Multiple configurations and fluctuating trophic control in the Barents Sea food-web.

PLoS ONE, 2021
The Barents Sea is a subarctic shelf sea which has experienced major changes during the past decades. From ecological time-series, three different food-web configurations, reflecting successive shifts of dominance of pelagic fish, demersal fish, and ...

Exploitation, secondary extinction and the altered trophic structure of Jamaican coral reefs [PDF]

, 2010
Coral reef communities of the Greater Antilles in the Caribbean have a long history of anthropogenic disturbance, driven by the exploitation for food of both vertebrate and invertebrate species.

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

Advanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Exploring the trophic interactions in the coral reef ecosystem at the coastal area of Ternate Island using Ecopath model

Depik Jurnal
The Ecopath mass-balanced model was employed to elucidate the trophic structure and interaction, energy flow, and ecosystem properties of the coral reef ecosystem in the coastal area of Ternate Island. The model comprised 30 functional ecological groups,

Linking Carbon-Nitrogen-Phosphorus Cycle and Foodweb Models of an Estuarine Lagoon Ecosystem

Computational Science and Techniques, 2015
In this study, an NPZD model and a trophic network model that contains organism groups on the higher trophic levels were developed and linked using the “bottom-up control” approach.

Computer simulations of history of life: speciation, emergence of complex species from simpler organisms, and extinctions

, 2003
We propose a generic model of eco-systems, with a {\it hierarchical} food web structure. In our computer simulations we let the eco-system evolve continuously for so long that that we can monitor extinctions as well as speciations over geological time ...

Deleting species from model food webs [PDF]

, 2004
We use food webs generated by a model to investigate the effects of deleting species on other species in the web and on the web as a whole. The model incorporates a realistic population dynamics, adaptive foragers and other features which allow for the ...

Long‐Term Effects of Xenotransplantation of Human Enteric Glia in an Immunocompetent Rat Model of Acute Brain Injury

Advanced Science, EarlyView.
Acute brain injuries are characterized by extensive tissue damage, resulting in debilitating deficits in patients. Despite considerable progress, cell‐based approaches have yet to identify an ideal candidate. This long‐term study explores the use of an untested cell source – human enteric glia – and a non‐invasive administration route – intranasal ...

Trophic levels of fish species of commercial importance in the Colombian Caribbean

Revista de Biología Tropical, 2011
Ecological studies on commercial important fish species are of great value to support resource management issues. This study calculated trophic levels of those Colombian Caribbean fish species whose diet has been locally described.

Trophic model closure influences ecosystem response to enrichment

Ecological Modelling, 2023
There exists considerable uncertainty about the most appropriate functional form to describe mortality at the highest trophic level (the closure problem). Although linear and quadratic formulations predict strongly different dynamics, it is unclear which of these formulations is more realistic.
