Preliminary trophic network analysis of subalpine Lake Annecy (France) using an Ecopath model [PDF]

Knowledge and Management of Aquatic Ecosystems, 2009
Lake Annecy is the second largest natural lake in France, with intensive commercial and recreational fisheries. However, there is limited knowledge of its trophic interaction. A preliminary Ecopath model was fitted to study the trophic interaction in the

A Stepwise Fitting Procedure for automated fitting of Ecopath with Ecosim models

SoftwareX, 2016
The Stepwise Fitting Procedure automates testing of alternative hypotheses used for fitting Ecopath with Ecosim (EwE) models to observation reference data (Mackinson et al. 2009).

Beyond the Meal: Trophic Controls by Pelagic and Demersal Chondrichthyes in Two Different Mediterranean Marine Food Webs. [PDF]

Ecol Evol
Pelagic and demersal sharks played different top‐down controls in the food web. Pelagic sharks act as apex predators impacting mesoconsumers. Trophic controls patterns by demersal sharks change according to ecosystem traits. ABSTRACT Pelagic and demersal Chondrichthyes can assume different patterns of trophic controls on marine food webs, sustaining ...

High-throughput microfluidic real-time PCR as a promising tool in disease ecology. [PDF]

J Anim Ecol
This work highlights the diversity of disease ecology questions Htrt PCR could contribute to addressing in a given host–pathogen ecosystem. This tool could be used to answer a broad set of basic and applied questions in animal ecology, notably by providing a way to address issues involving communities of hosts and communities of pathogens.

Facilitative interspecific interactions in marine vertebrates across scales: from individuals to ecosystems. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Facilitative interspecific interactions (FIIs) confer benefits to at least one participant without detriment to others. Although often less emphasised than antagonistic interactions in ecological studies, this review highlights the significant ecological role of FIIs across biological scales – from individual behaviours to population ...

Cumulative Extreme Events Threaten Penguin Habitats Across the Southern Hemisphere. [PDF]

Glob Chang Biol
This study examines how multiple extreme events overlap across the Southern Hemisphere, focusing on hotspots of 18 penguin species across both land and sea. African, Snares, Emperor, Adélie and Galápagos penguins experience the greatest combined exposure, and most species are projected to face more frequent extremes if current trends persist.

Environmental and human factors shape the trophic ecology of a widespread marine predator. [PDF]

J Anim Ecol
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Modelling the Mediterranean Sea ecosystem at high spatial resolution to inform the ecosystem-based management in the region

Scientific Reports, 2022
Cumulative pressures are rapidly expanding in the Mediterranean Sea with consequences for marine biodiversity and marine resources, and the services they provide. Policy makers urge for a marine ecosystem assessment of the region in space and time.
