Inclusion Complexations of Levamisole and Cocaine With Molecular Baskets. Fluorescence Displacement Assay for Detection of Cocaine and Its Adulterant Levamisole in Aqueous Media

open access: yesChemistry – A European Journal, EarlyView.
Levamisole is a common adulterant found in street‐distributed cocaine. Molecular baskets have been shown to form stable inclusion complexes with both substances. While levamisole inserts its benzene into the basket's cavity, cocaine utilizes its bicyclic ring for encapsulation.

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

open access: yesChemistry – A European Journal, EarlyView.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

open access: yesDeep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

open access: yesEcography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

The Role of Biotic and Abiotic Variables in Determining Demographic Processes in an Eelgrass Meadow

open access: yes, 2004
Using principal component analysis among biotic and abiotic variables we found coherent subsets of variables that explain biological processes such as growth, mortality and recruitment in a seagrass (Zostera marina) meadow.

Developing a macroecology for human‐altered ecosystems

open access: yesEcography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

open access: yesEcography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.
