Modelling Primate Behavioral Ecology

International Journal of Primatology, 2002
Models play an important role in any mature science because they force us to make explicit our assumptions about how a phenomenon works and allow us to explore the way in which different variables influence a complex biological system. I review the principal kinds of models that could be used to study primate behavior and ecology: linear programming ...

Nanowires Reinforce Oriented Macroporous Aerogels for Rapid Uranium Removal from Acidic Radioactive Wastewater

Advanced Science, EarlyView.
A “reinforced concrete” structural aerogel with directional microchannels is engineered for rapid uranium capture. The interconnected architecture enables ultrafast water permeation, and the nanowire reinforcement yields a 70‐fold increase in mechanical strength.

D–A Type Perylene Micelles With Synergistic Charge/Energy Transfer for Dual‐Path ROS Generation and Enhanced Photocatalysis

Advanced Science, EarlyView.
Dual‐state activation of singlet and triplet excitons is achieved in perylene‐based nanomicelles via donor engineering. By synergistically pairing charge transfer with energy transfer pathways, while concurrently enabling pollutant pre‐enrichment, this strategy establishes spatial coupling between efficient ROS generation and rapid mineralization ...

Nocturnal position in the Panamanian Golden Frog, Atelopus zeteki (Anura, Bufonidae), with notes on fluorescent pigment tracking

Phyllomedusa: Journal of Herpetology, 2007
The endangered Panamanian golden frog, Atelopus zeteki, is a stream dweller of middle elevation rain forests of the Panamanian isthmus. In order to better understand this species for conservation, we set out to determine the nocturnal whereabouts of this

Targeted β‐Glucan‐Veiled Oral Apremilast Nanotherapy Modulates Key Dysbiosis‐Associated Gut Microbiota and Alleviates Ulcerative Colitis‐Associated Anxiety, Depression, and Neuropsychiatric Behaviors

Advanced Science, EarlyView.
This study introduces β‐glucan‐shielded apremilast laden nanomicelles that withstand gastrointestinal degradation, selectively accumulate in inflamed colon tissue, and modulate the microbiota–gut–brain axis. The formulation restores barrier integrity, reduces systemic and neuroinflammation, and improves anxiety‐ and depression‐like behaviors in colitis

Imprinted or innate food preferences in the model mite Archegozetes longisetosus (Actinotrichida, Oribatida, Trhypochthoniidae)

Soil Organisms, 2018
Most oribatid mites are opportunistic feeders with a broad variety of different food sources. However, preferences for certain food such as dark pigmented fungi, led to the ‘choosy generalist’-hypothesis.

LRG1 Drives Pathological Angiogenesis by Disrupting Neutrophil Mitochondrial Homeostasis in Bladder Cancer

Advanced Science, EarlyView.
In bladder cancer, LRG1 binds to ANXA2 to trigger mitochondrial ROS‐dependent NETosis. This pathogenic cascade actively uncouples endothelial‐mural cell interactions, driving profound vascular destabilization. Consequently, targeting the LRG1‐ANXA2 axis attenuates the neutrophil burden and induces structural vascular normalization, offering a powerful ...

Resource gradients create energy trade‐offs in the inducible defense response of Paramecium aurelia

Ecosphere
Ecological communities are structured by inter‐ and intraspecific interactions. The stability of communities is governed by the strength and number of species interactions.
