Analysis of Energy Flow in US GLOBEC Ecosystems Using End-to-End Models [PDF]

open access: yesOceanography, 2013
End-to-end models were constructed to examine and compare the trophic structure and energy flow in coastal shelf ecosystems of four US Global Ocean Ecosystem Dynamics (GLOBEC) study regions: the Northern California Current, the Central Gulf of Alaska ...

Predicting plankton net community production in the Atlantic Ocean [PDF]

open access: yes, 2009
We present, test and implement two contrasting models to predict euphotic zone net community production (NCP), which are based on 14C primary production (PO14CP) to NCP relationships over two latitudinal (ca.

"Freshwater killer whales": beaching behavior of an alien fish to hunt land birds [PDF]

open access: yes, 2012
The behavioral strategies developed by predators to capture and kill their prey are fascinating, notably for predators that forage for prey at, or beyond, the boundaries of their ecosystem.

Diet reconstruction and resource partitioning of a Caribbean marine mesopredator using stable isotope bayesian modelling. [PDF]

open access: yesPLoS ONE, 2013
The trophic ecology of epibenthic mesopredators is not well understood in terms of prey partitioning with sympatric elasmobranchs or their effects on prey communities, yet the importance of omnivores in community trophic dynamics is being increasingly ...

Automated extraction of fungal trophic modes from literature using BioBERT: an open pilot workflow [PDF]

open access: yesResearch Ideas and Outcomes
Fungi exhibit diverse trophic strategies, ranging from obligate symbiosis to saprotrophy, with some taxa capable of occupying multiple ecological roles.

Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]

open access: yes, 2003
1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.

Trophic Models of Seagrass Ecosystems in Maqueda Channel, Caramoan Peninsula, Philippines

open access: yesApplied Environmental Research, 2019
Steady-state trophic models were constructed using the Ecopath with Ecosim software to examine the general status, development trends, and functional integrity of three extensive seagrass meadows located in Maqueda Channel of Caramoan Peninsula ...

Catastrophic regime shifts in model ecological communities are true phase transitions [PDF]

open access: yes, 2010
Ecosystems often undergo abrupt regime shifts in response to gradual external changes. These shifts are theoretically understood as a regime switch between alternative stable states of the ecosystem dynamical response to smooth changes in external ...

Evolutionary Stability of Ecological Hierarchy [PDF]

open access: yes, 2003
A self-similar hierarchical solution that is both dynamically and evolutionarily stable is found to the multi dimensional Lotka-Volterra equation with a single chain of prey-predator relations.
