Integrating functional diversity, food web processes, and biogeochemical carbon fluxes into a conceptual approach for modeling the upper ocean in a high-CO2 world [PDF]

, 2005
Marine food webs influence climate by channeling carbon below the permanent pycnocline, where it can be sequestered. Because most of the organic matter exported from the euphotic zone is remineralized within the "upper ocean" (i.e., the water column ...

OTUD6A in Airway Epithelial Cells Exacerbates Allergic Asthma by Promoting Airway Inflammation and Airway Remodeling Through Deubiquitination of hResistin/mRELMα

Advanced Science, EarlyView.
This study elucidates a novel mechanistic role of the deubiquitinase OTUD6A in asthma pathogenesis, uncovering its regulatory function in airway inflammation and airway remodeling through the stabilization of hResistin/mRELMα. This study offers a novel regulatory axis (OTUD6A‐hResistin/mRELMα) in asthma pathogenesis and OTUD6A inhibition as a potential

Diagnosis of planktonic trophic network dynamics with sharp qualitative changes

Peer Community Journal
Trophic interaction networks are notoriously difficult to understand and to diagnose (i.e., to identify contrasted network functioning regimes). Such ecological networks have many direct and indirect connections between species, and these connections are

Ecological Network Inference From Long-Term Presence-Absence Data

Scientific Reports, 2017
Ecological communities are characterized by complex networks of trophic and nontrophic interactions, which shape the dy-namics of the community. Machine learning and correlational methods are increasingly popular for inferring networks from co-occurrence

Delineating reef fish trophic guilds with global gut content data synthesis and phylogeny.

PLoS Biology, 2020
Understanding species' roles in food webs requires an accurate assessment of their trophic niche. However, it is challenging to delineate potential trophic interactions across an ecosystem, and a paucity of empirical information often leads to ...

Modelling diet composition dynamics among North Sea predatory fish using a length-structured partial ecosystem model [PDF]

, 2012
Multispecies fisheries management approaches must take account of the array of trophic interactions within the ecosystem. Studies of the gut contents of fish stocks in the North Sea show decadal changes in diet composition, as might be expected when the ...

Species assembly in model ecosystems, II: Results of the assembly process [PDF]

, 2010
In the companion paper of this set (Capitan and Cuesta, 2010) we have developed a full analytical treatment of the model of species assembly introduced in Capitan et al. (2009).

Reducing the Eltonian shortfall with trophic interaction models

, 2021
While species interactions are fundamental for linking biodiversity to ecosystem functioning and for conservation, large-scale empirical data are lacking for most species and ecosystems. Accumulating evidence suggests that trophic interactions are predictable from available functional trait information, but we have yet to understand how well we can ...

OCTN2 Activates a Non‐Canonical Carnitine Metabolic Pathway to Promote MASH‐HCC Progression and Immunotherapy Resistance

Advanced Science, EarlyView.
In non‐MASH‐HCC, L‐carnitine promotes tumor progression primarily through its classical role in enhancing fatty acid oxidation (FAO). However, in MASH‐HCC, where FAO is markedly suppressed, L‐carnitine shifts from this canonical function to serve instead as an intracellular acetyl group buffer.

Trophic status and fish production potential of Golbolagh Lake (West of Kurdistan Province) [PDF]

بوم‌شناسی آبزیان, 2017
The estimation of fish potential production and trophic status are two important and necessary parts of fisheries management in lakes. This study was conducted to determinate the trophic status and fish production potential of Golbolagh Lake, for one ...
