Species variability in the relative strength of intraspecific and interspecific interactions

open access: yesFolia Oecologica, 2022
Understanding cases in restoration and in agriculture in which species diversity improves productivity and ecosystem functioning is crucial due the need to restore degraded habitat and improve crop productivity for a growing human population.

Interactions between seals and salmon fisheries in Tana River and Tanafjord, Finnmark, North Norway, and possible consequences for the harbour seal Phoca vitulina

open access: yesFauna Norvegica, 1997
In the 1820’s, a relatively large harbour seal population may have inhabited the Tana River Estuary. Due to heavy persecution, especially in the 1920’s and 1930’s, it was reduced dramatically, and today there are probably less than 40 individuals left ...

THE EFFECTS OF INTERSPECIFIC COMPETITION ON THE DYNAMICS OF A POLYMORPHISM IN AN EXPERIMENTAL POPULATION OF DROSOPHILA MELANOGASTER [PDF]

open access: yesGenetics, 1979
ABSTRACT Populations of Drosophila melanogaster with a fourth-chromosome polymorphism were subjected to different levels of competition with Drosophila simulans. The dynamics of the polymorphism and the equilibrium frequencies of the sparkling allele were seen to depend on the competitive level, while the higher productivity of the ...

Data from: Ontogenetic and interspecific scaling of consumption in insects

open access: yes, 2015
The uptake of resources from the environment is a basic feature of all life. Consumption rate has been found to scale with body size with an exponent close to unity across diverse organisms.

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

open access: yesFEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

A Long‐Lived Human Neurovascular PENTA Culture Model Captures Incomplete Vascular Repair and Glia‐Associated Signaling After Traumatic Brain Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
A long‐lived, five‐cell‐type human neurovascular (PENTA) model recreates vascular disorganization and incomplete repair after traumatic brain injury (TBI). By integrating endothelial, glial, neuronal, and immune components within a 3D scaffold, the platform enables time‐resolved analysis of neurovascular remodeling and provides a human‐relevant system ...

Studies of the Helminth Fauna of Norway XL: The Common Gull, Larus canus L., as final host for Cestoda (Platyhelminthes)

open access: yesFauna Norvegica, 1985
In a sample of 269 Common Gulls collected on the west coast of Norway (Agdenes 63°35'N, 9°45'E), 11 different cestode species from three orders were recovered: Anomotaenia micracantha, Choanotaenia larimarina, Dilepis undula, Paricterotaenia porosa ...

Data from: Ontogenetic and interspecific metabolic scaling in insects

open access: yes, 2014
Design constraints imposed by increasing size cause metabolic rate in animals to increase more slowly than mass. This ubiquitous biological phenomenon is referred to as metabolic scaling.

Self‐Assembled Skin Equivalents with Monoclonal CRISPR/Cas9‐Modified N/TERT‐1 Keratinocytes: A Cutting‐Edge model for Human Skin and its Diseases

open access: yesAdvanced Healthcare Materials, EarlyView.
Self‐assembled, scaffold‐free full‐thickness skin equivalents with monoclonal, genetically modified N/TERT‐1 keratinocytes represent a novel in vitro model of human skin and skin diseases. The model is highly robust, reproducible, physiologically relevant, and suitable for high‐throughput applications.
