Food web functional responses

open access: yesFrontiers in Ecology and Evolution, 2022
This article reviews the nature of functional responses that have commonly been used to represent feeding relationships in the ecological literature. It compares these with the range of functional response forms that are likely to characterize species in

Effects of Commercial Arbuscular Mycorrhizal Inoculants on Plant Productivity and Intra-Radical Colonization in Native Grassland: Unintentional De-Coupling of a Symbiosis?

open access: yesPlants, 2022
There has been a surge in industries built on the production of arbuscular mycorrhizal (AM) fungal-based inoculants in the past few decades. This is not surprising, given the positive effects of AM fungi on plant growth and nutritional status.

The urea cycle of rat white adipose tissue [PDF]

open access: yesRSC Advances, 2015
White adipose tissue (WAT) contains a powerful metabolic machinery related to energy metabolism and partition. The adaptive, regulatory, size and structural variety of WAT agrees with this control role.

Effects of water movement and temperature on Rhizophydium infection of Planktothrix in a shallow hypereutrophic lake

open access: yesFrontiers in Microbiology, 2023
Grand Lake St. Marys (GLSM) is a popular recreational lake located in western Ohio, United States, generating nearly $150 million in annual revenue. However, recurring algal blooms dominated by Planktothrix agardhii, which can produce harmful microcystin

Phytoplankton fuels Delta food web

open access: yesCalifornia Agriculture, 2003
Populations of certain fishes and invertebrates in the Sacramento-San Joaquin Delta have declined in abundance in recent decades and there is evidence that food supply is partly responsible.

Dispersal Dynamics in Food Webs [PDF]

open access: yesThe American Naturalist, 2015
Studies of food webs suggest that limited nonrandom dispersal can play an important role in structuring food webs. It is not clear, however, whether density-dependent dispersal fits empirical patterns of food webs better than density-independent dispersal.

Aquatic Invasions! A Menace to the West : Food Web Invaders

open access: yes
Discover how a food web works by making a live model, using the people in your class. Then explore how an invasive species disrupts that balance.-- STEAM Topics: Ecology, biology-- Grades 4-

Dynamics of Simple Food Webs [PDF]

open access: yesBulletin of Mathematical Biology, 2015
We consider a simple food web with commensal relationship, where organisms utilize both external resources and resources produced by other organisms. We show that in such a community with no competition, there is at most one possible equilibrium for each fixed set of surviving species, and develop a natural condition that determines which species ...

Trophic Diversity and Food Web Structure of Vegetated Habitats Along a Coastal Topographic Gradient

open access: yesFrontiers in Marine Science, 2022
Land–sea interactions in coastal wetlands create heterogeneous vegetated habitats with regular zonation along a topographic gradient. However, it’s unclear how the trophic diversity of communities and trophic structure of food webs change along the ...

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

open access: yes, 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 ...
