphate Flame Retardants in the Marine Food Webs of Laizhou Bay, North China.

Environmental Science and Technology, 2019
Despite the increase in production, usage, and discharge of organophosphate flame retardants (OPFRs), little information is available about their bioaccumulation and trophic transfer in the marine food web.

A game demonstrating aspects of bumblebee natural history [PDF]

, 2004
The Bumblebee Game is an exciting outdoor game, which demonstrates aspects of bumblebee natural history including food chains, food webs and competition for food, predation by crab spiders, parasitism by Conopidae (Diptera) and brood parasitism by ...

A diverse suite of pharmaceuticals contaminates stream and riparian food webs

Nature Communications, 2018
A multitude of biologically active pharmaceuticals contaminate surface waters globally, yet their presence in aquatic food webs remain largely unknown.

What constrains food webs? A maximum entropy framework for predicting their structure with minimal biases.

PLoS Computational Biology, 2023
Food webs are complex ecological networks whose structure is both ecologically and statistically constrained, with many network properties being correlated with each other.

Food-web structure in relation to environmental gradients and predator-prey ratios in tank-bromeliad ecosystems [PDF]

, 2013
Little is known of how linkage patterns between species change along environmental gradients. The small, spatially discrete food webs inhabiting tank-bromeliads provide an excellent opportunity to analyse patterns of community diversity and food-web ...

Accumulation of Plastic Debris and Associated Contaminants in Aquatic Food Webs

Environmental Science and Technology, 2018
We present a generic theoretical model (MICROWEB) that simulates the transfer of microplastics and hydrophobic organic chemicals (HOC) in food webs. We implemented the model for an Arctic case comprised of nine species including Atlantic cod and polar ...

Compilation and network analyses of cambrian food webs. [PDF]

PLoS Biology, 2008
A rich body of empirically grounded theory has developed about food webs--the networks of feeding relationships among species within habitats. However, detailed food-web data and analyses are lacking for ancient ecosystems, largely because of the low ...

Food-web structure of seagrass communities across different spatial scales and human impacts. [PDF]

PLoS ONE, 2011
Seagrass beds provide important habitat for a wide range of marine species but are threatened by multiple human impacts in coastal waters. Although seagrass communities have been well-studied in the field, a quantification of their food-web structure and

Using food-web theory to conserve ecosystems [PDF]

, 2015
© 2016, Nature Publishing Group. All rights reserved.Food-web theory can be a powerful guide to the management of complex ecosystems. However, we show that indices of species importance common in food-web and network theory can be a poor guide to ...
